hotkey for comment/uncomment lines/blocks

[swizzle]

PhpStorm has the hotkey Ctrl + / which comments the current line or the selected block.
Of course every language has its own comment system but Scratch should be smart enough to put the right comment symbols
around the line/block.

PS: For commenting a line the cursor just needs to be in the current line itself. The line doesn't have to be selected.

Little hint: gtksourceview knows what tokens the language uses for line and block comments, if the .lang file specifies this, ofc.

See: <metadata> on https://developer.gnome.org/gtksourceview/unstable/lang-reference.html
and http://valadoc.org/#!api=gtksourceview-3.0/Gtk.SourceLanguage.get_metadata

Haven't tried this, but it should work somewhat like this:

var line_comment_start = source_language.get_metadata ("line-comment-start"); // block-comment-start, block-comment-end

for C this would return "//", "/*", "*/" respectively.

Gedit already has a plugin that does this job. Couldn't it be ported to scratch?
Here's a blog entry describing the plugin: https://delightlylinux.wordpress.com/2015/05/22/code-comment-gedit-plugin/

The plugin code is here:
