NAME

yaml_to_db - convert a subset of YAML into fsdb

SYNOPSIS

yaml_to_db <source.yaml

DESCRIPTION

Converts a very limited subset of YAML into Fsdb format.

The input is YAML-format (not fsdb). The input is parsed as YAML, assuming the file is an array of dictionary entries. We extract the dictionary names and output this as an fsdb table.

The output is tab-separated fsdb. (Someday more general field separators should be supported.)

OPTIONS

This module also supports the standard fsdb options:

-d

Enable debugging output.

-i or --input InputSource

Read from InputSource, typically a file name, or - for standard input, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.

-o or --output OutputDestination

Write to OutputDestination, typically a file name, or - for standard output, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.

--autorun or --noautorun

By default, programs process automatically, but Fsdb::Filter objects in Perl do not run until you invoke the run() method. The --(no)autorun option controls that behavior within Perl.

--help

Show help.

--man

Show full manual.
