Lua API
Mudlet defines several global Lua variables that are accessible from anywhere.
| Built-in Lua Variables | |||||
|---|---|---|---|---|---|
| Variable Name | Description | ||||
| comand | This variable holds the current user command. This is typically used in alias scripts. | ||||
| line | This variable holds the content of the current line as being processed by the trigger engine. The engine runs all triggers on each line as it arrives from the MUD. | ||||
| matches[n] | This Lua table is being used by Mudlet in the context of triggers that use Perl regular expressions.
matches[1] holds the entire match, matches[2] holds the first capture group, matches[n] holds the nth-1 capture group. If the trigger uses the Perl style /g switch to evaluate all possible matches of the given regex within the current line, matches[n+1] will hold the second entire match, matches[n+2] the first capture group of the second match and matches[n+m] the m-th capture group of the second match. | ||||
| multimatches[n][m] | This table is being used by Mudlet in the context of multiline triggers that use Perl regular expression. It holds the table matches[n] as described above for each Perl regular expression based condition of the multiline trigger. multimatches[5][4] may hold the 3rd capture group of the 5th regex in the multiline trigger. This way you can examine and process all relevant data within a single script. Have a look at this example. | ||||
