Useful linux script when hosting PBEM.

[guybrush threepwood]

Hi there,

I just made a somewhat useful script for my own purposes and thought I would share it here.

The script (which is a simple bash script) is invoked as:

dom2-host-game my-game-name

The script then carefully checks (using output from dom2 --verify) whether all .2h files are alright, that there are no stale turns, etc. If everything is fine, it then hosts.

Let me know if anyone finds it useful :-)


Install by putting the following inside ~/bin/dom2-host-game (you might need to change the variable DOMINIONS2EXECUTABLE):

code:

---

#!/bin/bash



DOMINIONS2SAVEDIR=$HOME/dominions2

DOMINIONS2EXECUTABLE=/usr/local/bin/dom2

HOSTFLAGS="--host -xxx --statfile"

#could add --scoredump, but scoredump outputs info even though statistics on other nations is off!!!



if [ $# -ne 1 ]; then

    echo Usage: $0 gamename

    exit 1

fi



GAMENAME=$1



GAMEDIR="$DOMINIONS2SAVEDIR/$GAMENAME"



if [ ! -d "$GAMEDIR" ]; then

    echo Game \"$GAMENAME\" does not appear to exist in $DOMINIONS2SAVEDIR

    exit 1

fi



OK=1;

for nationtrn in $GAMEDIR/*.trn; do

    nationname=`basename $nationtrn .trn`

    file_2h=$GAMEDIR/$nationname.2h

    if [ ! -f $file_2h ]; then

        echo missing .2h file for $nationname

        OK=0

    fi

done



if [ $OK -eq 0 ]; then

    exit 1

fi



#remove old .chk files

rm -f $GAMEDIR/*.chk



#invoke dom2 -verify to produce new .chk files.

$DOMINIONS2EXECUTABLE --verify $GAMENAME

if [ ! $? ]; then

    echo Errors when invoking \"dom2 --verify $GAMENAME\"

    exit 1

fi



# A non-existing ftherlnd.chk file means something was wrong with the ftherlnd file.

if [ ! -f $GAMEDIR/ftherlnd.chk ]; then

    echo Something is wrong with the ftherlnd file.

    exit 1

fi



#ftherlnd defines turn number and game number:

FATHERGAMENUMBER=`grep gamenbr $GAMEDIR/ftherlnd.chk|sed 's/ *//'|cut -d ' ' -f 2`

FATHERTURNNUMBER=`grep turnnbr $GAMEDIR/ftherlnd.chk|sed 's/ *//'|cut -d ' ' -f 2`



#Now, let us check all the chk files.

OK=1;

for nationtrn in $GAMEDIR/*.trn; do

    nationname=`basename $nationtrn .trn`

    file_chk=$GAMEDIR/$nationname.chk

    GREPCHK=`/bin/grep '2h file is OK!' $file_chk`

    if [ "$GREPCHK" != "2h file is OK!" ]; then

        echo Something is wrong with $nationname.2h

        OK=0

    else

        GAMENUMBER=`grep gamenbr $file_chk|sed 's/ *//'|cut -d ' ' -f 2`

        TURNNUMBER=`grep turnnbr $file_chk|sed 's/ *//'|cut -d ' ' -f 2`

        if [ "$GAMENUMBER" != "$FATHERGAMENUMBER" ]; then

            echo $nationname.2h file appears to belong to a different game!

            OK=0

        else

            if [ "$TURNNUMBER" != "$FATHERTURNNUMBER" ]; then

                echo $nationname.2h file appears to be from a wrong turn. Maybe $nationname did not play their turn yet.

                OK=0

            fi

        fi

    fi

done



if [ $OK -eq 0 ]; then

    exit 1

fi



$DOMINIONS2EXECUTABLE $HOSTFLAGS $GAMENAME



if [ $? ]; then

    echo Hosted $GAMENAME succesfully.

    exit 0
