Classic dropfile doors · foglet docs

Classic dropfile doors are external programs that expect old BBS metadata files before launch. Foglet can generate a fixed set of classic files from safe session metadata, write them into the runner-owned launch directory, and remove them during cleanup.

Supported formats

chain_txt writes CHAIN.TXT.
door_sys writes DOOR.SYS.
door32_sys writes DOOR32.SYS.
dorinfo_def writes DORINFO.DEF.

Rendered files use CRLF line endings. File layouts are owned by Foglet's renderer modules. Manifests declare formats; they cannot choose filenames or arbitrary paths.

Manifest shape

Use runtime: "classic_dropfile", set absolute command and working_dir, then declare either:

"dropfile_formats": ["door_sys", "dorinfo_def"]

or detailed entries:

"dropfiles": [
  {"format": "door_sys", "encoding": "cp437", "expose_path": "env"}
]

When expose_path is env, Foglet sets format-specific variables such as FOGLET_DROPFILE_DOOR_SYS plus FOGLET_DROPFILE_DIR.

Compatibility warning

Classic compatibility is per-door work. Some old games assume DOS paths, node files, fossil drivers, local screen modes, or writable install directories. Foglet provides dropfiles and a terminal bridge; it does not emulate a 1990s host.
