Gertty

Gertty is a console-based interface to the Gerrit Code Review system.

As compared to the web interface, the main advantages are:

• Workflow -- the interface is designed to support a workflow similar to reading network news or mail. In particular, it is designed to deal with a large number of review requests across a large number of projects.
• Offline Use -- Gertty syncs information about changes in subscribed projects to a local database and local git repos. All review operations are performed against that database and then synced back to Gerrit.
• Speed -- user actions modify locally cached content and need not wait for server interaction.
• Convenience -- because Gertty downloads all changes to local git repos, a single command instructs it to checkout a change into that repo for detailed examination or testing of larger changes.

Installation

Debian

Gertty is packaged in Debian and is currently available in:

• unstable
• testing
• stable

You can install it with:

apt-get install gertty

Fedora

Gertty is packaged starting in Fedora 21. You can install it with:

dnf install python-gertty

openSUSE

Gertty is packaged for openSUSE 13.1 onwards. You can install it via 1-click install from the Open Build Service.

Gentoo

Gertty is available in the main Gentoo repository. You can install it with:

emerge gertty

Arch Linux

Gertty packages are available in the Arch User Repository packages. You can get the package from:

https://aur.archlinux.org/packages/python2-gertty/

Source

When installing from source, it is recommended (but not required) to install Gertty in a virtualenv. To set one up:

virtualenv gertty-env
source gertty-env/bin/activate

To install the latest version from the cheeseshop:

pip install gertty

To install from a git checkout:

pip install .

Gertty uses a YAML based configuration file that it looks for at ~/.gertty.yaml. Several sample configuration files are included. You can find them in the examples/ directory of the source distribution or the share/gertty/examples directory after installation.

Select one of the sample config files, copy it to ~/.gertty.yaml and edit as necessary. Search for CHANGEME to find parameters that need to be supplied. The sample config files are as follows:

minimal-gertty.yaml

Only contains the parameters required for Gertty to actually run.

reference-gertty.yaml

An exhaustive list of all supported options with examples.

openstack-gertty.yaml

A configuration designed for use with OpenStack's installation of Gerrit.

googlesource-gertty.yaml

A configuration designed for use with installations of Gerrit running on googlesource.com.

You will need your Gerrit password which you can generate or retrieve by navigating to Settings, then HTTP Password.

Gertty uses local git repositories to perform much of its work. These can be the same git repositories that you use when developing a project. Gertty will not alter the working directory or index unless you request it to (and even then, the usual git safeguards against accidentally losing work remain in place). You will need to supply the name of a directory where Gertty will find or clone git repositories for your projects as the git-root parameter.

The config file is designed to support multiple Gerrit instances. The first one is used by default, but others can be specified by supplying the name on the command line.

Usage

After installing Gertty, you should be able to run it by invoking gertty. If you installed it in a virtualenv, you can invoke it without activating the virtualenv with /path/to/venv/bin/gertty which you may wish to add to your shell aliases. Use gertty --help to see a list of command line options available.

Once Gertty is running, you will need to start by subscribing to some projects. Use 'L' to list all of the projects and then 's' to subscribe to the ones you are interested in. Hit 'L' again to shrink the list to your subscribed projects.

In general, pressing the F1 key will show help text on any screen, and ESC will take you to the previous screen.

Gertty works seamlessly offline or online. All of the actions that it performs are first recorded in a local database (in ~/.gertty.db by default), and are then transmitted to Gerrit. If Gertty is unable to contact Gerrit for any reason, it will continue to operate against the local database, and once it re-establishes contact, it will process any pending changes.

The status bar at the top of the screen displays the current number of outstanding tasks that Gertty must perform in order to be fully up to date. Some of these tasks are more complicated than others, and some of them will end up creating new tasks (for instance, one task may be to search for new changes in a project which will then produce 5 new tasks if there are 5 new changes).

If Gertty is offline, it will so indicate in the status bar. It will retry requests if needed, and will switch between offline and online mode automatically.

If you review a change while offline with a positive vote, and someone else leaves a negative vote on that change in the same category before Gertty is able to upload your review, Gertty will detect the situation and mark the change as "held" so that you may re-inspect the change and any new comments before uploading the review. The status bar will alert you to any held changes and direct you to a list of them (the F12 key by default). When viewing a change, the "held" flag may be toggled with the exclamation key (!). Once held, a change must be explicitly un-held in this manner for your review to be uploaded.

If Gertty encounters an error, this will also be indicated in the status bar. You may wish to examine ~/.gertty.log to see what the error was. In many cases, Gertty can continue after encountering an error. The error flag will be cleared when you leave the current screen.

To select text (e.g., to copy to the clipboard), hold Shift while selecting the text.

MacOS

The MacOS terminal blocks ctrl+o, which is the default search key combo in Gertty. To fix this, a custom keymap can be used on MacOS which modifies the search key combo. For example:

keymaps:
  - name: default # MacOS blocks ctrl+o
    change-search: 'ctrl s'
    interactive-search: 'ctrl i'

Terminal Integration

If you use rxvt-unicode, you can add something like the following to .Xresources to make Gerrit URLs that are displayed in your terminal (perhaps in an email or irc client) clickable links that open in Gertty:

URxvt.perl-ext:           default,matcher
URxvt.url-launcher:       sensible-browser
URxvt.keysym.C-Delete:    perl:matcher:last
URxvt.keysym.M-Delete:    perl:matcher:list
URxvt.matcher.button:     1
URxvt.matcher.pattern.1:  https:\/\/review.example.org/(\\#\/c\/)?(\\d+)[\w]*
URxvt.matcher.launcher.1: gertty --open $0

You will want to adjust the pattern to match the review site you are interested in; multiple patterns may be added as needed.
