Hi,
How does one save and read third-party data in tuc file at the lua end?
I am trying to write a module t-ifchanged that defines a \doiffilechanged
macro that provides the functionality of mtxrun --ifchanged without
calling an external program (This is meant to be a support module for
t-vim, where the external calls to mtxrun are too time consuming).
I can successfully write additional data to the tuc file, but cannot
figure out how to initialize the data from tuc file. (See attached file).
Any hints are welcome.
Aditya

You can read the data with loadfile or dofile:
utilitydata=dofile('test.tuc')
and then you have the table stored into utilitydata
See for the difference with loadfile

This is why we have a mechanism built in (used for graphics).

There is:
jobfiles.run("yourfile.xxx","vim --something yourfile.xxx")
I'll adapt this to accept a function as second argument.

Ah, I didn't know that.

This works in a standalone file, but not the way I am calling the
function.
\def\executeCommand
{\doifmode{*first}
{\ctxlua{job.files.run(\!!bs\externalfiter::input_file\!!es,
\!!bs\externalfiltercommand\!!es)}}}
The solution is to remove the test for the first mode. Needs a bit of
refactoring to ensure that the solution still works for MkII. (Does anyone
use the filter module with MkII?)
