v0.7.0

[martinvonz]

Breaking changes

• The minimum supported Rust version (MSRV) is now 1.61.0.

• The jj touchup command was renamed to jj diffedit.

• The -i option to jj restore was removed in favor of new --from/--to
  options to jj diffedit.

• To report the situation when a change id corresponds to multiple visible
  commits, jj log now prints the change id in red and puts ?? after it.
  Previously, it printed the word "divergent".

• jj log prefixes commit descriptions with "(empty)" when they contain no
  change compared to their parents.

• The author/committer templates now display both name and email. Use
  author.name()/committer.name() to extract the name.

• Storage of the "HEAD@git" reference changed and can now have conflicts.
  Operations written by a new jj binary will have a "HEAD@git" reference that
  is not visible to older binaries.

• The description template keyword is now empty if no description set.
  Use if(description, description, "(no description set)\n") to get back
  the previous behavior.

• The template.log.graph and template.commit_summary config keys were
  renamed to templates.log and templates.commit_summary respectively.

• If a custom templates.log template is set, working-copy commit will
  no longer be highlighted automatically. Wrap your template with
  label(if(current_working_copy, "working_copy"), ...) to label the
  working-copy entry.

• The ui.relative-timestamps option has been removed. Use the
  format_timestamp() template alias instead. For details on showing relative
  timestamps in jj log and jj show, see the documentation.

• jj op log now shows relative timestamps by default. To disable, set
  ui.oplog-relative-timestamps to false.

• The global --no-commit-working-copy is now called --ignore-working-copy.

• The diff.format config option is now called ui.diff.format. The old name
  is still supported for now.

• merge-tools.<name>.edit-args now requires $left/$right parameters.
  The default is edit-args = ["$left", "$right"].

• The builtin jj update and jj up aliases for jj checkout have been
  deleted.

• Change IDs are now rendered using letters from the end of the alphabet (from
  'z' through 'k') instead of the usual hex digits ('0' through '9' and 'a'
  through 'f'). This is to clarify the distinction between change IDs and commit
  IDs, and to allow more efficient lookup of unique prefixes. This change
  doesn't affect the storage format; existing repositories will remain usable.

New features

• The default log format now uses the committer timestamp instead of the author
  timestamp.

• jj log --summary --patch now shows both summary and diff outputs.

• jj git push now accepts multiple --branch/--change arguments

• jj config list command prints values from config and config edit opens
  the config in an editor.

• jj debug config-schema command prints out JSON schema for the jj TOML config
  file format.

• jj resolve --list can now describe the complexity of conflicts.

• jj resolve now notifies the user of remaining conflicts, if any, on success.
  This can be prevented by the new --quiet option.

• Per-repository configuration is now read from .jj/repo/config.toml.

• Background colors, bold text, and underlining are now supported. You can set
  e.g. color.error = { bg = "red", bold = true, underline = true } in your
  ~/.jjconfig.toml.

• The empty condition in templates is true when the commit makes no change to
  the three compared to its parents.

• branches([needle]) revset function now takes needle as an optional
  argument and matches just the branches whose name contains needle.

• remote_branches([branch_needle[, remote_needle]]) now takes branch_needle
  and remote_needle as optional arguments and matches just the branches whose
  name contains branch_needle and remote contains remote_needle.

• jj git fetch accepts repeated --remote arguments.

• Default remotes can be configured for the jj git fetch and jj git push
  operations ("origin" by default) using the git.fetch and git.push
  configuration entries. git.fetch can be a list if multiple remotes must
  be fetched from.

• jj duplicate can now duplicate multiple changes in one go. This preserves
  any parent-child relationships between them. For example, the entire tree of
  descendants of abc can be duplicated with jj duplicate abc:.

• jj log now highlights the shortest unique prefix of every commit and change
  id and shows the rest in gray. To customize the length and style, use the
  format_short_id() template alias. For details, see
  the documentation.

• jj print was renamed to jj cat. jj print remains as an alias.

• In content that goes to the terminal, the ANSI escape byte (0x1b) is replaced
  by a "␛" character. That prevents them from interfering with the ANSI escapes
  jj itself writes.

• jj workspace root prints the root path of the current workspace.

• The [alias] config section was renamed to [aliases]. The old name is
  still accepted for backwards compatibility for some time.

• Commands that draw an ASCII graph (jj log, jj op log, jj obslog) now
  have different styles available by setting e.g. ui.graph.style = "curved".

• jj split accepts creating empty commits when given a path. jj split .
  inserts an empty commit between the target commit and its children if any,
  and jj split any-non-existent-path inserts an empty commit between the
  target commit and its parents.

• Command arguments to ui.diff-editor/ui.merge-editor can now be specified
  inline without referring to [merge-tools] table.

• jj rebase now accepts a new --allow-large-revsets argument that allows the
  revset in the -d argument to expand to several revisions. For example,
  jj rebase -s B -d B- -d C now works even if B is a merge commit.

• jj new now also accepts a --allow-large-revsets argument that behaves
  similarly to jj rebase --allow-large-revsets.

• jj new --insert-before inserts the new commit between the target commit and
  its parents.

• jj new --insert-after inserts the new commit between the target commit and
  its children.

• author/committer templates now support .username(), which leaves out the
  domain information of .email().

• It is now possible to change the author format of jj log with the
  format_short_signature() template alias. For details, see
  the documentation.

• Added support for template aliases. New symbols and functions can be
  configured by template-aliases.<name> = <expression>. Be aware that
  the template syntax isn't documented yet and is likely to change.

Fixed bugs

• When sharing the working copy with a Git repo, we used to forget to export
  branches to Git when only the working copy had changed. That's now fixed.

• Commit description set by -m/--message is now terminated with a newline
  character, just like descriptions set by editor are.

• The -R/--repository path must be a valid workspace directory. Its
  ancestor directories are no longer searched.

• Fixed a crash when trying to access a commit that's never been imported into
  the jj repo from a Git repo. They will now be considered as non-existent if
  referenced explicitly instead of crashing.

• Fixed handling of escaped characters in .gitignore (only keep trailing spaces
  if escaped properly).

• jj undo now works after jj duplicate.

• jj duplicate followed by jj rebase of a tree containing both the original
  and duplicate commit no longer crashes. The fix should also resolve any remaining
  instances of jj close (and some others) sometimes crashes on first attempt with Git backend #27.

• Fix the output of jj debug completion --help by reversing fish and zsh text.

• Fixed edge case in jj git fetch when a pruned branch is a prefix of another
  branch.
