Yorick Function Reference
Manipulating Strings
Yorick type string is a pointer to a 0-terminated array of
char.
A string with zero characters - "" - differs from a zero pointer
- string(0). A string variable s can be converted
to a pointer to a 1-D array of char, and such a pointerp can be converted back to a string:
p=pointer(s); s=string(p);
These conversions copy the characters, so you can't use the pointer p to
alter the characters of s. The strchar function directly
converts between string and char data.
Given a string or an array of strings s:
strlen(s ) number of characters in each element of s
strpart(s, rng) returns substring rng of s
strfind(pat, s) returns rng where pat occurs in s
strgrep(pat, s) regular expression version of strfind
strword(s, delims) returns rng of words in s
streplace(s, rng, to) replaces rng of s by to
The strfind, strgrep, and strword functions
return rng lists suitable as inputs to strpart or
streplace. Other string manipulation functions include
strmatch, strglob, strcase, and strtrim.
