    <h1>PythonCard standaloneBuilder tool</h1>
    </div>
    <?php include "sidebar.php" ?>
    <div id="content">
    <h2>Introduction</h2>
    <p>The process of converting a PythonCard project into a stand-alone application,
    complete with installer and un-install entry, is fairly tedious to do 'by
    hand'. Whilst writing some documentation (see <a href="standalone.html">here</a>) to
    cover this, it became clear that there was a need for some application
    software (written using PythonCard, naturally!) to help automate the process. The
    <i>standaloneBuilder</i> tool is the result. The program offers the user the
    ability to manage the development and release of successive versions of an
    application project written using PythonCard.</p>

    <p>Comments on this document and/or bug reports related to the <i>standaloneBuilder</i> tool
    may be posted to the PythonCard users mailing list, <a href="http://lists.sourceforge.net/lists/listinfo/pythoncard-users">http://lists.sourceforge.net/lists/listinfo/pythoncard-users</a>, for discussion.</p>

	<h2>Pre-Requisites</h2>
	<p>As well as Python, wxPython and PythonCard, you will need to have installed and configured
	McMillan Installer and Inno Setup on your computer. These packages can be downloaded from
	the following locations as of the time of writing:
	<ul>
		<li>McMillan Installer: <a href="http://paulbaranowski.org/modules.php?name=Downloads&d_op=getit&lid=8">http://paulbaranowski.org/modules.php?name=Downloads&d_op=getit&lid=8</a></li>
		<li>Inno Setup: <a href="http://www.jrsoftware.org/isdl.php">http://www.jrsoftware.org/isdl.php</a></li>
	</ul>
	Both packages come with comprehensive documentation - installation and setup should be
	painless.</p>

	<h2>Configuring <i>standaloneBuilder</i></h2>
	<p>When launching <i>standaloneBuilder</i> for the first time, it detects that the
	preferences need to be configured and drops you straight into the preferences
	dialog.</p>
	<div align="center"><img src="pic1.jpg" /></div>
	<p>You can come back to this dialog at any time by clicking the preferences
	button on the main screen. All of the options have help buttons (marked with
	'?') associated with them, so you can (hopefully) figure out what each one is
	for without too much difficulty. The program will try to find as much information as it
	can, you should only need to tell it your name and where to find the directory
	you keep all your projects in.</p>
	<div align="center"><img src="pic2.jpg" /></div>

	<p>After filling in any missing information, click the OK button to save your
	preferences for use In future projects.

	<h2>Creating a new project</h2>

	<p>For the purposes of this
	document, we'll use the <i>standaloneBuilder</i> tool in conjunction with the
	application created in <a href="walkthrough2.html">walkthrough #2,</a> to illustrate
	the steps involved in the creation, development and distribution of a typical PythonCard
	program. We'll assume that you have already followed the walkthrough and you have the
	<i>counter.py</i> application fully functional.</p>

	<div align="center"><img src="pic3.jpg" /></div>

	<p>To begin, click on the 'New' button to start the new project wizard and fill
	in the details as required:</p>
	<div align="center"><img src="pic4.jpg" /></div><br />
	<div align="center"><img src="pic5.jpg" /></div><br />
	<div align="center"><img src="pic6.jpg" /></div><br />
	<div align="center"><img src="pic7.jpg" /></div><br />
	<div align="center"><img src="pic8.jpg" /></div><br />

	<p>After completing the new project wizard, the program will create the project
	and add in some default folders and template files. A 'save' dialog will then
	be presented to allow the project details to be written to disk. The main
	window will now appear as shown below:</p>

	<div align="center"><img src="pic9.jpg" /></div>

	<h2>Adding files to the project</h2>
	<p>The first step will be to define the main script file for the project. In this case,
	there is only one script, namely <i>counter.py</i>, so click the '...' button next to
	the main script file text field. Navigate to the <i>sab-demo</i> folder and select the
	'counter.py' script. Click the Open button to add it to the project:</p>

	<div align="center"><img src="pic10.jpg" /></div><br />
	<div align="center"><img src="pic11.jpg" /></div>

	<p>A note is probably in order at this point about the <i>Script files</i> box. Generally,
	McMillan Installer is quite good at working out if there are any additional source files
	associated with the main script, simply by examining any <i>import</i> lines in the
	source code. This may appear to make the <i>Script files</i> box largely superfluous. If
	you intend to only ever build projects for Windows platforms, then you may well find that
	you never need to explicitly list any additional script files. If, however, you also want
	to distribute your project to Linux users, then things are slightly different. When running
	<i>standaloneBuilder</i> on Linux, the rebuild button simply builds a compressed tar file
	containing the items you have specified as making up your project. In this scenario, only
	those files that you have explicitly listed will be included in the tar file. Also, by
	including your script files explicitly, the usefulness of <i>standaloneBuilder</i> as a
	general purpose project manager comes into play. You can edit a given script file by
	simply selecting it in the list and clicking the <i>Edit...</i> button.</p>

	<p>Now, under the <i>Resource files</i> section of the main window, click the Add button.
	Select the <i>counter.rsrc.py</i> file and click on Open. This adds the resource file
	into the project:</p>

	<div align="center"><img src="pic12.jpg" /></div>

	<p>Having added the resource file, you can now open it in the resource editor simply by
	clicking on the Edit button on the main window. Files which are added in other sections
	of the main window can be edited in the same way. Script files will be opened using the
	program defined as the text editor in preferences. This defaults to the PythonCard code
	editor, but can be changed if required. Files listed under the Pixmaps section will
	be opened using whatever you specify as your default image editor in preferences,</p>

	<h2>Project properties</h2>
	<p>That pretty much covers the mechanics of adding and editing the files which make up
	your project. The project properties dialog provides a number of options which affect
	how the final standalone version of your program is built. To access this, click the
	Properties button on the main window:</p>

	<div align="center"><img src="pic13.jpg" /></div>

	<p>The first few fields determine the folder layout within your project. All the paths
	used within standaloneBuilder are relative. For example, the default build directory
	is simply called 'build' - in practice, this folder would be created in whatever you
	specified as the base folder when the project was initially created, this would in turn
	be created as a sub folder of your top level 'projects' folder defined in the
	preferences. Thus, in this example:</p>

	<ul>
		<li>Projects folder in preferences is <i>P:\</i></li>
		<li>The project was created in a folder called <i>sab-demo</i></li>
		<li>The build directory is called simply <i>build</i></li>
	</ul>

	<p>The full path to the build directory is therefore <i>P:\sab-demo\build</i>. Having
	all of the folder references relative to each other allows <i>standaloneBuilder</i>
	to maintain projects on both Windows and Linux platforms, with Python itself taking
	care of the differences in path separators.</p>

	<p>The application publisher, application URL and application licence fields are
	used by Inno Setup when the final version of the program is built</p>

	<p>The other options from <i>Deployment type</i> onwards correspond to the same
	options in the McMillan Installer. Note that new projects are always created with
	the <i>Console</i> option turned on - this is intended to aid with debugging. The
	build process generates a warning message to remind you to turn this off before making
	a release of your finished application.</p>

	<h2>Changelog & README buttons</h2>
	<p>Clicking the Changelog button launches the text editor defined in preferences and
	opens the project changelog file for further editing:</p>

	<div align="center"><img src="pic14.jpg" /></div>

	<p>Additional entries can be made directly using this option. Alternatively, there
	is an 'add changelog entry' option on the 'tools' menu. This pops up a small text
	entry dialog like so:</p>
	<div align="center"><img src="pic15.jpg" /></div>
	<p>The entry then gets added to the changelog. Entries are made so that the
	most recently added is at the top:</p>
	<div align="center"><img src="pic16.jpg" /></div>

	<p>The README button does a similar thing, but instead uses the text editor
	to open a file called <i>readme.txt</i> in the project base folder</p>

	<h2>The Run Button</h2>
	<p>When clicked, the <i>Run...</i> button executes the main script of your project. It firstly pops
	up a small dialog wherein you can specify a number of useful command line options:</p>
	<div align="center"><img src="pic28.jpg" /></div>
	<p>There must be a reason why this looks suspiciously like the run-time options dialog
	from the PythonCard resource editor, but I'm sure I couldn't even begin to guess what
	that reason might be... :-)</p>

	<h2>The Rebuild button</h2>
	<p>Clicking this button causes the standalone version of your application to be rebuilt. As
	<i>sab-demo</i> is a new project, it has been created with the console option switched on.
	The first thing <i>standaloneBuilder</i> does is to remind you about this:</p>
	<div align="center"><img src="pic17.jpg" /></div>
	<p>The build then proceeds. If all is successful, the program will tell you where it has
	stored the installer for the project:</p>
	<div align="center"><img src="pic18.jpg" /></div>
	<p>A scrolling text window is also displayed where you can see the output from the
	build process:</p>
	<div align="center"><img src="pic19.jpg" /></div>
	<p>When the build has completed, the self extracting installer executable can be
	copied to another Windows machine ad run. The resulting setup wizard looks the same
	as virtually any other piece of 'professionally' produced software:</p>
	<div align="center"><img src="pic21.jpg" /></div>
	<p>The executable itself looks and behaves exactly the same as any other program. This
	is the result of right-clicking the <i>sab-demo.exe</i> file and selecting 'Properties':</p>
	<div align="center"><img src="pic20.jpg" /></div>

	<h2>The Release button</h2>
	<p>When you are happy that you have thoroughly debugged your project and are ready to
	release it to the outside world, you should open the project in <i>standaloneBuilder</i>
	and click the Release button. Doing this puts the current release of the project into
	a <i>frozen</i> state, in which no further changes can be made until you have checked and
	confirmed that the release is okay.</p>

	<p>The first thing that happens upon clicking the Release button is that a warning dialog
	pops up to give you the option of changing your mind:</p>
	<div align="center"><img src="pic22.jpg" /></div>

	<p>Assuming that you click OK at this point, a number of things then happen to the project.
	Firstly, the status gets changed from <i>Open</i> to <i>Frozen</i> and the majority
	of the controls on the main window get disabled:</p>
	<div align="center"><img src="pic23.jpg" /></div>
	<p>Secondly, the 'release date TBA' tag at the top of the project changelog gets replaced
	by the current date. At this point, only the <i>Rebuild</i> and <Release</i> buttons
	will work. You should carry out a final rebuild of your project under both Windows and
	Linux, if applicable. Under Linux, the <i>Rebuild</i> process simply produces a TAR archive
	of the files which make up your project, as opposed to a standalone binary executable.</p>

	<p>When you are happy that everything has been rebuilt as you need it, you are ready to
	close off the current release and start the next version of your project. To do this, just
	click the <i>Release</i> button again. You will be presented with this dialog:</p>
	<div align="center"><img src="pic24.jpg" /></div>
	<p>Click OK to confirm the release. You then have an opportunity to decide what the next
	version number of your project will be, with the option to override what the program offers
	as a deafult. In the example shown below I have decided that the next release of the
	<i>sab-demo</i> project should have a version number of 0.9.1:</p>
	<div align="center"><img src="pic25.jpg" /></div>
	<p>The main window is then refreshed. The build number has been reset to 1 and a new
	changelog entry has been added to indicate the start of the release cycle for the new
	version number:</p>
	<div align="center"><img src="pic26.jpg" /></div><br />
	<div align="center"><img src="pic27.jpg" /></div>
