“A Hex Editor for Reverse Engineers, Programmers and people who value their retinas when working at 3 AM.”
I actually used it not too long ago to inspect why a mp4 file wasn’t valid. The pattern language that they have is quite nice and having sections of the hex highlighted and being able to see what structures they represent and what data was on those structures was very useful!

Traditionally CSS lacked features such as variables, nesting, mixins, and functions. This was frustrating for Developers as it often led to CSS quickly becoming complex and cumbersome. In an attempt to make code easier and less repetitive CSS pre-processors were born. You would write CSS in the format the pre-processor understood and, at build time, you'd have some nice CSS. The most common pre-processors these days are Sass, Less, and Stylus. Any examples I give going forward will be about Sass as that's what I'm most familiar with.

Where cloak.h is https://github.com/pfultz2/Cloak/blob/master/cloak.h
The above macros are admitttedly very hairy. If C had a better preprocessor, but was otherwise unchanged, they could look a lot nicer.
> I never said such a thing. Would appreciate if you didn't put words in my mouth.
A normal part of dialogue is, "I'm going to repeat your point back to you in my own words, and you can either agree with my restating of it, or point out at which point I've misunderstood you". That's what I was doing. "Would appreciate if you didn't put words in my mouth" is unnecessary hostility.
> In my concrete example, given that FILE and DIR were classified as objects, to which of the so-called objects does F(const char*, FILE, DIR) belong?
Take any language which you agree is "OO". Add one new feature (if it isn't already there): functions/methods which don't belong to any class/object. Now the function you are talking about is possible in that language. Did the language thereby suddenly cease to be OO when we added that feature? Most people would disagree with "Yes". But if "No", what is the actual difference between C and that language?
Neovim uses the Vim colorschemes, which themselves seem to have undergone some improvement thanks to being updated using this tool called vim-colortemplate.
> QBE is a new optimizing backend much simpler than LLVM; cproc and cparser are two of the C compilers that target it, in addition to its own minic.
I thought cparser targeted libFirm. That's what their GitHub page says [0].
"It acts as a frontend to the libFirm intermediate representation library."
> We really need a production quality open source C compiler that is actually written in C.
I honestly think cproc or cparser are almost there already. For cproc, you just need to improve the quality of code optimization; it's really QBE you'd need to change. For example, you could change unnecessary multiplications by powers of 2 into left shifts, improve instruction selection so that subtraction is always something like "sub rax, rdi" and not "neg rdi / add rax, rdi" [1]).
For cparser, I notice slightly higher quality codegen; libFirm just needs more architecture support (e.g. AMD64 support appears to work for me, but it's labeled as experimental).

There are tools to do exactly that, like a simple bash scripts lit.sh: https://github.com/vijithassar/lit
I've heard it referred to as 'semi-literate programming' because it skips the reorganization functionality and just gives you nice prose to code conversion.
