Pronto

Code Climate Build Status Gem Version Dependency Status Inline docs

Pronto runs analysis quickly by checking only the relevant changes. Created to be used on GitHub pull requests, but also works locally and integrates with GitLab and Bitbucket. Perfect if want to find out quickly if branch introduces changes that conform to your styleguide, are DRY, don't introduce security holes and more.

Pronto demo

Installation

Pronto's installation is standard for a Ruby gem:

$ gem install pronto

You'll also want to install some runners to go along with the main gem:

$ gem install pronto-rubocop
$ gem install pronto-flay

If you'd rather install Pronto using bundler, you don't need to require it, unless you're gonna run it from Ruby (via Rake task, for example):

gem 'pronto'
gem 'pronto-rubocop', require: false
gem 'pronto-flay', require: false

Usage

Pronto runs the checks on a diff between the current HEAD and the provided commit-ish (default is master).

Local Changes

Navigate to the repository you want to run Pronto on, and:

git checkout feature/branch

# Analyze diff of committed changes on current branch and master:
pronto run

# Analyze diff of uncommitted changes and master:
pronto run --index

# Analyze *all* changes since the *initial* commit (may take some time):
pronto run --commit=$(git log --pretty=format:%H | tail -1)

Just run pronto without any arguments to see what Pronto is capable of.

Available Options

Command flag Description
--exit-code Exits with non-zero code if there were any warnings/errors.
-c/--commit Commit for the diff.
-i/--index Analyze changes in git index (staging area).
-r/--runner Run only the passed runners.
-f/--formatters Pick output formatters.

GitHub Integration

You can run Pronto as a step of your CI builds and get the results as comments on GitHub commits using GithubFormatter or GithubPullRequestFormatter.

Add Pronto runners you want to use to your Gemfile:

Set the PRONTO_GITHUB_ACCESS_TOKEN environment variable or value in .pronto.yml to OAuth token that has access to the repository.

Then just run it:

$ PRONTO_GITHUB_ACCESS_TOKEN=token pronto run -f github -c origin/master

or, if you want comments to appear on pull request diff, instead of commit:

$ PRONTO_GITHUB_ACCESS_TOKEN=token pronto run -f github_pr -c origin/master

Use GithubStatusFormatter to submit commit status:

$ PRONTO_GITHUB_ACCESS_TOKEN=token pronto run -f github_status -c origin/master

It's possible to combine multiple formatters. To get both pull request comments and commit status summary use:

$ PRONTO_GITHUB_ACCESS_TOKEN=token PULL_REQUEST_ID=id pronto run -f github_status github_pr -c origin/master

As an alternative, you can also set up a rake task:

Pronto::GemNames.new.to_a.each { |gem_name| require "pronto/#{gem_name}" }

formatter = Pronto::Formatter::GithubFormatter.new # or GithubPullRequestFormatter
status_formatter = Pronto::Formatter::GithubStatusFormatter.new
formatters = [formatter, status_formatter]
Pronto.run('origin/master', '.', formatters)

GitLab Integration

You can run Pronto as a step of your CI builds and get the results as comments on GitLab commits using GitlabFormatter.

note: this requires at least GitLab v7.5.0

Set the PRONTO_GITLAB_API_ENDPOINT environment variable or value in .pronto.yml to your API endpoint URL. If you are using Gitlab.com's hosted service your endpoint will be set by default. Set the PRONTO_GITLAB_API_PRIVATE_TOKEN environment variable or value in `.pronto.yml to your Gitlab private token which you can find in your account settings.

Then just run it:

$ PRONTO_GITLAB_API_PRIVATE_TOKEN=token pronto run -f gitlab -c origin/master

Bitbucket Integration

You can run Pronto as a step of your CI builds and get the results as comments on Bitbucket commits using BitbucketFormatter or BitbucketPullRequestFormatter.

Add Pronto runners you want to use to your Gemfile:

Set the PRONTO_BITBUCKET_USERNAME and PRONTO_BITBUCKET_PASSWORD environment variables or values in .pronto.yml. .

Then just run it:

$ PRONTO_BITBUCKET_USERNAME=user PRONTO_BITBUCKET_PASSWORD=pass pronto run -f bitbucket -c origin/master

or, if you want comments to appear on pull request diff, instead of commit:

$ PRONTO_BITBUCKET_USERNAME=user PRONTO_BITBUCKET_PASSWORD=pass pronto run -f bitbucket_pr -c origin/master

Configuration

The behavior of Pronto can be controlled via the .pronto.yml configuration file. It must be placed in your project directory.

The file has the following format:

all:
  exclude:
    - 'spec/**/*'
# exclude files for single runner
eslint:
  exclude:
    - 'app/assets/**/*'
github:
  slug: mmozuras/pronto
  access_token: B26354
  api_endpoint: https://api.github.com/
  web_endpoint: https://github.com/
gitlab:
  slug: 1234567 # gitlab's project ID
  api_private_token: 46751
  api_endpoint: https://api.vinted.com/gitlab
bitbucket:
  slug: mmozuras/pronto
  username: user
  password: pass
  web_endpoint: https://bitbucket.org/
max_warnings: 150
verbose: false

All properties that can be specified via .pronto.yml, can also be specified via environment variables. Their names will be the upcased path to the property. For example: PRONTO_GITHUB_SLUG or PRONTO_GITLAB_API_PRIVATE_TOKEN. Environment variables will always take precedence over values in configuration file.

Runners

Pronto can run various tools and libraries, as long as there's a runner for it. Currently available:
