README.md

Logic for transforming input records into output records as requested by the user (sort, filter, etc.).:

  • The IRecordTransformer abstract record-transformer interface datatype, as well as the ChainTransformer Go-channel chaining mechanism for piping one transformer into the next.
  • The transformer lookup table, used for Miller command-line parsing, verb construction, and online help.
  • All the concrete record-transformers such as cat, tac, sort, put, and so on.
