A convenience utility for software source code validation and linting
Project description
VVV is a tool for easy validation and linting integration for your software project containing multiple kinds of files. It integrates with version control and prevents committing files containing bad formatting or syntax errors.
An example use case would be a web project containing HTML, CSS, Javascript and backend programming language files: with VVV you can check with a single command all files conform the policy you set.
Usage
Example output from validating the demo repository where we find errors in a Python and a CSS file. You enter the folder and run vvv against the current folder (.)
$ vvv .
Running vvv against .
/Users/moo/code/vvv/demo/demo.py validation output:
************* Module demo
E0602: 1,9: Undefined variable 'get_magic'
W3C CSS Validator results for file:/Users/moo/code/vvv/demo/foobar.css
Line : 2 .foo
Property backgrnd doesn't exist :
yellow
Installation
VVV is writte in in Python programming language and is compatible with Python interpreter 2.7 or later, including 3.x series.
Benefits
Enforce coding conventions across multiple developers
Enable linting and validators support for your software project with a single command
Automatically guide committers to policy guidelines and let them fix errors themselves, instead of having post-commit personal coaching.
Provide sane default validation and linting options for all popular programming languages and file formats
Run VVV as continuous integration service with systems like Travis CI or Jenkins and shoot down bad code push-ins
What VVV doesn’t do
This is not automated testing tool. We just scan files against a policy, not for programming errors. Linting tools tend to pick up programming errors, too though, like mistyped names.
Features
Set-up for your software repository with two files validation-options.yaml (configuration) and validation-files.yaml (whitelist/blacklist)
VVV automatically downloads and locally installs required software - you don’t need to spend time hunting downloads or distribution packages
Check file against hard tabs and whitespace policies - no more different tab width ever
Prevent committing hard source code breakpoints, like Python’s import pdb ; pdb.set_trace()
Support (on its way) for Subversion, Git, Github, Travis CI, Jenkings and other popular version control and continuous integration systems
Documentation and code
