I'm fine with using a template engine for the more involved cases

are rare enough). However, I'd prefer not adding a new dependency, but
just shipping a tiny single-module engine with Cython, e.g.
Templite or
pyratemp (just found them, never used them).
BTW, I don't think anybody is suggesting having an *external*
dependency
that users would need to go fetch themselves....that would be insane.
Sure. I also don't mind having a small engine in a package, but just
putting a single file in the source tree (and overwriting it with a new
version at need) would be a perfectly small and nonintrusive addition.
And
given that there really are engines of that size (one file, <500 lines),
it's not so unrealistic either.
That being said, if you can recommend Tempita (which IMHO qualifies as
"small enough"), I won't object to it.
... although, isn't it unfortunate that it uses "{{...}}" for template
code? How well readable is that when used in C code?
At least in emacs, pretty much any template syntax will mess up things
pretty badly, especially automatic indentation and so on.
What I do is using mmm-mode, so that everything within {{ and }} is
highlighted with python-mode, and the rest with c-mode. I'll share my
configuration later.
I'm merely stating why this has never been an issue for me, I'm NOT
suggesting everyone should use emacs (or that plain text editing isn't
convenient); you do have a point.
Keep in mind that a syntax must work well with utility code written in
Cython as well.
OTOH one *might* want to have
code.put_tempita(..) # or similar
in Python code, and in that case plain text readability is very important.
Of course, hacking Tempita to make it %[ ]% instead is a five minute job.
But I'm happy with any other engine that somebody have actually tried out
extensively.
Tempita has a syntax for comments - what about using the regular C and
Cython comments as template syntax delimiters? That way, you'd write
/*# some comment */
to get an actual comment in C code, and
/* for x in y */
for template code. For Cython code, we could use "##", or maybe "#<" and
">#". That should work pretty well with editors.
