This section provides guidelines on creating CLI and GUI tools for Fuchsia.
For information on existing tools, please refer to documentation for those tools.
Packaging a tool with the core SDK
The core SDK will contain:
The tool binary itself.
The device-finder tool which can enumerate Fuchsia devices to get their names.
A document in //docs/development/sdk/documentation describing the contract of this tool and how to connect it to the target system. The target audience of this document is people writing integration scripts rather than being an end-user-friendly “how-to” (debugger example).
device-finder abstracts device listing and selection across all SDK
variants. With the right tool design, the extent of integration required should
be to run
device-finder to get the address and pass the address to the tool with
other environment-specific flags. In the case of the debugger the tool-specific
Connect to a shell (this should be a primitive provided by the environment-specific SDK) on the target and run the
Run zxdb with the address provided by
device-finder, passing any local settings files and symbol paths on the command-line.
Tools should allow all environment parameters to be passed in via command-line arguments. Examples include the location of settings files and symbol locations. This allows different SDKs to be hermetic.
Tools should be written to make writing environment-specific scripts as simple as possible. For example, the debugger should automatically retry connections (DX-1091) so the current behavior of waiting for the port to be open in the launch scripts can be removed.
Tool authors are responsible for:
- Writing the tool with the appropriate interface.
- Providing documentation on this interface in //docs/development/sdk/documentation.
- Currently please reach out to get bugs filed on individual SDKs. We are working on a better process for this (DX-1066).
