[REBOL] DOing a script from

From: SunandaDH:aol at: 31-Oct-2006 5:30

Hidden in the Library Recent Changes thread, Carl Read asked:

The Library now emits the HTML with a newline before the script header. This means that many scripts are DO-able from their Library webpage. Thanks to Carl and Gregg and Anton for raising and fixing the problem. **** Unfortunately, _many_ scripts are Do-able, but not the one in question. texture-lab.r contains greater-than and less-than signs. These are escaped to character entities in the HTML page, and that creates a syntax error. Gregg's solution still stands: use the version intended for execution rather than the one prettied up for display. Other alternatives include: -- download the script and run it locally. -- download the whole Library, and run the one script locally: Those first two suggestions work even when the library isn't available. -- Use the Library Data Services interface. Normally (see below for exception **) this best as it allows you to specify which version of a script you want to run -- the Library may have multiple versions of a script, and the most recent one may not be the one you want. do res: lds/send-server 'get-archive-version ["texture-lab.r/1"] do decompress res/data/script Normally, this would run Version 1 of texture-lab.r If there were other verisons, you could check them here: e-lab.r And that would work with most scripts in the Library. ** Sadly, texture-lab.r is an exception: it checks its own REBOL header. That means it is assuming it is running as a Do %name. So it fails as it can't find header/version. You could always save it to a temporary file and do it from there. **** Who said the X-Internet was easy!? Moral of the story: listen to Gregg. Sunanda.
