This makes it so
1. The informative status can work without showing untracked
files (previously it was disabled if bash.showUntrackedFiles was
false)
2. If untrackedfiles isn't explicitly enabled, we use -uno, so git
doesn't have to scan all the files.
In a large repository (like the FreeBSD ports repo), this can improve
performance by a factor of 5 or up.
In b0084c3fc4, we refactored out event handlers get removed. But this
also caused us to remove "one-shot" handlers even if they have not yet
been fired. Fix this.
This concerns running a key binding which invokes a command. If that
command modifies the tty, then fish will spot the modification later and
then react to it by redrawing the prompt. However tty modifications may
be benign or desirable; for example switching the cursor from a line to
a block. Fix this by re-fstating the tty after running external
commands.
Fixes#3481
Previously, `kill-whole-line` kills the line and its following
newline. This is insufficient when we are on the last line, because
it would not actually clear the line. The cursor would stay on the
line, which is not the correct behavior for bindings like `dd`.
Also, `cc` in vi-mode used `kill-whole-line`, which is not correct
because it should not remove any newlines. We have to introduce
another special input function (`kill-inner-line`) to fix this.
Arguments to --ignored were introduced in Git 2.16, from January 2018.
The git completions specifically work around this, allowing older
versions to be used; match this in the git prompt.
Fixes the tests on CentOS 7.
This is broken in narrow screens - the sidebar shrinks to unusable
proportions but still stays.
So instead we go the *other* way, force the left margin and undo the flexifying.
(again we should really stop relying on sphinx' css)
When the user adds a completion for a command, we push it to the front
of the completion list so it appears first; for that reason we don't
want to use a vector. However we can do better than std::list; try using
std::forward_list which is singly linked. No functional change here (but
we will see if this breaks any old platforms in which case it's fine to
revert this).
Prior to this change, the list of completions was stored as a
std::unordered_set, using some funny comparators and suspicious
const_cast to make it map-like. Use a real map instead, simplifying
the code. No functional change here.
Sphinx 5.0 makes the document div a flex container, which clashes
badly with the margin that earlier versions need.
So we remove the margin and flex the div ourselves, which should work
with either.
It's time we make this freestanding - these changes are annoying.
When switching this to use `git status`, I neglected to use the
correct definition of what a "dirty" and a "staged" change is.
So this now showed already staged files still as "dirty".
Fixes#8986
Prior to this commit, setting a universal variable may trigger syncing
against the file which will modify other universal variables. But if we
want to support multiple environments we need the parser to decide when to
sync uvars. Shift the decision of when to sync to the parser itself. When a
universal variable is modified, now we just set a flag and it's up to the
(main) parser when to pick it up. This is hopefully just a refactoring with
no user-visible changes.
This makes it so `complete -c foo -n test1 -n test2` registers *both*
conditions, and when it comes time to check the candidate, tries both,
in that order. If any fails it stops, if all succeed the completion is offered.
The reason for this is that it helps with caching - we have a
condition cache, but conditions like
```fish
test (count (commandline -opc)) -ge 2; and contains -- (commandline -opc)[2] length
test (count (commandline -opc)) -ge 2; and contains -- (commandline -opc)[2] sub
```
defeats it pretty easily, because the cache only looks at the entire
script as a string - it can't tell that the first `test` is the same
in both.
So this means we separate it into
```fish
complete -f -c string -n "test (count (commandline -opc)) -ge 2; and contains -- (commandline -opc)[2] length" -s V -l visible -d "Use the visible width, excluding escape sequences"
+complete -f -c string -n "test (count (commandline -opc)) -ge 2" -n "contains -- (commandline -opc)[2] length" -s V -l visible -d "Use the visible width, excluding escape sequences"
```
which allows the `test` to be cached.
In tests, this improves performance for the string completions by 30%
by reducing all the redundant `test` calls.
The `git` completions can also greatly benefit from this.
This adds a path builtin to deal with paths.
It offers the following subcommands:
filter to go through a list of paths and only print the ones that pass some filter - exist, are a directory, have read permission, ...
is as a shortcut for filter -q to only return true if one of the paths passed the filter
basename, dirname and extension to print certain parts of the path
change-extension to change the extension to a different one (as a string operation)
normalize and resolve to canonicalize the paths in various flavors
sort to sort paths, also only using the basename or dirname as a key
The definition of "extension" here was carefully considered and should line up with how extensions are actually used - ~/.bashrc doesn't have an extension, but ~/.conf.d does (".d").
These subcommands all compose well - they can read from arguments or stdin (like string), they can use null-delimited input or output (input is autodetected - if a NULL happens in the first PATH_MAX bytes it switches automatically).
It is both a failglob exception (so like set if a glob passed to it fails it just doesn't get any arguments for it instead of triggering an error), and passes output to command substitution buffers explicitly split (like string split0) so newlines are easy to handle.
