The evolve command resolves your troubles - by executing one of the following actions: - - - update working copy to a successor - - rebase an unstable changeset - - extract the desired changes from a bumped changeset - - fuse divergent changesets back together - - If you pass no arguments, evolve works in automatic mode: it will execute a - single action to reduce instability related to your working copy. There are - two cases for this action. First, if the parent of your working copy is - obsolete, evolve updates to the parent's successor. Second, if the working - copy parent is not obsolete but has obsolete predecessors, then evolve - determines if there is an unstable changeset that can be rebased onto the - working copy parent in order to reduce instability. - If so, evolve rebases that changeset. If not, evolve refuses to guess your - intention, and gives a hint about what you might want to do next. - - Any time evolve creates a changeset, it updates the working copy to the new - changeset. (Currently, every successful evolve operation involves an update - as well; this may change in future.) - - Automatic mode only handles common use cases. For example, it avoids taking - action in the case of ambiguity, and it ignores unstable changesets that - are not related to your working copy. - It also refuses to solve bumped or divergent changesets unless you explicity - request such behavior (see below). - - Eliminating all instability around your working copy may require multiple - invocations of :hg:`evolve`. Alternately, use ``--all`` to recursively - select and evolve all unstable changesets that can be rebased onto the - working copy parent. - This is more powerful than successive invocations, since ``--all`` handles - ambiguous cases (e.g. unstable changesets with multiple children) by - evolving all branches. - - When your repository cannot be handled by automatic mode, you might need to - use ``--rev`` to specify a changeset to evolve. For example, if you have - an unstable changeset that is not related to the working copy parent, - you could use ``--rev`` to evolve it. Or, if some changeset has multiple - unstable children, evolve in automatic mode refuses to guess which one to - evolve; you have to use ``--rev`` in that case. - - Alternately, ``--any`` makes evolve search for the next evolvable changeset - regardless of whether it is related to the working copy parent. - - You can supply multiple revisions to evolve multiple troubled changesets - in a single invocation. In revset terms, ``--any`` is equivalent to ``--rev - first(unstable())``. ``--rev`` and ``--all`` are mutually exclusive, as are - ``--rev`` and ``--any``. - - ``hg evolve --any --all`` is useful for cleaning up instability across all - branches, letting evolve figure out the appropriate order and destination. - - When you have troubled changesets that are not unstable, :hg:`evolve` - refuses to consider them unless you specify the category of trouble you - wish to resolve, with ``--bumped`` or ``--divergent``. These options are - currently mutually exclusive with each other and with ``--unstable`` - (the default). You can combine ``--bumped`` or ``--divergent`` with - ``--rev``, ``--all``, or ``--any``. - - You can also use the evolve command to list the troubles affecting your - repository by using the --list flag.

The evolve command resolves your troubles + by executing one of the following actions: + + - update working copy to a successor + - rebase an unstable changeset + - extract the desired changes from a bumped changeset + - fuse divergent changesets back together + + If you pass no arguments, evolve works in automatic mode: it will execute a + single action to reduce instability related to your working copy. There are + two cases for this action. First, if the parent of your working copy is + obsolete, evolve updates to the parent's successor. Second, if the working + copy parent is not obsolete but has obsolete predecessors, then evolve + determines if there is an unstable changeset that can be rebased onto the + working copy parent in order to reduce instability. + If so, evolve rebases that changeset. If not, evolve refuses to guess your + intention, and gives a hint about what you might want to do next. + + Any time evolve creates a changeset, it updates the working copy to the new + changeset. (Currently, every successful evolve operation involves an update + as well; this may change in future.) + + Automatic mode only handles common use cases. For example, it avoids taking + action in the case of ambiguity, and it ignores unstable changesets that + are not related to your working copy. + It also refuses to solve bumped or divergent changesets unless you explicity + request such behavior (see below). + + Eliminating all instability around your working copy may require multiple + invocations of :hg:`evolve`. Alternately, use ``--all`` to recursively + select and evolve all unstable changesets that can be rebased onto the + working copy parent. + This is more powerful than successive invocations, since ``--all`` handles + ambiguous cases (e.g. unstable changesets with multiple children) by + evolving all branches. + + When your repository cannot be handled by automatic mode, you might need to + use ``--rev`` to specify a changeset to evolve. For example, if you have + an unstable changeset that is not related to the working copy parent, + you could use ``--rev`` to evolve it. Or, if some changeset has multiple + unstable children, evolve in automatic mode refuses to guess which one to + evolve; you have to use ``--rev`` in that case. + + Alternately, ``--any`` makes evolve search for the next evolvable changeset + regardless of whether it is related to the working copy parent. + + You can supply multiple revisions to evolve multiple troubled changesets + in a single invocation. In revset terms, ``--any`` is equivalent to ``--rev + first(unstable())``. ``--rev`` and ``--all`` are mutually exclusive, as are + ``--rev`` and ``--any``. + + ``hg evolve --any --all`` is useful for cleaning up instability across all + branches, letting evolve figure out the appropriate order and destination. + + When you have troubled changesets that are not unstable, :hg:`evolve` + refuses to consider them unless you specify the category of trouble you + wish to resolve, with ``--bumped`` or ``--divergent``. These options are + currently mutually exclusive with each other and with ``--unstable`` + (the default). You can combine ``--bumped`` or ``--divergent`` with + ``--rev``, ``--all``, or ``--any``. + + You can also use the evolve command to list the troubles affecting your + repository by using the --list flag.
