* Types of contributions
:PROPERTIES:
:CUSTOM_ID: types-of-contributions
:END:

Every contribution to Org is very welcome.  Here is a list of areas
where your contribution will be useful:

- you can submit *bug reports* -- Before sending a bug report, make sure
  you have read this section of Org's manual: [[https://orgmode.org/org.html#Feedback][Feedback]] You can also
  read this great text: "[[http://www.chiark.greenend.org.uk/~sgtatham/bugs.html][How to Send Bug Reports Effectively]]"

- you can submit *patches* -- You can submit patches to the mailing
  list.  See the [[For Org contributors: preferred way of submitting patches][Preferred way of submitting patches]] section for
  details.  You can run =make test= to check that your patch does not
  introduce new bugs.

  If your patch is against a file that is part of Emacs, then your
  total contribution (all patches you submit) should change /less than
  15 lines/ (See the [[http://git.savannah.gnu.org/cgit/emacs.git/tree/CONTRIBUTE][CONTRIBUTE file in GNU Emacs]].)  If you contribute
  more, you have to assign the copyright of your contribution to the
  Free Software Foundation (see below).

- You can submit material to the *Worg* website -- This website is made
  of Org files that you can contribute to.  Learn what Worg is [[file:worg-about.org][about]]
  and how to contribute to it [[file:worg-git.org][through git]].

- You can submit *feature requests* -- Org is already mature, but new
  ideas keep popping up.  If you want to request a feature, it might
  be a good idea to have a look at the current [[https://orgmode.org/worg/org-issues.html][Issue tracking file]]
  which captures both bug reports and feature requests.  Or dig into
  the mailing list for possible previous discussions about your idea.
  If you cannot find back your idea, formulate it as detailed as
  possible, if possible with examples, and send it to the mailing
  list.

- You can submit Org *add-ons* -- there are many Org add-ons.
  - The best way is to submit your code to [[file:org-mailing-list.org][the mailing list]] to discuss
    it with people.
  - If it is useful, you might consider contributing it to the
    =lisp/contrib/= directory in the git repository.  It will be
    reviewed, and if it passes, it will be included.  Ask help from
    [[file:org-people.org][Eric Schulte]] for this step.  The =lisp/contrib/= directory is
    somehow relaxed: it is not distributed with Emacs, and does not
    require a formal copyright assignment.
  - If you decide to sign the [[*Copyright issues when contributing to Emacs Org mode][assignment contract with the FSF]], we
    might include your contribution in the distribution, and then in
    GNU Emacs.

* Copyright issues when contributing to Emacs Org mode
:PROPERTIES:
:CUSTOM_ID: copyright-issues
:END:

Org is made of many files.  Most of them are also distributed as part
of GNU Emacs.  These files are called the /Org core/, and they are all
copyrighted by the [[http://www.fsf.org][Free Software Foundation, Inc]].  If you consider
contributing to these files, your first need to grant the right to
include your works in GNU Emacs to the FSF.  For this you need to
complete [[https://orgmode.org/request-assign-future.txt][this form]], and send it to [[mailto:assign@gnu.org][assign@gnu.org]].  The FSF will send
you the assignment contract that both you and the FSF will sign.
Please let the Org mode maintainer know when this process is complete.
Some people consider this assignment process a hassle.  I don't want
to discuss this in detail here - there are some good reasons for
getting the copyright registered, an example is discussed in this
[[http://twit.tv/floss117][FLOSS weekly podcast]].  Furthermore, by playing according to the Emacs
rules, we gain the fantastic advantage that every version of Emacs
ships with Org mode already fully built in.  So please consider doing
this - it makes our work as maintainers so much easier, because we can
then take your patches without any additional work.

If you want to learn more about /why/ copyright assignments are
collected, read this: [[http://www.gnu.org/licenses/why-assign.html][Why the FSF gets copyright assignments from
contributors?]]

By submitting patches to emacs-orgmode@gnu.org, or by pushing changes
to the Org mode repository, you are placing these changes under the
same licensing terms as those under which GNU Emacs is published.

#+begin_example
;; GNU Emacs is free software: you can redistribute it and/or modify
;; it under the terms of the GNU General Public License as published by
;; the Free Software Foundation, either version 3 of the License, or
;; (at your option) any later version.
#+end_example

If at the time you submit or push these changes you do have active
copyright assignment papers with the FSF, for future changes to either
Org mode or to Emacs, this means that copyright to these changes is
automatically transferred to the FSF.  The Org mode repository is seen
as upstream repository for Emacs, anything contained in it can
potentially end up in Emacs.  If you do not have signed papers with
the FSF, only changes to files in the =contrib/= part of the repository
will be accepted, as well as very minor changes (so-called /tiny
changes/) to core files.  We will ask you to sign FSF papers at the
moment we attempt to move a =contrib/= file into the Org core, or into
Emacs.

** Git branches

Please read [[https://code.orgmode.org/bzg/org-mode/src/master/README_maintainer][README_maintainer]] file within Org's repository.

** Pushing your first commit

1. Create an account on https://code.orgmode.org
2. Add your public key to the account
3. Ask [[mailto:bzgATgnuDOTorg][Bastien]] to be added as a collaborator on the repository
4. Clone =org-mode.git=: =~$ git clone git@code.orgmode.org:bzg/org-mode.git=
5. Commit your changes against the code and the documentation.
6. Run =make test=
7. If the tests pass, push your changes.

If you are undertaking big changes, please create a dedicated branch
and make sure you have a clean commit history before merging it into
the maint or master branch.

** Taking care of the manual in both branches

- When you make a change in the master branch, update
  doc/org-manual.org accordingly.

- When you make a change in the maint branch, update doc/org.texi in
  maint and doc/org-manual.org when you merge maint into master.

* For Org contributors: preferred way of submitting patches
:PROPERTIES:
:CUSTOM_ID: patches
:END:

** Coding conventions

Org is part of Emacs, so any contribution should follow the [[http://www.gnu.org/software/emacs/manual/html_node/elisp/Coding-Conventions.html][GNU Emacs
Lisp coding conventions]] described in Emacs manual.

** Sending patch with git

Org mode is developed using /git/ as the version control system.  Git
provides an amazing framework to collaborate on a project.  Git can be
used to make patches and send them via email -- this is perfectly fine
for major and minor changes.

When sending a patch (either using =git diff= or =git format-patch=)
please *always add a properly formatted Emacs ChangeLog entry*.  See
[[#commit-messages][this section]] for details on how to create such a ChangeLog.

** Sending commits

For every patch you send, we suggest to use =git format-patch=.

This is easy for small patches and more consequent ones.  Sometimes,
you might even want to work in several steps and send each commit
separately.  Here is the suggested workflow:

#+begin_quote
:   ~$ git pull                 # make sure your repo is up to date
:   ~$ git branch my-changes    # create a new branch from master
:   ~$ git checkout my-changes  # switch to this new branch

  ... make some changes (1) ...

:   ~$ git commit -a -m "This is change (1)"  # Commit your change

  ... make another change (2) ...

:   ~$ git commit -a -m "This is change (2)"  # Commit your change
:   ~$ git format-patch master                # Creates two patches

  ... Then two patches for your two commits are ready to be sent to
  the list.
#+end_quote

Write useful commit messages: please provide 1) a reason for it in
your email and 2) a ChangeLog entry in the commit message (see [[#commit-messages][this section]] on how to format a ChangeLog entry.)

** Sending quick fixes for testing purpose

If you want to send a quick fix that needs to be further tested by
other people (before you submit a real patch), here is how you can do:

#+begin_quote
  This command will make a patch between the staging area (in your
  computer), and the file you modified:

  : git diff -p org-whatever.el > org-whatever.el.diff

  If you already committed your changes to your index (staging area), then
  you should compare against a particular branch (in this example,
  origin/master):

  : git diff -p origin/master org-whatever.el > org-whatever.el.diff

  You email the output to the mailing list, adding =[PATCH]= to the
  subject, and description of what you fixed or changed.
#+end_quote

Note that small patches sent like this still need to have a ChangeLog
entry to be applied.  If your patch looks good to you, it's always
better to send a patch through =git format-patch=.

** Sharing changes from a public branch

For more significant contributions, the best way to submit patches is
through public branches of your repository clone.

1. Clone our git repository at =https://code.orgmode.org/bzg/org-mode=.
   You can clone using any of the commands below.

   : git clone git@code.orgmode.org:bzg/org-mode.git
   : git clone https://code.orgmode.org/bzg/org-mode.git

   The url using the git protocol is preferred.  If you are behind a
   firewall that blocks ~git://~, you can use the https url.

2. Create a repository that can be publicly accessed, for example on
   /GitHub/ or on your own server.

3. Push your topic branches (and optionally the master branch) to your
   public repository.

   Define a remote for your public repository you push topics to.

   : git remote add REMOTE URL-GOES-HERE

   Push branches to the remote

   : git push REMOTE BRANCH1 [BRANCH2 BRANCH3 ...]

   e.g.

   : git remote add github ssh://.../     # Done once to define the remote 'github'
   : git push github my-topic

4. Do your work on topic-specific branches, using a branch name that
   relates to what you are working on.

5. Often do

   : git remote update

   to pull commits from all defined remote repositories.

6. When you have something workable, publish the git path and branch
   name on the mailing list, so that people can test it and review
   your work.

7. After your topic has been merged to the project master branch you
   can delete the topic on your local and remote repositories.

   : git branch -d NEWTOPIC
   : git push REMOTE :NEWTOPIC

The instructions above are generally useful to let people test new
features before sending the patch series to the mailing list, but the
patches remain the preferred way of receiving contributions.

* Commit messages and ChangeLog entries
:PROPERTIES:
:CUSTOM_ID: commit-messages
:END:

We have decided to no longer keep a ChangeLog file to record changes
to individual functions.

A commit message should be constructed in the following way:

- Line 1 of the commit message should always be a short description of
  the overall change.  Line 1 does /not/ get a dot at the end and does
  not start with a star.  Generally, it starts with the filename that
  has been changed, followed by a colon.

- Line 2 is an empty line.

- In line 3, the ChangeLog entry should start.  A ChangeLog entry
  looks like [[https://orgmode.org/cgit.cgi/org-mode.git/commit/?id%3Dd49957ef021e256f19092c907d127390d39ec1ed][this]]:

  : * org-timer.el (org-timer-cancel-timer, org-timer-stop): Enhance
  : message.
  : (org-timer-set-timer): Use the number of minutes in the Effort
  : property as the default timer value. Three prefix arguments will
  : ignore the Effort value property.

- After the changelog, another empty line should come before any
  additional information that the committer wishes to provide in order
  to explain the patch.

- If the change is a minor change made by a committer without
  copyright assignment to the FSF, the commit message should also
  contain the cookie =TINYCHANGE= (anywhere in the message).  When we
  later produce the ChangeLog file for Emacs, the change will be
  marked appropriately.

- Variables and functions names are quoted like `this' (backquote and
  single quote).

- Sentences should be separated by two spaces.

- Sentences should start with an uppercase letter.

- Avoid the passive form: i.e., use "change" instead of "changed".

Here is an example for such a message:

#+begin_example
  org-capture.el: Fix the case of using a template file

  ,* lisp/org-capture.el (org-capture-set-plist): Make sure txt is a
  string before calling `string-match'.
  (org-capture-templates): Fix customization type.

  ,* doc/org.texi (Capture): Document using a file for a template.

  The problem here was that a wrong keyword was given in the
  customization type.  This let to a string-match against a list value.

  Modified from a patch proposal by Johan Friis.

  TINYCHANGE
#+end_example

If you are using /magit.el/ in Emacs, the ChangeLog for such entries
are easily produced by pressing =C= in the diff listing.

Another option to produce the entries is to use `C-x 4 a' in the
changed function or in the diff listing.  This will create entries in
the ChangeLog file, and you can then cut and paste these to the commit
message and remove the indentation.
