Hi TextMaters,
I have a very superficial knowledge of perl, so I wonder if someone can help. Setup: before I compile my LaTeX document, I need to run a shell script (using sed) to find/replace certain strings. [There is a long story for why I need to do this, and why its not easily avoidable.]
Possible solution: I was wondering if I can insert something in the latex_watch.pl script that would run this shell script, without causing latex_watch to go into an infinite loop (since the shell script changes the underlying LaTeX file/s).
I've tried inserting the relevant code in several locations, but I can't seem to avoid the loop. That's not surprising, since I don't really know perl. Does anyone know if there is easy way to
- modify latex_watch.pl so it executes a shell script that modifies the underlying LaTeX file without going in to a loop?
or
since the main loop of `latex_watch.pl` triggers the compilation after file changes, I don't think there is an easy way to execute your script in there, without causing an infinite loop.
- cause the shell script to run on the file whenever the file changes by some other means?
That sounds like a good idea. You can use `callback.document.will-save` for that. A command with this semantic class will be called just before you save a file. E.g. To replace every occurrence of the word `bla` with the word `blubb` in tex files, create a command with the following content:
#!/bin/bash
sed s/bla/blubb/g
Use the following options:
Scope Selector: text.tex Semantic Class: callback.document.will-save Save: Nothing Input: Document Format: Text Output: Replace Input Format: Text Caret Placement: Line Interpolation
I included a bundle with one command called “Replace Strings” which does exactly that. You can extend this command by replacing `sed s/bla/blubb/g` with the name of your shell script. Just make sure that your shell script works with input from standard input (`STDIN`).
Thanks! Zvi
Kind regards, René
