T-Rext is a command-line filter that attempts to clean up spaces and punctuation in a text file. Its purpose is so that, when you are writing a text generator, such as a Markov processor, you need not worry too much about its output format; just toss its output through T-Rext when you're done to make it more presentable.


bin/t-rext raw_output.txt > cleaned_output.txt

This will take lines that look like this:

" Well , " said the king , , " no . "

and reformat them to look like this:

“Well,” said the king, “no.”

To use T-Rext from any working directory, add the bin directory in this repository to your PATH. For example, you might add this line to your .bashrc:

export PATH=/path/to/this/repo/bin:$PATH

T-Rext is built on an over-engineered library of pipeline processors, which you can use directly (note, its interface is not stable and liable to change.) To use the T-Rext Python modules in other Python programs, make sure the src directory of this repository is on your PYTHONPATH. For example, you might add this line to your .bashrc:

export PYTHONPATH=/path/to/this/repo/src:$PYTHONPATH

Then you can add imports like this to the top of your script:

from t_rext.processors import TrailingWhitespaceProcessor

An easy way to accomplish the above two things is to dock T-Rext using shelf:

cd ~/checkout && shelf_dockgh catseye/T-Rext


This is a test suite, written in Falderal format, for the t-rext utility. It also serves as documentation for said utility.

-> Functionality "Clean up punctuation and spaces" is implemented by

-> Tests for functionality "Clean up punctuation and spaces"

Spaces before commas and periods are elided.

| Well , that is good .
= Well, that is good.

Multiple commas are collapsed into a single comma.

| Well , , that is good .
