Finished working on improving exceptions in @LIPS_scheme Now I need to write unit tests

Have a real case of Heisenbug in unit test for my #JavaScript #OpenSource project @LIPS_scheme. One assertion fails, but only if there are an exact number of assertions in two tests. If I add a log or remove any of the assertions (not the one that fails), the test passes.

SRFI 267: Raw String Syntax example implementation inspired the creation of the LIPS Scheme macro to define new hash syntax. Which are a poor man's syntax extensions. It works out of the box with the current beta version of LIPS. Link to SRFI in the comments 👇 #Scheme #lisp

@hello_777_world @nodejs @LIPS_scheme The final solution: I needed to handle complex numbers and big float numbers, which need different rounding.

It looks like @nodejs broke how ** operator works in @LIPS_scheme. My code was testing: (expt 0.5 -1/2) which executes 0.5 ** -0.5 It use to return 1.414213562373095 now it returns 1.4142135623730951 I'm not sure how to fix the tests, so they work in all version of Node.

A new beta version of LIPS Scheme just got released

Thanks to Niels Wijers, LIPS #Scheme now is available as lips npm package. You can install it with npm install lips@beta #JavaScript #lisp

Just written a new article about internals of syntax extensions in @LIPS_scheme, my #Scheme implementation in #JavaScript. Syntax extensions are a way to add new syntax to the language. Link in the comment 👇

Do you know that Lisp is the second oldest programming language that is still in use? Learning lisp can make you a better developer even if you don't use it I recommend starting with Scheme. This is the language that inspired JavaScript. And the reason you have closures

Just published a new article about my project @LIPS_scheme internals. LIPS is a #lips interpreter written in #JavaScript

It took few days, but I finally found the root cause of breakage of this code in @LIPS_scheme The continuations were not working properly even after implementing for-each in Scheme. The problem was apply function that was part of the for-each code. #lisp #scheme

Just when I've though that continuations in @LISP_scheme are all working, fund another bigger example, and then I was able to create this minimal one. The code should exit after the first call, but it continues to loop through the list. #lisp #scheme

Huge achievement today 🎉 While writing a comment on @GitHub why new interpreter in @LIPS_scheme is async. Got an idea about replacing async..await with generators (yield). All it takes was this function, the inspiration came from Babel. #JavaScript
