MEL To Python2

これがシンプルな状態
import pymel.tools.mel2py as mel2py

pyCmd = mel2py.mel2pyStr(melCmd,pymelNamespace=’pm‘)

pyCmd = mel2py.mel2pyStr(melCmd,pymelNamespace=’cmds‘)でいいのかも

# -*- coding: cp932 -*-
import pymel.core as pm
import pymel.tools.mel2py as mel2py
import re
import math
import random
melCmd = """
$value1 = `floatFieldGrp -q -label "Frame range" -v1`;
	"""
pyCmd =  mel2py.mel2pyStr(melCmd,pymelNamespace='pm')

melで改行をしてる「+”¥n”」と「¥n」を　けしてから

あと、出力結果がPyMelにならないようにしてみたり。

簡単な解決策はmaya2022 以前の2020，2019バージョンを起動してそこでmel2pyを使うことだ。

A simple solution is to launch a maya2020 or maya2019 version prior to maya2022 and use mel2py there.

githubで解決していると思いダウンロードして試したが無理だった

https://github.com/LumaPictures/pymel/blob/master/pymel/tools/mel2py/melparse.py

import pymel_master.tools.mel2py as mel2py
mel_command = 'setDrivenKeyframe "-currentDriver pCube1.translateY pCube2.translateX";setDrivenKeyframe "-currentDriver pCube1.translateY pCube2.translateY";setDrivenKeyframe "-currentDriver pCube1.translateY pCube2.translateZ";'
pythonCode = mel2py.mel2pyStr(mel_command, pymelNamespace='pm')
print(pythonCode)



import pymel_master.tools.mel2py as mel2py
mel_command = '$currentNodes = `ls -sl -l`;'
pythonCode = mel2py.mel2pyStr(mel_command, pymelNamespace='pm')
print(pythonCode)

python3 Error: AttributeError: file C:\Program Files\Autodesk\Maya2023\Python\lib\site-packages\pymel\tools\mel2py\melparse.py line 438: ‘str’ object has no attribute ‘lineno‘

上記エラーがでて無理だった。

１行ならどうにかなるが、関数などの複数行だとこのlinenoが取得できないようでバグるものしか作れなかった

        # cycle through our kwargs and format them
        for flag, value in kwargs.items():
            print("melparse.py  - format_command() - "+" flag= "+str(flag)+" ,value= "+str(value))
            if value is None:
                value = '1'

            # multi-use flag
            #    mel:     ls -type "transform" -type "camera"
            #    python:    ls( type=["transform", "camera"] )
            if isinstance(value, list):
                #sep = ', '
                # if len(value) > t.lexer.format_options['kwargs_newline_threshhold']:
                #    sep = ',\n\t'
                #pargs.append( '%s=[%s]' % ( flag, sep.join(value) )  )
                value = assemble(t, 'multiuse_flag', ', ', value, matchFormatting=True)
                #pargs.append(Token('%s=[%s]' % (flag, value), None, flag.lineno))
                pargs.append(Token('%s=[%s]' % (flag, value), None, 0))#mycode
            else:
                print("melparse.py  - format_command() -  flag= "+str(flag))
                #pargs.append(Token('%s=%s' % (flag, value), None, flag.lineno))
                pargs.append(Token('%s=%s' % (flag, value), None, 0))#mycode

本体の更新に期待する。
