pokeget is not a clone of pokemon-colorscripts, nor was inspired by it in the first place.
The true main difference is that pokemon-colorscripts gets its sprites from a folder stored locally while pokeget get's its sprites from the pokeget github repo. This allows pokeget's sprites to be renamed, fixed, redone, and tweaked without any update necessary from the user. Due to this functionality, pokeget is slower by a factor of 5x.
pokemon-colorscripts has been tested on macOS though, and while pokeget-lite could work theoretically on macOS it has not been tested.
When I googled about similar tools while I was developing the first version of pokeget I found pokemon-colorscripts and even used it as a source for a while. But I continued developing pokeget because I generally had some issues with it and I thought it could be improved.
pokemon-colorscripts has issues with its sprites with some of them appearing blurry, as well as a lack of some other features. pokeget has already achieved feature parity with pokemon-colorscripts, and generally has more features.
pokemon-colorscripts is still a really cool program, but pokeget does fix some of its issues.
pokeshell is another extremely cool project created by acxz.
As listed in pokeshell's page, it has a lot more features than pokeget, because it's functionally different.
pokeget fetches pre-converted sprites, which were converted with a python script, and displays them using a Unicode symbol and terminal colors.
pokeshell fetches normal png/gif files and converts them client-side with a program called timg.
This offers a lot more flexibility with what you can do with the images, such as displaying animated sprites and resizing to the terminal. pokeshell also makes use of another program called imagemagick to further edit images to display multiple pokemon at once.
These two tools allow a lot of image manipulation to be done super easily, which explains the features. The downside to this is that it is slower (~1.6x).
This also adds a need for extra dependencies, and pokeshell also gets its pokemon sprites from external sources, while pokeget sticks to it's own repo.
pokeget is also much more portable, and on many distro's works completely out of the box. One of pokeget's main goals is to have as little dependencies as it can without compromising code quality.
pokeshell is compatible with macOS, while pokeget isn't fully compatible.
Unlike pokemon-colorscripts which doesn't have that many benefits over pokeget, pokeshell does have some benefits. You can see here for a feature comparison in tabular form.
Also pokeshell has shell autocompletion, and pokeget doesn't.
If you want to have a program which is more feature rich, then pokeshell is better. If you want something simple, fast, and low on dependencies, use pokeget.
Or better yet just use both.
I highly recommend you check out pokeshell.
Make sure to star, watch, and fork both projects ;)
