Typedef Documentation

◆ Path

typedef boost::filesystem::path Path

Typedef of a Path (shorter version for boost::filesystem::path)

◆ PathVector

typedef std::vector<Path> PathVector

Typedef for vector of Paths.

Function Documentation

◆ extractPaths()

PathVector mira::extractPaths ( const std::string & env )

Extracts and resolves all paths contained in an environment variable.

If the path is found and exists it will be added to the returned path list.

Parameters

[in] env The environmental variable e.g. PATH (without variable token like $ or %)

Returns: All the existing paths contained in the env variable

◆ normalizePath()

Path mira::normalizePath ( const Path & path )

Normalizes a path: it resolves all ".." in a path.

For optimal results the path should be made absolute before calling this function. Otherwise it is not guaranteed that all ".." are resolved e.g.

normalizePath("../my/path");

will return "../my/path" since it can not determine the parent path.

Note: This replaces boost::filesystem::path::normalize() because it is deprecated and also does not take symbolic links into account!

Parameters

[in] path The path to be normalized

Returns: The normalized path

◆ resolvePath()

Path mira::resolvePath	(	const Path &	path,
		bool	makeAbsolute = `true`
	)

Resolves a path.

It will resolve environment variables, (optionally) make the path absolute and finally normalized.

Parameters

[in]	path	The path to be resolved
[in]	makeAbsolute	If path is relative and this flag is set the path will be made absolute.

Returns: The resolved, absolute and normalized path

Note: for an empty input path, the relative result is empty, the absolute result is the same as for '.' (current working directory).

◆ isRootOfPath()

bool mira::isRootOfPath	(	const Path &	root,
		const Path &	path
	)

The function takes two absolute paths and returns true if the given root path is part of the path given in the path argument.

Parameters

[in]	root	path
[in]	path	to check

◆ getExecutableDirectory()

Path mira::getExecutableDirectory ( )

Get the path of the current running application binary.

Returns: The base of the current executable

◆ getHomeDirectory()

Path mira::getHomeDirectory ( )

Get the absolute path of the current user's home directory.

Under Linux this will be the content of the HOME environment variable.

Exceptions

XRuntime if no home directory can be found

Returns: The path of the current user's home directory

◆ getAppDataDirectory()

Path mira::getAppDataDirectory ( const std::string & appName = "mira" )

Returns the absolute path for application-specific data.

A sub-directory with the specified appName will be created automatically.

Under Linux the following directory will be returned: ${USER HOME}/.config/${appName}

Exceptions

XRuntime If the application data path does not exist or cannot be created.

Returns: The absolute path for application-specific data.

◆ getTempDirectory()

Path mira::getTempDirectory ( )

Get the absolute path of the temporary directory.

Under Linux the following checks are performed in the given order:

If TMPDIR is set its value is returned
If macro P_tmpdir is defined its value is returned
If /tmp exists it is returned

Exceptions

XRuntime if none of the above checks yields a result (meaning: no temporary directory can be found)

Returns: The path of the temporary directory

◆ relativizePath()

Path mira::relativizePath	(	const Path &	path,
		const Path &	base
	)

Returns relative path from base to path.

E.g.:

relativizePath("/home/user/mira/toolboxes", "/home/user/mira")

// returns toolboxes

◆ checkForMIRAPath()

void mira::checkForMIRAPath ( )

Checks if environment variable(s) for MIRA is/are defined.

Exceptions

Exception if variables is/are not set

◆ getMIRAPaths()

PathVector mira::getMIRAPaths ( )

Returns vector of all MIRA project paths.

Path mira::findFile	(	const PathVector &	paths,
		const Path &	file
	)

Find a file in a vector of paths.

Parameters

[in]	paths	The list of paths to search in.
[in]	file	The file to find.

If the file exists in different paths, the first occurrence will be returned. A sub directory structure can be given e.g.

findFile(paths, "resource/MyResourceFolder/Image.png")

Exceptions

Returns: The path to the found file.

◆ findFiles() [1/2]

PathVector mira::findFiles	(	const PathVector &	paths,
		const Path &	file,
		bool	recursive = `false`

Finds all files in a vector of paths.

Parameters

[in]	paths	The list of paths to search in.
[in]	file	The file (can also contain wildcards like * and ?)
[in]	recursive	Flag for recursive search.

A sub directory structure can be given within file e.g.

findFiles(paths, "resource/MyResourceFolder/Image*.png").

e.g. If paths=/usr/local/MIRA it will look for all files matching /usr/local/MIRA/resource/MyResourceFolder/Image*.png.

If recursive=true it will search (in the above example) for all occurrences of resource/MyResourceFolder/Image*.png in all sub directories of /usr/local/MIRA i.e. it will also find /usr/local/MIRA/AnotherFolder/SubFolder/resource/MyResourceFolder/Image1.png

Returns: All the found file paths.

◆ findFiles() [2/2]

PathVector mira::findFiles	(	const Path &	path,

		const Path &	path
	)

Find a sub directory in a vector of paths.

Parameters

[in]	paths	The list of paths to search in.
[in]	path	The sub path to find.

findDirectory(paths, "resource/MyResourceFolder/")

Exceptions

XIO	if no directory was found

Returns: The path to the found sub directory.

◆ findProjectDirectory()

Path mira::findProjectDirectory ( const Path & path )

Same as findDirectory above, but using all of the paths contained in $MIRA_PATH variable.

◆ findContainingMIRAPath() [1/4]

Path mira::findContainingMIRAPath ( const Path & path )

Returns the MIRA path that contains the given path.

Parameters

[in] path the path to be processed

Returns: the mira path that contains the given path

Exceptions

XLogical if path is not located in one of the MIRA paths

◆ chopMIRAPath() [1/4]

Path mira::chopMIRAPath ( const Path & path )

Removes the root part of the given path that belongs to one of MIRA paths.

E.g.:

chopMIRAPath('/home/user/mira/some/sub/folder')

will return 'some/sub/folder' if '/home/user/mira' is set as MIRA path.

Parameters

[in] path the path to be processed

Returns: the relative path from the containing mira folder to the given path

Exceptions

XLogical if path is not located in one of the MIRA paths

◆ findDirectories() [1/2]

PathVector mira::findDirectories	(	const PathVector &	paths,
		const Path &	path,
		bool	recursive = `false`
	)

Finds all sub directories in a vector of paths.

Parameters

[in]	paths	The list of paths to search in.
[in]	path	The sub path to find.
[in]	recursive	Flag for recursive search.

A sub directory structure can be given e.g.

e.g. If paths=[/usr/local/MyProject, /usr/local/AnotherProject] it will look for all occurrences of resource/MyResourceFolder/ in /usr/local/MyProject/ and /usr/local/AnotherProject.

if recursive = true it will also search for all occurrences of resource/MyResourceFolder/ in all sub directories of /usr/local/MyProject and /usr/local/AnotherProject i.e. it will also find /usr/local/MyProject/AnotherFolder/SubFolder/resource/MyResourceFolder/
if recursive = false it will only find all directories that match the combination of paths[X]/path e.g. in the above example it would find exactly 2 directories /usr/local/MyProject/resource/MyResourceFolder/ and /usr/local/AnotherProject/resource/MyResourceFolder/

Returns: All the found directories.

◆ findDirectories() [2/2]

PathVector mira::findDirectories	(	const Path &	basePath,

Same as findDirectories above, but searching only in one path.

◆ findProjectDirectories()

PathVector mira::findProjectDirectories	(	const Path &	path,
		bool	recursive = `false`
	)

Same as findDirectories above, but using all of the paths contained in $MIRA_PATH variable.

◆ findProjectPath()

std::string mira::findProjectPath ( const std::string & path )

Finds a file or directory searching in all paths contained in $MIRA_PATH.

3. findProjectFiles recursively in all subdirs, if no file found
4. findProjectDirectories recursively in all subdirs
Exceptions

XIO If no file or directory is found or multiple matches are found

Parameters

path The path to be found

Returns
The found file or directory

◆ findContainingMIRAPath() [2/4]

constexpr std::string_view mira::findContainingMIRAPath	(	const std::string_view &	path,
		const std::string_view &	miraPaths
	)

Returns the MIRA path that contains the given path.

Parameters

[in]	path	the path to be processed
[in]	miraPaths	the MIRA paths

Returns: the mira path that contains the given path, or "" if none

The option to provide MIRA paths as argument is useful for testing. See below for an overload that does not require this.

◆ findContainingMIRAPath() [3/4]

constexpr std::string_view mira::findContainingMIRAPath	(	const char *	path,
		const char *	miraPaths
	)

As above, overload for const char* path.

Note that you cannot just convert the result to a const char*, as the size is needed in addition to the data pointer (matching null-termination can not be assumed)!

◆ findContainingMIRAPath() [4/4]

constexpr std::string_view mira::findContainingMIRAPath ( const char * path )

With this overload the MIRA paths are not provided as argument, they are expected to be defined as a compiler definition MIRA_PATHS.

Otherwise this will return an empty string literal "".

Note that you cannot just convert the result to a const char*, as the size is needed in addition to the data pointer (matching null-termination can not be assumed)!

◆ chopMIRAPath() [2/4]

constexpr std::string_view mira::chopMIRAPath	(	const std::string_view &	path,
		const std::string_view &	miraPaths
	)

Removes the root part of the given path that belongs to one of MIRA paths.

E.g.:

chopMIRAPath('/home/user/mira/some/sub/folder')

will return 'some/sub/folder' if '/home/user/mira' is set as MIRA path.

Parameters

[in]	path	the path to be processed
[in]	miraPaths	the MIRA paths

Returns: the relative path from the containing MIRA folder to the given path, or just the given path if it is not within a MIRA path

The option to provide MIRA paths as argument is useful for testing. See below for an overload that does not require this.

◆ chopMIRAPath() [3/4]

constexpr const char* mira::chopMIRAPath	(	const char *	path,
		const char *	miraPaths
	)

As above, overload for const char* path.

As this only removes prefixes from path, null-termination persists and it is safe to return a const char*

◆ chopMIRAPath() [4/4]

constexpr const char* mira::chopMIRAPath ( const char * path )

With this overload the MIRA paths are not provided as argument, they are expected to be defined as a compiler definition MIRA_PATHS.

Otherwise this will return the unchanged argument path.

As this only removes prefixes from path, null-termination persists and it is safe to return a const char*
