[TxMt] Re: defining scope for spelling

[David Howden]

Hey!

I do remember saying something like that, and then hoping that someone
else would experiment with it!  Unfortunately I'm rather too busy with
other problems at the moment, but I can quickly give a more detailed
explanation of how I think this could work, or at least where I got
the idea from!

In .tm_properties files you can set things like:

[ scope.name ]
spellChecking = true
spellingLanguage = 'en_GB'

So I was thinking that you could inject a grammar (or just modify the
grammar that you are interested in, i.e. LaTeX), with a definition for
a new scope, say

meta.lang.fr

and then in .tm_properties you could put

[ meta.lang.fr ]
spellChecking = true
spellingLanguage = 'fr'

I think the hardest part would be actually writing the grammar stuff.
A quick google springs up a semi-useful link that would get you
started:

http://manual.macromates.com/en/language_grammars
http://developmentality.wordpress.com/2011/02/08/textmate-introduction-to-language-grammars/

And there's the TM book (Pragmatic Textmate Power Editing) which has a
whole chapter on creating grammars.

For information about the new grammar injection stuff, again give it a
google - there is some chatter here somewhere (I remember it going
on!), and there is definitely a whitespace bundle which uses it to
show bad whitespace
(http://mads379.github.com/posts/whitespace-tmbundle).

EDIT: Decided to just try it myself. The grammar injection works fine,
though it can mess up the highlighting. Sadly the spelling checker
doesn't seem to work on a per-scope basis (maybe this is something on
Allan's todo list?).  As I wrote the instructions as I was doing it,
I've included them here just incase this gets fixed in the future (or
someone can spot the silly thing I've done which makes this not work
:-)).

In Bundle Editor, open the Latex Bundle and press Cmd+N to get the
"Create new Item" sheet.
Choose "Grammar"

Set an approprate name (mine is "Language Block").  Remove all other
settings (for the moment!), and set Injection Selector to "*".  Set
the grammar to be:

{	patterns = (
		{	begin = '\blang\=fr\b';
			end = '\bendlang\=fr\b';
			name = 'meta.lang.fr';
		},
	);
}

(check that above links for how to write grammars).

Then restart TM2 (from a few tests just now, this was necessary for it
to appear!).

Now, in a latex document:

lang=fr
Bonjour!
endlang=fr

(we need to change the lang, endlang syntax to be ignored by latex,
but that is a job for later).

Place your cursor before the letter B and hit Ctrl+Shift+P (to show
you the scope).  It will show meta.lang.fr in the list that appears.
The language injection works!

Now put the properties into a relevant .tm_properties file (as above),
and it should work fine (though not at the moment :-/).

Hope this is helpful! At least you don't have to bother until this works :-).

David.

I don't know regex (only very minimally) and where to define such scope. Thanks for pointers.
