Could anyone plese suggest me most effective plugin for robot framework which shows compilation error during development.
Hi,
RF doc gives this:
And if you search the forum for “pyCharm plugin” there are other solutions, but I think the issue is maintainability and support of the tools.
I’m not using it now, but can tell you VsCode with Robotcode extension work like a charm 
Regards
Charlie

To expand on this:
Robotcode is developing a version of the extension for Pycharm, but is still in the works (although I believe you can install it). Once it is ready, I expect it will be the best option, assuming it allows for debugging like it does in VS Code.
In the meantime, I believe Hyper (mentioned in documentation Charlie linked) works the best. I don’t use Pycharm myself, but I know of a coworker who was investigating this recently and went with Hyper.
