[ianthomas23]

The basic framework is up and running. Here is an overview of the required functionality, to be updated with progress:

Command-line parsing/handling

• Editing e.g. backspace to delete previous character
• Tab completion of command and file names
• History
• Pasting into terminal
• Prompts
• Globbing
• Virtual directories . and ..
• Quote handling
• Expanding env vars
• Combining multiple commands using ;, && etc

Filesystem

• Access to JupyterLite file system in a pluggable way, currently Contents.IManager but could change in future. Async.

Input/Output

• Output to file and terminal
• Terminal may optionally support color escape codes
• Terminal output can vary according to number of columns e.g. ls
• Stdin e.g. wc
• Pipes
• Redirection e.g. 2>&1
• Discard output to /dev/null?
• Passing keystrokes to some commands (e.g. less) whilst command is running

Command handling

• Declaring command options that are handled in a generic way
• Expanding options so that ls -al is the same as ls -a -l
• Help (man) info auto generated from declared options
• Exit codes

• alias
• cat
• clear
• cp
• cd
• echo
• env

• grep
• head
• history
• less
• ls
