What's wrong with bash though? Targeting bash specifically has massively improved my productivity and decreased the incidence of easily avoidable mistakes. Portable POSIX shell scripting is hell on earth but bash scripting with shellcheck can be surprisingly pleasant. I had the same experience with portable makefiles and GNU Make. For example, I managed to create a surprisingly good test suite with bash and the rest of the GNU coreutils: https://github.com/lone-lang/lone/blob/master/scripts/test.b... It even runs in parallel. Submitted a patch to coreutils to implement the one thing it couldn't test, namely the argv[0] of programs. I should probably go check if they merged it...

Not too long ago, a project of mine was shared here on HN. https://news.ycombinator.com/item?id=38126052 In that thread I wrote: > I have this vision in my mind: embedding lone modules into sections of the lone ELF and shipping it out. Zero dependencies, self-contained. I've been working on that since that day. Proud to say I've gotten it to work and thought I'd make it the subject of my first Show HN. Some free software projects gained features along the way too. The link is to an article with a proper demonstration, technical details and what happened in the past few weeks. The complete repository itself can be found here: https://github.com/lone-lang/lone I've completely reorganized it since the last thread. Would be very happy if you guys tried it out.

Yeah, she actually got that feature standardized. Apparently it's a binary version of the feature used in those self-extracting installer .run scripts. I finished the embedded segment loading feature by the way. I'm writing that article as promised but if you'd like to check it out ahead of time: https://github.com/lone-lang/lone/blob/master/source/tools/l... https://github.com/lone-lang/lone/blob/master/source/lone/au... https://github.com/lone-lang/lone/blob/master/source/lone/se... https://github.com/lone-lang/lone/blob/master/source/lone/mo...

To test my programming language. It's a freestanding lisp interpreter that doesn't link to libc. I wrote the code that handles the environment variables and in order to test it I needed full control over the program's inputs including its environment. The env utility provides this control by emptying the environment and setting only the variables I specify, solving 90% of the problem. Only thing I still can't control is argv[0]. With this new feature upstreamed, my test suite will be complete. Here's the code if you wish to take a look: https://github.com/lone-lang/lone#testing https://github.com/lone-lang/lone/blob/master/scripts/test.b... Without env -i, the folllowing tests would not be possible: https://github.com/lone-lang/lone/blob/master/test/linux/env... https://github.com/lone-lang/lone/blob/master/test/linux/env... https://githu

> only to be confronted with the notorious 'incompatible glibc version error'. It's super annoying. I started making my own freestanding Linux Lisp because of this exact issue. It's nowhere near as performant as something like SBCL but it's small and has zero dependencies. Once compiled it will literally run on any Linux of the same architecture. https://github.com/lone-lang/lone I'm taking a break from this project at the moment but eventually I'm gonna add a feature that lets me put a Lisp script into the ELF itself so I can just copy it with the scripts included and have a totally self-contained freestanding Lisp executable.

The kernel just copies the data to the program's stack in a contiguous manner. Obtaining pointers to them can seem somewhat magical if you're writing a nolibc program but I wouldn't call it horrible. I implemented it for my programming language with some rather simple assembly code: https://github.com/lone-lang/lone/blob/master/arch/x86_64.c#... https://github.com/lone-lang/lone/blob/master/arch/aarch64.c...

Carmack said low level programming is good for the soul, he's right. C is a fun programming language, don't even know why. Freestanding C with no standard library is the most fun I've had programming ever. I'd like to share my project as well: a Lisp interpreter written in freestanding C. https://github.com/lone-lang/lone
