IO.inspect has long been my go-to technique for troubleshooting code that isn’t quite working how I would expect. Since the :label option was added in 1.4, I use that all the time, too. The majority of the time, I use it to inspect one or more variables like so:
IO.inspect(foo, label: "foo")IO.inspect(bar, label: "bar") However, I often find my self making simple, dumb mistakes when setting this up, such as copying and pasting a prior IO.inspect line, but forgetting to update the label, e.g.: IO.inspect(foo, label: "foo")IO.inspect(bar, label: "foo") # woops, the output will label this as `foo`, too! Given how common this pattern is, it would be really nice if there was a function or macro to do this for us. I’m thinking something like: # inspect each variable in the current scope, labeling each with its nameIO.inspect_vars(:all) # inspect just the provided variables, labeling eachIO.inspect_vars([foo, bar]) # inspect all variables in the current scope, except the provided ones, labeling eachIO.inspect_vars(except: [foo, bar]) I can also imagine it supporting a label option, to put a title above the list of variables, in order to distinguish multiple variable reports. Would others find this as useful as I would? Is there interest in it being added to Elixir? Thanks!
