Option to produce splitted arguments array (as in pre-0.9.5)

[Artalus]

I used compiledb for a while to analyze Makefiles produced by our legacy build system. It was very convenient since compile_commands.json file contained separate field arguments: [] which I could then grep using jq. After recent update 0.9.2 -> 0.9.7 my scripts broke down since now compiledb just copies whole long compile command into a single command field. It would be nice to have an option to add arguments array to the output.

Hi @Artalus , Thanks for reporting this. Could you please test locally with the latest master.

Also, note that several improvements/features/changes have been implemented since version 0.9.2, for example:

• By default, it runs in incremental mode (i.e: Updates the current compile_commands.json if it exists (unless -f is used) instead of rewriting it entirely always, this is particularly useful when running non clean builds with changes in flags/source files, so the compiledb is almost(?) ready to be used as a real make wrapper.
• Much better parsing logic (using a bash lexer internally to extract build commands even from quite complex bash expressions, e.g: conditionals, substitution cmds, etc)
• Better handling of compiler wrappers (removing them from final build commands)
• Finally working well with autotools-based build systems (tested with bitcoin core build system, for example)
• By default, it runs in what we called a strict mode, which ignore source files which do not exist in the file system (If desired one can disable those checkings using -S option, useful for example when processing build logs where the actual code base is not on the host's file system.

Thank you, it works fine now. Only I thought the joined command string was considered a feature, not a regression that should be removed completely, but this one is up to you and clang-tools compliance :)
