_pegdown_ 1.2.0 has only one dependency: [parboiled for Java][parboiled], version 1.1.3. - -* The pegdown artifact is also available from maven central with group id **org.pegdown** and artifact-id **pegdown**. +Cons: +* pegdownScala is a beta version: interlaced HTML tags doesn't work correct, + PegDown is much better tested. +* No implementation for timeouts in pegdownScala. You may want to use Akka to handle long tasks. +* pegdownScala isn't optimized for performance. Usage ----- -Using _pegdown_ is very simple: Just create a new instance of a [PegDownProcessor] and call one of its -`markdownToHtml` methods to convert the given Markdown source to an HTML string. If you'd like to customize the -rendering of HTML links (Auto-Links, Explicit-Links, Mail-Links, Reference-Links and/or Wiki-Links), e.g. for adding -`rel="nofollow"` attributes based on some logic you can supply your own instance of a [LinkRenderer] with the call -to `markdownToHtml`. - -You can also use pegdown only for the actual parsing of the Markdown source and do the serialization to the -target format (e.g. XML) yourself. To do this just call the `parseMarkdown` method of the [PegDownProcessor] to obtain -the root node of the Astract Syntax Tree for the document. -With a custom [Visitor] implementation you can do whatever serialization you want. As an example you might want to -take a look at the [sources of the ToHtmlSerializer][ToHtmlSerializer]. - -Note that the first time you create a [PegDownProcessor] it can take up to a few hundred milliseconds to prepare the -underlying parboiled parser instance. However, once the first processor has been built all further instantiations will -be fast. Also, you can reuse an existing [PegDownProcessor] instance as often as you want, as long as you prevent -concurrent accesses, since neither the [PegDownProcessor] nor the underlying parser is thread-safe. - -See for the pegdown API documentation. - - -Parsing Timeouts ----------------- - -Since Markdown has no official grammar and contains a number of ambiguities the parsing of Markdown source, especially -with enabled language extensions, can be "hard" and result, in certain corner cases, in exponential parsing time. -In order to provide a somewhat predictable behavior *pegdown* therefore supports the specification of a parsing timeout, -which you can supply to the [PegDownProcessor] constructor. +Using _pegdownScala_ is very simple: Just call `ToHtmlSeralizer(markdownSource)`. -If the parser happens to run longer than the specified timeout period it terminates itself with an exception, which -causes the `markdownToHtml` method to return `null`. Your application should then deal with this case accordingly and, -for example, inform the user. +TODO: Add more documentation. -The default timeout, if not explicitly specified, is 2 seconds. - - -IDE Support ------------ - -The excellent [idea-markdown plugin] for IntelliJ IDEA, RubyMine, PhpStorm, WebStorm, PyCharm and appCode uses _pegdown_ -as its underlying parsing engine. The plugin gives you proper syntax-highlighting for markdown source and shows you -exactly, how _pegdown_ will parse your texts. +You can also use _pegdownScala_ from the command line to convert a Markdown file to HTML: +`pegdownScala ` Credits ------- +All the code is based on [PegDown] from Mathias Doenitz. I would never be able to build this +Scala port without your great work. + A large part of the underlying PEG grammar was developed by John MacFarlane and made available with his tool [peg-markdown](http://github.com/jgm/peg-markdown). - License ------- -_pegdown_ is licensed under [Apache License 2.0](http://www.apache.org/licenses/LICENSE-2.0). - - -Patch Policy ------------- +_pegdownScala_ is licensed under [Apache License 2.0](http://www.apache.org/licenses/LICENSE-2.0). -Feedback and contributions to the project, no matter what kind, are always very welcome. -However, patches can only be accepted from their original author. -Along with any patches, please state that the patch is your original work and that you license the work to the pegdown project under the project’s open source license.
