 Posted: Mon Dec 25, 2023 7:01 pm Post subject: retrieving $CATEGORY and $PN |
 |
|
Here's a local script that starts as: | Code: | if [ -z $1 ]; then
echo param 1 is empty\; [package_category/]package_name[-x.y.z-abcd][:slot][::repo] expected
else
tmpfile=$(mktemp /tmp/mrgl.XXXXXX)
if ! emerge --nodeps -p $1>$tmpfile; then
echo error emerging package $1 #not detected
echo $0 cancelled
rm $tmpfile
else
fullpckname=$(grep ebuild $tmpfile|awk '{ print $4 }')
rm $tmpfile
echo package $fullpckname requested
catname=$(dirname $fullpckname)
pckname=$(basename $fullpckname)
|
where $catname = $CATEGORY.
Unfortunately $packname = $PF = ${PN}-${PVR}.
How to extract $PN?
Thks 4 ur attention, interest & support.

I think you're looking for qatom.
Try with | Code: | | qatom -F '%{PN}' "$fullpckname" |
For what purpose you use your script, if I may ask?

... or alternatively *cough*, app-portage/iwdevtools:
| Code: | $ atomf "name = %n\nversion = %V\nrevision = %R\n" category/packagename-1.0.0-r1
name = packagename, version = 1.0.0, revision = 1
$ cat test.sh
#!/usr/bin/env bash
. "$(pkg-config iwdevtools --variable=atomf)" || exit
atomset 'category/packagename-1.0.0-r1'
echo "${PF}"
echo "${CATEGORY}"
echo "${PN}"
echo "${PV}"
$ ./test.sh
packagename-1.0.0-r1
category
packagename
1.0.0 |

Currently testing... Nice.
Can't refrain from saying how crazy it sounds to me that emerge command can not output all lexical atoms that compose a valid CATEGORY/PN-PV-PR::SLOT::REPOSITORY

As far as LTO is concerned here, file/package size is an easy decision helper.
You'd be surprised how many packages have LTO cancelled here because of size increase: | Code: | grep "#bigger lto-full-bfd.conf" /etc/portage/package.env/* | wc -l
123 |
Or how many don't bother | Code: | grep "#unchanged lto-full-bfd.conf" /etc/portage/package.env/* | wc -l
311 |
LTOized here | Code: | grep lto-full-bfd.conf /etc/portage/package.env/*|awk '{ print $1" "$2 }' | grep lto-full-bfd.conf | wc -l
801 |
Sorry I didn't scroll back enough...
qatom is the right thing indeed!
