new language support (erlang)

[Todd Greenwood-Geer]

I'd like to add basic language support for erlang (.erl/.hrl) files.

I see this in the docs... but the web link on sourceforge is dead. Could someone point me at the appropriate docs?

How can I use Leo with unsupported languages?

Here is a posting which might be helpful: http://sourceforge.net/forum/message.php?msg_id=2300457 The @first directive is the key to output usable code in unsupported languages. For example, to use Leo with the Basic language, use the following:

@first $IFDEF LEOHEADER
@delims '
@c
$ENDIF

So this would enable a basic compiler to “jump” over the “true” LEO-header-lines. Like this:

$IFDEF LEOHEADER <-conditional compilation directive
#@+leo-ver=4 <-these lines not compiled
#@+node:@file QParser005.INC
#@@first
#@delims '
'@@c
$ENDIF <-... Until here!
<rest of derived code file ... >

This changes the comment symbol the apostrophe, making comments parseable by a BASIC (or other language.)

Here's the opening post of that thread courtesy of The Wayback Machine (http://web.archive.org/web/20081210195031/http://sourceforge.net/forum/message.php?msg_id=2300457). Unfortunately the 6 replies don't seem to have been captured. However it gives the date, time & subject so maybe someone else can use that to pull out more.

Have discoverd & started using LEO 2 days ago By: Nobody/Anonymous (nobody) - 2003-11-23 04:44

I really like the concept, literate prog, and i find it delivers.    I have easily made some code with it for some other languages and have found that the "@first" directive is the key to output useable code in unsupported languages.  ...as example, for a BASIC language compiler:   ->body of a "@file" header:  -----------------------------Snippet

@first $IFDEF LEOHEADER  @delims '  @c  $ENDIF

-----------------------------End of snippet  So this would enable a basic compiler to "jump" over the "true" LEO-header-lines; wich gives you:  -----------------------Derived file begins with:  $IFDEF LEOHEADER <-conditionnal compilation directive

#@+leo-ver=4 <-these lines not compiled  #@+node:@file QParser005.INC  #@@first  #@delims '   '@@c  $ENDIF <-... Until here!  <rest of derived code file ... >

-----------------------end of snippet  The thing it does is mostly changing the comment symbol to " ' " apostrophe... making comments parseable by a BASIC (or other language.)    The thing that I really like is the fact that LEO untangles my code if I change it externally, in an IDE or editor of some kind!     hope this helps, if you have any tricks to share for adding compatibility / productivity using LEO, please tell me!    --  bolt

It appears that erlang already has basic support.  See the helper functions of g.app.__init__:

    @file leoApp.py-->class LeoApp-->app.__init__

There are entries for erlang in g.app.language_delims_dict, g.app.language_extension_dict and g.app.extension_dict.
