help with scripting

[nemsi]

Hi guys,

i would like to make a simple script that add/creat a hbatch *.cmd file with this inside :

mread $JOB/render/$HIPNAME.hip
Redshift_setGPU -s 11
Redshift_setLogLevel -L 5
render /out/Redshift_ROP1

Then it would automatize my process.

Thank you for your help.

Hi, do you want to use python to create the .cmd file? If it is so, than this might work for you:

import os

path_hip     = hou.expandString('$HIP')
path_scripts = path_hip + '/scripts/'

if not os.path.exists(path_scripts):
    os.makedirs(path_scripts)

script   = 'some text'
path_cmd = path_scripts + 'filename.cmd'
file_cmd = open( path_cmd, "w")
file_cmd.write(script)

I use similar script, but I am no python guru unfortunately, so there may be a better way to do it.

Thank you Ikoon!!

the main is there. Do you know how to :

- get a "retur to the next line" for my script variable?

- translate a $JOB to its value when writing in the file (again for script variable)

Thank you for your valuable help!

Hi,
as regards evaluating the $JOB as a string, this should work

hou.expandString('$JOB')

For multiline string in python, you can see few methods here (scroll down to answers)

I use \n and multiple += when I am building the script, for me it is most readable:

        variable    = 'some_filename.hip'
  
        script_rop  = '# commented first line\n'
        script_rop += 'hou.hipFile.load("' + variable + '")\n'
        script_rop += '# another line\n'
        script_rop += '# last line, without backslash n'
