[Issue] LaTeX doesn't work again

[l4v3nx]

• I have read the Usage and the Troubleshooting pages of the wiki
• I have made sure that both my config and system packages are up to date
• Linux distro: Arch Linux

  The issue

  ai answers don't convert tex source code to normal formulas

(i expected the same result as in the screenshot bg)

Click to expand

```plain -> % LaTeX --help ... a lot of docs ... Usage: LaTeX [OPTION…] Help Options: -h, --help Show help options --help-all Show all help options --help-gapplication Show GApplication options --help-gtk Show GTK Options Application Options: --display=DISPLAY X display to use ``` ```plain -> % command -v LaTeX /usr/local/bin/LaTeX ```

[end-4]

latex rendering is possible but not perfect it won't be detected inline like that. you gotta tell it to put in a code block with language set to tex or latex when you type this you should get a latex block

[l4v3nx]

I thought it should be working because here init message says answer should be formatted in latex if there's maths in answer https://github.com/end-4/dots-hyprland/blob/a10d45883ce8a447177cb5b6ac27762308f6ef29/.config/ags/services/gpt.js#L60

[end-4]

and that answer also follows the format i pointed out above

[l4v3nx]

there's huge error spaming (i guess more that 50 or even 100 such messages) when i tried to make ai put its output to latex code block

do you get a properly rendered latex block when you run the /test command

[l4v3nx]

no

Gio.IOErrorEnum: Error opening file “/home/old4ever/.cache/ags/media/latex/1717067353520.tex”: No such file or directory
Gio.IOErrorEnum: Error opening file “/home/old4ever/.cache/ags/media/latex/1717067353520-render.sh”: No such file or directory

Same Issue for me:

[H0mire]

Running Latex from the commandline and rendering tan(x) logs following error:

FILE: /home/janik/dots-hyprland/cache/MicroTeX/src/fonts/fonts.cpp, LINE: 188, FUNCTION: getChar, MSG: { char: t, font id: 2, path: res/fonts/base/cmmi10.ttf } FILE: /home/janik/dots-hyprland/cache/MicroTeX/src/platform/cairo/graphic_cairo.cpp, LINE: 47, FUNCTION: loadFont, MSG: Load font: res/fonts/base/cmmi10.ttf, count: 2045967900 Null pattern FILE: /home/janik/dots-hyprland/cache/MicroTeX/src/platform/cairo/graphic_cairo.cpp, LINE: 54, FUNCTION: loadFont, MSG: Load res/fonts/base/cmmi10.ttf failed fish: Job 1, 'LaTeX' terminated by signal SIGSEGV (Address boundary error)

And why does it use dots-hyprland as a path. Is LaTeX specifically made for your dots?

[l4v3nx]

@H0mire LaTeX binary didn't move to /usr/local/bin at the installation (or didn't get built at all)

[H0mire]

@l4v3nx "which LaTeX" prints following: /usr/local/bin/LaTeX And I checked visually if it exists with Nautilus File Manager. Or what do you mean?

[l4v3nx]

@H0mire where did you get this log from? ags or journalctl?

[H0mire]

@l4v3nx I ran LaTeX from terminal and crashed after pressing render button, so i checked logging in the fish terminal window where the errors as provided were printed.

[end-4]

can confirm that gui crashes again though the sidebar works for me

[l4v3nx]

@H0mire yea, same issue

And why does it use dots-hyprland as a path. Is LaTeX specifically made for your dots?

we build microtex inside repo's folder and its source code remains there

[end-4]

oh i remember why that doesn't work that now that thing hard codes the font path relative to the workdir. the generated script to render stuff cds to the binary's folder to make sure font file detection works

[H0mire]

@l4v3nx Yeah i just figured out it is MicroTex. I guess its not like that the source code remains there, but more like that MicroText has the the original paths encoded in its binary.

[end-4]

@l4v3nx can you show what's in your ~/.cache/ags/media/latex folder after runnning that /test command?

[l4v3nx]

there's not even latex folder created

-> % ls .cache/ags/media/
1b3333efde4c64e0c80231cd483db0500f40840f
1b3333efde4c64e0c80231cd483db0500f40840f_colorscheme.css
1b3333efde4c64e0c80231cd483db0500f40840f_colorscheme.css.map
waifus

[H0mire]

there's not even latex folder created

Same here

[l4v3nx]

oh i remember why that doesn't work that now that thing hard codes the font path relative to the workdir. the generated script to render stuff cds to the binary's folder to make sure font file detection works

didn't install script copy res/ folder to /usr/local/bin/? and here

https://github.com/end-4/dots-hyprland/blob/a94172d9cd860113926e2c6fd7375c547564dc76/.config/ags/modules/sideleft/apis/ai_chatmessage.js#L105

binary would use res/ folder as the script moves to directory where LaTeX is (/usr/local/bin). i guess it should be working

[end-4]

yeah i mean it won't work if you just run LaTeX in terminal without cd ing there first

[H0mire]

After manually creating a latex folder in media following files are avaliable: But latex is still not correctly visualized And there is no error in the logs of ags

[l4v3nx]

some more info (inside /usr/local/bin/):

yay -S MicroTex and creating latex folder in media manually fixed the issue

yea, it works. btw, @end-4 you can delete /usr/local/bin/res and remove this line https://github.com/end-4/dots-hyprland/blob/a94172d9cd860113926e2c6fd7375c547564dc76/scriptdata/installers#L102

[H0mire]

why installing MicroTex through a function anyway? And there must be something that ensures the latex path in media/latex

[l4v3nx]

idk either, font paths are different than hardcoded ones (yay -Ql microtex-git)

[end-4]

why installing MicroTex through a function anyway?

there wasn't that package on the aur (first submitted march) when i started using microtex (february)

[l4v3nx]

https://github.com/end-4/dots-hyprland/blob/a94172d9cd860113926e2c6fd7375c547564dc76/.config/ags/modules/sideleft/apis/ai_chatmessage.js#L12

also, it should make that media/latex with mkdir command: https://github.com/end-4/dots-hyprland/blob/a94172d9cd860113926e2c6fd7375c547564dc76/.config/ags/modules/sideleft/apis/ai_chatmessage.js#L75-L77

@end-4 maybe missing quotes in bash -c? like bash -c mkdir -p ${LATEX_DIR} --> bash -c "mkdir -p ${LATEX_DIR}"

[end-4]

the problem was this "rm: cannot remove '/home/end/.cache/ags/media/latex/*': No such file or directory" idk why the asterisk didn't work, but i made it rm -rf the whole folder instead and it should work now

[end-4]

i'll also have to see if that aur package works

[l4v3nx]

it provides stuff in res/ but doesn't provide the binary. you may remove the line in installer that copies res/ to /usr/local/bin/ and add microtex-git to deps (1.5 mb size, pretty small)

[l4v3nx]

@end-4 btw ai answer still can't be formated to latex (it just shows answer header (like "Common trigonometric formulas") and both the answer generation and ags itself completely crash (yes, real ags crash moment))

ags.log

(703 errors in 20 seconds)

prompt: name common trig formulas (put them into latex code blocks) precise, enhancements on

/test shows formatting fine
