From Newsgroup: comp.programming

So, right now I'm programming a /plain text formatter/
(e.g., something like RUNOFF).

I already have a paragraph wrapper and a hyphenator
(for English and German), but so far one needed to write
custom code to use them.

Now, I am writing a little input language. I already had
implemented a syntactic framework before that can parse
text into a tree (AST)

So what I actually implemented today was the step from the
input to a representation with codes for line breaks.

For example, my program now accepts this input:

< &paragraphs
< &par
< &segment [This is an example.] >
>
>

and generates this output:

< &paragraphs
< &parlist
"This"
[' ', ['', '']]
"is"
[' ', ['', '']]
"an"
[' ', ['', '']]
"example."
[' ', ['', '']]
>>

. The "[' ', ['', '']]" can be understood by the wrapper as a space
with an option to break the line there.

Disclaimer: The intermediate representation shown as "output"
above is a data structure (a tree) and its debug output by my
program was edited for this post to make it more readable.

Possible continuation of my work: In a next session I might take
the above output and transform it into the exact format my paragraph
wrapper requires as input, so that I then can actually feed my
paragraph to my wrapper. Hyphenation will only be implemented later.
