This patch does not change the handling of inline tables yet. Both inline and
non-inline tables are merged as before. OTOH, .set_value() is strict about table
types because it should refuse to overwrite a table whereas an inline table
should be overwritten as a value. This matches "jj config set"/"unset"
semantics. rules_from_config() in formatter.rs uses .as_inline_table(), which is
valid because toml_edit::Value type never contains non-inline table.
Since toml_edit::Value doesn't implement PartialEq, stacking tests now use
insta::assert_snapshot!().
I think the idea of the code was try do 30 updates per second even if
events arrive at, say, every 20 milliseconds. If we had reset the
timer every time we printed, we would otherwise reset the timer every
40 milliseconds and end up with 25 updates per second. However, a bug
in the code caused it to print every update because it always set the
threshold to print the next update to `now`. I tried to keep what I
think was the intent of the original code while fixing the bug.
The progress bar is supposed to update only 30 times per second, but
as was reported in #5057, that doesn't seem to be what's
happening. This patch adds tests showing how we update the progress
bar for every event.
Both Mercurial and Git (xdiff) have a special case for empty hunks.

I also changed the internal line numbers to start from 0 so we wouldn't have
to think about whether "N - 1" would underflow.
Fixes#5049
Appears that "cargo test" parses indented text as a code block, and fails to
run doc tests. Spotted by running "cargo insta test". This doc comment is a CLI
help which is usually rendered to console, so I think markdown annotation should
be minimal.
This backs out commit ed84468cb8f3, "docs: in `jj help util exec`, use Markdown
`warning` admonition."
Since config::Value type was lax about data types, an integer value could be
deserialized through a string. This won't apply to new toml_edit-based value
types.
We're scraping the CLI help text and rendering it as markdown, so we can use an "admonition" to have this warning text render nicer in the web documentation.
You could argue that `!!! warning` is a little weird to see on the CLI. Some alternatives:
- We could opt to not design the CLI help text around markdown and skip the change to the `jj util exec` help in this commit.
- We could adopt some kind of format that can be rendered well in both contexts.
- Could sticking to specific formatting constructs by convention.
- Could use/create an actual translation tool from CLI format to Markdwon.
- We could keep separate versions of web and CLI documentation. (Seems like a bad idea for the foreseeable future, because we don't have the resources to constantly keep both up-to-date and sync.)
I'm in favor of just writing Markdown in the CLI help text for now.
The current implementation is silly, which will be reimplemented to be using
toml_edit::DocumentMut. "jj config set" will probably be ported to this API.
This patch removes pre-merge steps which depend on the ConfigBuilder API.
Some of Vec<ConfigLayer> could be changed to Vec<config::Config> (or
Vec<ConfigTable>) to drop the layer parameter, but I'm not sure which is
better. parse_config_args() will have to construct ConfigLayer (or ConfigTable +
Option<PathBuf>) if we add support for --config-file=PATH argument.
The `NO_COLOR` spec says that user-specified config is supposed to
override the `$NO_COLOR` environment variable, and we do correctly use
the `ColorFormatter` when `ui.color= "always"` is set in the user's
config. However, it turns out that `NO_COLOR=1` still resulted in no
color because `crossterm` also respects the variable, so the color
codes the `ColorFormatter` requested had no effect. Since `crossterm`
doesn't know about our user configs, it cannot decide whether to
respect `$NO_COLOR`, so let's tell `crossterm` to always use the
colors we tell it to use.
Since most callers don't need to handle loading/parsing errors, it's probably
better to add a separate error type for "get" operations. The other uses of
ConfigError will be migrated later.
Since ConfigGetError can preserve the source name/path information, this patch
also removes some ad-hock error handling codes.
The added function is not "get_table(name) -> Result<Table, Error>" because
callers need to know whether the value was missing or shadowed by non-table
value. We just don't have this problem in template/revset-aliases because these
tables are top-level items.
We currently ignore lines prefixed with "JJ: " (including the space)
in commit messages and in the list of sparse paths from `jj sparse
edit`. I think I included the trailing space in the prefix simply
because that's how we render comments line we insert before we ask the
user to edit the file. However, as #5004 says, Git doesn't require a
space after their "#" prefix. Neither does Mercurial after their "HG:"
prefix. So let's follow their lead and not require the trailing
space. Seems useful especially for people who have their editor
configured to strip trailing spaces.
Some Git merge drivers can partially resolve conflicts, leaving some
conflict markers in the output file. In that case, they exit with a code
between 1 and 127 to indicate that there was a conflict remaining in the
file (since Git uses a shell to run the merge drivers, and shells often
use exit codes above 127 for special meanings such as exiting due to a
signal):
https://git-scm.com/docs/gitattributes#_defining_a_custom_merge_driver
We should support this convention as well, since it will allow many Git
merge drivers to be used with Jujutsu, but we don't run our merge tools
through a shell, so there is no reason to treat exit codes 1 through 127
specially. Instead, we let the user specify which exact exit codes
should indicate conflicts. This is also better for cross-platform
support, since Windows may use different exit codes than Linux for
instance.
When I wrote the original lookup function, I didn't notice that the root config
value could be accessed as &config.cache without cloning. That's the only reason
I added split_safe_prefix().
I would like to delete this alias altogether. By moving it to the
config to start with, users can start overriding it themselves, as
`commit` or whatever they prefer.
This backs out commit fd271d39ad54 "cli: make `jj desc` and `jj st` aliases
hidden."
As we discussed in https://github.com/martinvonz/jj/pull/4811, completion of
flags doesn't work for hidden aliases.
While this is a debug option, it doesn't make sense to store an integer value
as a string. We can parse the environment variable instead. The variable is
temporarily parsed into i64 because i64 is the integer type of TOML.
toml_edit::Value doesn't implement any other integer conversion functions.
The goal is to remove dependency on config::Config and replace the underlying
table type to toml_edit::Table. Other StackedConfig::merge() users will be
migrated in the next batch.
This will help migrate away from config::Config. We'll probably need a better
abstraction to preserve error source indication, but let's leave that for now.
.get_table() isn't forwarded to .get::<T>() because ConfigTable won't implement
Deserialize if we migrate to toml_edit.
If there are multiple files in a subdirectory that are candidates for
completion, only complete the common directory prefix to reduce the number of
completion candidates shown at once.
This matches the normal shell completion of file paths.
UserSettings::get_*() will be changed to look up a merged value from
StackedConfig, not from a merged config::Value. This will help migrate away
from the config crate.
Not all tests are ported to ConfigLayer::parse() because it seemed a bit odd
to format!() a TOML document and parse it to build a table of configuration
variables.
This is heavily based on Benjamin Tan's fish completions:
https://gist.github.com/bnjmnt4n/9f47082b8b6e6ed2b2a805a1516090c8
Some differences include:
- The end of a `--from`, `--to` ranges is also considered.
- `jj log` is not completed (yet). It has a different `--revisions` argument
that requires some special handling.
