Add map directory support

[zoff99]

i have this set in the config file:

        <mapset enabled="yes">
            <map type="binfile" enabled="yes" data="/media/card/navit/maps/*.bin"/>
        </mapset>

but when there are 2 .bin files present only the first gets loaded. if i give only the directory (without *.bin) navit crashes and does not startup

It's luck that this works for one map an not intentional. Map only takes a single map file as argument and a directory is not a file.

You should configure navit as follow:

<mapset enabled="yes">
  <map type="binfile" enabled="yes" data="/media/card/navit/maps/map1.bin"/>
  <map type="binfile" enabled="yes" data="/media/card/navit/maps/map2.bin"/>
</mapset>

zoff99, feel free to reopen if you see the need.

what kind of response would you like? there is definitly a bug.

in the documentation is states clearly! ​http://wiki.navit-project.org/index.php/OpenStreetMap#Tips

    *  To avoid changing navit.xml if you update your maps and the maps have different file names use the wildcard (*.bin) in your navit.xml file. For example: 

<map type="binfile" enabled="yes" data="/media/mmc2/maps/*.bin"/>

that i would like have working. it (would be) a great feature. e.g. if you travel you can just put france.bin and germany.bin on your SD-card and after the trip just delete one of those files, and all is well. WITHOUT having to have the navit.xml all the time.

This kind of response :).

This implies you remove the other one from the containing directory if it comes first in the alphabet and implies the OS supports globing. Really hackish, therefore in the tips section.

One could either implement the "multiple maps per map tag" or a "mapdir tag" or something slightly different - an add/remove map dialog in the gui.

A map directory with automatic map type detection and all maps enabled if the "mapdir" is enabled seems what you want. The map type detection is necessary as you could be using commercial maps for Germany and add an OSM map for France.

as a first step it would be enough to just try to load all '*.bin' files in a specific directory. and if the OS does not support globing or the files are not mapfiles just ignore them. that would not break any existing stuff, but would allow for the feature i described.

maybe have a new tag like this:

<map type="binfile_dir" enabled="yes" data="/media/mmc2/maps/"/>

and then all files in /media/mmc2/maps/ would be loaded as bin-type files, and if there is any kind of error just ingore and continue ...

I agree that it could be convenient. Currently * would load xml files, each one of them describing one .bin.

This bug seems t be fixed during the years. I tried it with the mentioned config and the preshiped bin and on additional from my state. Works good-> close ticket.
