Display better snippet for invalid char literal Given this code: fn main() { let _ = 'abcd'; } The compiler would give a message like: error: character literal may only contain one codepoint: '; let _ = 'abcd'; ^~ With this change, the message now displays: error: character literal may only contain one codepoint: 'abcd' let _ = 'abcd' ^~~~~~ Fixes #30033 2016-01-07 16:12:28 +00:00			`//`

testsuite: merge some lexer testcases Now that the lexer is more robust, these tests don't need to be in separate files. Yay! 2014-06-16 14:12:44 -07:00			`static c: char =`
introduce unescape module Currently, we deal with escape sequences twice: once when we lex a string, and a second time when we unescape literals. This PR aims to remove this duplication, by introducing a new `unescape` mode as a single source of truth for character escaping rules 2019-04-25 11:48:25 +03:00			`'● //~ ERROR: unterminated character literal`
Make most lexer errors non-fatal Most errors that arise in the lexer can be recovered from. This allows for more than one syntax error to be reported at a time. 2014-05-23 15:20:46 -07:00			`;`
