gedcom

A general purpose utility for gedcom files. This program does a lot of different things with a gedcom file.

Print today's family anniversaries

Given your family tree as a gedcom, gedcom will tell you whose birthday it is and who died on this day. Although primarily a tool for genealogy, the -l flag tells gedcom to include matches for family members that are still alive.

The -d flag will give you a short biography of each person.

Try adding this to your crontab, it will give you a daily e-mail of your relative's birthdays and the anniversaries of their death along with information about their life.

3 5 * * * gedcom -dl gedcom-file.ged

or

22 5 * * * gedcom -dth 'Your Full Name' gedcom-file.ged

Gedcom validation

Gedcom also includes sanity checking and validation of your Gedcom file, including missing, impossible and inconsistent information allowing for greater error correction. Date formats are standardized and duplicate people are detected. You can enable this mode with -w, which will print warnings of anything it finds. It's a sort of lint for Gedcom files.

For example:

gedcom -dAwWl gedcom-file.ged > /dev/null

Adding the -c option will add the checking of missing citations.

To sort by error type:

gedcom -dAwWl gedcom-file.ged > /dev/null 2> /tmp/errs
sort -t: -k2 /tmp/errs

Genealogy Calendar

You can create a month-to-a-page genealogical calendar of your ancestors:

for i in 1 2 3 4 5 6 7 8 9 10 11 12
do
    gedcom -dwHm $i -y $(date +%Y) gedcom-file.ged > $i.html
done

To print a month-to-a-page calendar of all the Smiths in your tree as a present, choose any Smith in your tree as a home person so that the -s option works:

for i in 1 2 3 4 5 6 7 8 9 10 11 12
do
    gedcom -dwHlm $i -y $(date +%Y) -h 'John Smith' -s gedcom-file.ged > $i.html
done

Alternatively you can create an ICS file to import to Google Calendar:

gedcom -i /tmp/ics.ics gedcom-file.ged

Produce a Google Map

You can produce a map of locations of all Smiths in your tree with

gedcom -xsh Smith gedcom-file-ged > smith.csv

• Upload the csv file to Google Drive
• Visit google.com/maps, on the 3 horizontal lines choose "your places" ("Vos adresses"), then "maps" ("Cartes")
• Click "create map", choose "import" and upload your file, choose "Location" as the position column and "People" as the title column
• You may see that a number of rows can't be seen in the map, this is an opportunity to find locations in your map that are incorrect

Family History Book

You can create a genealogy book as a PDF of your family history and research to give to your dad on father's day:

# Note that this will only print people related to your father, even if you give -a
# yum install gd-devel ImageMagick-devel
gedcom -B family-history.pdf -dh "Your Father's Full Name" gedcom-file.ged

You can create a book of your family name based on the descendants of John Smith:

gedcom -GB smith.pdf -dsh 'John Smith' gedcom-file.ged

If you enable the -w flag with the -B option, warnings will appear in red in the book.

-y: year for -H calendar, or -T to give a list of places for a specific year

Running on Windows

• Firstly, if you're running Windows 10, install Ubuntu or install Perl directly, either ActiveState or Strawberry should work fine. I have also had success using Cygwin's Perl.

• Next follow the instructions at local::lib.

• Load in all the CPAN modules that gedcom uses. If you're not sure, run gedcom with no arguments and the program will install its core modules to get started.

Bugs

There will be numerous strange handling of Gedcoms since it's not that tightly observed by websites. If you see lumpy English text in the output, or just plain mistakes, please e-mail me or add a bug report to github.com/nigelhorne/gedcom.

I've tested against a number of Gedcoms including the Torture Tests at https://www.tamurajones.net/DownloadTortureTests.xhtml and gedcoms from gedcomlibrary.com.

With the -T option, countries and counties can be optimized out. That will be fixed.

Different people use different ways to format and enter information, ged2site goes out of its way to support all of these, such as different location and date formats. If your data shows issues with this aim, let me know.

The story telling format is hard coded, it would be useful if it were configurable.

Pre-Requisites

Gedcom uses many CPAN modules which it will try to install if they are not on your system. If it doesn't have the necessary privilege to install the modules it will fail on starting up with "permission denied" errors. This is most likely because you're not running as root (which is of course how it should be) and you're not using local::lib, or Perlbrew.

Running the program for the first time with no arguments should install them, of course that will fail if you don't have the privilege, in which case you'll need to add them by hand. To install by hand you'll either have to use local::lib or perlbrew. Of course you could also run gedcom as root, but I strongly advise you don't do that.

You can also try cpan -i lazy && perl -Mlazy gedcom though I've not tested that.

To use the -B option on FreeBSD you'll need to "sudo pkg install pkgconf gdlib ImageMagick7; cd /usr/local/lib; sudo ln -s libMagick++-7.so libMagickCore-7.Q16HDRI.so"

To use the -M option on FreeBSD you'll need to "sudo pkg install apngasm"

Acknowledgements

So many Perl CPAN modules that if I list them all I'll miss one, but special mention goes to the Gedcom module.
