CHANGE LOG
#############################################################################
VERSION 1.12
x Added a copyright statement at the request of a Debian administrator.
https://rt.cpan.org/Public/Bug/Display.html?id=62017
VERSION 1.11
x Added prefixadmin to the MANIFEST
VERSION 1.1
x Supports the "secure" option attribute. (Also, all options which end in "pass" or "password"
are assumed to be secure.) The value is a security level: 1=[don't print the value in a help screen].
2=[ensure that the value can never be supplied on a command line or from the environment but
only from a file that only the user running the program has read/write access to]
VERSION 1.07
x Automagically add $PREFIX/lib/perl5 to @INC (only if it exists), else $PREFIX/lib/perl
Also check $PREFIX/share/perl and add it to @INC if it exists.
Surprisingly, $PREFIX/share/perl and $PREFIX/lib/perl seem to be the directories created
and used under Ubuntu 8.04's perl.
x Allow dashes ("-") as a variable name (i.e. foo-bar = 1).
In doing this, I actually allow that any characters other than spaces/tabs/= can make up the variable name
x Trim leading and trailing tabs (as well as spaces) from the line
VERSION 1.06
x Remove trailing \r from option files (for Windows-edited .conf files)
VERSION 1.05
x Substitutions of ${prefix} in option files now works even if only defined by assumption
This is particularly valuable for portability between environments of CGI scripts and cron scripts.
VERSION 1.04
x Fixed RT Bug #33597: Problem of ignoring drive letter on Win32 filesystem.
VERSION 1.03
x better use of /\s*/ instead of / */ so that tabs don't catch you off-guard
x enable application use of App::Options objects to read additional data structures
VERSION 1.02
x ENV{FOO} = x in app.conf sets environment variable "FOO" (i.e. LD_LIBRARY_PATH)
x added perl_restart option to re-exec() the program so that it picks up a new LD_LIBRARY_PATH
x save original @ARGV to @App::Options::ARGV (used for perl_restart/re-exec())
x line continuation characters strip off newlines and leading spaces
VERSION 1.01
x removed dependency in Makefile.PL on Config.pm (which was causing a false error on "make test")
VERSION 1.00
x clean up for v1.00. no dependency on Module::Build (which has been giving problems)
x add default values for MANPATH, LD_LIBRARY_PATH to bin/prefix
x added t/file.txt so the test process doesn't spew warnings
VERSION 0.99
x fixed a condition that didn't work on Windows when executing in current dir
x fix double slash /usr/rubicon/test/bin//app.conf
x improved --debug_options, --debug_options=[1-7] output
VERSION 0.98
x disabled some tests that cause failure on MSWin32
VERSION 0.97
x enable "here documents", var = <<EOF
x enable file/cmd variables, var = < filename (or "cmd|")
x allow line continuation chars, i.e. var = hello \\nworld
VERSION 0.96
x cleaned up some of the --debug_options output
x tests run clean on Win32
x used File::Spec to make file/directory manipulation platform-independent (i.e. Win32)
NOTE: I used a mix of platform-independent File::Spec functions and explicit
conversion from "\" paths to POSIX-compliant "/" paths. This is because the
purist form of leaving "\" paths for Win32 was causing weirdness. When
I would interpolated the string or use it in a regular expression, the
backslashes were interacting badly. The only reason I'm not going to 1.0
with this is that I want to see it pass Win32 tests on the CPAN testers
farm before giving it that number.
VERSION 0.95
x made a change (hack) to Build.PL to get it to work with the CPAN shell
VERSION 0.94
x use Module::Build instead of ExtUtils::MakeMaker
x add a META.yaml file to the distribution (from "Build distmeta")
x add --version support (print out versions of all modules)
x make prefix authoritative before defaults so that we can use ${prefix} in substitutions
x set defaults in order of "options" to ensure the correct order for variable substitution
VERSION 0.93
x prefix can now be set in $prog_dir/app.conf to find $prefix/etc/app/app.conf
x single-line sections in option files are no longer independent of the
section they are in. Both the section-condition and the line-condition
must now be satisfied for a value to be set.
VERSION 0.92
x cleaned up some warnings which appeared under -w (concatenation of undef)
x add system-supplied hostname and host options
x variable substitution works with environment vars (url = http://$ENV{HOST})
x auto-import of environment vars named "APP_*" even if not otherwise defined
x usage: undefined values appear as "[undef]" rather than "[]"
x usage: options appear as "--var=<value>" rather than "--var=<var>"
x usage: "args_description" describes what's left on cmd line after options removed
x usage: "value_description" describes option value (instead of "<value>")
x added an examples directory
x added a benchmark directory
x default is $Config{prefix} instead of /usr/local
x improve debug_options (env vars, etc.) (implemented 6 levels of debug_options)
VERSION 0.91
x show_all is off by default whenever "option" or "options" used
x remove app_path_info
VERSION 0.90
x new "use App::Options (...);" syntax (rather than ->init(...) syntax)
VERSION 0.64
x added $VERSION to App::Options (use VERSION_FROM in Makefile.PL)
x fixed bug where "show_all" wasn't showing all on --help
x touched up titles on pod documentation
x implement import() method to use module outside the BEGIN block (i.e. use App::Options (@args))
x update documentation with new syntax using import() method
x improve show_all logic: show_all = 1 by default always unless overridden
VERSION 0.63
x improve documentation (api reference, logic flow, usage tutorial)
x "integer" type now matches integers with underscores (i.e. 1_000_000)
x "float" type now matches numbers with underscores (i.e. 1_000.000_001)
x added /etc/app/app.conf to the end of the option file search path
x default "prefix" is now "/usr/local" instead of "."
x {env} attribute of "" means don't search any env variable
VERSION 0.62
x [prog] matches "prog" only. [/prog/] matches by regular expression.
In version 0.61, the section [list] would match ($app =~ /list/).
In version 0.62, the section [list] only matches ($app eq "list"),
while [/list/] matches ($app =~ /list/).
x type="/regexp/" matches regexp. unknown types ignored.
In version 0.61, an option type which was not one of the known
option types (integer, float, date, datetime, etc.), was considered
automatically as a regular expression.
In version 0.62, only types which take the form "/regexp/" are
actually regular expressions. All other unknown "types" are ignored.
This sets the groundwork for better forward-compatibility when new
types are introduced, they will not break older versions of the code.
It also just seems clearer.
x "show_all" option - shows all defined options, not just in [ options ]
In version 0.61, the --help option would show all variables defined
in the code, on the command line, or in any of the files (i.e.show_all=1).
However, if the "options" argument is used in the init() method in the
code, only those enumerated options would be shown (i.e. show_all=0).
In version 0.62, the same behavior applies unless the "show_all"
parameter is given explicitly.
x quoting, var = " hello world "
In version 0.61, variable values in the option file had leading and
trailing spaces removed. This meant that a value of a single space
was not possible.
In version 0.62, the same behavior applies. However, if the
remaining text starts with " and ends with ", those quote marks are
removed. i.e. var = " " will result in the value of a single space,
and message = "Hello world. " will have a trailing space.
x check list of configurable environment vars ("env") instead of
"APP_${uc_var}"
In version 0.61, variable values could be supplied by specifying the
variable prefixed with "APP_". (i.e. "path" could be specified
with "APP_PATH")
In version 0.62, a list of environment variable names may be given
and the first with a supplied value is used for the value.
(i.e. options => { path => { env => "PATH" } } will cause the
"path" variable to be set from the "PATH" environment variable.)
VERSION 0.61
x Initial release
