annotate mercurial/packagescan.py @ 1907:7718885070b1

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
let commands that show changesets use templates. mechanism is same as hgweb templates. old show_changeset code is still used for now if no template given, because it is faster than template code when verbose or debug. simple template can be given on command line using -t, --template. example: hg log -t '{author|person}\n' complex template can be put in template map file, given on command line using --map-file. we give two example map files: map-log.compact prints 3 lines of output for every change. map-log.verbose prints exact same output as default "hg log -v". map files are searched where user says, then in template path as backup. example: hg log --map-file map-log.compact defaults can be set in hgrc with ui.logtemplate and ui.logmap.
