16. Code Style Setting

代码样式设置允许定义格式选项。代码样式设置提供程序将创建设置的实例，还可以创建选项页面以进行编辑。在此示例中，我们将创建一个页面，该页面使用由语言代码样式设置提供程序自定义的默认语言代码样式设置。

16.1。

定义代码样式设置

package com.simpleplugin;

import com.intellij.psi.codeStyle.*;

public class SimpleCodeStyleSettings extends CustomCodeStyleSettings {
  public SimpleCodeStyleSettings(CodeStyleSettings settings) {
    super("SimpleCodeStyleSettings", settings);
  }
}

16.2。

定义代码样式设置提供程序

package com.simpleplugin;

import com.intellij.application.options.*;
import com.intellij.openapi.options.Configurable;
import com.intellij.psi.codeStyle.*;
import org.jetbrains.annotations.*;

public class SimpleCodeStyleSettingsProvider extends CodeStyleSettingsProvider {
  @Override
  public CustomCodeStyleSettings createCustomSettings(CodeStyleSettings settings) {
    return new SimpleCodeStyleSettings(settings);
  }

  @Nullable
  @Override
  public String getConfigurableDisplayName() {
    return "Simple";
  }

  
  @NotNull
  public CodeStyleConfigurable createConfigurable(@NotNull CodeStyleSettings settings, @NotNull CodeStyleSettings modelSettings) {
    return new CodeStyleAbstractConfigurable(settings, modelSettings, this.getConfigurableDisplayName()) {
      @Override
      protected CodeStyleAbstractPanel createPanel(CodeStyleSettings settings) {
        return new SimpleCodeStyleMainPanel(getCurrentSettings(), settings);
      }
    };
  }
  
  private static class SimpleCodeStyleMainPanel extends TabbedLanguageCodeStylePanel {
    public SimpleCodeStyleMainPanel(CodeStyleSettings currentSettings, CodeStyleSettings settings) {
      super(SimpleLanguage.INSTANCE, currentSettings, settings);
    }
  }
}

16.4。

定义语言代码样式设置提供者

package com.simpleplugin;

import com.intellij.lang.Language;
import com.intellij.psi.codeStyle.*;
import org.jetbrains.annotations.NotNull;

public class SimpleLanguageCodeStyleSettingsProvider extends LanguageCodeStyleSettingsProvider {
  @NotNull
  @Override
  public Language getLanguage() {
    return SimpleLanguage.INSTANCE;
  }

  @Override
  public void customizeSettings(@NotNull CodeStyleSettingsCustomizable consumer, @NotNull SettingsType settingsType) {
    if (settingsType == SettingsType.SPACING_SETTINGS) {
      consumer.showStandardOptions("SPACE_AROUND_ASSIGNMENT_OPERATORS");
      consumer.renameStandardOption("SPACE_AROUND_ASSIGNMENT_OPERATORS", "Separator");
    } else if (settingsType == SettingsType.BLANK_LINES_SETTINGS) {
      consumer.showStandardOptions("KEEP_BLANK_LINES_IN_CODE");
    }
  }

  @Override
  public String getCodeSample(@NotNull SettingsType settingsType) {
    return "# You are reading the \".properties\" entry.\n" +
           "! The exclamation mark can also mark text as comments.\n" +
           "website = http://en.wikipedia.org/\n" +
           "\n" +
           "\n" +
           "\n" +
           "language = English\n" +
           "# The backslash below tells the application to continue reading\n" +
           "# the value onto the next line.\n" +
           "message = Welcome to \\\n" +
           "          Wikipedia!\n" +
           "# Add spaces to the key\n" +
           "key\\ with\\ spaces = This is the value that could be looked up with the key \"key with spaces\".\n" +
           "# Unicode\n" +
           "tab : \\u0009";
  }
}
