Components

I can think of a lot of potentially useful, pluggable components. The following is a brain dump of the types of components I can imagine. Some of them may not need their own types, but can share types with other components.

- Translator from raw input bytes to high level events. If we integrate with a specific terminal, we can receive high level events directly, allowing us to handle, for example, touchpad gestures.
- Dispatcher: Translate events into directives, I.E. what to do. This component can handle key bindings.
- Buffer: Translates directives that operate on text into new text.
- Compiler: Translates a text buffer into Ok(AST) or Err(Error).
- Stage: A -> Result (could implement lexing, parsing, or rest of the compiler)
- Executor: Executes an AST.
- Completor: Returns completions for a partial buffer
- Historian: Given an executed command, and a result, adds a history entry.
- Suggestor: Given a partial buffer, gives suggestions. (Like flags, as opposed to full completions of the buffer)
- Prompter: Draws the prompt.
- Optimizer: Given a program, produces a modified or better program.
- Analyzer: Given a program, catches errors with that program statically. Might also produce an output program which is better typed.
- Helper: Given a buffer, produce help about that buffer. (About command, args, probably)
- Multiplexer: Handle multiplexing input between multiple shells. (Like tmux.)
- Searcher: Handles finding binaries in your path.
- Renderer: Turns markup into styled text.

L’issue est un brainstorming sur de possibles composants du shell, notamment des traducteurs, des répartiteurs, des tampons, des compilateurs, des exécuteurs et des moteurs de rendu, mais elle ne nomme aucun fichier, test ou point d’entrée. Commencez par limiter la proposition à un composant précis et définissez ses interfaces ainsi que ses critères d’acceptation ; le travail sera terminé lorsque ce composant délimité et son comportement attendu seront clairement spécifiés.
