[TYPO3-english] [6.2.5] How to? condition with string comparision of a constant (in page setup typoscript)

[Patrick Bierans]

Hello Community!


After years in typo3 4.6 I decided to look at a fresh new 6.2.5.
Right now I think I missed something and wanted to ask you.


My constant for the root page (web > template) is:

# cat = basic/presets; type = options[dev,stage,prod]; label = enviroment preset
config.preset = dev
~

Based on the constant I want to change the page setup:

# to see the constant in the typo script object browser:
config.preset = {$config.preset}

# this has to change now:
config.presettest = idontknow

# How do I have to write this condition so it works?
[globalString = {$config.preset} = dev]
  config.presettest = devenv
[global]
~

I tried different interations with globalVar and LIT: 
and switched the operants but something seems wrong in general.

What am I missing?


TIA!
