![]() ![]() For example, if you had an array of items, you could sort it " by autosell_price(value)". by value", but many useful things can be done with the use of a more complex keyExpr - the only real restriction is that the expression should not modify the object you're sorting. The most basic form of sorting would therefore be " sort. The value of the keyExpr is used as the sort key typically it would be an int or string, but can be any ASH type that can be compared via "<" and the other relational operators. ![]() It is evaluated once for every entry in the aggregate, in a scope with two additional variables implicitly defined: ' index' and ' value', holding the details of that entry. KeyExpr is an arbitrary expression that defines how the items should be ordered. The reference must not be enclosed in parentheses, as that would look like a call to a function named sort() - which is still perfectly valid, "sort" has not become a reserved word. "sort" is only useful in cases where your data exists entirely in the values of the map the keys can have no meaning beyond simply being distinct. To sort on a map, you would want to use a multidimensional maps, but note that you can only sort along a single dimension at a time when doing this. But please note that when you sort a map, you change the values that correspond to the index. For example:Īggregate is a reference to the object to be sorted - arrays are probably the most useful things to sort, but any mapping type can be used. ![]() The "remove" operator removes the "key" from the "slice". Which is just what you expect, if you fully specify the indices for a single dimensional map, "map" -> "map" is the slice and 10 is the key. You can remove a key-value association from a map using the "remove" unary operator:įor clarification, an aggregate reference is "" where specifies the "slice" and specifies the "key". Note that only the current slice's keys are evaluated. (Note that that is enforced at parse time ASH can tell the datatype any expression will produce). ![]() Where must evaluate at run time to a map or slice, and must evaluate at run time to a key of the appropriate type. You can test the presence of a key in a map using the "contains" operator: The syntax for declaring the data type of a map:īoolean animal = props You can pass around entire maps, individual elements, or intermediate maps: "slices". You can fetch data from a map any time you can provide a data value: in an expression, as a function parameter, on the right side of an assignment statement, from a "return" statement, as so on. You can declare a map any time you can declare a variable: as a top level (global) variable, as a function parameter, or as a local variable in any scope. In fact, that's how the syntax we provide for multi-dimensional maps actually operate: maps of maps of maps. This effectively allows multi-dimensional maps and. The value can be any ASH data type at all: a simple type, a record, or can be another map. The key can be any ASH simple data type: boolean, int, float, string, item, location, class, stat, skill, effect, familiar, slot, or monster. Most of this information was copied directly from ASH Maps Tutorial, by Veracity ( )Ī map is indexed by one data type (the key) and associates that key with another (or the same) data type (the value). If you are new to programming or find the information below confusing, you may want to read A Noob's Guide to Maps first. KoLmafia supports complex data structures such as maps and records made from simple data types. 2.1 Differences between arrays and maps. ![]()
