To learn what is an extension, see [[Documentation/Nightly/Developers/FAQ#What_is_an_extension_.3F|here]]

== Conventions ==

* Terminal command - Block like the one below indicates that the command should be executed in a terminal.

<ol style="list-style-type:none; border-left:thick solid darkgreen; padding-left:1em;">
<li>On '''Windows''', Git Bash is expected (not the Windows command line). [https://help.github.com/articles/set-up-git#platform-windows Need help ?]</li>

== Step-by-step: How to create, publish and distribute an extension ? ==

<ol start="1" style="list-style-type: decimal;">

<li>Scan through the [[Documentation/{{documentation/version}}/FAQ/Extensions|user]] and [[Documentation/{{documentation/version}}/Developers/FAQ/Extensions|developer]] extension FAQs</li>

<li>(Optionally) Present your extension(s) on the [http://massmail.bwh.harvard.edu/mailman/listinfo/slicer-devel slicer developers list] to check if other developer are working on a similar project, to seek for advice or to reach out for potential collaborator.</li>

<li>[[Documentation/{{documentation/version}}/Developers/Build_Instructions|Build Slicer application]] in <code>Release</code></li>

<li>Use the Wizard to create an extension bundling one Command line module:

{{pre2|<nowiki>
$ cd Slicer-SuperBuild/Slicer-build

$ bin/slicerExtensionWizard --create Slicer-MyExtension --addModule cli:MyCLI ~
</nowiki>}}

<ol style="list-style-type:none; border-left:thick solid darkgreen; padding-left:1em;">
<li>By specifying <code>~</code> as destination, the extension will be created into your home directory.</li>
<li>Read our [[Documentation/{{documentation/version}}/Developers/FAQ/Extensions#Should_the_name_of_the_source_repository_match_the_name_of_the_extension_.3F|FAQ]] to learn about extension naming convention.

: the ExtensionWizard capabilities, click [[Documentation/{{documentation/version}}/Developers/ExtensionWizard|here]].
: the different type of modules, click [[Documentation/{{documentation/version}}/Developers/Modules|here]].

</li>

<li>If not already done, join [https://github.com/join Github] and [https://help.github.com/articles/set-up-git#set-up-git setup Git]</li>

<li>Save the source code of your extension by publishing it on Github

{{pre2|<nowiki>$ bin/slicerExtensionWizard --publish ~/Slicer-MyExtension/</nowiki>}}

</li>

<li>Implement your extension. <code>Hack, hack, hack :)</code>. Make sure to commit often using meaningful commit message.</li>

<li>[[Documentation/{{documentation/version}}/Developers/Tutorials/DocumentExtension#Extension_page|Create a documentation page for your extension]].</li>

<li>[[Documentation/{{documentation/version}}/Developers/Tutorials/ObtainExtensionServerApiKey|Create an account on the extension server and obtain an API Key]]. You will then use your midas login and api key to substitute <code><YOUR-MIDAS-LOGIN></code> and <code><YOUR-MIDAS-APIKEY></code> in the examples.</li>

<li>If not already done, go to [http://slicer.kitware.com/midas3/community/23 NA-MIC community] and click on <code>Join community</code></li>

<li>{{:Documentation/{{documentation/version}}/Developers/Tutorials/BuildTestPackageDistributeExtensions/ExperimentalFolderAccess}}</li>

<li>Assuming the source code of your extension is located in folder <code>MyExtension</code>, you could upload your extension doing:

<ol style="list-style-type:none; border-left:thick solid darkgreen; padding-left:1em;">
<li>To avoid typing the API email and key, you can set the environment variables <code>MIDAS_PACKAGE_EMAIL</code> and <code>MIDAS_PACKAGE_API_KEY</code>. More details [[Documentation/{{documentation/version}}/Developers/FAQ#How_to_cache_API_credentials_.3F|here]]</li>

<li>Check submission results on the dashboard: http://slicer.cdash.org/index.php?project=Slicer4#Extensions-Experimental
<ol style="list-style-type:none; border-left:thick solid red; padding-left:1em;">
<li>You should expect the test <code>MyCLITest</code> to fail with error of the form:
{{pre2|scroll|[nrrd] nrrdIoStateDataFileIterNext: couldn't open "~/MyExtension-build/MyCLI/Data/Baseline/CLIModuleTemplateTest.raw"}}
This is explained by the fact the <code>*.nhdr</code> file available on midas and downloaded locally still reference <code>CLIModuleTemplateTest.raw</code></li>
</ol>
</li>

<li>Check that the extension can be installed by starting the Slicer executable from <code>/path/to/Slicer-Superbuild/Slicer-build</code> and installing your extension as explained [[Documentation/{{documentation/version}}/SlicerApplication/ExtensionsManager|here]].</li>

<li>If you consider your extension is ready for distribution, contribute it to the ExtensionsIndex:

{{pre2|<nowiki>$ bin/slicerExtensionWizard --contribute ~/Slicer-MyExtension/</nowiki>}}

<ol style="list-style-type:none; border-left:thick solid darkgreen; padding-left:1em;">
<li>To contribute an extensions build against Slicer {{Documentation/currentversion}}. See [[Documentation/{{documentation/version}}/Developers/Tutorials/Contribute_Extension_Description_File_using_Extension_Wizard|here]].</li>
<li>To learn about extension description file format. See [[Documentation/{{documentation/version}}/Developers/Extensions/DescriptionFile|here]]</li>
