'''manage a stack of patches This extension lets you work with a stack of patches in a Mercurial repository. It manages two stacks of patches - all known patches, and applied patches (subset of known patches). Known patches are represented as patch files in the .hg/patches directory. Applied patches are both patch files and changesets. Common tasks (use :hg:`help command` for more details):: create new patch qnew import existing patch qimport print patch series qseries print applied patches qapplied add known patch to applied stack qpush remove patch from applied stack qpop refresh contents of top applied patch qrefresh By default, mq will automatically use git patches when required to avoid losing file mode changes, copy records, binary files or empty files creations or deletions. This behavior can be configured with:: [mq] git = auto/keep/yes/no If set to 'keep', mq will obey the [diff] section configuration while preserving existing git patches upon qrefresh. If set to 'yes' or 'no', mq will override the [diff] section and always generate git or regular patches, possibly losing data in the second case. It may be desirable for mq changesets to be kept in the secret phase (see :hg:`help phases`), which can be enabled with the following setting:: [mq] secret = True You will by default be managing a patch queue named "patches". You can create other, independent patch queues with the :hg:`qqueue` command. If the working directory contains uncommitted files, qpush, qpop and qgoto abort immediately. If -f/--force is used, the changes are discarded. Setting:: [mq] keepchanges = True make them behave as if --keep-changes were passed, and non-conflicting local changes will be tolerated and preserved. If incompatible options such as -f/--force or --exact are passed, this setting is ignored. This extension used to provide a strip command. This command now lives in the strip extension.
