While they serve different purposes, you can definitely use them together to achieve better results. Here’s how:
1. Install Prospector using pip:
# This script installs Prospector using pip, a package manager for Python
# The command "pip install" is used to install packages from the Python Package Index (PyPI)
# The package "prospector" is being installed
# To use this script, you must have pip installed on your system
# If you do not have pip installed, you can install it using the command "sudo apt install python3-pip"
# To install Prospector, run the following command in your terminal:
# bash install_prospector.sh
#!/bin/bash
# This line specifies the interpreter to be used for executing the script
pip install prospector
# This line uses pip to install the package "prospector" from PyPI
2. Create a `prospectors.ini` file in the root directory of your project with the following content:
; This is a comment, it is used to provide additional information and is not read by the program.
; The [prospector] section is used to define the settings for the prospector tool.
[prospector]
; The reports setting specifies the types of reports that will be generated by the prospector tool.
; In this case, the checkstyle, pylint, and flake8 reports will be generated.
reports = checkstyle, pylint, flake8
; The checkstyle_config setting specifies the location of the checkstyle configuration file.
; In this case, the file is located in the .checkstyle directory in the root directory of the project.
checkstyle_config = ./.checkstyle/checkstyle.xml
; The pylint_args setting specifies additional arguments to be passed to the pylint tool.
; In this case, the arguments disable certain pylint checks for code style and conventions.
pylint_args = --disable=C0103,R0904,W0621,W0703
; The flake8_ignore setting specifies which flake8 errors and warnings should be ignored.
; In this case, the E501, E203, F401, F403, and W503 errors and warnings will be ignored.
flake8_ignore = E501,E203,F401,F403,W503
This configuration will run Prospector with three different reports: checkstyle (for code style), pylint (for linter checks) and flake8 (for PEP 8 compliance). You can customize the arguments for each report as needed.
3. Create a `checkstyle.xml` file in your project’s root directory with the following content:
xml
<!-- This is an XML script that will run Prospector with three different reports: checkstyle (for code style), pylint (for linter checks), and flake8 (for PEP 8 compliance). You can customize the arguments for each report as needed. -->
<!-- This line specifies the version and encoding of the XML document. -->
<?xml version="1.0" encoding="UTF-8"?>
<!-- This line specifies the document type and its public identifier. -->
<!DOCTYPE module PUBLIC "-//Puppet Labs//DTD Check Configuration 1.2.0//EN" "http://puppetlabs.com/checkstyle/dtds/configuration.dtd">
<!-- This is the root element of the document, which contains the configuration for running Prospector with Python. -->
<module name="prospector-python">
<!-- This property sets the severity level for the reports to "warning". -->
<property name="severity" value="warning"/>
<!-- This property specifies the source files to be checked, using the wildcard "*.py". -->
<property name="sourcefilesag" value="*.py"/>
<!-- This property specifies the configuration file to be used, "./prospectors.ini". -->
<property name="config" value="./prospectors.ini"/>
</module>
This configuration will run Prospector with the `checkstyle` report and use your project’s `prospectors.ini` file for configuration.
4. Run Prospector using the following command:
bash
# This script runs Prospector with the `checkstyle` report and uses the project's `prospectors.ini` file for configuration.
# Set the configuration file to `prospectors.ini`
prospector --config-file=prospectors.ini
# Run Prospector on the current directory
prospector .
# The above command will generate a `checkstyle` report for the project's code quality.
Prospector will analyze all of the Python files in your project and generate reports based on the configured rulesets.
5. Install isort using pip:
# This script installs the isort package using pip
# Install pip if not already installed
# -q flag suppresses output
# -H flag sets the cache directory
# -m flag ensures that the main module is run
# get-pip.py is a script that downloads and installs pip
python -m ensurepip -q -H /tmp
# Upgrade pip to the latest version
# -q flag suppresses output
# -H flag sets the cache directory
# -U flag upgrades pip to the latest version
python -m pip install -q -H /tmp -U pip
# Install isort using pip
# -q flag suppresses output
# -H flag sets the cache directory
# isort is the package being installed
pip install -q -H /tmp isort
6. Run isort to sort your import statements alphabetically:
# This script runs the isort command to sort import statements alphabetically and checks for any errors.
isort . --check-only
# The "." indicates that the command will be run on the current directory.
# The "--check-only" flag ensures that the command only checks for errors and does not make any changes to the files.
# This is useful for testing the script before actually making any changes to the files.
This will run isort in check mode, which means it won’t actually modify any files but instead prints out the changes that would be made if you ran `–diff`. This can help you review the changes before committing them.
7. Run isort again to apply the changes:
# This script runs isort in check mode, which means it won't actually modify any files but instead prints out the changes that would be made if you ran `--diff`.
# This can help you review the changes before committing them.
# Run isort again to apply the changes:
isort . --recursive --diff --check # Corrected "recurs" to "recursive" for proper flag usage
# Added "--recursive" flag to ensure all subdirectories are included in the sorting process
# Removed extra space between "--recurs" and "--diff" for consistency
# Removed extra space between "--diff" and "--check" for consistency
# Added comment to explain the purpose of the script and the use of check mode
# Added comment to explain the purpose of the second run of isort
# Added comment to explain the use of "--recursive" flag
# Added comment to explain the purpose of "--diff" and "--check" flags
# Removed unnecessary period at the end of the script
This will run isort in diff mode, which means it prints out the changes that would be made if you ran `–diff`. This can help you review the changes before committing them. If everything looks good, you can then apply the changes using the `–recurs` option to sort all of your import statements recursively.
By combining Prospector and isort together in this way, you’ll be able to achieve better code formatting results by running both tools simultaneously. This will help ensure that your code follows best practices for style, linting, and PEP 8 compliance while also sorting your import statements alphabetically.
