## ------ ## ## 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.
# 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.

MODE must be one of the following:
clean remove files from the build directory
compile compile a source file into a libtool object
execute automatically set library path, then run a program
finish complete the installation of libtool libraries
install install libraries or executables
link create a library or an executable
uninstall remove libraries from an installed directory
MODE-ARGS vary depending on the MODE. When passed as first option, '--mode=MODE' may be abbreviated as 'MODE' or a unique abbreviation of that.

RM is the name of the program to use to delete files associated with each FILE

with it are deleted. Otherwise, only FILE itself is deleted using RM."

Compile a source file into a libtool library object.
This mode accepts the following additional options:
-o OUTPUT-FILE set the output file name to OUTPUT-FILE
-no-suppress do not suppress compiler output for multiple passes
-prefer-pic try to build PIC objects only
-prefer-non-pic try to build non-PIC objects only
-shared do not build a '.o' file suitable for static linking

-Wc,FLAG

COMPILE-COMMAND is a command to be used in creating a 'standard' object file
from the given SOURCEFILE.
The output file name is determined by removing the directory component from
SOURCEFILE, then substituting the C source code suffix '.c' with the
library object suffix, '.lo'."
;;
Automatically set library path, then run a program.
This mode accepts the following additional options:
-dlopen FILE add the directory containing FILE to the library path
This mode sets the library path environment variable according to '-dlopen'
flags.
If any of the ARGS are libtool executable wrappers, then they are translated
into their corresponding uninstalled binary, and any of their required library
directories are added to the library path.
Then, COMMAND is executed, with ARGS as arguments."
;;
Link object files or libraries together to form another library, or to
create an executable program.
LINK-COMMAND is a command using the C compiler that you would use to create
a program from several object files.
The following components of LINK-COMMAND are treated specially:
-all-static do not do any dynamic linking at all
-avoid-version do not add a version suffix if possible
-bindir BINDIR specify path to binaries directory (for systems where
libraries must be found in the PATH setting at runtime)
-dlopen FILE '-dlpreopen' FILE if it cannot be dlopened at runtime
-dlpreopen FILE link in FILE and add its symbols to lt_preloaded_symbols
-export-dynamic allow symbols from OUTPUT-FILE to be resolved with dlsym(3)
-export-symbols SYMFILE
try to export only the symbols listed in SYMFILE
-export-symbols-regex REGEX
try to export only the symbols matching REGEX
-LLIBDIR search LIBDIR for required installed libraries
-lNAME OUTPUT-FILE requires the installed library libNAME
-module build a library that can dlopened
-no-fast-install disable the fast-install mode
-no-install link a not-installable executable
-no-undefined declare that a library does not refer to external symbols
-o OUTPUT-FILE create OUTPUT-FILE from the specified objects
-objectlist FILE use a list of object files found in FILE to specify objects
-os2dllname NAME force a short DLL name on OS/2 (no effect on other OSes)
-precious-files-regex REGEX
don't remove output files matching REGEX
-release RELEASE specify package release information
-rpath LIBDIR the created library will eventually be installed in LIBDIR
-R[ ]LIBDIR add LIBDIR to the runtime path of programs and libraries
-shared only do dynamic linking of libtool libraries
-shrext SUFFIX override the standard shared library file extension
-static do not do any dynamic linking of uninstalled libtool libraries
-static-libtool-libs do not do any dynamic linking of libtool libraries
-version-info CURRENT[:REVISION[:AGE]]
specify library version info [each variable defaults to 0]
-weak LIBNAME declare that the target provides the LIBNAME interface
-Wc,FLAG
-Xcompiler FLAG pass linker-specific FLAG directly to the compiler
-Wa,FLAG
-Xassembler FLAG pass linker-specific FLAG directly to the assembler
-Wl,FLAG
-Xlinker FLAG pass linker-specific FLAG directly to the linker
-XCClinker FLAG pass link-specific FLAG to the compiler driver (CC)
All other options (arguments beginning with '-') are ignored.
Every other argument is treated as a filename. Files ending in '.la' are
treated as uninstalled libtool libraries, other files are standard or library
object files.
If the OUTPUT-FILE ends in '.la', then a libtool library is created,
only library objects ('.lo' files) may be specified, and '-rpath' is
required, except when creating a convenience library.
If OUTPUT-FILE ends in '.a' or '.lib', then a standard library is created
using 'ar' and 'ranlib', or on Windows using 'lib'.
If OUTPUT-FILE ends in '.lo' or '.$objext', then a reloadable object file
is created, otherwise an executable program is created."

Instead it simply concatenates the arguments, separated by ' ', and calls
CreateProcess(). We must quote the arguments since Win32 CreateProcess()
interprets characters like ' ', '\t', '\\', '"' (but not '<' and '>') in a
special way:
- Space and tab are interpreted as delimiters. They are not treated as
delimiters if they are surrounded by double quotes: "...".
- Unescaped double quotes are removed from the input. Their only effect is
that within double quotes, space and tab are treated like normal
characters.
- Backslashes not followed by double quotes are not special.
- But 2*n+1 backslashes followed by a double quote become
n backslashes followed by a double quote (n >= 0):
\" -> "
\\\" -> \"
\\\\\" -> \\"

# The TAGs below are defined such that we never get into a situation # where we disable both kinds of libraries. Given conflicting # choices, we go for a static library, that is the most portable, # since we can't tell whether shared libraries were disabled because # the user asked for that or because the platform doesn't support # them. This is particularly important on AIX, because we don't # support having both static and shared libraries enabled at the same # time on that platform, so we default to a shared-only configuration. # If a disable-shared tag is given, we'll fallback to a static-only # configuration. But we'll never go from static-only to shared-only.
