_USAGE = _("""
Example of usage of Gramps command line interface

1. To import four databases (whose formats can be determined from their names)
and then check the resulting database for errors, one may type:
gramps -i file1.ged -i file2.gpkg -i ~/db3.gramps -i file4.wft -a tool -p name=check. 

2. To explicitly specify the formats in the above example, append filenames with appropriate -f options:
gramps -i file1.ged -f gedcom -i file2.gpkg -f gramps-pkg -i ~/db3.gramps -f gramps-xml -i file4.wft -f wft -a tool -p name=check. 

3. To record the database resulting from all imports, supply -e flag
(use -f if the filename does not allow Gramps to guess the format):
gramps -i file1.ged -i file2.gpkg -e ~/new-package -f gramps-pkg

4. To save any error messages of the above example into files outfile and errfile, run:
gramps -i file1.ged -i file2.dpkg -e ~/new-package -f gramps-pkg >outfile 2>errfile

5. To import three databases and start interactive Gramps session with the result:
gramps -i file1.ged -i file2.gpkg -i ~/db3.gramps

6. To open a database and, based on that data, generate timeline report in PDF format
putting the output into the my_timeline.pdf file:
gramps -O 'Family Tree 1' -a report -p name=timeline,off=pdf,of=my_timeline.pdf

7. To generate a summary of a database:
gramps -O 'Family Tree 1' -a report -p name=summary

8. Listing report options
Use the name=timeline,show=all to find out about all available options for the timeline report.
To find out details of a particular option, use show=option_name , e.g. name=timeline,show=off string.
To learn about available report names, use name=show string.

9. To convert a Family Tree on the fly to a .gramps xml file:
gramps -O 'Family Tree 1' -e output.gramps -f gramps-xml

10. To generate a web site into an other locale (in german):
LANGUAGE=de_DE; LANG=de_DE.UTF-8 gramps -O 'Family Tree 1' -a report -p name=navwebpage,target=/../de

11. Finally, to start normal interactive session type:
gramps

Note: These examples are for bash shell.
Syntax may be different for other shells and for Windows.

[docs]class ArgParser(object): """ This class is responsible for parsing the command line arguments (if any) given to gramps, and determining if a GUI or a CLI session must be started. A filename and/or options may be specified as arguments. The valid options are: -O, --open=FAMILY_TREE Open Family Tree -C, --create=FAMILY_TREE Create on open if new Family Tree -i, --import=FILENAME Import file -e, --export=FILENAME Export file -f, --format=FORMAT Specify Family Tree format -a, --action=ACTION Specify action -p, --options=OPTIONS_STRING Specify options -d, --debug=LOGGER_NAME Enable debug logs -l List Family Trees -L List Family Trees in Detail -t List Family Trees, tab delimited -u, --force-unlock Force unlock of Family Tree -s, --show Show config settings -c, --config=SETTINGS Set config setting(s) and start Gramps -y, --yes Don't ask to confirm dangerous actions -q, --quiet Suppress progress indication output -v, --version Show versions -h, --help Display the help --usage Display usage information If the filename (no options) is specified, the interactive session is launched using data from filename. In this mode (filename, no options), the rest of the arguments are ignored. This is a mode suitable by default for GUI launchers, mime type handlers, and the like. If no filename or -i option is given, a new interactive session (empty database) is launched, since no data is given anyway. If -O or -i option is given, but no -e or -a options are given, an interactive session is launched with the ``FILENAME`` (specified with -i). If both input (-O or -i) and processing (-e or -a) options are given, interactive session will not be launched. When using import ot export options (-i or -e), the -f option may be specified to indicate the family tree format. Possible values for ``ACTION`` are: 'report', 'book' and 'tool'. Configuration ``SETTINGS`` may be specified using the -c option. The settings are of the form config.setting[:value]. If used without a value, the setting is shown. If the -y option is given, the user's acceptance of any CLI prompt is assumed. (see :meth:`.cli.user.User.prompt`) If the -q option is given, extra noise on sys.stderr, such as progress indicators, is suppressed.
