More Complex Substitution
More complex code in MPI may become difficult to read. Some examples: This sequence informs the user of the next database save:
Next scheduled save will occur at {convsecs:{add:{prop:_sys/dumpinterval,#0}, {prop:_sys/lastdumptime,#0}}}\, being in {ltimestr:{subt:{add: {prop:_sys/dumpinterval,#0},{prop:_sys/lastdumptime,#0}},{secs}}}Next, a loop of a fixed range of iterations that generates random text. A property named ascii on the same object would need to be loaded with the ASCII characters from the 32-127:
{null:{store:,launchcode,this},{if:{&arg},{store:{min:60,{max:1,{&arg}}},count,this}, {store:{dice:60},count,this}},{while:{not:{eq:-1,{store:{subt:{prop:count,this},1},count,this}}}, {store:{prop:launchcode,this}{midstr:{prop:ascii,this},{store:{dice:94},tempcharval,this}, {prop:tempcharval,this}},launchcode,this}}}Combining MPI with the MUCK properties system can allow for a loop with an indefinite number of iterations. One might place this inside a property named delayloop and then {eval} it:
{delay:{prop:seconds,this},{lit:Hello World{null:{if:{awake:me},{eval:{prop:delayloop,this}}}}}}Read more about this topic: Message Parsing Interpreter
Famous quotes containing the words complex and/or substitution:
“All of life and human relations have become so incomprehensibly complex that, when you think about it, it becomes terrifying and your heart stands still.”
—Anton Pavlovich Chekhov (1860–1904)
“To play is nothing but the imitative substitution of a pleasurable, superfluous and voluntary action for a serious, necessary, imperative and difficult one. At the cradle of play as well as of artistic activity there stood leisure, tedium entailed by increased spiritual mobility, a horror vacui, the need of letting forms no longer imprisoned move freely, of filling empty time with sequences of notes, empty space with sequences of form.”
—Max J. Friedländer (1867–1958)
