It is sourced because that is # the only way to change the shell variables in the calling # environment. # # Sourcing makes the shell script more delicate for the following reasons: # # * temporary variables are automatically set in the calling # environment! WORKAROUND: we need to unset all them after using # them to avoid polluting the calling environment; # # * not only the exit value of the script, but the exit value of each # command we execute, might be interpreted by the calling # environment. Typically, the calling environment might be using the # shell errexit option ('set -e') in bash parlance, which causes the # shell to exit if any command returns an error value. If this were # a normal script, this option would mean that the shell would exit # if the return value of the whole script were an error value; but # because we are sourced, it is as all the commands in this script # were executed directly in the calling environment, so *all* values # returned by *all* commands must be non-error. [this all typically # happens in rpm builds, where scripts are run with the errexit # option so that errors in scripts abort the build, and now if a # script sources GNUstep.sh, then we are exactly in this situation - # if any command inside GNUstep.sh returns an error value (even if # GNUstep.sh as a whole would be happy and return succes), the whole # rpm build process aborts!]. WORKAROUND: we must make sure all # commands return success - last resorts hacks like 'command || :' # which always returns success whatever command returns. # # If we're running in zsh (auch!) make sure we're using -y # (SH_WORD_SPLIT) else our path manipulations won't work. if [ -n "$ZSH_VERSION" ]; then # If -y is not already set, set it and remember that we # need to set it back to what it was at the end. if ( setopt | grep shwordsplit > /dev/null ); then :; else set -y GS_ZSH_NEED_TO_RESTORE_SET=yes fi fi # # Set the GNUstep system root and local root # # # Read our configuration files # # Determine the location of the system configuration file if [ -z "$GNUSTEP_CONFIG_FILE" ]; then GNUSTEP_CONFIG_FILE=@GNUSTEP_CONFIG_FILE@ fi # Determine the location of the user configuration file if [ -z "$GNUSTEP_USER_CONFIG_FILE" ]; then GNUSTEP_USER_CONFIG_FILE=@GNUSTEP_USER_CONFIG_FILE@ fi # Read the system configuration file if [ -f "$GNUSTEP_CONFIG_FILE" ]; then .
