Specified by:

getFileTypeExtension in class ThemeFilesProcessor

Returns:

file type extension

See Also:

ThemeFilesProcessor.getFileTypeExtension()

getExcludesConfigKey

protected String getExcludesConfigKey()

Description copied from class: ThemeFilesProcessor

Key for the property within the theme's properties file that can be configured to exlcude files of the type being processed

Specified by:

getExcludesConfigKey in class ThemeFilesProcessor

Returns:

property key for file type excludes

See Also:

ThemeFilesProcessor.getExcludesConfigKey()

getFileTypeDirectoryName

protected String getFileTypeDirectoryName()

Description copied from class: ThemeFilesProcessor

Name of the directory relative to the theme directory which contains files for the type

Specified by:

getFileTypeDirectoryName in class ThemeFilesProcessor

Returns:

directory name

See Also:

ThemeFilesProcessor.getFileTypeDirectoryName()

getFileListingConfigKey

protected String getFileListingConfigKey()

Description copied from class: ThemeFilesProcessor

Key for the property that will be written to the theme derived properties to list the included files for the file type

Specified by:

getFileListingConfigKey in class ThemeFilesProcessor

addAdditionalFiles

protected void addAdditionalFiles(List<File> themeFiles)

Adds JS files from the krad scripts directory to the theme file list

Specified by:

addAdditionalFiles in class ThemeFilesProcessor

Parameters:

themeFiles - list of additional files to included for the theme

See Also:

ThemeFilesProcessor#addAdditionalFiles(java.util.List)

sortThemeFiles

protected List<File> sortThemeFiles(List<File> pluginFiles,
                                    List<File> subDirFiles)

Sorts the list of JS files from the plugin and sub directories

The sorting algorithm is as follows:

1. Any files which match patterns configured by the property jsLoadFirst
2. JS files from plugin directories, first ordered by any files that match patterns configured with pluginJsLoadOrder, followed by all remaining plugin files
3. KRAD script files, in the order retrieved from retrieveKradScriptLoadOrder()
4. JS files from the theme subdirectory, first ordered by any files that match patterns configured with themeJsLoadOrder, then any remaining theme files
5. Files that match patterns configured by the property jsLoadLast. Note any files that match here will be excluded from any of the previous steps

Specified by:

sortThemeFiles in class ThemeFilesProcessor

Parameters:

pluginFiles - list of files that will be included and come from a plugin directory

subDirFiles - list of files that will be included and come from the theme subdirectory

Returns:

list of all files to include for the theme in the correct source order

retrieveKradScriptLoadOrder

protected List<String> retrieveKradScriptLoadOrder()
                                            throws IOException

Builds a list of KRAD script file names that indicates the order they should be loaded in

Populates a properties object from the file ThemeBuilderConstants.KRAD_SCRIPT_LOAD_PROPERTIES_FILE located in the KRAD script directory. Then pulls the value for the property org.kuali.rice.krad.theme.util.ThemeBuilderConstants#LOAD_ORDER_PROPERTY_KEY to get the configured file load order. The KRAD scripts directory is then listed to get the remaining files names which are added at the end of the file list

Returns:

list of KRAD file names (not including path or file extension)

Throws:

IOException

processMergeFileContents

protected String processMergeFileContents(String fileContents,
                                          File fileToMerge,
                                          File mergedFile)
                                   throws IOException

Checks the given file contents to determine if the last character is a semicolon, if not the contents are appended with a semicolon to prevent problems when other content is appended

Specified by:

processMergeFileContents in class ThemeFilesProcessor

Parameters:

fileContents - contents of the file that will be added

fileToMerge - file the contents were pulled from

mergedFile - file receiving the merged contents

Returns:

file contents to merge (possibly altered)

Throws:

IOException

minify

protected void minify(File mergedFile,
                      File minifiedFile)
               throws IOException

Minifies the JS contents from the given merged file into the minified file

Minification is performed using the Google Closure compiler, using com.google.javascript.jscomp.CompilationLevel#SIMPLE_OPTIMIZATIONS and EcmaScript5 language level

Specified by:

minify in class ThemeFilesProcessor

Parameters:

mergedFile - file containing the merged contents

minifiedFile - file created to receive the minified contents

Throws:

IOException
