If we output text and end up in the last column, the sticky right edge
will cause a clr_eos to erase the last character. Ensure this doesn't
happen by not issuing clr_eos in that case.
Fixes#6951
If a readline command is bound to a key sequence which also sends a
signal, then fish will set the cancel flag in addition to handling the
command. But this cancel flag is then persistent. Ensure it gets cleared
after each command.
Fixes#6937
The manual page for statfs(2) only lists SMB_SUPER_MAGIC and
CIFS_MAGIC_NUMBER, but it turns out there's a third type of CIFS/SMB
mount, represented by SMB2_MAGIC_NUMBER.
Haunting me from #6609.
Use inline initializers rather than the constructor, and adopt some
maybe_t.
Also move post_buff_1 and post_buff_2 to local variables instead of
member variables.
Commit 5fccfd83ec, with the fix for #6806,
switched eval to buffer its output (like other builtins do). But this
prevents using eval with commands that wants to see the tty, especially
fzf. So only buffer the output if the output is piped to the next process.
This will solve #6955 (which needs to go into a point release).
builtin_eval needs to know whether to set up bufferfills to capture its
output and/or errput; it should do this specifically if the output and
errput is piped (and not, say, directed to a file). In preparation for
this change, add bools to io_streams_t which track whether stdout and
stderr are specifically piped.
Prior to this fix, builtin_eval would direct output to the io_chain of the
job. The problem is with pipes: `builtin_eval` might happily attempt to
write unlimited output to the write end of a pipe, but the corresponding
reading process has not yet been launched. This results in deadlock.
The fix is to buffer all the output from `builtin_eval`. This is not fun
but the best that can be done until we have real concurrent processes.
Fixes#6806
Give string expansion an (optional) parent pgroup. This is threaded all
the way into eval(). This ensures that in a mixed pipeline like:
cmd | begin ; something (cmd2) ; end
that cmd2 and cmd have the same pgroup.
Add a test to ensure that command substitutions inherit pgroups
properly.

Changes it from

```
(with the trailing empty line - not just a newline)
to
```

* Fire fish_postexec event after tokenization error
This is a fix for issue #6816 "shell integration with tokenization error"
* Pass command-line to fish_postexec on tokenization error
* Rename and move event for tokenization error
For the last 15 years the space was only skipped when the completion
ended in one of "/=@:". Add ".," since they are also sometimes used to
separate independent words within a token.
Fixes#6928
Improves on #6833
Prior to this fix, if job control is enabled but stdin is not a tty, we
would return an error from terminal_maybe_give_to_job which would cause us
to avoid waiting for the job. Instead just return notneeded.
Fixes#6573.
This updates the behavior of tilde to match the behavior found in vim.
In vim, tilde toggles the case of the character under the cursor and
advances one character. In visual mode, the case of each selected
character is toggled, the cursor position moves to the beginning of
the selection, and the mode is changed to normal. In fish, tilde
capitalizes the current letter and advances one word. There is no
current tilde command for visual mode in fish.
This patch adds the readline commands `togglecase-letter` and
`togglecase-selection` to match the behavior of vim more closely. The
only difference is that in visual mode, the cursor is not modified.
Modifying the cursor in visual mode would require either moving it in
`togglecase-selection`, which seems outside its scope or adding
something like a `move-to-selection-start` readline command.
We had previously added a more helpful error message when a literal zero
index was specified when indexing into an array. This patch extends that
coverage to cases indexing into a command substitution, e.g.
```fish
echo (printf "hello\nworld\n")[0]
```
Otherwise it would print "Unknown Signal" on Linux. I didn't see an
obvious way to check signal validity, plus it hardly matters.
Also mimic the output from BSD strsignal on Linux.
For `true`, this makes uses like the
: some description of the job &
we used to have impossible, also it's just *wrong* that true can
return something that isn't true.
For false it's not super important but it should generally be
symmetrical with true.
