Patches

This page includes patches that some might find useful for customizing yocto beyond what the wizard script allows.

Disable unicode

For simplicity and performance, tested on commit 7617f6a

Logging function

useful for debbuging

void log(const char *str, ...)
{
	FILE *logfile = fopen("/tmp/yocto-log.log", "a");
	va_list args;
	va_start(args, str);
	vfprintf(logfile, str, args);
	va_end(args);
	fclose(logfile);
}

Line numbering

Line numbering is on by default (because I like it), with 3 digits, and one more for overflows (second image) This patch increases the digits to 5+1. Tested on commit 7e416f0
