Credo v1.4.0 Credo.Check.Warning.UnusedPathOperation View Source
This check has a base priority of high and works with any version of Elixir.
Explanation
The result of a call to the Path module's functions has to be used.
While this is correct ...
def read_from_cwd(filename) do
filename = Path.join(cwd, filename)
File.read(filename)
end... we forgot to save the result in this example:
def read_from_cwd(filename) do
Path.join(cwd, filename)
File.read(filename)
endPath operations never work on the variable you pass in, but return a new variable which has to be used somehow.
Configuration parameters
There are no parameters for this check.
