A Markov Text generator in Nim (v 0.19)

Uses markov chains (https://en.wikipedia.org/wiki/Markov_chain) to generate nonsensical but somewhat grammatically valid text from one or more text files.

To build the command line utility:

nim --define:MarkovCmd c markov.nim

To use as a library just import and don't define "MarkovCmd"

To use the command line utility to generate text: markov <options>

All options have a short "-r" and a long command "--read" and are followed by an argument

Markov Order A Markov Order is the number of phrases considered to be a "state" in the markov chain. The higher this is the more like the original text your output will be.

-o <integer> or --order <integer>

Sentence Count This determines the number of sentences generated by the utility. Default is 500.

-c <integer> or --count <integer>

Load datafile This option loads a previously created sqlite database file into the markov generator.

-l <filename> or --load <filename>

Read Files This option reads files into the markov generator as sample text.

-r <textfile> or --read <textfile>

Save datafile This option (which happens after generating sentences) writes the markov generator to a sqlite datafile.

-s <filename> or --save <filename>

The save option will clear out all data if the datafile exists.

For corpus, project gutenberg is a good source of text. Of course just about any grammatically valid text will do.

Have fun.
