Sometimes it is required to implement Enum on your own. E.g. there is no clear way to extend other enums. Custom implementation allows this: class Enum { constructor(protected value: string) {} public toString() { return String(this.value); } public is(value: Enum | string) { ...

enum SourceEnum { value1 = <any>'value1', value2 = <any>'value2' } enum AdditionToSourceEnum { value3 = <any>'value3', value4 = <any>'value4' } // we need this type for TypeScript to resolve the types correctly type TestEnumType = SourceEnum | AdditionToS...

Can be used in conjunction with the custom form example to create a table in the drupal database for a Mailing List feature. This example was made by creating the table directly in my development database, then created the data for hook_schema() using the Schema module. This allows for automatic t...

This is the definition of a TEMP-TABLE named ttTempTable with three fields. NO-UNDO indicates that no undo handling is needed (this is usually what you want to do unless you really need the opposite). DEFINE TEMP-TABLE ttTempTable NO-UNDO FIELD field1 AS INTEGER FIELD field2 AS CHARACTER ...

Temp-tables can (and should) be created with indices if you plan to run queries against them. This table has one index (index1) containing of one field (field1). This index is primary and unique (meaning not two records can have the same contents of field1). DEFINE TEMP-TABLE ttTempTable NO-UNDO ...

@sorted = sort @list; @sorted = sort { $a cmp $b } @list; sub compare { $a cmp $b } @sorted = sort compare @list; The three examples above do exactly the same thing. If you don't supply any comparator function or block, sort assumes you want the list on its right sorted lexically. This is ...
