Hi,

I wanted to know how to properly load an external transformer by setting the transformer inside the pyproject.toml file?

This is my project file:

[tool.robotidy]
load-transformers = [".robotidy/examples_transformer.py"]

But when I tries to run robotics, I got the following error:

> robotidy file.robot

 Try 'robotidy -h' for help.

Thanks for the report, I have identified two issues:

• we are using both load-transformers and custom-transformers option names (which is fine) but we're only handling "custom-transformers" in the file configuration
• documentation only mentions "load-transformer" (and with typo - no s)
