+ | # $EPIC: wordtoindex.txt, | ||
+ | ======Synopsis: | ||
+ | $__wordtoindex__(< | ||
+ | |||
+ | ======Technical: | ||
+ | * If the < | ||
+ | * If < | ||
+ | * If < | ||
+ | * There is only one space that separates < | ||
+ | * The return value is the character position (as would be returned by $[[index]]() and could be used by $[[right]]() et al) of the first character in the < | ||
+ | * < | ||
+ | |||
+ | ======Practical: | ||
+ | The most practical use of this function is to permit you to find the | ||
+ | beginning position of a word in a string, especially after you have had | ||
+ | to change the length of some of the words in the list. This technique is | ||
+ | most obviously used by tab completion scripts which will take the input | ||
+ | line ($L), the cursor position ($[[curpos]]()), | ||
+ | function to figure out where the cursor is. Then they rewrite the input | ||
+ | line using tab completion, and use $wordtoindex() to figure out where the | ||
+ | cursor is supposed to go after the input line has been rewritten. | ||
+ | |||
+ | ======Returns: | ||
+ | The number of characters before the beginning of the < | ||
+ | in < | ||
+ | |||
+ | ======Examples: | ||
+ | < | ||
+ | $wordtoindex(2 foo bar blah) | ||
+ | $wordtoindex(999 foo bar blah) | ||
+ | $wordtoindex(-1 foo bar blah) returns 0 | ||
+ | </ | ||
