This repository is an external Gentoo ebuild repository for installing Precizer through Portage

Precizer is a lightweight, high-performance CLI tool written in C for file integrity verification and comparison. It walks directory trees, calculates SHA512 checksums, and stores the results in an SQLite database. Databases can be compared with each other to find missing files and files with different contents

The tool is useful for validating synchronization results, backups, and Disaster Recovery scenarios. Precizer does not modify, delete, or move the files being checked. All working data is written only to the Precizer database

Root privileges are required for the following commands

emerge --ask --noreplace dev-vcs/git
install -d /etc/portage/repos.conf
cat >/etc/portage/repos.conf/precizer.conf <<'EOF'
[precizer]
location = /var/db/repos/precizer
sync-type = git
sync-uri = https://github.com/precizer/gentoo-overlay.git
auto-sync = yes
EOF
emaint sync --repo precizer

Precizer installation and command availability verification are performed as follows

emerge --ask app-forensics/precizer
precizer --version

The overlay is synchronized first

emaint sync --repo precizer

The package is then updated in the usual way

emerge --ask --update app-forensics/precizer

The test USE flag and the test Portage feature are used for an update that includes the test phase

USE="test" FEATURES="test" emerge --ask --update app-forensics/precizer

USE=test permits the ebuild test phase, while FEATURES=test enables its execution during the build

emerge --sync also synchronizes this repository because auto-sync = yes is enabled for it

Precizer is removed through Portage with the following command

emerge --ask --depclean app-forensics/precizer

After Precizer has been removed, the configuration and local overlay copy are removed as follows

rm -f /etc/portage/repos.conf/precizer.conf
rm -rf /var/db/repos/precizer

New Precizer versions, Manifest updates, and ebuild verification are documented in the contributor guide
