[Back to Build Instructions] [Back to README]
Go to MPV’s home and open the Installation page and click the Windows builds by shinchiro (releases and git) link to get to the files. Then you can choose to install either the git version (64bit or 32bit), or the latest stable release which also provides both 64 and 32 bit binaries.
Note: I am stating here all the links, although all one has to do is get to the last one and download the MPV setup. This is done so that in case any of the links change in the future, the way to go will be known, having MPV’s home page as a starting point.
You will end up downloading a 7z archive, which contains a directory whose name is similar to mpv-0.34.-x86_64.7z.
Extract this archive to whatever place you like and rename it to mpv.
Here comes the tricky part…
Move the mpv directory to either on of the following locations:
This is actually your “Home” directory.
Please make a note that you will add “%USERPROFILE%\mpv to PATH.
This is (or will be) “PyRadio’s configuration directory”.
In case the pyradio directory does not exit, you just go ahead and create it.
(Make a note that you will add “%APPDATA%\pyradio\mpv to PATH)
In either case, in order to do that, open an Explorer File Manager window, and enter at its location field %USERPROFILE% or %APPDATA%.
If you are unsure on how to do that, please refer to the following image (you can ENTER %USERPROFILE% or %APPDATA% or any other Windows System Variable this way).
The final step is to add MPV to the PATH System Variable.
Now, you already know the path string that has to be added (you have made a note of it in the previous step).
There’s just one thing to say here: Windows provide a “User variable for User” and a “System variables” section in the “Environment Variables” window.
Add the path string to the “User variables for User” section.
In order to make the actual addition, please refer to the following image.
Note: This image is the one used in the relevant mplayer page; in this case you just replace mplayer with mpv.
After applying the changes you should log off and back on or restart the system, because changes done to the PATH variable will take effect the next time you log into the system.
When you are back on, verify that you can run MPV; open a console (press the Win key, type cmd and press ENTER) and type “mpv”.
If you get something similar to the following snippet, you are all good.
mpv 0.34.0 Copyright © 2000-2021 mpv/MPlayer/mplayer2 projects built on Sun Nov 7 20:16:38 +08 2021 FFmpeg library versions: libavutil 57.7.100 libavcodec 59.12.100 libavformat 59.8.100 libswscale 6.1.100 libavfilter 8.16.101 libswresample 4.0.100 FFmpeg version: git-2021-11-06-1728127e Usage: mpv [options] [url|path/]filename Basic options: --start=<time> seek to given (percent, seconds, or hh:mm:ss) position --no-audio do not play sound --no-video do not play video --fs fullscreen playback --sub-file=<file> specify subtitle file to use --playlist=<file> specify playlist file --list-options list all mpv options --h=<string> print options which contain the given string in their name
If mpv was not found, you just have to go through the PATH modification procedure again.


A package to create ASCII art from arbitrary images. This is very much a work in progress and probably doesn’t have a purpose, but I’m finding it fun.
# devtools::install_github("djnavarro/asciify")
library("asciify")
#> Registered S3 methods overwritten by 'ggplot2':
#> method from
#> [.quosures rlang
#> c.quosures rlang
#> print.quosures rlang
The core function in the package is ascii_map
, which takes a path to an image file as the input, and returns a tibble converting the image to a character map:
bayes_img <- ascii_data("bayes.png") # path to the bayes image
bayes_map <- ascii_map(file = bayes_img) # construct ASCII map
bayes_map
#> # A tibble: 1,404 x 3
#> x y label
#> <int> <int> <chr>
#> 1 44 2 r
#> 2 45 2 v
#> 3 46 2 b
#> 4 47 2 e
#> 5 48 2 o
#> 6 41 3 y
#> 7 42 3 u
#> 8 43 3 e
#> 9 44 3 s
#> 10 45 3 o
#> # … with 1,394 more rows
In the code chunk above ascii_data
is just a convenience function that returns the path to an image file that comes bundled with the package.
The tibble has three variables: x
and y
specify the location of a character on a grid, and label
specifes what character is shown at that location. The package includes a simple plot function that returns a ggplot:
There are a few other handy functions in the package.
Once converted to this grid format, you can write it to text file using ascii_text
Finally, for no particularly sensible reasion, the package also allows you to write the result to an HTML file that produces a “digital rain” animation.


Welcome to my About Me page!
My name is Jennifer and I originally grew up in the San Fernando Valley in Southern California with my mom and her cats. These days I live in West Seattle with my husband, my brother-in-law, two sugar gliders named Attila and Cicero, and a lot of house plants.
Education
- After high school I moved north to attend college at UC Santa Cruz.
- While there I majored in Literature but spent most of my time with the Theater Department as a lighting designer and electrician.
- I also minored in Education.
Work Experience
- While I was still a college student I worked as an electrician for the local summer Shakespeare festival that at the time staged productions on the UCSC campus. It was my first paid position and I have a lot of fond memories from that period of life.
- After graduating, I spent several years working in early childhood education as a preschool teaching assistant - first in Northern California and then later in Seattle. While I found the work very rewarding, I realized that it wasn't a career path I wanted to continue down.
- The next few years were spent with an eco-conscious cleaning company where I worked initially as a house cleaner and then later as a scheduler and office manager.
- I transitioned from this role to a direct sales position with a custom mensware company that had recently launched in the area. However, the Seattle grunge aesthetic really isn't very conducive to high end mens fashion, and so while I picked up some excellent networking skills I realized that the job itself wasn't meant to be a long term fit.
- From there I moved on to a small tech startup in the renewable energy sector that was in need of an office manager and general assistance with operations (including construction of metering devices that took me back to my electrician days - a highlight of that job!).
- Last year I decided to take a break from the office setting and took a job at my local Trader Joe's as a crew member. It was a great reset for me - allowing me to clear my head and reexamine what my priorities are while also introducing me to some amazing new friends.
I'm not sure what the next step in my working life looks like, but I'm excited to see what doors may open once I have a firm understanding of the basics of coding.
You may have guessed by now that I love to read! It's hard to name a difinitive top 10 list of books - there are just so many good ones to choose from - but here are 10 of the most influential books I've read so far:
- The Handmaid's Tale by Margaret Atwood
- Jane Eyre by Charlotte Bronte
- A Clockwork Orange by Anthony Burgess
- Me Talk Pretty One Day by David Sedaris
- Cloud Atlas by David Mitchell
- The City & the City by China Mieville
- The Fifth Season by N.K. Jemisin
- The Hobbit, or There and Back Again by J.R.R. Tolkien
- Written on the Body by Jeanette Winterson
- Sabriel by Garth Nix
I've included links to the Goodreads page for each so that you can see what other people have to say about them as well - books are always more enjoyable when you can discuss them with friends.

enum class TreeGenerationMode
Represents the different types of tree generation methods.
Grow mode will generate trees with nodes chosen randomly from the union of the function and terminal sets, allowing trees that are smaller than the max depth to be created. This method generally produces asymmetric trees.
Full mode will generates tree with nodes chosen from the function set, until the maximum depth is reached when it will start choosing from the terminal set. This tends to grow "bushy" symmetrical trees.
HalfAndHalf mode will use a 50/50 combination of the full and grow modes, meaning the trees in the initial population will have a mix of shapes.

PERLINTRO
Section: Perl Programmers Reference Guide (1)Updated: 2009-02-12
Index Return to Main Contents
NAME
perlintro -- a brief introduction and overview of PerlDESCRIPTION
This document is intended to give you a quick overview of the Perl programming language, along with pointers to further documentation. It is intended as a ``bootstrap'' guide for those who are new to the language, and provides just enough information for you to be able to read other peoples' Perl and understand roughly what it's doing, or write your own simple scripts.This introductory document does not aim to be complete. It does not even aim to be entirely accurate. In some cases perfection has been sacrificed in the goal of getting the general idea across. You are strongly advised to follow this introduction with more information from the full Perl manual, the table of contents to which can be found in perltoc.
Throughout this document you'll see references to other parts of the Perl documentation. You can read that documentation using the "perldoc" command or whatever method you're using to read this document.
What is Perl?
Perl is a general-purpose programming language originally developed for text manipulation and now used for a wide range of tasks including system administration, web development, network programming, GUI development, and more.The language is intended to be practical (easy to use, efficient, complete) rather than beautiful (tiny, elegant, minimal). Its major features are that it's easy to use, supports both procedural and object-oriented (OO) programming, has powerful built-in support for text processing, and has one of the world's most impressive collections of third-party modules.
Different definitions of Perl are given in perl, perlfaq1 and no doubt other places. From this we can determine that Perl is different things to different people, but that lots of people think it's at least worth writing about.
Running Perl programs
To run a Perl program from the Unix command line:
perl progname.pl
Alternatively, put this as the first line of your script:
#!/usr/bin/env perl
... and run the script as "/path/to/script.pl". Of course, it'll need to be executable first, so "chmod 755 script.pl" (under Unix).
(This start line assumes you have the env program. You can also put directly the path to your perl executable, like in "#!/usr/bin/perl").
For more information, including instructions for other platforms such as Windows and Mac OS, read perlrun.
Safety net
Perl by default is very forgiving. In order to make it more robust it is recommended to start every program with the following lines:
#!/usr/bin/perl use strict; use warnings;
The two additional lines request from perl to catch various common problems in your code. They check different things so you need both. A potential problem caught by "use strict;" will cause your code to stop immediately when it is encountered, while "use warnings;" will merely give a warning (like the command-line switch -w) and let your code run. To read more about them check their respective manual pages at strict and warnings.
Basic syntax overview
A Perl script or program consists of one or more statements. These statements are simply written in the script in a straightforward fashion. There is no need to have a "main()" function or anything of that kind.Perl statements end in a semi-colon:
print "Hello, world";
Comments start with a hash symbol and run to the end of the line
# This is a comment
Whitespace is irrelevant:
print "Hello, world" ;
... except inside quoted strings:
# this would print with a linebreak in the middle print "Hello world";
Double quotes or single quotes may be used around literal strings:
print "Hello, world"; print 'Hello, world';
However, only double quotes ``interpolate'' variables and special characters such as newlines ("\n"):
print "Hello, $name\n"; # works fine print 'Hello, $name\n'; # prints $name\n literally
Numbers don't need quotes around them:
print 42;
You can use parentheses for functions' arguments or omit them according to your personal taste. They are only required occasionally to clarify issues of precedence.
print("Hello, world\n"); print "Hello, world\n";
More detailed information about Perl syntax can be found in perlsyn.
Perl variable types
Perl has three main variable types: scalars, arrays, and hashes.- Scalars
-
A scalar represents a single value:
my $animal = "camel"; my $answer = 42;
Scalar values can be strings, integers or floating point numbers, and Perl will automatically convert between them as required. There is no need to pre-declare your variable types, but you have to declare them using the "my" keyword the first time you use them. (This is one of the requirements of "use strict;".)
Scalar values can be used in various ways:
print $animal; print "The animal is $animal\n"; print "The square of $answer is ", $answer * $answer, "\n";
There are a number of ``magic'' scalars with names that look like punctuation or line noise. These special variables are used for all kinds of purposes, and are documented in perlvar. The only one you need to know about for now is $_ which is the ``default variable''. It's used as the default argument to a number of functions in Perl, and it's set implicitly by certain looping constructs.
print; # prints contents of $_ by default
- Arrays
-
An array represents a list of values:
my @animals = ("camel", "llama", "owl"); my @numbers = (23, 42, 69); my @mixed = ("camel", 42, 1.23);
Arrays are zero-indexed. Here's how you get at elements in an array:
print $animals[0]; # prints "camel" print $animals[1]; # prints "llama"
The special variable $#array tells you the index of the last element of an array:
print $mixed[$#mixed]; # last element, prints 1.23
You might be tempted to use "$#array + 1" to tell you how many items there are in an array. Don't bother. As it happens, using @array where Perl expects to find a scalar value (``in scalar context'') will give you the number of elements in the array:
if (@animals < 5) { ... }
The elements we're getting from the array start with a "$" because we're getting just a single value out of the array --- you ask for a scalar, you get a scalar.
To get multiple values from an array:
@animals[0,1]; # gives ("camel", "llama"); @animals[0..2]; # gives ("camel", "llama", "owl"); @animals[1..$#animals]; # gives all except the first element
This is called an ``array slice''.
You can do various useful things to lists:
my @sorted = sort @animals; my @backwards = reverse @numbers;
There are a couple of special arrays too, such as @ARGV (the command line arguments to your script) and @_ (the arguments passed to a subroutine). These are documented in perlvar.
- Hashes
-
A hash represents a set of key/value pairs:
my %fruit_color = ("apple", "red", "banana", "yellow");
You can use whitespace and the "=>" operator to lay them out more nicely:
my %fruit_color = ( apple => "red", banana => "yellow", );
To get at hash elements:
$fruit_color{"apple"}; # gives "red"
You can get at lists of keys and values with "keys()" and "values()".
my @fruits = keys %fruit_colors; my @colors = values %fruit_colors;
Hashes have no particular internal order, though you can sort the keys and loop through them.
Just like special scalars and arrays, there are also special hashes. The most well known of these is %ENV which contains environment variables. Read all about it (and other special variables) in perlvar.
Scalars, arrays and hashes are documented more fully in perldata.
More complex data types can be constructed using references, which allow you to build lists and hashes within lists and hashes.
A reference is a scalar value and can refer to any other Perl data type. So by storing a reference as the value of an array or hash element, you can easily create lists and hashes within lists and hashes. The following example shows a 2 level hash of hash structure using anonymous hash references.
my $variables = { scalar => { description => "single item", sigil => '$', }, array => { description => "ordered list of items", sigil => '@', }, hash => { description => "key/value pairs", sigil => '%', }, }; print "Scalars begin with a $variables->{'scalar'}->{'sigil'}\n";
Exhaustive information on the topic of references can be found in perlreftut, perllol, perlref and perldsc.
Variable scoping
Throughout the previous section all the examples have used the syntax:
my $var = "value";
The "my" is actually not required; you could just use:
$var = "value";
However, the above usage will create global variables throughout your program, which is bad programming practice. "my" creates lexically scoped variables instead. The variables are scoped to the block (i.e. a bunch of statements surrounded by curly-braces) in which they are defined.
my $x = "foo"; my $some_condition = 1; if ($some_condition) { my $y = "bar"; print $x; # prints "foo" print $y; # prints "bar" } print $x; # prints "foo" print $y; # prints nothing; $y has fallen out of scope
Using "my" in combination with a "use strict;" at the top of your Perl scripts means that the interpreter will pick up certain common programming errors. For instance, in the example above, the final "print $y" would cause a compile-time error and prevent you from running the program. Using "strict" is highly recommended.
Conditional and looping constructs
Perl has most of the usual conditional and looping constructs except for case/switch (but if you really want it, there is a Switch module in Perl 5.8 and newer, and on CPAN. See the section on modules, below, for more information about modules and CPAN).The conditions can be any Perl expression. See the list of operators in the next section for information on comparison and boolean logic operators, which are commonly used in conditional statements.
- if
-
if ( condition ) { ... } elsif ( other condition ) { ... } else { ... }
There's also a negated version of it:
unless ( condition ) { ... }
This is provided as a more readable version of "if (!condition)".
Note that the braces are required in Perl, even if you've only got one line in the block. However, there is a clever way of making your one-line conditional blocks more English like:
# the traditional way if ($zippy) { print "Yow!"; } # the Perlish post-condition way print "Yow!" if $zippy; print "We have no bananas" unless $bananas;
- while
-
while ( condition ) { ... }
There's also a negated version, for the same reason we have "unless":
until ( condition ) { ... }
You can also use "while" in a post-condition:
print "LA LA LA\n" while 1; # loops forever
- for
-
Exactly like C:
for ($i = 0; $i <= $max; $i++) { ... }
The C style for loop is rarely needed in Perl since Perl provides the more friendly list scanning "foreach" loop.
- foreach
-
foreach (@array) { print "This element is $_\n"; } print $list[$_] foreach 0 .. $max; # you don't have to use the default $_ either... foreach my $key (keys %hash) { print "The value of $key is $hash{$key}\n"; }
For more detail on looping constructs (and some that weren't mentioned in this overview) see perlsyn.
Builtin operators and functions
Perl comes with a wide selection of builtin functions. Some of the ones we've already seen include "print", "sort" and "reverse". A list of them is given at the start of perlfunc and you can easily read about any given function by using "perldoc -f functionname".Perl operators are documented in full in perlop, but here are a few of the most common ones:
- Arithmetic
-
+ addition - subtraction * multiplication / division
- Numeric comparison
-
== equality != inequality < less than > greater than <= less than or equal >= greater than or equal
- String comparison
-
eq equality ne inequality lt less than gt greater than le less than or equal ge greater than or equal
(Why do we have separate numeric and string comparisons? Because we don't have special variable types, and Perl needs to know whether to sort numerically (where 99 is less than 100) or alphabetically (where 100 comes before 99).
- Boolean logic
-
&& and || or ! not
("and", "or" and "not" aren't just in the above table as descriptions of the operators --- they're also supported as operators in their own right. They're more readable than the C-style operators, but have different precedence to "&&" and friends. Check perlop for more detail.)
- Miscellaneous
-
= assignment . string concatenation x string multiplication .. range operator (creates a list of numbers)
Many operators can be combined with a "=" as follows:
$a += 1; # same as $a = $a + 1 $a -= 1; # same as $a = $a - 1 $a .= "\n"; # same as $a = $a . "\n";
Files and I/O
You can open a file for input or output using the "open()" function. It's documented in extravagant detail in perlfunc and perlopentut, but in short:
open(my $in, "<", "input.txt") or die "Can't open input.txt: $!"; open(my $out, ">", "output.txt") or die "Can't open output.txt: $!"; open(my $log, ">>", "my.log") or die "Can't open my.log: $!";
You can read from an open filehandle using the "<>" operator. In scalar context it reads a single line from the filehandle, and in list context it reads the whole file in, assigning each line to an element of the list:
my $line = <$in>; my @lines = <$in>;
Reading in the whole file at one time is called slurping. It can be useful but it may be a memory hog. Most text file processing can be done a line at a time with Perl's looping constructs.
The "<>" operator is most often seen in a "while" loop:
while (<$in>) { # assigns each line in turn to $_ print "Just read in this line: $_"; }
We've already seen how to print to standard output using "print()". However, "print()" can also take an optional first argument specifying which filehandle to print to:
print STDERR "This is your final warning.\n"; print $out $record; print $log $logmessage;
When you're done with your filehandles, you should "close()" them (though to be honest, Perl will clean up after you if you forget):
close $in or die "$in: $!";
Regular expressions
Perl's regular expression support is both broad and deep, and is the subject of lengthy documentation in perlrequick, perlretut, and elsewhere. However, in short:- Simple matching
-
if (/foo/) { ... } # true if $_ contains "foo" if ($a =~ /foo/) { ... } # true if $a contains "foo"
The "//" matching operator is documented in perlop. It operates on $_ by default, or can be bound to another variable using the "=~" binding operator (also documented in perlop).
- Simple substitution
-
s/foo/bar/; # replaces foo with bar in $_ $a =~ s/foo/bar/; # replaces foo with bar in $a $a =~ s/foo/bar/g; # replaces ALL INSTANCES of foo with bar in $a
The "s///" substitution operator is documented in perlop.
- More complex regular expressions
-
You don't just have to match on fixed strings. In fact, you can match
on just about anything you could dream of by using more complex regular
expressions. These are documented at great length in perlre, but for
the meantime, here's a quick cheat sheet:
. a single character \s a whitespace character (space, tab, newline, ...) \S non-whitespace character \d a digit (0-9) \D a non-digit \w a word character (a-z, A-Z, 0-9, _) \W a non-word character [aeiou] matches a single character in the given set [^aeiou] matches a single character outside the given set (foo|bar|baz) matches any of the alternatives specified ^ start of string $ end of string
Quantifiers can be used to specify how many of the previous thing you want to match on, where ``thing'' means either a literal character, one of the metacharacters listed above, or a group of characters or metacharacters in parentheses.
* zero or more of the previous thing + one or more of the previous thing ? zero or one of the previous thing {3} matches exactly 3 of the previous thing {3,6} matches between 3 and 6 of the previous thing {3,} matches 3 or more of the previous thing
Some brief examples:
/^\d+/ string starts with one or more digits /^$/ nothing in the string (start and end are adjacent) /(\d\s){3}/ a three digits, each followed by a whitespace character (eg "3 4 5 ") /(a.)+/ matches a string in which every odd-numbered letter is a (eg "abacadaf") # This loop reads from STDIN, and prints non-blank lines: while (<>) { next if /^$/; print; }
- Parentheses for capturing
-
As well as grouping, parentheses serve a second purpose. They can be
used to capture the results of parts of the regexp match for later use.
The results end up in $1, $2 and so on.

- Other regexp features
- Perl regexps also support backreferences, lookaheads, and all kinds of other complex details. Read all about them in perlrequick, perlretut, and perlre.
Writing subroutines
Writing subroutines is easy:
sub logger { my $logmessage = shift; open my $logfile, ">>", "my.log" or die "Could not open my.log: $!"; print $logfile $logmessage; }
Now we can use the subroutine just as any other built-in function:
logger("We have a logger subroutine!");
What's that "shift"? Well, the arguments to a subroutine are available to us as a special array called @_ (see perlvar for more on that). The default argument to the "shift" function just happens to be @_. So "my $logmessage = shift;" shifts the first item off the list of arguments and assigns it to $logmessage.
We can manipulate @_ in other ways too:
my ($logmessage, $priority) = @_; # common my $logmessage = $_[0]; # uncommon, and ugly
Subroutines can also return values:
sub square { my $num = shift; my $result = $num * $num; return $result; }
Then use it like:
$sq = square(8);
For more information on writing subroutines, see perlsub.
OO Perl
OO Perl is relatively simple and is implemented using references which know what sort of object they are based on Perl's concept of packages. However, OO Perl is largely beyond the scope of this document. Read perlboot, perltoot, perltooc and perlobj.As a beginning Perl programmer, your most common use of OO Perl will be in using third-party modules, which are documented below.
Using Perl modules
Perl modules provide a range of features to help you avoid reinventing the wheel, and can be downloaded from CPAN ( http://www.cpan.org/ ). A number of popular modules are included with the Perl distribution itself.Categories of modules range from text manipulation to network protocols to database integration to graphics. A categorized list of modules is also available from CPAN.
To learn how to install modules you download from CPAN, read perlmodinstall.
To learn how to use a particular module, use "perldoc Module::Name". Typically you will want to "use Module::Name", which will then give you access to exported functions or an OO interface to the module.
perlfaq contains questions and answers related to many common tasks, and often provides suggestions for good CPAN modules to use.
perlmod describes Perl modules in general. perlmodlib lists the modules which came with your Perl installation.
If you feel the urge to write Perl modules, perlnewmod will give you good advice.

JS9 supports a site configuration file that is read after the JavaScript variables are loaded but before JavaScript code is compiled and executed. This file allow you to tailor JS9 to meet the needs of your site without having to modify the js9.js file directly.
To support site configuration, JS9 tries to load a json file called
js9Prefs.json from the same server on which the main
js9-[version].js file resides. The file will be looked for first in
the same directory as the web page and then in the js9 install directory.
(Firefox has deprecated synchronous XHR requests in the main
window. As a result, we have been forced to deprecate automatic loading of
the js9Prefs.json file. Please use js9prefs.js instead.)
To support site configuration, load the JS9 json preference file file (referred to here as js9prefs.json, but it can be named anything, of course) into your web page before loading other JS9 javascript:
<script type="text/javascript" src="js9prefs-local.js"></script> <script type="text/javascript" src="js9support.min.js"></script> <script type="text/javascript" src="js9.min.js"></script> ...
NB: the JS9 Node.js helper still utilizes the js9Prefs.json file. Please ensure that the properties defined in these two files are consistent.
This preference file can be used to override the default parameter settings for JS9. A look through the beginning of JS9 code will show a number of Javascript objects containing these default parameters. They all have names ending in Opts, i.e. JS9.imageOpts, JS9.analysisOpts, etc. A description of some of these objects is given below:
JS9.globalOpts: this JavaScript object contains global information, including parameters concerned with the back-end services used by JS9. Currently, it allows you to specify the helperPort on which to connect. Note that this same preference file is read the Node-based js9Helper, so changing the helper port in this file will change both the client and server.
JS9.imageOpts: This JavaScript object contains initial values for image parameters such as: contrast, bias, whether to invert the colormap, colormap, scale, WCS system , WCS units, whether to display value/position, and whether to list regions when they change (listonchange).
JS9.analOpts This JavaScript object contains the dataDir option, which specifies the pathname prefix to add to each FITS filename instead of the pathname stored in the PNG file. You can set this variable if you have moved the location of the raw FITS files after generating the PNG files.
JS9.Regions.opts: This JavaScript object contains default values for regions, including the initial size of various regions, initial inner and outer radii for annuli, initial angle, etc. You can set or override properties for this object by adding them to the regionOpts object in the js9prefs.js file.
JS9.menuButtonOptsArr: this JavaScript array of objects allows you to change and re-arrange which menu options are provided. If you prefix the name of a menu option with '#', that option is disabled.
Module: a global JavaScript object with attributes that Emscripten-generated code calls at various points in its execution. You can set or override properties for this object by adding them to the emscriptenOpts object in the js9prefs.js file. One important case occurs when you have installed the astroemw.wasm binary file in a location other than the JS9 install directory. You would then use Emscripten's wasmBinaryFile property to specify a path to this file, relative to the JS9 install directory. For example, if the JS9 install directory and the resources directory are at the same level in the directory hierarchy:
var JS9Prefs = { "emscriptenOpts": { "wasmBinaryFile": "../resources/js/astroemw.wasm" }, # other preferences ... }See Emscripten's Module Object documentation for more information, and please let us know if you have problems.

API to the JsonParser.
This is a memory-efficient JSON parser based on jsmn. It only keeps one copy of the data in raw format and an array of tokens. You make calls to read values out.
| JsonParser::JsonParser | ( | ) |
Construct a parser object.
This version dynamically allocates the buffer and token storage. If you want to minimize memory allocations you can pass in a static buffer and array of tokens to use instead.
|
virtual |
Destroy a parser object.
If the buffer was allocated dynamically it will be deleted. If you passed in a static buffer the static buffer is not deleted.
| bool JsonParser::allocateTokens | ( | size_t | maxTokens | ) |
Preallocates a specific number of tokens.
Optional: You should set this larger than the expected number of tokens for efficiency, but if you are not using the static allocator it will resize the token storage space if it's too small.
| void JsonParser::copyTokenValue | ( | const JsonParserGeneratorRK::jsmntok_t * | token, |
| char * | dst, | ||
| size_t | dstLen | ||
| ) | const |
Copies the value of the token into a buffer, making it a null-terminated cstring.
If the string is longer than dstLen - 1 bytes, it will be truncated and the result will still be a valid cstring.
This is used internally because the token data is not null-terminated, and doing things like sscanf or strtoul on it can read past the end of the buffer. This assures that only null-terminated data is passed to these functions.
| size_t JsonParser::getArraySize | ( | const JsonParserGeneratorRK::jsmntok_t * | arrayContainer | ) | const |
Given a token for an JSON array in arrayContainer, gets the number of elements in the array.
0 = no elements, 1 = one element, ...
The index values for getValueByIndex(), etc. are 0-based, so the last index you pass in is less than getArraySize().
|
inline |
Gets the key/value pair of an object by index.
| container | The object to look in (see getOuterKeyValueByIndex if you want to the outermost object you parsed) |
| index | 0 = first, 1 = second, ... |
| key | Filled in with the name of the key |
| result | Filled in with the value. The value can be of type: bool, int, unsigned long, float, double, String, or (char *, size_t&). |
Normally you get a value in an object by its key, but if you want to iterate all of the keys you can use this method. Call it until it returns false.
This should only be used for things like string, numbers, booleans, etc.. If you want to get a JSON array or object within an object, use getValueTokenByKey() instead.
| bool JsonParser::getKeyValueTokenByIndex | ( | const JsonParserGeneratorRK::jsmntok_t * | container, |
| const JsonParserGeneratorRK::jsmntok_t *& | key, | ||
| const JsonParserGeneratorRK::jsmntok_t *& | value, | ||
| size_t | index | ||
| ) | const |
Given a JSON object in container, gets the key/value pair specified by index. Internal use only.
| container | The array token to look in. |
| key | Filled in with the key token for nth key value pair. |
| value | Filled in with the value token for then nth key value pair. |
| index | The index to retrieve (0 = first, 1 = second, ...). |
This is a low-level function; you will typically use getValueByIndex() or getValueByKey() instead.
| const JsonParserGeneratorRK::jsmntok_t * JsonParser::getOuterArray | ( | ) | const |
Gets the outer JSON array token.
Sometimes the JSON will contain an array of values (or objects) instead of starting with an object. This gets the outermost array.
A token (JsonParserGeneratorRK::jsmntok_t) identifies a particular piece of data in the JSON data, such as an object, array, or element within an object or array, such as a string, integer, boolean, etc..
|
inline |
Gets the key/value pair of the outer object by index (0 = first, 1 = second, ...)
Normally you get a value in an object by its key, but if you want to iterate all of the keys you can use this method.
| index | 0 = first, 1 = second, ... |

| const JsonParserGeneratorRK::jsmntok_t * JsonParser::getOuterObject | ( | ) | const |
Gets the outer JSON object token.
Typically JSON will contain an object that contains values and possibly other objects. This method gets the token for the outer object.
A token (JsonParserGeneratorRK::jsmntok_t) identifies a particular piece of data in the JSON data, such as an object, array, or element within an object or array, such as a string, integer, boolean, etc..
| const JsonParserGeneratorRK::jsmntok_t * JsonParser::getOuterToken | ( | ) | const |
Gets the outer JSON object or array token.
A token (JsonParserGeneratorRK::jsmntok_t) identifies a particular piece of data in the JSON data, such as an object, array, or element within an object or array, such as a string, integer, boolean, etc..
|
inline |
Gets the value with the specified key name out of the outer object.
| name | The name of the key to retrieve |
| result | The returned data. |
The outer object must be a JSON object, not an array.
This should only be used for things like string, numbers, booleans, etc.. If you want to get a JSON array or object within an object, use getValueTokenByKey() instead.
| const JsonParserGeneratorRK::jsmntok_t * JsonParser::getTokenByIndex | ( | const JsonParserGeneratorRK::jsmntok_t * | container, |
| size_t | desiredIndex | ||
| ) | const |
Given a containing object, finds the nth token in the object. Internal use only.
| container | The array token to look in. |
| desiredIndex | The index to retrieve (0 = first, 1 = second, ...). |
This is used internally. It should not be used to get the nth array value, use getValueTokenByIndex instead.
| bool JsonParser::getTokenJsonString | ( | const JsonParserGeneratorRK::jsmntok_t * | token, |
| String & | result | ||
| ) | const |
Converts a token (object, array, string, or primitive) back into JSON in a Wiring String.
| token | The token to convert back to a string |
| result | Filled in with the string. Any previous contents in the string are cleared first. |
| bool JsonParser::getTokenJsonString | ( | const JsonParserGeneratorRK::jsmntok_t * | token, |
| char * | str, | ||
| size_t & | strLen | ||
| ) | const |
Converts a token (object, array, string, or primitive) back into JSON in a buffer.
| token | The token to convert back to a string |
| str | The buffer to be written to |
| strLen | The length of the buffer on entry, set to the number of bytes written on exit. |
| bool JsonParser::getTokenJsonString | ( | const JsonParserGeneratorRK::jsmntok_t * | token, |
| JsonParserString & | str | ||
| ) | const |
Gets a token as a JSON string.
| token | The token to convert back to a string |
| str | The JsonParserString object to write to |
This overload is typically used internally, normally you'd use the version that takes a String& or char *, size_t.
| bool JsonParser::getTokenValue | ( | const JsonParserGeneratorRK::jsmntok_t * | token, |
| bool & | result | ||
| ) | const |
Gets a bool (boolean) value.
Normally you'd use getValueByKey(), getValueByIndex() or getValueByColRow() which will automatically use this when the result parameter is a bool variable.
| bool JsonParser::getTokenValue | ( | const JsonParserGeneratorRK::jsmntok_t * | token, |
| int & | result | ||
| ) | const |
Gets an integer value.
Normally you'd use getValueByKey(), getValueByIndex() or getValueByColRow() which will automatically use this when the result parameter is an int variable.
| bool JsonParser::getTokenValue | ( | const JsonParserGeneratorRK::jsmntok_t * | token, |
| unsigned long & | result | ||
| ) | const |
Gets an unsigned long value.
Normally you'd use getValueByKey(), getValueByIndex() or getValueByColRow() which will automatically use this when the result parameter is an unsigned long variable.
| bool JsonParser::getTokenValue | ( | const JsonParserGeneratorRK::jsmntok_t * | token, |
| float & | result | ||
| ) | const |
Gets a float (single precision floating point) value.
Normally you'd use getValueByKey(), getValueByIndex() or getValueByColRow() which will automatically use this when the result parameter is a float variable.
| bool JsonParser::getTokenValue | ( | const JsonParserGeneratorRK::jsmntok_t * | token, |
| double & | result | ||
| ) | const |
Gets a double (double precision floating point) value.
Normally you'd use getValueByKey(), getValueByIndex() or getValueByColRow() which will automatically use this when the result parameter is a double variable.
| bool JsonParser::getTokenValue | ( | const JsonParserGeneratorRK::jsmntok_t * | token, |
| String & | result | ||
| ) | const |
Gets a String value into a Wiring String object.
This will automatically decode Unicode character escapes in the data and the returned String will contain UTF-8.
Normally you'd use getValueByKey(), getValueByIndex() or getValueByColRow() which will automatically use this when the result parameter is a String variable.
| bool JsonParser::getTokenValue | ( | const JsonParserGeneratorRK::jsmntok_t * | token, |
| char * | str, | ||
| size_t & | strLen | ||
| ) | const |
Gets a string as a c-string into the specified buffer.
If the token specifies too large of a string it will be truncated. This will automatically decode Unicode character escapes in the data and the returned string will contain UTF-8.
| bool JsonParser::getTokenValue | ( | const JsonParserGeneratorRK::jsmntok_t * | token, |
| JsonParserString & | str | ||
| ) | const |
Gets a string as a JsonParserString object.
This is used internally by getTokenValue() overloads that take a String or buffer and length; you will normally not need to use this directly.
This will automatically decode Unicode character escapes in the data and the returned string will contain UTF-8.

| row | The row (inner array index, 0 = first row, 1 = second row, ...) |
| value | Filled in with the token for the value for key. |
This can be used for 2-dimensional arrays whose values are arrays or objects, to get the token for the container. It can also be used for values, but normally you'd use getValueByColRow() instead, which is generally more convenient.
| bool JsonParser::getValueTokenByIndex | ( | const JsonParserGeneratorRK::jsmntok_t * | container, |

-
Toast the coriander, cumin and mace in a frying pan until fragrant. Add the peppercorns. Remove from the heat and leave to cool. Grind in a pestle and mortar and add to the paste.
-
For the curry, heat the coconut cream. When the cream splits, add the curry paste and fry, stirring constantly over a medium heat. Add the chicken, palm sugar and the fish sauce.

Keep warm over a very low heat while you make the noodles.
-
For the noodles, put the garlic, ginger and coriander in a pestle and mortar and pound to a paste. Heat the oil in a wok and add the paste to the oil, fry at a very high heat for a minute until fragrant and starting to colour.
-
Stir in the chillies and noodles. Add the sauces, mix and when hot put in a large bowl topped with the fresh coriander and beansprouts.
-
Serve the curry with the noodles alongside. Top with the curry garnish, if using.

The smell of mulled wine alone is enough to make the home feel Christmassy - keep a pot of this on hand for visitors.
Carefully peel the zest very thinly from the orange and lemons using a vegetable peeler. Squeeze out the juice and reserve.
Stick the cloves into the satsumas.
Pour the wine, 1.2 litres/2 pints of cold water, and the citrus peel and juices into a large, heavy-based saucepan. Add the clove-studded satsumas and cinnamon sticks. Bring the mixture just to the boil, then reduce the heat until the mixture is simmering, cover the pan with the lid, and continue to simmer for about 1 hour. Stir in the sugar gradually during cooking, until the mulled wine is sweetened to your liking (you may not need all of the sugar).
Strain the mulled wine and serve hot in cups.

The <DuxInput>
component supports custom formatting, parsing, and normalization callbacks.
A formatting callback is called upon to display a value in a format the user can easily read. A parsing callback
is called upon to read a string input by the user and convert it into a value saved in the Redux store. A
normalization callback is called upon to normalize the value input by the user into a the value saved in the
Redux store.
A formatting callback is called when the input field blurs. It formats the value from the Redux store to be displayed in the field input. The function is passed the value and field name and returns the formatted value.
The parsing callback is called whenever the value changes, even as the user types. It parses the value from the input field into the value you want saved in the Redux store. The function is passed the value and the field name and returns the parsed value.
The normalization callback is called when the input field blurs. This is useful when you want to alter the value the user enters before it gets stored in the Redux store. For example, you could convert the string to all lowercase or remove special or undesired characters. The function is passed the value and field name and it returns the normalized value.

Asylo

Copyright 2018 Google Inc.
The Asylo toolchain must be installed to compile enclaves. See distrib/README.md
for more details.
Furthermore, to use the SGX backend, you must have their prerequisites installed. The Asylo SDK uses Intel SGX SDK v1.9, so see their prerequisites https://github.com/intel/linux-sgx/blob/sgx_1.9/README.md "as of their v1.9 release"
The Asylo SDK builds with Bazel, Google's open source build tool. To install it in Ubuntu or Debian, run the following commands:
The SDK uses some extra tools too. Some code generation is done by Python:
$ sudo apt-get install python
Targets for trusted enclave code and enclave test code must be built with a --config
flag that specifies the enclave backend it will use.
For example, build the simple enclave smoke test with the SGX simulation backend with the following command:
bazel build --config=sgx-sim //asylo/test/misc:enclave_smoke_test
For hardware-backed SGX, build with --config=sgx
. Debug enclaves are signed with a key that does not support release builds. See TODO_MISSING_DOCUMENTATION for the SGX release workflow.
Targets that are strictly for untrusted code do not need to be compiled with the --config=BACKEND
flag. All targets in //asylo/platform/common may be used both inside and outside enclaves.


sendiso
Section: Linux IEEE 1394 (1)Updated: libraw1394 2.0.4
Index Return to Main Contents
NAME
sendiso - send IEEE 1394 isochronous packets from dump fileSYNOPSIS
sendiso [ options ] FILEDESCRIPTION
sendiso takes the dump file FILE as generated by dumpiso(1), extracts the packets and sends them as they were received (in the same order, with the same channel numbers) as fast as possible - timing of the original dump is not preserved.This program does not allocate any isochronous resources but just starts sending. It should not be used in live environments where it might interfere with properly set up isochronous transmissions, it is a debug and performance benchmarking tool.
OPTIONS
- -l, --loop=COUNT
- Send dump file COUNT times. Defaults to 1.
- -i, --infinite
- Send dump file in an endless loop.
- -s, --speed=SPEED
- Send packets at speed SPEED, which can be given as 100, 200 and 400 (in Mbit/s) or abbreviated as 1, 2 and 4. Defaults to 100.
- -p, --port=PORT
- Choose port PORT for sending. A port is a 1394 card or chip and represents one connected bus, therefore this is only relevant when you have multiple of these. Defaults to 0.
- -h, --help
- Show help text and exit.

Batting average represents the ratio of hits per at bats. Most baseball hall of famers are known to have career batting averages of above .300, which means that they get a hit around one third of the time. Since 2006, the MLB league batting average has decreased from .269 (2006) to .248 (2018). This also enforces the idea that players are not trying to hit for contact as often as they're trying to hit for power. Players are striking out more often because they are swinging harder, but they are also hitting more homeruns rather than hitting for contact. All in all, by looking at all the parts, we can see that the mindset in the batter's box of Major League Baseball players has changed over the years, and can explain the recent increase in homeruns within the league.

PD: Phoenix woman stabs Uber car used by boyfriend to escape assault
by Joe EneaPHOENIX — A woman allegedly chased her boyfriend and stabbed the Uber car he used to escape from her.
Phoenix police report that in the early morning hours of December 3, Monique Shanice Robinson, 25, chased her boyfriend out of their apartment with a butcher knife.
She reportedly chased him into the parking lot, where he was attempting to enter an Uber car to leave. Robinson allegedly chased him around the car, trying to stab him. When the victim got inside the Uber car, Robinson stabbed the car several times, according to police.
Police found Robinson at the apartment complex near 32nd Street and Thomas Road, with the knife still in her possession. Police say neither her boyfriend nor the Uber driver were injured.
She has been charged with aggravated assault and criminal damage.

Relatively light Takanoyama paid his dues in lower ranks
by John GunningAbout five years ago a sumo video went viral online and was widely shared on websites dedicated to other fighting sports.
The video itself was a low resolution (360p) poorly-edited effort with ill-fitting music, featuring a rikishi that spent only five tournaments in the top division and never went past the rank of No. 12 maegashira.
What grabbed the attention of viewers, though, was the muscular, ripped and very un-sumolike physique of the wrestler in question, as well as the high level of technical ability he displayed throughout the eight-minute clip.
The rikishi was Takanoyama.
Hailing from the Czech Republic, Takanoyama was well known to sumo fans as he spent a full decade in the lower divisions toiling away before finally making it to the paid ranks.
The Prague native started well in sumo and progressed up through the divisions at a reasonable pace initially. But once he hit the third-highest division (makushita), a lack of weight really hurt him.
A member of the Naruto stable along with future yokozuna Kisenosato and ozeki Takayasu, Takanoyama (real name Pavel Bojar) had no lack of decent training partners but found gaining weight extremely difficult.
Even at his heaviest, he barely broke triple figures and he spent most of his career fighting at around 90 to 95 kg. At 187 cm tall, that gave him an almost CrossFit-like physique.
Although he never managed a winning record in makuuchi, Takanoyama had some notable successes and even managed a 3-1 all-time head-to-head record against future title winner Tamawashi.
In 2005, he pulled off a win with the ultra-rare mitokorozeme technique — a move that was seen in the top division this tournament for the first time in 26 years.
Takanoyama was extremely dedicated and didn’t return to his home country once during his first 10 years in Japan, waiting until he had achieved promotion to the salaried divisions.

ActionCommand
This gem is currently in an experimentation phase, and should not be used by others.
Installation
Add this line to your application's Gemfile:
gem 'action_command'
And then execute:
$ bundle
Or install it yourself as:
$ gem install action_command
Usage
action_command
is designed to help you centralize logic which
might otherwise end up in a controller or model, and easily invoke it from
a controller, a test, or a rake command. I encountered the idea in the book
Rails
4 Test Prescriptions, tried it and liked it.
HelloWorld
You can declare an action with inputs and outputs
class HelloWorldCommand < ActionCommand::Executable
# You need to declare an attr_accessor for each named parameter
attr_accessor :name
# You can optional describe the input and output of the command,
# the text is used to provide help if you create a rake version of the command.
def self.describe_io
# the text in here is only
return ActionCommand.describe_io(self, 'Say hello to someone') do |io|
io.input(:name, 'Name of person to say hello to')
io.output(:greeting, 'Greeting for the person')
end
end
protected
# Override the execute internal method to provide logic for your action, and
# assign results to the result. You can also use methods like result.fail or
# result.info.
def execute_internal(result)
result[:greeting] = "Hello #{@name}"
end
end
HelloWorld: Execute from Rails
You can execute it from rails:
result = ActionCommand.execute_rails(HelloWorldCommand, { name: 'Chris' })
HelloWorld: Execute from Rake
When building a system, I find it useful to be able to easily run my actions from the command-line as well. In rails, you can create a lib/tasks/my_task.rake, and configure your actions as task with one line:
namespace :my_namespace do
# use [:environment] as the last parameter if you want to do things that require
# rails startup in your command, like connecting to your database.
ActionCommand.install_rake(self, :hello_world, HelloWorldCommand, [])
end
You can always invoke your rake task with [help] to see help on the input and output of the action. Then
rake my_namespace:hello_world[help]
will produce:
HelloWorldCommand: Say hello to someone
Input:
name: Name of person to say hello to
no_output: If true, intentionally produces no output (optional)
Output:
greeting: Greeting for the person
and
rake my_namespace:hello_world[chris]
will produce:
greeting: Hello chris
HelloWorld: Execute from rspec/etc
Or, you can execute it from a testing framework.
it 'says hello world' do
result = ActionCommand.execute_test(self, HelloWorldCommand, name: 'Chris')
expect(result).to be_ok
expect(result[:greeting]).to eq('Hello Chris')
end
If your command does a lot, you might like to do some internal verifications during the testing process to aid debugging. Inside a command's execute_internal method, you can use a block like this:
def execute_internal(result)
# ... do some logic
# t is the parameter you passed as the first argument to execute_test.
# so, if you are using rspec, this code block will only be executed when you are
# running in a testing context.
testing do |t|
t.expect(my_val).to t.eq(10)
end
end
Child Actions
Actions can execute their own child actions. Within an action's execute_internal method you should call additional actions via:
def execute_internal
@names.each_with_index do |name, i|
# the i parameter will cause the result of the child command to be nested
# in the result under that value. For example, here I would expect
# result[i][:greeting] to contain the greeting for each subcommand after
# execution.
ActionCommand.execute_child(self, HelloWorldCommand, result, i, name: name)
end
end
Error Handling and Logging
Error Handling
Within a command, you can generically fail with an error message, or fail with a particular custom error code
def execute_internal(result)
# fail generically
result.failed("Something bad happened")
my_custom_error = 10
result.failed_with_code("Something bad happened", my_custom_error)
end
You can check for errors in the result:
result = ActionCommand.execute_rails...
return unless result.ok? # generic failure
switch(result.result_code)
when ActionCommand::RESULT_CODE_OK
...
when my_custom_error
...
end
Logging
You can turn on logging either globally, or for specific command executions:
# turn it on globally
ActionCommand.logger = your_logger
# turn it on only for this command
params = {
logger: your_logger,
# your other parameters
}
ActionCommand.execute_rails(YourCommand, params)
When logging is on, the logger will receive single-line JSON messages at the info level for all command inputs and outputs. All child commands under a parent will automatically be tagged with a serial number for correlation. The result looks like this:
I, [2016-03-07T14:31:53.292843 #47956] INFO -- : {"sequence":"ade3605e40a4d5bf724c5f3d8e43420b","cmd":"CreateUserAction","depth":0,"kind":"command_input","msg":{"name":"Chris","email":"test@test.com","age":41}}

You can also optionally add your own entries to the log by calling
result.debug
, result.info
, or
result.failed
. You can pass these calls a string or a hash.
You can use the included LogParser to parse this log if you like, or you can use the included PrettyPrintLogAction to print the log in a nested plain text format, like:
HelloWorldCommand (8d315fe58dab39cb4f23a9f4ef366c8b)
input:
name: Chris
Hello Chris
output:
greeting: Hello Chris
ActiveRecord Transactions
You can wrap your command contents in a transaction by subclassing
ActionCommand::ExecutableTransaction
. You must explicitly
require action_command/executable_transaction
to avoid a
default dependency on ActiveRecord.
If you call result.failed
within a transaction, your
transaction will automatically be rolled back.
Utilities
It is often useful to allow a single parameter to be either an integer object id, an instance of the object itself, or a string used to lookup the object (used in command-line rake tasks). You can do this using
def execute_internal(result)
user = ActionCommand::Utils.find_object(User, @user_id) { |p| User.find_by_email(p) }
end
This will user User.find if passed an Integer, will return a user object, or will yield to the lookup otherwise.
Development
After checking out the repo, run bin/setup
to install
dependencies. Then, run rake spec
to run the tests. You can
also run bin/console
for an interactive prompt that will allow
you to experiment.
To install this gem onto your local machine, run bundle exec rake
install
. To release a new version, update the version number in
version.rb
, and then run bundle exec rake
release
, which will create a git tag for the version, push git
commits and tags, and push the .gem
file to rubygems.org.
