Get package name and corr. data from file - bash

Question

I've been banging my head lately,trying to parse dumpsys output.
Here is the output:

I want to get the package name and the corresponding extras={}
for each of them.
For example:
pkg:com.android.systemui
extras={
.....
}
So far I've tried:
dumpsys notification | awk '/pkg=/,/\n}/'
But without any success.
I'm a newbie to awk,and if possible I want to do it with awk or perl.Of course,any other tool like sed or grep is fine by me too,I just wanna parse it somehow.
Can anyone help me?

Answer 1

If you have GNU awk, try the following:
awk -v RS='(^|\n)NotificationRecord\\([^=]+=' \
'NF { print "pkg:" $1; print gensub(/^.*\n\s*(extras=\{[^}]+\}).*$/, "\\1", 1) }' file
-v RS='(^|\n)NotificationRecord\\([^=]+=' breaks the input into records by lines starting with NotificationRecord( up to and including the following = char.
In effect, that means you get records starting with the package names (com.android.systemui, ...`)
NF is a condition that only executes the following block if it evaluates to nonzero; NF is the count of fields in the record, so as long as at least 1 field is present, the block is evaluated - in effect, this skips the implied empty record before the very first line.
print "pkg:" $1 prints the package name, prefixed with literal pkg:.
gensub(/^.*\n\s*(extras=\{[^}]+\}).*$/, "\\1", 1) matches the entire record and replaces it with the extras property captured via a capture group, effectively returning the extras property only.

Answer 2

I would suggest perl over awk, because you'll be storing whether you're inside the extras=... block in a variable:
dumpsys notification | perl -lne '
print $1 if /^Notif.*?: pkg=(\S+)/;
$in_extras = 0 if /^ \}/;
print if $in_extras;
$in_extras = 1 if /^ extras=\{/'
Oh, if you want the extra pkg: and extras= text, slight modification:
dumpsys notification | perl -lne '
print "pkg: $1" if /^Notif.*?: pkg=(\S+)/;
$in_extras = 1 if /^ extras=\{/;
print if $in_extras;
$in_extras = 0 if /^ \}/;'

Answer 3

Sed version:
dumpsys notification |\
sed -n 's/.*pkg=\([^ ]*\).*/pkg:\1/p;/^ extras={$/,/^ }$/s/^ //p'
I'm assuming you always have two spaces in front of extras={ and } and you also want to remove these spaces.
