A universal "diff" patch parsing library.
Project description
The parsedifflib package parses any style of diff patch into an event stream of patch instructions. These instructions can then be applied, colorized, reformatted, dissected, analyzed, etc.
Warning
2013/12/09: currently only the svnlook format and stream-oriented event output is supported. Eventually, all the formats supported by colordiff are intended to be supported as well as structured output.
Usage
import parsedifflib, subprocess data = subprocess.check_output('svnlook diff /path/to/repos', shell=True) for event, target in parsedifflib.parse_svnlook(data, {'lineNumbers': True}): if event in ( parsedifflib.Event.PATCH_START, parsedifflib.Event.PATCH_END, parsedifflib.Event.ENTRY_END, parsedifflib.Event.LINE_LOC, parsedifflib.Event.LINE_SAME, parsedifflib.Event.LINE_NOTE, parsedifflib.Event.PROPENTRY, ): continue elif event == parsedifflib.Event.ENTRY_START: print target.comment elif event == parsedifflib.Event.LINE_DELETE: print ' - deleted line %d: %s' % (target.oldnum, target.line) elif event == parsedifflib.Event.LINE_DELETE: print ' + added line %d: %s' % (target.newnum, target.line)
