This patch centralises the loading of windowing environments, in order
to ensure that by default only a single module is loaded, rather than
the current code which can load multiple potentially incompatible
modules; and in order to provide the user with more control over the
loading of windowing modules.
The patch introduces a new str-list option `windowing_modules` which
defines an ordered list of windowing modules to attempt to load. Modules
are loaded in the order specified in the list until a module loads
without error, at which point the process finishes.
When loaded each windowing module tests the environment to determine
whether it should load (e.g. the tmux module tests to see if it's being
run within a tmux session), and if it determines that it should then it
completes its loading without error. If it doesn't detect an appropriate
environment then it returns an error, and the module loading logic tries
the next module.
The user can override the default `windowing_modules` list to specify
their preferred modules (i.e. they can put kitty ahead of tmux if that's
their preference, or they can leave out the x11 modules alltogether). In
addition, if the `windowing_modules` option is an empty list this
bypasses the environment detection logic completely, and allows the
modules to be loaded manually - this allows a user to replace the
windowing module loading logic with their own manual set up.
* Add r7rs functions, keywords, etc.
* Add highlighting for decimal, hex, octal, binary constants
* Add missing word characters
* Resolve several issues with word boundaries
Similarly to the <semicolon> key, make it easier to write
`:execute-keys` commands by replacing <percent> with `%`.
Highlighters can keep escaping the sign when regular expressions are
not quoted, but built-in scripts that use `%` as an editing primitive
have been modified to use the named key, for clarity.
This commit renames `lint-enable` into `lint-show-diagnostics`,
makes it hidden, and calls it automatically after diagnostics have
been recovered by `:lint-cleaned-selections`.
The `lint-disable` command becomes `lint-hide-diagnostics`.
The concept of "enabling" diagnostics was inherited from the Clang
support script, but in that case it's not clear why calling `:lint`
should do the work but not render it (similarly to `:spell`).
The `lint-show` command was also renamed into a more descriptive
`lint-show-current-line`.
Ranges specified with a +<length> were inconsistent, with +0 meaning
an empty range, while +1 meant a two character long range (first character
+ the following one). Change that to mean a single character.
Fixes#3479
This commit removes declarations and mentions to the built-in `bold`
and `italic` faces.
While they could be a user-friendly way of customising how tokens
are emphasised in Markdown documents (similarly to the
`$LESS_TERMCAP_*` environment variables for `man` pagers), most other
markup languages do not have the concept of "strong" and "emphasis"
but refer directly to the font style/weight.
The faces were also not even set by default to highlight as their
names implied, so having markup language support scripts directly
use the +b and +i face attributes is more consistent.
Highlight every character between brackets, including more
brackets. This allows alternative constructs in INI files such as:
```
[section]
[[subsection]]
```
This commit also only applies the appropriate face on the section
name itself, not the entire line (including hypothetical surrounding
whitespace characters).
This adds support for the Eex templating that is used in the Phoenix
web framework. Eex files include HTML and Elixir code, and Elixir files
can include Eex in string literals marked with the `~L` prefix.
Additionally this unbreaks `"""` string literals, which did not work because
`"` was matched before `"""`
