Hi all, I've been asked several times to allow dots (".") as a valid character in device names. My question is … are dots officially allowed? I remember that in Tango 8 database (~2014) the usage of dots and spaces in device names was causing problems on writing/retrieval of properties. Was this already solved? Which is the list of "officially accepted characters"? Sergi |

Hi Sergi, As far as I know, the only reserved characters are defined in this documentation section: https://tango-controls.readthedocs.io/en/latest/development/general-guidelines/naming.html?highlight=naming#reserved-words-and-characters-limitations From the naming schema described above, the reserved characters are ':', '#', '/' and the reserved string is : "->". On top of that, the dbt_update tool (tool to fulfill database from the content of a file) reserved the "device" word So I think dots are not forbidden in device names but I would definitely avoid spaces and tabs which can be confusing because you might not see them well in jive. Are there still bugs related to that? I don't know. Use it if you feel lucky, and report any issue you might encounter! I made a quick test creating devices with dots using jive 7.19 and it seems to work fine. Reynald

Hi, Sergi, we are interested in using dots, thank you for you question. :) I remember we talked about this with Pascal and Reynald in TANGO meeting in Firenze so the answer of Reynald is comforting. Thanks guys.
