*g:vimtex_fold_commands*
|

*g:vimtex_fold_commands_default*
|
||||
Use this option to disable/enable folding of commands. The option is
|
||||
a dictionary of key-value pairs, where the key is a regex in very magic mode
|
||||
(see |\v|) that matches the desired command name(s), and the value is the
|
||||
variant of command folding. There are three variants allowed (see below for
|
||||
a few examples that may be clarifying):
|
||||
|
||||
\hypersetup{
|
||||
option 1,
|
||||
...,
|
||||
option n
|
||||
}
|
||||
`single` Useful for commands with a single long argument.
|
||||
`single_opt` Useful for commands that open with a single long optional
|
||||
argument, then a short "real" argument.
|
||||
`multi` Useful for commands that start with a short regular argument
|
||||
and continue with long optional and/or regular arguments. In
|
||||
order for the folding to work as expected, this style depends
|
||||
on the indentation to be correct. See the example below for
|
||||
how to properly format the folded regions.
|
||||
|
||||
The option combines the contents of |g:vimtex_fold_commands| and
|
||||
|g:vimtex_fold_commands_default|. Entries in the former will have higher
|
||||
priority than entries in the latter. This way, it is easy to add custom
|
||||
entries without disturbing the defaults. For those who want to ignore the
|
||||
defaults, one may simple set |g:vimtex_fold_commands_default| to an empty
|
||||
dictionary.
