JavaScript and TypeScript syntax highlighting

[dubst3pp4]

The Shell session is also crashing… seems that only the Scheme session is able to run. I will try @jeroen suggestion (the generic tar.gz) today! Thanks for your support

[jeroen]

I just had a look at the highlighting already in TeXmacs and there is in fact a JavaScript highlighter there as well. It just doesn’t seem to be very well accessible from the menus.

You can insert it either by doing \javascript-code followed by the Enter key, or you can insert a code block for another language (e.g. “Fortran code”) and then change the language to JavaScript from the toolbar.

Oh wow, yes, this is the result that I was looking for! And it looks even okay with added type annotations (TypeScript).

There is still the issue of showing line numbers, for which there are two solutions none of which I have tried myself

How to add line numbering?

Actually it could be implemented using \datoms (see the manual). I’ve gave a try but is not perfect, I think is a bit fragile, anyway… it is a 10 min attempt. There are some problems with section numbers. <TeXmacs|1.99.15> <style|generic> <\body> <\hide-preamble> <new-counter|line-nr> <assign|line-nr-shift|-1em> <assign|number-line|<macro|<inc-line-nr><the-line-nr>>> <assign|decorate-line|<macro|body|<resize|<shift|<tiny|<number-line>>|<line-nr-shift>|>|0em||0em|><arg|body>>>…

[jeroen]

For code blocks you could also use \numbered

Today I installed the generic package of TeXmacs and everything works now! Thanks a lot for your support! TeXmacs is a great software

can anyone help me to get it working
I get “Busy…” all the time

[mgubi]

Can you be more specific? What is the operation that you are performing? I guess there should be some problem running Python maybe? We also need to know the OS and the version of TeXmacs.

[jeroen]

You could also try running a Python session, to see if TeXmacs can find your Python executable.

From there, try “import pygments”. It could be that TeXmacs uses a different Python than the one for which you have installed Pygments.

But some more details are definitely necessary.

[dubst3pp4]

I had the same problem and was able to avoid it by installing the generic TeXmacs package, see my answer above.

[codeLover]

thanks for reply!

here some informations:

• OS: macOS
• TexMacs version: 2.1.1

I can use a python session in TexMacs (Executable > Python)
there I can run a "print(“hello world”), but when I try to execute
“import pygments”, it is telling me that there is no module called “import pygments”

but pygements is already installed:
“Requirement already satisfied: pygments in /opt/homebrew/lib/python3.9/site-packages (2.11.2)”

I installed TexMacs with brew and by downloading the dmg

where can I get the “generic package of TeXmacs” ?

hope that helps

[mgubi]

On Mac there are several versions of python installed usually. You would have to be sure that you installed pygments for the python system that got run by TeXmacs. Maybe TeXmacs picks up the system python while you installed pygments for the Homebrew’s python installation.

[codeLover]

here is what I have so far:

I created a python executable
(Insert > Fold > Executable > Python)

There I added this code:

import sys
print(sys.version)

output:

3.8.9 (default, Oct 26 2021, 07:25:54) 
[Clang 13.0.0 (clang-1300.0.29.30)]

On another python executable I did this:

import pip
pip.main(['install', 'pygments'])

output:

WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.

To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.
WARNING: The script pygmentize is installed in '/Users/peter/Library/Python/3.8/bin' which is not on PATH.

Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.

You should consider upgrading via the '/Library/Developer/CommandLineTools/usr/bin/python3 -m pip install --upgrade pip' command.

In the OS-Terminal I executed this:

python3 -m pip install --upgrade pip

Not sure what to do next

[jeroen]

Your output indicates indeed that TeXmacs is using a different version of Python (3.8) than what is used from the command line (3.9). You can check which one TeXmacs finds by doing (url-resolve-in-path (python-command)) in a Scheme session.

[codeLover]

in a Scheme Session I used this:

(url-resolve-in-path (python-command))

output:

Scheme]  (url-resolve-in-path (python-command))

<url /usr/bin/python3>

what can I do next?

[jeroen]

You can try to install pygments for the Python version that TeXmacs uses:

/usr/bin/python3 -m pip install pygments

[codeLover]

I installed pyenv and this solved my problem

there is another problem, and thats the line breaks
all of them are ignored

can anyone help out?

[jeroen]

I made some changes to the plugin recently, did you pull the most recent commits?

If yes, please share the input you inserted and I’ll have a look.

[codeLover]

@jeroen: thanks! works like a charm

this plugin must become part of TeXmacs by default!

Any news on this Python issue?
