I tried to find documentation for supporting multiple languages with no success. Is localization supported for documentation generation?
Sorry, currently localization is not supported. I think this is out of scope for the time being so I'll close this issue but feel free to continue discussing your ideas here.
This is the solution to my question. We have created a typedoc plugin which is:
In the Readme.md you can find more detailed explanation of the steps that you should take to use the plugin.
Very cool! Do you want to add that to the typedoc readme?
That would be great! If there is something that we need to consider as a plugin requirements or repository configuration, just let me know.
Sharing with the community steps and a video representation of the localization plugin usage:
npm install typedoc-plugin-localization
npx typedoc projects\igniteui-angular\src\public_api.ts --generate-json exports
npx typedoc .\projects\igniteui-angular\src\public_api.ts --generate-from-json .\exports\ --out localized
For more information, have a look at the readme.md file.
