# dedlin
Dedlin is an interactive line-by-line text editor and a DSL, similar to edlin or ed. It is perfect for
letting AI chatbots edit documents without sending the whole document back and forth.
It is scriptable making it similar to `sed` for doing find, insert, replace, delete operations on existing files.
Soon it will support non-line number ranges, e.g. `"/Done/ DELETE`
Dedlin extends on [edlin](https://en.wikipedia.org/wiki/Edlin) enough that it is not backwards compatible.
I have made changes to make the app less user hostile than classic ed or edlin, 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.
```bash
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.
```powershell
# 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`
```bash
dedlin file_name.txt
```
Command line help
```text
> python -m dedlin --help
