From fad15f79b1230b3076be515d6894c8919562809b Mon Sep 17 00:00:00 2001 From: mitchell Date: Sat, 25 Apr 2020 16:26:31 -0400 Subject: Reformatted Lua LPeg lexers and added new convenience functions and pattern. `lexer.range()` replaces `lexer.delimited_range()` and `lexer.nested_pair()`. `lexer.to_eol()` replaces `patt * lexer.nonnewline^0` constructs. `lexer.number` replaces `lexer.float + lexer.integer`. Also added unit tests for lexer functions. --- lexlua/actionscript.lua | 13 ++++++------- 1 file changed, 6 insertions(+), 7 deletions(-) (limited to 'lexlua/actionscript.lua') diff --git a/lexlua/actionscript.lua b/lexlua/actionscript.lua index 69dcc80fc..401ae77c0 100644 --- a/lexlua/actionscript.lua +++ b/lexlua/actionscript.lua @@ -33,19 +33,18 @@ lex:add_rule('type', token(lexer.TYPE, word_match[[ lex:add_rule('identifier', token(lexer.IDENTIFIER, lexer.word)) -- Strings. -local sq_str = lexer.delimited_range("'", true) -local dq_str = lexer.delimited_range('"', true) -local ml_str = '')^0 * ']]>' +local sq_str = lexer.range("'", true) +local dq_str = lexer.range('"', true) +local ml_str = lexer.range('') lex:add_rule('string', token(lexer.STRING, sq_str + dq_str + ml_str)) -- Comments. -local line_comment = '//' * lexer.nonnewline^0 -local block_comment = '/*' * (lexer.any - '*/')^0 * P('*/')^-1 +local line_comment = lexer.to_eol('//') +local block_comment = lexer.range('/*', '*/') lex:add_rule('comment', token(lexer.COMMENT, line_comment + block_comment)) -- Numbers. -lex:add_rule('number', token(lexer.NUMBER, (lexer.float + lexer.integer) * - S('LlUuFf')^-2)) +lex:add_rule('number', token(lexer.NUMBER, lexer.number * S('LlUuFf')^-2)) -- Operators. lex:add_rule('operator', token(lexer.OPERATOR, S('=!<>+-/*%&|^~.,;?()[]{}'))) -- cgit v1.2.3
