Detailed Description

Paths to configuration / shared data directories.

The functions in Paths provide a portable access to the paths of useful directories that may depend on the site or user configuration, or on environment variables (such as BRAINVISA_SHARE or HOME ).

Path is implemented as a namespace rather than a class with static methods so that it can easily be extended in upper-level libraries.

Function Documentation

addResourceSearchPath()

void carto::Paths::addResourceSearchPath	(	const std::string &	path,
		bool	atbeginning = false
	)

argv0()

const std::string& carto::Paths::argv0

(

)

argv[0], ie executable name and path; only available when a CartoApplication has been built

findResourceFile()

std::string carto::Paths::findResourceFile	(	const std::string &	filename,
		const std::string &	project = "",
		const std::string &	version = ""
	)

Find a file in the shared resources directories, or in a personal directory.

Files are looked in the search paths given by resourceSearchPath(). For each search path, the filename is looked in a subdirectory containing the project name and version (if not specified, cartobase version is used), and then in a subdirectory containing the project name without version. For personal directories, a dot may be prepended to the project name for use as a hidden directory (classical on Unix), like "/home/user/.anatomist/..." The function stops at the first match and return the first path.

findResourceFiles()

std::list<std::string> carto::Paths::findResourceFiles	(	const std::string &	filename,
		const std::string &	project = "",
		const std::string &	version = ""
	)

Same as findResourceFile() except that it looks for every occurrence of the searched file (or directory).

globalShared()

const std::string& carto::Paths::globalShared

(

)

The base shared directory for all cartograph / SHFJ data.

home()

const std::string& carto::Paths::home

(

)

User home directory.

memmap()

const std::string& carto::Paths::memmap

(

)

Temporary directory used for memory mapping with copy - this directory has better be large.

resourceSearchPath()

const std::list<std::string>& carto::Paths::resourceSearchPath

(

)

Shared resource files search path.

It typically includes:

• home() + "/.brainvisa";
• home();
• globalShared()

setArgv0()

void carto::Paths::setArgv0

(

const std::string &

argv0

)

shfjShared()

const std::string& carto::Paths::shfjShared

(

)

Shared directory for SHFJ-specific data.

Depending on the installation and configuration, this may be the same as the globalShared() directory.

tempDir()

const std::string& carto::Paths::tempDir

(

)

Temporary directory used for general usage.
