+# To configure PyLint as an external tool in PyCharm, create a new External Tool with the settings:
+#
+# Name: PyLint
+# Program: Check with 'which pylint'. For example: ~/.local/bin/pylint
+# Arguments: $FileDirName$ --rcfile=.pylintrc --msg-template='{abspath}:{line}:{column}:({symbol}):{msg_id}:{msg}'
+# Working directory: $ContentRoot$
+# Output filters: $FILE_PATH$:$LINE$:$COLUMN$:.*
+#
+# You can add a keyboard shortcut in the keymap settings. To run Pylint to a project, select the module
+# you want to check (e.g. cura folder) before running the external tool.
+#
+# If you find a better way to configure the external tool please edit this file.

+# C0413: Ignore import order because the rules are different than in PyCharm, so automatic imports break lots of builds

+# R1710: Either all return statements in a function should return an expression, or none of them should.
+# W0221: Parameters differ from overridden method (tornado http methods have a flexible number of parameters)

+# C0111: We don't use docstring
+# C0303: Trailing whitespace isn't something we care about
