Re: [Tauruslib-users] Taurus 4 preview available

[Carlos P. <cpa...@ce...>]

You are right. There is a bug already about this in the tracker:

https://sourceforge.net/p/tauruslib/tickets/221/

But note that old eval syntax should be supported in Taurus 4 (it should 
issue deprecation warnings, but it should work). So please fill a bug if 
some previously valid eval name is not working in taurus-4.

Cheers,

Carlos

PS: until the official docs are updated, you can find many examples of 
valid and invalid eval names in 
.../taurus/core/evaluation/test/test_evalvalidator.py
