Commands:
help Displays this message.
System commands:
load Load Pokédex data into a database from CSV files.
dump Dump Pokédex data from a database into CSV files.
- setup Loads Pokédex data into the right place and creates a
- lookup index in the right place. No options or output.
- This will blow away the default database and index!
+ reindex Rebuilds the lookup index from the database.
+ setup Combines load and reindex.
+ status No effect, but prints which engine, index, and csv
+ directory would be used for other commands.
-Options:
- -d|--directory By default, load and dump will use the CSV files in the
+Global options:
+ -e|--engine=URI By default, all commands try to use a SQLite database
+ in the pokedex install directory. Use this option (or
+ a POKEDEX_DB_ENGINE environment variable) to specify an
+ alternate database.
+ -i|--index=DIR By default, all commands try to put the lookup index in
+ the pokedex install directory. Use this option (or a
+ POKEDEX_INDEX_DIR environment variable) to specify an
+ alternate loction.
+ -q|--quiet Don't print system output. This is the default for
+ non-system commands and setup.
+ -v|--verbose Print system output. This is the default for system
+ commands, except setup.
+
+System options:
+ -d|--directory=DIR By default, load and dump will use the CSV files in the
pokedex install directory. Use this option to specify
a different directory.
-D|--drop-tables With load, drop all tables before loading data.
- -e|--engine=URI By default, all commands try to use a SQLite database
- in the pokedex install directory. Use this option to
- specify an alternate database.
- -q|--quiet Turn off any unnecessary status output from dump/load.
+
+ Additionally, load and dump accept a list of table names (possibly with
+ wildcards) and/or csv fileames as an argument list.
