datumhue

command
datumhue [OPTIONS] [-- <SCRIPT_ARGS>...] [COMMAND]

DatumHue Creative Workstation.

ArgumentDefaultDescription
[SCRIPT_ARGS]...none

Tokens forwarded to the launched script via datumhue.args.argv

OptionDefaultDescription
--bootstrap <NAME>none

Bootstrap package to launch. Falls back to DATUMHUE_BOOTSTRAP_PACKAGE

--aggregator-url <URL>none

Aggregator base URL of the deployment to contact (e.g. https://aggregator.example.com). Networked commands require it unless running --offline.

Accepted by every subcommand.

env DATUMHUE_AGGREGATOR_URL

--namespace <NAME>none

Catalog namespace to bootstrap from. The bootstrap package and datumhue.packages queries resolve against this namespace. Falls back to DATUMHUE_BOOTSTRAP_NAMESPACE, then datumhue.

--session <NAME>none

Session id for this launch, which its apps read as datumhue.app.session. Wins over --continue

--continueoff

Take the most recent launch's session id again, if there is one

--offlineoff

Run without contacting any DatumHue deployment. It needs an earlier launch on this device that reached the deployment, and runs until the license term the latest such launch received ends. Sign-in, the package catalog, mounts, and network-scope messages and documents are unavailable; everything else works. DATUMHUE_OFFLINE=1 (or true, yes, on) does the same.

Accepted by every subcommand.

--headlessoff

Run without a window; nothing is drawn. The launched package must be a service app; a UI app is refused

--debug-inputoff

Allow datumhue.debug.input for this launch even though the package arrives from the deployment. Local scripts and package directories allow it without this flag

--plugins-dir <DIR>none

Directory of native plugins to load at startup. Each shared library in it extends the Lua API with native code that can do anything DatumHue can, so keep only libraries you trust there

env DATUMHUE_PLUGINS_DIR

--dir <NAME:PATH>none

Grant a read-only directory capability (NAME:PATH)

--dir-rw <NAME:PATH>none

Grant a read-write directory capability (NAME:PATH)

--file <NAME:PATH>none

Grant a read-only file capability (NAME:PATH)

--file-rw <NAME:PATH>none

Grant a read-write file capability (NAME:PATH)

--remote-dir <NAME:MOUNT>none

Grant a read-only directory capability on one of the deployment's filesystem mounts (NAME:MOUNT). The script reaches the directory as datumhue.args.dirs.<name>

--remote-dir-rw <NAME:MOUNT>none

Grant a read-write directory capability on one of the deployment's filesystem mounts (NAME:MOUNT)

--data-mount <NAME:MOUNT>none

Grant a read-only data mount capability (NAME:MOUNT). The script reaches the mount as datumhue.args.data_mounts.<name> and runs SQL queries via mount:query(sql)

--data-mount-rw <NAME:MOUNT>none

Grant a read-write data mount capability (NAME:MOUNT)

--http-mount <NAME:MOUNT>none

Grant an HTTP mount capability (NAME:MOUNT). The script reaches it as datumhue.args.http_mounts.<name> and makes requests via mount:get(path) / mount:post(path, opts) etc

--ingress-mount <NAME:MOUNT>none

Grant an ingress mount capability (NAME:MOUNT). The script reaches it as datumhue.args.ingress_mounts.<name> and subscribes to its channel via mount:subscribe({callback = ...})

Environment 8

VariableDescription
BROWSER

Commands that open web pages (http and https addresses), separated by ':' (';' on Windows) and tried in order until one starts. Each is split at spaces as a shell splits it (quotes keep a path with spaces together) and run without a shell; '%s' stands for the address, else the address is appended. Unset or empty: the system's default browser. When it is set and none of its commands starts, the page does not open: the system's default browser is not tried in its place. A command runs apart from the terminal, so a text-mode browser such as w3m or lynx cannot show the page (to sign in from a terminal, run datumhue login --no-browser). Other addresses always open in the system's default application.

DATUMHUE_ACCESS_KEY

The deployment's access key, from its datumhue-client.env. Every command that contacts the deployment takes it; --offline runs without it once a launch on this device has reached the deployment, until the license term the latest such launch received ends.

DATUMHUE_AGGREGATOR_URL

Supplies datumhue --aggregator-url when it is not given.

DATUMHUE_BOOTSTRAP_NAMESPACE

Supplies datumhue pkg update --namespace, datumhue pkg push --namespace, datumhue pkg search --namespace, datumhue pkg show --namespace, datumhue pkg yank --namespace, datumhue pkg dependents --namespace and datumhue pkg outdated --namespace when they are not given.

DATUMHUE_BOOTSTRAP_PACKAGE

Bootstrap package to launch when --bootstrap is not passed.

DATUMHUE_CERT_PATH

Extra CA certificates (PEM) to trust when contacting the deployment, besides the public ones.

DATUMHUE_OFFLINE

1 / true / yes / on is equivalent to passing --offline.

DATUMHUE_PLUGINS_DIR

Supplies datumhue --plugins-dir when it is not given.
