Ebuild 2 Overlay

Ebuild2overlay is available. This script comes in nice after grabbing an ebuild (e.g. from bugzilla) and not wanted to go thorough all the commands of putting it in the overlay. Adjust the keyword, and overlay variable to make itwork for you.

ebuild2overlay <category> <package.ebuild>

v.2 – I’ve added keyword support and fixed a few bugs. Thanks to the guys at comp.unix.shell for helping out.

v.3. – Cleaned up the code. Added checks for required tools. Wasn’t able to fix the remotedirectory bug. From what Ican tell you should be able to, “ebuild2overlay <category> </path/to/ebuild>” but currently you have to be in the current directory to use it.

#!/bin/bash
# ebuild2overlay
#   grabs an ebuild and adds it the local overlay
#   adds architecture if needed
#   ebuild-overlay does not add patchs, add these to the "files" directory
#    in the package’s overlay directory.

# Todo/Bugs:
#   Allow script to run if ebuild is in separate directory.
#   Directory check for category can fail for incomplete categories -
#   (i.e "app-edi")
#   PKGDIR filter fails for revisioned ebuilds.
#   "ebuild2overlay category/package" argument possible?

CATEGORY=$1
EBUILD=$2
PORTDIR=/usr/portage

# Notes

# Filters (looks like it’s best to bash filters)

# Bash Filter – Remove the shortest matching pattern from right in variable
# EBUILD starting with ‘-’ followed by any character "*".
# "${EBUILD%-*}"

# Awk
#PKGDIR=$(echo $EBUILD | awk -F- ‘{print $1 "-" $2}’)
