Lix command-line arguments
==========================

Synopsis
--------

Any of these starts Lix in interactive mode:

    lix                                     Main menu
    lix level.txt                           Start the given level
    lix replay.txt                          Run replay on its included level
    lix level.txt replay.txt                Run replay on the given level
    lix --pointed-to replay.txt             Run replay on its pointed-to level

Extra switches for interactive mode:

    -w                      run windowed at 640x480
    --resol=800x600         run windowed at given resolution
    --fullscreen            use software fullscreen (good Alt+Tab)
    --hardfull=1600x900     use hardware fullscreen at given resolution

These start Lix as a pure command-line tool, they don't create a window:

    lix --verify replay1 [replay2 ...]      Verify single replays or dirs
    lix --coverage replay1 [replay2 ...]    Verify, then print coverage stats
    lix --image level1 [level2 ...]         Export levels as PNG pictures

Extra switches:

    -h or -? or --help      print help and exit
    -v or --version         print version and exit

lix
---

No arguments given: Start the game in interactive mode, go to the main menu.
You can add switches like -w or --resol=800x600 to force a windowed resolution.

lix level.txt
-------------

Start in interactive mode, bypass the main menu and singleplayer browser,
and immediately play the given level.

lix replay.txt
--------------

Start in interactive mode, bypass the main menu and replay browser,
and immediately run the given replay.

The replay runs against the included level. If there is no level included
in the replay file, the replay runs against the pointed-to level. If the
pointed-to level is missing or bad, abort with an error before even opening
the graphical window for interactive mode.

lix --pointed-to replay.txt
---------------------------

Start in interactive mode, bypass the main menu and replay browser,
and immediately run the given replay against its pointed-to level.

When the pointed-to level is missing or bad, abort with an error before even
opening the graphical window for interactive mode. Under no circumstances,
the replay runs against the level included in the replay file.

After running the replay, you will go to the replay browser.

lix level.txt replay.txt
------------------------

Start in interactive mode, bypass the main menu and browsers, and immediately
run the given replay against the given level.

I don't know where you should end up afterwards.

lix --verify replay1 [replay2 ...]
----------------------------------

Every argument (replay1, replay2, ...) may be a single replay file, or a
directory. Passing a directory behaves as if you had passed all replay files
that you could find recursively within the passed directory.

For each replay, this prints to standard console output whether the replay
solves the pointed-to level.

This never examines included levels. If there is only an included level and
no pointed-to level, the replay produces a level-missing line in the output.

lix --coverage replay1 [replay2 ...]
------------------------------------

Like --verify, but afterwards, this prints a list of levels that lack a proof
of solvability. A level is printed as not-yet-covered iff all of these apply:

*   None of the verified replays solvels that level.
*   You have verified a replay that points to a level from the same
    level directory, no matter whether that replay solved or failed.

Example usage: You maintain replays for your awesome level pack in
./replays/mypack/rank1, ./replays/mypack/rank2, and so on. Each of these
directories has many replays for the particular rank. Two useful command lines:

lix --coverage replays/mypack

    This verifies all replays, because you could find them recursively within
    the directory replays/mypack. Then, this prints the levels from your pack
    that you haven't covered with any replay. It won't list levels from other
    people's level packs.

lix --coverage replays/mypack/rank1

    This verifies all replays for rank 1, and lists all rank-1 levels that
    you haven't covered with any replay. It won't list uncovered rank-2 levels
    because you didn't verify any level from the rank-2 level directory.
