The `--entire` would enable output even though the `--quiet` should
have silenced it. These two don't make any sense together so print an
error, because the user could have just left off the `-q`.
We used to just check for the presence of "--" on the command line to
make judgements about which completions to suggest. Now, even if "--" is
present, we can still make different suggestions by taking the cursor's
position into account.
If "--" is present in the command line, it's usually safe to assume that
the user is going to want to complete a file tracked by git so let's
only suggest branches if "--" isn't present.
When there is already a "src:", we assume that it is a valid ref and
just complete "dst". This allows completion of dest if src is e.g. a
commit SHA (completing all possible refs would probably impact
performance).
See issue #3035.
This spewed errors because the `math` invocation got no second
operand:
Testing file checks/sigint.fish ... math: Error: Too few arguments
'1571487730 -'
but only if the `date` didn't do milliseconds, which is the case on
FreeBSD and NetBSD.
(also force the variable to be global - we don't want to have a
universal causing trouble here)
sys/sysctl.h is deprecated on glibc, so it leads to warnings.
According to fa4ec55c96, it was included for KERN_PROCARGS2 for
process expansion, but process expansion is gone, so it's unused now.
(there is another use of it in common.cpp, but that's only on FreeBSD)
Also 1f06e5f0b9 only included
tokenizer.h (present since the initial commit) if KERN_PROCARGS2
wasn't available, so it can't have been important.
This builds and passes the tests on:
- Archlinux, with glibc 2.30
- Alpine, with musl
- FreeBSD
- NetBSD
Universal exported variables (created by `set -xU`) used to show up
both as universal and global variable in child instances of fish.
As a result, when changing an exported universal variable, the
new value would only be visible after a new login (or deleting the
variable from global scope in each fish instance).
Additionally, something like `set -xU EDITOR vim -g` would be imported
into the global scope as a single word resulting in failures to
execute $EDITOR in fish.
We cannot simply give precedence to universal variables, because
another process might have exported the same variable. Instead, we
only skip importing a variable when it is equivalent to an exported
universal variable with the same name. We compare their values after
joining with spaces, hence skipping those imports does not change the
environment fish passes to its children. Only the representation in
fish is changed from `"vim -g"` to `vim -g`.
Closes#5258.
This eliminates the issue #5348 for universal variables.
Consider a group of short options, like -xzPARAM, where x and z are options and z takes an argument.
This commit enables completion of the argument to the last option (z), both within the same
token (-xzP) or in the next one (-xz P).
complete -C'-xz' will complete only parameters to z.
complete -C'-xz ' will complete only parameters to z if z requires a parameter
otherwise, it will also complete non-option parameters
To do so this implements a heuristic to differentiate such strings from single long options. To
detect whether our token contains some short options, we only require the first character after the
dash (here x) to be an option. Previously, all characters had to be short options. The last option
in our example is z. Everything after the last option is assumed to be a parameter to the last
option.
Assume there is also a single long option -x-foo, then complete -C'-x' will suggest both -x-foo and
-xy. However, when the single option x requires an argument, this will not suggest -x-foo.
However, I assume this will almost never happen in practise since completions very rarely mix
short and single long options.
Fixes#332
In e167714899 we allowed recursive calls
to complete. However, some completions use infinite recursion in their
completions and rely on `complete` to silently stop as soon as it is
called recursively twice without parameter (thus completing the
current commandline). For example:
complete -c su -s -xa "(complete -C(commandline -ct))"
su -c <TAB>
Infinite recursion happens because (commandline -ct) is an empty list,
which would print an error message. This commmit explicitly detects
such recursive calls where `complete` has no parameter and silently
terminates. This enables above completion (like before raising the
recursion limit) while still allowing legitimate cases with limited
recursion.
Closes#6171
