What: Gaming Generators in Tcl Description: A program for generating text description and sound-alike wordlists given syntactical or examplary input. A useful technique for [Procedural Generation|http://en.wikipedia.org/wiki/Procedural_generation] to store a lot of content in little space. See also [Procedural Generation Wiki|http://pcg.wikidot.com/]. Many people are familiar with [MadLibs|http://en.wikipedia.org/wiki/Mad_Libs] which generate funny stories given set syntactical elements such as "insulting adjective" or "odd activity". These are actually a subset of much more powerful Generators or the type that are useful in Gaming -- both [pencil and paper|http://www.seventhsanctum.com/] and in computers with [Procedural Generation Wiki|http://pcg.wikidot.com/]. Tcl is ideally suited to this as it is essentially a macro language designed for text substitution. Unfortunately, Tcl has built-in [recursion limits|interp recursionlimit] which you need to adjust or use a [Non-Recursive Interpreter Engine|NRE] to circumvent. Because of this, I actually implemented a [little language] to do the job with a non-recursive engine in Tcl. I also combined this with the Markov Chains from [Create words from a text file (list)] to generate sound-alike words for names and the like. The resulting system is very useful. Essentially, you define a series of tables, where each table has a list of potential replacements chosen at random, each of which may include references to the same or another table. table first second third result { {Use the table.>} } This is two tables, the second of which has only one choice (hence the double brackets -- anything with embedded spaces will need brackets). Evaluating: might give you: "Use the third table." Another evaluation might give the same, or one of the alternatives. This in itself is not so interesting, the fun part comes in when you start combining productions and nesting tables very deeply. Here is an insult generator written using this same system: insultadj { aberrant abhorrent abject abnormal abominable abrupt absurd abusive acerebral addled addlepated afflictive agelastic aggressive

With a large vocabulary and several different productions available, it actually generates quite a wide selection of insults. To use this thing you need generate.tcl (listed below), the above specification (in Insult.txt) and a program that will produce and use the output. source generate.tcl initgen demo desc "Insult.txt" This creates generator "demo" from "Insult.txt" -- a desc"ription" generator. To get an insult, you evaluate: demo gen Notice the object-orientedness here. Once initialized, the generator becomes self-contained and accessed by name using a normal ensemble command. You can ask for any production by naming the table in <...> to evaluate it. In the event that you would like to be able to repeat a sequence (to reconstruct a description, say) you can use a "tape". demo record demo gen set history [demo gettape] demo loadtape $history demo reset demo playback demo gen ...''should'' produce the same result as the first run. At least, if there are no bugs. The insult generator does this to avoid using the same comment in one run. There are two types of table, the normal, inexhaustable table that may return anything, or an exhaustable table that will not repeat itself until it runs out of options and resets. You specify which a table is using the "-x" switch as the first table entry. You can tune the probability of a given result in a table by repeating it. If you have two entries and you want one of them to be chosen 90% of the time: table { @9<{choose me}> {or choose me} } Is equivalent to: table { {choose me} {choose me} {choose me} {choose me} {choose me} {choose me} {choose me} {choose me} {choose me} {or choose me} } So you get {choose me} nine times - on average - for every time you get {or choose me}. If your generator uses another generator, you can include it with "uses": uses RacialEpithet.txt You can use the generator with the production: and it will (presumably) insert some politically incorrect insult from the specified generator). The word generator swiped wholesale from [Create words from a text file (list)] takes in input list of words that sound similar to the kind of word you want. For example: Elfish-f.txt Aelrue Aelynthi Aerilaya Ahrendue Ahskahala Alaglossa Alais Alavara Alea Alerathla Allannia Allisa Alloralla Allynna Almithara Alvaerele Alyndra Amara Amaranthae Amkissra Amlaruil Amnestria Amra Anarzee Aneirin Anhaern Ara Araushnee Aravae Arcaena Arielimnda Arlayna Arnarra Artin Auluua Aurae Ava Axilya Azariah Blythswana Bonnalurie Braerindra Caerthynna Calarel Chaenath Chalsarda Chandrelle Chasianna Chomylla Cilivren Ciyradyl Claire Daratrine Darshee Dasyra Dathlue Delimbiyra Delshandra Deularla Duilya Eallyrl Ecaeris Edraele Elanalue Elanil Elasha Elenaril Eletha Ellarian Eloen Elora Eshenesra Essaerae Esta Esyae Faunalyn Fhaertala Fieryat Filaurel Filauria Fildaerae Gaelira Gaerradh Gaylia Gemstarzah Ghilanna Glynnii Gweyr Gwynnestri Gylledha Hacathra Halaema Halanaestra Hamalitia Haramara Helartha Holone Huquethae Hycis Ialantha Ikeshia Ildilyntra Ilmadia Ilsevel Ilyrana Ilythyrra Imizael Immianthe Imra Imryll Ioelena Irhaal Isilfarrel Itiireae Itylra Jastra Jeardra Jhanandra Jhaumrithe Jhiilsraa Kavrala Kaylessa Keerla Keishara Kethryllia Keya Kythaela Laamtora Laerdya Lazziar Leilatha Liluth Llamryl Lorelei Maelyrra Maeralya Makaela Malruthiia Mariona Martainn Meira Melarue Merethyl Merialeth Meriel Merlara Mladris Mnuvae Morgwais Moryggan Muerlara Mylaela Mylaerla Myriani Naevys Nakiasha Nambra Nanthleene Naumys Nlaea Nuala Nueleth Nuovis Nushala Nylaathria Ochyllyss Phaerl Phelorna Phuingara Phyrra Quamara Raejiisa Raerauntha Rathiain Renestrae Rubrae Ryllae Saélihn Saelihn Saida Sakaala Sariandi Sarya Seirye Seldanna Selussa Shadowmoon Shalana Shalendra Shalheira Shandalar Shanyrria Sharaera Sheedra Sheera Shialaevar Shyael Sinnafain Soliania Soora Sorsasta Susklahava Sylmae Symrustar Syndra Syviis Taenya Talanashta Talila Talindra Tarasynora Teharissa Teryani Thaola Thasitalia Tiatha Tiriara Tisharu Tsarra Ulelesse Urmicca Uschymna Valindra Vashti Velatha Verrona Vestele Viansola Yaereene Yalanilue Yathlanae Ygrainne Ynshael Yrlissa Yrneha Yrthraethra Ysmyrlda Yulmanda Zoastria Using: initgen demo word "Elfish-f.txt" You get a generator where calls of: demo gen Can produce results like: Allorala Makaelyrra Ghilaya Arnarrel Elanna Filatha Amarantha Leila Nylaathrian Hacathlue However, the system can be more sophisticated than this. A production <...> can include a number of different operations. For example: Will evaluate

and save the result in "save". Further evaluations of will always return the saved result in "save". You can have any number of stored variables from a table. will do the same thing, thereafter will give you the first result and the second. This is useful to save state from productions in process to alter productions yet in the cue. In my spell ingredients table, there is which will save the name of critter which is called for first. Later on, I call: <-bits> where I have a series of tables fish-bits, mammal-bits, bat-bits and so on, so the system will never call for the wing of a fish or a scale of a cow. You can access Tcl functions using "!". > will return "a bat" or "an eland" according to the first letter of the critter. Any Tcl function can be accessed this way. Some other built-ins include, "nth" which will give you "First, Second, Third..." or "1st, 2nd, 3rd..." followed by "Level" or "Circle" to give you a rank. will give you a random number in the specified range. > would give you "Cow" or "Eland" instead of "cow" or "eland". You can check strings for equality or inequality -- notice that since this ''is'' a text substitution engine, you need extra levels of <> to evaluate variables -- for example: <=cow:moo> Will give you "moo" if evaluates to "cow". You can do else clauses too: <=cow:moo/baa> You will get "baa" if is NOT cow. You can invert this operator: <#cow:baa/moo> And, since I swapped the then for the else, you will ''still'' get "baa" if is NOT cow. There is a shorthand for accessing variables. You can check the save variable directly using a prefixed "@": <<@save=cow:moo> ...assumes "save" is already set and bypasses the table entirely. As mentioned earlier, you can access another generator you have added with "uses" Racialepithet.txt: race Elf Human Dwarf Elf-epithet tiny points Spock Human-epithet dummy round-ear Dwarf-epithet shorty grumpy soemthingelse.txt uses RacialEpithet.txt racechoice { { You're a , } } You're an Elf, Spock!
