Treetop or like grammar for Markdown (in Ruby)
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/

peg-markdown (C) and rpeg-markdown (ruby gem)
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

PEG Markdown Highlight
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

markdown implementation in C using PEG 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

...a round hole. Whee, I just _know_ I'm going to be positively skewered (and maybe even plonked!) for this.... but, hey, it's Friday, and this post is meant to be a bit funny.? So lighten up, and enjoy a short read. obHumor: I actually have a piece of furniture (a small table) with square pegs in round holes.? The spaces between the sides of the square peg and the round hole are filled with a color-contrasting glue, and the result is rather pretty.? :-)? I intentionally picked this furniture specifically because of the square pegs in the round holes..... obHistory: Cobblers making bo...

?OT: Probabilistic Simulation
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

markdown PEG (parsing expression grammar)
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]:

[LLVMdev] PEG parsers? (was Re: Regular Expressions)
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 syntax based parsers and LLVM Assembly code for all of the code-generation stages so that we can debug the code and the parser all in one go. It's part of the Mattathias BASIC pr...

Differing Variable Length Inconsistencies in Random Effects/Regression Models
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) >

Samba process pegging CPU
Greetings, I'm currently experiencing an issue with two of my three Samba servers where one Samba process is pegging the CPU usage and eating up a lot of virtual and resident memory. While this is happening I get a "ERROR(runtime): DsReplicaGetInfo of type 0 failed - (-1073610723, 'NT_STATUS_RPC_PROTOCOL_ERROR')" error when I try to run the samba-tool drs showrepl command.

lunamark - markdown in lua using a PEG grammar
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

kjournald pegging cpu
kernel version 2.6.10-1.771_FC2smp We have had quite a few instances of kjournald pegging cpu and thereby effectively knocking out the system's i/o. What can we do to provide more information so that the cause can be identified and fixed? Thanks Christopher

[LLVMdev] accessing a bitcode library exported from C++ using the JIT
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

Row names and matrixs
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)<-

Splitting massive output into multiple text files
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

nautilus pegging the cpu
I have a user that is running centos on many machines. At each machine, the users is logged into a common account that is located elsewhere on the network. Meaning that everyone is logged on as user_x and accessing the home directory via NFS. All users are running gnome. On some of the machines, the nautilus process is pegging the cpu. At this time, I have no strace or other info to
