[英]How to make Eclipse formatter put a new line after arrays in a type annotation declartion?
[英]How to insert new line just after method and type annotations using Eclipse JDT code formatter?
我正在使用Eclipse JDT API格式化生成的Java源文件。 使用哪些选项,我可以强制格式化程序进行输出,如下所示:
@Annotation1
@Annotation2
@Annotation3
@Annotation4
public class TheClass {
private static final int PAGE_SIZE = 10;
@Annotation5
private Object o1;
@Annotation5
private Object o2;
@Annotation6
@Annotation7
public void doSomething(@Annotation8 @Annotation Object dto) {
// some works
}
}
据我所知, DefaultCodeFormatterOptions
具有insert_new_line_after_annotation
字段,该字段在所有注释(甚至方法参数注释)之后添加新行。 但是我想在类型方法或类型注释之后添加换行符
Edit:
这是格式化程序代码:
public String format(String code)
throws MalformedTreeException, BadLocationException {
Map options = new java.util.HashMap();
options.put(JavaCore.COMPILER_SOURCE, "1.5");
options.put(JavaCore.COMPILER_COMPLIANCE, "1.5");
options.put(JavaCore.COMPILER_CODEGEN_TARGET_PLATFORM, "1.5");
DefaultCodeFormatterOptions cfOptions =
DefaultCodeFormatterOptions.getDefaultSettings();
cfOptions.insert_new_line_after_annotation = false;
cfOptions.comment_insert_new_line_for_parameter = true;
cfOptions.blank_lines_before_method = 1;
cfOptions.number_of_empty_lines_to_preserve= 1;
cfOptions.tab_char = DefaultCodeFormatterOptions.SPACE;
CodeFormatter cf = new DefaultCodeFormatter(cfOptions, options);
TextEdit te = cf.format(CodeFormatter.K_UNKNOWN, code, 0,
code.length(), 0, null);
IDocument dc = new Document(code);
te.apply(dc);
return dc.get();
}
DefaultCodeFormatterOptions为注释的每个可能上下文在注释之后的换行处具有单独的字段
public boolean insert_new_line_after_annotation_on_type;
public boolean insert_new_line_after_annotation_on_field;
public boolean insert_new_line_after_annotation_on_method;
public boolean insert_new_line_after_annotation_on_package;
public boolean insert_new_line_after_annotation_on_parameter;
public boolean insert_new_line_after_annotation_on_local_variable;
所以我猜insert_new_line_after_annotation_on_type
是答案……我已经检查了它的行为与IDE本身(而非API)一样。
这是2014年2月提交的此修订添加的相对较新的内容,用于修复bug /功能425040 。 它在我前面的日食中可用4.4.0
