When building the document with Sphinx, the following warning is displayed, so add end-string.
"../CHANGELOG.rst:29: WARNING: Inline literal start-string without end-string."
This fixes the following problem: if a command is entered while the
previous command is still executing, fish will see it all at once and
execute it before syntax highlighting as a chance to start. So the
command will appear wrong on the terminal. Fix this by detecting this
case and performing a fast no-io highlight.
An example of how to reproduce this:
run `sleep 3` and then type `echo foo` while the sleep is still running.
This cleans up some exit code processing. Previously a failed exec
would produce exit code 125 unconditionally, while a failed posix_spawn
would produce exit code 1 (!).
With this change, fish reports exit code 126 for not-executable, and 127
for file-not-found. This matches bash.
When regenerating documentation with Sphinx, there's a warning issued about CHANGELOG.rst:
```
../CHANGELOG.rst:33: WARNING: Document or section may not begin with a transition.
```
This is almost identical to the fix in commit 84a89f5195.
Consider
$ complete -c foo -a 'aab aaB' -f
$ foo A<TAB>
since 28d67c8 we would insert the common prefix AND show the pager.
Due to case-insensitive comparison, "b/B" was considered to be part
of the prefix. Since the prefix is added to each pager item [1]
we get wrong results. Fix this by removing the insensitive comparison
between completions - I don't think it was of much use anyway.
Commandline tokens are still matched case-insensitively, this is
just about completions.
Test this by running interactive fish inside tmux (pexpect's terminal
emulation not have enough capabilities). Also add tests for recent
interactive regressions #7526 and #7738.
Closes#3978
[1]: b38a23a would solve this differently by giving every pager item
its own prefix, but was reverted since it needs more fixes.
* Rewrite the real file if history file is a symlink
When the history file is a symbolic link, `fish` used to overwrite
the link with a real file whenever it saved history. This makes
it follow the symlink and overwrite the real file instead.
The same issue was fixed for the `fish_variables` file in 622f2868e
from https://github.com/fish-shell/fish-shell/pull/7728.
This makes `fish_history` behave in the same way. The implementation
is nearly identical.
Since the tests for the two issues are so similar, I combined them
together and slightly expanded the older test.
This also addresses https://github.com/fish-shell/fish-shell/issues/7553.
* Add user-facing error when history renaming fails
Currently, when history file renaming fails, no message is shown to the
user. This happens, for instance, if the history file is a symlink
pointing to another filesystem.
This copies code (with a bit of variation, after reviewer comments) from
589eb34571/src/env_universal_common.cpp (L486-L491)
into `history.cpp`, so that a message is shown to the user.
* fixup! Rewrite the real file if history file is a symlink
When `fish` is running in the Chrome OS Linux VM (Crostini),
both `help` and `fish_config` opened a "file not found"
page. That is because on Crostini, `BROWSER` is usually set to
`garcon-url-handler`, which opens URLs in the host OS Chrome
browser. That browser lacks access to the Linux file system.
This commit fixes these commands. `help` now opens the URL on
www.fishshell.com. `fish_config` now opens the URL for the
server it starts. Previously, it opened a local file that
redirects to the same URL.
In the case of `help`, the situation could be improved further
by starting a web server to serve help. I don't know of another
way to access `/share/fish` from outside the VM without user
intervention, and I think that might be a part of the security
model for the Crostini VM.
It's hard to write a test for this. I checked that `help math`,
`python2 webconfig.py`, and `python3 webconfig.py` work on my
machine running in Crostini.
In this context, as it stands, $last_pid will give fish's pid (because
of pgroup shenanigans).
Since that doesn't really work, just `disown` without and let fish
figure out what the last process was.
Theoretically this has an issue if someone started a background
process *before* the python script *and* that exits before we run
disown.
That's a vanishingly small window and this is only run on first start,
so it seems acceptable.
Fixes#7739.
Apparently the fix for #6269 doesn't work until we set job-control to
full, which we won't do for this release.
So just drop it from the CHANGELOG.
See #7739.
The user may write for example:
echo foo >&5
and fish would try to output to file descriptor 5, within the fish process
itself. This has unpredictable effects and isn't useful. Make this an
error.
Note that the reverse is "allowed" but ignored:
echo foo 5>&1
this conceptually dup2s stdout to fd 5, but since no builtin writes to fd
5 we ignore it.
Similar to what fish_indent does. After typing "echo \" and hitting return,
the cursor will be indented.
A possible annoyance is that when you have multiple indented lines
echo 1 \
2 \
3 \
4 \
If you remove lines in the middle with Control-k, the lines below
the deleted one will start jumping around, as they are disconnected
from and reconnected to "echo".
If a variable is undefined, but it looks like it will be defined by the
current command line, assume the user knows what they are doing.
This should cover most real-world occurrences.
Closes#6654
When pasting a multiline command with indented blocks, extra indentation
from spaces, or tabs, is generally undesirable, because fish already indents
pipes and blocks. Discard the indentation unless the cursor or the pasted
part is inside quotes.
Users who copied fish_clipboard_paste need to update it because
__fish_commandline_is_singlequoted had an API change and was renamed.
After commit 6dd6a57c60, 3 remaining
builtins were affected by uint8_t overflow: `exit`, `return`, and
`functions --query`.
This commit:
- Moves the overflow check from `builtin_set_query` to `builtin_run`.
- Removes a conflicting int -> uint8_t conversion in `builtin_return`.
- Adds tests for the 3 remaining affected builtins.
- Simplifies the wording for the documentation for `set --query`.
- Does not change documentation for `functions --query`, because it does
not state the exit code in its API.
- Updates the CHANGELOG to reflect the change to all builtins.
