bagel_gui

Bagel (Biologically inspired Graph-Based Language) is a cross-platform graph-based dataflow language developed at the Robotics Innovation Center of the German Research Center for Artificial Intelligence (DFKI-RIC) and the University of Bremen. It runs on (Ubuntu) Linux, Mac and Windows.

This package provides a graph GUI to visualize and edit Bagel graphs. The software is developed in a more generic fashion allowing to extend/use it for other graph models as well.

General {#general}

The main user documentation of Bagel can be found at: https://github.com/dfki-ric/bagel_wiki/wiki

The API documentation of osg_graph_viz can be build in the doc sub-folder with the make command. The documentation is build into the doc/build folder.

Install

Either see: https://git.hb.dfki.de/team-learning/package_definitions

or ROCK users can simply import the bagel/package_set and execute autoproj build bagel/gui

Configuration

The bagel gui is more or less a generic graph gui and needs the following configuration file:

• libs.txt: Used by the generic gui_app to load the bagel_gui possible configuration:

cfg_manager_gui
bagel_gui

• node_config.yml: Used to define the path to extern nodes and to load the possible node definitions for the graph. possible configuration:

extern_nodes_path: "/install/share/bagel/master/extern_nodes/"
nodes:
  - name: input
    type: INPUT
    outputs: [name: out1]
  - name: pipe
    type: PIPE
    inputs: [name: in1, name: in2]
    outputs: [name: out1, name: out2]
  - name: output
    type: OUTPUT
    inputs: [name: in1]

Execute

To execute the gui start the gui_app within the configuration folder where the two configuration files are located.

The bagel gui installs a configuration for editing bagel graph into:

install/configuration/bagel_gui

Todo:

• history causes creation of a port in description node which causes error during save
• orthogonal edges are loaded incorrect (sometimes)
• decoupling edges sometimes produces a visible left over of old edge
• change edge types
• move node while creating new edge
• keep orthogonal edges correct while moving nodes
• fold icon
• median merge icon
• handle port names correctly (no edit of port node names)
• error console
• open subgraph in new tab when double clicking on subgraph
• handle extern nodes from different bagel_control branches -> relative paths
• history: save entry when node or edge is deleted
• selcedtedEdges/selecedNodes is not correct (except when using a frame)
