GraphWiz Dot Viewer

A GTK based viewer for dot files. Adapted from xdot.py by Jose Fonseca.

Features from xdot

• Pan and Zoom
• Center on node
• Follow edges
• Automatic refresh when file changed

N.B.: URL links have been removed to accommodate other features.

Features added

• Node regex search
• Side panel showing contents of nodes
• Better refresh support using inotify

TODO

• use GIO for IO and for file watches
• Complete rewrite of parser reusing pygraphviz
• Advanced open:
  • Open dot file
  • Open xdot file
  • Filter to be used
  • Get from command: this would prompt for a command to execute to generate the graph to be displayed. Refresh will re-run the command. Save would always prompt for a location and dump the generated dot.
• Modes:
  • View: the current one. Allows for exploration, search.
  • Edit: would allow to modify the model (attributes) on the fly, saving the modifications to file.
• Options:
  • watch = auto reload on changes (cannot be switched off at the moment)
  • GraphViz filter to use (maybe put this as a combo in toolbar)
  • names of extra attributes to show + defaults
  • enable/disable animations
  • colors/style of highlights
• Embedded text editor for source (with jump-to-line?)
• Status OSD: loading/layout/reloading/error...
• Stop/kill button
• Search options (search bar?): regex, fields ...
• Update animation: delete/add/move identifying nodes by id (not very reliable but can be useful)
• General overlay mechanism for annotations: url/extra-contents/flags
• Pressing CTRL shows if node has url, ctrl+click jumps to url
• keys to highlight topological features: successors/predecessors...
• Advanced side pane with content parsing:
  • booleans (flags)
  • markdown
  • HTML
  • plain text
  • JSON
  • Filenames (xdg-open/preview for plain-text and pictures)
  • nested dot graphs (?)
• Double click triggers the default action on default extra attrib (contents?)
• Attributes in side pane
• Ability to modify attributes from side pane and save to file (?)
