Running Liquid with different values of Liquid::VariableStart/End in the same application

[cernyjakub]

Hello!

I am upgrading a big legacy Rails app, which uses a patched Liquid, where Liquid::VariableStart/End are redefined to avoid syntax clashes with some old data.

I am adding a new part of the application, in which I want to use standard "vanilla" Liquid syntax. At the same time, the old part needs to keep working.

Do you have some ideas how to run the 2 modes in the same app? In last versions, there is a concept of Environments, however they do not allow to redefine these low-level constants.

I am not very experienced with advanced monkey-patching and would like to know if you had some hints or suggestions how to tackle this problem.

Thanks in advance!
