Hi, all!
Readline is pure go library that provides line-editing and history capability for interactive users with a command-line interface. It works well in OSX/Linux/Windows.
It supports:
This is very neat, although I’ve yet to look at the full details. 
There are a few similar things out there, but most were lacking in one way or another when I was last trying to use one to build an interactive-shell like experience. For the record, the things that annoyed me then was getting the combination of:
Customizable history. I.e. some commands I may not want to add to history, duplicates are sometimes useful sometimes not, etc so this really needs to be handled by the application and not decided fully by the readline package.
Customizable word for word tab completion. I needed to be able to support completing commands with subcommands, so not just a “line” but word for word. Ideally with placeholder support, although this can be handled by the application if the completer gets to see all keystrokes. x/crypto/ssh/terminal gets this mostly right.
Looks very thorough.
I’ve been using https://github.com/peterh/liner which is a similar library - how would you say they differ?
Thanks
Nick
@ncw
liner and readline are both have the same goal, and they are almost provide the same features.
If I have to say the differents between them:
liner is more like bash and readline's is zsh.readline have a better UI/UE of tab-completionreadline supports vi modeliner has more compatibility and stability than readline. readline is just a 10-days-old repo. It has a long way to go and needs anyone’s help.
Thanks for the explanation. I’ll try it out!
