Mac OS中SVN工具Versions日期重置脚本

Versions是一个Mac OS下挺棒的SVN工具，不过有日期限制。网上有人提供了将Versions的使用日期重置的脚本，这个脚本有些值得学习的地方。贴出来做个记录。

 

#!/usr/bin/env python

import os, sys, re, plistlib, subprocess, re, time



userdir = os.path.expanduser('~')
prefdir = os.path.join(userdir, 'Library/Preferences')

pfile_a = os.path.join(prefdir,'com.madebysofa.Versions.plist')
pfile_b = 'com.picodev.Versions.plist'

hfile_a = '.CF89AA64'
hfile_b = '.FB64CF89'

globalprefs = os.path.join(prefdir, '.GlobalPreferences.plist')


def convert_plist_to_xml(plist_path):
	cmdline = '/usr/bin/plutil -convert xml1 "%s"' % plist_path
	os.system(cmdline)

def isVersionsRunning():
	p = subprocess.Popen(['ps','-Ac'],stdout=subprocess.PIPE)
	output = p.stdout.read()
	apps_re = re.search('^([0-9]+).*Versions$', output, re.M)
	if apps_re:
		return int(apps_re.group(1))
	else:
		return False

def killRunningVersions():	
	pid = isVersionsRunning()
	if pid:
		sys.stdout.write('Stopping currently running Versions...\n')
		os.system('kill %d' % pid)
	while isVersionsRunning():
		time.sleep(0.1)
		
def relaunchVersions():
	os.system('open -a /Applications/Versions.app')

	killRunningVersions()
	
	pfile_a_path = os.path.join(prefdir, pfile_a)

	if os.path.exists(hfile_b1):

		os.remove(hfile_b1)
	
	# -- 2) Now, delete the expiry token from the globalprefs file...

			plistlib.writePlist(pl, globalprefs)
			
	# -- 2) Make sure that the "FirstRunDate" is also removed...
	if os.path.exists(pfile_a):
		convert_plist_to_xml(pfile_a)
		pl = plistlib.readPlist(pfile_a)
		if 'FirstRunDate' in pl.keys():

			del pl['FirstRunDate']
		if 'EZSBookmarksSelectionMask' in pl.keys():
			sys.stdout.write('Removing EZSBookmarksSelectionMask from "%s"' % pfile_a)
			del pl['EZSBookmarksSelectionMask']
			plistlib.writePlist(pl, pfile_a)
			
			
	sys.stdout.write('Launching Versions....')
	relaunchVersions()
