dedlin 1.13.0

Line editor, edlin clone with many improvements

dedlin

Dedlin is an interactive line-by-line text editor and a DSL. Line editors suck, but they are easy to write and the DSL is mildly interesting.

While this is a clone of edlin, this is not intended to be backwards compatible with anything. I have made changes to make the app less user hostile, but there is a --vim_mode where all help, warnings, feedback will be suppressed.

Installation

Requires python 3.11 or higher. Someday I'll write a standalone installer for it.

Install globally in an isolated virtual environment. This is a good idea.

pipx install dedlin

Run pre-built image with docker. Painful, but you're using an edlin clone, so that is what you're looking for.

# This is should work in powershell or linux bash. Not windows git-bash.
docker run --rm -it -v "${PWD}/:/app"  ghcr.io/matthewdeanmartin/dedlin:latest file.txt

Usage

Launch and edit file_name.txt

If you installed with pip or pipx

dedlin file_name.txt
