PathBuf#

Added in version 2.76.

class PathBuf(*args, **kwargs)#

GPathBuf is a helper type that allows you to easily build paths from individual elements, using the platform specific conventions for path separators.

g_auto (GPathBuf) path;

g_path_buf_init (&path);

g_path_buf_push (&path, "usr");
g_path_buf_push (&path, "bin");
g_path_buf_push (&path, "echo");

g_autofree char *echo = g_path_buf_to_path (&path);
g_assert_cmpstr (echo, ==, "/usr/bin/echo");

You can also load a full path and then operate on its components:

g_auto (GPathBuf) path;

g_path_buf_init_from_path (&path, "/usr/bin/echo");

g_path_buf_pop (&path);
g_path_buf_push (&path, "sh");

g_autofree char *sh = g_path_buf_to_path (&path);
g_assert_cmpstr (sh, ==, "/usr/bin/sh");

Methods#

class PathBuf

clear() → None#

Clears the contents of the path buffer.

This function should be use to free the resources in a stack-allocated GPathBuf initialized using init() or init_from_path().

Added in version 2.76.

clear_to_path() → str | None#

Clears the contents of the path buffer and returns the built path.

This function returns NULL if the GPathBuf is empty.

See also: to_path()

Added in version 2.76.

init() → PathBuf#: Initializes a GPathBuf instance.

Added in version 2.76.

init_from_path(path: str | None = None) → PathBuf#

Initializes a GPathBuf instance with the given path.

Added in version 2.76.

Parameters:: path – a file system path

pop() → bool#

Removes the last element of the path buffer.

If there is only one element in the path buffer (for example, / on Unix-like operating systems or the drive on Windows systems), it will not be removed and False will be returned instead.

GPathBuf buf, cmp;

g_path_buf_init_from_path (&buf, "/bin/sh");

g_path_buf_pop (&buf);
g_path_buf_init_from_path (&cmp, "/bin");
g_assert_true (g_path_buf_equal (&buf, &cmp));
g_path_buf_clear (&cmp);

g_path_buf_pop (&buf);
g_path_buf_init_from_path (&cmp, "/");
g_assert_true (g_path_buf_equal (&buf, &cmp));
g_path_buf_clear (&cmp);

g_path_buf_clear (&buf);

Added in version 2.76.

push(path: str) → PathBuf#

Extends the given path buffer with path.

If path is absolute, it replaces the current path.

If path contains a directory separator, the buffer is extended by as many elements the path provides.

On Windows, both forward slashes and backslashes are treated as directory separators. On other platforms, DIR_SEPARATOR_S is the only directory separator.

GPathBuf buf, cmp;

g_path_buf_init_from_path (&buf, "/tmp");
g_path_buf_push (&buf, ".X11-unix/X0");
g_path_buf_init_from_path (&cmp, "/tmp/.X11-unix/X0");
g_assert_true (g_path_buf_equal (&buf, &cmp));
g_path_buf_clear (&cmp);

g_path_buf_push (&buf, "/etc/locale.conf");
g_path_buf_init_from_path (&cmp, "/etc/locale.conf");
g_assert_true (g_path_buf_equal (&buf, &cmp));
g_path_buf_clear (&cmp);

g_path_buf_clear (&buf);

Added in version 2.76.

Parameters:: path – a path

set_extension(extension: str | None = None) → bool#

Adds an extension to the file name in the path buffer.

If extension is NULL, the extension will be unset.

If the path buffer does not have a file name set, this function returns FALSE and leaves the path buffer unmodified.

Added in version 2.76.

Parameters:: extension – the file extension

set_filename(file_name: str) → bool#

Sets the file name of the path.

If the path buffer is empty, the filename is left unset and this function returns FALSE.

If the path buffer only contains the root element (on Unix-like operating systems) or the drive (on Windows), this is the equivalent of pushing the new file_name.

If the path buffer contains a path, this is the equivalent of popping the path buffer and pushing file_name, creating a sibling of the original path.

GPathBuf buf, cmp;

g_path_buf_init_from_path (&buf, "/");

g_path_buf_set_filename (&buf, "bar");
g_path_buf_init_from_path (&cmp, "/bar");
g_assert_true (g_path_buf_equal (&buf, &cmp));
g_path_buf_clear (&cmp);

g_path_buf_set_filename (&buf, "baz.txt");
g_path_buf_init_from_path (&cmp, "/baz.txt");
g_assert_true (g_path_buf_equal (&buf, &cmp);
g_path_buf_clear (&cmp);

g_path_buf_clear (&buf);

Added in version 2.76.

Parameters:: file_name – the file name in the path

to_path() → str | None#

Retrieves the built path from the path buffer.

On Windows, the result contains backslashes as directory separators, even if forward slashes were used in input.

If the path buffer is empty, this function returns NULL.

Added in version 2.76.
