Function Documentation

fetchResource()

std::string gz::fuel_tools::fetchResource

(

const std::string &

_uri

)

Download the specified resource into the default configuration of fuel tools. This will place the asset in ~/.gz/fuel.

Parameters

[in]

_uri

URI to the asset.

Returns

Path to the downloaded asset. Empty on error.

fetchResourceWithClient()

std::string gz::fuel_tools::fetchResourceWithClient	(	const std::string &	_uri,
		FuelClient &	_client
	)

Download the specified resource using the ClientConfig contained in the FuelClient parameter.

Parameters

[in]	_uri	URI to the asset.
[in]	_client	Custom FuelClient configuration.

Returns

Path to the downloaded asset. Empty on error.

sdfFromPath()

std::string gz::fuel_tools::sdfFromPath

(

const std::string &

_path

)

Get the SDF file path for a model or world based on a directory containing a Fuel model or world. Here is a typical use case:

1. Fetch a Fuel resource: std::string resourcePath = fetchResource("https://...")
2. Get the SDF file for the resource: std::string resourceSdf = sdfFromPath(resourcePath)
3. Parse the SDF file using libsdformat.

This function will determine the SDF file according to the following:

1. Check for a metadata.pbtxt file, and return the SDF file specified within the metadata.pbtxt file.
2. Check for a model.config file, and return the SDF file specified withing the model.config file.
3. Return the first file with an .sdf extension.

   Parameters

   [in]

   _path

   Filesystem path to a Fuel model or world directory.

   Returns

   Full path to the model or world SDF file, or empty string if the SDF file coult not be determined.

uriToPath()

std::string gz::fuel_tools::uriToPath

(

const gz::common::URI &

_uri

)

Convert a URI to a string suitable to use as a path on disk. It strips the scheme and authority's // prefix.

Parameters

[in]

_uri

URI to convert.

Returns

String suitable to use in file paths
