* Adapt the char literal highlighter from c-family.kak
* Fix line comment adjacent to char literal not being highlighted
* Fix single quote terminating a double quote string
* Fix keywords in comments being highlighted
* Highlight Nim's escape sequences for strings
* Highlight common comment tags
* Add on/off to the highlighted boolean values
* Remove redundant regex highlighter for comments
* Fix autoindent indenting lines more than it should
Before:
```nim
type
MyType = tuple
myint: int # This line needs to be indented manually
```
After:
```nim
type
MyType = tuple
myint: int # Lines after 'tuple' are now indented automatically
```
Make sure decorators are on their own line, and don't stop highlighting at
the first dot when they are imported, e.g.
```
import enum
@enum.unique
class A(enum.Enum):
…
```
Ideally highlighting shouldn't stop at the first parenthesis either
(e.g. `@foo(['1'])`), but the current code somewhat highlights the contents
of the parens already, which is good enough in most cases.
This attempts to support a simple formatting and intentation style for
plain sh syntax (and other sh-compatible code which doesn't stray too
far from portable sh).
The complexity of sh syntax means that we have to be opinionated -
attempting to be more flexible would require extensive context
awareness, and would require something more akin to a proper
autoformatting tool or a language server.
The formatting style used here makes use of vertical whitespace as the
primary delimiter, so that code ends up looking like this:
if [ $foo = "bar" ]; then
thing1
else
thing2
fi
for i in foo bar baz; do
thing1
thing2
done
case "$foo" in
bar) thing1;;
baz)
thing1
thing2
;;
esac
Since the formatting style used is very opinionated the 'sh_auto_indent'
option can be used to disable auto-indentation, with the default set to
'no'.
