Inori / defer.hpp

Created July 4, 2023 04:05 — forked from pmttavara/defer.hpp

The definitive defer implementation for C++. Syntax: defer { statements; };

	#ifndef defer
	struct defer_dummy {};
	template <class F> struct deferrer { F f; ~deferrer() { f(); } };
	template <class F> deferrer<F> operator*(defer_dummy, F f) { return {f}; }
	#define DEFER_(LINE) zz_defer##LINE
	#define DEFER(LINE) DEFER_(LINE)
	#define defer auto DEFER(__LINE__) = defer_dummy{} *[&]()
	#endif // defer

Inori / FullScreenQuad.hlsl

Created April 18, 2020 22:42 — forked from rorydriscoll/FullScreenQuad.hlsl

A vertex shader that uses the vertex ID to generate a full-screen quad. Don't bind vertex buffer, index buffer or input layout. Just render three vertices!

	struct Output
	{
	float4 position_cs : SV_POSITION;
	float2 texcoord : TEXCOORD;
	};

	Output main(uint id: SV_VertexID)
	{
	Output output;

Inori / ExtractAudio.bat

Created March 15, 2020 08:29

Add ExtractAudio ability to right click SendTo menu by calling FFmpeg

	@echo off
	set SCRIPT_ROOT=%~dp0
	set FFMPEG=%SCRIPT_ROOT%ffmpeg.exe

	set INPUT_FULLPATH=%1
	set INPUT_FILENAME=%~n1
	set INPUT_FOLDER=%~dp1
	set OUTPUT_FULLPATH="%INPUT_FOLDER%%INPUT_FILENAME%.mp3"

	echo Extraction audio from %INPUT_FULLPATH%

Inori / vk.cpp

Created October 20, 2019 17:14 — forked from SaschaWillems/vk.cpp

Multiple Vulkan buffer binding points

	Shader

	layout (location = 0) in vec3 inPos;
	layout (location = 1) in vec3 inColor;
	layout (location = 2) in vec3 inPosB;
	layout (location = 3) in vec3 inColorB;

	...

Inori / LBA原理

Created August 11, 2018 13:20

	首先说明LBA保护是什么。讲到这里就插入一点背景知识。
	PSP的UMD数据基于ISO9660格式存储。（关于ISO9660的具体信息请查阅相关资料）
	众所周知，ISO9660的数据存储基于逻辑块（Logical Block）。数据必须以逻辑块为单位对齐。
	其大小可在VolumeDescriptor结构的logical_block_size中获得。
	在PSP上，这个值是0x800，也就是2048字节。
	sony为PSP的isofs驱动（在用户层一般由disc0访问）提供了一种特殊的访问模式。
	这种模式就是LBA，也就是Logical Block Addressing，即逻辑块寻址模式。
	可以使用户通过提供逻辑块编号和文件长度，直接访问相应位置的数据，而不需要沿ISO数据结构下溯。
	（事实上，下溯的结果也只是这两个数据而已。）
	但事实上，提供这种方法的主要目的并不是节约寻址时间。

Inori / rebuild_jis_filename.py

Created May 1, 2018 13:52

Rename wrong jis codec file

	import os
	import sys


	def jis_rename(root):
	for root,dirs,files in os.walk(root):
	for file in files:
	file = os.path.join(root, file)
	d = os.path.dirname(file)
	f = os.path.basename(file)

Inori / switch-gpu.sh

Last active April 8, 2024 07:32

Switch GPU on Debian system with reboot (same as nvidia-prime)

	#!/bin/bash

	# Switch GPU on Debian system with reboot.

	# Because there's no nvidia-prime package for Debian distro,
	# I did some work to achieve the same functionality as nvidia-prime provide.

	# Follow the instructions here:

	# 1. Follow instructions here to install nvidia proprietary driver:
