Dear fellow Markdown enthusiasts, As you all might know, Markdown is a highly context sensitive language that the (often regex-based) syntax highlighting mechanisms in existing editors struggle to keep up with. I have taken John MacFarlane's excellent peg-markdown compiler and modified its parser to function as an interpreter for syntax highlighting purposes. The end result is a

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/

There's been a lot of discussion on this list about creating a formal grammar for markdown. I had a go at writing a [parsing expression grammar] 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]:

I've just uploaded an implementation of markdown in C. It defines the syntax using a PEG grammar, so it should be easy to extend and modify. Right now it can produce output in either HTML or LaTeX, but it would be simple to add other output formats. It's very fast: on my machine, it converts a 178K markdown file in 0.14 seconds (vs. 9.6 seconds for the latest Markdown.pl and 0.57 seconds

How can we improve URL detection in Markdown? I posted a question on Stack Overflow and happened to click a URL in my post. To my surprise, it wasn't functional, and it took three different, nonintuitive manipulations before I achieved a functional URL. Stack Overflow says "not my problem", so I'm deferring to Markdown itself. Here's a

Hi all I've started writing an OS X Markdown "editor"[1] that semi-formats your markdown document as you write it. I just wanted to put something together, so went with a regexp-based setup for parsing -- Not ideal! I'd really like to use an existing parser, but I need to get access to the parse-tree *with* character offets, rather than just html output, as I'm adding

Hi, because of the great editor "Writer" from Information Architects I've learned about Markdown and I love it. But it's very confusing, that there are so many standards with different features: classical Markdown, Markdown Extra, MultiMarkdown. I think for most users and the spreading of Markdown it would be nice, to have only one syntax. And this universal syntax should have

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

Sorry this may well be defined as Off Topic. I apologize in advance. I am interested in performing what I think would be a probabilistic sensitivity simulation. I've done some crude ones before in excel but I'm wondering if R can help me do it more effectively? I have a set of theoretical variables for simplicity lets use (what I think) is an easier example: I have a peg and a hole

Dear All, I am quite new to R and am having a problem trying to run a linear model with random effects/ a regression- with particular regard to my variable lengths being different and the models refusing to compute any further. The codes I have been using are as follows: vc<-read.table("P:\\R\\Testvcomp10.txt",header=T) >> attach(vc) > > family<-factor(family) >

Markdowners, just a short heads-up to a newly released Markdown implementation: "pegdown" (http://github.com/sirthias/pegdown) implements a Java Markdown-to-HTML processor based on a PEG parser with the grammar being based on John MacFarlanes C implementation "peg-markdown". pegdown uses "parboiled" (http://www.parboiled.org) for the actual parsing work and, as

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

Hello OvermindDL1, We are implementing an extensible language. That's one where you can add commands and constructs to the language without having to recompile the parser. We want compilation of the parser in order to "freeze" it but only as an option. One goal is to eventually get the macro functions of our language to the point where they are equivalent to the template

Hi all - I am NEW to R and NEW to any type of programming. I am making heatmaps using the heatmap.2 function within gplots package. At present, when the heatmap is plotted it uses the row identifiers as 1,2,3,4...etc. However, I much rather use my own labels. I was told my another well-versed R programmer to use the follow script: x<-as.matrix(test1[,-1]) ## skip column 1 rownames(x)<-

Dear List, I thought it would be much easier to put a second query into a second mail. I need to print 426*10000 blocks of variance components data, where 426 is the number of columns of data that have 10000 permutations of variance generated for each of them. I have tried printing out a smaller number of permutations for a smaller number of markers and that has worked. However, since a

Hello everybody, I don't quite understand how the proposed regex library works but I know that PEG parser generators use a super-set of regex functionality to define their parsers. There's also a nice one on Google code called YARDparser that uses templates based on PEGs to generate efficient recursive-decent parsers. Furthermore, my partner and I am working on an interpreter for PEG

Hi, I'm writing a Markdown Parser in Scheme by porting bits of Markdown.pl. As you're probably aware, the Perl version massages the file into the final output with a number of regexes. In my version I'm trying to use the regexes to detect the starts and ends of the features and then take specific action to emit the final representation. I'm doing it this way because I want to

Dear R users, I am trying to fit an lmer model with only random effects which is giving me the following error: Error : length(f1) == length(f2) is not TRUE In addition: Warning messages: 1: In P1L55:family : numerical expression has 390 elements: only the first used 2: In P1L55:family : numerical expression has 390 elements: only the first used I am trying to extract variance components

Dear R-Users, Have a question about reading in some data and manipulating dates. I have a data set in excel which looks like this: Date PEG ETN HSP PTC 13/10/2004 41.92 64.75 29.86 9.27 14/10/2004 41.93 61.79 29.98 9.14 15/10/2004 41.69 62.7 30.09 9.04 18/10/2004
