* options: get rid of ambiguous option parsingwm42012-08-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Options parsing used to be ambiguous, as in the splitting into option and values pairs was ambiguous. Example: -option -something It wasn't clear whether -option actually takes an argument or not. The string "-something" could either be a separate option, or an argument to "-option". The code had to call the option specific parser function to resolve this. This made everything complicated and didn't even have a real use. There was only one case where this was actually used: string lists (m_option_type_string_list) and options based on it. That is because this option type actually turns a single option into a proxy for several real arguments, e.g. "vf*" can handle "-vf-add" and "-vf-clr". Options suffixed with "-clr" are the only options of this group which take no arguments. This is ambiguous only with the "old syntax" (as shown above). The "new" option syntax always puts option name and value into same argument. (E.g. "--option=--something" or "--option" "--something".) Simplify the code by making it statically known whether an option takes a parameter or not with the flag M_OPT_TYPE_OLD_SYNTAX_NO_PARAM. If it's set, the option parser assumes the option takes no argument. The only real ambiguity left, string list options that end on "-clr", are special cased in the parser. Remove some duplication of the logic in the command line parser by moving all argument splitting logic into split_opt(). (It's arguable whether that can be considered code duplication, but now the code is a bit simpler anyway. This might be subjective.) Remove the "ambiguous" parameter from all option parsing related code. Make m_config unaware of the pre-parsing concept. Make most CONF_NOCFG options also CONF_GLOBAL (except those explicitly usable as per-file options.)
* options: revert passing around talloc contextswm42012-08-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 48f0692ab9 "options: make option struct the talloc parent of options". This made things actually more complicated. It introduced a new parameter to the option parse and copy functions, which was used inconsistently. Some code passed a parent, some not. Morever, you have to call m_option_free() anyway, because not all options actually respect the talloc parent. There is also the question whether passing NULL as parent is supposed to work, or if you still have to implement m_config_free(). On the other hand, this simplifies nothing. I assume the intention was being able to free all option values with a single talloc_free() call, but the same goal can be reached by simply freeing the m_config struct. (The m_config talloc destructor will free each option values.) Get rid of the talloc parent context parameter. This essentially reverts commit 48f0692ab9 ("options: make option struct the talloc parent of options"). In video_out.c, make the VO priv struct the talloc parent for the m_config object, so that destroying the VO will free the options. The ability to free the m_config struct and all its managed options was introduced in commit 89a17bcda6c.
* Remove dead codewm42012-08-011-36/+0
| | | | | | | | | | | | | This was done with the help of callcatcher [1]. Only functions which are statically known to be unused are removed. Some unused functions are not removed yet, because they might be needed in the near future (such as open_output_stream for the encode branch). There is one user visible change: the --subcc option did nothing, and is removed with this commit. [1] http://www.skynet.ie/~caolan/Packages/callcatcher.html
* bstr: rename bstr() function to bstr0(), and typedef bstr to struct bstrwm42012-07-281-1/+1
| | | | | Replace all uses of bstr() with bstr0(). Also remove the ridiculous C++ workaround.
* options: make option struct the talloc parent of optionsUoti Urpala2012-07-161-1/+1
| | | | | | | | | | | Allocate dynamically-allocated option values as talloc children of the option struct. This will allow implementing per-object (VO etc) options so that simply freeing the object will free associated options too. This doesn't change quite every allocation in m_option.c, but the exceptions are legacy types which will not matter for new per-object options.
* options: simplify option parsing/setting machineryUoti Urpala2012-05-081-7/+0
| | | | | | | | | | | | Each option type had three separate operations to copy option values between memory locations: copy between general memory locations ("copy"), copy from general memory to active configuration of the program ("set"), and in the other direction ("save"). No normal option depends on this distinction any more. Change everything to define and use a single "copy" operation only. Change the special options "include" and "profile", which depended on hacky option types, to be special-cased directly in option parsing instead. Remove the now unused option types m_option_type_func and m_option_type_func_param.
* options: change option parsing to use bstrUoti Urpala2011-07-291-5/+6
| | | | | | Using bstr allows simpler parsing code, especially because it avoids the need to modify or copy strings just to terminate extracted substrings.
* options: indicate ambiguous option parameters explicitlyUoti Urpala2011-07-291-1/+1
| | | | | | | | 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.
