I decided this was just too useful not to include in our final fish 2.x
release. And since it does not modify any existing behavior it is safe
to include at this late date in the process of creating 2.7.
This makes command substitutions impose the same limit on the amount
of data they accept as the `read` builtin. It does not limit output of
external commands or builtins in other contexts.
Fixes#3822
This adds a new capability to the `set` command. It is similar to
running `set` with no other arguments but provides far more detail about
each variable. Such as whether it is set in each of the local, global,
and universal scopes. And the values in each scope. You can also ask for
specific variables to be shown.
Fixes#4265
Rewrite the `abbr` function to store each abbreviation in a separate
variable. This greatly improves the efficiency. For the common case
it is 5x faster. For pathological cases it is upwards of 100x faster.
Most people should be able to unconditionally define abbreviations in
their config.fish without a noticable slow down.
Fixes#4048
This takes a string that is then split upon like `string split`.
Unlike $IFS, the string is used as one piece, not a set of characters.
There is still a fallback to IFS if no delimiter is given, that
behaves exactly as before.
Fixes#4156.
This silences warnings from the compiler about ignoring return value of
‘ssize_t write(int, const void*, size_t)’, declared with attribute
warn_unused_result [-Wunused-result].
The class `completer_t` declares `complete_special_cd`, an unused method. I searched the entire source tree and this declaration seems to be the only instance of `complete_special_cd`. There is no definition or uses which likely means this is dead code.
PR #3691 made most calls to `signal_block()` and `signal_unblock()`
no-ops unless a magic env var is set when fish starts running. It's
been seven months since that change was made and no problems have been
reported. This finishes that work by removing those no-op function calls
and support for the magic env var in our next major release (which won't
happen till at least six months from now).
The primary motivation for --keep-order for `complete` was to support
something like commit history completions, which are returned by git in
reverse chronological order and make no sense alphabetically (they are
SHA1 hashes).
