Formatting strings
GoLand provides a feature that identifies Printf-like functions and applies corresponding coding assistance. This includes inspections, quick-fixes, spellchecking, highlighting, code folding, and similar actions.
A function is automatically recognized as Printf-like if it meets the following criteria:
It is a function or method.
Its name ends with
f(for example,Printf,Sprintf,Foof).It has at least two parameters.
The second-to-last parameter is a string.
The last parameter is variadic and of the empty interface type (
interface{}).
In the following screenshot, Printf-like functions are highlighted in green.
If a function is incorrectly recognized as a formatting function, you can exclude it from the list. You can do this by using intention actions (Alt+Enter) or by configuring the settings.
