After so many “
Test drive:” blog post I sometimes feel that my writing has become too much repetitive. I so decided to have some relax and, with a little of self-irony, I'll try writing a random blog post generator using
Polygen. Writing a full post generator is a huge task: as you start decomposing a phrase structure the number of options literally explode. So let's start just with generating the post title.
A top down approach
The top-down approach is the one I find more natural while dealing with a Polygen grammar, so let's start with defining the very basic structure of a blog post
S ::= Title "\n"^
Body "\n"^
Tags;
the “\n” string is a new line escape character while the “^” operator tells Polygen to concatenate without adding spaces (To avoid a new line starting with a space).
We'll set the “Body” symbol to an empty preposition and forget about if (at least for the moment).
Body ::= _;
Titles for “review style” posts are usually something like “installed some-program on some-system”; this can be written, in Polygen grammar language, like following:
Title ::= Action (Program ("on the" Computer | "on" Os | "on the" Computer "and" Os) | Os "on the" Computer);
