# Contribution Guide
|
|
|
|
First of all, thank you for contributing! :3
|
|
|
|
To ensure your contribution is robust, please follow the below guide!
|
|
|
|
## Style Guide
|
|
|
|
- This project has a very minimal .editorconfig. Make sure your editor supports this!
|
|
If you are using VSCode, it should automatically recommend you the extension; If not,
|
|
please install the Editorconfig extension
|
|
- Try to follow the formatting in the rest of the project and stay consistent
|
|
- Follow the file naming convention. File names should usually be camelCase, unless they export a Class
|
|
or React Component, in which case they should be PascalCase
|
|
|
|
|
|
## Contributing a Plugin
|
|
|
|
Because plugins modify code directly, incompatibilities are a problem.
|
|
|
|
Thus, 3rd party plugins are not supported, instead all plugins are part of Vencord itself.
|
|
This way we can ensure compatibility and high quality patches.
|
|
|
|
Follow the below guide to make your first plugin!
|
|
|
|
|
|
### Finding the right module to patch
|
|
|
|
If the thing you want to patch is an action performed when interacting with a part of the UI, use React DevTools.
|
|
They come preinstalled and can be found as the "Components" tab in DevTools.
|
|
Use the Selector (top left) to select the UI Element. Now you can see all callbacks, props or jump to the source
|
|
directly.
|
|
|
|
If it is anything else, or you're too lazy to use React DevTools, hit `CTRL + Shift + F` while in DevTools and
|
|
enter a search term, for example "getUser" to search all source files.
|
|
Look at the results until you find something promising. Set a breakpoint and trigger the execution of that part of Code to inspect arguments, locals, etc...
|
|
|
|
### Writing a robust patch
|
|
|
|
##### "find"
|
|
|
|
First you need to find a good `find` value. This should be a string that is unique to your module.
|
|
If you want to patch the `getUser` function, usually a good first try is `getUser:` or `function getUser()`,
|
|
depending on how the module is structured. Again, make sure this string is unique to your module and is not
|
|
found in any other module. To verify this, search for it in all bundles (CTRL + Shift + F)
|
|
|
|
##### "match"
|
|
|
|
This is the regex that will operate on the module found with "find". Just like in find, you should make sure
|
|
this only matches exactly the part you want to patch and no other parts in the file.
|
|
|
|
The easiest way to write and test your regex is the following:
|
|
- Get the ID of the module you want to patch. To do this, go to it in the sources tab and scroll up until you
|
|
see something like `447887: (e,t,n)=>{` (Obviously the number will differ).
|
|
- Now paste the following into the console: `Vencord.Webpack.wreq.m[447887].toString()` (Changing the number to your ID)
|
|
- Now either test regexes on this string in the console or use a tool like https://regex101.com
|
|
|
|
Also pay attention to the following:
|
|
- Never hardcode variable or parameter names or any other minified names. They will change in the future. The only Exception to this rule
|
|
are the react props parameter which seems to always be `e`, but even then only rely on this if it is necessary.
|
|
Instead, use one of the following approaches where applicable:
|
|
- Match 1 or 2 of any character: `.{1,2}`, for example to match the variable name in `var a=b`, `var (.{1,2})=`
|
|
- Match any but a guaranteed terminating character: `[^;]+`, for example to match the entire assigned value in `var a=b||c||func();`,
|
|
`var .{1,2}=([^;]+);`
|
|
- If you don't care about that part, just match a bunch of chars: `.{0,50}`, for example to extract the variable "b" in `createElement("div",{a:"foo",c:"bar"},b)`, `createElement\("div".{0,30},(.{1,2})\),`. Note the `.{0,30}`, this is essentially the same as `.+`, but safer as you can't end up accidently eating thousands of characters
|
|
- Additionally, as you might have noticed, all of the appove approaches use regex groups (`(...)`) to capture the variable name. You can then use those groups in your replacement to access those variables dynamically
|
|
|
|
#### "replace"
|
|
|
|
This is the replacement for the match. This is the second argument to [String.replace](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace), so refer to those docs for info.
|
|
|
|
Never hardcode minified variable or parameter names here. Instead, use capture groups in your regex to capture the variable names
|
|
and use those in your replacement
|
|
|
|
Make sure your replacement does not introduce any whitespace. While this might seem weird, random whitespace may mess up other patches.
|
|
This includes spaces, tabs and especially newlines
