tips - Debian Perl Group tips and tricks

INTRODUCTION

This is a small guide describing functions, aliases and scripts used by Perl team members to make life easier when packaging perl modules.

Contributions are welcome.

If you think you are using an interesting script or such, feel free to add it on this page.

1. Scripts

A lot of useful scripts can be found in the pkg-perl-tools package, either as

dpt $subcommand

or in /usr/share/doc/pkg-perl-tools/examples.

2. Aliases

# download upstream tarball and import it into git-buildpackage
alias git-uscan='gbp-pull ; git-import-orig --uscan ; rm ../*.tar.gz'

# quickly edit your aliases/functions
# presumes ~/.aliases is loaded on shell startup
alias ale='vim ~/.aliases; unalias -a; source ~/.aliases'

3. Functions

# afsp = apt-file search $perl; obsolete since `dh-make-perl --locate'
function afsp {
    apt-file search $(echo "/$@" | sed -e 's|::|/|g ; s|-|/|g ; s|$|.pm|') | uniq
}

# extract package details. used in the rest below
pkg_info()
{
    dpkg-parsechangelog|grep ^$1|cut -f2 -d' '
}

# run lintian and diffstat on the package built in pbuilder result/
# directory
# package name is deduced from ./debian.
# all argumentts are given to lintian
lpdb()
{
    local PKG=`pkg_info Source:`
    local VER=`pkg_info Version:|sed 's/^.\+://'`
    local ARCH=`dpkg-architecture -qDEB_HOST_ARCH`

    local PDB=/var/cache/pbuilder/result

    local CMD="lintian $@ -I --color=auto ${PDB}/${PKG}_${VER}_${ARCH}.changes"
    echo $CMD
    $CMD

    if [ -e ${PDB}/${PKG}_${VER}.diff.gz ]; then
        echo diffstat ${PDB}/${PKG}_${VER}.diff.gz
        diffstat ${PDB}/${PKG}_${VER}.diff.gz
    else
        echo Native package.
