int search( list X, string pattern)
The search function returns the index of the first matching instance of pattern in the specified list. If there is no match, it returns -1.
The first element in the list is index:0.
The following example prints the index number for "cory", which is 1:
a=search({"jamie","cory","robyn"},"c*"); print(a); | j* |
j followed by any number of characters. |
| j*e |
j followed by any number of characters, ending with an e. |
| [jJ]* |
Upper or lower case j followed by any number of characters. |
| [a-z] |
Any lower case character. |
| [^a-z] |
Any character except lower case characters. |
|
j followed by a single character. |
list split ( string X [, string delimiter] string omit_empty_elements )
The split function is the opposite of join. It constructs a list by concatenating the strings into a list. It separates each element in the list with a delimiting character, which can be any character from the delimiter string. The default for delimiter is any white space character.
A sequence of two or more contiguous delimiter characters in the parsed string is considered to be a single delimiter. Delimiter characters at the start or end of the string are ignored.
The omit_empty_elements argument defaults to true. If specified and is false, the empty elements are not omitted from the resulting list.
The following example returns the list: {"jamie", "cory", "robyn"}
a = split( "jamie, cory, robyn", ", ")
list splitsubst( string X, string delimiter )
The splitsubst function splits a string X into a list. This function is similar to the split function except that the delimiter contains the entire delimiter string.
The following example returns the list: "john","jane,james"
a = splitsubst( "john,,jane,james", ",," )
