View Source Credo.Check.Readability.PreferImplicitTry (Credo v1.7.7-rc.0)
Basics
This check is enabled by default.
Learn how to disable it via
.credo.exs
.
This check has a base priority of low
and works with any version of Elixir.
Explanation
Prefer using an implicit try
rather than explicit try
if you try to rescue
anything the function does.
For example, this:
def failing_function(first) do
try do
to_string(first)
rescue
_ -> :rescued
end
end
Can be rewritten without try
as below:
def failing_function(first) do
to_string(first)
rescue
_ -> :rescued
end
This emphazises that you really want to try/rescue anything the function does, which might be important for other contributors so they can reason about adding code to the function.
Like all Readability
issues, this one is not a technical concern.
But you can improve the odds of others reading and liking your code by making
it easier to follow.
