A Rust data structure that is generic over a type conventionally uses a single
capital letter for the type variable, like `Vec<T>` or `HashMap<K, V>`. A Rust
data structure that is generic over a reference-lifetime conventionally uses an
apostrophe followed by a single lower-case letter for the lifetime variable,
like `Something<'a>`.
Previously, Kakoune would highlight "'a>" as the lifetime parameter; with this
change Kakoune highlights "'a" and leaves the closing ">" alone.
The :format command is often called from a BufWritePre hook to format the
current buffer, however the :format command itself calls `:write` to store the
buffer in a temporary location, potentially causing an infinite recursion.
If we disable hooks while running :format, there's no danger of that occurring.
Changes:
- Highlight float literals with float type suffixes (nf64 and nf32)
- Make module items use the module color
- Highlight macro variables $variable
- Highlight lifetimes
- Highlight u128 and i128
- Highlight character literals (e.g. 'a')
- Highlight dyn keyword (will in the future be used for trait objects)
Previously, due to a typo, Kakoune would highlight backtick spans from the first backtick to the last backtick in a paragraph, no matter how many backticks were in between. Now spans correctly stop at the first backtick after the opening backtick.
even though tmux 2.7 is installed.
The problem is that
```
expr "$(tmux -V)" : 'tmux \([0-9]*\|master\)'
```
fails on FreeBSD. It works fine with GNU expr.
Replace the expression with cut(1) and a simple parameter expansion
which should hopefully work fine on any POSIX system.

set-face now takes a scope argument, and faces can be overridden on
a buffer or window basis.
colorscheme apply on global scope, which should be good enough for
now.
Fixes#1411
Instead of starting the default shell and sending it text (hoping
it will support POSIX like shell syntax), just use the `env` utility
to set the correct environment and exec kakoune.
- Added <?php and ?> tags, and highlight everything outside as html
- Highlight documentation comments and @fields
- Added basic string interpolation highlighting
Letting any character to be escaped is error prone as it looks like
\l could mean [:lower:] (as it used to with boost) when it only means
literal l.
Fix the haskell.kak file as well.
Fixes#1945
Previously, two underscore characters in a document would mark the entire
space between them as italic, no matter how far apart. Now we only accept a
single consecutive newline within an inline-formatted span, so hard-wrapped
documents will still format nicely but stray characters won't mess up your
entire document.
Note that the highlighter for backtick-enclosed spans was modified,
even though it's redundant with the code-block highlighting introduced
in 5bc62c694.
As well as the traditional `[text](url)` syntax, Markdown allows the text to
be followed by a tag in square brackets. If the text is followed by nothing
at all, then the tag for that link is the text itself. The actual URL
is supplied later in the document, like a footnote at the bottom of the page:
Some text with [a link][tag] and [another link].
[tag]: http://www.example.com/link1
[another link]: http://www.example.com/link2
This adds the "link" face to the URL in such footnote lines.
Makes all the suggestions on the completion menu have the same format:
{type}{suggestedWord}{extra description}
the type column is aligned to 6 characters wide (and aligned to the right),
to allow the suggestion to be easily visually detectable and, as a bonus,
the type too.
For example, a bit of menu would look like this:
fn stdout() -> Stdout
trait BufRead: Read
struct BufReader<R>
Type is one of the following:
- fn
- enum
- mod
- trait
- struct
It also trims the module extra bits to only 30 characters long (it can be a lot longer than that)
When AWK processes the racer response, it adds a trailing ':' that
kakoune completion expects to lead to a row having an 'a|b|c' shape,
but it's empty instead. Removing the extra ':' allows the racer
complation to actually work.
There does not seem to be any reasonable use cases of not collapsing
jumps when the input is not comming from the user. Always collapse
them.
It could make sense to move jump collapsing out of context_wrap as
in general any action not comming directly from the user should
collapse them, at the moment a comment or mapping will not collapse
jumps, which is unfortunate.
The use of `%{...%reg{...}}` was not being expanded correctly, as
the enclosing %{...} prevents the internal %expand{...} from being
considered.
The introduction of an additional command allows us to bypass
quoting hell as the expansion of %reg{5} could contain arbitrary
text.
With the introduction of -match-capture for the lua region highlighter,
the string closing regex had spurious captures that were not going to
match.
Fixes#1850
This commit avoids false positives when highlighting literals such as
`$window`, which is a regular variable but still highlighted as a
special value.
Special highlighting of variables that start with a dollar sign `$`
was also removed, as not all variables start with a dollar sign,
and we don't have a reliable way yet to detect variables.
unsetting static_words whenever any buffer filetype is set to non ocaml
is wrong, it breaks static_words for every filetype whose filetype hook
run before the ocaml ones.
Block comments in Lua were broken, apparently due to the opening
sequence being interpreted as a line comment. Changing the order in the
highlighter seems to fix this issue.
Fixes#1735
We need \K to not interfer with languages own interpretation of ` like multiline strings in javascript
We need \b in e.g. java\b otherwise it blocks javascript
I couldn't get the bare ``` to not block the other highlighters when introducing \K any other way than negative lookahead of all possible highlighers
Commit 870d2d22d7 introduced a regression
in the highlighting of qualified Haskell variables, such as `Foo.bar`.
After that commit `Fo` was highlighted as a constructor (note, not
`Foo`, just `Fo` without the trailing `o`). This restores the original
behavior.
- Ensure ranger opens with the currently focused client tty if multiple screen clients are connected to the same session.
- Ensure args are passed to ranger correctly.
- Ensure command-line args are passed to ranger correctly. (Only strict long format works e.g. `ranger --cmd="echo foo"`)
- Change the current directory because `screen -X` uses screen's cwd not kakoune's.
- Use heredoc to make escaping and quoting easier to debug and slightly less unpredictable.
- Use ranger's `--choosefiles` option instead of mapping keys and having to do multiple levels of escaping and quoting of args esp. command-line args which were unusable in `screen -X eval`.
- Remove screen region when user quits ranger.
- The proper way to do this would be to switch focus to the target client's region but GNU Screen offers no obvious way to do that.
- Remove screen region after client is closed.
- Assumed: Kak server runs in screen.
- Hack: kak sets `/proc/self/fd/0 -> /dev/null`. Get the client process tty because Screen needs to know the controlling terminal. Else Screen will use the last known tty and will open new windows on a different terminal if one is connected.
As well as ordinary `//` line-comments, Rust regards `///` comments
as documentation applying to the following item, and `//!` comments as
documentation applying to the enclosing item, so we should copy those
to new lines, too.
* move most of the kakoune implementation outside of the shell scope
to avoid unnecessary escaping
* let kakoune do the option expansions to avoid injection of special
characters
* split block commenting options into two and do the < to <lt>
conversion directly
* show error messages directly in the buffer rather than in *debug*
Fixes#1600 and #875
That means we can now have highlighters active at global, buffer, and
window scope. The add-highlighter and remove-highlighter syntax changed
to take the parent path (scope/group/...) as a mandatory argument,
superseeding the previous -group switch.
boost regex tolerates non-escaped special characters, and escaped
non-special characters. Standardize on stricter syntax, where
special characters must be escaped, and non-special characters must
not.
this uses 'export' to set $TMPDIR instead; fish provides an 'export'
function for bash-compatibility, so this should work for both shells.
note that prior to this change, opening new panes with fish did not
work, as fish does not support `FOO=1 bar` syntax.
- the file was edited with a different editor/program or
- kak didn't restore a backup or
- if old backups weren't purged or
- if autorestore wasn't loaded (e.g. `kak -n`) after backups were generated.
Sometimes the implementation of `man` will display errors, e.g.
```
<standard input>:4808: warning [p 54, 13.2i]: can't break line
```
Those errors are harmless but are still reported on the debug buffer,
so we hide them by redirecting the standard error stream to /dev/null.
When using the `man` filetype to make use of the text highlighters
of the `man.kak` script, the documentation pages inherit from the
window resizing hooks that won't work on `doc` buffers.
Fixes#1591
Highlighting perl regex patterns with regular expressions (with
highlighters) caused several misses that made most of the file
unreadable. This commit makes `perl.kak` not try to highlight
those patterns in the code, and also addresses issues with string
highlighting.
Import keywords are put in keyword face instead of meta face.
This leaves room for pragmas and macros to be in the meta face.
Operator keywords are put in keyword face too.
Finally, expression keywords are put in face attribute.
Previously, if you opened a new line after an underlined heading (what
the CommonMark spec calls a "Setext heading") or inserted a newline into
a line that started with `**strong emphasis**` the Markdown autoindent
hook would assume the leading symbols were list bullets and paste them
at the beginning of the new line.
However, the CommonMark specification says that list bullets must be
followed by at least one horizontal whitespace character, so Setext
heading underlines and strong emphasis are not valid list bullets and
should not be matched by the autoindent pattern.
This commit changes the regex that selects the pastable prefix of the
previous line so that it must match either:
- One or more `>` characters with optional whitespace between them
(a blockquote prefix), optionally followed by a list bullet; or
- An optional blockquote prefix and a list bullet
Since we don't strictly need either the blockquote prefix nor the list
bullet, we could concievably just make both optional... but for lines
without either, the regex would find a zero-length match, and for the
purposes of copy/paste Kakoune treats that as a one-character match.
Therefore, the regex is written to fail if neither pattern is found.
When used just after grepping, grep-next-match ended up jumping to
the second match, as `0g` is the same as `g`.
The fix itself is pretty ugly, a better one might be to distinguish
the `0` count from no count given, so that `0g` could fail with
"no such line" or similar.
Looking up the man page for `index` was failing on systems using
GNU/coreutils. The `:man` command matched whatever page it was given with
the `expr` utility. This tool behaves as expected when it follows strictly
the POSIX standard but the GNU implementation introduces additional commands
(including `index`), about which the standard states:
```
The use of string arguments length, substr, index, or match produces unspecified results.
```
As a result, parsing the man page number is now implemented with pure
shell expansions, to avoid triggering an undefined behavior when the topic
searched is one of the keywords above.
The previous implementation used to replace the contents of the buffer with
whatever the `formatcmd` was returning, regardless of the exit code of the
command, which led to the buffer being wiped out on error.
This commit does the formatting in a temporary file, and only replaces the
current buffer with the contents of the -formatted- temporary file if the
`formatcmd` returned successfully.
Fixes#1357
this uses the string opening regex from the c-family highlighter to prevent
highlighting the rest of the file as a string on encountering the character
literal '"'
Generalize this option type, which is a timestamped list of
<line number>|<arbitrary string>. That way this type is not strongly
coupled with the flag-lines highlighter, and can be reused for other
use cases.
range-faces are now used to replace-range highlighters, where the string
part is not interpretted as a face but as a display line, so the name was
not relevant anymore.
These are less useful with more static words, and they are
woefully incomplete: no support -docstring for map, set
uses the variable face, but there is no corresponding
highlighter for decl or %opt{..}.
`tmux` will start new processes (e.g. when creating panes or windows)
with the same environment it was started with, which means that if the
$TMPDIR variable was overriden for the kakoune server from within
`tmux`, newly created panes/windows won't have access to the server
socket to sustain a session.
This commit fixes the issue by always exporting the $TMPDIR variable
from the parent `tmux` environment to the new processes.
Fixes#1319
