Latex compilation not working after updating to Ver 1.15 3
Opened this issue · 11 comments
I downloaded the most recent version of a-Shell for iPad OS 18 today. However, since downloading it I can no longer compile Latex files on a-shell because the terminal window says "pdflatex: command not found" when I try to compile a tex file. The package list says that texlive is installed.
Can you let me know a fix for this as soon as possible? My workflow has come to a standstill.
Thanks,

I deleted the app > re-downloaded it > re-installed texlive > compiled a tex file I was trying to compile before. Compilation worked as usual with pdflatex filename.tex
I quit a-Shell. Upon re-opening the app and trying to compile the same document, a-shell again could not recognize the command pdflatex. So every time I am closing a-shell, it seems it is unable to reach whichever directory texlive is in.
Thanks for the report. I can reproduce the first issue. Your second message is very useful in that they give me a clue about what's happening. This has a very high priority obviously. I'll keep you posted.
Thanks a lot! For now I am making everything work by just keeping a-shell running in the background (i.e. not closing/quitting the app).
It affects both clang and pdflatex commands. It does not happen after reinstalling TeX, so it's something that happens at startup. The issue is likely in the updateCommands() function, which is called both at startup and when you install the TeX or LLVM packages. It must be failing early in that function, otherwise it would install the small pdflatex command that says "You must install texlive for pdflatex to work". Let me check if the issue also happens when running a-Shell through XCode.
I found the issue: it's related to how XCode 16 treats conversion to C pointers. The fix for updateCommands() is easy (don't check the arguments, just run the command), but the same issue also happens in changeDirectory(), and I need to fix that too.
When you fix the issue, I am assuming you will put a preliminary version on Testflight. I would appreciate if you could send me an invite to test the updated version of the app before the official version is released in the App Store. I absentmindedly closed a-shell recently and had to reinstall texlive for things to work.
It's a link-based TestFlight: https://testflight.apple.com/join/WUdKe3f4
For major issues like this one, I go straight to an AppStore release. I don't want to have people dealing with this for days (also, an AppStore release can be faster than a TestFlight release, I know it's weird).
Huh, I was wrong: the TestFlight version has been approved before the AppStore version. Enjoy testing.
Great. The issue is fixed on my end in the Testflight app version. Thanks very much for addressing it promptly.
Thank you for signaling it so quickly. And your two messages describing it practically narrowed the search to a single point in the code, which really helped in fixing it.
(It was an issue with how C pointers are handled in Swift, which changed in XCode 16, and I had to switch to XCode 16 in order to release a version for iOS 18)
