Just to pick nits, it's an online interface to Zilog's own compiler running on a server, not strictly a new (or online compiler). That methodology is distinct from (say) emSPASM-ng in SourceCoder 3, which is the assembler cross-compiled from source to Javascript and running directly in the browser. :)

I'm wondering what your definition of online is then. emSPASM-ng definitely not considering it's running in your browser. (Not saying that any tool is better/worse, I just don't understand the point you are trying to make)

I was just making the point that there hasn't been a new, non-ZDS compiler developed, and that this is rather a wrapper around the existing ZDS compiler, running as a daemon to compile any waiting programs. I make that distinction primarily because the ZDS compiler has a lot of shortcomings that a new, community-written compiler would be able to fix, and unfortunately, this is not that.

Ah, I see. That's definitely a valid point, I was just confused by the methodology comparison in your first post.

I've updated the news post a bit. Could someone tell me whether I'm still missing the mark anywhere?

The online editor and front-end to the C compiler is coming along nicely. We're trying to find a balance between "release raw tools too early" and "implement everything we've thought about before a release", both of which are pitfalls to be avoided :)
We hope to open public beta-testing by the end of next week.

In order to reduce development time for possible future features, the design supports multi-file projects, multiple types of projects, and permissions, although a subset of that is currently implemented.

We believe that this kind of development tools aiming at a community of developers should be released as open source software, except for the parts directly tied into website infrastructure, of course. Making community-developed closed-source / proprietary tools, e.g. IDEs and emulators (both online and offline), is a mindset of the past, and is toxic to the community.

We'd all wish that there be a modern open source cross-compiler for the Z80 and eZ80 with good C language support, but that's beyond anyone's free time budget. Anyway, the generated code would be lackluster, as those ISAs are poorly suited to C programming (eZ80 somewhat less so).
