Usage

blech [OPTIONS] <BASE_URL>

Positional Arguments:

• <BASE_URL>: (Required) The starting URL of the blog's main page, index, or feed where post links can be found.

Options:

• -o, --output <FILENAME>: (Optional) The file where extracted content should be saved. If not provided, a default filename will be generated based on the blog's domain (e.g., example-blog.com_blog_posts.txt).
• -l, --lang <LANG_CODE>: (Optional) Filter posts by language code (e.g., 'en', 'fi'). This primarily works when the blog uses a WordPress REST API that supports language filtering.
• --one-file: (Optional) Save all blog posts to a single file instead of separate files. By default, each post is saved as a separate file in a directory named based on the output filename without the .txt extension (e.g., example-blog.com_blog_posts).
• -h, --help: (Optional) Show this help message and exit.

Example:

# Scrape English posts from the blog archive and save to a specific file
poetry run blech --output my_blog_extract.txt --lang en https://example-blog.com/archive

# Scrape all posts and use the default filename
poetry run blech https://another-blog.org/

# Scrape posts and save each one as a separate file in a directory (default behavior)
poetry run blech https://example-blog.com/

# Scrape posts, specify output directory name, and save as separate files
poetry run blech --output custom_dir_name.txt https://example-blog.com/

# Scrape posts and save all to a single file
poetry run blech --one-file https://example-blog.com/

# Scrape posts, specify output filename, and save to a single file
poetry run blech --output custom_file_name.txt --one-file https://example-blog.com/
