问题
There could be a little misunterstanding in live templates in Intellij IDEA. I mean default values for variables in templates.
Suppose we have this live template
What I expect here, that when calling this template (type jqon and press TAB) I will see default values already typed which I can change or leave as it is. Like this
But no. I have empty strings instead of default values
Why?
回答1:
I was wrong about Default value field. I don't need this in my case. I need to fill Expression field.
If I want just paste some string as default value I should put this string in quote in Expression. So now my variable settings look this way
And everything works how I want!
回答2:
If you want a hardcoded string as the default value field (in the edit variables dialog), it needs to be in double quotes ("ii"). Putting a string there with no quotes (ii) does not result in an error, but also does not work.
