Describe the question

Hi,
I'm reaching out for people willing to support me in writing a native previewer plugin for JWT files. Nats server and account configuration is stored in such a format and when navigating through hundreds of JWT files in a file structure for a cluster, it would be nice to have native preview support in Yazi (with code highlighting of the resulting JSON content inside the payload).
Many thanks in advance.

Anything else?

Hi! @smangels Mostly any yazi "previewers" are based on "cli" tools that show (only) the preview for it in the terminal. Many JWT CLI's I have seen also allow editing and other functionalities, than just a good preview.
If you know of something of a JWT previewer, I can make it for you.
Or
If you are developing a new tool itself, I would like to help out(if possible).

Hi, I've managed to get it up an running decoding the JWT through a CLI tool and are happy to share the code with you. It would be even better if we could get it decode natively in Lua. But I've struggled to get a development environment up and running. Did you manage Anirudh? /Sebastian BR, Re:

We need not convert it to a Lua code, if the CLI can be installed, and can just preview nicely, then it should be enough in that language itself.
Can you share the repo? And a screenshot of the preview of how it looks?

Yazi has a ya.json_decode() function, here's an example:

yazi/yazi-plugin/preset/plugins/video.lua

Lines 115 to 121 in 63eb82a

    
           local output, err = 
        
           	Command("ffprobe"):args({ "-v", "quiet", "-show_entries", entries, "-of", "json=c=1", tostring(url) }):output() 
        
           if not output then 
        
           	return nil, Err("Failed to start `ffprobe`, error: " .. err) 
        
           end 
        
           local t = ya.json_decode(output.stdout)

The repository can be found at https://github.com/smangels/jwt.yazi and it contains a test.jwt file. The issue is that we are using our own JWT decoder binary and my gut feeling tells me that it would be much cleaner to simply implement the decoder feature in plain Lua instead of relying on an external tool - shouldn't be too complicated. https://gist.github.com/inaiat/02bf5d11732d8e4d7b7546399a3a49af What do you think?

Yeah it would be great, you can add this in your init.lua and call the function.
I feel its better if the plugin doesnt have external dependency if it can be implemented within init.lua itself.

What I meant was rather decoding JWT natively in Lua. Instead of having to rely on external CLI tool. BR, Re:

Yeah I agree. Do you know how to make the Lua environment aware of that there the Yazi Lua library somewhere in users file structure? I'm using Neovim. BR, Re:

I'll have a look into it. Could be the process of splitting up header, body and signature? Or maybe the fact that padding is applied when length is uneven? BR, Re:
