We are a little weird about which string escapes we support, and we don't
support raw strings. I thought this might be worth documenting.

Thanks to @lazywei for pointing out that `git pack-refs --all` is better, at
least on the first run. I haven't checked, but suspect, that because of the
number of `refs/jj` refs jj creates, it might always be better.
This is essentially a new version, which clarifies multiple statements about
`jj run`. Notably, it cleans up some mistakes which were overlooked or deemed
good enough in the Google Docs version.
This ticks another box in #1869.

https://github.com/martinvonz/jj/discussions/2230 indicates a lot of
interest in this, so we'd probably want to support this officially at
some point. Until then, document a script that has worked well-enough
for some of us.
I think the feature is requested by enough users that we should
include it by default, also for people who install from source (we
include it in the `packaging` feature already).
It increases the size of the binary from 16.5 MiB to 17.8 MiB. I
suspect we'd see some of that increase in size soon anyway, as I'm
probably going to use Tokio for making async backend requests.
Suppose "x::y" is the operator that defaults to "root()::visible_heads()"
respectively, "::" is identical to "all()". Since we've just changed the
behavior of "..y", ".." is now "root()..visible_heads()" meaning "~root()".
One action publishes the 'prerelease' version on every push
to `main`.
The other publishes a 'latest' version on every releasse.
I tested both of them, but not with branch protection rules.
I initially was thinking of using `mdbook`, which looks a little better, but I
think versioning the docs is important, and the features I want are pretty much
only supported by the Mkdocs' "Material" theme.
Mkdocs is written in Python. The prerequesites for building docs on your
machine should be to install Python and Poetry, everything else should be
installed automatically by Poetry. See the edits to `contributing.md` for more details.
This allows the tutorial to reference them and will make it
easier to have different instructions for different versions.
We can later restore some instructions to the README, but I
think this is important since the installation instructions
do change in important (even if slight) ways from time to
time.
`vimtabdiff` has a few potential advantages:
- It can be much more convenient for diffs with few files
- It can be easier to set up for some people (it is a Python script rather
than a Vim plugin).
- The author accepts patches, and I hope to make it support 3-pane diff.
The pros and cons are also described in the linked Gist.
Per discussion in #2107, I believe "exact" is preferred.
We can also change the default to exact match, but it doesn't always make
sense. Exact match would be useful for branches(), but not for description().
We could define default per predicate function, but I'm pretty sure I cannot
remember which one is which.
git-branchless calls it a substring, so let's do the same.
FWIW, I copied literal:_ from Mercurial, but it's exact:_ in git-branchless.
I have no idea which one is preferred. Since this feature isn't released, we
can freely change it if exact:_ makes more sense.
https://github.com/arxanas/git-branchless/wiki/Reference:-Revsets#patterns
The syntax is slightly different from Mercurial. In Mercurial, a pattern must
be quoted like "<kind>:<needle>". In JJ, <kind> is a separate parsing node, and
it must not appear in a quoted string. This allows us to report unknown prefix
as an error.
There's another subtle behavior difference. In Mercurial, branch(unknown) is
an error, whereas our branches(literal:unknown) is resolved to an empty set.
I think erroring out doesn't make sense for JJ since branches() by default
performs substring matching, so its behavior is more like a filter.
The parser abuses DAG range syntax for now. It can be rewritten once we remove
the deprecated x:y range syntax.
Similar to other boolean flags, such as "working_copy" or "empty".
We could test something like
`"0000000000000000000000000000000000000000".contains(commit_id)`
like I did for myself, but first of all this is ugly, and secondly the root
commit id is not guaranteed to be 40 zeroes as custom backend implementations
could have some other root.
That is, jj will use ui.default_description as a starting point when
user is about to describe an empty change.
I think it might be confusing to do this with -m / --stdin (violates
WYSIWYG), so I'm only doing this when jj invokes an editor.
Also, this could evolve into a proper template in the future instead of
just plain text, to allow inheriting from parent change(s), for example.
Partially addresses #1354.
This makes it possible to use ed25519 and ed25519-sk keys by trying
them one at a time. However, it still fails if one of them is
password-protected; we don't try the next key in that case.
This could be a "ui.diff.format" variant, but we would need to solve namespace
problem by prefixing "tool:<name>" for example. Then, inlining command arguments
would become uglier.
#1886
This is basic implementation. There's no config knob to enable the external
diff command by default. It reuses the merge-tools table because that's how
external diff/merge commands are currently configured. We might want to
reorganize them in #1285.
If you run "jj diff --tool meld", GUI diff will open and jj will wait for
meld to quit. This also applies to "jj log -p". The "diff --tool gui" behavior
is somewhat useful, but "log -p --tool gui" wouldn't. We might want some flag
to mark the tool output can't be streamed.
Another thing to consider is tools that can't generate directory diffs. Git
executes ext-diff tool per file, but we don't. Difftastic can compare
directories, and doing that should be more efficient since diffs can be
computed in parallel (at the expense of unsorted output.)
Closes#1886
The `--allow-large-revsets` flag we have on `jj rebase` and `jj new`
allows the user to do e.g. `jj rebase --allow-large-revsets -b
main.. -d main` to rebase all commits that are not in main onto
main. The reason we don't allow these revsets to resolve to multiple
commits by default is that we think users might specify multiple
commits by mistake. That's probably not much of a problem with `jj
rebase -b` (maybe we should always allow that to resolve to multiple
commits), but the user might want to know if `jj rebase -d @-`
resolves to multiple commits.
One problem with having a flag to allow multiple commits is that it
needs to be added to every command where we want to allow multiple
commits but default to one. Also, it should probably apply to each
revset argument those commands take. For example, even if the user
meant `-b main..` to resolve to multiple commits, they might not have
meant `-d main` to resolve to multiple commits (which it will in case
of a conflicted branch), so we might want separate
`--allow-large-revsets-in-destination` and
`--allow-large-revsets-in-source`, which gets quite cumbersome. It
seems better to have some syntax in the individual revsets for saying
that multiple commits are allowed.
One proposal I had was to use a `multiple()` revset function which
would have no effect in general but would be used as a marker if used
at the top level (e.g. `jj rebase -d 'multiple(@-)'`). After some
discussion on the PR adding that function (#1911), it seems that the
consensus is to instead use a prefix like `many:` or `all:`. That
avoids the problem with having a function that has no effect unless
it's used at the top level (`jj rebase -d 'multiple(x)|y'` would have
no effect).
Since we already have the `:` operator for DAG ranges, we need to
change it to make room for `many:`/`all:` syntax. This commit starts
that by allowing both `:` and `::`.
I have tried to update the documentation in this commit to either
mention both forms, or just the new and preferred `::` form. However,
it's useless to search for `:` in Rust code, so I'm sure I've missed
many instances. We'll have to address those as we notice them. I'll
let most tests use `:` until we deprecate it or delete it.
Summary: This was some fallout from merging #1851; I missed a few changes
I needed to back out for an upcoming diff.

Summary: Let's be more aggressive about tracking the latest stable Rust release.
There's little benefit to being conservative so early on, especially when no
users seem to have faced any issue with upgrading, or strictly required an old
Rust version.
Right now, just lagging Rust by 1 major release probably seems fine. We're
targeting 1.71.0 to get ahead of the curve, since 1.72.0 will likely release
sometime before the next `jj` release.

Almost everyone calls the project "jj", and there seeems to be
consensus that we should rename the crates. I originally wanted the
crates to be called `jj` and `jj-lib`, but `jj` was already
taken. `jj-cli` is probably at least as good for it anyway.
Once we've published a 0.8.0 under the new names, we'll release 0.7.1
versions under the old names with pointers to the new crates names.
This bug concerns the way `import_refs` that gets called by `fetch` computes
the heads that should be visible after the import.
Previously, the list of such heads was computed *before* local branches were
updated based on changes to the remote branches. So, commits that should have
been abandoned based on this update of the local branches weren't properly
abandoned.
Now, `import_refs` tracks the heads that need to be visible because of some ref
in a mapping keyed by the ref. If the ref moves or is deleted, the
corresponding heads are updated.
Fixes#864
This adds a config called `revsets.short-prefixes`, which lets the
user specify a revset in which to disambiguate otherwise ambiguous
change/commit ids. It defaults to the value of `revsets.log`.
I made it so you can disable the feature by setting
`revsets.short-prefixes = ""`. I don't like that the default value
(using `revsets.log`) cannot be configured explicitly by the
user. That will be addressed if we decide to merge the `[revsets]` and
`[revset-aliases]` sections some day.
I plan to add `revsets.short-prefixes` and `revsets.immutable` soon,
and I think `[revsets]` seems like reasonable place to put them. It
seems consistent with our `[templates]` section. However, it also
suffers from the same problem as that section, which is that the
difference between `[templates]` and `[template-aliases]` is not
clear. We can decide about about templates and revsets later.
IIUC, the consensus in the Git project is that the overloaded nature
of `git checkout` for many use cases was a mistake, and `git
switch/restore` are meant to replace it.
We currently say that `x..y` is "Ancestors of `y` that are not also
ancestors of `x`, both inclusive.". However, it's easy to think that
"both inclusive" means that both `x` and `y` are included in the set,
which is not the case. What we mean is more like "{Ancestors of `y`,
including `y` itself} that are not also {ancestors of `x`, including
`x` itself}.". Given that we already define ancestors and descendants
as being inclusive on the lines above, and we also give the equivalent
expressions using the `x:` and `:y` operators, it's probably best to
just skip the "both inclusive" parts.
This doc describes what we need to consider in a submodule storage
solution, some possible solutions and what criteria we should use to
decide on a future direction.
This is still a WIP:
- The solutions are still underdescribed
- The actual evaluation of solutions is missing
Suggestions for the above are welcome :)
The need for a glossary came up on Discord today.
This needs some more work, but I think this is a good start. I'm still
happy to update it if anyone has suggestions, of course. I haven't
started sprinkling pointers to the glossary from other places, so
users will only discover it by browsing the `docs/` directory.
This is a convenience optimization to improve the default user
experience, since `jj log` is a frequently run command. Accessing the
help information explicitly still follows normal CLI conventions, and
instructions are displayed appropriately if the user happens to make a
mistake. Discoverability should not be adversely harmed.
Note that this behavior mirrors what Sapling does [2], where `sl` will
display the smartlog by default.

The `heads()` revset function with one argument is the counterpart to
`roots()`. Without arguments, it returns the visible heads in the
repo, i.e. `heads(all())`. The two use cases are quite different, and
I think it would be good to clarify that the no-arg form returns the
visible heads, so let's split that out to a new `visible_heads()`
function.
This document is meant to be a record of how we think about Git
submodules (and not a _current_ implementation of submodules). We will
fill it out incrementally as we get a clearer idea of what we want
submodules to look like.
As an initial version, I started with (IMO) the least controversial
points:
- We want to support most workflows Git submodules users are accustomed
to.
- A roadmap that allows us to incrementally roll out Git submodule
functionality (instead of having to boil the ocean).
This serves the role of limit() in Mercurial. Since revsets in JJ is
(conceptually) an unordered set, a "limit" predicate should define its
ordering criteria. That's why the added predicate is named as "latest".
Closes#1110
We need 1.64 to bump `clap` to `4.1`. We don't really need to upgrade
to that, but being on an older version causes minor confusions like
#1393. Rust 1.64 is very close to 6 months old at this point.
This involves a little hack to insert a lambda parameter 'x' to be used at
keyword position. If the template language were dynamically typed (and were
interpreted), .map() implementation would be simpler. I considered that, but
interpreter version has its own warts (late error reporting, uneasy to cache
static object, etc.), and I don't think the current template engine is
complex enough to rewrite from scratch.
.map() returns template, which can't be join()-ed. This will be fixed later.
@joyously found `o` confusing because it's a valid change id prefix. I
don't have much preference, but `●` seems fine. The "ascii",
"ascii-large", and "legacy" graph styles still use "o".
I didn't change `@` since it seems useful to have that match the
symbol used on the CLI. I don't think we want to have users do
something like `jj co ◎-`.
Unlike Mercurial, this isn't a template keyword/function, but a config knob.
Exposing graph_width to templater wouldn't be easy, and I don't think it's
better to handle terminal wrapping in template.
I'm not sure if patch content should be wrapped, so this option only applies
to the template output for now.
Closes#1043
The parameter order follows indent()/label() functions, but this might be
a bad idea because fill() is more likely to have optional parameters. We can
instead add template.fill(width) method as well as .indent(prefix). If we take
this approach, we'll probably need to add string.fill()/indent() methods,
and/or implicit cast at method resolution. The good thing about the method
syntax is that we can add string.refill(), etc. for free, without inventing
generic labeled template functions.
For #1043, I think it's better to add a config like ui.log-word-wrap = true.
We could add term_width/graph_width keywords to the templater, but the
implementation would be more complicated, and is difficult to use for the
basic use case. Unlike Mercurial, our templater doesn't have a context map
to override the graph_width stub.
A list type isn't so useful without a map operation, but List<CommitId>
is at least printable. Maybe we can experiment with it to craft a map
operation.
If a map operation is introduced, this keyword might be replaced with
"parents.map(|commit| commit.commit_id)", where parents is of List<Commit>
type, and the .map() method will probably return List<Template>.
The argument order is different from Mercurial's indent() function. I think
indent(prefix, content) is more readable for lengthy content. However,
indent(content, prefix, ...) might be better if we want to add an optional
firstline_prefix argument.
This eliminates ambiguous parsing between "func()" and "expr ()".
I chose "++" as template concatenation operator in case we want to add
bit-wise negate operator. It's also easier to find/replace than "~".
The outermost "op-log" label isn't moved to the default template. I think
it belongs to the command's formatter rather than the template.
Old bikeshedding items:
- "current_head", "is_head", or "is_head_op"
=> renamed to "current_operation"
- "templates.op-log" vs "templates.op_log" (the whole template is labeled
as "op-log")
=> renamed to "op_log"
- "template-aliases.'format_operation_duration(time_range)'"
=> renamed to 'format_time_range(time_range)'
Now that we use headers to define `[template-aliases]`, I thought we should explain how they are also equivalent to dotted keys.
Alternatively, we could rewrite them all in the dotted style, but it would look awkward.
I'm going to remove the corresponding config knobs.
As an example of "brackets" short id, I put a simplified version. It's
unlikely that the "rest()" gets empty for hashes of 12-char long.
We have made some changes to CLI output that had not made it into the
tutorial. It's time to update it, especially with the new change id
rendering. Since I'm updating it now, and since it's a bit of work to
do so, I decided to use GitHub's Hello-World repo instead of jj's own
repo as our example.
Supported values are,
- `none` for no author information,
- `full` for both the name and email,
- `name` for just the name,
- `username` for username part of the email,
- (default) `email` (or any other gibberish for that matter) for the full email.
For stock merge-tools, having name -> args indirection makes sense. For
user-specific settings, it's simpler to set command name and arguments
together.
It might be a bit odd that "name with whitespace" can be parsed differently
depending on the existence of merge-tools."name with whitespace".
I keep calling it `underline` by mistake, so that probably means that
it's a more natural name for it. We haven't made a release of it yet,
so I didn't mention it in the changelog.
I didn't update all variables to also use `underline`, because I felt
that `underlined` was usually more natural there, plus crossterm calls
it `Attribute::Underlined`.
Add a new git.auto-local-branch config option. When set to false, a
remote-tracking branch imported from Git will not automatically create a
local branch target. This is implemented by a new GitSettings struct
that passes Git-related settings from UserSettings.
This behavior is particularly useful in a co-located jj and Git repo,
because a Git remote might have branches that are not of everyday
interest to the user, so it does not make sense to export them as local
branches in Git. E.g. https://github.com/gitster/git, the maintainer's
fork of Git, has 379 branches, most of which are topic branches kept
around for historical reasons, and Git developers wouldn't be expected
to have local branches for each remote-tracking branch.
I think of it more as style than a format, so using `style` in the
config key makes sense to me.
I didn't bother making upgrades easy by supporting the old name since
this was just released and only a few developers probably have it set.
The heading says it's going to explain aliases, but it doesn't, and
now that we've documented aliases in config.md, we probably don't need
to mention it in the tutorial.
The `git.fetch` and `git.push` keys can be used in the configuration file
for the default to use in `jj git fetch` and `jj git push` operations.
By defaut, "origin" is used in both cases.
- branches has the signature branches([needle]), meaning the needle is optional (branches() is equivalent to branches("")) and it matches all branches whose name contains needle as a substring
- remote_branches has the signature remote_branches([branch_needle[, remote_needle]]), meaning it can be called with no arguments, or one argument (in which case, it's similar to branches), or two arguments where the first argument matches branch names and the second argument matches remote names (similar to branches, remote_branches(), remote_branches("") and remote_branches("", "") are all equivalent)
Running `cargo fmt` while you're working in an editor means that you
may lose changes because of a race:
1. Your editor reads version X of file
2. `cargo fmt` reads version X
3. You save version Y from your editor
4. `cargo fmt` saves version Z, replacing Y
Since per-repo config may contain CLI settings, it must be visible to CLI.
Therefore, UserSettings::with_repo() -> RepoSettings isn't used, and its
implementation is nullified by this commit.
#616
After I changed `merge-tools.vimdiff.program` to `vim`, using
`vimdiff` as a diff editor wouldn't work at all.
Out of the box, it's still not a good experience. I included a
recommendation of a plugin to install to make it better.
It can be confusing that the lib crate is not tested when you run
`cargo test` without `--workspace` from the root directory. Also,
`nextest` is a non-obvious quality-of-life improvement, so let's
suggest that.
When importing `conflicts.md` into the Google repo, our internal tools
complained that it contained conflict markers. Similarly, if you ever
get an actual merge conflict in the file, the working-copy
snapshotting would parse our sample conflict markers here, forcing you
to work around it. Let's avoid that by indenting the conflict
markers. Hopefully readers will understand that the leading space is
not part of the markers.
When a workspace's working-copy commit is updated from another
workspace, the workspace becomes "stale". That means that the working
copy on disk doesn't represent the commit that the repo's view says it
should. In this state, we currently automatically it to the desired
commit next time the user runs any command in the workspace. That can
be undesirable e.g. if the user had a slow build or test run started
in the working copy. It can also be surprising that a checkout happens
when the user ran a seemingly readonly command like `jj status`.
This patch makes most commands instead error out if the working copy
is stale, and adds a `jj workspace update-stale` to update it. The
user can still run commands with `--no-commit-working-copy` in this
state (doing e.g. `jj --no-commit-working-copy rebase -r @ -d @--` is
another way of getting into the stale-working-copy state, by the way).
As dbarnett@ reported on #9, our default of `less`, combined with our
default of enabling color on TTYs, means that we print ANSI codes to
`less` by default. Unless the user has set e.g. `$LESS=R`, `less` is
going to escape those codes, resulting in garbage like this:
```
@ ESC[1;35mbb39c26a29feESC[0m ESC[1;33m(no email configured)ESC[0m ESC[1;36m2022-12-03....
```
I guess most of us didn't notice because we have something like
`$LESS=FRX` set.
This patch changes our default from `less` to `less -FRX`. Those are
the flags we're using for our internal hg distribution at Google, and
that has seemed quite uncontroversial.
I added a pointer from the changelog to the tracking issue while at
it.
It should be more reliable than parsing a command string into array.
Also updated some of the doc example to use array syntax. I don't think
"C:/Program Files" was parsed properly, but might work thanks to Windows
magic.
Teach Ui's writing functions to write to a pager without touching the
process's file descriptors. This is done by introducing UiOutput::Paged,
which spawns a pager that Ui's functions can write to.
The pager program can be chosen via `ui.pager`. (defaults to Defaults to
$PAGER, and 'less' if that is unset (falling back to 'less' also makes
the tests pass).
Currently, commands are paginated if:
- they have "long" output (as defined by jj developers)
- jj is invoked in a terminal
The next commit will allow pagination to be turned off via a CLI option.
More complex pagination toggling (e.g. showing a pager even if the
output doesn't look like a terminal, using a pager for shorter ouput) is
left for a future PR.
Because a unary negation node '~y' is more primitive than the corresponding
difference node 'x~y', '~y' is easier to deal with while rewriting the tree.
That's the main reason to add RevsetExpression::NotIn node.
As we have a NotIn node, it makes sense to add an operator for that. This
patch reuses '~' token, which I feel intuitive since the other set operators
looks like bitwise ops. Another option is '!'.
The unary '~' operator has the highest precedence among the set operators,
but they are lower than the ranges. This might be counter intuitive, but
useful because a prefix range ':x' can be negated without parens.
Maybe we can remove the redundant infix operator 'x ~ y', but it isn't
decided yet.
Function parameters are processed as local symbols while substituting
alias expression. This isn't as efficient as Mercurial which caches
a tree of fully-expanded function template, but that wouldn't matter in
practice.
Because the use of the change id is recommended, any operation should abort
if a valid change id happens to match a commit id. We still try the commit
id lookup first as the change id lookup is more costly.
Ambiguous change/commit id is reported as AmbiguousCommitIdPrefix for now.
Maybe we can merge AmbiguousCommit/ChangeIdPrefix errors into one?
Closes#799
Aliases are loaded at WorkspaceCommandHelper::new() as it's easier to warn
invalid declarations there. Not all commands use revsets, but many do, so
I think it's okay to always pay the loading cost. Parsing the declaration
part (i.e. a symbol) should be fast anyway.
The nested error message isn't super readable, but seems good enough.
Config syntax to bikeshed:
- naming: [revset-alias] vs [revset-aliases] ?
- function alias will need quotes: 'f(x)' = 'x'
The expression 'x ~ empty()' is identical to 'x & file(".")', but more
intuitive.
Note that 'x ~ empty()' is slower than 'x & file(".")' since the negative
intersection isn't optimized right now. I think that can be handled as
follows: 'x ~ filter(f)' -> 'x & filter(!f)' -> 'filter(!f, x)'
We have talked about showing the commit ID only for divergent changes
because it's generally easier to work with the change ID, and it's
less likely to result in a divergent change. However, it's useful to
have the commit ID available for pasting into e.g. a commit message or
the GitHub UI. To try to steer users towards using the change ID, this
commit moves the commit ID off to the right in the log output.
I put it just after the "divergent" field, because that makes it close
to how I imagine it would look if we decided to hide the commit ID
except for divergent changes. I was thinking that could be rendered as
"divergent (abc123)". So if we add config to hide the commit ID, then
it would be rendered almost the same for divergent commits (just with
the added parentheses). It would also make sense to replace the
"divergent" field by a question mark on the change ID, since change
IDs basically behave like branches. If we do that, then the placement
of the commit ID I picked in this commit does not make sense.
Given how easy this was, I can't believe I didn't make the change
sooner.
I haven't updated the screenshots in the readme because I plan to make
some further changes to the default template. I'll update them after
those changes.
It's useful to know when you've modified a branch that exists on a
remote. A typical case is when you have pushed a branch to a remote
and then rewritten it. This commit adds an indication in the
`branches` template keyword. A branch that needs to be pushed to a
remote now has a `*` at the end (similar to how conflicted branches
have a `?` at the end). Note that the indication only considers
remotes where the branch currently exists, so there won't be an
indication that the branch has not been pushed to a remote.
Closes#254
Unfortunately, TOML requires quotes around the argument. So, the
usage is `jj --config-toml ui.color=\"always\"` in bash. The plan is
to eventually have a `--config` option with simpler syntax for
simple cases.
As discussed in https://github.com/martinvonz/jj/discussions/688.
Since 'merges()' just filters the candidates set per item, it doesn't need
a candidates argument. Perhaps, 'merges(x)' could be a predicate to select
merge commits within a subgraph 'x', but I don't know if that would be
useful.
I feel the original -------/+++++++ pair is slightly confusing because
each half can be a separator by itself. I don't know what character other
than '-'/'+' is preferred, but let's pick '%' (for "mod") per @martinvonz
suggestion.
We have supported multiple workspaces for six months now, but I forgot
to remove a note in the revset doc saying that we don't support
it. Also update the text to descibe how to refer to the working-copy
commit in another workspace.
We have had support for workspaces for six months, but I forgot to

This just adds some basic documentation; we can add more later.
Since we now allow pushing open commits, we can implement support for
pushing the "current" branch by defining a "current" branch as any
branch pointing to `@`. That definition of a current/active seems to
have been the consensus in discussion #411.
Closes#246.
Sturdy came up a while ago on lobste.rs when [jj was being discussed](https://lobste.rs/s/47zztj/jujutsu_dvcs). I'm not sure if I described it well, or if it's something you want as related-work, especially since the sturdy founder claims to be solving different problems in the very thread. But it does seem to be doing some similar things to removing the idea of an index/staging area.
It can be confusing that some commits (typically the working copy)
don't have a description. Let's show a placeholder text in such cases.
I chose the format to match the "(no email configured)" message we
already have.
The default log output of showing all commits is not very useful when
contributing to an existing repo. Let's have it default to showing
commits not on any remote branch instead. I think that's the best we
can do since we don't have a configurable main branch yet, and we
don't even have per-repo configuration..
Closes#250.
It's much easier to tell users on all platforms to put their config in
`~/.jjconfig.toml` than in a path that varies across the platforms, so
let's do that. It also seems like a less controversial location for
the file.
Closes ##233.
This adds a `jj sparse` command with options to list and manage the
set of paths to include in the working copy. It only supports includes
(postive matches) for now.
I'm not sure "sparse" is the best name for the feature. Perhaps it
would make sense as a subcommand under `jj workspace` - maybe `jj
workspace track`? However, there's also `jj untrack` for removing a
file from the working copy and leaving it in the working copy. I'm
happy to hear suggestions, or we can get back to the naming later.
This introduces a `connected(x)` function, which is simply the same as
`x:x`. It's occasionally useful if `x` is a long expression. It's also
useful as a building block for `root(x)` (coming soon).
I'm a little hesitant to do this because most tools I'm familiar with
have the config file directly in `~/`. It's also easier to describe
where to put the file if it doesn't vary across platforms. But we're
still early in the project, so let's try it and see if we get any
complaints.
It probably doesn't make sense to respect Git's `core.excludesFile`
config when not running in a Git-backed repo, but we also already
respect `.gitignore` files in the working copy regardless of backend,
so at least it's consistent with that. We can revisit it when the
native backend becomes a reasonable choice.
Closes#87.
We used to have documention about how conflicts are implemented, but I
removed that a long time ago when I rewrote the README to target users
rather than VCS hackers. Let's have a doc for the VCS hackers (and
curious users) as well, though.
