<h1>KISS tips and tricks</h1>
<p>More blogs about <a href="//kisscommunity.bvnf.space/">KISS</a> are good. I hope this will give you some ideas for your system.</p>
<ol>
<h2><li>Hooks</li></h2>
<p>My <code>$KISS_HOOK</code> file begins with:
<code><pre>PKG=$2
DEST=$3
KISS_TMPDIR=${KISS_TMPDIR:-/tmp}
case $1 in</pre></code> as well as a copy of <code>log()</code> from kiss itself.</p>
<p>Firstly, one to update the man page database after installation. This is quicker than running just plain <code>makewhatis</code> because it only updates entries for the added files.
<code><pre>post-install)
man="$(kiss-manifest "$PKG" | grep '/usr/share/man/man./.')" || :
# shellcheck disable=2086
[ "$man" ] && {
log "$PKG" "Updating manpage database"
makewhatis -d "$KISS_ROOT/usr/share/man" $man
} || :
;;</pre></code>Note that I call <code>kiss-manifest</code> directly. Calling kiss from within a hook can be bad.</p>
<p>This is probably the most useful one - gives me a shell in the build directory if something goes wrong.
<code><pre>build-fail)
printf "\a"
log "$PKG" "Dropped into subshell"
sh >/dev/tty
;;</pre></code>I also have a patched <code>kiss</code> which can continue and finish a build that was stopped in this way.</p>
<p>One to set my terminal title, a classic.
<code><pre>queue-status)
# Set the terminal title
[ -t 2 ] && {
printf '\033]0;kiss: %s (%d/%d)\a' \
"$PKG" "${3:-?}" "${4:-?}" >&2
}
;;</pre></code>
And another classic to log the build duration:
<code><pre>pre-build)
cat /proc/uptime > "$KISS_TMPDIR/_kiss_start"
;;
post-build)
set +e
IFS=. read -r _start _ < "$KISS_TMPDIR/_kiss_start"
IFS=. read -r _end _ < /proc/uptime
rm -f "$KISS_TMPDIR/_kiss_start"
(
_s=$((_end - _start))
_h=$((_s / 60 / 60 % 24))
_m=$((_s / 60 % 60))
[ "$_h" = 0 ] || _u="${_u}${_h}h "
[ "$_m" = 0 ] || _u="${_u}${_m}m "
log "$PKG" "Build finished in ${_u:-${_s}s}"
)
set -e
;;</pre></code></p>
<p>By the way:
<code><pre>pre-update|post-update)
# $2 is not $PKG for this hook
unset PKG
;;</pre></code></p>
<h2><li>Shell functions</li></h2>
<p>To <code>cd</code> into a package directory:
<code><pre>kisscd () {
_r="$(kiss search "$@" | sed 1q)"
[ "$_r" ] && cd "$_r"
unset _r
}</pre></code></p>
<p>To quickly view a package build file:
<code><pre>kissb () {
_r="$(kiss search "$1" | sed 1q)"
shift
[ "$_r" ] && less "$@" "$_r/build"
unset _r
}</pre></code></p>
</ol>
<p>Let me know your own useful functions.</p>
