Commands¶

minisky inherits much of BlueSky's stack command language (a text-based domain-specific language (DSL)), but makes some tweaks, most notably the requirement to specify explicit units.

This DSL is used by scenario files (.scn) and the interactive console, for example:

Interactive consoleScenario file (.scn)Python

minisky console

> CRE KL001 B738 52 4 90 FL100 250KT[CAS]
> KL001 ALT FL200
> POS KL001

To run commands at a specified simulation time, specify a timestamp for each command:

example.scn

00:00:00.00> CRE KL001 B738 52 4 90 FL100 250KT[CAS]
00:00:00.00> KL001 ADDWPT HELEN FL100 250KT[CAS]
00:00:10.00> KL001 ALT FL200
00:30:00.00> QUIT

Run with:

minisky run --scenario example.scn --speed 10

Here, --speed 10 changes how quickly simulation time is paced against wall-clock time (see basics for more information).

runtime.commands.stack("KL001 ALT FL200")
runtime.simulation.step()

See the complete stack command reference for all supported commands. If you are a plugin developer, see the guide on adding commands.

Warning

We strongly recommend using the typed MiniSky Python API instead of the DSL, so mistakes can be caught by static type checkers (e.g. pyright) instead of at runtime. The Python API is also usually much easier to work with.
