Flyline

A modern readline alternative for bash.

Features:

• Undo and redo support
• Cursor animations
• Fuzzy history suggestions
• Fuzzy autocompletions
• Integration with bash autocomplete
• Mouse support:
  • Click to move cursor in buffer
  • Hover over command for tooltips
• Tab completions when writing subshells, command substitutions, process substitutions
• Tab completions for aliases (e.g. if gc aliases to git commit, gc --verbo<TAB> works as expected )

Installation

Download the latest libflyline.so. In your .bashrc (or in your current bash session): enable -f /path/to/libflyline.so flyline.

Integrations

VsCode:

• I'd recommend setting terminal.integrated.minimumContrastRatio = 1 to prevent the cell's foreground colour changing it's under the cursor.
• You may want to set terminal.integrated.macOptionIsMeta so Option+key shortcuts are properly recognised.
• Shell integration WIP

MacOs

Command+<KEY> shortcuts are often captured by the terminal emulator and not forwarded to the shell. Two fixes are:

• Map Command+<KEY> toControl+<KEY> in your termianl emulator settings.
• Use a terminal emulator that supports Kitty's exteneded keyboard protocol. This allows flyline to receive Command+<KEY> events.
