While Chickadee games are free +software, it would be far too burdensome on the player to ask them to +compile a game from source in order to try it out. Many potential +players will simply not even try. Players expect to be able to +download a compressed archive, extract it, and play. If there are any +more steps than that then the chances of the game being played drop +dramatically. If you can’t beat ’em, join ’em. The +<code>chickadee bundle</code> tool creates redistributable binary bundles +by combining the game code and assets with shared libraries and +executables from the host operating system. +</p> +<p>Bundling is currently only supported on Linux. In the future, it may +be possible to bundle on MacOS. Patches very much welcome for that. +</p> +<p>It should be noted that bundling is a problematic way to distribute +software. All of the libraries that the bundled application includes +are separated from the distribution that was so carefully making sure +that they stay up-to-date with regard to security patches. The +bundled libraries are frozen in time, vulnerabilities and all. +Unfortunately, the release model used by the most popular +distributions, while wonderful for stable, mature software, does not +fit the needs of game distribution at all. So, we compromise, knowing +that most games are only played for only a short amount of time before +being disposed. Perhaps, in time, the Linux world will shift to using +more robust package management solutions such as +<a href="https://guix.gnu.org">GNU Guix</a> which support long-term +maintenance of stable software as well as the “fire and forget” +nature of game releases. And maybe a game made with Chickadee will +become so popular that major distributions decide to package it, but +let’s get back to reality. +</p> +<p>To get started with bundling, simply add a <samp>bundle.scm</samp> file to +the root of the project directory. It could look something like this: +</p> +<div class="example"> +<pre class="example">'((asset-directories . ("images" "models")) + (bundle-name . "the-legend-of-emacs-1.0") + (code . "the-legend-of-emacs.scm") + (launcher-name . "the-legend-of-emacs")) +</pre></div> + +<p>To create the bundle, simply run <code>chickadee bundle</code>. Upon +success, the file <samp>the-legend-of-emacs-1.0.tar.gz</samp> would be +created in the current directory. +</p> +<p>To maximize the chances that the bundle will work on someone else’s +computer, it’s best to build on the oldest supported Linux +distribution available. As of this writing, Ubuntu 18.04 LTS is a +good choice. +</p> +<p>In addition to including system libraries and executables, +<code>chickadee bundle</code> also includes the compiled Guile bytecode +(the <samp>.go</samp> files) for all modules used by the game. The module +source files are <em>not</em> included, so it’s critical that all of the +modules used by the game have been compiled. +</p> +<p>Available options: +</p> +<ul> +<li> <code>asset-directories</code> + +<p>A list of directories that hold static game assets such as images or +audio. Files in these directories will be copied into the bundle +archive. +</p> +</li><li> <code>binary-directories</code> + +<p>A list of directories to search for system binaries, such as +<code>guile</code>. By default, <samp>/usr/bin</samp> is searched. +</p> +</li><li> <code>bundle-name</code> + +<p>The name of the bundle archive. By default, the name is +<code>"chickadee-bundle"</code>. +</p> +</li><li> <code>launcher-name</code> + +<p>The name of the launcher script. By default, the name is +<code>"launch-game"</code>. +</p> +</li><li> <code>libraries</code> + +<p>A list of shared libraries to include in the bundle. By default, all +of the libraries necessary for running Guile, Guile-SDL2, and +Chickadee are included. This list is compatible with the names given +to the libraries on Ubuntu, which may be different than on other +distributions. In such cases, this list will need to be customized. +See below for more information on the <code>%default-config</code> variable +that can be of help. +</p> +</li><li> <code>library-directories</code> + +<p>A list of directories to search for system shared libraries. By +default, the list contains common directories used by most +distributions. +</p> +</li><li> <code>method</code> + +<p>The method by which the game is launched. Can be either <code>play</code> +or <code>manual</code>. The default is <code>play</code>, which means that +<code>chickadee play</code> will be used to launch the game. For games +that do not use <code>chickadee play</code>, opting to start the game +loop on their own, the <code>manual</code> method should be used. +</p> +</li><li> <code>play-args</code> + +<p>A list of command line arguments to pass to <code>chickadee play</code>. +Only used when the <code>method</code> option is set to <code>play</code>. +</p> +</li></ul> + +<p>Default configuration options, such as the list of C shared libaries, +can be found in the <code>%default-config</code> variable. This way they +can be programatically modified, if necessary. +</p> +<dl> +<dt id="index-_0025default_002dconfig">Variable: <strong>%default-config</strong></dt> +<dd><p>An association list of default configuration options. +</p></dd></dl> + +<hr> +<div class="header"> +<p> +Previous: <a href="Invoking-chickadee-play.html" accesskey="p" rel="prev">Invoking chickadee play</a>, Up: <a href="Command-Line-Interface.html" accesskey="u" rel="up">Command Line Interface</a> [<a href="index.html#SEC_Contents" title="Table of contents" rel="contents">Contents</a>][<a href="Index.html" title="Index" rel="index">Index</a>]</p> +</div> + + + +</body> +</html> |
