Usage

Online

Codex to HelpHub: http://unofficialtokyo.com/codex-converter

Codex Translator Aid Tool (Beta): http://unofficialtokyo.com/codex-translater-aid

Click center button for demo.
Cut and Paste the Codex text into the left box and click center button.
Refer "TODO" that requires post production (ex. Image paste).
Code is always assumed as PHP. Adjust the line [code lang=php].
Check whole contents. This program is not complete converter.

Command line

You can convert on your local computer.

Codex to HelpHub:

php command-codextohelphub.php -i <input_file> -o <output_file>

Log

Refer codex-converter.log. To change log file name or log level, edit class-logger.php direct.

logger

codex-converter uses own Logger class only for a removal of external library dependency. That has the same interface with log4php with limitations.

Not ussing log-config.xml. To change log file name or log level, edit class-logger.php direct.
Terrible performance when LOGGERLEVEL_TRACE is set for long Codex article. Use only for debug or consider to use log4php.

log4php

You should use log4php if it is possible.

To use log4php

replace require_once in class-codex.php
rename sample-log-config.xml to log-config.xml

Restriction

Codex to HelpHub:

<pre> tag or line begin with space character is always converted to [code language="php"].

Codex Translater Aid Tool (Beta):

Japanse support only.
Some functions are not implemented yet such as automatic retrieve function by URL specification. Refer ToDo.

Deployment

Codex to HelpHub Deployment steps are as following. Codex Translator Aid tool is the same except file name.

Web Application

Copy every files under the codex-converter/src including sub-directory to Web Server. In this scenario, let's assume files are copied to htdocs/ws-codex-converter.
Edit TARGET_URL in codex-converter.js to point the ws-codex-converter.php. For example, it is var TARGET_URL = 'ws-codex-converter.php'; or var TARGET_URL = '/ws-codex-converter/ws-codex-converter.php';
Access http://(your-host)/ws-codex-converter/codextohelphub.html

Custom Page Template

Even Custom Page Template, first try above "Web Application" step for confirmation.NOTE: Specify absolute path to TARGET_URL in codex-converter.js as the first step, if you get error "XMLHttpRequest : 404, textStatus : error, errorThrown : undefined".
Copy following files to your theme directory

Test

It assumes phpunit can be invoked.

Runs all test at once

testrun

Runs specific test

testrun test01 (or test02, test03, ...)

For test case details, refer tests/CodexHelpHubTest.php.

Customization of Converter

If you want to create your own converter, follow below steps:

Define your converter symbol (ex. KoCodex)
Create subdirectory and class file with lower characters of converter symbol (ex. kocodex/class-kocodex-converter.php)
Implements interface-converter.php. Refer helphub/ or jacodex/. (ex. KoCodexConverter class)
Instantiate Codex class with the converter symbol.

$codex_to = new Codex( 'KoCodex' );
$output_data = $codex_to->convert( $input_data );
