I like your idea of using "'<" with visual mappings. And regarding the
fact the backward-search jumps to the current PH instead of the previous
one is not completly illogical. I will eventually simplify my code to
adopt your way.

That's odd. Things have changed since the 3rd january version and the
1.24. Now, it is all right.

I see. Thanks.

I've seen his function just after I've written an equivalent one. Now,
I'd curious to have some input from people using encodings other that
latin1 or utf-8.

FTE (the plugin) serves a different purpose ; it has nothing to do with
jumping.

I see multi-line PH as an helper to the end-user who has just inserted a
template (from a file or from IMAP(), or ...). If the text is really
long and explain many things, I'm not sure PHs are the best things to
use. I see them more as markers where we will jump to and we will
eventually replace by some other text.


FTE permit to insert lines like (don't remember the exact format):

FTE: -------------------- begin -------------------
FTE: some introduction to the template that has been inserted
FTE: this comment may be very, very long.
FTE:
FTE: Next: the name of the environment
FTE:a:    %%%(environment name ; this is a PH)
FTE:b[ ]: Do you wish to center it ?
FTE:
    \begin{@a}
FTE: IF(@b, \begin{center})
       <+insert your code here+>
FTE: IF(@b, \end{center})
    \end{@a}
    <++>
FTE: some last comments
FTE: -------------------- end -------------------

Then, we can assign some value to @a and @b (by replacing the %%%()
placeholders), interpret the corresponding code (with <F6> for
instance). The result displayed could be:
    \begin{itemize}
       .... cursor here ....
    \end{itemize}
    <++>

I see his plugin as a multipasses templates plugin. One interresting use
is to insert the signature of some functions and an excerpt of their
man.


A solution made of PHs only would have contain a several lines-long PH
introducing the template. IMHO, this is a mis-use of PHs.

> Also, latex-suite does support templates in custommacros.vim
... and in templates.vim

But so far, I'm not sure it is as evolved as FTE or my unofficial
version of µTemplate.
