save buffer variables

[Joerg Sommer <joerg@xxxxxxxxxxxx>]

Hi,

is it possible to save blocal variables in the file? Sometimes blocal
vars holds values needed across a session e.g. the output type of a latex
file (pdf, dvi, ps). Can Jed save this variables automaticly?

Currently I use the following _jed_save_buffer_before_hooks hook:

private define save_buf_before_hook(filename)
{
   variable buf = latex_external->find_buf_of_file(filename);
   
   if (buf == NULL)
     buf = whatbuf();
   
   setbuf(buf);
   push_spot();
   eob();
   
   variable old_buf_flags;
   (,,,old_buf_flags) = getbuf_info();
   setbuf_info( getbuf_info() & ~0x20 );
   
   % the buf should end with a newline
   !if(bolp()) insert_char('\n');

   % Fix me!
   while ( andelse {up(1)} {bol(), looking_at_char('%')} ) {
      skip_chars("% ");
      if ( looking_at("LaTeX") ) {
	 bol();
	 push_mark();
	 eol();
	 ()=right(1);
	 del_region();
      }
   }
%   ()=down(1);
%   !if (eobp()) { eol(); insert_char('\n'); }
   eob();
   
   foreach ( ["LaTeX_master_file", "LaTeX_output_format"] ) {
      variable name = ();
      if ( latex_external->exists_master_file_var(name) )
	insert("% "+name+": "+latex_external->get_master_file_var(name)+"\n");
   }
   setbuf_info( getbuf_info() | (old_buf_flags&0x20) );
   pop_spot();
}

This code is very simple to use for any other mode and I think there
similar applicabilities. Hence it makes sense to put this code in jed and
make blocal vars "exportable".

Bye, Joerg.
