NAME ^

Uplug - a toolbox for processing (parallel) text corpora

SYNOPSIS ^

  $module = 'pre/basic';
  %args = ( '-in' => $input_file_name,
            '-ci' => $input_char_encoding );

  my $uplug=Uplug->new($module, %args);   # create a new uplug module
  $uplug->load();                         # load it
  $uplug->run();                          # and run it

DESCRIPTION ^

This library provides the main methods for loading Uplug modules and running them. Configuration files describe the module and its parameters (see Uplug::Config). Each module may contain a number of sub-modules. Each of them can usually calls the uplug scripts provided in the package.

USAGE ^

More information on how to use the Uplug toolkit with the provided modules can be found here: uplug

Add-ons and language-specific modules can be downloaded from the Uplug project website at bitbucket: https://bitbucket.org/tiedemann/uplug

Class methods ^

Constructor

 $uplug = new Uplug ( $module, %args )

Construct a new Uplug object for the given Uplug module ($module refers to a configuration file). Module arguments are specified in %args and depend on the module. For more information about specific Uplug modules, use the Uplug startup script:

 uplug -h module-name

load

 $uplug->load()

Load the module given in the constructor and all its sub-modules. This also creates temporary configuration files with adjusted parameters in data/runtime.

run

 $uplug->run()

Run all commands specified in all sub-modules. Pipeline commands will be constructed according to the sequence of sub-modules and the specifications in the Uplug configuration files. The will be simply executed as external system calls.

Class-internal methods ^

loadSubMods

Load all sub-modules and adjust input and output according to the configuration files and the current pipe-line. Output streams will be used as input streams with the same name for the next sub-module. This method tries to find possible pipelines for combining commands.

command

 $cmd = $uplug->command()

Return a sequence of system commands for the entire pipeline. Commands are separated by ';'. System command may include several pipelines through STDIN/STDOUT.

input

Change the input settings in a particular configuration.

output

Change the output settings in a particular configuration.

data

Set/return data files available in the current pipeline.

stdin

Check whether their is an input stream that can read from STDIN.

stdout

Check whether their is an output stream that can write to STDOUT.

FileInUse

Checks whether a particular file is already in use in the current pipeline (avoids writing over files that a command still reads from).

NewTempFile

Return a new temporary file (in data/runtime).
