[REBOL] protect-system caveat Re:(3)

Help defines a function in it called type-name, when it doesn't declare type-name to be local. Every time help runs it trounces the global word type-name. I've told Feedback. Another bug caught! :) Brian Hawley

I agree this is a help issue. I didn't notice before that if I did protect-system before any help, the help would still work, but sure enough, I did protect-system 1st thing, and help worked afterwards... --- [EMAIL PROTECTED] wrote: > Hi Grant > > This looks like a bug in 'help.

Hi Grant This looks like a bug in 'help. You should send it to feedback. The problem is caused by doing the >> help protect-system before doing protect-system. Done in the other order, everything works OK. snip Script: "User Preferences" (31-Oct-1999/18:54:30-8:00) >> protect-system >> help protect-system USAGE: PROTECT-SYSTEM DESCRIPTION: Protects all system functions and the system object from redefinition. PROTECT-SYSTEM is a function value. >> first: 5 ** Script Error: Word first is protected, cannot modify. ** Where: first: 5 >> BTW You can use 'source to look at the code for both 'help and 'protect-system. If you do >>source protect-system before doing 'protect-system, it does not cause this problem, which is one reason I think the bug is in 'help.

Setting protect-system seems to incapacitate 'help': >> help protect-system USAGE: PROTECT-SYSTEM DESCRIPTION: Protects all system functions and the system object from redefinition. PROTECT-SYSTEM is a function value. >> protect-system >> help protect-system ** Script Error: Word type-name is protected, cannot modify. ** Where: type-name: func [value] [ value: mold type? :value clear back tail value join either find "aeiou" first value ["an "] ["a "] value ] if >> Bummer, huh? __ Do You Yahoo!?

[REBOL] protect-system ?? Re:
Hi Timmy, Check your version number (type rebol/version), if it is pre 2.2.0.xx then you need to upgrade. Protect-system is a v2.2.0.xx command. Type upgrade to get the latest version.

[REBOL] protect-system ??
Hi I wrote protect-system in %user.r but I got an error saying it has no value. Here is what the guide said: If protect-system is set in the user .r file, then all words set within REBOL will be protected from modification because the user .r file is called by REBOL just after initializing itself. timmy
