If the completion pager renders as
foo1 bar1 baz1 qux1
foo2 bar2 baz2
foo3 bar3 baz3
and we go backwards from "foo1" (using left arrow), we'll end up at "baz3",
not "qux1". Pretty smart!
If however we go backwards once more, nothing happens.
The root cause is that there are two different kinds of selection indices:
the one before rendering (9/qux1) and the one after we cleverly subtract
the half-filled last column (8/baz3). The backwards movement ends up
decrementing the first, so it moves from 9 to 8 and nothing changes in
the rendering.
Fix this by using the selection index that we actually rendered.
There is another caller that relies on the old behavior of using the unrendered
selection index. Make it use a dedicated overload that does not depend on
the rendering.
Otherwise realpath would add the cwd, which would be broken if fish
ever cd'd.
We could add the original cwd, but even that isn't enough, because we
need *the parent's* idea of cwd and $PATH.
Or, alternatively, what we need is for the OS to give us the actual
path to ourselves.
get_executable_path says: "This needs to be realpath'd"
So how about we do that? The only other place we use it is fish.cpp,
and we realpath it there already.
See #9085
Our pager computes the selected completion based on its rendering. The number
of rows affect the selection, in particular when moving left from the top
left cell. This computation breaks if the number of rows is zero, which
happens in at least
two scenarios:
1. If the completion pager was not shown (as is the case for complete-or-search)
2. If the search field had filtered away every candidate but not anymore.
I believe in these scenarios the selected completion index is always 0,
so let's fix the selection for that case.
Probably too minor for a changelog entry.
Closes#9080
Posix allows this as an alternative with the same semantics for read.
Found in conjunction with #9067.
Should be no functional difference on other systems.
The wait status value, which we also use internally, is read by a
bunch of macros.
Unfortunately because we want to *create* such a value, and some
systems lack the "W_EXITCODE" macro to do that, we need to figure out
how it's encoded.
So we simply check a specific value, and assume the encoding from
that.
On Haiku the return status is in the lower byte, on other systems it's
typically the upper byte.
TODO: Test on musl (that's the other system without W_EXITCODE).
Fixes#9067
PR #6777 changed all the keys to uppercase, but many Vi commands are case
sensitive.
PR #7908 changed the "u" binding but the documentation still had the old
meaning.
These are used in prompts only, and it feels weird not to have them.
In practice, fish_color_host_remote would not be used at all (just
because you switched from the default theme!), while fish_color_status
would fall back on a different value.
That'll be adjusted in the next commit.
This was an inadvertent change from
cc632d6ae9.
Because we used wgetcwd directly before, we always got the "physical"
resolved $PWD.
There's an argument to be made to use the logical $PWD here as well
but I prefer not to make changes lik that in a random commit without
good reason.
This can be used to print the modification time, like `stat` with some
options.
The reason is that `stat` has caused us a number of portability
headaches:
1. It's not available everywhere by default
2. The versions are quite different
For instance, with GNU stat it's `stat -c '%Y'`, with macOS it's `stat
-f %m`.
So now checking a cache file can be done just with builtins.
/etc/hosts specifies, that everything after a #-character is to be
treated as a comment. The current __fish_print_hostnames however only
considers #-characters at the beginning of a line.
Thus the comment from following valid hosts-entry would end up in the
completion output:
1.2.3.4 myhost # examplecomment
getent hosts properly handles comments.
These are non-POSIX extensions other test(1) utilities implement,
which compares the modification time of two files as proposed for
fish in #3589: testing if one file is newer than another file.
-ef is a common extension to test(1) which checks if two paths refer
to the same file, by comparing the dev and inode numbers.
As explained by the comment, this was dead code. If it were ever executed,
it would cause very weird behavior because it would make some completions
randomly affect others.
Let's just print a warning (maybe this is better than crashing?).
