Editor

An editor inspired by acme.

Design

• Editor server (./editor/...)
  • go implementation with the executable editor(.exe)
  • serves the front-end
  • handles editor requests on complete window content
  • executes commands or handles built-ins
  • does not follow the state of windows or their layout
• Front-end: (./editor/html/...)
  • mainly javascript served by the editor server on initial requests.
  • does the layout of windows
  • uses codemirror library for the actual editing
• Editor commands (./cmd/...)
  • each editor command is an executable program and may be written in any language
  • is has to follow the protocol (./editor/cmd/cmd.go: Cmd) encoded in json.
  • new commands can be added or replaced, which does not require changes to the server or front-end
  • even read or write are their own commands

Compared to acme

• runs on windows, uses the browser as frontend
• supports images and html
• their is no file system access to the editor state
• current state and layout is only known to the front-end
• lacks the top row, windows are added by pulling down the top window and columns are added by moving a window to the right by more than 50%

editor's Issues

implement findNext with right button

in static/editor.js:

 this.editor.on('mousedown', function(cm, evt) {
                if (evt.button == 2) {
                        var s = cm.getSelection()
                        var c = cm.getSearchCursor(s, cm.getCursor())
                        if (c.findNext()) {
                                cm.setSelection(c.pos.from, c.pos.to)
                                evt.preventDefault()
                                return
                        }
                        // Start from top.
                        c = cm.getSearchCursor(s)
                        if (c.findNext()) {
                                cm.setSelection(c.pos.from, c.pos.to)
                                evt.preventDefault()
                        }
                }
        })
