Has anyone seen any attempts to give Markdown a PEG (parsing expressions grammar) recognizable by some ruby PEG parser generator grammar like Treetop? http://treetop.rubyforge.org/

...it converts a 178K markdown file in 0.14 seconds (vs. 9.6 seconds for the latest Markdown.pl and 0.57 seconds for phpmarkdown). It passes all the tests in the Markdown 1.0.3 test suite, with one exception (an edge case where there is room for disagreement). It's on github at http://github.com/jgm/peg-markdown/tree/master. If you use git, you can clone the repository: git clone git://github.com/jgm/peg-markdown.git Otherwise, download a tarball: http://github.com/jgm/peg-markdown/tarball/master Once you're in the peg-markdown directory, you can compile the program by typi...

Markdowners: I've released version 0.4.1 of peg-markdown, a C implementation of markdown. peg-markdown uses Ian Piumarta's peg/leg parser generator to generate a parser from a parsing expression grammar (PEG). You can inspect the grammar for markdown at http://github.com/jgm/peg-markdown/tree/HEAD/markdown_parser.leg peg-markdown now provides both a C library and a standalone 'markdown' program. The memory leaks in previous versions have been plugged, and parsing accuracy has been improved considerably. peg-markdown is very fast (on my machine, it parses a 1...

...rammar] for markdown. I used Haskell and John Meacham's Frisby PEG parsing library, but it should not be too hard to port the grammar to PEG libraries in other languages. [parsing expression grammar]: http://en.wikipedia.org/wiki/Parsing_expression_grammar The code is at <http://github.com/jgm/markdown-peg/tree/master>. All that is required to compile it is the GHC haskell compiler. The grammar itself begins at line 68 of Markdown.hs: <http://github.com/jgm/markdown-peg/tree/master/Markdown.hs#L68>. This implementation is not particularly fast, though it is still faster than Ma...

I don't believe this question has been discussed before on this list: Should whitespace be allowed between the bracketed and parenthesized parts of an inline link? For example, [foo] (/url) The markdown syntax documentation says explicitly that a space is allowed between the two parts of a *reference-style* link: > Reference-style links use a second set of square brackets, inside

Full_Name: James MacKinnon Version: Version 1.0.0 OS: Debian 2.1 Submission from: (NULL) (24.141.113.138) I am a novice at R, so I am not totally sure that this is a bug, but I think it must be. When I type help.start() or ?help, Netscape starts up, as it should, but it displays my normal home page, not any help for R. The relevant documents exist in /usr/lib/R/doc/html, but Netscape does not

Markersdown: I was fooling around with lua and decided to write a markdown parser using the terrific lpeg library. Here's the result: http://github.com/jgm/lunamark/tree/master There are already two markdown libraries for lua, one a native lua implementation based on global substitutions, the other a binding to discount. What makes lunamark different is that it is based on a PEG grammar (adapted from my peg-markdown). This can be found in the file...

...tle blocks, and a very flexible metadata format. These can be turned on and off individually. Lunamark is designed with hackability in mind; I see it as a good testbed for exploring markdown syntax ideas. It includes an extensive test suite. For more information, see lunamark's website: http://jgm.github.com/lunamark. John

It seems that Markdown 1.0.1 strips off trailing spaces at the end of code blocks. Is this really what it's supposed to do? There might be reasons to include trailing spaces in code displayed on a web page -- for example, in demonstrating how to do a hard line break in markdown. Even if the trailing spaces aren't visible, they can be cut and pasted. Besides, Markdown 1.0.1 preserves

...andoc is a command-line program. If you don't like using the terminal, though, there are ways of integrating pandoc with a text editor. You can find an Emacs mode (which gives you menu options for converting to various formats), a vim syntax file, and a TextMate bundle here: https://github.com/jgm/pandoc/wiki/Pandoc-Extras. If you use OS X, David Sanson has created some droplets and services that make it easy to use pandoc without going to the terminal (https://github.com/dsanson/Pandoc-Droplets-and-Services). There is also gitit, a git-based wiki (http://gitit.net) that uses pandoc and can...

The "markdown" package does some of what R would need to make use of Sundown, but not all: we really do need an R object representation of the parse tree, fo...

Thanks Brian. Indeed, the vignette is in markdown form. When I updated my system to R 3.1.3 I ran update.packages() and this seems to have upset things (including R-studio processing of markdown files). I tried removing rmarkdown and reverting to an older version so that my sessionInfo() is Loading required package: rmarkdown > sessionInfo() R version 3.1.3 (2015-03-09) Platform:

I'm curious how people think the following *should* be interpreted: - one 2. two http://babelmark.bobtfish.net/?markdown=-++one%0D%0A2.+two%0D%0A%0D%0A As you can see, implementations split into three groups here: (a) treat as an unordered list Markdown.pl, Python markdown, MultiMarkdown, BlueCloth, MarkdownJ, Showdown (b) treat as an unordered list with an ordered
