4th coding sprint

Definition and creation of the openalea package. This package contains a script create_config.py which create a config file. Here is an instance of a config.py generated.

namespace= 'openalea'
version= '0.0.2'
prefix_dir= r'/usr/local/openalea'
lib_dir= r'/usr/local/openalea/lib'
include_dir= r'/usr/local/openalea/include'
bin_dir= r'/usr/local/openalea/bin'
 
doc_dir=r'/usr/local/openalea/doc'
test_dir=r'/usr/local/openalea/test'
setting_dir=r'/usr/local/openalea'

This script will be use by other package installer in order to know where to install shared library and others files.

3nd coding sprint

  • Samuel Dufour-Kowalski

Template package

Preparation for the integration of the Pydrop package.

2nd coding sprint

Date: 08/03/06 - 10/03/06

Authors:

  • Florence Chaubert,
  • Nicolas Donès,
  • Christophe Pradal,
  • Colin Smith,
  • Frédéric Théveny

Summary of Concepts

  • Package
    • Node factories
    • Widget factories
    • Description of the contents
  • Package Manager
    • Allows the loading and registration of packages
    • Supplies the list of available packages
  • Node
    • Callable object
    • Defined, typed inputs and outputs
  • Widgets
    • Graphic representation of a node
  • Application
    • A collection of widgets
  • Workflow
    • Directed acyclic (this may change in the future) graph of nodes with entry and exit points
    • A workflow can have several entry and exit points
    • The state of each node is saved in the workflow

Package Installation Process

Main issue: We need a tranformation stage to take a package from its distribution form to a form that is compiled and can be copied into the OpenALEA package pool.

A package should copy its files into OpenALEA at the following locations (assuming a root directory of ALEA).

libraries

  ALEA/lib 

excutables

  ALEA/bin 

include files

  ALEA/include/pkgname 

python files

  ALEA/package/pkgname 

documentation

  ALEA/doc/pkgname 

resource files

  ALEA/rsc/pkgname 

a usage example

  ALEA/example/pkgname 

package tests

  ALEA/test/pkgname 

It is the responsibility of the package developer to put the outputs of the package compilation in the correct intermediary places such that they can be copied into OpenALEA by the function package.install.

By convention the intermediary organisation should be (assuming a root directory of PKG, usually the package name)

libraries

  PKG/lib 

excutables

  PKG/bin 

include files

  PKG/include 

python files

  PKG/src 

documentation

  PKG/doc 

resource files

  PKG/rsc 

a usage example

  PKG/example 

package tests

  PKG/test

      • the Package Manager interface
      • the python shell
  • Package & Package Manager
    • Finish the package installation code
      • Need to get the installation tests working
    • Verfication of the dependencies
  • OpenALEA Configuration

  • Pierre Barbier de Reuille,
  • Loïc Calvino,
  • David DaSilva,
  • Nicolas Donès,
  • Christophe Pradal,
  • Szymon Stoma,
  • Frédéric Théveny

Concepts

GUI

Python Interpreter

  1. PyCute (should be changed)

Workspaces (visual programming)

  • Canvas + CanvasItems
    1. Connection between CanvasItems
    2. Link deletion
    3. CanvasItems movement capability

Software Bus

  • Packages (menu)
    1. Name, Short description, System name, Visible Status
  • Node (only for visible packages)
    1. package sorting (Name, Short description, System name, Long Description, Loaded status, Installation status)
    2. category sorting (2 levels ?)
  • Object
  1. Name and type of instanciated objects
  • Applications (only for visible packages)
  1. ?

Applications

  • A Separated windows per application
  • Communication via software bus (drag & drop)

KERNEL

Workflow

  1. Node network (DAG)
  2. Communication between nodes
  3. Workflow evaluation (semi-lazy)

Package Manager

  1. Available Package list
  2. Registration process
  3. Installation process
  4. Depedencies management

Package

  1. Legal informations, Name, System name, Short and Long description, Version
  2. Directories
  3. Available Nodes
  4. Available Widgets
  5. Available Applications

Node

  1. Legal informations, Name, System name, Short and Long description, Version
  2. Typed Inputs and Outputs
  3. Callable object
  4. Subset of Inputs for the GUI –> parameters

ROADMAP

- Cross review and integration - Some packages - Having a 'import alea' working with packages from regular interpretor - Simple scenario - Documentation

GUI

  1. Finish nodes visualization
  2. Create objects visualization
  3. Create applications visualization
  4. Continue the workspace
  5. Interaction between differents parts (drag and drop)

—→ Problem PyQt3 does not exist on Windows, PyQt4 coming ?

Kernel

  1. Finish Package Manager implementation
    • Stable API
    • Installation process
    • Dependencies management
  2. Settings implementation
  3. Signaling system
  4. Data Store implementation

Workflow

  1. Finish and improve lazy evaluation implementation
  2. Integration with main window –> API
  3. Node definition and API
  4. Type system

The next coding Sprint should take place in beginning 2006 and before we should :

  • Finish the kernel Package Manager and Data Store parts without signal system
  • Console mode Integration and scenario definition
