[PYTHON] Source code character code check script

Introduction

A long time ago, it became necessary to check the character code of the source code, so I made it with python and made it run regularly with Jenkis, so that memo

Why is it necessary to check the character code of the source code?

• When developing a game, overseas support comes out, and if Japanese is written in the source of s-Jis, it tends to be a problem.

• If you look at the source code on the web, the comments will be garbled! (It's hard to check the code on the go)

• Even though I wrote a comment in Doxygen format, everything is garbled.

• Incomprehensible compilation errors may or may not occur.

Implementation

	start_time = time.clock()

	#Project directory

	ret = True

	
	for (root, dirs, files) in os.walk(path):

			base, ext = os.path.splitext(file_path)

					break;
			
			if ignore == True:
				continue
			
			if ext in extention:
				try:
					f = open(file_path, 'r')
					data = f.read()
					p = chardet.detect(data)

				finally:
					f.close()

	end_time = time.clock()
	print("complete![time: ",(end_time - start_time),"sec]")
	
	if ret == False:
		CODE='S001'
		MESSAGE='shift-jis still exists!!'
		EXPECTED='S999-error'
		ACTUAL='sample ' + CODE +' '+ MESSAGE

• Then regularly at Jenkins

The s-Jis source is output to the log like this.

• Currently, there are 78 ** s-Jis files in Asta Breed. ** It's just a source that is not related to language support, so leave it alone (´∀ ｀)

That's it.
