                   NoSQL operator: nblparser

NoSQL Brokering Language (NBL) interpreter

Usage: nblparser schema [options]

Options:
    --input (-i) 'file'
      Read input NBL statements from 'file' instead of STDIN.

    --output (-o) 'file'
      Write output sh(1) script to 'file' instead of STDOUT.

    --unsafe (-U)
      Accept unsafe NBL directives, i.e. 'system'.
      By default unsafe directives are refused.

    --delete (-d) 'n'
      Remove temporary files created by 'remember-as' after 'n' seconds.
      By default they are deteted after the default delay applied by
      the 'tmptable' operator.

    --no-hide (-n)
      Ignore any 'Hide' field contents in the schema table.

    --help (-h)
      Display this help text.

Notes:

Takes a database schema table on the command-line, and a batch of NBL
statements on STDIN, and produces a sh(1) script with the corresponding
NoSQL pipeline of commands.

Here is an example usage at the command-line:

              nblparser schema.rdb < input.nbl | sh
