# Changelog All notable changes to this project will be documented in this file. The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). ## [Unreleased] ### Breaking changes * Dropped candidates set argument from `description(needle)`, `author(needle)`, `committer(needle)`, `merges()` revsets. Use `x & description(needle)` instead. * Adjusted precedence of revset union/intersection/difference operators. `x | y & z` is now equivalent to `x | (y & z)`. * Support for open commits has been dropped. The `ui.enable-open-commits` config that was added in 0.5.0 is no longer respected. The `jj open/close` commands have been deleted. * `jj commit` is now a separate command from `jj close` (which no longer exists). The behavior has changed slightly. It now always asks for a description, even if there already was a description set. It now also only works on the working-copy commit (there's no `-r` argument). ### New features * Commands with long output are paginated. * The new `jj git remote rename` command allows git remotes to be renamed in-place. * The new `jj resolve` command allows resolving simple conflicts with an external 3-way-merge tool. * `jj git push` will search `@-` for branches to push if `@` has none. * The new revset function `file(pattern..)` finds commits modifying the paths specified by the `pattern..`. * The new revset function `empty()` finds commits modifying no files. * Added support for revset aliases. New symbols and functions can be configured by `revset-aliases. = `. * It is now possible to specify configuration options on the command line with the new `--config-toml` global option. * `jj git` subcommands will prompt for credentials when required for HTTPS remotes rather than failing. [#469](https://github.com/martinvonz/jj/issues/469) * Branches that have a different target on some remote than they do locally are now indicated by an asterisk suffix (e.g. `main*`) in `jj log`. [#254](https://github.com/martinvonz/jj/issues/254) * The commit ID was moved from first on the line in `jj log` output to close to the end. The goal is to encourage users to use the change ID instead, since that is generally more convenient, and it reduces the risk of creating divergent commits. * The username and hostname that appear in the operation log are now configurable via config options `operation.username` and `operation.hostname`. * `jj git` subcommands now support credential helpers. * `jj log` will warn if it appears that the provided path was meant to be a revset. * The new global flag `-v/--verbose` will turn on debug logging to give some additional insight into what is happening behind the scenes. Note: This is not comprehensively supported by all operations yet. * `jj log`, `jj show`, and `jj obslog` now all support showing relative timestamps by setting `ui.relative-timestamps = true` in the config file. ### Fixed bugs * A bug in the export of branches to Git caused spurious conflicted branches. This typically occurred when running in a working copy colocated with Git (created by running `jj init --git-dir=.`). [#463](https://github.com/martinvonz/jj/issues/463) * When exporting branches to Git, we used to fail if some branches could not be exported (e.g. because Git doesn't allow a branch called `main` and another branch called `main/sub`). We now print a warning about these branches instead. [#493](https://github.com/martinvonz/jj/issues/493) * If you had modified branches in jj and also modified branches in conflicting ways in Git, `jj git export` used to overwrite the changes you made in Git. We now print a warning about these branches instead. * `jj edit root` now fails gracefully. * `jj git import` used to abandon a commit if Git branches and tags referring to it were removed. We now keep it if a detached HEAD refers to it. * `jj git import` no longer crashes when all Git refs are removed. * Git submodules are now ignored completely. Earlier, files present in the submodule directory in the working copy would become added (tracked), and later removed if you checked out another commit. You can now use `git` to populate the submodule directory and `jj` will leave it alone. ### Contributors Thanks to the people who made this release happen! * Martin von Zweigbergk (@martinvonz) * Benjamin Saunders (@Ralith) * Yuya Nishihara (@yuja) * Glen Choo (@chooglen) * Ilya Grigoriev (@ilyagr) * Ruben Slabbert (@rslabbert) * Waleed Khan (@arxanas) * Sean E. Russell (@xxxserxxx) * Pranay Sashank (@pranaysashank) ## [0.5.1] - 2022-10-17 No changes (just trying to get automated GitHub release to work). ## [0.5.0] - 2022-10-17 ### Breaking changes * Open commits are now disabled by default. That means that `jj checkout` will always create a new change on top of the specified commit and will let you edit that in the working copy. Set `ui.enable-open-commits = true` to restore the old behavior and let us know that you did so we know how many people prefer the workflow with open commits. * `jj [op] undo` and `jj op restore` used to take the operation to undo or restore to as an argument to `-o/--operation`. It is now a positional argument instead (i.e. `jj undo -o abc123` is now written `jj undo abc123`). * An alias that is not configured as a string list (e.g. `my-status = "status"` instead of `my-status = ["status"]`) is now an error instead of a warning. * `jj log` now defaults to showing only commits that are not on any remote branches (plus their closest commit on the remote branch for context). This set of commits can be overridden by setting `ui.default-revset`. Use `jj log -r 'all()'` for the old behavior. Read more about revsets [here](https://github.com/martinvonz/jj/blob/main/docs/revsets.md). [#250](https://github.com/martinvonz/jj/issues/250) * `jj new` now always checks out the new commit (used to be only if the parent was `@`). * `jj merge` now checks out the new commit. The command now behaves exactly like `jj new`, except that it requires at least two arguments. * When the working-copy commit is abandoned by `jj abandon` and the parent commit is open, a new working-copy commit will be created on top (the open parent commit used to get checked out). * `jj branch` now uses subcommands like `jj branch create` and `jj branch forget` instead of options like `jj branch --forget`. [#330](https://github.com/martinvonz/jj/issues/330) * The [`$NO_COLOR` environment variable](https://no-color.org/) no longer overrides the `ui.color` configuration if explicitly set. * `jj edit` has been renamed to `jj touchup`, and `jj edit` is now a new command with different behavior. The new `jj edit` lets you edit a commit in the working copy, even if the specified commit is closed. * `jj git push` no longer aborts if you attempt to push an open commit (but it now aborts if a commit does not have a description). * `jj git push` now pushes only branches pointing to the `@` by default. Use `--all` to push all branches. * The `checkouts` template keyword is now called `working_copies`, and `current_checkout` is called `current_working_copy`. ### New features * The new `jj interdiff` command compares the changes in commits, ignoring changes from intervening commits. * `jj rebase` now accepts a `--branch/-b ` argument, which can be used instead of `-r` or `-s` to specify which commits to rebase. It will rebase the whole branch, relative to the destination. The default mode has changed from `-r @` to `-b @`. * The new `jj print` command prints the contents of a file in a revision. * The new `jj git remotes list` command lists the configured remotes and their URLs. [#243](https://github.com/martinvonz/jj/issues/243) * `jj move` and `jj squash` now lets you limit the set of changes to move by specifying paths on the command line (in addition to the `--interactive` mode). For example, use `jj move --to @-- foo` to move the changes to file (or directory) `foo` in the working copy to the grandparent commit. * When `jj move/squash/unsquash` abandons the source commit because it became empty and both the source and the destination commits have non-empty descriptions, it now asks for a combined description. If either description was empty, it uses the other without asking. * `jj split` now lets you specify on the CLI which paths to include in the first commit. The interactive diff-editing is not started when you do that. * Sparse checkouts are now supported. In fact, all working copies are now "sparse", only to different degrees. Use the `jj sparse` command to manage the paths included in the sparse checkout. * Configuration is now also read from `~/.jjconfig.toml`. * The `$JJ_CONFIG` environment variable can now point to a directory. If it does, all files in the directory will be read, in alphabetical order. * The `$VISUAL` environment is now respected and overrides `$EDITOR`. The new `ui.editor` config has higher priority than both of them. There is also a new `$JJ_EDITOR` environment variable, which has even higher priority than the config. * You can now use `-` and `+` in revset symbols. You used to have to quote branch names like `my-feature` in nested quotes (outer layer for your shell) like `jj co '"my-feature"'`. The quoting is no longer needed. * The new revset function `connected(x)` is the same as `x:x`. * The new revset function `roots(x)` finds commits in the set that are not descendants of other commits in the set. * ssh-agent is now detected even if `$SSH_AGENT_PID` is not set (as long as `$SSH_AUTH_SOCK` is set). This should help at least macOS users where ssh-agent is launched by default and only `$SSH_AUTH_SOCK` is set. * When importing from a git, any commits that are no longer referenced on the git side will now be abandoned on the jj side as well. That means that `jj git fetch` will now abandon unreferenced commits and rebase any local changes you had on top. * `jj git push` gained a `--change ` argument. When that's used, it will create a branch named after the revision's change ID, so you don't have to create a branch yourself. By default, the branch name will start with `push-`, but this can be overridden by the `push.branch-prefix` config setting. * `jj git push` now aborts if you attempt to push a commit without a description or with the placeholder "(no name/email configured)" values for author/committer. * Diff editor command arguments can now be specified by config file. Example: [merge-tools.kdiff3] program = "kdiff3" edit-args = ["--merge", "--cs", "CreateBakFiles=0"] * `jj branch` can accept any number of branches to update, rather than just one. * Aliases can now call other aliases. * `jj log` now accepts a `--reversed` option, which will show older commits first. * `jj log` now accepts file paths. * `jj obslog` now accepts `-p`/`--patch` option, which will show the diff compared to the previous version of the change. * The "(no name/email configured)" placeholder value for name/email will now be replaced if once you modify a commit after having configured your name/email. * Color setting can now be overridden by `--color=always|never|auto` option. * `jj checkout` now lets you specify a description with `--message/-m`. * `jj new` can now be used for creating merge commits. If you pass more than one argument to it, the new commit will have all of them as parents. ### Fixed bugs * When rebasing a conflict where one side modified a file and the other side deleted it, we no longer automatically resolve it in favor of the modified content (this was a regression from commit c0ae4b16e8c4). * Errors are now printed to stderr (they used to be printed to stdout). * Updating the working copy to a commit where a file's executable bit changed but the contents was the same used to lead to a crash. That has now been fixed. * If one side of a merge modified a directory and the other side deleted it, it used to be considered a conflict. The same was true if both sides added a directory with different files in. They are now merged as if the missing directory had been empty. * When using `jj move` to move part of a commit into an ancestor, any branches pointing to the source commit used to be left on a hidden intermediate commit. They are now correctly updated. * `jj untrack` now requires at least one path (allowing no arguments was a UX bug). * `jj rebase` now requires at least one destination (allowing no arguments was a UX bug). * `jj restore --to ` now restores from the working copy (it used to restore from the working copy's parent). * You now get a proper error message instead of a crash when `$EDITOR` doesn't exist or exits with an error. * Global arguments, such as `--at-op=`, can now be passed before an alias. * Fixed relative path to the current directory in output to be `.` instead of empty string. * When adding a new workspace, the parent of the current workspace's current checkout will be checked out. That was always the intent, but the root commit was accidentally checked out instead. * When checking out a commit, the previous commit is no longer abandoned if it has a non-empty description. * All commands now consistently snapshot the working copy (it was missing from e.g. `jj undo` and `jj merge` before). ## [0.4.0] - 2022-04-02 ### Breaking changes * Dropped support for config in `~/.jjconfig`. Your configuration is now read from `/jj/config.toml`, where `` is `${XDG_CONFIG_HOME}` or `~/.config/` on Linux, `~/Library/Application Support/` on macOS, and `~\AppData\Roaming\` on Windows. ### New features * You can now set an environment variable called `$JJ_CONFIG` to a path to a config file. That will then be read instead of your regular config file. This is mostly intended for testing and scripts. * The [standard `$NO_COLOR` environment variable](https://no-color.org/) is now respected. * `jj new` now lets you specify a description with `--message/-m`. * When you check out a commit, the old commit no longer automatically gets abandoned if it's empty and has descendants, it only gets abandoned if it's empty and does not have descendants. * When undoing an earlier operation, any new commits on top of commits from the undone operation will be rebased away. For example, let's say you rebase commit A so it becomes a new commit A', and then you create commit B on top of A'. If you now undo the rebase operation, commit B will be rebased to be on top of A instead. The same logic is used if the repo was modified by concurrent operations (so if one operation added B on top of A, and one operation rebased A as A', then B would be automatically rebased on top of A'). See #111 for more examples. [#111](https://github.com/martinvonz/jj/issues/111) * `jj log` now accepts `-p`/`--patch` option. ### Fixed bugs * Fixed crash on `jj init --git-repo=.` (it almost always crashed). * When sharing the working copy with a Git repo, the automatic importing and exporting (sometimes?) didn't happen on Windows. ## [0.3.3] - 2022-03-16 No changes, only trying to get the automated build to work. ## [0.3.2] - 2022-03-16 No changes, only trying to get the automated build to work. ## [0.3.1] - 2022-03-13 ### Fixed bugs - Fixed crash when `core.excludesFile` pointed to nonexistent file, and made leading `~/` in that config expand to `$HOME/` [#131](https://github.com/martinvonz/jj/issues/131) ## [0.3.0] - 2022-03-12 Last release before this changelog started.
