Custom Command Highlighting in TeXstudio

Question

I have defined several macros in my LaTeX report. For instance, following is a macro I defined for writing bold letter H. I have several macros like this I use throughout my work.

\newcommand{\channel}{\ensuremath{\mathbf{H}}}

Whenever I use \channel, TeXstudio highlights it as red saying unknown-command. But it is indeed supported by the auto-completion feature. I want to stop TeXstudio from highlighting it as red (as it is annoying and affects readability). Is there any way to do this?

Update---

After seeing the comments, I realize I forgot to include a important thing. I always write these macros and package calls all inside a single file. Then I input this file in the LaTeX file I am writing. But now I guess I am asking a bit too much. I mean I require the software to recognize the macros which I have input from another file. Nevertheless I was wondering if there was any solution.

Answer 1

Normally, TeXstudio recognizes a \usepackage{…} in the main file and does load the auto-completion list (.cwl), but TeXstudio isn’t intelligent enough to recognize packages loaded in external files.

You could manually select the auto-completion lists for packages loaded in the external file, but then they are active in every document.

For custom commands I only see a solution with a custom .cwl file which, of course, has the same disadvantage (always active if not disabled).

Answer 2

I had the same problem, I found a way to solve it (I have TeXstudio installed on Ubuntu 16.04). In the "structure" panel (on the left of the editor), simply click on the name of the file you want to input.

Here is a MWE, with some snapshots to make it clear : I created a file def.tex just containing the line \newcommand{\channel}{\ensuremath{\mathbf{H}}} and a file testDoc.texcontaining the following lines: \documentclass{article}\input{def}\begin{document}\channel\end{document} As expected, \channel is highlighted in red as shown on this snapshot:

Now, if I click on the file def in the left panel called "structure" (this will simply open def.tex in the editor), and go back to testDoc.tex the red highlight disappears. Moreover, autocompletion now includes the suggestion for channel:
