Support for autocompletion of commands defined through \DeclarePairedDelimiter and other "command-defining" commands like \NewDocumentCommand

[rionda]

The commands that are locally defined through \newcommand show up in the autocomplete tab from, e.g., YouCompleteMe, I assume through some magic in vimtex =).

It would be nice to also have the commands that are defined through \DeclarePairedDelimiter (I believe it is from mathtools) and \DeclareDocumentCommand and \NewDocumentCommand (from xparse) added to the list for autocompletion.

Thanks!

That might be possible, but it would be very helpful with more info. Especially, some good examples and reference to the relevant commands would be in order.

For example, I almost always declare the following for absolute values or set cardinalities:

\DeclarePairedDelimiter\abs{\lvert}{\rvert}

and use it as \abs{S} to get |S|. It is described in section 3.6 of the mathtools guide. Essentially, I would like the autocomplete to suggest \abs when I start typing \ab or similar.

\NewDocumentCommand and \DeclareDocumentCommand are a little more convoluted because they are extremely flexible, but all we care about is the name of the command that is declared.
Here is an example

\DeclareDocumentCommand\domain{mo}{% {method}[graph]
  \symcal{D}_{#1%
    \IfNoValueTF{#2}{}{,#2}%
  }%
}

which I can use as \domain{B} or \domain{B}[A]. They are described in the xparse documentation.

Hope this helps, and thanks for considering it.

Please test now. The xparse command was already supported, actually, but only with \DelcareDocumentCommand{...} syntax. I think it should work more generally now.

Seem to work! Thank you!

Glad to hear it! :)
