## String literals
|
|
## TODO: multiline backtick and doublequote string. (Unlikely possible at all with nano.)
|
|
### DoubleQuotedString
|
|
color constant ""(\\.|[^"])*""
|
|
|
|
### WysiwygString
|
|
color constant (s) "r".*?""
|
|
color constant "`[^`]*`"
|
|
|
|
### HexString
|
|
color ,constant "x"([[:space:]]*[[:xdigit:]][[:space:]]*[[:xdigit:]])*[[:space:]]*""
|
|
|
|
### DelimitedString
|
|
color constant "q"\(.*\)""
|
|
color constant "q"\{.*\}""
|
|
color constant "q"\[.*\]""
|
|
color constant "q"<.*>""
|
|
color constant (s) "q"[^({[<"][^"]*$.*?^[^"]+""
|
|
color constant "q"([^({[<"]).*""
|
|
|
|
### TokenString
|
|
### True token strings require nesting, so, again, they can't be implemented accurately here.
|
|
### At the same time, the intended purpose of token strings makes it questionable to highlight them as strings at all.
|
|
## color ,magenta (s) "q\{.*?\}"
|
|
|
|
## Comments
|
|
## NB: true nested brightblacks are impossible to implement with plain regex
|
|
color comment "//.*"
|
|
color comment (s) "/\*.*?\*/"
|
|
color comment (s) "/\+.*?\+/"
