It allows - you extract tokens one at a time from a string of characters. The - characters used for white space, for break characters, and for quotes - can be specified. Also, characters in the string can be preceded by - a specifiable escape character which removes any special meaning the - character may have. - - There are a lot of formal parameters in this subroutine call, but - once you get familiar with them, this routine is fairly easy to use. - "#define" macros can be used to generate simpler looking calls for - commonly used applications of this routine. - - First, some terminology: - - token: used here, a single unit of information in - the form of a group of characters. - - white space: space that gets ignored (except within quotes - or when escaped), like blanks and tabs. in - addition, white space terminates a non-quoted - token. - - break character: a character that separates non-quoted tokens. - commas are a common break character. the - usage of break characters to signal the end - of a token is the same as that of white space, - except multiple break characters with nothing - or only white space between generate a null - token for each two break characters together. - - for example, if blank is set to be the white - space and comma is set to be the break - character, the line ... - - A, B, C , , DEF - - ... consists of 5 tokens: - - 1) "A" - 2) "B" - 3) "C" - 4) "" (the null string) - 5) "DEF" - - quote character: a character that, when surrounding a group - of other characters, causes the group of - characters to be treated as a single token, - no matter how many white spaces or break - characters exist in the group. also, a - token always terminates after the closing - quote. for example, if ' is the quote - character, blank is white space, and comma - is the break character, the following - string ... - - A, ' B, CD'EF GHI - - ... consists of 4 tokens: - - 1) "A" - 2) " B, CD" (note the blanks & comma) - 3) "EF" - 4) "GHI" - - the quote characters themselves do - not appear in the resultant tokens. the - double quotes are delimiters i use here for - documentation purposes only. - - escape character: a character which itself is ignored but - which causes the next character to be - used as is. ^ and \ are often used as - escape characters. an escape in the last - position of the string gets treated as a - "normal" (i.e., non-quote, non-white, - non-break, and non-escape) character. - for example, assume white space, break - character, and quote are the same as in the - above examples, and further, assume that - ^ is the escape character. then, in the - string ... - - ABC, ' DEF ^' GH' I ^ J K^ L ^ - - ... there are 7 tokens: - - 1) "ABC" - 2) " DEF ' GH" - 3) "I" - 4) " " (a lone blank) - 5) "J" - 6) "K L" - 7) "^" (passed as is at end of line) - - - OK, now that you have this background, here's how to call "tokenizer": - - result=tokenizer(flag,token,maxtok,string,white,break,quote,escape, - brkused,next,quoted) - - result: 0 if we haven't reached EOS (end of string), and - 1 if we have (this is an "int"). - - flag: right now, only the low order 3 bits are used. - 1 => convert non-quoted tokens to upper case - 2 => convert non-quoted tokens to lower case - 0 => do not convert non-quoted tokens - (this is a "char"). - - token: a character string containing the returned next token - (this is a "char[]"). - - maxtok: the maximum size of "token". characters beyond - "maxtok" are truncated (this is an "int"). - - string: the string to be parsed (this is a "char[]"). - - white: a string of the valid white spaces. example: - - char whitesp[]={" \t"}; - - blank and tab will be valid white space (this is - a "char[]"). - - break: a string of the valid break characters. example: - - char breakch[]={";,"}; - - semicolon and comma will be valid break characters - (this is a "char[]"). - - IMPORTANT: do not use the name "break" as a C - variable, as this is a reserved word in C. - - quote: a string of the valid quote characters. an example - would be - - char whitesp[]={"'\""); - - (this causes single and double quotes to be valid) - note that a token starting with one of these characters - needs the same quote character to terminate it. - - for example, - - "ABC ' - - is unterminated, but - - "DEF" and 'GHI' - - are properly terminated. note that different quote - characters can appear on the same line; only for - a given token do the quote characters have to be - the same (this is a "char[]"). - - escape: the escape character (NOT a string ... only one - allowed). use zero if none is desired (this is - a "char"). - - brkused: the break character used to terminate the current - token. if the token was quoted, this will be the - quote used. if the token is the last one on the - line, this will be zero (this is a pointer to a - "char"). - - next: this variable points to the first character of the - next token. it gets reset by "tokenizer" as it steps - through the string. set it to 0 upon initialization, - and leave it alone after that. you can change it - if you want to jump around in the string or re-parse - from the beginning, but be careful (this is a - pointer to an "int"). - - quoted: set to 1 (true) if the token was quoted and 0 (false) - if not. you may need this information (for example: - in C, a string with quotes around it is a character - string, while one without is an identifier). - - (this is a pointer to a "char"). -*/ - -/* states */ - -#define IN_WHITE 0 -#define IN_TOKEN 1 -#define IN_QUOTE 2 -#define IN_OZONE 3 - -int _p_state;
