Quick automated code review of your changes
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 you want to find out quickly if a branch introduces changes that conform to your styleguide, are DRY, don't introduce security holes and more.
This README might be ahead of the latest release. Find the README for v0.11.5 here.
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
Pronto runs the checks on a diff between the current HEAD and the provided commit-ish (default is master).
[!NOTE] If the default branch is NOT
master, invokepronto run -c=<branch>OR set thedefault_commitconfig value.
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 changes in git staging area
pronto run --staged
# Analyze diff of uncommitted changes and master:
pronto run --unstaged
# 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.
--staged
Analyze changes in git staging area
--unstaged
Analyze changes made, but not in git staging area
-r/--runner
Run only the passed runners.
-f/--formatters
Pick output formatters.
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
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
If you want review to appear on pull request diff, instead of separate comments:
$ PRONTO_GITHUB_ACCESS_TOKEN=token pronto run -f github_pr_review -c origin/master
All the N pending comments will be now separated into X number of PR reviews. The number of the PR reviews will be controlled by an additional environment variable or with the help of a config setting. This way, by a single pronto run, all the comments will be published to the PR, but divided into small reviews in order to avoid the rate limit of the providers.
X = N / {PRONTO_WARNINGS_PER_REVIEW || warnings_per_review || 30})
Note: In case no environment variable or config setting is specified in .pronto.yml,
a default value of 30 will be used.
$ PRONTO_WARNINGS_PER_REVIEW=30 PRONTO_GITHUB_ACCESS_TOKEN=token pronto run -f github_pr_review -c origin/master
Use GithubStatusFormatter to submit commit status:
$ PRONTO_GITHUB_ACCESS_TOKEN=token pronto run -f github_status -c origin/master
If you want to show a one single status for all runners, instead of status per runner:
$ PRONTO_GITHUB_ACCESS_TOKEN=token pronto run -f github_combined_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 PRONTO_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 # also possible: GithubPullRequestFormatter, GithubPullRequestReviewFormatter
status_formatter = Pronto::Formatter::GithubStatusFormatter.new
formatters = [formatter, status_formatter]
Pronto.run('origin/master', '.', formatters)
You can also run Pronto as a GitHub action.
Here's an example .github/workflows/pronto.yml workflow file using the github_status and github_pr formatters and running on each GitHub PR, with pronto-rubocop as the runner:
…
check Wiki on GitHub Actions Integration for more info.
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
note: this requires at least Gitlab 11.6+
Merge request integration:
$ PRONTO_GITLAB_API_PRIVATE_TOKEN=token PRONTO_PULL_REQUEST_ID=id pronto run -f gitlab_mr -c origin/master
On GitLabCI, make sure to run Pronto in a merge request pipeline:
…
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
The behavior of Pronto can be controlled via the .pronto.yml configuration
file. It can either be placed in the working directory (*) or specified using
the environment variable PRONTO_CONFIG_FILE.
(*) The working directory is where you run the command from, which is typically your project directory.
If this file cannot be found, then the default configuration in Pronto::ConfigFile::EMPTY applies.
The file has the following format:
…
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.
max_warnings
Limits the amount of warnings. Returns all warnings if option is skipped.
runners
Runs only listed runners. Runs everything if option is skipped.
skip_runners
All, except listed runners will be executed. Runs everything if option is skipped.
verbose
Outputs more information when set to true.
warnings_per_review
Limits the amount of warnings per review. Returns all warnings if option is skipped.
default_commit
Commit-ish pronto run will execute runners against.
Pronto allows you to configure the format of the messages that are produced. You can set a default format that will be used by all formatters, or you can configure a separate format per formatter, if you are using several.
To change the default format:
format: "%{runner} %{level} %{msg}"
To add the title of the Runner to the GitHub Pull Request formatter only:
github_pr:
format: "%{runner} - %{msg}"
The available values to be interpolated into the message are:
Key Descriptionpath
File path.
line
Line number.
level
Message level.
msg
Message.
commit_sha
SHA.
runner
Runner name.
The following values are available only to the text formatter:
Key Descriptioncolor_level
Colorized message level.
color_location
Colorized location.
Pronto can run various tools and libraries, as long as there's a runner for it. Currently available:
