Hi all, I recently dropped a post titled "WORD # and syntax files", for help about highlighting a WORD followed by some symbol. The help I received, here and by direct mail, helped me in understanding why I couldn't achieve the desired results, because the formulation for selecting WORD# had been preceded by a similar request through "syn keyword", and this covered the "syn match" I was operating on WORD.
Just to be clear, this syntax file tries to emulate the DEC-10 BASIC compiler syntax (1974). Now, what I did resolve (with your active help) was for commands that accept a channel identifier, followed by anything else; e.g.: WRITE #1, A$ PRINT :3, A,B,C INPUT 2, N$ READ :5, A$ the # symbol (that is not mandatory) means "sequential file", and the : symbol (which must be written) is for random access files. Now, in the DEC-10 BASIC, there are commands that don't accept arguments after a channel identifier, but accept channel identifiers as arguments: RESTORE 2, #4, :5 RESTORE #2; 4, :5 RESTORE :3; :4, 3 The separator is a comma or a semicolon, the # (occasionally missing) is for sequential, : is for random. My purpose is to highlight the "RESTORE + channel" plus any other channel arguments left, but leaving the separators (commas and semicolons) not highlighted. I tried, for RESTORE, with the following line: syn match File "RESTORE\s*[#:]\s*\d\+[\s*[,;]\+\s*[#:]*\s*\d\+\s*]*" that tries to grab RESTORE plus the first argument and then all other arguments in turn (if any). But this doesn't work as expected, and above all, with this model I get commas and semicolons highlighted. Another model was to grab all arguments by their own with syn match File "[#:]\d\+" and RESTORE by its own, but this doesn't solve the fact that RESTORE 3 (perfectly legal, in BASIC) has a number as argument, that is not highlighed (it should be written #3 for this). If I write syn match File "[#:]*\d\+" I of course get all numbers highlighted as well! Any help? Any ideas? Please, answer to tbin at libero dot it, if you want it, or directly to this thread. Thanks in advance, mates! -- Antonio -- You received this message from the "vim_use" maillist. For more information, visit http://www.vim.org/maillist.php
