Prior to this change, abbreviations were stored as fish variables, often
universal. However we intend to add additional features to abbreviations
which would be very awkward to shoe-horn into variables.
Re-implement abbreviations using a builtin, managing them internally.
Existing abbreviations stored in universal variables are still imported,
for compatibility. However new abbreviations will need to be added to a
function. A follow-up commit will add it.
Now that abbr is a built-in, remove the abbr function; but leave the
abbr.fish file so that stale files from past installs do not override
the abbr builtin.
Let's hope this doesn't causes build failures for e.g. musl: I just
know it's good on macOS and our Linux CI.
It's been a long time.
One fix this brings, is I discovered we #include assert.h or cassert
in a lot of places. If those ever happen to be in a file that doesn't
include common.h, or we are before common.h gets included, we're
unawaringly working with the system 'assert' macro again, which
may get disabled for debug builds or at least has different
behavior on crash. We undef 'assert' and redefine it in common.h.
Those were all eliminated, except in one catch-22 spot for
maybe.h: it can't include common.h. A fix might be to
make a fish_assert.h that *usually* common.h exports.
If we ever need any of these... they're in this commit:
fish_wcswidth_visible()
status_cmd_opts_t::feature_name
completion_t::is_naturally_less_than()
parser_t::set_empty_var_and_fire()
parser_t::get_block_desc()
parser_keywords_skip_arguments()
parser_keywords_is_block()
job_t::has_internal_proc()
fish_wcswidth_visible()
This makes it so we treat backspaces as width -1, but never go below a
0 total width when talking about *lines*, like in screen or string
length --visible.
Fixes#8277.
Now that we have multiple clients of count_preceding_backslashes, factor
it out from fish_indent into wcstringutil.h, and then use the shared
implementation.
The pager cleanup missed that the existing token could already include active (as in unescaped) expansions, and just escaped them all.
This means things like `ls ~/<TAB>` would escape the `~`, which is obviously wrong and makes it awkward to use.
This reverts commit b38a23a46d.
I fully expect that we'll try again, but there's no use in keeping master broken while that happens.
Fixes#7526.
"smartcase" performs case-insensitive matching if the input string is all
lowercase, and case-sensitive matching otherwise. When completing e.g.
files, we will now show both case sensitive and insensitive completions if
the input string does not contain uppercase characters.
This is a delicate fix in an interactive component with low test coverage.
It's likely something will regress here.
Fixes#3978
This is an attempt to simplfy some completion logic. It mainly refactors
reader_data_t::handle_completions such that all completions have the token
prepended; this attempts to simplify the logic since now all completions
replace the token. It also changes how the pager prefix works. Previously
the pager prefix was an extra string that was prepended to all
completions. In the new model the completions already have the prefix
prepended and the prefix is used only for certain width calculations.
This is a somewhat frightening change in an interactive component with
low test coverage. It tweaks things like how long completions are
ellipsized. Buckle in!
In preparation for introducing "smart case", refactor string fuzzy
matching. Specifically split out the case folding and match type into
separate fields, so that we can introduce more case folding types without
a combinatoric explosion.
This is used to decide which fuzzy match is better, however it is used
only in wildcard expansion and not in actual completion ranking or
anywhere else where it could matter. Try removing the compare() call
and implementation.
What compare() did specially was compare distances, e.g. it ranks
lib as better than libexec when expanding /u/l/b. But the tests did not
exercise this so it's hard to know if it's working. In preparation for a
refactoring, remove it.
This is like wcs2string, but instead of returning a std::string, it invokes
a user-supplied function with each converted character.
The idea is to allow interleaved conversion and output.
This runs build_tools/style.fish, which runs clang-format on C++, fish_indent on fish and (new) black on python.
If anything is wrong with the formatting, we should fix the tools, but automated formatting is worth it.
The official fish documentation makes no mention of how `string split`
treats empty tokens, e.g. splitting 'key1##key2' on '#' or (more
confusingly) splitting '/path' on '/'. With this commit, `string split`
now has an option to exclude zero-length substrings from the resulting
array with a new `--no-empty/-n`. The default behavior of preserving
empty entries is kept so as to avoid breakage.
From the discussion in #3802, handling spaces within braces more
gracefully. Leading and trailing whitespace that isn't quoted or escaped
is stripped, whitespace in the middle is preserved. Any whitespace
encountered within expansion tokens is treated as a single space,
similar to how programming languages that don't hard break tokens/quotes
on line endings would.
For this change I decided to bundle the remaining modules that need to be
resytyled because only two were large enough to warrant doing on their own.
Reduces lint errors from 225 to 162 (-28%). Line count from 3073 to 2465 (-20%).
Another step in resolving issue #2902.
Remove the "make iwyu" build target. Move the functionality into the
recently introduced lint.fish script. Fix a lot, but not all, of the
include-what-you-use errors. Specifically, it fixes all of the IWYU errors
on my OS X server but only removes some of them on my Ubuntu 14.04 server.
Fixes#2957
This change moves source files into a src/ directory,
and puts object files into an obj/ directory. The Makefile
and xcode project are updated accordingly.
Fixes#1866
