I am working on this project, http://epsilonwiki.free.fr/lambdaway/, and would be happy to get your opinion back. Thanks a lot. Alain Marty

I suggest the home page explains what lambdaway is for in a nutshell. Digging around it looks like some kind of math markup for the web?

  You will find some elements of an answer to your question in http://epsilonwiki.free.fr/lambdaway/index.php?view=overview http://epsilonwiki.free.fr/lambdaway/index.php?view=overview where you will find links for a more precise introduction. In the previous workshop, http://epsilonwiki.free.fr/alphawiki_2/ http://epsilonwiki.free.fr/alphawiki_2/, you should find numerous examples of math calculus, web design and not only math markup, even if math markup can be easily built on the language. You can even play with lambdatalk in a console, http://epsilonwiki.free.fr/lambdaway/index.php?view=console http://epsilonwiki.free.fr/lambdaway/index.php?view=console, or install your own copy in your web account (simply running PHP) You are welcome in lambdaway

I had a look at your link, and this page in particular: http://epsilonwiki.free.fr/lambdaway/?view=lambdatalk%20one http://epsilonwiki.free.fr/lambdaway/?view=lambdatalk%20one If I understand well, it seems that you wrote some kind of lisp dialect with the following particularities (some of my observations might be wrong, so please correct them): - it's somehow executed in javascript, so when I load in page with lambdaway code in it, js executes the code and the output is displayed on the page - braces are replacing parenthesis - you allow unicode variables (like \Phi) - by default, an expression is a string, unless it's preceded by a colon (my first opinion is that it's not the best and it would be better to use the quotes for the strings like other languages do, but I can be wrong) I happen to be writing at the moment a blog post (it's not finished yet, but here is the beginning: http://eskatrem.github.io/Newton-Raphson http://eskatrem.github.io/Newton-Raphson ) that uses some mathematical symbols - it will also talk about lisp by the way. I guess it's something that could be - better? - done with lambdway?

  Yes for the three first points. Not at all for the last: as it can be seen in http://epsilonwiki.free.fr/lambdaway/?view=lambdatalk%20one http://epsilonwiki.free.fr/lambdaway/?view=lambdatalk%20one, lambdatalk's code is made of sequences of words skipped by the parser and forms (S-expressions) evaluated by the parser. Colons are used to prefix arguments in lambdas. You can see an example of Newton method in http://epsilonwiki.free.fr/alphawiki_2/?view=stock_maths_newton http://epsilonwiki.free.fr/alphawiki_2/?view=stock_maths_new.... Thanks for your interest :)

Please next time explain the thing being shown in the post itself. Welcome in the {lambda way} project, a workshop built as a thin overlay on top of any modern web browser, and devoted to writing, composing and coding on the web, where the markup, styling and scripting are unified in a single language, {lambda talk}.

  I will, thank you.

    This is brilliant by the way. Definitely show it to more people and get feedback, it is so outside of the norm that it will take time for the idea to spread.

You might want to edit and add a short description that people can read without clicking the link. Alternatively, "SHOW HN" is usually a direct link to your project.

  I can't find any button "edit" in order to follow your advice. Can you help me?

It's cool. Why using the braces rather than ()?
- martyalain 11y ago
  Because we are in a wiki, it's 95% standard text where () are frequently used (like that), not for bracketting S-expressions. I choose braces because they are rarely used in a standard text. So you can write things like {b Hello {u (brave new)} World} without any conflicts.

I tried clicking on this link while in India. Strangely enough, I'm getting this intriguing message- “Your requested URL has been blocked as per the directions received from Department of Telecommunications, Government of India. Please contact administrator for more information.”

  I had such a similar behaviour trying to access " http://epsilonwiki.free.fr/ http://epsilonwiki.free.fr/ " from a school where the administration had blackboxed websites belonging to "free.fr", I don't know why. Did you try an access elsewhere?
