Programs

Comun Shell

• global stack modified by scripts that are run and commands in the shell?
• global "program" to which we append commands?

Text Editor

• name: fe? (file editor), fed?
• will be both text editor AND hex editor (will be able to switch between text and hex view)
• similar to vim but simpler
• will work without color, non-ASCII symbols and animations (all can be optional)
• cursor: ^ under the char? < after it? |?
• tabs? splits?
• should cursor always be in the middle of the screen? would be KISS
• modes (switched with escape?):
  • typing:
  • command: typing simple commands (think about syntax), possibilities:
  • w filename (write/save)
  • f what (find, allowing "almost regex" search)
  • u (undo)
  • r (redo)
  • s what what (substitute, some kinda "almost regex")
  • o (open)
  • c (copy)
  • p (paste)
  • x (cut)
  • n (new)
  • q (quit)
  • m (mode, switch between text and hex view)
