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/

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 p...

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-specific syntax highlighter that should be able to match Markdown documents just as correctly as peg-markdown can, and that can easily be integrated into existing a...

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...

...ted 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 which I want to predict how often they would not fit together securely. The peg should be 1.8mm in diameter. But there are some variables which might affect if it is actually 1.8mm but I'd expect it to be normally distributed around 1.8mm with a known standard deviation. There are...

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]: 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 i...

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 synta...

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.

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...

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

...ion 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 functions of C++ so we can make a self-hosting langauge. Also, all of the action nodes in our example PEG parser are written in LLVM Assembly rather than only C++ (although they call functions from a C++ library) so I doubt it would work in Spirit2.1 without writing a syntax converter. The syntax converter may come in time but it's only optional. If you're really interested in a partially fin...

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 indicate what nautilus is doing. Any ideas? -mark -- Mark Belanger LTX Corporation
