| + | ======Overview:====== | ||
| + | before(//count// //chars// //text//) | ||
| + | |||
| + | ======Technical:====== | ||
| + | The before() function returns the part of //text// before the //count//th instance of any of the characters in //chars//. | ||
| + | |||
| + | The //chars// argument may contain multiple characters. If it contains a space, you should surround it with double quotes (which won't count). | ||
| + | |||
| + | If //text// does not contain //count// instances of any of the characters in //chars//, or if //count// is 0, then it returns the empty string. | ||
| + | |||
| + | If //count// is a negative number, the characters are counted from the end of the string. | ||
| + | |||
| + | ======Defined Behaviors:====== | ||
| + | ^ Call ^ Return Value ^ Because ^ | ||

| + | | before(-2 / /usr/local/bin/epic) | /usr/local | | ||
| + | | before(5 / /usr/local/bin/epic) | the empty string | (there are not 5 /'s in the string)| | ||
| + | | before(/ /usr/local/bin/epic) | the empty string | (//count// defaults to 1) | | ||
| + | | before(0 ! hop!user@host) | the empty string | (the //count// argument is 0)| | ||
| + | | before(1 @ /usr/local/bin/epic) | the empty string | (there is not 1 @'s in the string)| | ||
| + | | before(/usr/local/bin/epic) | the empty string | (argument error -- there are not enough words)| | ||
| + | | before() | the empty string | (no params) | | ||
