Wrap text option looses highlighting about nb_pdf_template HOT 16 CLOSED

Hooray! Moving from TeX Live 2015 to 2018 did the trick! I used the official directions (https://www.tug.org/texlive/quickinstall.html), not random ppa's you can find on SO. Closing this and opening a new issue for the print output.

from nb_pdf_template.

Have you installed with the minted option? If you haven't then it should be identical to the old version. If you have can you send me the a conversion done with --to latex. I'll need the latex to diagnose.

from nb_pdf_template.

Raw pyout will automatically wrap. (So, text displayed with an "Out []" prompt). Printing from a print statement will reply on the newline characters already in the string (which can easily be added there, but not so easily in raw pyout). I can look into text wrapping other text outputs.

I can't replicate this issue locally. What OS are you using? Does doing:

python -m nb_pdf_template.install

fix it? The minted option is still experimental (for reasons exactly like this!)

from nb_pdf_template.

I'm on Ubuntu 16.04. I installed with the --minted option. I tied to revert to the non-minted version with python -m nb_pdf_template.install, but ended up getting latex errors about shell escape. I then tried going back to the regular nbconvert template, and got the same error. Ultimately I reinstalled nbconvert with pip to get back to normal.

I ended up finding this to solve the problem I was really after (wrapping). http://www.markus-beuckelmann.de/blog/customizing-nbconvert-pdf.html Maybe It'll help you.

The problem with that solution is that if code wraps, then it may not be highlighted properly. I'd have liked to see what some of those errors were.

from nb_pdf_template.

So I just did this again on a different computer, with Ubuntu 16.04 as well. Same problem with the minted version.

Then, going back to python -m nb_pdf_template.install renders the pdf as expected, with overflow. I'm not sure what my issue was before.

The problem with that solution is that if code wraps, then it may not be highlighted properly.

Yes. You're right. Using that template I linked to, the wrapped line isn't exactly colored correctly.

from nb_pdf_template.

I had to remove the images to compile since I didn't have those, but it compiled fine for me.

Maybe try settings the latex command to:

c.PDFExporter.latex_command = ['xelatex', '--8bit', '--shell-escape', '{filename}']

Maybe the extra dashes are needed on your system.

Try finding a latex command like:

XeLaTeX --shell-escape -8bit hw1.tex

If we can find the command to compile it, then it should work. (adding the shell-escape to nbconvert's latex command should do nothing when using the non-minted option)

from nb_pdf_template.

It's compiling. But the output isn't correct. Look at the first post with the image.

If I check xelatex --help, it shows single dash arguments: -shell-escape -8bit

You can try droping the -8bit (it's only needed for processing tab characters).
Also, is pygmentize in your path? To find the version: pygmentize -V. I think the latex minted package may be tokenizing properly, but then failing to call pygmentize.

$ pygmentize -V

I upgraded to 2.2.0. Same thing as original post. I removed -8bit from the command list (i.e [NbConvertApp] Running xelatex 3 times: ['xelatex', '-shell-escape', 'notebook.tex'] ) Same result. There is nothing telling me what is going on. Here is output I'm seeing:

I set up a ubuntu virtual machine last week, so I'll try to test it out, but it'll have to wait (maybe until the weekend). You could try updating LaTeX and minted if that's an option.

For now I'll have to suggest going back to the non-minted version, and keeping lines to a max length of 94 characters (for classicm.tplx, 86 for classic.tplx) (latex uses a monospaced font so this will always work). Which PEP8 recommends 80 characters anyway.

For the printing of stuff. You can convert to a string with str(…) manually first and add newlines \n as needed. I'll try to get a fix for that this weekend though.

from nb_pdf_template.

OK. I'll look into that. I'm not sure if this will help, but here is the complete output from nbconvert: https://pastebin.com/GDCXRY1e and tex log hw1.out.txt

Yeah I know 80 is PEP8. The whole point of jupyter for me is to act as a quick scratch pad. The code isn't hardened or really meant for others to read. For real projects I use yapf for linting.

I'm going to get texlive 2018 installed (currently using the 2015 version that you can install with apt) and see how that goes.

from nb_pdf_template.

I'll add something to the readme about using newer versions of latex for the minted option.
