Arrays: Difference between revisions

Line 3,701:

LIL, like Tcl, doesn't manage arrays as such. Indexed lists are used in LIL. The '''list''' command creates a list from the remaining arguments in the statement. The '''index LIST NUM''' command returns the NUM'th item in the list, starting from zero. Lists are copied on assignment. The array-ish functions and operators would be

- index LIST NUM, returning the NUM'th item

* index LIST NUM, returning the NUM'th item

- count LIST, returning the number of items in the list

* count LIST, returning the number of items in the list

- indexof LIST VAL, returning the offset from zero position of where VAL is found in LIST, or an empty string

* indexof LIST VAL, returning the offset from zero position of where VAL is found in LIST, or an empty string

- filter VARNAME LIST EXPRESSION, returning a new list of filtered items matching EXPRESSION, with the value under test in VARNAME.

* filter VARNAME LIST EXPRESSION, returning a new list of filtered items matching EXPRESSION, with the value under test in VARNAME.

- list ..., creating a list from remaining word tokens in the statement.

* list ..., creating a list from remaining word tokens in the statement.

- append LIST VAL (list VAL values are appended as single items to the given LIST)

* append LIST VAL (list VAL values are appended as single items to the given LIST)

- slice LIST FROM-NUM TO-NUM

* slice LIST FROM-NUM TO-NUM

- foreach VARNAME LIST CODE

* foreach VARNAME LIST CODE

- charat STRING NUM, indexing a string for characters

* charat STRING NUM, indexing a string for characters

- codeat STRING NUM, indexing a string for the character byte code

* codeat STRING NUM, indexing a string for the character byte code

- lmap LIST VARNAME..., maps the list items to the given variable names, in the order given.

* lmap LIST VARNAME..., maps the list items to the given variable names, in the order given.
