[Chicken-users] Unit ports documentation needs an example or two for non-gods
(port-map FN THUNK) where does the port go? I was sort of hoping for something like this to work: csi (define inp (open-input-file ~/.bashrc)) csi (define a (port-map inp read-line)) csi (close-input-file inp) but it took guessing to figure out the intended usage. How about some trivial examples in the docs? By trial and error I figured this out: (define a (with-input-from-file ~/.bashrc (lambda ()(port-map (lambda (x) x) read-line That is ugly. I just want to get a file into a list: E.g. in Ruby: foo=`cat ~/.bashrc` port-fold doesn't improve it: (define b (with-input-from-file ~/.bashrc (lambda ()(reverse (port-fold cons '() read-line) Is there an egg or unit for down-n-dirty, get-the-job-done-yesterday, screw the right thing programming? (use ducttape) (define a (file-list ~/.bashrc)) Such a unit or egg deserves mention on the front page. I dug though the docs and never did find an easy way to do what I want. ___ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users

I'm personally not aware of any eggs that specifically match your request. But there are these eggs, which I tend to use more often than others: Misc Macros http://wiki.call-cc.org/eggref/4/miscmacros More Macros http://wiki.call-cc.org/eggref/4/moremacros lookup-table http://wiki.call-cc.org/eggref/4/lookup-table Sequences http://wiki.call-cc.org/eggref/4/sequences SRFI-99 http://wiki.call-cc.org/eggref/4/srfi-99 Less general, but still often useful: SRFI-45 http://wiki.call-cc.org/eggref/4/srfi-45 lazy-seq http://wiki.call-cc.org/eggref/4/lazy-seq -Dan On Wed, May 23, 2012 at 6:35 AM, Matt Welland estifo...@gmail.com wrote: (port-map FN THUNK) where does the port go?

You can do that with (call-with-input-file PATH read-lines) or (read-lines my-file.txt) The latter comes from this page http://wiki.call-cc.org/chicken-for-python-programmers which documents a few down-and-dirty idioms.

Re: [Chicken-users] segv with stty egg
Hi Aaron! * Aaron Patterson tenderl...@ruby-lang.org [120523 04:45]: I am trying to read from a tty with Chicken. I've been messing around with the stty egg, and it seems to be segving on me. Here is the script I'm using: https://gist.github.com/2772939 I know I'm not using the stty egg correctly, but I don't think it should be segving in this case. Thanks! Hm, indeed a crash is not nice! Can you try whether it also crashes for you with the stty's trunk version? Thanks!

I feel new in the Chicken Scheme community, so I'm not sure where to locate this type of information. :-) Sorry, maybe the docs are a bit scattered, but since we are used to it, we end up not noticing some omissions or bad organization (we actually know the organization is bad, but fixing it, you know...). Here's a quick summary: * The CHICKEN core (compiler, interpreter, runtime system, profiler, eggs manager) code is maintained in a git repository (see http://code.call-cc.org for info about how to get it). * Eggs can be hosted by the subversion repository at call-cc.org or, more recently, on remote VCSs (see http://wiki.call-cc.org/releasing-your-egg). When eggs are not hosted by the svn repository at call-cc.org, you probably can find the egg repository location in the egg documentation (http://wiki.call-cc.org/egg/the-egg). If the egg author has not provided that information in the egg documentation (he/she should), you can find it out by looking at the egg-locations file (https://anonym...@code.call-cc.org/svn/chicken-eggs/release/4/egg-locations -- empty password) * You can also get eggs source code with chicken-install: $ chicken-install -r the-egg If you want some specific version: $ chicken-install -r the-egg:the-version If you want to get the tests too: $ chicken-install -r -test the-egg tl;dr: http://code.call-cc.org/ provides guidelines about how to obtain code hosted on call-cc.org. For eggs hosted remotely, check the egg documentation or the egg-locations file. You can quickly and VCS-agnostically get eggs source code with chicken-install. Eventually, I'd like to extend the egg to support cfsetispeed and cfsetospeed so that I can read from a tty. Nice. Thanks for your interest in contributing. Best wishes.
