# Macros to assist in the handling of paths with spaces

#	encodepath - Uses spacealt, uses /, space-sep-list

#		     Used to conatins lists of paths that may contain

#		     spaces. Used for INCLUDE and LIB paths

#

#	decodepath - Decodes an encoded path-list.

#		     User specifies the item prefix and suffix.

#		     Return list uses \ and may have spaces in pathnames

#	             Prefix items with 1st-arg

#                    Join items with 2nd arg

#

# Usage:

#	aa = $(call encodepath,c:\Program Files)

#	$(call decodepath,-I,;,$(aa))

#  Macros to convert relative to absolute paths

#

#   Work around for a bug in make 3.81 where abspath assumes that the input

#   is a relative path. The work around checks for paths that have a : or start

#   with a '/ - and assumes these are absolute.

#   It will only call makes 'abspath' for relative paths.

#..	Invoke RunTime support operations

#

#	Usage:

#		$(JatsRunTime) function_name -- args

#       Notes:

#		Don't use " to quote arguments as it will invoke a shell

#		under windows (and others). This can only slow it down.

#		Using ' is OK

#

#   Usage:      $(call CopyFile,Text,dest,file,fmode)

#               $(call UncopyFile,Text,file)

#

#   Notes:

#       dest, file and path

#	May have spaces in them

#		These will have been escaped with a '\' which will

#		need to be removed. The '\ ' is required to keep make

#		happy elsewhere.

#

#	Current implementation uses a dedicated JATS-internal program to perform

#	the operations. This is much better than the previous implementation

#	which was shell-based. Its problems included:

#		1) Very slow under Windows

#		2) Special handling on $

#		3) Windows Path length limitation of < ~260 characters

#

#	Implementation note:

#		1) Do not get the shell involved in invoking the command

#	           Quote args in '' not "" as "" will trigger shell usage

#		   This is good as we don't need/want shell expansion either

#		   Shell startup is slow under windows.

#		2) Paths use '/'. This is passed though to the utility

#

#	Macros

#	NiceName - convert a '\ ' pathname into an string with plain spaces

#		   Convert nasty characters into %nn to get past the shell

#		   Characters to convert are:

#		   	Percent(%)		- Its our escape lead-in

#						  Not sure make handles such file

#		   	singlequote(')		- It quotes our arguments

#		   	Ampersand(&)		- If found make uses shell

#
