NormalizePath() [1/2]

wxString NormalizePath	(	const wxFileName &	aFilePath,
		const ENV_VAR_MAP *	aEnvVars,
		const PROJECT *	aProject
	)

Normalize a file path to an environmental variable, if possible.

Parameters

aFilePath	is the full file path (path and file name) to be normalized.
aEnvVars	is an optional map of environmental variables to try substitution with.
aProject	is an optional project, to normalize the file path to the project path.

Returns

Normalized full file path (path and file name) if succeeded or the input path if the path could not be normalized.

{
 if( aProject )
 return NormalizePath( aFilePath, aEnvVars, aProject->GetProjectPath() );
 else
 return NormalizePath( aFilePath, aEnvVars, "" );

NormalizePath() [2/2]

wxString NormalizePath	(	const wxFileName &	aFilePath,
		const ENV_VAR_MAP *	aEnvVars,
		const wxString &	aProjectPath
	)

Normalize a file path to an environmental variable, if possible.

Parameters

aFilePath	is the full file path (path and file name) to be normalized.
aEnvVars	is an optional map of environmental variables to try substitution with.
aProjectPath	is an optional string to normalize the file path to the project path.

Returns

Normalized full file path (path and file name) if succeeded or the input path if the path could not be normalized.

ResolveFile()

wxString ResolveFile	(	const wxString &	aFileName,
		const ENV_VAR_MAP *	aEnvVars,
		const PROJECT *	aProject
	)

Search the default paths trying to find one with the requested file.

Parameters

aFileName	is the name of the searched file. It might be a relative path.
aEnvVars	is an optional map of environmental variables that can contain paths.
aProject	is an optional project, to check the project path.

Returns

Full path (apth and file name) if the file was found in one of the paths, otherwise an empty string.
