Configuration

Credentials and cache locations are centralized in getscipapers_hoanganhduc.configuration. Key points:

Credential Sources

• Environment variables such as CROSSREF_EMAIL and UNPAYWALL_EMAIL can be provided to avoid interactive prompts.

• JSON files at ~/.config/getscipapers/credentials.json (Linux/macOS) or %APPDATA%/getscipapers/credentials.json (Windows) are loaded when present.

• The --non-interactive flag forces the CLI to abort if credentials are missing instead of prompting for input.

Cache and Download Directories

• The default cache directory is derived from the operating system and can be inspected via configuration.get_cache_dir().

• Download targets default to ~/Downloads/getscipapers but can be overridden with the --download-dir flag in getpapers.

Token Management

API keys for Elsevier and Wiley can be set via environment variables or saved to credentials files. The refresh helpers in configuration ensure these tokens are reloaded each time a request is made rather than captured at import time.
