Pylint JSON report to HTML

Project description

# pylint-json2html

A pylint JSON report file to HTML: pylint is used to generate a JSON report,
and this tool will transform this report into an HTML document:

usage: pylint-json2html [-h] [-o FILENAME] [-f FORMAT] [FILENAME]

Transform Pylint JSON report to HTML

positional arguments:
FILENAME Pylint JSON report input file (or stdin)

optional arguments:
-h, --help show this help message and exit
Pylint HTML report output file (or stdout)
-f FORMAT, --input-format FORMAT
Pylint JSON Report input type (json or jsonextended)

## Why?

Since its [1.7 version](,
Pylint does not provide an HTML output format. The release notes say that:

> It was lately a second class citizen in Pylint, being mostly neglected.
> Since we now have the JSON reporter, it can be used as a basis for building
> more prettier HTML reports than what Pylint can currently generate.
> This is part of the effort of removing cruft from Pylint, by removing less
> used features.

And I agree with that statements. Few people use the HTML reports, and pylint
is getting old. Its core features are complex and they require a lot of times
and efforts - and I am thankful for that software to exist in the first place!

So here it is: a plugin to fulfill my own needs. I share it as open-source
because why not?

## Installation

To install this tool, use pip:

(venv) $ pip install pylint-json2html

You can always download the sources from the github repository, and use the
`` file to `install` or `develop`, but I would not recommend that
unless you plan to contribute to this small project of mine.

## Usage

My favorite way of using `pylint` and `pylint-json2html` is this one:

(venv) $ pylint my_package | pylint-json2html -o pylint.html

Provided that you configure your Pylint config file with:


But you can generate first a JSON file, then use `pylint-json2html` to read it:

(venv) $ pylint your_package > pylint.json
(venv) $ pylint-json2html -o pylint.html pylint.json

You can also redirect `pylint-json2html`'s stdout:

(venv) $ pylint-json2html pylint.json > pylint.html

## Extended Report

Actually, I lied about my favorite way, it is this one:

(venv) $ pylint my_package | pylint-json2html -f jsonextended -o pylint.html

With this Pylint configuration:



The `pylint_json2html` is a Pylint plugin that adds a new output format:
`jsonextended`. By default, the `json` format contains only a list of messages,
and this new format contains also metrics, such the number of analysed
statements, or the list of dependencies.

The configuration above can be tested using the command line instead:

(venv) $ pylint --load-plugins=pylint_json2html --output-format=jsonextended your_package > pylint.json

Then, you will be able to use the JSON extended report to generate an HTML

(venv) $ pylint-json2html -f jsonextended -o pylint.html > pylint.json

And voilà!
