A page for discussing Twig
Stu 2008-11-16 Numbers and checksums on this page current as of their writing.
Preemptive Q&A:
Q: Isn't it dangerous to run code from strange places?<<br>> A: The danger can be averted by checking the code then calculating a checksum and verifying the code against the checksum before running it. Hence, Twig. Q: Ok, there's this page of 'twigs'. What if someone alters the code then alters the checksum in that big bundle of twigs? A: There is a checksum against the entire block (or 'bundle', if you prefer). Q: What if someone alters that as well? A: I keep the twig of that block on my site as well; you can check against that. Q: Can I trust you? A: I'd like to think so. Q: I don't know ... A: You can save the twig(s)/check the code yourself.
Get Twig from Twig or my site. If you're too lazy to copy & paste then wget and a bit of awk can do it. General use instructions on the Twig page.
How to use the twigs on the Twigs page (if you're not using TkTwig).
These examples assume that Twig is installed in your path as 'twig'.
# run #111
$ twig 21912 4 | awk 'NR==111 {print}' | twig -c - | wish &
# verify twigs, then run #111
$ twig 21912 2 | twig -c - | awk 'NR==111 {print}' | twig -c - | wish &Get TkTwig from TkTwig or my site. Use it or Twig to get the twigs on the Twigs page or get them some other way. Find some new ones and share!
If you're really lazy, this will pull both TkTwig and the Tcler's Wiki twigs, combine and run.
(twig 21912 2 | twig -c - | awk 'NR==310 {print}' | twig -c -; echo 'set ::cow {'; twig 21912 2 | twig -c -; echo '};tktwig::loadBundle +::cow') | wish &Or this:
(twig 21912 2 | twig -c - | awk 'NR==310 {print}' | twig -c -; twig 21912 2 | twig -c -) | wish -b - &Interesting results can be achieved by combining pages.
This combines the Starfield and Spirograph pages. I've found that Starfield can be mixed with many others.

The above could also be done as follows, without any checking. Be careful!

Twig for Canvas presentation graphics (3312)
To do this I had to revert my previous changes to the 3312 page so the twig for this on the Twigs page will no longer work. This is all a work in progress; the Twigs page should get updated often enough.

I forgot about echo:// when I originally wrote this bit; it would be easiest to do with echo://.
I'd like to run A little fortune teller but I don't run the same OS as the original author so my fortunes file is in a different location than specified in the code. To make this work, I've split the original code block into two blocks: the first sets the name of the fortunes file and the second is the rest of the code. All I need now is a twigged line of code setting the name of the fortunes file.
Fortunes file on OpenBSD
# fortunes file on OpenBSD set filename /usr/share/games/fortune/fortunes
These are done a bit differently, a little more manual effort is involved.
The twigs could all be put into one file and that file twigged for extra ease and security.
First, gather some info
# standard fortunes file $ twig -g 9425 1 9425 1 D990C81E4F6FD15F00BA3553A5CF8575 # fortunes prog $ twig -g 9425 2 9425 2 2149D71A722942130CB7E7EE1529FBB4 # openbsd fortunes file $ twig -g 21913 20 21913 20 3A324AB59E40E456134313F8263993BC
Run A little fortune teller (9425) (standard)
$ (twig -s D990C81E4F6FD15F00BA3553A5CF8575 9425 1; twig -s 2149D71A722942130CB7E7EE1529FBB4 9425 2) | wish &
Run A little fortune teller (9425) (OpenBSD)
$ echo "21913 20 3A324AB59E40E456134313F8263993BC\n9425 2 2149D71A722942130CB7E7EE1529FBB4" | twig -c - | wish &
It can also be done more directly. There are many ways to achieve the same result.
$ (echo 'set filename /usr/share/games/fortune/fortunes'; twig -s 2149D71A722942130CB7E7EE1529FBB4 9425 2) | wish &
Or skip making a twig and simply use echo://.
$ echo '{echo://set filename /usr/share/games/fortune/fortunes} 1 DO-NOT-VERIFY-SUM\n9425 2 2149D71A722942130CB7E7EE1529FBB4' | twig -c - | wish &It's big, ugly, and obvious - for a good reason. Having something like an empty string to signify that you wish to ignore the checksum would be overly prone to slipups. Therefore, if you wish to ignore the sum you have to spell out nice and big that that's want you want to do, no mistake. Running verified and checksummed code is the way of Twig.
I was quite excited when I saw Flowers but a little let down that I'd have to download the images before using the program. Here's a bit of code that overrides the image command so that the files are retrieved using the http package. It cheats by knowing that the first three calls will be to load the files. After loading the last image it destroys itself and its associated globals and puts back the original image command.
# Flower picker
set _c 3; set _u http://pagesperso-orange.fr/maurice.ulis/tcl/
rename image _i;
proc image {create photo name -file file} {
global _c _u
package require http
set tok [http::geturl $_u$file]
_i create photo $name -data [http::data $tok]
http::reset $tok
if {[incr _c -1] == 0} { unset _c _u; rename image {}; rename _i image }
}Put it together:
# Flower picker (21913:26) and Flowers (9888:2)
21913 26 6930BEA578BC001A56046F4C12E94F1D {} {Flower picker}
9888 2 925B0AD0046444A6C7A9ADF37F46F239 {} FlowersCheck:
$ twig 21913 27
# Flower picker (21913:26) and Flowers (9888:2)
21913 26 6930BEA578BC001A56046F4C12E94F1D {} {Flower picker}
9888 2 925B0AD0046444A6C7A9ADF37F46F239 {} Flowers
