Replaced all instances of 'python' with 'python2' On systems where 'python' refers to python3, redo failed to launch. All invocations of python have been made explicitly python2 invocations. All tests pass on an Arch Linux system as of this commit. 2018-11-14 10:52:04 -08:00			`#!/usr/bin/env python2`
Add redo-ifcreate to match djb's design. I'm not quite sure why this needs to be a separate program, however, so I'm probably not testing it correctly. 2010-11-13 01:10:43 -08:00			`import sys, os`
Extract .redo dir state management stuff into its own file. In preparation for changing the on-disk format eventually, as well as making the main code more readable. 2010-11-19 03:03:05 -08:00			`import vars, state`
The only thing in helpers.py that needed vars.py was the log stuff. So put it in its own file. Now it's safer to import and use helpers even if you can't safely touch vars. 2010-12-11 18:32:40 -08:00			`from log import err`

Print a nicer error message when asked to build an empty string (''). This happens sometimes, for example, if you do whatever \| while read x; do redo-ifchange "$x" done and the input contains blank lines. We could ignore the request for blankness, but it seems like that situation might indicate a more serious bug in your parser, so it's probably better to just abort with a meaningful error. 2018-11-03 03:36:13 -04:00			`if not t:`

Add a redo-ifcreate test. Turns out we weren't testing this one at all, which is a shame, because it totally didn't work. 2010-12-11 23:42:31 -08:00			`state.commit()`
