Welcome to the weird and wonderful world of esolang creation! I think it's a very fun meta-game part of PPCG to make new languages, and it's one that I enjoy a lot. I'm certainly not an expert on the topic, but I have made two languages before. Here are some tips I'd give you. Keep in mind that all of these are optional:
People in TNB love learning new languages. Mentioning it there is very likely to get at least a couple of people interested in it.
TIO is a website hosting online interpreters for practical and esoteric languages, generously hosted by our moderator Dennis. At the time of writing this, there are nearly 500 different languages hosted on TIO, and adding yours is surprisingly easy. To have your language added, ping @Dennis
in The TIO chat room, and he will tell you what you'll need to do. From there, you can now use your language online at tio.run/#<your-language>
You may also prefer to host your own online interpreter, for example, if your interpreter is in Javascript. This is perfectly valid too. Make sure to include a permalink feature, so that you can link people to a particular code snippet.
Make some docs
The most fun part of writing a new language is seeing other people use and enjoy it. It's very satisfying to know your language is enjoyed by people other than you. But they'll need a way to learn it.
Presumably, your code is hosted on Github, or something similar. Github has a wiki feature, which is ideal for posting language documentation. What exactly your docs will have is entirely up to you, but most people will generally do some combination of the following:
- Specifications
- A tutorial for beginners
- A full list of commands
- Some useful examples in your language
- How to run your interpreter
You can also include docs in the directory of the project itself. Personally, I prefer wikis, but either way is perfectly fine.
Make a chat room
A lot of esolangs can be hard to learn. So it's really nice to have a place where you can talk directly to the expert on the language. Chat rooms are perfect for this. It's also perfectly fine to talk about your language in The Nineteenth Byte, but sometimes talking about one language too long can dominate the conversation. (If lots of people are interested)
Your mileage may vary on this tip. I have two language chat rooms. One of them is constantly frozen and has no one there wanting to talk. The other is usually somewhat active every week, and will have people talking in there with or without me. In order to avoid making a new dead room, it might be wise to wait and see how often people want to talk about your language.
Answer noteworthy questions in your language
Here are some examples of very famous questions that are a catalog of how to do the task in may different languages:
These have the added benefit of being fairly simple tasks that help you get a hang of how to use your language.
You can answer more than these challenges too! The more challenges you answer, the greater the chance of getting people interested.
Those are the main ones. Here are some extra things you can do:
Make a tips question
A tips question is a great way to show off how to golf in your language, and to share your knowledge with the community so that they can learn how to golf in your language as well. If your lucky, sometimes you'll even be blown away by the users of your language, and learn something you didn't even know of yourself!
Nominate your language for Language of the Month
Language of the Month is a new contest started by DLosc, intended to bring awareness of obscure languages to the community. If you can get enough people interested in learning your language, you might get to have it featured for a month, which will bring it to way more people. Disclaimer: If your language is seen as a cheap derivative, or as not creative, it might end up being downvoted. This option mostly depends on how original/interesting your language is
Make some bounties for your language
Nothing gets people motivated to learn a new language like rep does! We have a meta post for endless bounties, which is where people offer some of their own reputation to see particularly difficult tasks completed. If you come up with a task in your language (e.g. outgolf me, do X in < Y bytes, Do particularly hard task, write a quine, etc.), you can incentivize people to learn your language by offering up your own rep.
The esolangs wiki is a site that PPCG loves a lot. Basically, it's like wikipedia but for esoteric programming languages. If you include your language here, there's a greater chance of it being discovered by people outside of PPCG.
