Generate boilerplate from source code comments.

Project description

This is a boilerplate generator that generates code based on the comments it finds in source code.

Motivation

The motivation is that ordinary boilerplate generators either require you to hack the build system you’re using (to build the source code on the fly) or you statically generate the boiler plate (and are then unable to modify it or generate more without pulling together the script that first generated it).

The original use of this was to generate definitions of constants in homework assignments done in the Racket programming language. So as an example of writing a test code for rational number data-type:

;; Constant Gen: r([0-9]+)/([0-9]+) (make-rational \1 \2)

(check-expect (rational-add r7/9 r5/6) r29/18)

Would become:

;; Constant Gen: r([0-9]+)/([0-9]+) (make-rational \1 \2)
(define r29/18 (make-rational 29 18))
(define r5/6 (make-rational 5 6))
(define r7/9 (make-rational 7 9))

(check-expect (rational-add r7/9 r5/6) r29/18)

And no matter how many times you run the program on the source file, it will only generate the same output, or add/remove boilerplate according to how the source file changed.

With this, one can keep the boilerplate in VCS and use txt2boil to update it whenever they need to.

Installation

The preferred way to install this is using pip:

pip install txt2boil

Although if you’re not a regular pip user or are not used to using pip then the alternative is to just download the repository with git:

git clone https://github.com/kcolford/txt2boil.git
cd txt2boil

Or you can download the tar package from the PyPi website by clicking here and then clicking on the big green Download icon. Alternatively you can use wget (or curl if you prefer):

wget https://pypi.python.org/packages/source/t/txt2boil/txt2boil-x.x.x.tar.gz

Once you have the tar ball, unpack it and change to the directory containing it:

tar xf txt2boil-x.x.x.tar.gz
cd txt2boil-x.x.x

Once you’re in the source repository (regardless of how you got it) run the setup.py script:

python setup.py install

How To Use

In order to use txt2boil as in the example above, simply use:

txt2boil -i rational.rkt

The -i option specifies to update the file in place rather than outputting it on stdout.

Supported Languages

Language support all depends on what language the package’s core library has functionality for. The current languages that are supported are:

  • C
  • C++
  • Java
  • Python
  • Racket

Internet Presence

There are two significant web resources for txt2boil. The first is the source repository and the second is the PyPi page. Regardless of which one you go to, this document ought to be the main page found there.

The primary source repository can be found at Git Hub while the PyPi (Python Package Index) page can be found here.

While the Git Hub repository only has source code, the PyPi page has downloads for binary distributions. These binary distributions are provided by anyone generous enough to lend their computer to the task of compiling them and uploading them. Anyone who has privileges to upload to PyPi need only run either the shell script upload.sh or the batch script upload.bat.
