Trouble with sed and semicolon delimiter...

[Tom Lynch]

Greetings,

I'm having trouble with the sed portion of a bash script. I'm trying to get
all the tags from BitBake recipes. I have the following line:

SRC_URI = "git://bb/foo.git;protocol=ssh;tag=v1.1.0;lfs=0;subpath=pctrlmc/c2cmtd"

What I would like to get is the "v1.1.0" of the "tag=" portion

I'm using the following to parse, since this is a BitBake recipe, I need to account for line extensions, so I run it through a perl script first, but the entire line:

perl -pe 's/\\\n|\s{2,}/ /g' foo.bb | grep SRC_URI | grep -v '#' | sed -r 's#.*tag=(.?+)(;|\s+|\").*#\1#'

What this gets is:

v1.1.0;lfs=0;subpath=pctrlmc/c2cmtd

it's missing the semicolon delimter, if I change the sed to:

sed -r 's#.*tag=(.?+);.*#\1#'

It's still missing the first semicolon

v1.1.0;lfs=0

I need to account for other types of delimiter, thus the (;|\s+|\"), but no matter what I've tried, I can't seem to capture just the tag there. What I'm I doing wrong?

Thanks in Advance for any help!

Are you sure that's what you have? When I execute that line, I get

$ SRC_URI =
"git://bb/foo.git;protocol=ssh;tag=v1.1.0;lfs=0;subpath=pctrlmc/c2cmtd"
SRC_URI: command not found
$

(Give or take the gratuitous line-wrap inserted by Thunderbird)

I know nothing about perl, so I can't help with that.

Can you just use sed?

$
SRC_URI="git://bb/foo.git;protocol=ssh;tag=v1.1.0;lfs=0;subpath=pctrlmc/c2cmtd"
$ echo $SRC_URI | sed 's/.*;tag=//' | sed 's/;.*//'
v1.1.0
$

Yes, I should be more specific, this is the BitBake line I'm trying to parse to get the version from,
it's just an example.

v1.1.0

That is a possibility, hadn't thought of breaking it into two sed commands...

Thanks
