Greetings,
I am adding a new tool to our in-house Galaxy, which has a few string inputs. I have made each one a text param in the XML, but want to ensure that the user does not leave any empty when he executes the tool.
How can I do this? I tried setting the optional field of each text param to false, but that doesn't work since, technically, an empty string still counts as a string.
Is there a minimum length setting I can enforce?

Hi Ravi, you should use a validator, as in the following example:
<param name="rgid" type="text" label="Read group identifier (ID)"> <validator type="empty_field" /> </param>

Hi Nicola,
Thank you. I tried the validator as you illustrated, and it worked perfectly.

Hi Nicola,
Perchance, do you know what type of validator I can put to ensure that the string input is does not consist of only whitespace? Such a string is still invalid for my tool, but counts as a string.

Hi Ravi, for that you need a regex validator:
https://bitbucket.org/galaxy/galaxy-central/src/tip/lib/galaxy/tools/paramet...
e.g.
<validator type="regex" message="This field should contain some non-whitespace character">.*\S</validator>
Best, Nicola
