or some snmp tool, if your device suports it ...

Hi, 
Pekr,

I appreciate that the concept for parsing is different to the use 
of regular expressions, but there are some things that do map from 
one to the other & I wondered if any table of those things existed. 
 As a noob sometimes the hardest questions to get answered are the 
ones where the answer is that there is no concept such as that sought 
by the noob. e.g. how do you grow strawberries in the sea?
 

The first match must be at the begining of the line. If it was the 
first line in the set then it would not be after a new line, but 
other cases it would be.


I will use parse/all from now, I like the extra control you describe.


here a few lines of a test input, the script I am hoping to develop 
is to parse the config files from Cisco devices in order to extract 
the layer 2 & 3 information together with the interface names & descriptions.

lines: {interface FastEthernet0
 description The connection to the printer
!
interface FastEthernet1
!
interface Vlan1
 description User vlan (only 1 vlan allowed)
 no ip address
!
interface Dialer0
 description Outside
 ip address negotiated
!
interface BVI1
 description Inside
 ip address 192.168.0.1 255.255.255.0
!
ip sla 3
 icmp-echo 217.0.0.1 source-interface Dialer0

ip route 0.0.0.0 0.0.0.0 Dialer0

interface ATM0.1 point-to-point
 no ip redirects
 no snmp trap link-status
 pvc 0/38
  pppoe-client dial-pool-number 1
 !
}


; sqlab, your change to use "thru newline" does what I wanted in 
this case which is good.

; my next step is to try & understand the "or" construct properly 
as the code below dosn't quite cut it.

wanted: copy []
interface: ["interface" [to #"^/" | to "point-to-point"]]

parse lines [any [[copy temp interface (insert tail wanted temp)] 
| thru newline ]]
foreach line  wanted [print line]

; thanks very much for your help, /\/\

guru question;  Will a utype! definition be allowed to wrap builtins? 
 SNMP MIBs require a fairly heavy weight tuple!  But will a short 
MIB conflict with internal scans of tuple! or do utype! scans take 
some form of precedent?  I've become curious, yet remain dumb enough 
to not know.

another question, although not web related, but log related - did 
anyone do snmp parser, mrtg kind of graph display?

Yes. We have one for our own use. But not snmp implementatin. However 
the french have something for that.

Advantage of mikrotik is, that I don't have necessarily to depend 
upon snmp - It has good router scripting, and I can prepare my own 
format (even rebol blocks ;-) of output ... and some folks do so 
with the router scripting language available ....

like snmp

IIRC OID is used for snmp (simple network management protocol), and 
this one is really big and important ...
