Flowsurface indicators

Optional .ind indicators for Flowsurface. Install these sources without rebuilding the application. The engine and bundled indicators remain in the application repository.

Each indicator is a .ind file defining its calculations and presentation. Its filename must match the final ID segment: alice.rsi goes in rsi.ind. Full IDs must be unique; matching filenames can coexist in separate folders. Folder names do not assign IDs.

Collection	IDs	License	Availability
Bundled	core.*	GPL-3.0-or-later	Included in Flowsurface
Catalog	catalog.*	Apache-2.0	Optional; install manually

Install and run

Use a build that includes scripted-indicator support. Copy the desired .ind files or folders from sources/ into <data-directory>/indicators/, then restart the app. The data directory is $FLOWSURFACE_DATA_PATH when set, otherwise the platform data directory's flowsurface/ folder. Flowsurface creates this directory at startup and searches subfolders, skipping symlinks.

For development, pass an explicit file (repeat the option for more files):

flowsurface --indicator-path /path/to/example.ind

Or, from a checkout of this catalog, use all sources with an installed application:

FLOWSURFACE_INDICATORS_PATH="$PWD/sources" flowsurface

Bundled indicators remain available when using either option.

Sources load once at startup. Invalid installed sources are skipped with diagnostics. Bundled IDs take precedence over installed duplicates; otherwise, the first installed source with an ID wins.

For authoring, see the language reference and CLI workflow. Run check and test before installing a source.

Catalog contributions

Add sources to sources/ using catalog.<name> IDs and <name>.ind filenames. See CONTRIBUTING.md for validation, Apache-2.0 licensing, and DCO sign-off requirements.
