This makes it so
```fish
if -e foo
# do something
end
```
complains about `-e` not being a command instead of `end` being used
outside of an if-block.
That means both that `-e` could now be used as a command name (it
already can outside of `if`!) *and* that we get a better error!
The only way to get `if` to be a decorated statement now is to use `if
-h` or `if --help` specifically (with a literal option).
The same goes for switch, while and begin.
It would be possible, alternatively, to disallow `if -e` and point
towards using `test` instead, but the "unknown command" message should
already point towards using `test` more than pointing at the
"end" (that might be quite far away).
- This is untested and unused, string ownership is very much subject to change
- Ports the minimally necessary parts of complete.rs as well
- This should fix an infinite loop in `create_directory` in `path.rs`, the first
`wstat` loop only breaks if it fails with an error that's different from
EAGAIN
- wildcard_match is now closer to the original that is linked in a comment, as
pointer-arithmetic translates very poorly. The act of calling wildcard
patterns wc or wildcard is kinda confusing when wc elsewhere is widechar.
This is in regards to a comment on 290d07a833, which resulted in 46c967903d.
Those commits handled the default path when it is unset on startup.
DEFAULT_PATH is used when PATH is unset at runtime as far as I can tell.
As far as I can tell this has had the non-overidding ordering behavior since inception
(or at least 17 years ago ea998b03f2).
We don't change anything about compilation-setup, we just immediately jump to
Rust, making the eventual final swap to a Rust entrypoint very easy.
There are some string-usage and format-string differences that are generally
quite messy.
In CMake this used a `version` file in the CARGO_MANIFEST_DIR, but
relying on that is problematic due to change-detection, as if we add
`cargo-rerun-if-changed:version`, cargo would rerun every time if the file does
not exist, since cargo would expect the file to be generated by the
build-script. We could generate it, but that relies on the output of `git
describe`, whose dependencies we can only limit to anything in the
`.git`-folder, again causing unnecessary build-script runs.
Instead, this reads the `FISH_BUILD_VERSION`-env-variable at compile time
instead of the `version`-file, and falls back to calling git-describe through
the `git_version`-proc-macro. We thus do not need to deal with extraneous
build-script running.
C++ main used getopt (no w!), which appears to internally print
error-messages. The Rust version will use `wgetopter_t`, and therefore needs to
print this itself.
- It is currently never set, but will be set once `main` is ported
- `should_suppress_stderr_for_tests` used to be PROGRAM_NAME !=
TESTS_PROGRAM_NAME, but the equivalent C++ code was
`!std::wcscmp(program_name, TESTS_PROGRAM_NAME)`, and `wcsmp` returns
zero if they are equal, thus is equivalent to `==` in Rust
Similar to `time`, except that one is more common as a command.
Note that this will also allow `builtin and`, which is somewhat
useless, but then it is also useless outside of a pipeline.
Addition to #9985
This allows e.g. `foo | command time`, while still rejecting `foo | time`.
(this should really be done in the ast itself, but tbh most of
parse_util kinda should)
Fixes#9985
- "1.6.0" now supports formatting let-else statements which we use liberally,
and appears to have some fixes in regards to long-indented-lines with macros
like `wgettext_ft!`
- This commit updates the formatting so that devs with the latest stable don't
see random format-fixes upon running `cargo fmt`
Note: This *requires* an argument after the format string:
```rust
FLOGF!(debug, "foo");
```
won't compile. I think that's okay, because in that case you should
just use FLOG.
An alternative is to make it skip the sprintf.
"FLOGF!" is supposed to treat its first argument as a format
string (but doesn't because that part isn't implemented currently).
That means running something like
```rust
FLOGF!(term_support, "curses var", var_name, "=", value);
```
That would rightly just print "curses var", ignoring the other
arguments.
By contrast, FLOG! is the literal "just join these as a string"
version.
- Make CMake use the correct target-path
- Make build.rs use the correct target dir
Workspaces place it in the project root by default, the alternative to making
this change is to add a `.cargo/config.toml` file with
```toml
[build]
target-dir = "fish-rust/target"
```
Which I think is unnecessary, as we likely want to use the new location anyways.
- This allows running `cargo fmt/clippy/test/etc` from root
- Ideally the root should be the fish-rust package instead of being virtual, but
that requires changed to CMake/Corrosion. This change should instead be
completely compatible with our existing setup.
- This also means we will only have on `Cargo.lock` for all current and future
crates.
This was "function", needs to be "function*s*".
It was only an issue in the option parsing because we set cmd there
again instead of passing it. Maybe these should just be file-level constants?
