Triggers

/action {<pattern>} {<commands>}   (or /ac, /trigger, /tr)
/action                            lists your triggers
/unaction {<pattern>}              removes one
/t- {<pattern>} or /t+ {<pattern>} turns one off or on
/ignore                            turns all triggers off, or on

A trigger watches the game's text: when a line has the pattern in it, its commands run, as if you had typed them.

/ac {the grate is closed} {open grate}

Patterns ignore case, and can hold these:

• any text %d a number %w a word {a|b|c} any one of these ^ first the line must start with the pattern $ last the line must end with it ~ the next character as itself (~* is a star)

What the wildcards matched is %1, %2... in the commands. Put ( ) around the parts to keep when not all of them matter:

/ac {%w gives you *} {say Thanks, %1!}
/ac {You get (%d) gold coins from *} {/add gold %1}

If triggers fire more than 20 times in two seconds (a trigger setting off itself), they all turn off; /ignore turns them on again.
