The variables TeX-fold-macro-spec-list, TeX-fold-env-spec-list, and
TeX-fold-math-spec-list apply to any AUCTeX mode. If you want to make
settings which are only applied to LaTeX mode, you can use the
mode-specific variables LaTeX-fold-macro-spec-list,
LaTeX-fold-env-spec-list, and LaTeX-fold-math-spec-list
So users should deduce from this that there is also
`Texinfo-fold-env-spec-list', which is, optimistic. But before fixing
the manual, I wonder what the idea behind the implementation is: The
variables are not custom variables, so in order to make
`Texinfo-fold-env-spec-list' for example to work, one has to setq it.
I'm CC'ing Ralf who wrote the code, maybe he can remember the idea
behind it.
@Ralf: The code was introduced with commit ae2fcc1685. Do you still
remember the idea behind the part:
+ (let ((symbol (intern (format "%s-fold-%s-spec-list"
+ (TeX-mode-prefix) elt))))
+ (when (boundp symbol)
+ (symbol-value symbol)))))))
If I get it right, things like `Texinfo-fold-env-spec-list' should be
custom variables; otherwise I'd use `intern-soft' above and slightly
adjust the test.
This helps, thanks. However, there are some issues.
* I tried to set
```
(setq Texinfo-fold-env-spec-list
'(("[macro]" ("macro"))
...
```
This converts
```
@macro foo {bar, baz}
...
@end macro
```
into
```
[macro]
```
which is not very helpful. Is there a way to get
```
[macro foo]
```
instead?
Does something like
(setq Texinfo-fold-env-spec-list
'((1 ("macro"))
...
helps (which I didn't test)?
* There is no example for
If the first element is a function symbol, the function will be
called with all mandatory arguments of the macro and the result of
the function call will be used as a replacement for the macro.
Additionally, this documentation paragraph confuses me: Are the
'mandatory arguments' passed as plain strings arguments? Or a list
of strings? Or something else?
I'd like to pass this question to Ralf as well; otherwise I have to read
and understand the code (which I've never used for any mode in my life).
* `Texinfo-fold-type-list` is missing – or not documented.
* In combination with the last item, it seems that there are no
folding defaults for Texinfo mode. Maybe it makes sense to have the
same default as with other TeX modes, i.e., folding macros and
environments.
See above. I think we can change/expand this once we have a course of
action, i.e., introduce a custom variable `Texinfo-fold-type-list' and
preset it with whatever you think is appropriate.
Best, Arash
