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.
Introduce a new strategy for notifying other fish processes of universal
variable changes, as a planned replacement for the complex
strategy_named_pipe. The new strategy still uses a named pipe, but instead
of select() on it, it arranges for SIGIO to be delivered when data is
available. If a SIGIO has been seen since the last check, it means the file
needs to be re-read.
Improves on #7328.
I believe this is the correct behavior, simply skip all whitespace before
a word. Try with
./fish -C 'bind \ef forward-bigword; bind \eb backward-bigword; bind \ed kill-bigword; bind \cw backward-kill-bigword'
Also unrelated formatting fixes. I don't think a CI failure on unformatted
code is warranted but I wish it could do that behind the scenes.
So we can do something on every edit, for example repaint the pager (#7318).
This patch fixes pager refiltering and repainting when pressing Control+U
after typing something in the search field.
Implement this by moving the convenience functions from editable_line_t to
the reader, so we have fewer places where we need to refilter. Essentially we
only have two cases: insertions at the cursor are handled by insert_string(),
and all others go through push_edit(). This should also make it clearer
where we update undo_history.may_coalesce.
This commit was on the history-search-edit-needle branch, so it should
work fine. I hope it does play well with some recent changes.
In 6d339df61 (Factor repainting decions from readline commands better
in the reader), insert_string() was simplified a lot, mirror that.
The tests for editable_line_t are not that useful anymore since the caller has
to decide whether to coalesce insertions, but I guess they don't hurt either.
We should have more tests for some interactive scenarios like undo and the
pager filtering.
This used to be used to determine which token contained the cursor, so
as to highlight potential paths. But now we highlight all potential paths,
so we can remove the field.
The topic monitor allows a client to wait for multiple events, e.g. sigchld
or an internal process exit. Prior to this change a client had to specify
the list of generations and the list of topics they are interested in.
Simplify this to just the list of generations, with a max-value generation
meaning the topic is not interesting.
Also remove the use of enum_set and enum_array, it was too complex for what
it offered.
builtins output to stdout and stderr via io_streams_t. Prior to this fix, it
contained an output_stream_t which just wraps a buffer. So all builtin output
went to this buffer (except for eval).
Switch output_stream_t to become a new abstract class which can output to a
buffer, file descriptor, or nowhere. This allows for example `string` to stream
its output as it is produced, instead of buffering it.
When fish receives a "cancellation inducing" signal (SIGINT in particular)
it has to unwind execution - for example while loops or whatever else that
is executing. There are two ways this may come about:
1. The fish process received the signal
2. A child process received the signal
An example of the second case is:
some_command | some_function
Here `some_command` is the tty owner and so will receive control-C, but
then fish has to cancel function execution.
Prior to this change, these were handled uniformly: both would just set a
cancellation signal inside the parser. However in the future we will have
multiple parsers and it may not be obvious which one to set the flag in.
So instead distinguish these cases: if a process receives SIGINT we mark
the signal in its job group, and if fish receives it we set a global
variable.
This error only happens on recent versions of gcc, see previous
commit e6bb7fc973 for more info.
Instead of using `ignore_result()` here, I've added a `system_assert`
function/macro that mimics the behavior of all the other `system()`
calls in the file.
This reworks the "a=" detection to be simpler.
If we detect a variable assignment that produces an error,
simply consume it.
We also take the opportunity to not highlight it as an error,
and add some tests.
Original commit is 1ca05d32d3.
This switches parse_util_compute_indents from parsing with parse_tree to
the new ast.
It also reworks the parse_util_compute_indents tests, because
parse_util_compute_indents will be the backing for fish_indent.
fish's handling of terminal sizes is currently rather twisted. The
essential problem is that the terminal size may change at any point from a
SIGWINCH, and common_get_{width,height} may modify it and post variable
change events from arbitrary locations.
Tighten up the semantics. Assign responsibility for managing the tty size
to a new class, `termsize_container_t`. Rationalize locking and reentrancy.
Explicitly nail down the relationship between $COLUMNS/$LINES and the tty
size. The new semantics are: whatever changed most recently takes
precendence.
