Information on developing Gramps addons

If you are looking for addons to install, visit: Third-party Addons

Gnome-important.png
Note that this article anticipates that most addons will be developed under Linux.

(Linux is the principal development platform.) While it is possible to do so under Windows or MacOS, some of the steps will differ and the documented processes have not been as thoroughly reviewed. So developer beware.
See Portal:Developers

If you are developing a Third-party Addon; this page documents the API, methods, and best practices for Gramps 6.0 and later.

What can addons extend?

Addons for Gramps can extend the program in many different ways. You can add any of the following types of addons:

  • Importer (IMPORT) - adds additional file format import options to Gramps
  • Exporter (EXPORT) - adds additional file format export options to Gramps
  • Gramplet (GRAMPLET) - adds a new interactive interface section to a Gramps view mode, which can be activated by right-clicking on the dashboard View or from the menu of the Sidebar/Bottombar in the other view categories.
  • Gramps View (mode) (VIEW) - adds a new view mode to the list of views available within a View Category
  • Map Service (MAPSERVICE) - adds new mapping options to Gramps
  • Plugin lib (GENERAL) - libraries that are present giving extra functionality. Can add, replace and or modifies builtin Gramps options.
  • Quickreport/Quickview (QUICKREPORT) - a view that you can run by right-clicking on object, or if a person quickview, then through the Quick View Gramplet
  • Report (REPORT) - adds a new output report / includes Website - output a static genealogy website based on your Gramps Family Tree data.
  • Rule (RULE) - adds new filter rules. — ⚡new for version 5.1
  • Tool (TOOL) - adds a utility that helps process data from your family tree.
  • Doc creator (DOCGEN)
  • Relationships (RECALC)
  • Sidebar (SIDEBAR)
  • Database (DATABASE) - add support for another database backend. — ⚡new for version 5.0
  • Thumbnailer (THUMBNAILER) — ⚡new for version 5.2
  • Citation formatter (CITE) — ⚡new for version 5.2

Writing an addon

Writing an addon is fairly straightforward if you have just a little bit of Python experience. And sharing your addon is the right thing to do. The general steps to writing an addon and sharing your own addons are:

  1. Develop your addon
  2. Create a Gramps Plugin Registration file (.gpr.py)
  3. Addon Checklist
  4. Create a Pull Request for your addon
  5. Announce it on the Gramps Forum - Let users know it exist and how to use it.
  6. Support it through the issue tracker
  7. Maintain the code as Gramps continues to evolve

We'll now expand upon each of these steps individually.

Develop your addon

The addons-source repository holds the source code for the addons with branches holding the version for different gramps. If you are working on an addon for gramps for the current Gramps 6.0 public release, be sure to use the maintenance/gramps60 git branch. Addons are not updated in the master branch.

Example commands are shown below referring to the public release rather than the master branch.

The developers are currently merging changes to the most recent maintenance branch into master as necessary, so you don't have to do anything for that.

The addons-source git repository has the following structure, with the code for each addon in its own folder:

  • /addons-source
    • /IndividualNameOfAddon1
    • /IndividualNameOfAddon2
    • ...

The addons git repository holds built versions of the addons for each release of Gramps. As an addon developer, you don't have to do anything with this repository. You only use this if you want to manage an addon repository of your own. The repository has the following structure:

Get a local copy of Gramps and its addons

These steps show how to download the addon sources.

  1. Get an https://github.com/join account if you don't already have one.
  2. Request GIT write access for the https://github.com/gramps-project/addons-source project by emailing the gramps-devel mailing list

See also git introduction for instructions on installing git and getting basic settings configured. Also Connecting to GitHub with SSH will help with setting up credentials for GitHub. To fully build and advertise a new addon will require local copies of the three repositories, the 'addons-source', 'addons' and the main Gramps source 'gramps'.

This wiki assumes that all three git repositories local locations are put into the same base directory and named with the repository names in order for the make.py script commands to work as shown. From the base directory, run the following commands to create a copy of each repository. If you want to use SSH; 

git clone [email protected]:gramps-project/addons-source.git addons-source
git clone [email protected]:gramps-project/addons.git addons
git clone [email protected]:gramps-project/gramps.git gramps

or if you want to use a web url: 

git clone https://github.com/gramps-project/addons-source.git addons-source
git clone https://github.com/gramps-project/addons.git addons
git clone https://github.com/gramps-project/gramps.git gramps

To switch to a local copy of the gramps60 maintenance branch: 

cd addons-source
git checkout -b gramps60 origin/maintenance/gramps60

or to view in the master branch: 

cd addons-source
git checkout -b master origin/master


Create your addon subdirectory

  • Make a new project directory in addons-source:
mkdir NewProjectName

Follow the development API for your tool

Create your NewProjectName.py and NewProjectName.gpr.py files.

Follow the development API for your tool, report, view, or Gramplets development. Place all of your associated .py, .glade, etc. files in this directory. For general information on Gramps development see Portal:Developers and Writing a Plugin specifically.

Test your addon as you develop

Gnome-important.png
10436 Symlinks to folders in gramps plugin dir are not scanned

To test your addon as you develop it is suggested that you copy your NewProjectName plugin into your Gramps user plugin directory from your addon development directory, prior to testing. Or just edit in the Gramps user plugin directory until it is ready to publish, then copy back to your addon development directory.

Your installed Gramps will search this folder (and subdirectories) for .gpr.py files, and add them to the plugin list.

If you have code that you want to share between addons, you don't need to do anything special. Gramps adds each directory in which a .gpr.py is found onto the PYTHONPATH which is searched when you perform an import. Thus "import NewProjectName" will work from another addon. You should always make sure you name your addons with a name appropriate for Python imports.


Config

Some addons may want to have persistent data (data settings that remain between sessions). You can handle this yourself, or you can use Gramps' builtin configure system.

At the top of the source file of your addon, you would do this: 

from config import config as configman
config = configman.register_manager("grampletname")
# register the values to save:
config.register("section.option-name1", value1)
config.register("section.option-name2", value2)
...
# load an existing file, if one:
config.load()
# save it, it case it didn't exist:
config.save()

This will create the file "grampletname.ini" and put in the same directory as the addon. If the config file already exists, it remains intact. The natural location for .ini files would be in the directory in which the addon is installed. (Using the main gramps.ini file for addon preferences could potentially lead to a conflict between addons.) Other locations and file formats are possible. The Gramps architect recommends leaving this decision to the addon developer.

In the addon, you can then: 

x = config.get("section.option-name1")
config.set("section.option-name1", 3)

and when this code is exiting, you might want to save the config. In a Gramplet that would be: 

def on_save(self):
    config.save()

If your code is a system-level file, then you might want to save the config in the Gramps system folder: 

config = configman.register_manager("system", use_config_path=True)

This, however, would be rare; most .ini files would go into the plugins directory.

In other code that might use this config file, you would do this: 

from config import config as configman
config = configman.get_manager("grampletname")
x = config.get("section.option-name1")

Localization

For general help on translations in Gramps, see Coding for translation. However, that will only use translations that come with Gramps, or allows you to contribute translations to the Gramps core. To have your own managed translations that will be packaged with your addon, read the rest of this page. Note that these instructions will only work for Python strings, if you have a glade file, it will not get translated.

For any addon which you have translations into other languages, you will need to add a way to retrieve the translation. You need to add this to the top of your NewProjectName.py file: 

from gramps.gen.const import GRAMPS_LOCALE as glocale
 _ = glocale.get_addon_translator(__file__).gettext


Then you can use the standard "_()" function to translate phrases in your addon.

You can use one of a few different types of translation functions:

  1. gettext
  2. lgettext
  3. ngettext
  4. lngettext
  5. sgettext

These have become obsolete in Gramps 4; gettext, ngettext, and sgettext always return translated strings in unicode for consistent portability between Python 2 and Python3.

See the python documentation for documentation of gettext and ngettext. The "l" versions return the string encoded according to the currently set locale; the "u" versions return unicode strings in Python2 and are not available in Python 3.

sgettext is a Gramps extension that filters out clarifying comments for translators, such as 

_("Remaining names | rest")

Where "rest" is the English string that we want to present and "Remaining names" is a hint for translators.

Files included in addon distribution

The process to make the download compressed tar file automatically includes the following files:

  • *.py
  • *.glade
  • *.xml
  • *.txt
  • locale/*/LC_MESSAGES/*.mo

Starting with Gramp 5.0, if you have additional files beyond those listed above, you should create a MANIFEST file in the root of your addon folder listing the files (or pattern) one per line, like this sample MANIFEST file: 

Addon/README.md
Addon/extra_dir/*
Addon/help_files/docs/help.html

Create a Gramps Plugin Registration file

First, create the NewProjectName.gpr.py file. The registration takes this general form: 

register(PTYPE,
     gramps_target_version = "6.0",
     version = "1.0.0",
     ATTR = value,
)

PTYPE values include: TOOL, GRAMPLET, REPORT, QUICKVIEW (formerly QUICKREPORT), IMPORT, EXPORT, DOCGEN, GENERAL, MAPSERVICE, VIEW, RELCALC, SIDEBAR, DATABASE, RULE, THUMBNAILER, and CITE.


ATTR depends on the PTYPE. But you must have gramps_target_version and addon version. gramps_target_version should be a string of the form "X.Y" version number matching Gramps X major, Y minor integer. version is a string of the form "X.Y.Z" representing the version of your addon. X, Y, and Z should all be integers.

Be sure to include attributes for author name(s) and email(s) in the form of an array of comma-separated strings.

There is an additional set of attributes, maintainers and maintainers_email. — ⚡new for version 5.2 If you, the author, are also the maintainer it will be identical to the author attributes, but you may also designate a maintainer, in which case the maintainer will become the primary point of contact.

Here is a sample Tool GPR file: 

register(TOOL, 
         id    = 'AttachSource',
         name  = _("Attach Source"),
         description =  _("Attaches a shared source to multiple objects."),
         version = '1.0.0',
         gramps_target_version = '6.0',
         status = STABLE,
         fname = 'AttachSourceTool.py',
         authors = ["Douglas S. Blank"],
         authors_email = ["[email protected]"],
         maintainers = ["Douglas S. Blank"],
         maintainers_email = ["[email protected]"],
         category = TOOL_DBPROC,
         toolclass = 'AttachSourceWindow',
         optionclass = 'AttachSourceOptions',
         tool_modes = [TOOL_MODE_GUI],
         help_url = "Addon:AttachSourceTool"
         )

You can see examples of the kinds of addons here (for example, see gramps/plugins/drawreport/drawplugins.gpr.py) and see the full documentation in the master/gramps/gen/plug/_pluginreg.py comments and docstrings.

Note that this .gpr.py will automatically use translations if you have them (see below). That is, the function "_" is predefined to use your locale translations; you only need to mark the text with _("TEXT") and include a translation of "TEXT" in your translation file. For example, in the above example, _("Attach Source") is marked for translation. If you have developed and packaged your addon with translation support, then that phrase will be converted into the user's language.

Report plugins

The possible report categories are (gen/plug/_pluginreg.py): 

#possible report categories
CATEGORY_TEXT       = 0
CATEGORY_DRAW       = 1
CATEGORY_CODE       = 2
CATEGORY_WEB        = 3
CATEGORY_BOOK       = 4
CATEGORY_GRAPHVIZ   = 5
CATEGORY_TREE       = 6
REPORT_CAT          = [ CATEGORY_TEXT, CATEGORY_DRAW, CATEGORY_CODE,
                        CATEGORY_WEB, CATEGORY_BOOK, CATEGORY_GRAPHVIZ, CATEGORY_TREE]

Each report category has a set of standards and interface. The categories CATEGORY_TEXT and CATEGORY_DRAW use the Document interface of Gramps. See also Report API for a draft view on this.

The application programming interface or API for reports is treated at Report-writing_tutorial. For general information on Gramps development see Portal:Developers and Writing a Plugin specifically.

General plugins

The plugin framework also allows you to create generic plugins for use. This includes the ability to create libraries of functions, and plugins of your own design.

Example: A library of functions

In this example, a file name library.py will be imported at time of registration (when Gramps starts): 

# file: library.gpr.py

register(GENERAL, 
   id    = 'My Library',
   name  = _("My Library"),
   description =  _("Provides a library for doing something."),
   version = '1.0',
   gramps_target_version = '6.0',
   status = STABLE,
   fname = 'library.py',
   load_on_reg = True,
  )

The code in the file library.py will be imported when Gramps begins. You can access the loaded module in other code by issuing an "import library" as Python keeps track of files already imported. However, the amount of useful code that you can run when the program is imported is limited. You might like to have the code do something that requires a dbstate or uistate object, and neither of these is available when just importing a file.

If "load_on_reg" was not True, then this code would be unavailable until manually loaded. There is no automatic mechanism in Gramps to load GENERAL plugins automatically.

In addition to importing a file at startup, one can also run a single function inside a GENERAL plugin, and it will be passed the dbstate, the uistate, and the plugin data. The function must be called "load_on_reg", and take those three parameters, like this: 

# file: library.py

def load_on_reg(dbstate, uistate, plugin):
    """
    Runs when plugin is registered.
    """
    print("Hello World!")

Here, you could connect signals to the dbstate, open windows, etc.

Another example of what one can do with the plugin interface is to create a general purpose plugin framework for use by other plugins. Here is the basis for a plugin system that:

  • allows plugins to list data files
  • allows the plugin to process all of the data files

First, the gpr.py file: 


register(GENERAL, 
  id    = "ID",
  category = "CATEGORY",
  load_on_reg = True,
  process = "FUNCTION_NAME",
  )

This example uses three new features:

  1. GENERAL plugins can have a category
  2. GENERAL plugins can have a load_on_reg function that returns data
  3. GENERAL plugins can have a function (called "process") which will process the data

If you (or someone else) create additional general plugins of this category, and they follow your load_on_reg data format API, then they could be used just like your original data. For example, here is an additional general plugin in the 'WEBSTUFF' category: 

# anew.gpr.py

register(GENERAL, 
  id    = 'a new plugin',
  category = "WEBSTUFF",
  version = '1.0',
  gramps_target_version = '6.0',
  data = ["a", "b", "c"],
  )

This doesn't have load_on_reg = True, nor does it have a fname or process, but it does set the data directly in the .gpr.py file. Then we have the following results: 

>>> from gui.pluginmanager import GuiPluginManager
>>> PLUGMAN = GuiPluginManager.get_instance()
>>> PLUGMAN.get_plugin_data('WEBSTUFF')
["a", "b", "c", "Stylesheet.css", "Another.css"]
>>> PLUGMAN.process_plugin_data('WEBSTUFF')
["A", "B", "C", "STYLESHEET.CSS", "ANOTHER.CSS"]

Registered GENERAL Categories

The following are the published secondary plugins API's (type GENERAL, with the following categories):

WEBSTUFF

A sample gpr.py file: 

# stylesheet.gpr.py

register(GENERAL, 
  id    = 'system stylesheets',
  category = "WEBSTUFF",
  name  = _("CSS Stylesheets"),
  description =  _("Provides a collection of stylesheets for the web"),
  version = '1.0',
  gramps_target_version = '6.0',
  fname = "stylesheet.py",
  load_on_reg = True,
  process = "process_list",
  )

Here is the associated program: 

# file: stylesheet.py

def load_on_reg(dbstate, uistate, plugin):
    """
    Runs when plugin is registered.
    """
    return ["Stylesheet.css", "Another.css"]

def process_list(files):
    return [file.upper() for file in files]

Filters

For example: 

register(GENERAL,
   category="Filters",
   ...
   load_on_reg = True
)

def load_on_reg(dbstate, uistate, plugin):
    # returns a function that takes a namespace, 'Person', 'Family', etc.

    def filters(namespace):
        print("Ok...", plugin.category, namespace, uistate)
        # return a Filter object here
    return filters

List the Prerequistes your addon depends on

In your gpr file, you can have a line like:

depends_on = ["libwebconnect"],

which is a list of plug-in identifier's from other gpr files. This example will ensure that libwebconnect is loaded before your addon. If that ID can't be found, or you have a cycle (circular import), then your addons won't be loaded. The Gramps architect summarizes: "The depends_on list is used to specify other plugins which the plugin depends on. These will be installed automatically."

example code used in the Addon:Web_Connect_Pack that references libwebconnect Prerequistes RUWebPack.gpr.py#L17

This means that common Prerequisites can be shared between addons. So that code can be maintained in its own gpr/addon file instead of synchronizing the maintenance of multiple copies across various silos.

Additional requirements properties were implemented in the Registration Options to specify prerequisites for plug-ins: requires_mod (modules), requires_gi (GObject introspection) and requires_exe (executable). — ⚡new for version 5.2

Announce the addon

Join the Gramps Forum and announce it to the users with general information on why you created and how to use it.

Support it through issue tracker

Become a user on the Gramps MantisBT (Mantis BugTracker). and please check it regularly. There is no automated notification of issues (and possible feature requests) related to your addon when reported by users.

Users tend to not understand coding and they make assumptions. So be kind and guiding if a report is ambiguous or inaccurate. A negative remark from an addon developer or anyone can be very discouraging.

Maintain the code as Gramps continues to evolve

Tango-Dialog-information.png
When submitting an update the patch part of the version number MAJOR.MINOR.PATCH is updated during the addon build process e.g. 1.1.3 to 1.1.4

You can find this step in addons-source/make.py.[1]


Remember that Gramps addons exist for many reasons and there are many Gramps developers that do support addons in various ways (translations, triage, keeping in sync with master, download infrastructure, etc).

Some reasons why the addons exist; they provide:

  • A quick way for anyone to share their work; the Gramps-project has never denied adding a addon.
  • A method to continuously update and develop a stand-alone component, often before being officially accepted.
  • A place for controversial plugins that will never be accepted into core, but are loved by many users (eg, Data Entry Gramplet).
  • A place for experimental components to live.

Example code adding common enhancements

Repository Management

There are steps that only the repo manager need complete once the gramplet has a PR submitted. If you are not managing a repo, you do not need to do any of these steps.

Gnome-important.png
These instructions, the make.py script etc.

are designed to operate in a Linux environment. They won't work on Windows without modifications.

Prerequisites

  • Gramps uses Python version 3.2 or higher. You must have at least that version installed. If you have installed Gramps 4.2 or higher on your Linux system already, then a sufficient version of Python will be present. If you have more than one version of Python installed, then you must use the correct version for these scripts. On some systems, both Python 2.x and 3.x are installed. It is possible that the normal invocation of python starts up Python 2.x, and that to start up Python 3.x requires invoking with python3 or python3.4 etc. You can test the version by python –version or python3 –version. If this is so, replace any usage of 'python' in the examples below with the appropriate invocation.
  • The make.py used in construction of the addons requires that the LANGUAGE environment variable be set to 'en_US.UTF-8'.
  • The make.py used in construction of the addons requires that the GRAMPSPATH environment variable be set to your path to the Gramps source tree.
  • intltool must be installed;
sudo apt-get install intltool

For example if your home directory is '/home/name' and you use the suggested path names, use

GRAMPSPATH=/home/name/gramps LANGUAGE='en_US.UTF-8' python3 make.py ...

to replace the ./make.py in the examples below.

Package your addon

To create a downloadable package:

./make.py gramps60 build NewProjectName or
./make.py gramps52 build NewProjectName for the older 5.2 branch.

Addons should not be created on the master branch.

Gramps-notes.png
Note:

Running the command make.py xxx build will increment the third number in your dotted version number of all addons in the *.gpr.py file. Consider this number to be a "build number".

This will leave your 'addons-source' with untracked changes according to git. The updated 'NewProjectName/NewProjectName.gpr.py ' is ready to add and commit.

Commit the updated gpr.py 

 cd addons-source
 git add gramps60/download/NewProjectName.gpr.py
 git commit -m "Updated new plugin gpr: NewProjectName"

Commit the updated compressed tar file: 

 cd ../addons
 git add gramps60/download/NewProjectName.addon.tgz
 git commit -m "Added new plugin: NewProjectName"

List your addon in the Gramps Plugin Manager

Gnome-important.png
Gramps needs to have been built

Make sure you have already built gramps60 or master. Change to the appropriate git branch in your gramps directory, and run python3 setup.py build See Linux:Build_from_source

To create a listing:

cd '~/gramps-addons' or wherever you have built your addon
GRAMPSPATH=path/to/your/gramps/install ./make.py gramps60 listing NewProjectName


That will create a series of files in the ../listings/ directory.

Then commit the updated listing to GitHub: 

 cd addons
 git add gramps60/listings/*
 git commit -m "Added new plugin to listings: NewProjectName"


Commands to compile translations using make.py

You need the gramps.pot file that is currently being used for the Weblate translations in your local gramps 6.0 tree. It is used to exclude strings from the Addons translation component that have already been translated in the core Program component. This is:

https://github.com/gramps-project/gramps/blob/maintenance/gramps60/po/gramps.pot


Translation workflow with make.py:

  1. Run the command init to add any new strings to the template.pot file.
  2. The command aggregate-pot is run to aggregate all the addon template.pot files into a single po/addons.pot file which is then used by Weblate for translations. Note: The GRAMPSPATH environment variable must be set to a current gramps60 repository for this step. If run with no updates in any template.pot, the resulting addons.pot file will only have a timestamp update. In this case, it does not need merged back.

The Weblate translators can now translate the strings. Weblate generates a pull request. This can be merged on a regular basis. You can do this from the GitHub GUI, but don’t squash the commits.

The local.po files (which were updated by Weblate) are updated for publishing using the extract-po command. These updates should be merged back to the gramps60 branch.

At this point, the translations are committed but not published. Since publishing updates every addon, the timing for this action is TBD.

Example use of make.py

  • If you run the aggregate-pot command without any recent commits, the only change is to the POT-Creation-Date line.
  • As a test, if you change a single string in the AllNamesQuickview addon and then run init, you see the change and also the string at line 5 in the source code gets moved. Then if you run aggregate-pot you see the modified string and a moved string. This shouldn’t cause a problem.


Pre-6.0 only

Tango-Dialog-information.png
From Gramps 6.x translations can be done on Weblate. Initial testing has appeared successful, but please let us know if you notice any problems. The Weblate Addons component contains aggregated translations for every addon.

https://hosted.weblate.org/projects/gramps-project/addons/


Get translators to translate your addon into multiple languages

If you designed for localization, the addon will begin supporting a single language. Make your addon inviting for volunteers to translate it into their native language.

  • Initialize and update the template.pot for your addon:
cd ~/addons-source
./make.py gramps52 init NewProjectName
  • You should edit the header of template.pot with your information, so it gets copied to individual language files.
  • Initialize a language for your addon (say French, fr):
./make.py gramps52 init NewProjectName fr
  • Update it from gramps and other addons:
./make.py gramps52 update NewProjectName fr
  • Edit the translations file manually:
/NewProjectName/po/fr-local.po
  • Compile the language:
./make.py gramps5 compile NewProjectName
  • Add or update your local language file, and commit changes:
