If you want to operate on the files and directories which the paths represent, see [[Module (chicken file)]]. === absolute-pathname? <procedure>(absolute-pathname? PATHNAME)</procedure> Returns {{#t}} if the string {{PATHNAME}} names an absolute pathname, and returns {{#f}} otherwise. === decompose-pathname <procedure>(decompose-pathname PATHNAME)</procedure> Returns three values: the directory-, filename- and extension-components of the file named by the string {{PATHNAME}}. For any component that is not contained in {{PATHNAME}}, {{#f}} is returned. === make-pathname === make-absolute-pathname <procedure>(make-pathname DIRECTORY FILENAME [EXTENSION])</procedure><br> <procedure>(make-absolute-pathname DIRECTORY FILENAME [EXTENSION])</procedure> Returns a string that names the file with the components {{DIRECTORY, FILENAME}} and (optionally) {{EXTENSION}} with {{SEPARATOR}} being the directory separation indicator (usually {{/}} on UNIX systems and {{\}} on Windows, defaulting to whatever platform this is running on). {{DIRECTORY}} can be {{#f}} (meaning no directory component), a string or a list of strings. {{FILENAME}} and {{EXTENSION}} should be strings or {{#f}}. {{make-absolute-pathname}} returns always an absolute pathname. === pathname-directory === pathname-file === pathname-extension <procedure>(pathname-directory PATHNAME)</procedure><br> <procedure>(pathname-file PATHNAME)</procedure><br> <procedure>(pathname-extension PATHNAME)</procedure> Accessors for the components of {{PATHNAME}}. If the pathname does not contain the accessed component, then {{#f}} is returned. === pathname-replace-directory === pathname-replace-file === pathname-replace-extension <procedure>(pathname-replace-directory PATHNAME DIRECTORY)</procedure><br> <procedure>(pathname-replace-file PATHNAME FILENAME)</procedure><br> <procedure>(pathname-replace-extension PATHNAME EXTENSION)</procedure> Return a new pathname with the specified component of {{PATHNAME}} replaced by a new value. === pathname-strip-directory === pathname-strip-extension <procedure>(pathname-strip-directory PATHNAME)</procedure><br> <procedure>(pathname-strip-extension PATHNAME)</procedure> Return a new pathname with the specified component of {{PATHNAME}} stripped. === normalize-pathname <procedure>(normalize-pathname PATHNAME [PLATFORM])</procedure> Performs a simple "normalization" on the {{PATHNAME}}, suitably for {{PLATFORM}}, which should be one of the symbols {{windows}} or {{unix}} and defaults to on whatever platform is currently in use. All relative path elements and duplicate separators are processed and removed. If {{NAME}} ends with a {{/}} or is empty, the appropriate slash is appended to the tail. No directories or files are actually tested for existence; this procedure only canonicalises path syntax. === directory-null? <procedure>(directory-null? DIRECTORY)</procedure> Does the {{DIRECTORY}} consist only of path separators and the period? {{DIRECTORY}} may be a string or a list of strings. === decompose-directory <procedure>(decompose-directory DIRECTORY)</procedure> Returns 3 values: the {{base-origin}}, {{base-directory}}, and the {{directory-elements}} for the {{DIRECTORY}}. ; {{base-origin}} : a {{string}} or {{#f}}. The drive, if any. ; {{base-directory}} : a {{string}} or {{#f}}. A directory-separator when {{DIRECTORY}} is an {{absolute-pathname}}. ; {{directory-elements}} : a {{list-of string}} or {{#f}}. The non-directory-separator bits. {{DIRECTORY}} is a {{string}}. * On Windows {{(decompose-directory "c:foo/bar")}} => {{"c:" #f ("foo" "bar")}} === Windows specific notes Use of UTF8 encoded strings for pathnames is not supported. Windows uses a 16-bit UNICODE encoding with special system calls for wide-character support. Only single-byte string encoding can be used. --- Previous: [[Module (chicken module)]] Next: [[Module (chicken platform)]] Description of your changes:
