NAME

htspell - an application built using Navegante

SYNOPSIS

Build the application:

  $ navegante examples/htspell

Use the newly created file htspell as a CGI.

DESCRIPTION

This application behaves as a CGI and it checks in a dictionary if the word exists. The application keeps track of words not found. On every request we also use the banner live feedback section to present some information about the number of not found words. The specific DSL section is:

  cginame(./htspell)
  formtitle(Spell Checking Tool)
  proc(htspellFunction)
  desc(htspellDesc)
  init(htspellInit)
  feedback(htspellFeedback)
  livefeedback(htspellLive)

MODULES

Text::Aspell

Module Text::Aspell was used to check for words in a dictionary.

VARIABLES

Some variables were used so that we can present information about the number of words processed with every request.

$processed

This variable keeps tracks of the total of processed words in every request.

$found

This variable keeps track of the number of found words in the dictionary.

$not_found

This variable keeps track of the number of found not words in the dictionary.

FUNCTIONS

htspellDesc

This function prints the description of the application. This is defined in the DSL by the desc statement.

htspellFunction

This function is used to process the page content. We are checking for words in the dictionary, we are pushing words not found to the special variable estado in order to keep track of not found words over sequential requests. We are also updating counters, like the number of processed or not found words.

XXX _loadit

htspellLive

This is the function that prints the HTML that feeds the banner section for reporting information. This is defined in the DSL by the livefeedback statement. Here we print information about the number of not found words for every page viewed.

htspellInit

This function runs on the beginig of every request and it's used here to reset word counters and create an Aspell object for word checking. This is defined in the DSL by the init statement.
