Detailed Description
This class defines a lexer using file extensions, syntax colouring and comment definitions.
This lexer is one of the Scintilla lexers. The lexers are read by and kept in the wex::lexers class.
Member Function Documentation
◆ attrib()
| int wex::lexer::attrib | ( | const std::string & | name | ) | const |
Returns specified config attrib.
The value depends on attrib, but is -1 if not present.
◆ clear()
| void wex::lexer::clear | ( | ) |
Clears lexer and applies it to stc if available.
The is ok member is set to false.
◆ comment_complete()
| const std::string wex::lexer::comment_complete | ( | const std::string & | comment | ) | const |
Returns a string that completes specified comment, by adding spaces and a comment end at the end.
If the comment end string is empty, it returns empty string.
◆ keywords_string()
| const std::string wex::lexer::keywords_string | ( | int | keyword_set = -1, |
| size_t | min_size = 0, |
||
| const std::string & | prefix = std::string() |
||
| ) | const |
Returns the keywords as one large string,.
- Parameters
-
keyword_set if keyword_set -1 take all the sets, otherwise take the specified set. min_size if min_size 0, use all keywords, otherwise use keywords with minimim size prefix prefix keyword should start with
◆ operator=()
Assignment operator.
The stc component is assigned only if it is nullptr.
◆ set()
| bool wex::lexer::set | ( | const lexer & | lexer, |
| bool | fold = false |
||
| ) |
Sets lexer to specified lexer, and applies it to stc if present.
Returns true if a scintilla lexer has been set.
