Slashdot reader [4]oliwer points out "they are also including a REPL, which could be interesting." And the CJIT web page promises there's "no EULA to sign, no IDE to install... 100% Free and open source!"
It also says the project was inspired by [5]Terry Davis (TempleOS) and Fabrice Bellard (Tiny C Compiler).

Seem to recall this product from the 80's, worked really well with better diagnostics than the c compilers of the era...

Anyway, great job! It's fun to see news about a good old-fashioned "we did it because we could" open-source nerd project.

C is my favourite most hated computer language and I use it for everything. I would certainly look into this new tool and will probably hate it just the same.

C interpreters aren't new.
I first used one back in the 1980s.
They don't work very well. C isn't designed to be an interpreted language.

It's compiled "in-memory." It is not "interpreted" per se.

The problem is that small changes, such as tweaking a header file, can have global effects.
So, incremental compilation doesn't work very well.
You can kinda sorta make it work most of the time but with lots of limitations.
Languages designed for interpretation, such as Python, or for incremental compilation, such as Java, don't have the same problems (although they have different problems).

But t's value-add is presumably interactive development because it is used like an interpreter. It's a modified interpreter with better performance, something of value to no one these days.

Or custom plugins in other products, just like what you can do with Lua on nginx, or custom rules in firewalls or other similar engines. Throw in some sandboxing and you have a very powerful/dangerous tool.

C is the worst language available, except for all others that have been tried.
Well, not quite. But essentially all programming languages suck. The right tool for the right task makes them suck a bit less and for many tasks, C is it.
