Documentation for TmpDir wrong

[pixelbrackets]

Steps to reproduce

Install Robo 1.2.2
Execute example code from https://github.com/consolidation/Robo/blob/master/docs/tasks/Filesystem.md#tmpdir

Expected behavior

Create a temporary directory.

Actual behavior

PHP Fatal error:  Uncaught Error: Call to a member function getPath() on string in RoboFile.php

System Configuration

PHP 7, Ubuntu 16.04, Robo 1.2.2

Reason

The documentation mixes configuration for taskTmpDirwith building a collection. The collection builder however returns not the temp-dir object, but the path string instead. See https://github.com/consolidation/Robo/blob/master/src/Collection/CollectionBuilder.php#L134

Solution

Remove ->getPath()in the example code. Add another example for the taskTmpDir task (since all other tasks on the same page are documented like this as well).

If you agree with the solution I could send a PR.

Thanks a lot @pixelbrackets for this comment, either after so many years that comment helped me a lot to solve this error.
could not find this comment somewhere else and still is not updated in the Docs. So sad that they did not fix that.
