在尝试将自定义 ParserPlugin 实现到我正在编写的库(Maven 项目,JDK 8)时,我遇到了 pegdown v1.4.2 的问题:
自定义插件:
public class CustomHeadersParserPlugin extends Parser implements BlockPluginParser {
public CustomHeadersParserPlugin() {super(HtmlMdProc.MDP_SETTINGS, HtmlMdProc.PROCESSING_TIME_LIMIT, DefaultParseRunnerProvider);
}
public CustomHeadersParserPlugin(Integer options, Long maxParsingTimeInMillis) {
super(options, maxParsingTimeInMillis, DefaultParseRunnerProvider);
}
public CustomHeadersParserPlugin(Integer options, Long maxParsingTimeInMillis, ParseRunnerProvider parseRunnerProvider) {
super(options, maxParsingTimeInMillis, parseRunnerProvider);
}
public CustomHeadersParserPlugin(Integer options, Long maxParsingTimeInMillis, ParseRunnerProvider parseRunnerProvider, PegDownPlugins plugins) {
super(options, maxParsingTimeInMillis, parseRunnerProvider, plugins);
}
//************* CUSTOM RULES ***************
...
挂钩用法:
public class HtmlMdProc {
public static final int MDP_SETTINGS = Extensions.HARDWRAPS | Extensions.AUTOLINKS | Extensions.TABLES | Extensions.FENCED_CODE_BLOCKS;
public static final long PROCESSING_TIME_LIMIT = 5000l;
...
public HtmlMdProc markdown() {
PegDownPlugins pdp = PegDownPlugins.builder().withPlugin(CustomHeadersParserPlugin.class).build();
PegDownProcessor mdp = new PegDownProcessor(MDP_SETTINGS, PROCESSING_TIME_LIMIT, pdp);
RootNode rn = mdp.parseMarkdown(text.toCharArray());
String result = new CustomMarkdownToHtmlSerializer().toHtml(rn);
if (result != null)
this.text = result;
else
logger.debug("Could not process markdown in {} seconds", PROCESSING_TIME_LIMIT / 1000);
return this;
}
测试:
@Test
public void testmarkdownWithoutCode() {
String before = "Simple new line\nTest\n\nTest\nVot";
String expected = "<p>Simple new line<br />Test</p><p>Test<br />Vot</p>".replaceAll("\r", "");
HtmlMdProc textProc = new HtmlMdProc(before);
String result = textProc.markdown().text();
assertEquals(expected, result);
}
测试例外:

- 我可以以某种方式绑定我的 CustomHeadersParserPlugin 以避免幽灵般的反射吗?
- 如果没有,请告诉我如何在 pom.xml 中设置 maven-bundle-plugin 以使其与 pegdown v 1.4.2 一起使用。
我在这里发现了讨论问题,但我太新手了,无法单独处理 Maven 插件和反射。
