split


Description:

public string[] split (string delimiter, int max_tokens = 0)

Splits a string into a maximum of max_tokens pieces, using the given delimiter.

If max_tokens is reached, the remainder of string is appended to the last token.

As an example, the result of g_strsplit ("gchar:agchar:bcgchar::d:", ":", -1) is a null-terminated vector containing the six strings "", "a", "bc", "", "d" and "".

As a special case, the result of splitting the empty string "" is an empty vector, not a vector containing a single string. The reason for this special case is that being able to represent a empty vector is typically more useful than consistent handling of empty elements. If you do need to represent empty elements, you'll need to check for the empty string before calling split.

Example: Split a string:

public static int main (string[] args) {
string doctors_str = "William Hartnell, Patrick Troughton, Jon Pertwee, Tom Baker, Peter Davison, Colin Baker, Sylvester McCoy";

// Output:
// ``'William Hartnell'``
// ``'Patrick Troughton'``
// ``'Jon Pertwee'``
// ``'Tom Baker'``
// ``'Peter Davison'``
// ``'Colin Baker'``
// ``'Sylvester McCoy'``
string[] doctors = doctors_str.split (", ");
foreach (unowned string str in doctors) {
print ("'%s'\n", str);
}

// Output:
// ``'Alistair'``
// ``'Gordon Lethbridge-Stewart'``
string line = "Alistair Gordon Lethbridge-Stewart";
string[] lines = line.split (" ", 2);
foreach (unowned string str in lines) {
print ("'%s'\n", str);
}

return 0;
}

valac --pkg glib-2.0 string.split.vala

Parameters:

delimiter

a string which specifies the places at which to split the string. The delimiter is not included in any of the resulting strings, unless max_tokens is reached.

max_tokens

the maximum number of pieces to split string into. If this is less than 1, the string is split completely.

string

a string to split

Returns:

a newly-allocated null-terminated array of strings. Use strfreev to free it.
