|$path = pathname_make(%peices);||
Constructs a pathname from the keywords in pieces
dir : directory
name : the filename (possibly with extension)
type : the filename extension
|($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.|
$modtime = pathname_timestamp($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.
