xonre··on LuaJIT 3.0 proposed syntax extensions
For readability, `then` allows splitting with newlines very long conditional expressions, without having to wrap the condition in parentheses:

  if x + y + z > a
    or verylongconditionalhere ()
    or anotherverylongconditionalhere ()
  then
    ...
after `if` and `elseif` the parser simply goes on until it finds `then`.
xonre··on C++: The Documentary
Still true for C++. Can still mentally map new features to the core language C. A modern Cfront transpiler can still be written.

Template meta-programming maps to C pre-processor macros. The sad part with both is generated code cannot be examined thus the unreadable compiler errors and slower compilation as it's regenerated every time.

Slightly off-topic: Rust can also be mentally mapped to C.

xonre··on C++26 is done: ISO C++ standards meeting Trip Report
That place is C++/Lua, with most of the code in Lua. Concurrency model is thread-per-lua-state. Interthread comms is message passing implemented via textbook c++11 atomic and condition variables. Lua is just a small C library so the style remains very friendly to those who like C with classes.
xonre··on PHP 8.5
PHP should do a real major compatibility break and remove $ sigil from variable names. It's gonna be worth the pain!
xonre··on Precompiled headers and why Squid won't be using them (2023)
Tl;dr: it's an autoconf problem

Article also misses: comparing speed of full rebuilds. Pch gives massive speedup on edit-compile-debug cycle or when several modules can share a single pch.

xonre··on Show HN: Lux – A luxurious package manager for Lua
Yes you should.

You'll need a glob function, cd/getcwd/setcwd, pretty-printer. That's about it.

Lua stdlib replaces sed, awk, grep, cut, tr, tail, etc.

Startup time is the best. In my testing, a lua script that functions like `echo` runs faster than echo.

Load the table. Modify. Serialize to file.

Not too hard. Emacs does it with the .emacs file, mixing generated and manual content.

Lua is C in Lisp's clothing.

Lisp killer features were GC, good data representation, first class functions. Lua has all that and more. But its being a "thin" library over the C runtime shows through the clothes.

xonre··on C++ is an absolute blast
You are correct wrt to iostream, it's bad. I stick to studio.h.

It's probably auto when you wanted auto&.

A copy was made instead of a reference. I've been bitten by that.
