"LaTeXML::Util::Pathname" - portable pathname and file-system utilities
This module combines the functionality File::Spec and File::Basename to give a consistent set of filename utilities for LaTeXML. A pathname is represented by a simple string. Pathname Manipulations "$path = pathname_make(%peices);" Constructs a pathname from the keywords in pieces dir : directory name : the filename (possibly with extension) type : the filename extension "($dir,$name,$type) = pathname_split($path);" Splits the pathname $path into the components: directory, name and type. "$path = pathname_canonical($path);" Canonicallizes the pathname $path by simplifying repeated slashes, dots representing the current or parent directory, etc. "$dir = pathname_directory($path);" Returns the directory component of the pathname $path. "$name = pathname_name($path);" Returns the name component of the pathname $path. "$type = pathname_type($path);" Returns the type component of the pathname $path. "$path = pathname_concat($dir,$file);" Returns the pathname resulting from concatenating the directory $dir and filename $file. "$boole = pathname_is_absolute($path);" Returns whether the pathname $path appears to be an absolute pathname. "$boole = pathname_is_url($path);" Returns whether the pathname $path appears to be a url, rather than local file. "$rel = pathname_is_contained($path,$base);" Checks whether $path is underneath the directory $base; if so it returns the pathname $path relative to $base; otherwise returns undef. "$path = pathname_relative($path,$base);" If $path is an absolute, non-URL pathname, returns the pathname relative to the directory $base, otherwise simply returns the canonical form of $path. "$path = pathname_absolute($path,$base);" Returns the absolute pathname resulting from interpretting $path relative to the directory $base. If $path is already absolute, it is returned unchanged. File System Operations "$modtime = pathname_timestamp($path);" Returns the modification time of the file named by $path, or undef if the file does not exist. "$path = pathname_cwd();" Returns the current working directory. "$dir = pathname_mkdir($dir);" Creates the directory $dir and all missing ancestors. It returns $dir if successful, else undef. "$dest = pathname_copy($source,$dest);" Copies the file $source to $dest if needed; ie. if $dest is missing or older than $source. It preserves the timestamp of $source. "$path = pathname_find($name,%options);" Finds the first file named $name that exists and that matches the specification in the keywords %options. An absolute pathname is returned. If $name is not already an absolute pathname, then the option "paths" determines directories to recursively search. It should be a list of pathnames, any relative paths are interpreted relative to the current directory. If "paths" is omitted, then the current directory is searched. If the option "installation_subdir" is given, it indicates, in addition to the above, a directory relative to the LaTeXML installation directory to search. This allows files included with the distribution to be found. The "types" option specifies a list of filetypes to search for. If not supplied, then the filename must match exactly. The type "*" matches any extension. "@paths = pathname_findall($name,%options);" Like "pathname_find", but returns all matching (absolute) paths that exist.
