[mkgmap-dev] Please check if help is okay

Hi all,

okay, I've now also added options --mdr7-del, --mdr7-excl, and --poi-excl-index.
Option --split-name-index is no longer temporay.
The corresponding part of the help now looks like this:

--split-name-index
        An option to enable indexing each part of a street name separately.
        So for example if the street is "Aleksandra Gryglewskiego" then you will be able to
        search for it as both "Aleksandra" and "Gryglewskiego".  It will also increase the
        size of the index.  Useful in countries where searching for the first word in name
        is not the right thing to do. Words following an opening bracket '(' are ignored.
        See also option road-name-config.

--road-name-config=file
        This option handles the problem that some countries have road names which
        ofter start or end with very similar words, e.g. in France the first word
        is very often 'Rue', ofter followed by a preposition like 'de la' or 'des'.
        This leads to rather long road names like 'Rue de la Concorde' where only
        the word 'Concorde' is really interesting. In the USA, you ofter have names
        like 'West Main Street' where only the word 'Main' is important.
        Garmin software has some tricks to handle this problem. It allows to use
        special characters in the road labels which mark the beginning and end of
        the important part. In combinarion with option split-name-index
        only the words in the important part are indexed.

        There are two different visiual effects of this option:
        - On the PC, when zooming out, the name 'Rue de la Concorde' is only
                rendered as 'Concorde'.
        - The index for road names only contains the important part of the name.
                You can search for road name Conc to find road names like 'Rue de la Concorde'.
                One problem: Search for 'Rue' will not list 'Rue de la Concorde'
                or 'Rue du Moulin'. It may list 'Rueben Brookins Road' if that is in the map.
                Only MapSource shows a corresponding hint.

        Another effect is that the index is smaller.
        The option specifies the path to a file which gives the details. See
        comments in the sample roadNameConfig.txt for further details.

--mdr7-excl
        This option allows to specify words which should not be in the road index.
        It was added before option road-name-config and is probably no longer needed.
        Example usage: --x-mdr7-excl="Road, Street, Straße, Weg"

--mdr7-del
        Use this option if your style adds strings to the labels of roads which you
        want to see in the map but which should not appear in the result list
        of a road name / address search. The list is used like this:
        For each road label mkgmap searches the last blank. If one is found, it checks
        if the word after it appears in the given list. If so, the word is removed
        and the search is repeated. The remaining string is used to create the index.

--poi-excl-index
        By default, mkgmap indexes the following POI types with a non-empty label:
        - 0x00 .. 0x0f (cities, sub type 0, type <= 0xf)
        - 0x2axx..0x30xx (Food & Drink, Lodging, ...)
        - 0x28xx (no category ?)
        - 0x64xx .. 0x66xx (attractions)
        This option allows to exclude POI types from the index.
        The exclueded types are not indexed, but may still be searchable on a device
        as some devices seem to ignore most of the index, e.g. an Oregon 600 with
        firmware 5.00 only seems to use it for city search.
        If you device finds a POI name like 'Planet' when you search for 'Net'
        it doesn't use the index because the index created by mkgmap cannot help for
        that search.
        So, this option may help when you care about the size of the index or the
        memory that is needed to calculate it.
        The option expects a comma separated list of types or type ranges. A range is
        given with from-type-to-type, e.g. 0x6400-0x6405. First and last type are both
        excluded.A range can span multiple types, e.g. 0x6400-0x661f.
        Examples for usage:
        - Assume your style adds a POI with type 0x2800 for each addr:housenumber.
                It is not useful to index those numbers, so you can use
                --poi-excl-index=0x2800
                to exclude this.
        - For the mentioned Oregon you may use --poi-excl-index=0x2a00-0x661f
                to reduce the index size.


Please suggest improvements.

ciao,
Gerd

Hi Alexandre,

thanks for the hint. The options work fine together. I'll try to make that clearer.

Hi Gerd,

it is clear your documentation for the new --road-name-config parameter. However, what is the relation or impact using this new parameter concomitantly with --x-split-name-index? Are they mutually exclusive?

I suggest to clarify this in the documentation.

Thanks.

Regards,

Alexandre

Hi all,

in r3963 I tried to document the new prefix / suffix stuff:
--road-name-config=file
        This option handles the problem that some countries have road names which
        ofter start or end with very similar words, e.g. in France the first word
        is very often 'Rue', ofter followed by a preposition like 'de la' or 'des'.

        the word 'Concorde' is really interesting. In the USA, you ofter have names
        like 'West Main Street' where only the word 'Main' is important.
        Garmin software has some tricks to handle this problem. It allows to use
        special characters in the road labels which mark the beginning and end of
        the important part.
        There are two different visiual effects of this option:

                or 'Rue du Moulin'. It may list 'Rueben Brookins Road' if that is in the map.

        Another effect is that the index is smaller.

        The option specifies the path to a file which gives the details. See
        comments in the sample roadNameConfig.txt for further details.

Is that clear enough? Please check also the comments in the sample file.
Please suggest improvements, else I'll use the same text for the style documentation before
merging to trunk.
