very very simple CGI library for gcc-Ada (GNAT)

Introduction

Web

It contains the simple subprograms for CGI, e.g. getting the environment variables, parsing QUERY_STRING, the form data, and the cookies, writing the HTTP headers, etc.

Web.HTML

It contains the helpers for writing escaped text into HTML, etc.

Web.Producers

It's a page producer to write HTML from the template file. Special tags in the template file will be notified to the callback procedure.

<?TAG/>

You can replace it to any HTML written in callback.

<?TAG>CONTENTS</?TAG>

You can use CONTENTS as a sub-template for recursive or ignore. The sub-template is just as or part of CONTENTS.

example:

<?TAG>XXX<?SUBA>AAA</?SUBA><?SUBB>BBB</?SUBB>YYY</?TAG>

It can select all (XXX to YYY), extract SUBA (AAA) or SUBB (BBB), repeat these, or ignore all.

<a ?TAG>

Attribute-style special tag. And, any normal attributes after it will be removed and saved as the content of the sub-template. It's usable to preview with your web browser.

example:

<link rel="stylesheet" type="text/css" ?APPCSS href="sample.css" />

It uses sample.css when this template is directly opened in the browser, and it can select whether to replace the parts after the placeholder (APPCSS href="sample.css") with another style sheet, or use the content (href="sample.css") as is.

Web.RSS

It's a very very simple RSS 2.0 writer.

Web.Lock_Files

It's a filesystem-based interprocess mutex. There are the simple subprograms and the RAII-style object.
