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.
This would still remove non-existent paths, which isn't a strict
inversion and contradicts the docs.
Currently, to only allow paths that exist but don't pass a type check,
you'd have to filter twice:
path filter -Z foo bar | path filter -vfz
If a shortcut for this becomes necessary we can add it later.
This is now added to the two commands that definitely deal with
relative paths.
It doesn't work for e.g. `path basename`, because after removing the
dirname prepending a "./" doesn't refer to the same file, and the
basename is also expected to not contain any slashes.
Because we now count the extension including the ".", we print an
empty entry.
This makes e.g.
```fish
set -l base (path change-extension '' $somefile)
set -l ext (path extension $somefile)
echo $base$ext
```
reconstruct the filename, and makes it easier to deal with files with
no extension.
This means "../" components are cancelled out even after non-existent
paths or files.
(the alternative is to error out, but being able to say `path resolve
/path/to/file/../../` over `path resolve (path dirname
/path/to/file)/../../` seems worth it?)
This sorts paths by basename, dirname or full path - in future
possibly size or age.
It takes --invert to invert the sort and "--what=basename|dirname|..."
to specify what to sort
This can be used to implement better conf.d sorting, with something
like
```fish
set -l sourcelist
for file in (path sort --what=basename $__fish_config_dir/conf.d/*.fish $__fish_sysconf_dir/conf.d/*.fish $vendor_confdirs/*.fish)
```
which will iterate over the files by their basename. Then we keep a
list of their basenames to skip over anything that was already
sourced, like before.
The recent change to skip the newline for `string` changed this, and
it also hit builtin path (which is in development separately, so it's
not like it broke master).
Let's pick a good default here.
Yeah, the macOS tests fail because it's started in /private/var... with a
$PWD of /var.... So resolve canonicalizes the path, which makes it no
longer match $PWD.
Simply use pwd -P
This just goes back until it finds an existent path, resolves that,
and adds the normalized rest on top.
So if you try
/bin/foo/bar////../baz
and /bin exists as a symlink to /usr/bin, it would resolve that, and
normalize the rest, giving
/usr/bin/foo/baz
(note: We might want to add this to realpath as well?)
