Method Details

createAddClassNameExprUsingLumoVariables

public static com.github.javaparser.ast.expr.Expression createAddClassNameExprUsingLumoVariables(com.github.javaparser.ast.expr.Expression owner,
 Object value,
 com.github.javaparser.ast.CompilationUnit cu)

Creates addClassNames call for the given owner using value. When value is plain string, it searches lumo utility replacements and replaces plain string class names with LumoUtility classes as possible.

If there is no change, it returns null "gap-m p-m" -> LumoUtility.Gap.MEDIUM, LumoUtility.Padding.MEDIUM
"foo gap-m" -> "foo", LumoUtility.Gap.MEDIUM

Parameters:

owner - owner of the adding class related call.

value - Class name arg value. If it is not string, returns null.

cu - Complication unit to add lumo utility import if required

Returns:

methodCallExpr that is owner scoped addClassNames. e.g.
fooBtn.addClassNames(LumoUtility.Position.ABSOLUTE);

addClassNameWithArgs

public static boolean addClassNameWithArgs(ComponentInfo component,
 List<com.github.javaparser.ast.expr.Expression> arguments)

Creates addClassNames(...) statement with given arguments if there is none. Adds arguments to existing one.

Parameters:

component - the component to add class name

arguments - class name arguments. Most likely StringLiteral or FieldAccessExpr generated for LumoUtility.

Returns:

true if added successfully, false otherwise.

removeClassNameArgs

public static void removeClassNameArgs(ComponentInfo component,
 String... lumoUtilityClassNames)

Searches addClassName, addClassNames, setClassName methods for given component and then remove given lumo utility class names. e.g. if self-start is given for removal, LumoUtility.AlignSelf.START and "self-start" are removed from args.

Parameters:

component - the component to remove class names

lumoUtilityClassNames - Utility class names such as "align-items", "gap-m"

addLumoUtilityImport

public static void addLumoUtilityImport(com.github.javaparser.ast.CompilationUnit compilationUnit)

getLumoMethodArgExpressions

public static List<com.github.javaparser.ast.expr.Expression> getLumoMethodArgExpressions(String lumoInnerClassName,
 List<String> classNames)

Converts given class names to LumoUtility field access expressions. e.g. items-center becomes AlignItems.CENTER

Parameters:

lumoInnerClassName - Inner class name of LumoUtility class. e.g. AlignSelf, AlignItems etc...

classNames - html class names

Returns:

list of expressions.

getLumoMethodArgExpressions

public static List<com.github.javaparser.ast.expr.Expression> getLumoMethodArgExpressions(List<String> lumoInnerClassNames,
 List<String> classNames)

Converts given class names of given lumo inner class name lists and return all.

Parameters:

lumoInnerClassNames - List of lumo inner class names e.g. Gap, Gap.Row, Gap.Column

classNames - class names to look up in given lumo classes

Returns:

List of expression to add to a method as arguments

addLumoUtilityStylesheetIfNotExists

public static void addLumoUtilityStylesheetIfNotExists(com.vaadin.flow.server.VaadinContext vaadinContext)
                                                throws IOException

Check if @StyleSheet("styles.css") exists on main app class -> yes, put @import "lumo/utility.css" at the top Check if @StyleSheet(Lumo.STYLESHEET) exists on main app -> yes, put @StyleSheet(Lumo.UTILITY_STYLESHEET) below it Otherwise Lumo is loaded in custom way, so just create styles.css add it to main app class using @StyleSheet("styles.css") and add @import "lumo/utility.css" inside. Same as ThemeEditor is doing.

Parameters:

VaadinContext - Context to find the main class of Spring Applications

Throws:

IOException - is thrown when file operation fails
