* <h3><a id="bundleprovider">Resource Bundles in Named Modules</a></h3>
* <h3><a id="resource-bundle-modules">Resource Bundles and Named Modules</a></h3>
*
* When resource bundles are deployed in named modules, the following
* module-specific requirements and restrictions are applied.
* Resource bundles can be deployed in modules in the following ways:
*
* <ul>
* <li>Code in a named module that calls {@link #getBundle(String, Locale)}
* will locate resource bundles in the caller's module (<em>caller module</em>).</li>
* <li>If resource bundles are deployed in named modules separate from
* the caller module, those resource bundles need to be loaded from service
* providers of {@link ResourceBundleProvider}. The caller module must declare
* "{@code uses}" and the service interface name is the concatenation of the
* package name of the base name, string "{@code .spi.}", the simple class
* name of the base name, and the string "{@code Provider}". The
* <em>bundle provider modules</em> containing resource bundles must
* declare "{@code provides}" with the service interface name and
* its implementation class name. For example, if the base name is
* "{@code com.example.app.MyResources}", the caller module must declare
* "{@code uses com.example.app.spi.MyResourcesProvider;}" and a module containing resource
* bundles must declare "{@code provides com.example.app.spi.MyResourcesProvider
* with com.example.app.internal.MyResourcesProviderImpl;}"
* where {@code com.example.app.internal.MyResourcesProviderImpl} is an
* implementation class of {@code com.example.app.spi.MyResourcesProvider}.</li>
* <li>If you want to use non-standard formats in named modules, such as XML,
* {@link ResourceBundleProvider} needs to be used.</li>
* <li>The {@code getBundle} method with a {@code ClassLoader} may not be able to
* find resource bundles using the given {@code ClassLoader} in named modules.
* The {@code getBundle} method with a {@code Module} can be used, instead.</li>
* <li>{@code ResourceBundle.Control} is <em>not</em> supported in named modules.
* If the {@code getBundle} method with a {@code ResourceBundle.Control} is called
* in a named module, the method will throw an {@code UnsupportedOperationException}.
* Any service providers of {@link ResourceBundleControlProvider} are ignored in
* named modules.
* </li>
* </ul>
* <h4>Resource bundles together with an application</h4>
*
* <h3><a id="RBP_support">ResourceBundleProvider Service Providers</a></h3>
* Resource bundles can be deployed together with an application in the same
* module. In that case, the resource bundles are loaded
* by code in the module by calling the {@link #getBundle(String)}
* or {@link #getBundle(String, Locale)} method.
*
* The {@code getBundle} factory methods load service providers of
* {@link ResourceBundleProvider}, if available, using {@link ServiceLoader}.
* The service type is designated by
* {@code <package name> + ".spi." + <simple name> + "Provider"}. For
* example, if the base name is "{@code com.example.app.MyResources}", the service
* type is {@code com.example.app.spi.MyResourcesProvider}.
* <p>
* In named modules, the loaded service providers for the given base name are
* used to load resource bundles. If no service provider is available, or if
* none of the service providers returns a resource bundle and the caller module
* doesn't have its own service provider, the {@code getBundle} factory method
* searches for resource bundles that are local in the caller module and that
* are visible to the class loader of the caller module. The resource bundle
* formats for local module searching are "java.class" and "java.properties".
* <h4><a id="service-providers">Resource bundles as service providers</a></h4>
*
* Resource bundles can be deployed in one or more <em>service provider modules</em>
* and they can be located using {@link ServiceLoader}.
* A {@linkplain ResourceBundleProvider service} interface or class must be
* defined. The caller module declares that it uses the service, the service
* provider modules declare that they provide implementations of the service.
* Refer to {@link ResourceBundleProvider} for developing resource bundle
* services and deploying resource bundle providers.
* The module obtaining the resource bundle can be a resource bundle
* provider itself; in which case this module only locates the resource bundle
* via service provider mechanism.
*
* <p>A {@linkplain ResourceBundleProvider resource bundle provider} can
* provide resource bundles in any format such XML which replaces the need
* of {@link Control ResourceBundle.Control}.
*
* <h4><a id="other-modules">Resource bundles in other modules and class path</a></h4>
*
* Resource bundles in a named module may be <em>encapsulated</em> so that
* it cannot be located by code in other modules. Resource bundles
* in unnamed modules and class path are open for any module to access.
* Resource bundle follows the resource encapsulation rules as specified
* in {@link Module#getResourceAsStream(String)}.
*
* <p>The {@code getBundle} factory methods with no {@code Control} parameter
* locate and load resource bundles from
* {@linkplain ResourceBundleProvider service providers}.
* It may continue the search as if calling {@link Module#getResourceAsStream(String)}
* to find the named resource from a given module and calling
* {@link ClassLoader#getResourceAsStream(String)}; refer to
* the specification of the {@code getBundle} method for details.
* Only non-encapsulated resource bundles of "{@code java.class}"
* or "{@code java.properties}" format are searched.
*
* <p>If the caller module is a
* <a href="{@docRoot}/java/util/spi/ResourceBundleProvider.html#obtain-resource-bundle">
* resource bundle provider</a>, it does not fall back to the
* class loader search.
*
* <h4>Resource bundles in automatic modules</h4>
*
* A common format of resource bundles is in {@linkplain PropertyResourceBundle
* .properties} file format. Typically {@code .properties} resource bundles
* are packaged in a JAR file. Resource bundle only JAR file can be readily
* deployed as an <a href="{@docRoot}/java/lang/module/ModuleFinder.html#automatic-modules">
* automatic module</a>. For example, if the JAR file contains the
* entry "{@code p/q/Foo_ja.properties}" and no {@code .class} entry,
* when resolved and defined as an automatic module, no package is derived
* for this module. This allows resource bundles in {@code .properties}
* format packaged in one or more JAR files that may contain entries
* in the same directory and can be resolved successfully as
* automatic modules.

* {@code ResourceBundleProvider} is a provider interface that is used for

* this interface are loaded with {@link java.util.ServiceLoader ServiceLoader}
* during a call to the
* {@link ResourceBundle#getBundle(String, Locale, ClassLoader)
* ResourceBundle.getBundle} method. The provider service type is determined by
* {@code <package name> + ".spi." + <simple name> + "Provider"}.
* {@code ResourceBundleProvider} is a service provider interface for
* resource bundles. It is used by
* {@link ResourceBundle#getBundle(String) ResourceBundle.getBundle}
* factory methods to locate and load the service providers that are deployed as
* modules via {@link java.util.ServiceLoader ServiceLoader}.
*
* <p>
* For example, if the base name is "com.example.app.MyResources",
* {@code com.example.app.spi.MyResourcesProvider} will be the provider service type:
* <pre>{@code
* <h3>Developing resource bundle services</h3>
*
* A service for a resource bundle of a given <em>{@code baseName}</em> must have
* a fully-qualified class name of the form:
* <blockquote>
* {@code <package of baseName> + ".spi." + <simple name of baseName> + "Provider"}
* </blockquote>
*
* The service type is in a {@code spi} subpackage as it may be packaged in
* a module separate from the resource bundle providers.
* For example, the service for a resource bundle named
* {@code com.example.app.MyResources} must be
* {@code com.example.app.spi.MyResourcesProvider}:
*
* <blockquote><pre>
* {@code package com.example.app.spi;
* public interface MyResourcesProvider extends ResourceBundleProvider {
* }
* }</pre>
* }</pre></blockquote>
*
* <p>
* This providers's {@link #getBundle(String, Locale) getBundle} method is called
* through the resource bundle loading process instead of {@link
* java.util.ResourceBundle.Control#newBundle(String, Locale, String, ClassLoader, boolean)
* ResourceBundle.Control.newBundle()}. Refer to {@link ResourceBundle} for
* details.
* <h3>Deploying resource bundle service providers</h3>
*
* @see <a href="../ResourceBundle.html#bundleprovider">
* Resource Bundles in Named Modules</a>
* @see <a href="../ResourceBundle.html#RBP_support">
* ResourceBundleProvider Service Providers</a>
* Resource bundles can be deployed in one or more service providers
* in modules. For example, a provider for a service
* named "{@code com.example.app.spi.MyResourcesProvider}"
* has the following implementation class:
*
* <blockquote><pre>
* {@code import com.example.app.spi.MyResourcesProvider;
* class MyResourcesProviderImpl extends AbstractResourceBundleProvider
* implements MyResourcesProvider
* {
* public MyResourcesProviderImpl() {
* super("java.properties");
* }
* // this provider maps the resource bundle to per-language package
* protected String toBundleName(String baseName, Locale locale) {
* return "p." + locale.getLanguage() + "." + baseName;
* }
*
* public ResourceBundle getBundle(String baseName, Locale locale) {
* // this module only provides bundles in French
* if (locale.equals(Locale.FRENCH)) {
* return super.getBundle(baseName, locale);
* }
* // otherwise return null
* return null;
* }
* }}</pre></blockquote>
*
* This example provides "{@code com.example.app.MyResources}"
* resource bundle of the French locale. Traditionally resource bundles of
* all locales are packaged in the same package as the resource bundle base name.
* When deploying resource bundles in more than one modules and two modules
* containing a package of the same name, <em>split package</em>,
* is not supported, resource bundles in each module can be packaged in
* a different package as shown in this example where this provider packages
* the resource bundles in per-language package, i.e. {@code com.example.app.fr}
* for French locale.
*
* <p> A provider can provide more than one services, each of which is a service
* for a resource bundle of a different base name.
*
* <p>{@link AbstractResourceBundleProvider}
* provides the basic implementation for {@code ResourceBundleProvider}
* and a subclass can override the {@link
* AbstractResourceBundleProvider#toBundleName(String, Locale) toBundleName}
* method to return a provider-specific location of the resource to be loaded,
* for example, per-language package.
* A provider can override {@link #getBundle ResourceBundleProvider.getBundle}
* method for example to only search the known supported locales or
* return resource bundles in other formats such as XML.
*
* <p>The module declaration of this provider module specifies the following
* directive:
* <pre>
* provides com.example.app.spi.MyResourcesProvider with com.example.impl.MyResourcesProviderImpl;
* </pre>
*
* <h3><a id="obtain-resource-bundle">Obtaining resource bundles from providers</a></h3>
*
* The module declaration of the <em>consumer module</em> that calls one of the
* {@code ResourceBundle.getBundle} factory methods to obtain a resource
* bundle from service providers must specify the following directive:
* <pre>
* uses com.example.app.spi.MyResourcesProvider;
* </pre>
*
* {@link ResourceBundle#getBundle(String, Locale)
* ResourceBundle.getBundle("com.example.app.MyResource", locale)}
* locates and loads the providers for {@code com.example.app.spi.MyResourcesProvider}
* service and then invokes {@link #getBundle(String, Locale)
* ResourceBundleProvider.getBundle("com.example.app.MyResource", locale)} to
* find the resource bundle of the given base name and locale.
* If the consumer module is a resource bundle service provider for
* {@code com.example.app.spi.MyResourcesProvider}, {@code ResourceBundle.getBundle}
* will locate resource bundles only from service providers.
* Otherwise, {@code ResourceBundle.getBundle} may continue the search of
* the resource bundle in other modules and class path per the specification
* of the {@code ResourceBundle.getBundle} method being called.

help.id.summary = a description of snippet IDs and how use them
help.id =\
Every snippet of code you enter has its own unique snippet ID. Even if you\n\
enter the same snippet again, it will have a new ID. For normal snippets the ID\n\
is an increasing number. Snippets which fail with an error have a snippet ID\n\
which begins with 'e'. Snippets in the startup have an ID which begins with 's'.\n\
\n\
A snippet ID is one way to refer to a snippet in a command. For example, this\n\
command drops the snippet with ID '14':\n\
\n\t\
/drop 14\n\
\n\
To see the ID of a snippet or snippets use the '/list' command. To see the ID\n\
of all snippets. including failed, startup, and overwritten snippets, use the\n\
'/list -all' command.\n\
\n\
You can also refer to a range of IDs by separating the beginning ID and ending\n\
ID with a hypen. For example, '1-4' is the same as '1 2 3 4'. All commands\n\
which refer to snippets will take a list of IDs, ID ranges, and snippet names\n\
as arguments. These commands are: /list, /edit, /drop, /save, /vars, /methods,\n\
/types, and /<id>. Some examples:\n\
\n\t\
/edit 7-23\n\
\n\t\
/save s1-s4 3-8 foo 12 myfile\n\
\n\t\
/9-12 33\n\
