SN 5.0 html docs

[Doug Fraser]

Hello,

Attached below is a simple shell script and a description of a
file list that it uses to generate 'import' files that can be
used to manage pseudo projects that can be stored in CVS.
It allows developers to share a common files list with relative
paths and generates full local paths useable by snavigator.

Enjoy.

Embellishments and feedback welcome. Send it to the whole group.

Doug

So, our source tree is broken up into subdirectories that
support individual targets (boards), with each subdirectory
broken into at the least; src, include, drv, and build
The relative tree might look like this:

     ./product/board1
     ./product/board2
     ./product/board3

and a given board would look like:

     ./product/board1/src
     ./product/board1/drv
     ./product/board1/include
     ./product/board1/build

and we also have a common area for shared headers and build scripts

     ./common/include

We added a subdirectory to each board, named snlst.
It holds one or more files that list the source and include
files used to create a process that runs on that board.
So add another directory

     ./product/board1/snlst

The contents and format of that file are as follows:

src/ThisClass.cc
src/ThatClass.cc
src/AnotherClass.cc
src/SomeClient.cc
src/BigServer.cc
../common/include/BaseClass.h
include/ThisClass.h
include/ThatClass.h
include/AnotherClass.h
include/SomeClient.h
include/BigServer.h

If you are currently in the board directory (for example, ./product/board1),
you can run the following script (I call it snrun), and it will display a
menu
listing the files that you have created in the snlst directory, and if you
select a valid file, it creates a /tmp/file (unique) that provides full path
names to your source suitable for snavigator. It then starts snavigator with
a temporary project file. When you close out the session, all the files are
removed.

This script is written in KSH, that is what I use, but should port easily to
other shells as well.

#!/bin/ksh

if [ ! -d snlst ]
then
    echo No snlst directory in this node.
    exit
fi

PS3="select product> "
FILELST=`find snlst -maxdepth 1 -type f -print`
select PRODUCT in $FILELST
do
    case $PRODUCT in
        $FILELST)
	break
        ;;

	*)
	;;
    esac

    if [ ! -d $PRODUCT ]
    then
        PRODUCT=`basename $PRODUCT`
        break
    fi

done

print "You selected $REPLY ) $PRODUCT"

HERE=`pwd`/
TMP=/tmp/snrun

# create and chmod the tmp dir. Redirect to /dev/null if it
# already exists....
mkdir ${TMP} > /dev/null 2>&1
chmod 777 ${TMP} > /dev/null 2>&1

IMPORT=${TMP}/${PRODUCT}$$.import
PROJ=${TMP}/${PRODUCT}$$.proj
LIST=${HERE}/snlst/${PRODUCT}

trap "rm ${IMPORT} ${PROJ} > /dev/null 2>&1" EXIT INT TERM QUIT

# Yup. That is a magic sed script. The contents of the first [] pair
# is a tab and a space
sed -e 's/^[ 	]*//' -e '/^$/d' -e "s?^?${HERE}?" ${LIST} | while read F
do
if [ -f ${F} ]
then
print ${F}
fi
done > ${IMPORT}

snavigator -import ${IMPORT} ${PROJ}
