ncsh

An interactive unix shell focused on speed and building everything from scratch.

features

• Autocompletions as you type: autocompletions based on history and weight.
• Tab autocompletions: view all available options by pressing tab and cycle through them with up/down keys and select with enter.
• History: command history tracked and can be cycled through using up/down keys.
• Manipulate input: home, end, CTRL+W to delete a word, CTRL+U to delete a line, etc.

installation notes

• sudo make install ONLY calls the install command to add the ELF executable to /usr/local.
• Install directory is by default /usr/local.
• Pass in DESTDIR if you want to install it somewhere else.
• History file .ncsh_history tries to use XDG_CONFIG_HOME if available, or else HOME.

goals

• rc file and more configurations
• more compile-time configurations
• aliasing
• frecency-based autocomplete
• support removing entries from history and autocompletions (use sqlite??)
• move built-in commands like export, kill, setting environment variables, etc.
• aliasing for user-defined commands, user configuration
• better prompt line and configurable prompt line
• support scripts through a non-iteractive mode
• build for and test on mac (I don't have one)
• build for and test on windows with msys2
• math
