[opensuse-autoinstall] <match_type>regex</match_type> -- regex support?
I'm wondering *which* regex system is used here and what
the constraints on its use are.
Google: [ autoyast "
From this example, all i can infer is that a <match> element value is used as a non-anchored match string. ("match anywhere")
I have seen another example showing the use of the "^" begin-of-line anchor symbol e.g. "<match>^SUSE Linux Enterprise Server</match>". But what is the full-extent of what i can use here? for my needs right now, i'd like to use <product>PowerEdge [12]850</product> to match the Dell PE 1850 and PE 2850 systems. Will this work? (i imagine i may have to escape some patterns to fit XML specification, which i'm not very familiar with, but that's just a detail) thanks, --stephen -- Stephen Dowdy - Systems Administrator - NCAR/RAL 303.497.2869 - sdowdy@ucar.edu - http://www.ral.ucar.edu/~sdowdy/ -- To unsubscribe, e-mail: opensuse-autoinstall+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-autoinstall+help@opensuse.org

it's a simple bash "=~" if [[ "uwe gansert" =~ u.e\ g[abc]ns ]]; then echo jo; fi but while looking at the code a few minutes ago, I noticed a bug in it :( Currently only substring matching seems to work properly which is what I used for testing the code when I implemented it :-/ I have to test that but by looking at the code, it looks like a bug -- ciao, Uwe Gansert Uwe Gansert SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nürnberg) Business: http://www.suse.de/~ug -- To unsubscribe, e-mail: opensuse-autoinstall+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-autoinstall+help@opensuse.org

Ah, okay, great, that helps a lot. Indeed [..] character set matching works for "<product>\n<match>PowerEdge [12]850</match>" in my rules.xml file for this particular set of machines. I hope i'm not being pushy, but if you could update the AutoYast docs to reflect just what you said above, it'd be very helpful. (and possibly use a slightly more complex example than the "<match>ntel</match>" one you have.) ------------ 6.1.3. Match Types for rules .. regex can be used to match substrings like "ntel" will match "Intel","intel" and "intelligent". ------------

Well, My Dell 8th Gen Profile got pulled in by this rule just now:
<!-- Different Network Configuration for PE1850/PE2850s -->
<rule>
<product>
<match>PowerEdge [12]850</match>

Just to confirm (now that i'm digging through my y2logs (y2debug=1)... [YCP] AutoInstallRules.ycp:375 shell: ( [[ "$product" =~ "PowerEdge [12]850" ]] ) ... [liby2] SymbolEntry.cc(setValue):107 SymbolEntry::setValue (ismatch@0x1951030 = 'true') ... [liby2] SymbolEntry.cc(setValue):107 SymbolEntry::setValue (ruledef@0x1953500 = '$["continue":true, "profile":"ZORK-Dell8G.xml"]')
<!-- Different Network Configuration for PE1850/PE2850s --> <rule> <product> <match>PowerEdge [12]850</match>
regex </product> <result> <profile>ZORK-Dell8G.xml</profile> <continue config:type="boolean">true</continue> </result> </rule>

really? That's unexpected because the quoting of the right side of the expression is actually wrong in the code. It really works for you? Which SUSE Linux version?

okay, done.
