Because we reload changed function files, a common issue on upgrading
to 3.4.0 is that fish_title causes errors.
So we simply use the oldschool syntax.
(cherry picked from commit c5a8764db1)
This just defines a constant to whichever tparm implementation we're
using (either the actual, working one the system provides, or our
kludge to paper over Solaris' inadequacies).
This means that there won't be so much ping-ponging of what "tparm"
stands for. "tparm" is the system's function. Only we don't use it,
just like we don't use wcstod directly.
Fixes#8780

* New -n flag for string join command.
This is an argument that excludes empty result items. Fixes#8351
* New documentation for string-join.
The new argument --no-empty was added at string-join manpage.
* New completions for the new -n flag for string join.
* Remove the documentation of the new -n flag of string join0
The reason to remove this new argument in the join0 is that this flag basically doesn't make any difference in the join0.
* Refactor the validation for the string join.
The string join command was using the length of the argument, this commit changes the validation to use the empty function.
* Revert #4b56ab452
The reason for the revert is thath the build broke on the ubuntu in the Github actions.
* Revert #e72e239a1
The reason the compilation on GitHub broke is that the test was weird, it didn't even run it, Common CI systems are typically very very resource-constrained.
* Resolve conflicts in the string-join.rst.
* Resolve conflicts in the "string-join.rst".
commit #1242d0fd7 not fixed all conflicts.
This is supposed to detect color escape sequences, to figure out how
long an escape sequence is, for use in width calculations.
However, the typical color sequences are already taken care of by
is_csi_style_escape_seq because they look like a csi sequence starting
with `\e[` and ending in `m`.
In the entire terminfo database shipped with ncurses 6.3, these are
the terminals that have non-csi color sequences:
at-color
atari-color
atari_st-color
d220-dg
d230-dg
d230c-dg
d430-dg
d430-unix
d430-unix-25
d430-unix-s
d430-unix-sr
d430-unix-w
d430c-dg
d430c-unix
d430c-unix-25
d430c-unix-s
d430c-unix-sr
d430c-unix-w
d470-dg
d470c-dg
dg+fixed
dgmode+color
dgmode+color8
dgunix+fixed
emu
fbterm
i3164
ibm3164
linux-m1b
linux-m2
minitel1
minitel1b
putty-m1b
putty-m2
st52-color
tt52
tw52
tw52-color
xterm-8bit
Most of these were discontinued in the 90s and their manufacturers no
longer exist (like Data General, which went defunct in 1999). The last one is a special mode for xterm that is
fundamentally UTF-8 incompatible because it encodes a CSI as \X9b.
The linux/putty m1b and m2 entries (also for minitel) don't support
color to begin with and the sequences they have in their terminfo
entries are control characters anyway, so the calculation would still
add up.
In turn, what we gain from this is much faster width calculations with
unrecognized escapes -
e.g. `string length -V \efoo` is sped up by a factor of 20.
An alternative would be to skip this if max_colors is > 16 as that is
the most any of these entries can do. The runtime scales linearly with
the number of colors so on those systems it would be reasonably quick anyway.
But given just *how* outdated these are I believe it is okay to just
remove support outright. I do not believe anyone has ever run fish on
any of these.
* Implement fish_wcstod_underscores
* Add fish_wcstod_underscores unit tests
* Switch to using fish_wcstod_underscores in tinyexpr
* Add tests for math builtin underscore separator functionality
* Add documentation for underscore separators for math builtin
* Add a changelog entry for underscore numeric separators
We can't always read in chunks because we often can't bear to
overread:
```fish
echo foo\nbar | begin
read -l foo
read -l bar
end
```
needs to have the first read read `foo` and the second read `bar`. So
here we can only read one byte at a time.
However, when we are directly redirected:
```fish
echo foo | read foo
```
we can, because the data is only for us anyway. The stream will be
closed after, so anything not read just goes away. Nobody else is
there to read.
This dramatically speeds up `read` of long lines through a pipe. How
much depends on the length of the line.
With lines of 5000 characters it's about 15x, with lines of 50
characters about 2x, lines of 5 characters about 1.07x.
See #8542.
Otherwise this does "justify", which in bad cases can spread the text
over the width of the whole line, leaving awkward space between words.
This looks something like
```
The main file is ~/.config/fish/config.fish
```
The current python docs theme also left-aligns.
If a code block includes a line starting with ">", we assume it shows
an interactive session, all lines starting with ">" are commands and
the rest is output.
Unfortunately, in something like:
```
> for val in $PATh
echo "entry: $val"
end
entry: /usr/bin
```
this won't highlight the dangling lines. We could also prefix them
with `>`, but that require us to parse them in blocks or the `end`
would be an error.
So, for now, simply don't give these as a prompt but as a script with
cheesy comments describing the output.
Includes harmonizing the display of options and arguments, standardising
terminology, using the envvar directive more broadly, adding help options to all
commands that support them, simplifying some language, and tidying up multiple
formatting issues.
string documentation is not changed.
This was an oversight in 7fb3880b96, and would have spewed the existing rustup completions if this file was sourced twice (which probably won't happen given autoloading, to be fair).
I have no idea why this kept one component in the one case and none in
the other.
Because we already aggressively shorten the command, we can keep the directory.
This is the simple fix - if we have no valid digit, we have nothing to
return. So instead of returning a NULL, we return an error.
This is already the case for invalid octal escapes (like `\777`).
Fixes#8545
Since the color previews are now wider, we had quite a wide range
where there would only be one. Remove the border around the content
earlier so windows with 1000px width still get two previews in a row.
(making the text shorter would also be an option here)
