GUI Todo Now

Non-GUI Todo Now

• Redesign case icon to avoid non-locality.
• Move @ pattern circles so that they are on the same side as the variables.
• Add command line flags for color style, embedding, and whether to draw arrowheads.
• Add wiki pages discussing: Why a visual language?, History of Glance, How to contribute, Code guide [code style, ...], etc..

GUI Todo Later

• Connect nodes with lines
• Display the undo state in the app Bug #14
• Scale based on mouse position
• Extract out GUI interface code (GTK and GDK) into a module.
• Refactor to make code extensible (e.g. records of functions instead of enums)
• Click a button that shows an image of the mouse and keyboard controls in a new window.

Testing todos

• Fix the arrowheads being too big for SyntaxGraph drawings.

Visual todos

• Use different line styles (e.g. dashed, solid, wavy) in addition to colors

• Consider improving nested apply icons embedded in case/guard icons.

• Let lines connect to ports other than the original source

• Use diagrams to shrink the drawing until icons start overlapping.

• Make an icon font/library with labeled ports. E.g. the apply icon would have text labels "function", "result", "arg 0", "arg 1", etc.

Translate todos

• Fix applyComposeScore in Translate.hs not counting expressions that nest via reference. May need to move compose generation to after translate.

• Add proper RecConstr, and RecUpdate support.

• Special case for otherwise.

Command line todos

• Tab completion
