configuring latex path from within mnemosyne

[Jakob]

Hi,
I'm using mnemosyne a lot on public pcs (e.g. library) via usb stick.
While this is working fine most of the time I can't get it to use
latex, which is also working fine on its own from usb ("MikTex
Portable"). So obviously Mnemosyne is looking in the standard path for
the latex executables, but they are not installed there (as it is only
a cheap public pc with almost no software, windows xp) and I cannot
change the path variables or copy miktex to the system path (as I am
only a guest user, so no fancy admin stuff). So I only need to tell
Mnemosyne something like: forget the standard paths when you want to
use latex go to myUSB/latexdirectory
It seems to be very sensible that this should be something I can do
somewhere in the config files of mnemosyne, but I just could not find
the option to do so yet. Copying mnemosyne to the miketex directory
and starting it from there, didn't seem to make any change. So, can I
tell mnemosyne to do all the latex stuff from a particular directory
(and I mean not telling windows to do so, as I am not allowed to)?

And if you don't specify a path in config.py, but rather simply 'latex'
and set the paths at the os level?

I'll see if I can reproduce this. Make sure to use the latest Mnemosyne,
though (2.2a).

Cheers,

Peter

Hi,

I don't really support anything not coming from the Mnemosyne website.

Have you tried this:

I'm about to leave for travel soon, but I'll have a look at it when I
come back in a few weeks.

Cheers,

Got this to work, but make sure you use double slashes when you specify the path, like f:\\miktex\\miktex\\bin\\latex.exe

Cheers,

I appreciate that, thanks. As a point of clarification, generally you expect the latex executable to be present in the PATH, correct?

Does specifying a latex.exe location (either absolute or relative) typically work?

[Peter Bienstman]

From F:\Mnemosyne\mnemosyne\config.py:

# Latex command.
latex = "F:\\miktex\\miktex\\bin\\latex.exe -interaction=nonstopmode"

# Latex dvipng command.
dvipng = "F:\\miktex\\miktex\\bin\\dvipng.exe -D 200 -T tight tmp.dvi"

I suggest you try the dvipng command from the command line too, as
perhaps there are missing miktex packages that need to be installed first.

Good luck!

My portable miktex works fine, and if I compile the generated tmp.tex (and subsequent tmp.div) everything comes out perfectly. However, when I try to specify a latex.exe and dvipng.exe path in config.py, I get the "Problem with latex. Are latex and dvipng?" message within Mnemosyne.

[Peter Bienstman]

The current working directory before executing the latex command is
the latex dir, i.e. default.db/media/_latex, so you'll need to add a
few more ..\\

Cheers,

Peter
