\includegraphics filename autocomplete does not work with optional arguments (emacs)

[WannabeSmith]

First, thanks for this awesome project!

OS/editor details:

OS: macOS Monterey
Editor: Emacs 27.2
LaTeX: TeX Live 2021 (installed mactex via homebrew)

Description of the issue:

When using the \includegraphics macro, if I write

\includegraphics{}

and begin typing a filename (e.g. an image) within the curly brackets, I successfully see an autocompleted list of filenames through which I can scroll, select, and so on. This is the desired behaviour.

However, if I add optional arguments, such as

\includegraphics[width=\textwidth]{}

and begin typing the same filename, no such autocompleted list appears. It would be great if the list of filenames were available regardless of whether optional arguments have been added or not.

It would be great if the list of filenames were available regardless of whether optional arguments have been added or not.

This should normally work so it appears to be a bug. On my machine, I cannot reproduce the issue with the example you provided:

Is there something around the statement, which could mess with the parser like unbalanced braces? In this case, a full example file could help.
Also, what texlab version are you using?

[WannabeSmith]

I am using texlab version 3.3.2.

You're absolutely right, the example I provided works fine. My apologies. It fails when I use the option [width=0.5\textwidth] (note the 0.5).

Here's an example. Note that the first two autocompletes work fine, while the third does not.

Thanks, I am able to reproduce the issue, now. 0edafcf fixes the error in the parser.

Released with texlab 4.0.0.
