convert IMPORTER [OPTIONS] [[--fix FIX]] to EXPORTER [OPTIONS]

Convert data from one format to another format with help of Catmandu::Importers and Catmandu::Exporters. All options given on the command line will be send to the Importer or Exporter as initialization parameters. E.g.

 catmandu convert OAI --url BASEURL --metadataPrefx PREFIX \
                  to \
                  CSV --header 1 --sep_char '|'

Look at the documentation of all the importers and exporters to see which options are available.

All importers accept one or more --fix options with the name of a fix file or file command.

 catmandu convert JSON --fix fixes.txt
 catmandu convert JSON --fix 'remove_field(abc)'

The JSON exporter is implicit and is optional.

 catmandu convert YAML to JSON  
 catmandu convert YAML # shorter

count STORE [OPTIONS]

Count the number of items in a Catmandu::Store. All options given on the command line will be send to the store as initialization parameters. E.g.

 catmandu count MongoDB --database_name mydb --bag data

delete STORE [OPTIONS] [-q QUERY]

Delete items from a Catmandu::Store. All options given on the command line will be send to the store as initialization parameters. Optionally a QUERY can be provided to select the items to delete. E.g.

 catmandu delete MongoDB --database_name mydb --bag data -q "title:Delete me"

export STORE [OPTIONS] [-q QUERY] [--limit LIMIT] [[--fix FIX]] to EXPORTER [OPTIONS]

Export items from a Catmandu::Store using a Catmandu::Exporter. All options given on the command line will be send to the Store or Exporter as initialization parameters. Optionally a QUERY and LIMIT can be provided to selectively export items from the Store. Optionally a FIX can be provided to be executed on all the items before they are exporter by the exporter.

E.g.

 catmandu export MongoDB --database_name mydb --bag data -q "title:Perl"

import IMPORTER [OPTIONS] [[--fix FIX]] to STORE [OPTIONS]

Import items from a Catmandu::Importer to a Catmandu::Store. All options given on the command line will be send to the Importer or Store as initialization parameters. Optionally a FIX can be provided to be executed on all the items before they are stored into the Store.

 catmandu import JSON to MongoDB --database_name mydb < records.json

move STORE [OPTIONS] [-q QUERY] [--limit LIMIT] [[--fix FIX]] to STORE [OPTIONS]

Move items from one Catmandu::Store to another. All options given on the command line will be send to the Stores as initialization parameters. Optionally a QUERY and LIMIT can be provided to selectively export items from the Store. Optionally a FIX can be provided to be executed on all the items before they are stored.

data [LONG_OPTIONS]

Low level data manipulation command. See DATA OPTIONS below for full documentation.

OPTIONS

-v

Verbose output. This includes progress of operations.

-h

-?

--lib-path PATH

-I

Specifies Perl library include paths, like perl's -I option. This option is repeatable.

--load-path PATH

-L PATH

Search upwards from this path for configuration files and accompanying lib directories. This option is repeatable.

--debug [LEVEL]

-D[LEVEL]

Set the debugging level for Catmandu. LEVEL is one of:

    1 - WARN messages
    2 - INFO messages
    3 - DEBUG messages

Requires an installation of Log::Log4perl and Log::Any::Adapter::Log4perl. By default an internal log4perl configuration file is used that sends all debug messages to stderr. Optionally in the catmandu.yml the path to a log4perl configuration file can be set. E.g.

    catmandu.yml:
    log4perl: /etc/log4perl.conf
    or
    log4perl: "
     log4perl.category.Catmandu=$level,$appender
         log4perl.appender.STDOUT=Log::Log4perl::Appender::Screen
         log4perl.appender.STDOUT.stderr=0
         log4perl.appender.STDOUT.utf8=1
         log4perl.appender.STDOUT.layout=PatternLayout
         log4perl.appender.STDOUT.layout.ConversionPattern=%d [%P] - %p %l %M time=%r : %m%n
         log4perl.appender.STDERR=Log::Log4perl::Appender::Screen
         log4perl.appender.STDERR.stderr=0
         log4perl.appender.STDERR.utf8=1
         log4perl.appender.STDERR.layout=PatternLayout
         log4perl.appender.STDERR.layout.ConversionPattern=%d [%P] - %l : %m%n
    "

See also Catmandu::Logger to enable logging for your own Catmandu packages.

DATA OPTIONS

These low level options are available to the ``catmandu data'' command.

--from-store STORE

Read items from a Catmandu::Store such as: DBI, MongoDB, Solr, ElasticSearch, ...

--from-importer IMPORTER

Read items from a Catmandu::Importer such as: YAML, JSON, CSV, MARC, OAI ...

--from-bag BAG_NAME

This option should be used in combination with a --from-store. Select from the Store only the items belonging to the bag BAG_NAME.

--from-OPTION OPTION_VALUE

To include configuration options to a Catmandu::Store or Catmandu::Importer an argument with prefix '--from-' can be used. E.g. to provide an 'file' to an Importer use:

  --from-file /my/path/to/file.txt

--into-exporter EXPORTER

Add each item read into a Catmandu::Exporter such as: JSON, YAML, Template, XLS, ...

--into-store STORE

Add each item read into a Catmandu::Store such as: DBI, MongoDB, Solr, ElasticSearch, ...

--into-bag BAG_NAME

This option should be used in combination with a --into-store. Add each item into the Store with bag BAG_NAME.

--into-OPTION OPTION_VALUE

To include configuration options to a Catmandu::Store or Catmandu::Exporter an argument with prefix '--into-' can be used. E.g. to provide an 'file' to an Exporter use:

  --into-file /tmp/file.txt

--fix EXPRESSION

--fix FILE

When exporting or storing apply a fix EXPRESSION or all the fixes in FILE on each item. This option is repeatable. FILE can also be an arbitrary executable if Catmandu::Fix::cmd is installed.

--start NUM

When exporting or storing data skip the first NUM items.

--total NUM

When exporting of storing data process only a total NUM of items.

--replace

When storing data first delete all the items in the Store or Bag.

--query QUERY

--cql-query QUERY | -q QUERY

When a Store is searchable execute and return the results. Using the --cql-query or -q option the CQL query language can be used (if supported).

--limit NUM

Limit the number of results returned from the searchable results to NUM.

--count

Report the number of items processed.
