Hi,
I use sublime text 3 for latex. In the latex documents, I have some parts containing C++ code
(defined between \begin{lstlisting} and \end{lstlisting}).
How can I explain sublime text that between these two delimiters, it is C++ code ?
I mainly want to be able to use AstyleFormatter plugin on C++ code parts.
It seems that it is possible with tmLanguage but it is not clear for me.
Thanks in advance,
Mathieu
Can’t you just select the region of C++ code and choose SublimeAStyleFormatter: Format Current Selection from the command palette?
Yes it’s possible, but you will have to modify the latex syntax.
Sublime Text 3 doesn’t use tmLanguage anymore , but a .sublime-syntax format.
I don’t have time to give you a full response now, so I’ll just leave the doc: https://www.sublimetext.com/docs/3/syntax.html
I’ll come back with an example later.
Latex syntax has been re-written but not yet merged, compare:
I guess @randy3k could answer that question!
This is already a feature in the pull request @rppn referenced. You can see in a screenshot near the end of it showing that it works for Python code, for example. However, it needs more polishing, which is why it hasn’t been merged yet.
Hi,
Thanks a lot for all your answers.
However, I wonder whether changing the highlighting for the C code (even if it would be much appreciated)
would allow me to apply plugins for C code (like AstyleFormatter for instance) in a latex file.
Is that true? In this case, I can wait for the merge of the latex syntax or try to write a .sublime-syntax format as suggested by @gwenzek .
Otherwise, is there some tricks to manually specify that some parts of a file must be considered with other such as:
latex code %! begin of language C C code %! end of language C latex code
Mathieu
@315234 : the problem is that, without changing the syntax of the file (in the command palette, set syntax C), the plugin AstyleFormatter is not even available. Hence, each time I need to format a small example of C code, I need to change the syntax of the file to C, then apply the plugin and change back the syntax to latex.
If you choose to edit the Latex syntax, you can have a look at my Markdeep syntax.
In Markdeep you can insert code block with ~~~~ <language-name>, ended by ~~~~.
The important part of the syntax code is the
push:
- meta_content_scope: markup.raw.block.markdeep
- include: "scope:source.python"
with_prototype:
- match: '(?=(~{4,}|`{4,}))'
pop: true
The include allows to use another syntax, and the with_prototype allows to pop out of the syntax you included.
It’s important to use a look-ahead regex (with the (?=...)) allowing to pop until we are out of the python syntax.
To modify the current syntax file you can just install PackageResourceViewer and open the latex syntax afterwards search for python (which is supported) and add the C++ syntax similar.
Or you download the new latex syntax and move the LaTeX folder into your package directory.
Afterwards just add a comment to your document:
\begin{lstlisting} % C++
int foo = 5;
\end{lstlisting}
Hi,
Thanks for your answers.
I have downloaded the latex directory and put it in
~/.config/sublime-text-3/Packages
(I have first renamed the existing Latex directory).
However , it doesn-t work, C++ is not taken into account
(I tried java and python and it works for these languages).
Mathieu
You must download the LaTeX folder from the git branch latex. The current syntax only supports python and java, the new one will support many languages.
It works! In fact, the problem was that I renamed the old latex directory without moving from the package directory. Thus, I had two different “latex syntax” in ST3: one for the new and one for the old one.
Thanks a lot everybody.
Hi,
Everything is ok, except that I need to choose “set syntax latex” in the command palette for the C++ code part to be taken into account, each time I open my latex file. It seems that is it not initially considered.
Is that normal?
Mathieu
No, that is not normal. You could try to open the ST console ctrl+` and write view.settings().get("syntax") when the C++ is not available and when its available. I would assume you get different syntax files.
Hi,
You were right. Initially, the syntax file was LaTeX+.
After several attempts to modify the Latex+.sublime-syntax file,
I copy/past the Latex.sublime-syntax content into the Latex+.sublime-syntax
(I only change the name line 4).
Now, everything works.
Thanks a lot!!!
