Changes the formatter to accept not only existing color names (such as "red" or
"green") but also those in the form #rrggbb, where rr, gg, and bb are two-digit
hexadecimal numbers. This allows much finer control over colors used.
"-r REVISIONS" here specifies the search space of the branches to push, and
warned if no branches are found in that space. I don't think an empty set
should be an error, but a warning for consistency. The warning message will be
improved by the subsequent patches.
This command belongs to the same category as "duplicate".
We might want a plural version of resolve_revset(), but I'm not sure whether
it should return Vec<Commit> or Revset. Let's revisit it later when we get
more callers.
Suppose we have an alias 'immutable()' = '::immutable_heads()', user can
express (visible) mutable set as '~immutable()'. 'immutable_heads()..' can
terminate early, but a generic difference 'all() & ~immutable()' can't.
Suppose the generation value is usually small, it should be faster to do
bounded range look up first 'y-', then walk ancestors with the unwanted set
'y-..x'.
There's a subtle behavior change that an empty revset is no longer rejected
individually, but I think that's good for "jj duplicate".
cmd_duplicate() was the last caller of index.topo_order().
When an operation is missing and we recover the workspace, we create a
new working-copy commit on top of the desired working-copy commit (per
the available head operation). We then reset the working copy to an
empty tree because it shouldn't really matter much which commit we
reset to. However, when the workspace is sparse, it does matter, as
the test case from the previous patch shows. This patch fixes it by
replacing the `reset_to_empty()` method by a new `recover(&Commit)`,
which effectively resets to the empty tree and then resets to the
commit. That way, any subsequent snapshotting will result keep the
paths from that tree for paths outside the sparse patterns.
As shown by the updated test case, when we recover from a working copy
pointing to a lost operation, the new working-copy commit after
snapshotting will have lost any files outside the sparse patterns.
AST substitution is technically closer to parsing, but the parsed expression
can be modified further by caller. So I think it's better to do optimize() in
later pass.
revset_util::parse() is inlined.
Spotted while moving revset::optimize() around. Since we don't include the
parsing cost of the target expression, we shouldn't include parsing/evaluation
cost of the short-prefixes either. The IdPrefixContext is currently populated
by WorkspaceCommandHelper::new(), but it's hard to tell.
The original plan was to extend the globals table to implement "revset(expr)".
I'm not sure if that's more discoverable than "self.contained_in(revset_expr)"
method, but we can decide that later. Anyways, this patch adds typo suggestion
for global functions.
Prepares for migrating to table-based lookup. It's unlikely that the
implementor handles global function calls differently, but the core doesn't
have an access to the customized symbol table.
This is preparation for #3292, which will use these functions. The main
goal is to merge the parts of #3292 that are likely to cause merge
conflicts with other PRs while I polish it up.
This will be reused for integration with the new `:builtin-web` diff editor in #3292.
`instructions-path_to_cleanup` is moved into DiffWorkingCopies.
DiffWorkingCopies: add instructions_path_to_cleanup
This change updates the language of `jj edit`'s help message to be
more clear as to the nature of the command. It also adds a
recommendation for a more idiomatic/safer workflow.
I just wanted to remove CommandError from parse_immutable_expression(), which
will be called from the templater, but the new error message looks also better.
Some of them will be called directly from the commit templater which shouldn't
know WorkspaceCommandHelper. All parameters are passed as function arguments
instead of having a nicer wrapper struct. That's because some resources (e.g.
repo and id prefix context) are also used for different purposes, and it seemed
uneasy to introduce high-level abstraction satisfying all the use cases.
Now you can do e.g. `jj squash --from 'foo+::' --into foo` to squash a
whole series into one commit. It doesn't need to be linear; you can
squash a bunch of siblings into another siblings, for example.
Now as default and elided node symbols come from the config, the next logical
step is to use them directly bypassing GraphLog. Note that commands like `jj op
log` and `jj obslog` do not use the elided node symbol at all.
This was proposed by @Brixy in
https://github.com/martinvonz/jj/discussions/2882 a while ago. There
seems to be pretty strong consensus that it's a good idea.
I've copied the added test cases from `test_move_command.rs`, just
replacing `move` by `squash`, `--to` by `--into`, and deleting the
test of a no-arg invocation (`jj move` fails, `jj squash` does not -
it defaults to squashing into the parent).
This patch makes `jj squash` us the helper I just extracted from `jj
move`. I had a to add a few small features to it for that.
The `test_squash_command.rs` test changed in a few cases where we do a
partial squash. After this patch, we include the rebased child in the
count of rebased descendants. That seems reasonable and consistent
with partial squash/move further than 1 generation.
This is just a little step towards reusing the helper I just extracted
from `jj move`. I had to update `test_immutable_commits.rs` because it
would otherwise fail because of the merge rather than failing because
of the immutable commit.
I'm soon going to make `jj squash` accept either `-r` or
`--from/--to`, which means `-r` will then be optional. This patch
prepares for that already, since it also simplifies the code a little
(and improves it so we warn if the user does `jj squash -r @
nonexistent`).
This matches what we do for `jj squash`, whether it's a
full or partial move.
I didn't add a test since we're planning to deprecate `jj move`, and
this will soon be tested via the `jj squash` tests.
The `destination` variable we use when creating the operation log may
have been replaced earlier in the code. I think this was a regression
when I moved the setting of the description from `start_transaction()`
to `finish_transaction()` a while ago.
We haven't used custom Git commit headers for two main reasons:
1. I don't want commits created by jj to be different from any other
commits. I don't want Git projects to get annoyed by such commit
and reject them.
2. I've been concerned that tools don't know how to handle such
headers, perhaps even resulting in crashes.
The first argument doesn't apply to commits with conflicts because
such commits would never be accepted by a project whether or not they
use custom commit headers. The second argument is less relevant for
conflicted commits because most tools will be confused by such commits
anyway.
Storing conflict information in commit headers means that we can
transfer them via the regular Git wire protocol. We already include
the tree objects nested inside the root-level tree, so they will also
be transferred.
So, let's start by writing the information redundantly to the commit
header and to the existing storage. That way we can roll it back if we
realize there's a problem with using commit headers.
The `amend/unamend` aliases exist for smoothen onboarding for
Git/Mercurial users; I don't think we should recommend that users use
them, so I think it's fine if users override them as they
like. Therefore, I think they belong in the config.
This should address both use cases:
1. If from_relative_path() is directly called, the error says ".." shouldn't
be included in the (normalized) relative path.
2. If parse_fs_path() is used, the error message contains paths relative to
cwd. #3216
There's a caveat: "jj config list -Tname" will concatenate all names in a
single line. That's correct but useless. We might want some option or config
knob to complete missing "\n". This also applies to "log --no-graph".
This serves the role of the formatter in Mercurial, but the provided features
are rather restricted compared to mercurial.formatter. That's because both
implementation language "Rust" and jj's template language are statically typed.
The current implementation works well for simple commands like "config list -T",
but it might be not okay for "branch list -T". If we implement branch templating
by using the generic mechanism, the commit summary part would have to be
evaluated as a separate template:
-T 'branch_name ++ target_commit_summary' (target_commit_summary: Template)
instead of
-T 'branch_name ++ commit_summary(target_commit)' (target_commit: Commit)
where the branch template language is a superset of the commit template
language.
I'm going to add generic templating support for basic value types, and
"jj config list -T" will use CommandHelper::parse_template().
CommandHelper::load_template_aliases() is made private instead.
This will help deduplicate template parsing functions. We don't care about the
cost of config.get_string(), but I don't want to copy the config key to every
caller.
This could be a provided method of the TemplateLanguage trait, but it's
unlikely that this method would have to be customized by implementors. And
I'm going to add thin wrapper method to CommandHelper, so no users would
write language.parse(..) anyway.
I'm going to split commit/operation_templater::parse() into two parts, and
the first half will be Commit/OperationTemplateLanguage::new(..). This patch
also makes CommitTemplateLanguage::wrap_() functions public because extension
methods should be able to return property of these types.

This commit fixes the warnings by making the watchman URL a hyperlink and by
disabling the lint for the jj-cli error. Disabling the link is the right thing
to do because the comment is captured by clap and printed when `jj --help`
runs and any markdown formatting like `<>` is passed through.
The ExternalMergeTool struct has four 24-byte fields plus one bool. It could
be shrunk by dropping Vec/String capacity, but the resulting type would still
be bigger compared to the default Builtin variant.
I considered inlining tx.select_diff(), but that looked a bit cryptic because
the arguments orders are reasonably different. This thin wrapper will help
enforce the common interactive editing behavior.
This constructor has too many arguments enough to introduce a parameter struct,
which would be identical to the CommandHelper type. Let's simply inline it as
there are no external callers.
write!(ui.hint(), ..) error is suppressed because it seemed weird if the
configuration error had io::Error variant. The write error isn't important
anyway.
This moves the config loading closer to CLI args where --tool=<name> option
will be processed. The factory function are proxied through the command helper
so that the base_ignores can be attached there later.
I'm going to make them be loaded by caller, and these newtypes will provide
extra compile-time safety (plus nicer API to be added later.) The error types
will be cleaned up later patches.
This gets rid of the last UserSettings dependency from edit_diff_external().
I'm going to remove it from edit_diff() too, and let callers pass a
preconfigured MergeTool struct instead.
These changes will make it easier to add --tool=<name> argument #2575.
Because the snapshot directory is removed at the end of the function, it doesn't
make sense to enable watchman in it. The max_new_file_size parameter might be
somewhat useful, but it's unlikely that the temporary directory contains
gigantic node_modules tree for example. OTOH, the base_ignores matters since it
may contain common ignore patterns like *~.
This eliminates most of the UserSettings dependencies from this function.
I'm going to add string.len() method which will return a length in bytes. The
number of the UTF-8 code points is useless metrics, and strings here are often
ASCII bytes, so let's simply use byte indices in substr().
If the given index is not at a char boundary, it will be rounded. I considered
making it an error, but that would be annoying. I would want to see something
printed by author.name().substr() even if it contained latin characters.
I've extracted index normalization function which might be used by other string
methods. The remaining part of substr() is trivial, so inlined it.
Before, --tool=:builtin argument was ignored and the tool was loaded from
"ui.diff.tool" option. Since there is no single builtin diff format, :builtin
doesn't make sense here. Maybe we can translate ":<format>" to the internal
diff format instead, but that will also mean "ui.diff.tool" and ".format" can
be merged.
This partially reverts 409356fa5b "merge_tools: enable `:builtin` as default
diff/merge editor."
I'm going to split get_tool_config() to fix "diff --tool=:builtin", and it
doesn't make sense to duplicate get_tool_config_from_args() per backing
get_tool_config() functions.
This make :builtin render conflicts as conflict markers instead of
panicking. To support conflicts properly, we also need to parse the
conflict markers (calling `update_from_content()`) after the user
closes the editor.
A runtime error will be printed inline. This simplifies error handling, and I
think it's better behavior overall. "jj log" won't be terminated just because
"gpg" crashed during signature verification for example. When property
evaluation failed, the error propagates to the closest template expression, and
the error message is printed there. Then, template output continues as long as
the output stream is open.
If we add revset() function for example, dynamic revset evaluation error will be
displayed inline. Static revset expression will still be processed at parsing
phase (to cache the evaluation result), and the error will be reported early.
One caveat: a string argument passed to e.g. .contains(needle) can be a
template, so the evaluation error would be swallowed there.
It was moved to CLI at 42252a2f00 "cli: on `jj init --git-repo=.`, use
relative path to `.git/`." As far as I can tell, .canonicalize() is needed
to calculate relative path, which is now processed differently in
Workspace::init_external_git() and GitBackend::init_external().
This reverts dc074363d1 "no-op: Move external git repo canonicalization into
Workspace::init_git_external." As I said in the PR comment, appending ".git"
is normalization of the user input, which is IMHO more appropriate to be done
in the CLI layer.
The translation from method error to keyword error can go wrong if the context
object had n-ary methods (n > 0), which isn't the case as of now. For
simplicity, arguments error is mapped to "self.<name>(..)" suggestion.
Local variables and "self" could be merged without using extra method, but
we'll need extend_*_candidates() to merge in symbol/function aliases anyway.
This seems more useful if aliases are nested. The innermost error usually
contains the problem, and the outer errors are contexts where aliases are
expanded.
Except for the generic list and template methods. We'll need a bit more
refactoring to migrate List<T> method builders to be compatible with
non-capturing fn() type.
The recovery commit we create when we run into a stale working copy
with a missing operation currently has an empty tree. Our commit
backend at Google creates an index of which files changed in each
commit. That gets really expensive when a commit deletes all files in
the repo, as these recovery commits do. So for our backend, it is much
better to make the recovery commit empty instead. That's what this
patch does.
It almost doesn't matter functionally what tree we use for it since we
don't care much about the current tree when snapshotting the working
copy. It does matter in a few cases, however. One case is for
conflicts. In that case, it's likely better to use the recovery
commit's parent as base tree (as we do by making the recovery commit
empty) than to use an empty tree, as that would guarantee that all
conflicts would be considered resolved. (Side note: perhaps we should
start looking at the current commit's parent instead of looking at the
current commit when snapshotting, but that's a topic for another day.)
When we abandon a working-copy commit, we create a new working-copy
commit on top. This behave is very useful, but it's not obvious. Let's
document it.
Thankfully, 2bbefcc338 (rewrite: default to not simplifying ancestor
merges) means that there are much fewer commands where we need to
document this behavior.
