And I of course forgot to include the little script once written for littler; now below.

For Rcpp and RInside, I wrote little ad-hoc release helper scripts to also run doxygen, copy vignettes and tarballs to webfolders etc pp. If you do that, you have a hook -- but then you'd have to run this once pre-commit / build.

Scripts can help. Somewhat.


PS The ad-hoc script 'bootstrap' from littler is below.

#!/bin/bash -e

call_svnversion() {

    svnrevision=`LC_ALL=C svn info | awk '/^Revision:/ {print $2}'`     svndate=`LC_ALL=C svn info | awk '/^Last Changed Date:/ {print $4,$5}'`


    if [ "$svnrevision" != "" ]; then

	if [ "$svndate" != "" ]; then
	    cat <<EOF > svnversion.h

// Do not edit!  This file was autogenerated 
//      by $0 
//      on $now

// svnrevision and svndate are as reported by svn at that point in time, // compiledate and compiletime are being filled gcc at compilation

#include <stdlib.h>  

static const char* svnrevision = "$svnrevision";
static const char* svndate = "$svndate";
static const char* compiletime = __TIME__;
static const char* compiledate = __DATE__;



if [ "$#" -ge 0 ]; then

    if [ "$1" = "--svnversion" ]; then

        # added hoops: make sure we only call this when we have a 
	# svn binary in the path ... so that this does not get called
	# on machines that do not have svn
	set +e
	svnprog=`type -p svn`
	set -e
	if [ "${svnprog}" != "" ]; then


test -f svnversion.h || call_svnversion
