i want to find a way when i update config e.g. Base-Config from V1.5 to V1.6 to replace /system note → only Base-Config value (1.5->1.6)
its not possible to replace the whole note because e.g. the first router has Base-Config and VPN the second has Base-Config and something else
there is no problem to change note structure e.g. from -Base-Config=V1.5 to -Base-Config=1.5 or something else.
Is it possible?
Below code produces the below. You can then set it as the note message. It’s limited to 4096 characters (including new lines).
local note [sys note get note]
put $note
local baseconfigPosition [find $note "Base-Config"]
local pre [pick $note 0 ($baseconfigPosition+12)]
local oldVersion [pick $note ($baseconfigPosition+12) [find $note "\r\n" ($baseconfigPosition+12)]]
local after [pick $note ($baseconfigPosition+12+[len $oldVersion]) [len $note]]
local newVersion "V1.10"
local newNote ($pre.$newVersion.$after)
put $newNote
What you’re doing is loading existing note in a variable, then using :pick to split the note into three parts, a “pre” part, the oldversion and an “after” part.
You can then concatenate the pre and after parts along with the new version.
You are the best!!! it perfectly works!!!
Just to understand what you just did:
#Get Note
local note [sys note get note]
#Put note (can be removed)
put $note
#Find where is Base-Config (in my example character 15)
local baseconfigPosition [find $note "Base-Config"]
#Set to pre (from note character 0 to note baseconfigPosition (+12 is for the length of characters from B to = )
# So in my example pre is (Router Mode\r\n- Base-Config=)
local pre [pick $note 0 ($baseconfigPosition+12)]
#set to old version after "pre" up to first /r/n (in my example V1.5)
local oldVersion [pick $note ($baseconfigPosition+12) [find $note "\r\n" ($baseconfigPosition+12)]]
#set to "after" after /r/n up to the end
local after [pick $note ($baseconfigPosition+12+[len $oldVersion]) [len $note]]
local newVersion "V1.10"
local newNote ($pre.$newVersion.$after)
put $newNote
Is it right?
I `ve changed a little bit (removed dots etc)
local note [/system note get note]
local baseconfigPosition [find $note "Base-Config"]
local pre [pick $note 0 ($baseconfigPosition+12)]
local oldVersion [pick $note ($baseconfigPosition+12) [find $note "\r\n" ($baseconfigPosition+12)]]
local after [pick $note ($baseconfigPosition+12+[len $oldVersion]) [len $note]]
local newVersion "V1.10"
/system note set note="$pre$newVersion$after"
You can possibly make this into a generic function to change any value, assuming an .ini like key=value format.
i.e.
global editNote do={
#first argument is the key, second is the new value
local key $1
local newValue $2
#Get Note
local note [sys note get note]
#Find where is Base-Config (in my example character 15)
local keyPosition [find $note $key]
#key length + 1 for the equal sign
local keyLength ([len $key]+1)
#Set to pre
local pre [pick $note 0 ($keyPosition+$keyLength)]
#get old value, just to calculate its length
local oldValue [pick $note ($keyPosition+$keyLength) [find $note "\r\n" ($keyPosition+$keyLength)]]
#oldValue length
local oldValueLength [len $oldValue]
#set to "after" after /r/n up to the end
local after [pick $note ($keyPosition+$keyLength+$oldValueLength) [len $note]]
local newNote ($pre.$newValue.$after)
put $newNote
}
using it :
[admin@sini2] > put [sys note get note]
Router Mode
- Base-Config=V1.5
- VPN=V1.8
- etc,etc....
[admin@sini2] > $editNote VPN "custom version"
Router Mode
- Base-Config=V1.5
- VPN=custom version
- etc,etc....
