Show HN: Replbuilder, quickly build a Python REPL CLI prompt

• replbuilder

  7 149 3.4 Python

  Python helper tool for building and running a repl with custom commands

• python-prompt-toolkit

  21 8,948 7.8 Python

  Library for building powerful interactive command line applications in Python

  

> The purpose is not to do this however, the goal for a repl cli is usually to invoke a set of particular, already implemented commands, not on the fly python input and output. The implementation will be predefined and packaged, repl are only used to run a list of specific commands with arguments that implementation has already defined.

That's a very strange definition for a REPL, I would just call that an (interactive) CLI. Maybe that's why you couldn't find anything when you were doing your search? I used python-prompt-toolkit [0] when building such interfaces. pgcli [1] is an example of such an interface built with prompt-toolkit.

It has a lot of nice autocomplete and readline emulation options. Maybe it's something you can integrate with your project.

• click-repl

  1 215 5.3 Python

  Subcommand REPL for click apps

  

Great job! Heres a similar tool but for the Click command line toolkit instead of argparse:

(Also should work with Typer and other libraries wrapping Click)

• CPython

  1,314 59,531 10.0 Python

  The Python programming language

  

Interesting! You can also inherit from code.InteractiveConsole[0] to build a REPL. That's how the new sqlite3 REPL is implemented[1]

• command-line-api

  22 3,304 7.8 C#

  Command line parsing, invocation, and rendering of terminal output.

  

This looks really nice.

I've been spending a lot of time with python lately because of new project work, I had never really used python before. It's been really cool to keep finding stuff like this.

The equivalent of something like in the .net world (eg https://github.com/dotnet/command-line-api) and even powershell modules (https://learn.microsoft.com/en-us/powershell/module/microsof...) have a steeper learning curve and take significantly MORE work to set up for the end-user.
