The command "pycodestyle --first ${file-py}" is used to run the pycodestyle tool with some specific options and parameters. Here's a breakdown of the command:
-
"pycodestyle" is the name of the command-line tool that performs style checking on Python code. It checks the code against the PEP 8 style guide.
-
"--first" is an option or flag that tells pycodestyle to only report the first occurrence of each error. This can be useful if you have multiple occurrences of the same error and you only want to see the first one.
-
"${file-py}" is a placeholder or variable that should be replaced with the actual Python file you want to check. The "${file-py}" notation suggests that the value should be provided as an argument or parameter when executing the command. For example, if you want to check a file named "script.py", you would replace "${file-py}" with "script.py" when running the command.
Overall, the command "pycodestyle --first ${file-py}" is used to check a Python file for style violations using the pycodestyle tool, and it only reports the first occurrence of each error.
