This set the term modes to the shell-modes, including disabling
ICRNL (translating \cm to \cj) and echo.
The rationale given was that `reader_interactive_init()` would only be
called >= 250ms later, which I _highly_ doubt considering fish's total
startup time is 8ms for me.
The main idea was that this would stop programs like tmuxinator that
send shortcuts early from failing _iff_ the shortcut was \cj, which
also seems quite unusual.
This works both with `rm -i` and `read` in config.fish, because `read`
explicitly calls `reader_push`, which then initializes the shell modes.
The real fix would involve reordering our init so we set up the
modesetting first, but that's quite involved and the remaining issue
should barely happen, while it's fairly common to have issues with a
prompt in config.fish, and the workaround for the former is simpler, so let's leave it for now.
Partially reverts #2578.
Fixes#2980.
Putting larger members before smaller ones will reduce structure
sizes. bools are 1 byte. on 64bit systems I think they reduced:
wgetopt.h:46: 64 to 56 bytes
builtin_history.cpp:30: 48 to 32 bytes
builtin_status.cpp:91: 32 to 24 bytes
tinyexpr.cpp:69: 40 to 32 bytes
The data stored in these containers is small enough that it is worth
creating distinct sets for each lookup.
In a microbenchmark of these changes, the single-lookup version of the
function with lookups gated on the length of input (bypassed entirely if
the input is longer than the longest key in the container) provided a
1.5x-3.5x speedup over the previous implementation.
Additionally, as the collections are static and their contents are never
modified after startup, it makes no sense to continously calculate the
location of and allocate an iterator for the `!= foo.end()` comparison;
the end iterator is now statically cached.
I'm not expecting massive speed gains out of this change, but the parser
does perform enough of these to make it worth optimizing in this way.
This reverts commit 7a74198aa3.
Believe it or not this commit actually increased copying. When accepting
a value you know you're going to take ownership of, just accept it by
value; then temporaries can invoke the move ctor and blah blah blah.
We really need a lightweight refcounted pass-by-value string to make this
less error prone.
If we switch the bind mode, we add a "force-repaint" there just to
redraw the mode indicator.
That's quite wasteful and annoying, considering that sometimes the prompt can take
half a second.
So we add a "repaint-mode" function that just reexecutes the
mode-prompt and uses the cached values for the others.
Fixes#5783.
As it turns out it didn't work much better, and it fell behind in
support when it comes to things that wcwidth traditionally can't
express like variation selectors and hangul combining characters, but
also simply $fish_*_width.
I've had to tell a few people now to rebuild with widecharwidth after
sending them on a fool's errand to set X variable.
So keeping this option is doing our users a disservice.
* Add "expand-abbr" bind function
This can be used to explictly allow expanding abbreviations.
* Make expanding abbr explicit
NOTE: This accepts them for space only, we currently also do it for \n
and \r.
* Remove now dead code
We no longer trigger an abbr implicitly, so we can remove the code
that does it.
* Fix comment

Directly access the job list without the intermediate job_iterator_t,
and remove functions that are ripe for abuse by modifying a local
enumeration of the same list instead of operating on the iterators
directly (e.g. proc.cpp iterates jobs, and mid-iteration calls
parser::job_remove(j) with the job (and not the iterator to the job),
causing an invisible invalidation of the pre-existing local iterators.
This printed weird things like
```fish
$ functions -x
functions: Unknown option '-x'
(Type 'help functions' for related documentation)
```
Instead, let's make it
```fish
$ functions -x
functions: Unknown option '-x'
(Type 'help functions' for related documentation)
```
This was printed basically everywhere.
The user knows what they executed on standard input.
A good example:
```fish
set c (subme 513)
```
used to print
```
fish: Too much data emitted by command substitution so it was discarded
set -l x (string repeat -n $argv x)
^
in function 'subme'
called on standard input
with parameter list '513'
in command substitution
called on standard input
```
and now it is
```
fish: Too much data emitted by command substitution so it was discarded
set -l x (string repeat -n $argv x)
^
in function 'subme' with arguments '513'
in command substitution
```
See #5434.
Now:
```
cd: Unknown option '-r'
~/dev/fish-shell/share/functions/cd.fish (line 40):
builtin cd $argv
^
in function 'cd' with arguments '-r'
in function 'f'
in function 'd'
in function 'b' with arguments '-1q --wurst'
in function 'a'
called on standard input
```
See #5434.
This printed things like
```
in function 'f'
called on standard input
in function 'd'
called on standard input
in function 'b'
called on standard input
in function 'a'
called on standard input
```
As a first step, it removes the empty lines so it's now
```
in function 'f'
called on standard input
in function 'd'
called on standard input
in function 'b'
called on standard input
in function 'a'
called on standard input
```
See #5434.
This switches env_var_t to be an immutable value type, and stores its
contents via a shared_ptr. This eliminates string copying when fetching
env_var_t values.
If a function process is deferred, allow it to be unbuffered.
This permits certain simple cases where functions are piped to external
commands to execute without buffering.
This is a somewhat-hacky stopgap measure that can't really be extended
to more general concurrent processes. However it is overall an improvement
in user experience that might help flush out some bugs too.
In a job, a deferred process is the last fish internal process which pipes
to an external command. Execute the deferred process last; this will allow
for streaming its output.
