#preprocessor — Public Fediverse posts

If you were writing a #compiler (or, in my case, a #preprocessor) and you had to think of a variable name for a "class" struct, but you can't use the keyword class... what would you call that variable?

Plot twist: The compiler/preprocessor is written in #ObjectPascal. (So it's actually a record, not a struct. Same difference.)

I'm currently using the variable name class_item which is a very un-Pascal identifier for many reasons. I'm thinking of using PClass or PsiClass just to get around it.

REPOST (JAN 2024): My first thoughts on #Psion's dialect of Object Oriented C for the Series 3 and related portable computers.

Includes the JPI/Clarion #TopSpeed #compiler, a proprietary preprocessor, the Eiffel programming language, and a handful of calling conventions.

Also, did somebody say Objective-C?

This is an old blog post from the beginning of the year. If you've been following my journey in recreating #CTRAN, this was written a week before I decided to take the plunge.

(Yes, I did say in the article that I definitely wouldn't be writing a compiler. I did say that.)

As someone hearted ❤️ a 2015 demo of mine, I decided that since #CSS got better (and hopefully I did too), I should go for a quick 2024 remake.

It's mindblowing 🤯 how much I could reduce the (esp. compiled) code - check it out!

HTML by 73%!
CSS by 70%!

I repeat: I shaved off at least 70% from each! ‼️

I wonder if anyone has seriously thought about adding some kind of namespacing to the C preprocessor.

for example, it would be nice if you could say

#namespace FOO
#include "foo.h"
#endnamespace

and then all the preprocessor defines from foo.h are brought into your file with names like FOO###BOOL

#c #preprocessor #cpreprocessor #cpp #wg14

STM32. Процесс компиляции и сборки прошивки

Многие из начинающих разработчиков софта для микроконтроллеров реализуют свои проекты исключительно в средствах разработки, которые предоставляются производителем. Многое скрыто от пользователя и очень хорошо скрыто, из-за чего некоторые воспринимают эти процессы сродни настоящей магии. Я, в свою очередь, как человек в пытливым умом и природной любознательностью, решил попробовать собрать проект без использования IDE и различного рода автоматизаций. Так родилась идея для этой статьи: не используя ничего, кроме текстового редактора и командной строки, собрать проект мигания светодиодом на отладочной плате STM32F0-Discovery. Поскольку я не до конца понимал, как происходит процесс компиляции и сборки проекта, мне пришлось восполнять пробелы в знаниях. Разобравшись с этим вопросом, я подумал — а почему бы не рассказать другим об этом? Всем кому интересно — добро пожаловать под кат! 🙂

@jhx You asked for it, so I'll answer it:

Imho, C++ design is broken from the very beginning. It wanted to provide #OOP language constructs, still maintaining full #C compatibility (which already failed many years ago, cause the languages took different roads).

It combines #exceptions (IMHO generally a bad idea) with explicit resource management (an *awful* idea, forcing you to use #RAII which will in turn mandate creation of purely "technical" classes, just to manage resources).

It wanted #generics, but that's impossible without breaking C compatibility, so it came up with #templates, actually a #preprocessor on steroids.

Overloading also doesn't fit into the simple C library ABI (where #linker symbols are named just like the function), so it came up with "name mangling" ... which is especially horrific because it is *not* standardized.

Ah well, I could go on 😂
