There are several ways for installing Perceval on your system: from packages, from a docker image or from the source code.
Perceval can be installed using pip, a tool for installing Python packages. To do it, run the next command:
$ pip3 install perceval
A Perceval Docker image is available at DockerHub.
Detailed information on how to run and/or build this image can be found here.
To install from the source code you will need to clone the repository first:
$ git clone https://github.com/chaoss/grimoirelab-perceval.git
Then you can execute the following commands:
$ pip3 install -r requirements.txt
$ pip3 install .
In case you are a developer, you should execute the following commands to install Perceval in your working directory (option -e) and the packages of requirements_tests.txt.
$ pip3 install -r requirements.txt
$ pip3 install -r requirements_tests.txt
$ pip3 install -e .

To fetch bugs from Bugzilla, you have two options:
a) Use the traditional backend
$ perceval bugzilla 'https://bugzilla.redhat.com/' --backend-user user --backend-password pass --from-date '2016-01-01'
b) Use the REST API backend for Buzilla 5.0 (or higher) servers. We strongly recommend this backend when data is fetched from version servers >=5.0 because the retrieval process is much faster.
$ perceval bugzillarest 'https://bugzilla.mozilla.org/' --backend-user user --backend-password pass --from-date '2016-01-01'
$ perceval confluence 'https://wiki.opnfv.org/' --from-date '2016-01-01'
$ perceval discourse 'https://foro.mozilla-hispano.org/' --from-date '2016-01-01'
$ perceval dockerhub grimoirelab perceval
To run gerrit, you will need an authorized SSH private key:
$ eval `ssh-agent -s`
$ ssh-add ~/.ssh/id_rsa
Identity added: /home/user/.ssh/id_rsa (/home/user/.ssh/id_rsa)
To run the backend, execute the next command:
$ perceval gerrit --user user 'review.openstack.org' --from-date '2016-01-01'
To run this backend execute the next command. Take into account that to run this backend Git program has to be installed on your system.
$ perceval git 'https://github.com/chaoss/grimoirelab-perceval.git' --from-date '2016-01-01'
Git backend can also work with a Git log file as input. We recommend to use the next command to get the most complete log file.
git log --raw --numstat --pretty=fuller --decorate=full --parents --reverse --topo-order -M -C -c --remotes=origin --all > /tmp/gitlog.log
Then, to run the backend, just execute any of the next commands:
$ perceval git --git-log '/tmp/gitlog.log' 'file:///myrepo.git'
or
$ perceval git '/tmp/gitlog.log'
$ perceval github elastic logstash --from-date '2016-01-01'
The GitHub backend accepts the categories issue, pull_request and repository which allow to fetch the specific data.
$ perceval github --category issue elastic logstash
$ perceval gitlab elastic logstash --from-date '2016-01-01'
$ perceval googlehits "bitergia grimoirelab"
$ perceval groupsio 'updates' -t 'abcdefghijk' --from-date '2016-01-01'
In order to get an api_token, you should first subscribe to a group via the Groups.io website and then execute the following command:
$ curl "https://api.groups.io/v1/login" -u 123456: -d "email=<your email address>&password=<your password>"
In case you want to know the group names where your token is subscribed, you can use the following script: https://gist.github.com/valeriocos/676d90c58c56e2b17b882f2603283d39

$ perceval supybot 'http://channel.example.com' /tmp/supybot/
Telegram backend needs an API token to authenticate the bot. In addition and in order to fetch messages from a group or channel, privacy settings must be disabled. To know how to create a bot, to obtain its token and to configure it please read the Telegram Bots docs pages.
$ perceval telegram mybot -t 12345678abcdefgh --chats 1 2 -10
Twitter backend needs a bearer token to authenticate the requests. It can be obtained using the code available on GistGitHub: https://gist.github.com/valeriocos/7d4d28f72f53fbce49f1512ba77ef5f6
$ perceval twitter grimoirelab -t 12345678abcdefgh
Perceval comes with a comprehensive list of unit tests.
To run them, in addition to the dependencies installed with Perceval,
you need version 0.8.6 of httpretty.
Currently, latest version in pypi is 0.8.14,
which seems to have a bug exposed by some Perceval tests.
So, ensure you install 0.8.6, which is known to work with them:
$ pip install httpretty==0.8.6
$ cd tests
$ python3 run_tests.py
