I think we should test actually performing the push when possible. I
think I initially used `--dry-run` because I thought it wasn't
possible to do local pushes with libgit2.
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.

I wasn't quite happy with `jj support` but I couldn't think of
anything better when I moved the commands from `jj debug` in
e2b4d7058d. Thanks to @ilyagr for suggesting `jj util`.
This makes it clear what should be resolved at resolve_symbols(). Symbol
is a bit special while parsing function arguments, but it's no different
than the other unresolved references at expression level.
This changes the version number reported by `jj version` from "0.7.0"
to something like
"0.7.0-24a512683bc921699575b6a953624b05c068d544a". The hash is added
if running in a jj repo or a git repo.
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.
The impact of not having configured one's name and email is not apparent from the warning message. Under the Toulmin model:
- Claim (implicit): You should configure your name and email.
- Grounds: Your name and email are not currently configured.
- Warrant (currently missing): Configuring your name and email will let you do...
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
I think requests to reset the author came up twice in the last week,
so let's just add support for it. I copied git's behavior of resetting
the name, email, and timestamp. The flag name is also from git.
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.
A lambda expression will be allowed only in .map() operation. The syntax is
borrowed from Rust closure.
In Mercurial, a map operation is implemented by context substitution. For
example, 'parents % "{node}"' prints parents[i].node for each. There are two
major problems: 1. the top-level context cannot be referred from the inner map
expression. 2. context of different types inserts arbitrarily-named keywords
(e.g. a dict type inserts "{key}" and "{value}", but how we could know.)
These issues should be avoided by using explicitly named parameters.
parents.map(|parent| parent.commit_id ++ " " ++ commit_id)
^^^^^^^^^ global keyword
A downside is that we can't reuse template fragment in map expression. Suppose
we have -T commit_summary, -T 'parents.map(commit_summary)' doesn't work.
# only usable as a top-level template
'commit_summary' = 'commit_id.short() ++ " " ++ description.first_line()'
Another problem is that a lambda expression might be confused with an alias
function.
# .map(f) doesn't work, but .map(g) does
'f(x)' = 'x'
'g' = '|x| x'
The `jj debug` commands are hidden from help and are described as
"Low-level commands not intended for users", but e.g. `jj debug
completion` is intended for users, and should be visible in the help
output.
By using one letter for the path type before and one letter for path
type after, we can encode much more information than just the current
'M'/'A'/'R'. In particular, we can indicate new and resolved
conflicts. The color still encodes the same information as before. The
output looks a bit weird after many years of using `hg status`. It's a
bit more similar to the `git status -s` format with one letter for the
index and one with the working copy. Will we get used to it and find
it useful?
I'm going to add a lambda expression, and the current type-error message
wouldn't work for the lambda type. I also renamed "argument" to "expression"
as the expect_<type>() helper may be called against any expression node.
This is similar to the structure of RevsetParseError. It's unlikely we would
need to discriminate parsing errors, so let's avoid wasting time on naming
things.
@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 ◎-`.
I broke the commands in a27da7d8d5 and thought I just fixed it in
c7cf914694a8. However, as I added a test, I realized that I made it
only reindex the commits since the previous operation. I meant for the
command to do a full reindexing of th repo. This fixes that.
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 "~".
Since there's no easy API to snapshot the stale working copy without releasing
the lock, we have to compare the tree ids after reacquiring the lock. We could
instead manually snapshot and rebase the working-copy commit, but that would
require more copy-paste codes.
Closes#1310
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)'
We write conflict to the working copy by materializing them as
conflict markers in a file. When the file has been modified (or just
the mtime has changed), we parse the markers to reconstruct the
conflict. For example, let's say we see this conflict marker:
```
<<<<<<<
+++++++
b
%%%%%%%
-a
+c
>>>>>>>
```
Then we will create a hunk with ["a"] as removed and ["b", "c"] as
added.
Now, since commit b84be06c08, when we materialize conflicts, we
minimize the diff part of the marker (the `%%%%%%%` part). The problem
is that that minimization may result in a different order of the
positive conflict terms. That's particularly bad because we do the
minimization per hunk, so we can end up reconstructing an input that
never existed.
This commit fixes the bug by only considering the next add and the one
after that, and emitting either only the first with `%%%%%%%`, or both
of them, with the first one in `++++++++` and the second one in
`%%%%%%%`.
Note that the recent fix to add context to modify/delete conflicts
means that when we parse modified such conflicts, we'll always
consider them resolved, since the expected adds/removes we pass will
not match what's actually in the file. That doesn't seem so bad, and
it's not obvious what the fix should be, so I'll leave that for later.
When we materialize modify/delete conflicts, we currently don't
include any context lines. That's because modify/delete conflicts have
only two sides, so there's no common base to compare to. Hunks that
are unchanged on the "modify" side are therefore not considered
conflicting, and since they they don't contribute new changes, they're
simply skipped (here:
3dfedf5814/lib/src/files.rs (L228-L230)).
It seems more useful to instead pretend that the missing side is an
empty file. That way we'll get a conflict in the entire file.
We can still decide later to make e.g. `jj resolve` prompt the user on
modify/delete conflicts just like `hg resolve` does (or maybe it
actually happens earlier there, I don't remember).
Closes#1244.
Since type/name checking is made after alias substitution, we need to preserve
the original context to generate a readable error message.
We could instead attach a stack of (alias_id, span) to ExpressionNode, but
the extra AliasExpanded node helps to capture downstream error by a single
.map_err() call.
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.
The added expect_arguments() is basically a copy from the template_parser.
I'll reimplement it to support keyword arguments, so I don't care much about
the current implementation.
I leave expect_no/one_argument() as wrappers because parsing 0/1 arguments
is pretty common.
Error messages are slightly changed. I personally prefer not to add extra
code for singular/plural handling, but if we do, I'll add 'if N == 1' case.
The unique-prefixe tests are typically the slowest tests. Here's the
end of my `cargo nextest --workspace` output (from an arbitrary run,
not best-of-5 or anything):
PASS [ 5.129s] jujutsu::test_log_command test_log_prefix_highlight_brackets
PASS [ 5.220s] jujutsu::test_log_command test_log_prefix_highlight_styled
PASS [ 8.523s] jujutsu::test_log_command test_log_prefix_highlight_counts_hidden_commits
These tests create 50-100 commits in a loop. I think much of it comes
from the subprocessing and/or the repeated loading of the repository
in the subprocesses. Rewriting them to use `jj duplicate` for creating
many commits at once speeds them up. Here are the timings after:
PASS [ 2.323s] jujutsu::test_log_command test_log_prefix_highlight_styled
PASS [ 2.330s] jujutsu::test_log_command test_log_prefix_highlight_brackets
PASS [ 3.773s] jujutsu::test_log_command test_log_prefix_highlight_counts_hidden_commits
I felt that the config is too narrow to have it's own top-level [diff]
section, and I couldn't think of another good place to have it. I'm
happy to hear other suggestions.
