NAME
"LaTeXML::Util::Pathname" - portable pathname and file-system utilities
DESCRIPTION
This module combines the functionality File::Spec and File::Basename to give a consistent set of filename utilties 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 $path appears to be an absolute pathname.
"$path = pathname_relative($path,$base);"
Returns the path to file $path relative to the directory $base.
"$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 $name is not already an absolute pathname, then the option "paths" determines directories to recursively search. It should be a
list of pathnames, any relative paths are interpreted relative to the current directory. If "paths" is omitted, then the current
directory is searched.
If the option "installation_subdir" is given, it indicates, in addition to the above, a directory relative to the LaTeXML installation
directory to search. This allows files included with the distribution to be found.
The "types" option specifies a list of filetypes to search for. If not supplied, then the filename must match exactly.
"@paths = pathname_findall($name,%options);"
Like "pathname_find", but returns all matching paths that exist.
