Project's Background Story

Hacking

Clone the repository:

$ git clone https://github.com/rhcarvalho/typokiller.git

Build and runtime requirements:

• Proper Go environment (tested with Go 1.4.1, probably works with older versions)
• Python 2.x (seems to work faster with PyPy)

It's recommended to install PyPy and use it inside a virtualenv.

Activate the virtualenv and run:

$ pip install -r requirements.txt

Build and install Go executable:

$ cd typokiller
$ go get ./...

Usage

The shortcut:

$ ./killtypos PATH ...

This will build and install typokiller, read the documentation of the Go packages in PATH(s), spellcheck it all, and present a terminal-based UI for fixing typos.

Integrate with find for great profit:

$ ./killtypos $(find /PATH/TO/GIT/REPO -type d -not \( -name .git -prune -o -name Godeps -prune \))

This will find typos in all directories under /PATH/TO/GIT/REPO (inclusive), ignoring anything under .git and Godeps.

typokiller also supports an additional format: AsciiDoc. You can use it to fix typos in documentation or generally files in the AsciiDoc format:

$ ./killtypos --format=adoc $(find /PATH/TO/GIT/REPO -type d -not \( -name .git -prune \))

You can also use the parts separately for debugging or integration with other UNIX tools:

# normal usage:
$ typokiller read /PATH/TO/GO/PKG | ./spellcheck.py | typokiller fix

# inspect spellcheck results manually:
$ typokiller read /PATH/TO/GO/PKG | ./spellcheck.py | ./pprint_json.py | less

# limit number of packages:
$ typokiller read /PATH/TO/GO/PKG | head -n 20 | ./spellcheck.py | ./pprint_json.py | less
