Fixes#6798
This re-adds some false positives: functions, builtins and abbreviations
are suggested after commands like sudo but I don't think anyone had
complained about that.
(cherry picked from commit 2a89873e6d686fcff1d26d0914a8b9f90b7cc308)
$XDG_DATA_DIRS/vendor_{completions,conf,functions}.d
Additionally, CMake variables extra_{completions,conf,functions}dir are
appended, if they are not already contained in $XDG_DATA_DIRS.
If XDG_DATA_DIRS is not defined, we fall back to
$__fish_datadir/vendor_completions.d:${extra_completionsdir}
for completions. Same for conf and functions.
This adds initial support for statements with prefixed variable assignments.
Statments like this are supported:
a=1 b=$a echo $b # outputs 1
Just like in other shells, the left-hand side of each assignment must
be a valid variable identifier (no quoting/escaping). Array indexing
(PATH[1]=/bin ls $PATH) is *not* yet supported, but can be added fairly
easily.
The right hand side may be any valid string token, like a command
substitution, or a brace expansion.
Since `a=* foo` is equivalent to `begin set -lx a *; foo; end`,
the assignment, like `set`, uses nullglob behavior, e.g. below command
can safely be used to check if a directory is empty.
x=/nothing/{,.}* test (count $x) -eq 0
Generic file completion is done after the equal sign, so for example
pressing tab after something like `HOME=/` completes files in the
root directory
Subcommand completion works, so something like
`GIT_DIR=repo.git and command git ` correctly calls git completions
(but the git completion does not use the variable as of now).
The variable assignment is highlighted like an argument.
Closes#6048
Presently the completion engine ignores builtins that are part of the
fish syntax. This can be a problem when completing a string that was
based on the output of `commandline -p`. This changes completions to
treat these builtins like any other command.
This also disables generic (filename) completion inside comments and
after strings that do not tokenize.
Additionally, comments are stripped off the output of `commandline -p`.
Fixes#5415Fixes#2705
This adds support for `fish_trace`, a new variable intended to serve the
same purpose as `set -x` as in bash. Setting this variable to anything
non-empty causes execution to be traced. In the future we may give more
specific meaning to the value of the variable.
The user's prompt is not traced unless you run it explicitly. Events are
also not traced because it is noisy; however autoloading is.
Fixes#3427
This reorders many CHANGELOG entries.
The main idea is to keep the "NOTABLE fixes and improvements" for the headline items,
so a bunch of entries (like "Empty uvars can now be exported") are moved to more specific sections.
Other than that, there's some rewording, and the new feature flag is mentioned in Deprecations,
because that's effectively what it is.
