martinvonz/jj v0.19.0

on GitHub

Breaking changes

• In revset aliases, top-level kind:pattern expression is now parsed as
  modifier. Surround with parentheses if it should be parsed as string/file
  pattern.

• Dropped support for automatic upgrade of repo formats used by versions before
  0.12.0.

• jj fix now defaults to the broader revset -s reachable(@, mutable())
  instead of -s @.

• Dropped support for deprecated jj branch delete/forget --glob option.

• jj branch set now creates new branch if it doesn't exist. Use jj branch move to ensure that the target branch already exists.
  #3584

Deprecations

• Replacing -l shorthand for --limit with -n in jj log, jj op log
  and jj obslog.

• jj split --siblings is deprecated in favor of jj split --parallel (to
  match jj parallelize).

• A new jj file subcommand now replaces several existing uncategorized
  commands, which are deprecated.

  • jj file show replaces jj cat.
  • jj file chmod replaces jj chmod.
  • jj file list replaces jj files.

New features

• Support background filesystem monitoring via watchman triggers enabled with
  the core.watchman.register_snapshot_trigger = true config.

• Show paths to config files when configuration errors occur.

• jj fix now supports configuring the default revset for -s using the
  revsets.fix config.

• The descendants() revset function now accepts an optional depth argument;
  like the ancestors() depth argument, it limits the depth of the set.

• Revset/template aliases now support function overloading.
  #2966

• Conflicted files are individually simplified before being materialized.

• The jj file subcommand now contains several existing file utilities.

  • jj file show, replacing jj cat.
  • jj file chmod replacing jj chmod.
  • jj file list replacing jj files.

• New command jj branch move let you update branches by name pattern or source
  revision.

• New diff option jj diff --name-only allows for easier shell scripting.

• In color-words diffs, hunks are now highlighted with underline. See diff
  colors and styles for customization.

• jj git push -c <arg> can now accept revsets that resolve to multiple
  revisions. This means that jj git push -c xyz -c abc is now equivalent to
  jj git push -c 'all:(xyz | abc)'.

• jj prev and jj next have gained a --conflict flag which moves you
  to the next conflict in a child commit.

• New command jj git remote set-url that sets the url of a git remote.

• Author timestamp is now reset when rewriting discardable commits (empty
  commits with no description) if authored by the current user.
  #2000

• jj commit now accepts --reset-author option to match jj describe.

• jj squash now accepts a --keep-emptied option to keep the source commit.

Fixed bugs

• jj git push now ignores immutable commits when checking whether a
  to-be-pushed commit has conflicts, or has no description / committer / author
  set. #3029

• jj will look for divergent changes outside the short prefix set even if it
  finds the change id inside the short prefix set.
  #2476
