The /tokenize command replaces the existing $0 through $N'th tokens, filling $1 $2 ... $N identifiers with portions of a string, divided into tokens based on the location of the <C> delimiters. It also fills $0 with an integer containing the number of tokens filled from the string.

Synopsis

/tokenize <C> <text>

Switches

None

Parameters

• <C> - The code point ($asc() value) 1-65535 of the character used as the delimiter (If the codepoint is not present within <text> the entire string is filled into $1)
• <text> - The string of <C> delimited tokens which will fill the $N identifiers

Example

Typing the following into the editbox returns a result:

//tokenize 58 one:two:three | echo -a Result of $!2: $2
;$asc(:) == 58

Result of $2: two

More examples using different delimiters:

//tokenize 32 Hello, how are you? | echo -a Result of $!3: $3
;$chr(32) is a space

Result of $3: are

//tokenize 44 This is, a comma delimited, list. | echo -a Result of $!1: $1

Result of $1: This is

Tokenizing follows the same rules as used by $gettok() and the other $*tok identifiers, where it strips leading, trailing, and consecutive delimiters. Consecutive delimiters does not result in a $null token:
//tokenize 64 @1@@2@@3@@ | echo -a (1) $1 (2) $2 (3) $3 (4) $4
returns: (1) 1 (2) 2 (3) 3 (4)
This means that tokenizing by other than space 32 can result in tokens having leading or trailing spaces causing tokens to be treated differently:
//tokenize 46 1 .2 .3 | echo -a $len($2) / $asc($mid($2,2)) | echo -a $!2 value is $2 which is $iif($2 isnum,numeric, non-numeric)
returns: $2 value is 2 which is non-numeric
 
'''Note:''' because this is a /command not an $identifier, leading trailing or consecutive spaces are removed from <text> before (but not after) the tokenizing. But if tokenizing by 32, the leading and trailing spaces are also removed from the created $1 ... $N'th tokens.
 
Using /tokenize destroys the existing $1- tokens, so if you still need those, you should save them to a variable or use tokenize within another alias. If you use tokenize within an alias called from another alias, using tokenize does not affect the $1- values seen by the original alias.
//tokenize 32 the quick brown fox jumps over the lazy dog | while ($1) { echo -a $1- | tokenize 32 $2- }
 
//tokenize 32 1.0 2.0 3.0 4.0 | echo -a changes from: $1- | if (. isin $2) tokenize 32 $1 $int($2) $3- | echo -a changes to: $1-
returns: 1.0 2 3.0 4.0
