1253 # ------------------------

1255 # specifiers listed below separated by ',' character. This function returns two
1256 # values:
1257 # i) func_quote_arg_result
1258 # double-quoted (when needed), suitable for a subsequent eval
1259 # ii) func_quote_arg_unquoted_result
1260 # has all characters that are still active within double
1261 # quotes backslashified. Available only if 'unquoted' is specified.
1262 #
1263 # Available modes:
1264 # ----------------
1265 # 'eval' (default)
1266 # - escape shell special characters
1267 # 'expand'
1268 # - the same as 'eval'; but do not quote variable references
1269 # 'pretty'
1270 # - request aesthetic output, i.e. '"a b"' instead of 'a\ b'. This might
1271 # be used later in func_quote to get output like: 'echo "a b"' instead
1272 # of 'echo a\ b'. This is slower than default on some shells.
1273 # 'unquoted'
1274 # - produce also $func_quote_arg_unquoted_result which does not contain
1275 # wrapping double-quotes.
1276 #
1277 # Examples for 'func_quote_arg pretty,unquoted string':
1278 #
1279 # string | *_result | *_unquoted_result

1556 ## Usage. ##
1557 ## ------ ##
1558
1559 # This file is a library for parsing options in your shell scripts along
1560 # with assorted other useful supporting features that you can make use
1561 # of too.
1562 #
1563 # For the simplest scripts you might need only:
1564 #
1565 # #!/bin/sh
1566 # . relative/path/to/funclib.sh
1567 # . relative/path/to/options-parser
1568 # scriptversion=1.0
1569 # func_options ${1+"$@"}
1570 # eval set dummy "$func_options_result"; shift
1571 # ...rest of your script...
1572 #
1573 # In order for the '--version' option to work, you will need to have a
1574 # suitably formatted comment like the one at the top of this file
1575 # starting with '# Written by ' and ending with '# Copyright'.
1576 #
1577 # For '-h' and '--help' to work, you will also need a one line
1578 # description of your script's purpose in a comment directly above the
1579 # '# Written by ' line, like the one at the top of this file.
1580 #
1581 # The default options also support '--debug', which will turn on shell
1582 # execution tracing (see the comment above debug_cmd below for another
1583 # use), and '--verbose' and the func_verbose function to allow your script
1584 # to display verbose messages only when your user has specified
1585 # '--verbose'.
1586 #
1587 # After sourcing this file, you can plug in processing for additional
1588 # options by amending the variables from the 'Configuration' section
1589 # below, and following the instructions in the 'Option parsing'
1590 # section further down.
