So this is related to #9 since it will be useful for formatting git infos. Objectives:

• Provide a way to customize prompt
• Replace classic, modern and arrow with a corresponding theme file

Implementation idea: So first of all i had the idea of using a runtime formatting library such as mustache but it would cause problem for text coloring since these formater just replace and not color anything. So we have to implement our parser to do some token recognition. For that there is a library nom well known for parsing byte data and also string. With that in mind i had to think about a theme file syntax. Here is an example i had in mind:

&[#FF00FF]`[`{{home_dir}}`]`&[#00FF00]{{user_input}}

So

• &[#FF00FF] tells to color the next string with the corresponding hex color. Everything will have this color until the next &[#00FF00]
• [ is a string literal so it would be display as [
• {{home}} is for variable it would be replace with the correct value (for example ~/Documents/vsh). There could be a lot of different variable like time, hostname, user, return code of previous program...

Anyway here is the current roadmap:

• [x] Implement a parser
• [x] Color & replace variables
• [x] Load theme from config file
• [x] Flexibility for variables / large choice + documentation
• [x] Background color
• [x] Text style (bold italic etc)
• [x] Allow new line to be added outside string literal
• [x] Error handling
• [ ] Non truecolor support
• [ ] Replace current theme with a theme string using the parser

I implemented parsing of any size commands, including using exec as a prefix. I also implemented it in a way that makes it easy to add asynchronous commands (ones that are called ending in "&"): all that has to be done is send them to another thread to be called. I improved install.py by requiring a correct answer instead of simply repeating it, and I implemented a way to preview the releases in the installer, as well as providing a way of installing a default configuration file. Finally, I improved error reporting and fixed crashes in the commands.

Hi there. This looks like a really neat project! I would even consider using it instead of ZSH once piping and the scripting language features are fully implemented 😄

Even though there isn't any of that yet, I don't see a way for me to run a external command such as Starship as my prompt. Would this be possible to implement?

I did a few edits for stability, mostly just to prevent crashing. I also implemented expanding ("~/Downloads" becomes "$HOME/Downloads") in path names, which can be escaped.

Remove a lot of the excess HTML in the README and add license to the README.

The HTML renders differently on different platforms and doesn't look proper now.

What i want to implement:

• [x] Current branch and files modified
• [x] Optionally see how many lines were added/deleted
• [ ] Customization of how everything is visualized (colors, position) using .vshrc.toml (might require a run time formatting library such as runtime-fmt)
• [ ] Auto complete on git commands

Some observation regarding this pr:

• It introduces a lot of new dependency and some of these are quite heavy (openssl) so may be the choice of git2 is not the best idea. I made this choice because it's quite popular and has every functionality of git.
• Storing and recreating an instance on every prompt is not ideal, i'm currently looking for a better implementation, if you have any suggestion, please do a suggestion.
• It might be a good idea to implement git as a plugin
