Dao Programming Language

This has nothing to do with decentralized autonomous organizations of the blockchain world. From the page: Dao is a lightweight and optionally typed programming language with many advanced features. It includes features that can make concurrent programming very simple. It provides well designed programming interfaces for easy embedding and extending.

  Yeah, took me a minute to figure that out, too. I thought this was another EVM language.

This seems really interesting, but it looks kind of dead. That's a shame, I'd love to get into it. EDIT: Ignore me

  Where did you get that idea? https://github.com/daokoder/dao/ https://github.com/daokoder/dao/ Last commit was 3 days ago Project seems relatively active in general: https://github.com/daokoder/dao/graphs/commit-activity https://github.com/daokoder/dao/graphs/commit-activity

I mostly submitted this here because Dao looks kinda interesting but I've never heard anything about it anywhere and thus was reluctant to invest time in it. I know that the language has been around for years, though. Has anyone here every used it?

  Haven't used it either (Google suggests nobody but the author is actually using it seriously), but from a quick look it's basically a virtual machine in C, so probably competitive with Lua / Squirrel / the other dozen lightweight embedded scripting languages. It's probably easiest to just use V8 for any new projects, it's the fastest / most maintained and the scripting API isn't really that much more complicated. Plus basically everyone knows JS these days. https://github.com/v8/v8/wiki/Getting%20Started%20with%20Embedding https://github.com/v8/v8/wiki/Getting%20Started%20with%20Emb... Although Dao does have good concurrency/async features; V8 isn't really POSIX thread safe.

Author here, I will be happy to answer some questions.

  Is it pronounced Dow or Day-o?
  - NeoHermit 9y ago
    Dow. It is the same word as Tao, but in the official Pinyin writing that matches its Mandarin pronounciation.

      What's the Chinese character for Dao (if exists)?
      - haskal 9y ago
        Oh, sorry. 道: found it on the Chinese version.

      Would you please tell my brain. Every time it sees that name it insists on going "Daylight come and I wanna go home."
    - jaxn 9y ago
      That makes me want to check it out more.

  Did you write the GC from scratch? How does it integrate with llvm?

How do I enable the LLVM jit? It doesn't seem to be included in the build system
- NeoHermit 9y ago
  You will need to clone https://github.com/daokoder/DaoJIT https://github.com/daokoder/DaoJIT, and place it under dao/modules. Then edit dao/modules/makefile.dao to add: if( DaoMake::IsDir( "DaoJIT" ) ) modules.AddDirectory( "JIT", "DaoJIT" ); then it will be included in the building. After building, you can add "-j" option in the command line to turn on jit. However, this module has not been tested for some time. It could be broken. It depends on older versions of LLVM, which is unfortunately not available on my laptop, so I cannot verify it now.

It took me a while to realize this is not the DAO from Ethereum, which incidentally, is such a (negatively) loaded name. Maybe you should consider changing the name, at very list just so you don't get dismissed when reading the title alone in any post, newsletter, w/e.

  Note: the Chinese word "dao" predates Ethereum by a very long time. I'd be more worried that it would be difficult to find since the word is so common.
