## User overridable command paths. ##
## ------------------------------- ##
# After configure completes, it has a better idea of some of the
# shell tools we need than the defaults used by the functions shared
# with bootstrap, so set those here where they can still be over-
# ridden by the user, but otherwise take precedence.

## Source external libraries. ##

# though, so actually running these functions will sometimes place
# results into a variable named after the function, and often use
# temporary variables in the '^_G_' namespace. If you are careful to
# avoid using those namespaces casually in your sourcing script, things
# should continue to work as you expect. And, of course, you can freely
# overwrite any of the functions or variables defined here before
# calling anything to customize them.

# func_quote_arg MODEs ARG
# ------------------------
# Quote one ARG to be evaled later. MODEs argument may contain zero or more
# specifiers listed below separated by ',' character. This function returns two
# values:
# i) func_quote_arg_result
# double-quoted (when needed), suitable for a subsequent eval
# ii) func_quote_arg_unquoted_result
# has all characters that are still active within double
# quotes backslashified. Available only if 'unquoted' is specified.
#
# Available modes:
# ----------------
# 'eval' (default)
# - escape shell special characters
# 'expand'
# - the same as 'eval'; but do not quote variable references
# 'pretty'
# - request aesthetic output, i.e. '"a b"' instead of 'a\ b'. This might
# be used later in func_quote to get output like: 'echo "a b"' instead
# of 'echo a\ b'. This is slower than default on some shells.
# 'unquoted'
# - produce also $func_quote_arg_unquoted_result which does not contain
# wrapping double-quotes.
#
# Examples for 'func_quote_arg pretty,unquoted string':
#
# string | *_result | *_unquoted_result
# ------------+-----------------------+-------------------
# " | \" | \"
# a b | "a b" | a b
# "a b" | "\"a b\"" | \"a b\"
# * | "*" | *
# z="${x-$y}" | "z=\"\${x-\$y}\"" | z=\"\${x-\$y}\"

## ------ ##
## Usage. ##
## ------ ##
# This file is a library for parsing options in your shell scripts along
# with assorted other useful supporting features that you can make use
# of too.
#
# For the simplest scripts you might need only:
#
# #!/bin/sh
# . relative/path/to/funclib.sh
# . relative/path/to/options-parser
# scriptversion=1.0
# func_options ${1+"$@"}
# eval set dummy "$func_options_result"; shift
# ...rest of your script...
#
# In order for the '--version' option to work, you will need to have a
# suitably formatted comment like the one at the top of this file
# starting with '# Written by ' and ending with '# Copyright'.
#
# For '-h' and '--help' to work, you will also need a one line
# description of your script's purpose in a comment directly above the
# '# Written by ' line, like the one at the top of this file.
#
# The default options also support '--debug', which will turn on shell
# execution tracing (see the comment above debug_cmd below for another
# use), and '--verbose' and the func_verbose function to allow your script
# to display verbose messages only when your user has specified
# '--verbose'.
#
# After sourcing this file, you can plug in processing for additional
# options by amending the variables from the 'Configuration' section
# below, and following the instructions in the 'Option parsing'
# section further down.
## -------------- ##
## Configuration. ##
## -------------- ##
# You should override these variables in your script after sourcing this
# file so that they reflect the customisations you have added to the
# option parser.
# The usage line for option parsing errors and the start of '-h' and
# '--help' output messages. You can embed shell variables for delayed
# expansion at the time the message is displayed, but you will need to
# quote other shell meta-characters carefully to prevent them being
# expanded when the contents are evaled.
usage='$progpath [OPTION]...'
# Short help message in response to '-h' and '--help'. Add to this or
# override it after sourcing this library to reflect the full set of
# options your script accepts.
usage_message="\
--debug enable verbose shell tracing
-W, --warnings=CATEGORY
report the warnings falling in CATEGORY [all]
-v, --verbose verbosely report processing
--version print version information and exit
-h, --help print short or long help message and exit
"
# Additional text appended to 'usage_message' in response to '--help'.
long_help_message="
Warning categories include:
'all' show all warnings
'none' turn off all the warnings
'error' warnings are treated as fatal errors"
