maya_mel转python代码插件
这个⼯具，因该是像我这种懒⼈的福⾳啦，我是⼀个maya mel程序⽼⽤户了，算起来有10多年了，python现在逐渐成为主流DCC接⼝语⾔，但⼈都有惰性，⽽且mel是maya内置的native语⾔，⼀般⼯作所需都够⽤了，但python流⾏除了语法精炼外，还有其跨平台兼容想好的优点，所以⼀套ui⽂件，可以应⽤在不同的软件⾥使⽤。那其实python只不过将mel脚本转义为python脚本，⽽且是对应的关系，甚⾄作为第三⽅maya python脚本pymel语⾔其实更加的python风格化，直接提供了mel转换为python代码的功能。
从此mel程序员解脱了… 哈哈哈哈哈哈哈哈哈哈哈哈 … 坏了收不住了…哈哈哈…
本套插件使⽤的就是这个pymel中tools包的mel2py模块功能：
maya中的插件界⾯如下：
ezMel2Python.py 内容如下：
# -*- coding: utf-8 -*-
import os
as pm
ls.mel2py as mel2py
def em2pConvMel2Py():
u'''translate MEL to Python'''
melCmd = pm.scrollField( 'em2pTextEditMEL', q=1,tx=1 )
pyCmd =  l2pyStr(melCmd,pymelNamespace='pm')
pyFixed = place("pymel.all","")
pm.scrollField( 'em2pTextEditPy', e=1,tx=pyFixed )
def ezMel2Python():
try:
em2pUIFile = os.path.abspath( __file__ ).split('.')[0] + '.ui' # same folder this script
except:
print u'Error,can\'t load UI.'
return
if pm.window('ezMel2PyWin', exists=1) :
pm.deleteUI( 'ezMel2PyWin' )
ezMel2PythonWindow = pm.loadUI( uiFile = em2pUIFile )
pm.showWindow( 'ezMel2PyWin' )
pm.window('ezMel2PyWin',e=1,tlc=(200,250) )
ezMel2Python.ui ⽂件内容如下：

将以上三个代码⽂件，拷贝到maya ⽤户 scripts下，之后打开maya，将插件l托⼊maya即可弹出插件界⾯。
