Euler Scraper

Euler Scraper is a command-line tool for scraping problem content from Project Euler and saving it to local files.

Usage

go run main.go -p <problem_number> [-r <problem_number_end>] [-f <folder_path>] [-c <config_file_path>]

The tool supports the following command-line flags:

• -p <problem_number>: Specifies the problem number to scrape from Project Euler. This flag is required.
• -r <problem_number_end>: Specifies the range of problem numbers to scrape from Project Euler.
• -f <folder_path>: Specifies the folder path where the scraped content will be saved. If not provided, the current directory will be used.
• -c <config_file_path>: Specifies the path to a YAML config file that defines the programming languages and their corresponding file extensions. If not provided, the tool will use a default configuration.

Configuration File

The optional configuration file allows you to define the programming languages and their corresponding file extensions. The file should be in YAML format and have the following structure:

fileName: name
folderName: name
programmingLanguages:
  language1: extension1
  language2: extension2
  ...

For example:

fileName: solution
folderName: solutions
programmingLanguages:
  golang: go
  python: py
  ruby: rb

When the configuration file is provided, the tool will create solution files in the specified programming languages based on the defined extensions.

Examples

Scrape problem 1 and save the content to the current directory:

go run main.go -p 1

Scrape problem 1 and save the content to a specific folder:

go run main.go -p 1 -f /path/to/folder

Scrape problem 1 and use a custom configuration file:

go run main.go -p 1 -c /path/to/config.yaml

Dependencies

The tool relies on the following external package:

• gopkg.in/yaml.v2: A YAML parser for Go. You can install it using the command go get gopkg.in/yaml.v2.
