This makes it so instead of marking the error location with a simple
`^`, we mark it with a caret, then a run of `~`, and then an ending `^`.
This makes it easier to see where exactly an error occured, e.g. which
command substitution was meant.
Note: Because this uses error locations that haven't been exposed like
that, it's likely to shake out weirdnesses and inaccuracies. For that
reason I've not adjusted the tests yet.
This stops us from loading the completions for e.g. `./foo` if there
is no `foo` in path.
This is because the completion scripts will call an unqualified `foo`,
and then error out.
This of course means if the script would work because it never calls
the command, we still don't load it.
Pathed completions via `complete --path` should be unaffected because
they aren't autoloaded anyway.

These should be friendlier, but aren't as pedantically accurate.
I think the term "index" is terrible and much prefer "staging area".
Also "rev-parse" simply must be believed to be seen, it can't be
described in a single paragraph. (did you know you can use `git
rev-parse --parseopt` as a replacement for `getopt` in arbitrary
shell scripts?)
This was misguidedly "fixed" in
9e08609f85, which made printf error out
with any "-"-prefixed words as the first argument.
Note: This means currently `printf --help` doesn't print the help.
This also matches `echo`, and we currently don't have anything to make
a literal `--help` execute a builtin help except for keywords. Oh well.
Fixes#9132
"socket.has_ipv6" is basically useless - it tells you python has
been *compiled* with ipv6 support.
Instead just try ipv6 and if that fails with EAFNOSUPPORT (checking
the actual errno), try v4.
Yes, I explicitly do not care to test this on python2.
Fixes#3857
I have an alias called "lg" for
log --color --graph --pretty=format:\'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset\' --abbrev-commit --first-parent
Having that in my completions ensures that git commands essentially
always use one column at most. That's not great, so we now shorten it
to 35 chars (plus an annoying 2 for ".." because I can't be bothered
to check for unicode support - an argument for a "string ellipsize", I guess?)
* Disclose pager to screen height immediately
This removes that bit where we only show 4 rows at most at first,
instead we disclose between half of terminal height up to the full terminal height (but still at least 4 rows).
This results in less pressing of tab to get the other results, and
better visibility of results.
Unlike moving it to the actual top of the screen, it's not as jarring and doesn't push terminal history off-screen as much.
Fixes#2698
This used to be kept, so e.g. testing it with
fish_read_limit=5 echo (string repeat -n 10 a)
would cause the prompt and such to error as well.
Also there was no good way to get back to the default value
afterwards.
* string repeat: Don't allocate repeated string all at once
This used to allocate one string and fill it with the necessary
repetitions, which could be a very very large string.
Now, it instead uses one buffer and fills it to a chunk size,
and then writes that.
This fixes:
1. We no longer crash with too large max/count values. Before they
caused a bad_alloc because we tried to fill all RAM.
2. We no longer fill all RAM if given a big-but-not-too-big value. You
could've caused fish to eat *most* of your RAM here.
3. It can start writing almost immediately, instead of waiting
potentially minutes to start.
Performance is about the same to slightly faster overall.
This newline apparently dates back to when we required all statements to
be terminated; but our AST no longer requires that so we can remove
this. No functional change expected here.
GIT_WORK_TREE is an environment variable which tells git where the
worktree is. It may be set by the user or by git itself, e.g. when
running `git rebase -i --exec ...`. If it is set, it overrides the
working directory, causing the `git checkout` from FetchContent_Populate
to fail. Clear this variable.
Do the same for GIT_DIR for the same reason.
A way to reproduce the failure that this commit fixes is:
git rebase -i HEAD^^^ --exec 'ninja -C /path/to/build/dir fish'
prior to this commit, using the fetched PCRE2, this would fail in CMake.
The previous fix was reverted because it broke another scenario. Add tests
for both scenarios.
The first test exposes another problem: autosuggestions are sometimes not
recomputed after selecting the first completion with Tab Tab. Fix that too.
"git add ./" shows only hidden files (if at all). It should show all files
that can be added.
The problem is that candidates come from "git status" which prints clean
relative paths. Let's allow some unclean paths.
This is far from a complete fix but it should work for the common scenario.
Observe that wildcard_complete_internal() actually filters out all non-hidden
files, if the query is `./`.
Closes#9091
This makes it easy to see where the individual commands start. Perhaps we
can get rid of this once we have syntax highlighting for the commands in
the history pager, or if we add timestamps as descriptions.
Note that every change to the search field still starts a new search, from
the end of history. We could change this in future but it's unclear to me
what the expected behavior is. I don't find the traditional readline behavior
very intuitive.
This reimplements ridiculousfish/control_r which is a more future-proof
approach than #6686.
Pressing Control+R shows history in our pager and allows to search filter
commands with the pager search field.
On the surface, this works just like in other shells; though there are
some differences.
- Our pager shows multiple results at a time.
- Other shells allow to use up arrow/down arrow to select adjacent entries
in history. Shouldn't be hard to implement but the hidden state might
confuse users and it doesn't play well with up-or-search, so this is
left out.
Users might expect the history pager to use subsequence matching (fuzzy
matching) like the completion pager, however due to the history pager design it
uses substring matching. We could change this in future, however that means
we would also want to change the ordering from "reverse-chronological" to
"longest common subsequence" (e.g. what fuzzy finders do), because otherwise
a query "fis" might give this ordering:
fsck /dev/disk/by-partlabel/Linux\x20filesystem
fish
which is probably not what the user wants.
The pager shows only a small number of history items at a time. This is
because, as explained above, the history pager does not support subsequence
matching, so navigating it does not scale well.
Closes#602
