A script to remove comments from code.

Project Description


$ pip install XComment


Use the project’s CLI to interact with the script.

Processing files

Say, you are working with the file ./tests/sources/HTML/index.html.

Precondition: virtualenv is activated (of course).

To remove comments (output code without comments to output file) invoke

`shell $ comments_remover ./tests/sources/HTML/input.html HTML ./ ` This will take ./tests/sources/HTML/input.html, designated as HTML file, and put the copy of the former (with HTML-specific comments removed, obviously) to ./ named rc.input.html. The latter is the name of the original file prefixed with rc. by default.

To highlight comments (outputs comments only to output file) invoke

$ comments_remover ./tests/sources/HTML/input.html HTML -p ./

Processing directories

If on start been specified directory path, script will be processing directory recursively with all subdirs for sources by specified language.


For processing archived sources use option -a


$ # remove comments
$ comments_remover ./tmp/ -a Python

$ # highlight comments
$ comments_remover ./tmp/ -a -p Python


-l option enable logging (in stdout by default)

-f < path > specify path to log file


$ comments_remover ./tmp/ -l -f ./remove.log Python

Get supported language list

For get list supported languages use -i option. Result list will returned in json format

$ comments_remover -i

["PHP", "Python", "CSS", "HTML", "JavaScript", "ActionScript", "Ruby",
"Assembly", "AppleScript", "Bash", "CSharp", "VB", "XML", "SQL", "C"]

To see full CLI specification, run

$ comments_remover


Getting Up-and-Running Locally

Tested with the following configuration:

  • Ubuntu 16.04 / 17
  • Python 3.6.

Note: the below occurences of `./` refer to the project root unless explicitly stated otherwise.

Setting Things Up on Ubuntu

  1. Enter the shell.

  2. Install pyenv via [pyenv-installer](

    $ curl -L | bash
  3. Follow the instructions on how to initialize pyenv on shell startup, for instance:

    $ echo 'export PATH="/root/.pyenv/bin:$PATH"' >> ~/.bash_profile
    $ echo 'eval "$(pyenv init -)"' >> ~/.bash_profile
    $ echo 'eval "$(pyenv virtualenv-init -)"' >> ~/.bash_profile
  4. Install Python 3.6.x via pyenv, say Python 3.6.2 (latest micro release versions are preferred):

    $ pyenv install 3.6.2
  5. Create a virtualenv for the project:

    $ pyenv virtualenv 3.6.2 comments_remover
  6. Switch to whatever directory you wish the project to reside in, say ~:

    $ cd ~
  7. Clone the project from GitHub:
    • either via SSH (the preferred way):
    $ git clone
    • or via HTTPS:
    $ git clone
  8. Switch to the project directory:

    $ cd comments_remover
  9. Activate the virtualenv:

    $ pyenv activate comments_remover
  10. Install project dependencies:

    $ pip install -U -r ./requirements.txt
  11. Install dependencies for testing:

    $ pip install -U -r ./requirements-test.txt
  12. (optional) Install [IPython]( interactive shell to speed up development:

    $ pip install ipython==6.1.0

To run tests, simply

$ pytest ./

To also see coverage report,

pytest --cov ./

You should be good to go now.


Pip registry

Install dependencies

$ python install -r requirements-deploy.txt

Set pypi credentials

$ export TWINE_USERNAME=<pypi username>
$ export TWINE_PASSWORD=<pypi password>

Create distribution

$ python sdist bdist_wheel


$ twine upload dist/XComment-x.y.z.tar.gz


If you’re not using [PyCharm]( yet, make sure to at least consider this as an option. Also check out [JetBrains Toolbox](, a single tool to rule them all (the JetBrains products). To stay up-to-date, follow [PyCharm Blog](
