How to get all required modules from node.js as a single text file or string?

I need to get all files from some require stack and this include all requires inside the required too.
Example:
file.js
require("./b");
require("./c");
//require("./d"); // this is a comment, need to prevent that
AST
[{
path: "absolute_dir/b.js",
name: "7saf7fs6asf7" // hash
},
...]
ouput (with the AST i can get all files by his name and put them in one single file, like a bundler)
require("7saf7fs6asf7");
require("sa8d78as8d7f");
I don't know how to do this in a modular logic. PLZ help me :)

How to use different syntax for same file extension on Sublime Text? (JS/JSX)

With Sublime Text, is it possible to use different syntax for a same file extension depending on the currently opened project ?
Example :
Project A : file.js contains classic Javascript
Project B : file.js contains JSX
How can I obtain JavaScript syntax for project A and Babel syntax for Project B?

Just for background (which you likely already know), Sublime Text applies a syntax via the extension of the file, and overriding that requires you to use View > Syntax > Open all with current extension as... from the menu. This creates a syntax specific override which appears in a specific file name and is thus not directly overrideable on a per project basis.
That said, it is possible to swap the syntax on your own (e.g. via the command palette) which opens the possibility of a plugin being able to do this for you. There may be an existing plugin that does this in PackageControl, but for reference purposes, here is an example based on something I'm using for a similar purpose.
The following assumes that you're using the Babel plugin to get your syntax highlighting, since you mention Babel. This would need to be modified if this is not the package you're using. This could also be modified to similarly do a swap for a different type of file if desired.
To use this, select Tools > Developer > New Plugin from the menu and replace the entire contents of the sample file with the code below, and then save it as a python file in the directory that Sublime suggests (which should be in Packages\User). I named mine js_syntax_swap.py, but the name doesn't matter as long as the extension is .py:
import sublime, sublime_plugin
# Standard Sublime JavaScript syntax file is:
# 'Packages/JavaScript/JavaScript.sublime-syntax'
#
# The Babel package syntax is:
# 'Packages/Babel/JavaScript (Babel).sublime-syntax'
class JavaScriptSyntaxSwap (sublime_plugin.EventListener):
def modify_syntax (self, view):
if view.window () == None:
return
swapSyntax = view.settings ().get ('using_babel_js', False)
curSyntax = view.settings ().get ('syntax')
variables = view.window ().extract_variables ()
extension = variables['file_extension']
if swapSyntax is True and extension == 'js' and "Babel" not in curSyntax:
view.set_syntax_file ('Packages/Babel/JavaScript (Babel).sublime-syntax')
def on_load (self, view):
self.modify_syntax (view)
def on_post_save (self, view):
self.modify_syntax (view)
With this in place, if you choose Project > Edit Project from the menu, you can include a using_babel_js setting to enable the plugin for JavaScript files in that project. An example might be:
{
"folders":
[
{
"path": "."
}
],
"settings":
{
"using_babel_js": true
}
}
What this is doing is checking every time you load or save a file to see if it should swap the syntax from the default to the Babel JSX syntax, which it does only for files with the extension .js that are not already using Babel as the syntax.

Arrays using commander

Hei guys!
I need help with the commander node.js library. I need create this CLI which accepts 3 flags, --input, --output and --pattern, like:
commander
.version('3.0.0')
.usage('[options] <file ...>')
.option('-i, --input', 'Array of files to be extracted')
.option('-o, --output', 'Output file name')
.option('-p, --pattern', 'Pattern name to be used in the extraction')
.parse(process.argv);
My problem is with the input flag. I need send several files, for that i need an array data type.
The problem is: I just can't figure it out how to make this:
node ./bin/extract -i ../files/*.PDF
become an array with all my files that are inside my files directory. I already try to run every sample in the documentation, and i didn't find the solution for my problem. Also, i searched in the issues and didn't find either... what is strange, maybe i am doing something wrong and you guys could help??
Thanks!

You can use Coercion to achieve it:
function scanDir(val) {
files = fs.readdirSync(val);
return files;
}
program
.version('0.0.1')
.option('-s, --scan [value]', '', scanDir)
.parse(process.argv);
console.log(' scan: %j', program.scan);
And call it like:
node app.js -s /foo

Django's support for translations in Javascript files

I read and followed the instructions in here, but can't seem to see the string in the javascript in the po file.
structure of my project is:
cb/
cb_app
cb
static_files
templates
First I copied these into my url.py:
js_info_dict = {
'packages': ('cb_app',),
}
urlpatterns = patterns('',
(r'^jsi18n/$', 'django.views.i18n.javascript_catalog', js_info_dict),
)
Then I added this script to my html:
<script type="text/javascript" src="{% url django.views.i18n.javascript_catalog %}"></script>
The actual script where I would like to get the translation, is as simple as that:
$(document).ready(function () {
$('#id_sales_item').chosen({no_results_text: gettext('No results match')});
});
...and is utilized in the same html.
So is there anything more I need to do?
All I did then was to run the line below both from cb/cb and from cb/cb_app.
django-admin.py makemessages -l en_GB
But still no sign of 'No results match' in either cb/cb/locale nor in cb/cb_app/locale
Any tips?

I have finally found the problem.
The documentation suggests creating the messages once from the Django project and once from Django app. That way you end up with two locale directory. And in neither of those would the javascript translations be picked up anyway. This is quite a mess.
The cleanest solution I have found is to go to settings.py and insert this line (see also my project hierarchy above):
LOCALE_PATHS = ( '/home/kave/projects/cb/locale',)
Then create a directory called locale in the project-root-directory (see the path above)
Don't forget applying the entries into url.py and html as well (see above).
Finally now that the local's are unified into one place, go to project-root-directory: /home/kave/projects/cb and run these two commands:
django-admin.py makemessages -l en_GB
django-admin.py makemessages -d djangojs -l en_GB
The first command get the translation texts from both project and app subfolders.
The second gets the javascript translation into a second po file.
Thats it.

Extracting Javascript gettext messages using Babel CLI extractor

It is stated here that Babel can extract gettext messages for Python and Javascript files.
Babel comes with a few builtin extractors: python (which extracts
messages from Python source files), javascript, and ignore (which
extracts nothing).
The command line extractor is documented here - but with no examples on usage.
Also in the same pointer above, there is some mention of a config file to be used with extraction, but not much expanded on.
When I run the basic command for the extractor on a dir with js files, I get only the .PO header generated but no messages.
$ pybabel extract /path/to/js-dir
# Translations template for PROJECT.
# Copyright (C) 2012 ORGANIZATION
# This file is distributed under the same license as the PROJECT project.
# FIRST AUTHOR <EMAIL#ADDRESS>, 2012.

$
Here is a sample segment from a js file I'm trying to extract messages for:
else if(data.status == "1"){
var follow_html = gettext('Follow');
object.attr("class", 'button follow');
object.html(follow_html);
var fav = getFavoriteNumber();
fav.removeClass("my-favorite-number");
if(data.count === 0){
data.count = '';
fav.text('');
}else{
var fmts = ngettext('%s follower', '%s followers', data.count);
fav.text(interpolate(fmts, [data.count]));
}
}
I would appreciate it if someone can provide exact CLI options and config settings to make the extraction work, or a pointer to such.

Create a file (babel.cfg) with the following content:
[javascript:*.js]
encoding = utf-8
Then, do:
pybabel extract -F babel.cfg /path/to/js-dir
That should be enough for you to have some message strings.
BTW, you can consult the help for the extract command by doing:
pybabel extract --help

I had a similar issue and was able to get around it by disabling default keywords with babel.
pybabel extract -k __ -F babel.cfg --no-default-keywords /path/to/js-dir
You must specify at least one keyword in the command when you disable the defaults (-k [keyword]). I chose -k __ because "__" was a pattern I was looking for.
Just use this command and replace the "__" after -k with one from your babel.cfg file.
Edit: this allows you to use your own keywords rather than gettext()

You can create an object in as flask global and translate it with gettext
g.i18n = {
'Casa' : lazy_gettext('Home'),
'Auto' : lazy_gettext('Car'),
'Persona' : lazy_gettext('Person')
}
Then add it as a variable
<script>
var i18n = {{ g.i18n | tojson }}
</script>
and use it in JS:
var labelTranslate = {
Casa: i18n.Casa,
Persona: i18n.Persona,
Auto: i18n.Auto
};

You can actually use gettext directly in Javascript.
See: jsgettext. It allows you to use the standard *gettext functions, including the one using contexts and/or plural forms.
It can read PO/MO files or you can import custom made JSON files instead.
See this file of this project for a complete example.
