Platform Team/Sugar Lint

Summary

A set of configuration files and scripts to lint various sugar related code.

During execution, sugar-lint will lint:

• python files by pylint (should be installed before) with custom configuration file and pep8.py (comes with sugar-lint sources),
• vala files by vala-indent (should be installed from http://git.sugarlabs.org/projects/vala-indent).
• C/C++ files by indent command (should be installed)

Install

Clone sugar-lint repository:

git clone git://git.sugarlabs.org/sdk/sugar-lint.git <install-path>
cd <install-path>
git submodule update --init

Add sugar-lint command to PATH e.g. to ~/.bashrc (you need to relogin):

echo PATH=<full-install-path>:$PATH >> ~/.bashrc

Usage

Direct invocation

To lint files:

sugar-lint <file>

To lint all files recursively:

sugar-lint -r .

If fails were detected, call diff command (by default vimdiff or DIFFER environment variable value) to diff the source file and temporary file with comments in problematic places:

sugar-lint -d <file>

Lint files before commiting

To add pre-commit git hook to lint files before commiting to arbitrary project:

ln -s <full-install-path>/sugar_lint/git-pre-commit-hook <project-root>/.git/hooks/pre-commit

Additional syntax in source files

Various sugar-lint related hints that could be used in source files.

Disable sugar-lint

To disable checks entirely for source file.

Python syntax:

# sugar-lint: disable

Vala syntax:

// sugar-lint: disable
/* sugar-lint: disable */

Ignore pep8.py checks in Python sources

# pep8: ignore=code[,code]

Customize lint configuration

After cloning sugar-lint sources it contain default configuration files and configuration might be tuned to local need at any time. Configuration files are:

• sugar_lint/pylintrc
  pylint config file;
• sugar_lint/pep8rc
  pep8.py config file;
• sugar_lint/indent.pro
  indent and vala-indent config file.
