Structure of the the jamovi sources

The jamovi source structure contains the following components:

directory

contents

build command

artifacts

electron/

the electron app which represents the entry point of the program

npm install

default, app.asar

server/

the server code written in python and built on top of tornado

python3 setup.py build_ext --inplace

jamovi-server (python module)

engine/

the background processing engine (written in C++, making use of R)

make

jamovi-engine (an executable)

client/

the html, javascript and css (make up the user interface for jamovi)

npm install

js, css, html

examples/

the example data sets

(these can be copied verbatim)

platform/

platform specific files (icons, etc.)

The electron/, server/, engine/ and client/ subprojects can be built by navigating into their directories and issuing the build command listed in the table above.

Final structure

After building each of these subprojects, the results of the builds are assembled into a final tree for installation. the final jamovi folder structure for Ubuntu is as follows:

/usr/lib/jamovi/
├── bin/
|   ├── locales/
|   |   └── ...
|   ├── resources/
|   |   ├── electron.asar
|   |   └── default_app.asar
|   ├── jamovi
|   ├── env.conf
|   └── ...
└── Resources
    ├── jamovi
    │   ├── client/
    |   |   └── assets/
    |   |   |   └── ...
    |   |   └── ...
    |   ├── examples/
    |   |   └── ...
    |   └── server/
    |       └── jamovi/server/
    └── modules
        ├── base
        |   └── R/
        |       └── ...
        └── jmv/
            └── ...

bin/

The electron executable is the entry point for jamovi. it represents a combined web browser interface and nodejs interpreter. In constructing the bin/ folder, its contents are simply taken from electron release archives (available from https://electron.atom.io), with three exceptions:

  • the jamovi executable

  • resources/default_app.asar

  • env.conf

The jamovi executable is simply the electron executable renamed.

The resources/default_app.asar is the default electron app which electron goes looking for when it starts up. This needs to be replaced with the default_app.asar produced by the electron component of jamovi (from the electron/ folder in the repo).

env.conf contains the path settings and environmental variables that jamovi requires. variables which end in PATH or HOME are resolved relative to the env.conf. On Ubuntu, it’s contents are:

[ENV]

R_HOME=/usr/lib/R
R_LIBS=/usr/lib/R/site-library:/usr/lib/R/library
PYTHONPATH=../Resources/jamovi/server

JAMOVI_HOME=..
JAMOVI_MODULES_PATH=../Resources/modules
JAMOVI_EXAMPLES_PATH=../Resources/jamovi/examples
JAMOVI_CLIENT_PATH=../Resources/jamovi/client
JAMOVI_SERVER_CMD=/usr/bin/python3 -u -m jamovi.server 0

Resources/jamovi/client

This folder contains the following files from the client/ subproject:

index.html
main.js
main.css
analysisui.html
analysisui.js
analysisui.css
resultsview.html
resultsview.js
resultsview.css
assets/*

Resources/jamovi/server

This folder should contain the following files and folders from the server subproject:

jamovi/server/
jamovi/core.*.so
jamovi/__init__.py
jamovi/__pycache__

Note that the PYTHONPATH in env.conf is Resources/jamovi/server, so the final path of the jamovi/server/ directory will look a bit silly:

Resources/jamovi/server/jamovi/server

Resources/jamovi/examples

This is just the contents from the examples/ subfolder
