v0.17.0

[martinvonz]

Breaking changes

• The default template aliases were replaced as follows:

  • builtin_op_log_root(op_id: OperationId) ->
    format_root_operation(root: Operation)
  • builtin_log_root(change_id: ChangeId, commit_id: CommitId) ->
    format_root_commit(root: Commit)
  • builtin_change_id_with_hidden_and_divergent_info ->
    format_short_change_id_with_hidden_and_divergent_info(commit: Commit)

• The --revision option of jj rebase is renamed to --revisions. The short
  alias -r is still supported.

New features

• The list of conflicted paths is printed whenever the working copy changes.
  This can be disabled with the --quiet option.

• Commit objects in templates now have a mine() -> Boolean method analog to
  the same function in revsets. It evaluates to true if the email of the commit
  author matches the current user.email.

• Commit objects in templates now have a contained_in(revset: String) -> Boolean method.

• Operation objects in templates now have a snapshot() -> Boolean method that
  evaluates to true if the operation was a snapshot created by a non-mutating
  command (e.g. jj log).

• Revsets and templates now support single-quoted raw string literals.

• A new config option ui.always-allow-large-revsets has been added to
  allow large revsets expressions in some commands, without the all: prefix.

• A new config option ui.allow-filesets has been added to enable "fileset"
  expressions. Note that filesets are currently experimental,
  but will be enabled by default in a future release.

• A new global flag --ignore-immutable lets you rewrite immutable commits.

• New command jj parallelize that rebases a set of revisions into siblings.

• jj status now supports filtering by paths. For example, jj status . will
  only list changed files that are descendants of the current directory.

• jj prev and jj next now work when the working copy revision is a merge.

• jj squash now accepts a --use-destination-message/-u option that uses the
  description of the destination for the new squashed revision and discards the
  descriptions of the source revisions.

• You can check whether Watchman fsmonitor is enabled or installed with the new
  jj debug watchman status command.

• jj rebase now accepts revsets resolving to multiple revisions with the
  --revisions/-r option.

• jj rebase -r now accepts --insert-after and --insert-before options to
  customize the location of the rebased revisions.

Fixed bugs

• Revsets now support \-escapes in string literal.

• The builtin diff editor now allows empty files to be selected during
  jj split.

• Fixed a bug with jj split introduced in 0.16.0 that caused it to incorrectly
  rebase the children of the revision being split if they had other parents
  (i.e. if the child was a merge).

• The snapshot.max-new-file-size option can now handle raw integer literals,
  interpreted as a number of bytes, where previously it could only handle string
  literals. This means that snapshot.max-new-file-size="1" and
  snapshot.max-new-file-size=1 are now equivalent.

• jj squash <path> is now a no-op if the path argument didn't match any paths
  (it used to create new commits with bumped timestamp).
