When parsing the command line, map "--no-foo" to "--foo=no" if an
option named "foo" exists and is a flag option. Non-empty parameters
are not allowed with this syntax ("--no-foo=no" is invalid).
This implementation is different from the existing "--nofoo" variants
for most flag options. Those are implemented as completely separate
options; there's an option named "fs" and a separate option named
"nofs" (thus "--no-nofs" actually works after this change...). The
reason for adding the new syntax is to support the much more standard
"--no-" prefix and to allow eventually cleaning up the option handling
(though the "nofoo" variants of existing options can't be removed soon
due to backwards compatibility).
The command line parsing code recorded the next commandline argument,
if any, as the parameter of any option recorded to playtree. Thus a
command line like "mplayer file -fs -aid 1" would record option "-fs"
with a bogus argument "-aid". Historically this triggered no visible
problems because such bogus arguments were silently ignored when
interpreting the options later. However after recent commit 507fa7e2c2
("options: indicate ambiguous option parameters explicitly")
parameters to flag options are no longer ignored, and the bogus values
now triggered parsing errors. Add a check to stop recording parameters
for old-style single-dash options if m_config_check_option() says the
option did not consume any arguments.
If parsing an option fails, print a string corresponding to the parse
function return value (M_OPT_MISSING_PARAM etc). The primary
motivation is that the parsing code already outputs messages
explaining most problems, but does not itself print anything in the
missing parameter case. Before double-dash --options such errors were
rare (or rather they resulted in the next commandline argument being
silently misinterpreted as an argument to the previous option
instead); but now an argument like "--ss" should give a better
indication about the problem than just "Error parsing option".
Allow writing commandline options with two leading dashes. In this
mode a parameter for the option, if any, follows after a '=';
following separate commandline arguments are never consumed as a
parameter to a previous double-dash option.
Flag options may omit parameter and behave like old single-dash
syntax. "--fs=yes", "--fs=no" and "--fs" are all valid; the first two
behave like configuration file "fs=yes" and "fs=no", and last is the
same as old "-fs" (same effect as "--fs=yes").
A "--" argument on the command line is used to indicate that all
following arguments should be interpreted as filenames, not options.
Specifying it as the last argument was considered an error. I see no
particular reason to forbid the following filename list to be empty,
nor do other programs with similar functionalitly I know about treat
it that way. So just ignore a "--" with no more arguments.
Command line options like "-foo xyz" are ambiguous: "xyz" may be a
parameter to the option "foo" or an unrelated argument. Instead of
relying on the struct m_config mode field (commandline/file) pass
parameters to specify ambiguous mode explicitly. Meant for "--foo"
options which are never ambiguous on command line either.
The global was used in the function cfg_include which handles the
-include option. Make the address available in that function by
creating a new dynamically allocated option in m_config_new that has
the address in the option's private data.
asxparser.c also used the global. Making it available through all ways
the code could get called required a number of relatively straightforward
changes to playtree and menu code.
Include the corresponding .h file in command.c, parser-cfg.c and
parser-mpcmd.c. This allows the compiler to check that the
declarations in the .h file match the actual defition.
