module MediaFilter

Defined in:

utils/media_filter.cr

Constant Summary

MAX_FILE_SIZE = begin if size_str = ENV["NOIR_MAX_FILE_SIZE"]? parsed = MediaFilter.parse_size(size_str) parsed > 0 ? parsed : (10 * 1024) * 1024 else (10 * 1024) * 1024 end rescue (10 * 1024) * 1024 end

Maximum file size for processing (default 10MB). Can be overridden with the environment variable NOIR_MAX_FILE_SIZE. Supported formats for NOIR_MAX_FILE_SIZE:

  • Plain bytes integer (e.g., 5242880)
  • Human-readable with unit suffix (K, KB, M, MB, G, GB) e.g., 5MB, 500K, 1G Invalid / unparsable values fall back to the default (10MB).
