The variables TeX-fold-macro-spec-list, TeX-fold-env-spec-list, and

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.
I don't tend to add riddles to manuals. ;-) I guess I only mentioned the
LaTeX-mode-specific variables because those are the only ones
implemented as custom variables. Why the other ones are not,
unfortunately I don't remember. It's not just the ones for Texinfo mode
but also for ConTeXt, docTeX and so on. Perhaps I didn't have enough
trust in the folding support for other modes than LaTeX. The latter is
the only one which received much testing and usage.
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.
As hinted at above, it could be that this was a way to let people in the
knowing test a feature that was still experimental. They could setq the
variables and assess the results whereas regular users would not
directly see them.
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)?
I just tested it and you just get an ellipsis (...) when a macro is
folded. Without looking at the code, it seems that it does not consider
the first thing behind @macro to be an argument. This could be a missing
feature. As mentioned above, Texinfo mode was not the focus of
development and usage, which is the likely reason for this.
* 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).
It's a list of strings, see `TeX-fold-hide-item'. Inside of ((functionp
spec)...) you can see the list `arg-list' being built and then used to
call the function behind `spec'.
