scrawl

scrawl is the Subverge text editor. It is opened by one of:

'top open           the root unit that defines top
'sq edit            a definition in this tab
"mine" unit         a new root unit

Keys

Key
arrows, Home, End, Page Up, Page Down	move
Ctrl-T, Ctrl-B	top, bottom
Ctrl-F	find, and Enter on an empty search repeats it
Ctrl-K	cut the line
Ctrl-U	paste it above the cursor
Ctrl-S	save
Ctrl-Q	quit, twice if there are unsaved changes
Tab	spaces to the next multiple of 4

scrawl has no undo and no selection, and the clipboard holds a single line.

Saving and quitting

Ctrl-S saves the text, and the rebuild happens on quit, using the last saved version. Quitting without saving changes nothing. A root unit rebuilds all or nothing (root), and the result is saved to disk.

edit

'name edit opens the body of a definition without its outer brackets, and redefines name in your tab on quit. As a result:

'newname edit on an undefined name creates a new word, which is convenient for longer definitions.
'top edit on a root word creates a private copy in your tab. Use open to change root itself.
If the text doesn't parse, it is kept as a string and scrawl reports that didn't parse with the reason. The word then pushes that string until it is edited and fixed.
