Geordi

Geordi is a collection of command line tools we use in our daily work with Ruby, Rails and Linux at makandra.

Installation:

gem install geordi

geordi

The geordi binary holds most of the utility commands. For the few other binaries, see the bottom of this file.

You may abbreviate commands by typing only their first letters, e.g. geordi con will boot a development console, geordi set -t will setup a project and run tests afterwards.

Commands will occasionally print "did you know" hints of other Geordi features.

You can always run geordi help <command> to quickly look up command help.

geordi branch

Check out a feature branch based on a story from Pivotal Tracker.

Example: geordi branch

On the first execution we ask for your Pivotal Tracker API token and for your Git user initials. Both will be stored in ~/.config/geordi/global.yml.

Options

• -m, [--from-master], [--no-from-master]: Branch from master instead of the current branch

geordi capistrano COMMAND

Run a Capistrano command on all deploy targets.

Example: geordi capistrano deploy

geordi chromedriver-update

Update the chromedriver.

Example: geordi chromedriver_update

This command will find and install the matching chromedriver for the currently installed Chrome.

Setting auto_update_chromedriver to true in your global Geordi config file (~/.config/geordi/global.yml), will automatically update chromedriver before cucumber tests if a newer chromedriver version is available.

geordi clean

Remove unneeded files from the current directory.

geordi commit

Commit using a story title from Pivotal Tracker.

Example: geordi commit

Any extra arguments are forwarded to git commit -m <message>.

On the first execution we ask for your Pivotal Tracker API token. It will be stored in ~/.config/geordi/global.yml.

geordi console [TARGET]

Open a Rails console locally or on a Capistrano deploy target.

Local (development): geordi console

Remote: geordi console staging

Selecting the server: geordi console staging -s shows a menu with all available servers. When passed a number, directly connects to the selected server.

IRB flags can be given as irb_flags: '...' in the global Geordi config file (~/.config/geordi/global.yml).

Options

• -s, [--select-server=[SERVER_NUMBER]]: Select a server to connect to

geordi cucumber [FILES and OPTIONS]

Run Cucumber features.

Example: geordi cucumber features/authentication_feature:3

Runs Cucumber with bundle exec, using parallel tests and with support for re-running failed scenarios.

Any unknown option will be passed through to Cucumber, e.g. --format=pretty. Make sure to connect option and value with an equals sign, i.e. have each option a contiguous string.

In order to limit processes in a parallel run, you can set an environment variable like this: PARALLEL_TEST_PROCESSORS=6 geordi cucumber

Options

• -m, [--modified], [--no-modified]: Run all modified features
• -c, [--containing=STRING]: Run all features that contain STRING
• -v, [--verbose], [--no-verbose]: Show the test run command
• -d, [--debug], [--no-debug]: Run Cucumber with -f pretty -b, which helps hunting down bugs
• -r, [--rerun=N]: Rerun features up to N times while failing

geordi delete-dumps [DIRECTORY]

Help deleting database dump files (*.dump).

Example: geordi delete-dumps or geordi delete-dumps ~/tmp/dumps

Recursively searches for files ending in .dump and offers to delete them. When no argument is given, two default directories are searched for dump files: the current working directory and ~/dumps (for dumps created with geordi).

Will ask for confirmation before actually deleting files.

geordi deploy [STAGE]

Guided deployment across branches.

Example: geordi deploy or geordi deploy p[roduction] or geordi deploy --current-branch

Merge, push and deploy with a single command! It always tells what it will do before it does it. There are different scenarios where this command is handy:

• Production deploy: From the master branch, run geordi deploy production. This will merge master to production, push and deploy to production.

• Feature branch deploy: From a feature branch, run geordi deploy staging. This will merge the feature branch to master, push and deploy to staging.

  To deploy a feature branch directly without merging, run geordi deploy --current-branch. This feature depends on the environment variable DEPLOY_BRANCH to be picked up in the respective deploy file.

• Simple deploy: If the source branch matches the target branch, merging will be skipped.

Calling the command without arguments will infer the target stage from the current branch and fall back to master/staging.

Finds available Capistrano stages by their prefix, e.g. geordi deploy p will deploy production, geordi deploy mak will deploy a makandra stage if there is a file config/deploy/makandra.rb.

When your project is running Capistrano 3, deployment will use cap deploy instead of cap deploy:migrations. You can force using deploy by passing the -M option: geordi deploy -M staging.

Options

• -M, [--no-migrations], [--no-no-migrations]: Run cap deploy instead of cap deploy:migrations
• -c, [--current-branch], [--no-current-branch]: Set DEPLOY_BRANCH to the current branch during deploy

geordi drop-databases

Interactively delete local databases.

Example: geordi drop_databases

Check both MySQL/MariaDB and Postgres on the machine running geordi for databases and offer to delete them. Excluded are databases that are whitelisted. This comes in handy when you're keeping your currently active projects in the whitelist files and perform regular housekeeping with Geordi.

Per default, Geordi will try to connect to the databases as a local user without password authorization.

Geordi will ask for confirmation before actually dropping databases and will offer to edit the whitelist instead.

Options

• -P, [--postgres-only], [--no-postgres-only]: Only clean PostgreSQL
• -M, [--mysql-only], [--no-mysql-only]: Only clean MySQL/MariaDB
• [--postgres=PORT_OR_SOCKET]: Use PostgreSQL port or socket
• [--mysql=PORT_OR_SOCKET]: Use MySQL/MariaDB port or socket
• -S, [--sudo], [--no-sudo]: Access databases as root

geordi dump [TARGET]

Handle (remote) database dumps.

geordi dump (without arguments) dumps the development database with dumple.

geordi dump -l tmp/staging.dump (with the --load option) sources the specified dump file into the development database.

geordi dump staging (with a Capistrano deploy target) remotely dumps the specified target's database and downloads it to tmp/.

geordi dump staging -l (with a Capistrano deploy target and the --load option) sources the dump into the development database after downloading it.

If you are using multiple databases per environment, Geordi defaults to the "primary" database, or the first entry in database.yml. To target a specific database, pass the database name like this:

geordi dump -d primary

When used with the blank load option ("dump and source"), the database option will be respected both for the remote and the local database. If these should not match, please issue separate commands for dumping (dump -d) and sourcing (dump -l -d).

Options

• -l, [--load=[DUMP_FILE]]: Load a dump
• -d, [--database=NAME]: Target database, if there are multiple databases

geordi help [COMMAND]

Describe available commands or one specific command.

geordi migrate

Migrate all databases.

Example: geordi migrate

If you are using parallel_tests, this runs migrations in your development environment and rake parallel:prepare afterwards. Otherwise, invokes geordi rake with db:migrate.

geordi png-optimize PATH

Optimize .png files.

Example: geordi png-optimize some/directory

• Removes color profiles: cHRM, sRGB, gAMA, ICC, etc.
• Eliminates unused colors and reduces bit-depth (if possible)
• May reduce PNG file size lossless

geordi rake TASK

Run a rake task in several Rails environments.

Example: geordi rake db:migrate

TASK is run in the following Rails environments (if present):

• development
• test
• cucumber

geordi remove-executable-flags

Remove executable-flags from files that should not be executable.

geordi rspec [FILES]

Run RSpec.

Example: geordi rspec spec/models/user_spec.rb:13

Runs RSpec with version 1/2 support, parallel_tests detection and bundle exec.

In order to limit processes in a parallel run, you can set an environment variable like this: PARALLEL_TEST_PROCESSORS=6 geordi rspec

geordi security-update [STEP]

Support for performing security updates.

Preparation for security update: geordi security-update. Checks out production and pulls.

After performing the update: geordi security-update finish. Switches branches, pulls, pushes and deploys as required by our workflow.

This command tells what it will do before it does it. In detail:

1. Ask user if tests are green

2. Push production

3. Check out master and pull

4. Merge production and push in master

5. Deploy staging, if there is a staging environment

6. Ask user if deployment log is okay and staging application is still running

7. Deploy other stages

8. Ask user if deployment log is okay and application is still running on all stages

9. Inform user about the next (manual) steps

geordi server [PORT]

Start a development server.

Options

• -p, [--port=PORT]: Choose a port
• -P, [--public], [--no-public]: Make the server accessible from the local network

geordi setup

Setup a project for the first time.

Example: geordi setup

Check out a repository and cd into its directory. Then let setup do the tiring work: run bundle install, create database.yml, create databases, migrate (all if applicable).

If a local bin/setup file is found, Geordi skips its routine and runs bin/setup instead.

Options

• -d, [--dump=TARGET]: After setup, dump the TARGET db and source it into the development db
• -t, [--test], [--no-test]: After setup, run tests

geordi shell TARGET

Open a shell on a Capistrano deploy target.

Example: geordi shell production

Selecting the server: geordi shell staging -s shows a menu with all available servers. When passed a number, directly connects to the selected server.

Options

• -s, [--select-server=[SERVER_NUMBER]]: Select a server to connect to

geordi tests [FILES]

Run all employed tests.

When running geordi tests without any arguments, all unit tests, rspec specs and cucumber features will be run.

When passing file paths or directories as arguments, Geordi will forward them to rspec and cucumber. All rspec specs and cucumber features matching the given paths will be run.

geordi unit

Run Test::Unit.

Supports parallel_tests, binstubs and bundle exec.

In order to limit processes in a parallel run, you can set an environment variable like this: PARALLEL_TEST_PROCESSORS=6 geordi unit

geordi update

Bring a project up to date.

Example: geordi update

Performs: git pull, bundle install (if necessary) and migrates (if applicable).

Options

• -d, [--dump=TARGET]: After updating, dump the TARGET db and source it into the development db
• -t, [--test], [--no-test]: After updating, run tests

geordi version

Print the current version of geordi.

• --compress: After dumping, run gzip to compress the dump in place

Contributing

When making changes to Geordi, please make sure your code is tested. Not all, but most features of Geordi can be tested. See other tests for inspiration.

Once you have completed your modifications, please update CHANGELOG and README as needed. Use rake readme to regenerate the Geordi section of the README from the command documentations.

Make sure tests are green in the oldest supported Ruby version. Before releasing a new gem version, wait for the CI results to see that tests are green in all Ruby versions.

Adding a new command

Copy lib/geordi/COMMAND_TEMPLATE to lib/geordi/commands/your_command and edit it to do what you need it to do. Please add appropriate tests for the new command; see existing tests for inspiration.

Running Geordi locally

To run Geordi without installation, call it like this:

ruby -I lib exe/geordi

# With debugger
ruby -r byebug -I lib exe/geordi

# From another directory
ruby -I ../geordi/lib ../geordi/exe/geordi

# Run Geordi with the Ruby version of that other directory
RBENV_VERSION=$(<.ruby-version) ruby -I ../geordi/lib ../geordi/exe/geordi

You can also install Geordi locally from its project directory with rake install. Make sure to switch to the expected Ruby version before.
