Description
-----------
Changelog generator based on milestone or tags for github.

Installation
------------

Using pip

::

    pip install loghub

Using conda

::

    conda install loghub -c conda-forge

or

::

    conda install loghub -c spyder-ide


Usage
-----

loghub can be used to generate changelog based on milestones or on tags.

In projects where milestones are used to track a release we can use for example:

.. code-block:: text

    loghub spyder-ide/spyder --milestone v3.0


In projects where milestones are used to track chunks of work but not releases,
we can use tags to get the changes after the latest release, for example:

.. code-block:: text

    loghub spyder-ide/spyder --since-tag v3.0.0b7


Or if loghub is used to generate old changelogs (or update changelogs),
we can also use tags to limit the range , for example:

.. code-block:: text

    loghub spyder-ide/spyder --since-tag v3.0.0b7 --until-tag v3.0.0


For private repos, just add the username and password arguments, for example:

.. code-block:: text

    loghub spyder-ide/spyder --since-tag v3.0.0b7 --since-tag v3.0.0 --username <username> --password <password>


Or, just add the username and a password prompt will appear, for example:

.. code-block:: text

    loghub spyder-ide/spyder --since-tag v3.0.0b7 --since-tag v3.0.0 --username <username>


Or generate a Github access token and use that instead, for example:

.. code-block:: text

    loghub spyder-ide/spyder --since-tag v3.0.0b7 -until-tag v3.0.0 --token <token>


**Important**

Because of the Github API rate limitations it is advised to always use authentication
by either access token or user and password.


Advanced Usage
--------------

Filter PR base branch
~~~~~~~~~~~~~~~~~~~~~

Pull requests to display can be filtered depending on the branch they were
merge against (base branch):

.. code-block:: text

    loghub spyder-ide/spyder --branch 3.x


Filter issues/PRs by labels
~~~~~~~~~~~~~~~~~~~~~~~~~~~

To filter issues to display, we can use a regular expression:

.. code-block:: text

    loghub spyder-ide/spyder --issue-label-regex "Type.*" --milestone v3.1

This will filter all the issues that start with *Type*

The same can be done with PRs

.. code-block:: text

    loghub spyder-ide/spyder --pr-label-regex "<some-regex>" --milestone v3.1


Group issues by label
~~~~~~~~~~~~~~~~~~~~~

Issues displayed can be grouped by labels:

.. code-block:: text

    loghub spyder-ide/spyder --issue-label-group "Type-Bug" "Bugs Fixed" --issue-label-group "Type-Enhancement" "New Features" --milestone v3.1

This will result in issues being grouped in two sections with the headings
*Bugs Fixed* and *New Features* respectively.

Output format
~~~~~~~~~~~~~

Loghub provides two formats:

* ***changelog***, which is the default and includes links to issues and PRs
* ***release***, which does not include links

.. code-block:: text

    loghub spyder-ide/spyder --milestone v3.1 --format release

Custom templates
~~~~~~~~~~~~~~~~

Loghub uses Jinja2 templates to format the output. If the current template
does not your needs, you can copy the default `templates <https://github.com/spyder-ide/loghub/tree/master/loghub/templates>`_ 
and create a new one and provide the path to it as:

.. code-block:: text

    loghub spyder-ide/spyder --milestone v3.1 --template <PATH_TO_TEMPLATE>
