go

Command api is the M7 end-to-end guest: a Go program that calls the Factorio API through the generated bindings.

Command array exercises the variable-length marshalling: arrays over every element shape, dictionaries, and tier-2 dynamic values, in both directions.

Command callback exercises the callback seam in both directions: a console command and a remote interface this guest declares, and a remote.call it makes into somebody else's.

Command callcost is the fixture for profiling what a host call costs through a REAL compiled guest, rather than through the Lua ABI on its own.

Command churn is the allocation-churn guest: what an ORDINARY allocating Go event handler costs a guest that cannot collect.

Command confchanged is the in-game fixture for the CONFIGURATION-CHANGED PAYLOAD: what script.on_configuration_changed hands its handler, which the FkLua hook discarded for two milestones.

Command custominput is the in-game fixture for a NAME-ADDRESSED subscription, which is how Factorio delivers a keybind.

Command custominputdata is the DATA-STAGE half of the custom-input fixture: it defines the two custom-input prototypes ./examples/custominput subscribes to by name.

Command datastage is the data-stage end-to-end guest: a Go program that becomes a Factorio mod's settings.lua, data.lua and data-final-fixes.lua.

Command demo-daylight is half of the two-mod fkipc demo: a slider in a web page drags the sun across a running Factorio.

Command dict is the end-to-end fixture for a DICTIONARY FIELD INSIDE A STRUCT, which is the shape five event payloads carry and the Go generator refused until 2026-08-02 -- and, since 2026-08-06, for A BINARY STRING through a generated reader.

Command dynread is the end-to-end fixture for READING a tier-2 value.

Command eventheap measures how much guest heap a HOST-INITIATED dispatch keeps forever.

Command gcbench is the acceptance vehicle for what a collection costs the WORST TICK, in a real Factorio, measured by Factorio.

Command gcconfig asks one question of the collector: does the configuration a guest installs BEFORE THE COLLECTOR COMES UP survive?

Command gcsave is the collector's save/load guest: does a heap that is being COLLECTED survive a real Factorio save and reload?

Command gctorture is the collector's retention gate: build a structure, drop a KNOWN half of it, collect, and check that what should have survived did and what should not have did not.

Command goroutine is the M10 guest: a Go program using goroutines and channels, compiled to Lua and run inside Factorio's sandbox.

Command grow is the round-trip's growing guest.

Command growbench is the acceptance vehicle for what a `memory.grow` costs the WORST TICK, in a real Factorio, measured by Factorio.

Command heap measures how much guest heap a host call keeps forever.

Command hello is the M4 end-to-end guest: a Go program that becomes a Factorio mod.

Command ipc is the fkipc wiring fixture: the four lines a guest author writes to get an IPC link, and nothing else.

Command lasterror is the fixture for fk.LastError, the import that carries WHAT THE ENGINE SAID across the boundary beside a status.

Command logdump is the end-to-end fixture for the LINE BUILDER and the VALUE DUMPER, which are the two halves of one story: a guest that wants to say what it is doing without paying for it forever.

Command migrate is the round-trip's REBUILD guest: the only one here that exports fk_migrate, and the reason it exists is that nothing ever had.

Command retain is the round-trip's PERSISTENT HANDLE guest.

Command typedargs is the end-to-end fixture for the TYPED ARGUMENT form of a method whose parameter table is a discriminated union.

Package wire is the fkipc frame codec: the 24-byte header, the nine frame types, and the four control payloads both ends must agree on byte for byte.
