Receiver data often arrives as compact codes. Looking up the same unfamiliar value repeatedly interrupts an investigation. squawk-decoder packages reference information for Mode A squawks, emitter categories, and ICAO aircraft types in a tool that can work offline.
Keep reference close to the work
Bundled data makes ordinary lookups available without a network request. Known flags and descriptions provide context while inspecting decoder output or building another tool. The benefit is convenience and consistency, rather than turning a code lookup into a comprehensive interpretation of a flight.
Watch only when requested
An explicit watch mode can follow changes from a live source. Establishing a baseline helps distinguish later changes from the values already present at startup. Keeping watching separate from ordinary offline lookup makes the tool's behavior easier to predict.
Use descriptions with care
Codes and categories provide limited context. A reference entry is not an instruction from air traffic control, a verified explanation of an aircraft's situation, or a basis for operational decisions. Consult the repository for the bundled reference scope, supported lookups, and watch-mode configuration.
