click-flatten

removes compound elements from a Click configuration

Synopsis

click-flatten [options] [param=value ...] [router-file]

Description

The click-flatten tool flattens a Click router configuration, compiling all its compound elements away, and writes the resulting configuration to the standard output. It can also output information about the file.

Options

If any filename argument is a single dash "-", click-flatten will use the standard input or output instead, as appropriate.

  • -c, --classes

    Output an alphabetical list of the element classes used by the flattened router file, one per line, instead of the usual configuration.

  • -n, --elements

    Output an alphabetical list of the element names in the flattened router file, one per line, instead of the usual configuration.

  • -d, --declaration

    Output the element declarations in the flattened router file, one per line, instead of the usual configuration.

  • -f, --file file

    Read the router configuration to flatten from file. The default is the standard input.

  • -e, --expression expr

    Use expr, a string in the Click language, as the router configuration to flatten.

  • --config

    Output flattened configuration only -- if the input was an archive, ignore other archive elements.

  • --expand-vars

    Expand global variables. By default, click-flatten does not expand global variables into configuration strings, allowing later operations, such as click-install, to override their values.

  • -o, --output file

    Write the flattened router configuration to file. The default is the standard output.

  • --help

    Print usage information and exit.

  • --version

    Print the version number and some quickie warranty information and exit.
