This allows giving a range like "5..7".
It works in combination with more (including overlapping) ranges or
single indices.

This test wants to generate a U+FDD2 to see it is not mishandled.
To do so, we tried to use sh, which on my system is bash and can do
`$'\ufdd2'`.
Unfortunately on other systems it might be dash, which won't do that.
Since I don't know of a good no-dependency portable way to generate
this (I dimly remember python3 being a shim on some systems, so I do
not want to invoke it here), we'll just use our own printf.
Which is a worse test, we control both parts, but it'll do.
Fixes#10134
These printed "Unknown error while evaluating command substitution".
Now they print something like
```
fish: for: status: cannot overwrite read-only variable
for status in foo; end
^~~~~^
in command substitution
fish: Invalid arguments
echo (for status in foo; end)
^~~~~~~~~~~~~~~~~~~~~~~^
```
for `echo (for status in foo; end)`
This is, of course, still not *great*. Mostly the `fish: Invalid
arguments` is basically entirely redundant.
An alternative is to simply skip the error message, but that requires some
more scaffolding (describe_with_prefix adds some error messages on its
own, so we can't simply say "don't add the prefix if we don't have a
message")

This was already supposed to handle `--foo=bar<TAB>` cases, except it
printed the `--foo=` again, causing fish to take that as part of the
token.
See #9538 for a similar thing with __fish_complete_directories.
Fixes#10011
(cherry picked from commit b03327f5d2)
This used to print all codepoints outside of the ASCII range (i.e.
above 0x80) in \uXXXX or \UYYYYYYYY notation.
That's quite awkward, considering that this is about keys that are
being pressed, and many keyboards have actual symbols for these on
them - I have an "ö" key, so I would like to use `bind ö` and not
`bind \u00F6`. So we go by iswgraph.
On a slightly different note, `\e` was written as `\c[ (or \e)`. I do
not believe anyone really uses `\c[` (the `[` would need to
be escaped!), and it's confusing and unnecessary to even mention that.
(cherry picked from commit 55c425a0dd)
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
(cherry picked from commit 482616f101)
We could end up overflowing if we print out something that's a multiple of the
chunk size, which would then finish printing in the chunk-printing, but not
break out early.
(cherry picked from commit 6325b3662d)
This makes `fish -c begin` fail with a status of 127 - it already
printed a syntax error so that was weird. (127 was the status for
syntax errors when piping to fish, so we stay consistent with that)
We allow multiple `-c` commands, and this will return the regular
status if the last `-c` succeeded.
This is fundamentally an extremely weird situation but this is the
simple targeted fix - we did nothing, unsuccessfully, so we should
fail.
Things to consider in future:
1. Return something better than 127 - that's the status for "unknown
command"!
2. Fail after a `-c` failed, potentially even checking all of them
before executing the first?
Fixes#9888
(cherry picked from commit a6c36a014c)
Otherwise this would complete
`git --exec-path=foo`, by running `complete -C"'' --exec-path=foo"`,
which would print "--exec-path=foo", and so it would end as
`git --exec-path=--exec-path=foo` because the "replaces token" bit was
lost.
I'm not sure how to solve it cleanly - maybe an additional option to
`complete`?
Anyway, for now this
Fixes#9538.

Another from the "why are we asserting instead of doing something
sensible" department.
The alternative is to make exit() and return() compute their own exit
code, but tbh I don't want any *other* builtin to hit this either?
Fixes#9659
(cherry picked from commit a16abf22d9)
Commit 3b30d92b6 (Commit transient edit when closing pager, 2022-08-31)
inadvertently introduced two regressions to history search:
1. It made Escape keeps the selected history entry,
instead of restoring the commandline before history search.
2. It made history search commands add undo entries.
Fix both of this issues.
Inadvertently broken in a2d816710f,
this made `cd .` no longer offer `cd ../` (same for general file completions
like `ls .`, which only offers dotfiles)
This means cleaning out old universal variables is now just:
```fish
abbr --erase (abbr --list)
```
which makes upgrading much easier.
Note that this erases the currently defined variable and/or any
universal. It doesn't stop at the former because that makes it *easy*
to remove the universals (no running `abbr --erase` twice), and it
doesn't care about globals because, well, they would be gone on
restart anyway.
Fixes#9468.
This now means `abbr --add` has two modes:
```fish
abbr --add name --function foo --regex regex
```
```fish
abbr --add name --regex regex replacement
```
This is because `--function` was seen to be confusing as a boolean flag.
Example output from a Cirrus bionic-asan-clang run:
```
fish: Unknown command: man
/tmp/cirrus-ci-build/share/functions/__fish_man_page.fish (line 30):
if man "$maincmd" &>/dev/null
^~^
in function '__fish_man_page'
�
[I] prompt 9>echo TEXT
[I] prompt 9>echo TEXThrAi
[I] prompt 9>echo TEXThrAi
TEXThrAi
```
Yes, this detected escape, waiting *300ms* and then "h" as being below
the escape timeout of 120ms.
Unfortunately print_hints was true *by default* - so for all builtins
that didn't pass it it would now be false instead.
This resulted in the trailer missing, which includes the line number
and context. So if you ran a script that includes `bind -M` the error
message would now just be "bind: -M: option requires an argument",
with no indication as to where.
This reverts commit 8a50d47a46.
This would print
```
abbr -a -- dotdot --regex ^\\.\\.+\$ --function multicd
```
which expands "dotdot" to "--regex ^\\.\\.+\$...".
Instead, we move the name to right before the replacement, and move
the `--` before that:
```
abbr -a --regex ^\\.\\.+\$ --function -- dotdot multicd
```
It might be possible to improve that, but this at least round-trips.
Historical behavior is to stop option parsing at the first non-option argument.
Since we have added more options, it seemed impractical to keep that behavior.
However people are using options in their abbr expansions ("abbr e emacs
-nw"). To support this, we ignore options. However, we only ignore them
if they are not valid "abbr" options. Let's ignore all options in the
expansion definition, which is a small price to pay to keep most existing
configurations working.
Fixes#9410
This does not fix other cases which used to work, like
abbr x -unknown
Those are hopefully not used by anyone, so I don't think we need to maintain
support for that.
Also default the marker to '%'. So you may write:
abbr -a L --position anywhere --set-cursor "% | less"
or set an explicit marker:
abbr -a L --position anywhere --set-cursor=! "! | less"
This renames abbreviation triggers from `--trigger-on entry` and
`--trigger-on exec` to `--on-space` and `--on-enter`. These names are less
precise, as abbreviations trigger on any character that terminates a word
or any key binding that triggers exec, but they're also more human friendly
and that's a better tradeoff.
set-cursor enables abbreviations to specify the cursor location after
expansion, by passing in a string which is expected to be found in the
expansion. For example you may create an abbreviation like `L!`:
abbr L! --position anywhere --set-cursor ! "! | less"
and the cursor will be positioned where the "!" is after expansion, with
the "| less" appearing to its right.
This adds support for the `--function` option of abbreviations, so that the
expansion of an abbreviation may be generated dynamically via a fish
function.
Prior to this change, abbreviations were stored as fish variables, often
universal. However we intend to add additional features to abbreviations
which would be very awkward to shoe-horn into variables.
Re-implement abbreviations using a builtin, managing them internally.
Existing abbreviations stored in universal variables are still imported,
for compatibility. However new abbreviations will need to be added to a
function. A follow-up commit will add it.
Now that abbr is a built-in, remove the abbr function; but leave the
abbr.fish file so that stale files from past installs do not override
the abbr builtin.
We have had multiple crashes for relative CDPATH entries. Commit 5e274066e
(Always return absolute path in path_get_cdpath, 2019-10-17) tried to fix
all of them but it failed to do justice to its title. Let's fix this to
actually return absolute paths, always. Take care to to normalize the path
because it is used for autosuggestions. The normalization is mostly relevant
for CDPATH=. (the default) but it doesn't hurt others.
Closes#9407
