Not just C++: Thoughts on Dealing with Signed/Unsigned Mismatch – IT Hare on Soft.ware

Posted by jpluimers on 2018/10/02

[WayBack] C++: Thoughts on Dealing with Signed/Unsigned Mismatch – IT Hare on Soft.ware.

I have seen things like this happen in way to many places, not just C/C++:

static_assert( -1 < 1U );//fails!

Take away:

Never ever use explicit casts merely to get rid of warnings (whether signed/unsigned or otherwise)

A way to set various C/C++ compilers apart: [WayBack] GitHub – shafik/determine_c_or_cpp: Determine programatically C from C++ as well as various versions

aha (Ansi HTML Adapter) with clickable URIs

Posted by jpluimers on 2018/10/02

aha is great to generate HTML from ANSI text (i.e. the coloured output on a Linux console).

But it doesn’t generate clickable URIs (it can’t yet by itself as it only looks one character in the future).

The thread at https://github.com/theZiz/aha/issues/20 suggested a case-insensitive regex through sed but the exact suggestion failed for a few reasons I will explain below.

First the bash alias (requires both aha and perl):


#!/usr/bin/env bash
# based on https://github.com/theZiz/aha/issues/20#event-797466520
aha-with-expanded-http-https-urls()
{
aha | perl -C -Mutf8 -pe 's,([^"])((https?|s?ftp|ftps?|file)://.*?)([\s]|\&quot;\s),$1<a href="$2">$2</a>$4,gi'
}

Reminder to self that this cleared itself: Delphi fails to start after Windows did some “Program Compatibility Assistant” magic…

This repaired itself; weird: [WayBack] Delphi fails to start after Windows did some “Program Compatibility Assistant” magic to it when BDS.exe crashed because the compiler ran out of memory:… – Jeroen Wiert Pluimers – Google+
