Hello, and thanks!

I'm having trouble in one case using run to generate rules, with tup v0.8-4-g748b7c7d.

This is a working, but repetitive Tupfile:

Tupfile

I want to use tup's run to generate most of these, using wheezy.template (from PyPI). So I replace the Tupfile content with:

run wheezy.template templates/tup.rules.wz

And create templates/tup.rules.wz:

wheezy template

@end

If I manually run wheezy.template templates/tup.rules.wz, the stdout is identical to the original Tupfile.

But when I run tup --debug-run, I get:

tup --debug-run output

IIRC run scripts expect every line to be an : rule and does not accept blank lines or comments, unlike the syntax recognized in Tupfiles. I remember having to take measures to get around a similar error, anyway, by skipping blank lines.

Answer 2 · 2024-05-31T16:34:32.000Z

@earthlyreason Thanks so much! That's it, all good now.

I would prefer to be able to include blank lines, and to a lesser extent comments, but I can put comments in the template file so that's not too bad.

Answer 3 · 2024-06-07T00:58:03.000Z

I pushed 4247a52 to skip blank lines (completely blank, as in just a newline), as well as lines starting with #

Have you tried the built-in lua support for rules at all? I'm curious how that compares to this template style in your experience.

Answer 4 · 2024-06-07T16:50:00.000Z

Thanks!

Sorry, I haven't tried using lua for rules, as I don't enjoy writing lua and am quite bad at it. I use wheezy.template a lot for various small projects and am happy with it.
