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
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.
For details on commands, e.g. supported options, you may always run
geordi help <command>
.
Enable the given virtual host, disabling all others.
Run a capistrano command on all deploy targets.
Example: geordi capistrano deploy
Remove unneeded files from the current directory.
Commit using a story title from Pivotal Tracker.
Open a Rails console locally or on a Capistrano deploy target.
Open a local Rails console: geordi console
Open a Rails console on staging
: geordi console staging
Run Cucumber features.
Example: geordi cucumber features/authentication_feature:3
Runs Cucumber as you want: with bundle exec
, using parallel tests, with
a VNC session holding Selenium test browsers, support for using a dedicated
testing firefox and beta support for rerunning failed scenarios.
-
@solo: Generally, features are run in parallel. However, scenarios tagged with @solo are excluded and will be run sequentially, after the parallel run.
-
Debugging: Sometimes, the dot-printing Cucumber formatter does not show errors. In case a feature fails without a message, try running it with
--debug
or-d
. -
Options: Any unknown option will be passed through to Cucumber, but you need to use an
=
instead of a space to separate parameter name and value, e.g.--format=pretty
.
Guided deployment across branches.
Example: geordi deploy
or geordi deploy p[roduction]
Merge, push and deploy with a single command! There are several scenarios where this command comes in handy:
-
Production deploy: From the master branch, run
geordi deploy production
. This will mergemaster
toproduction
, push and deploy to production. -
Feature branch deploy: From a feature branch, run
geordi deploy staging
. This will merge the feature branch tomaster
, push and deploy to staging. -
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
.
Handle dumps (see geordi help dump
for details).
When called without arguments, dumps the development database with dumple
.
geordi dump
When called with the --load
option, sources the specified dump into the
development database.
geordi dump -l tmp/staging.dump
When called with a capistrano deploy target (e.g. staging
), remotely dumps
the specified target's database and downloads it to tmp/
.
geordi dump staging
When called with a capistrano deploy target and the --load
option, sources the
dump into the development database after downloading it.
geordi dump staging -l
Run a command with VNC and test browser set up (alias: chrome).
Example: geordi firefox b cucumber
or geordi firefox --setup 24.0
Useful when you need Firefox for Selenium or the VNC set up, but can't use the
geordi cucumber
command.
Install a special Firefox by calling with --setup <version>
.
This command is aliased chrome
for users running Selenium in Chrome.
Describe available commands or one specific command.
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
.
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
[sudo] Purge linux kernels older than the current one.
Example: sudo geordi purge-kernels
/boot quickly gets cluttered with unused old kernels, finally rendering your machine unable to install updates.
This script will retrieve and print a list of all current or older kernels. If confirmed, it will then purge all kernels older than the current one.
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
Remove executable-flags from files that should not be executable.
Run RSpec.
Example: geordi rspec spec/models/user_spec.rb:13
Runs RSpec as you want: with RSpec 1/2 detection, bundle exec
, rspec_spinner
detection, etc.
Support for performing security updates.
Preparation for security update: geordi security-update
After performing the update: geordi security-update finish
Switches branches, pulls, pushes and deploys as required by our workflow. Tells what it will do before it does it.
Start a development server.
Setup a project for the first time.
Example: geordi setup
Check out a repository, cd into its directory. Now let setup
do the tiring
work: run bundle install
, create database.yml
, create databases, migrate
(all if applicable).
After setting up, loads a dump into the development db when called with the
--dump
option:
geordi setup -d staging
After setting up, runs all tests when called with the --test
option:
geordi setup -t
See geordi help setup
for details.
Open a shell on a Capistrano deploy target.
Example: geordi shell production
Lets you select the server to connect to when called with --select-server
:
geordi shell production -s
Run all employed tests.
Run Test::Unit.
Bring a project up to date.
Example: geordi update
Performs: git pull
, bundle install
(if necessary) and migrates (if applicable).
After updating, loads a dump into the development db when called with the
--dump
option:
geordi update -d staging
After updating, runs all tests when called with the --test
option:
geordi update -t
See geordi help update
for details.
Print the current version of geordi.
Show the hidden VNC window.
Example: geordi vnc
or geordi vnc --setup
Launch a VNC session to the hidden screen where geordi cucumber
runs Selenium
tests.
When called with --setup
, will guide through the setup of VNC.
Runs the given command under bundle exec
if a Gemfile
is present in your
working directory. If no Gemfile
is present just runs the given command:
b spec spec/models
More information at http://makandracards.com/makandra/684-automatically-run-bundle-exec-if-required
Stores a timestamped database dump for the given Rails environment in ~/dumps
:
dumple development
More information at http://makandracards.com/makandra/1008-dump-your-database-with-dumple
Used by the geordi cucumber
command. Makes launchy open pages in the user's
browser, as opposed to opening it within the VNC window.
Copy lib/geordi/COMMAND_TEMPLATE
to lib/geordi/commands/your_command
and
edit it to do what you need it to do. Usually, it is hard to automatedly test
Geordi commands, so make sure you've manually tested it. You can do so by
calling your local geordi like so (adjust paths to your needs):
# @option -I: add directory to load path
ruby -I ../geordi/lib ../geordi/bin/geordi <command>
Don't forget to update this README. The whole geordi
section is auto-generated
by rake readme
.
Geordi is (partially) tested with Cucumber and Aruba. Run all tests with rake
.
Of course you're free to use geordi tests
;)
Note that Geordi still needs to support Ruby 1.8.7, so make sure you only use syntax that was valid back then (e.g. the :old => hash syntax). Unfortunately, it is really hard to get Geordi's tests running on 1.8.7, so you need to make sure it runs on 1.8.7 manually.
