[Texmacs-dev] [LP mode] Should we have an source import command?

[David MENTRE]

Hello Felix,

I've started looking at how I could implement the "Import source..."
command for the literate programming mode. It appears that it is much
less obvious than I thought initially, especially because the comment
style varies from one project to another.

Taking some examples in TeXmacs sources:

 * TeXmacs/progs/kernel/gui/menu-define.scm:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;; Preparation of menu entries
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

(define (menu-format-error where which)


 * src/Classes/Abstract/observer.cpp:

/******************************************************************************
* Debugging facilities
******************************************************************************/

extern tree the_et;


 * another example:

./src/Data/Drd/tag_info.hpp:17:/******************************************************************************
./src/Data/Drd/tag_info.hpp:18:* The parent_info class contains outer 
information about tags
./src/Data/Drd/tag_info.hpp:19:*
./src/Data/Drd/tag_info.hpp:20:* -  The arity fields together with the 
child_mode determine the possible
./src/Data/Drd/tag_info.hpp:21:*    arities and how to convert logical indices 
of children to


It would need quite some heuristics to make an import mechanism that
works across all languages and commenting habits.

I'm wondering if it wouldn't be much more simple and efficient to only
allow regular opening, in that case the whole source file would appear
as a code block, and let the user "clean-up" the file with a few menu
items:

 - merge two code blocks;

 - split a code block (at mouse or cursor point);

 - remove one or more character at the beginning or end of each line
   (much like rectangles in Emacs);

 - transform a code block into text block and vice-versa.


What do you think of it?

Best wishes,
d.
