# run_magicnull.sh -- launch magic in batch / no-GUI mode (-dnull) from the build tree.
# Generated by configure from scripts/run_magicnull.sh.in.
#
# PURPOSE
# Run the just-built magic with the null graphics device -- no X display, fully
# scriptable -- without `make install`. Like run_magic.sh it stages
# ${builddir}/CAD_DIR (symlinks) on first run and exports CAD_ROOT so magic
# finds its sys files and Tcl runtime there. Uses the self-contained
# "magicdnull" (no external wish/Tk needed).
#
# USAGE
# ./run_magicnull.sh # interactive Tcl prompt
# ./run_magicnull.sh foo.mag # load a layout, batch
# Interactive (tty) use sources the Tcl startup (magic.tcl) automatically from
# CAD_ROOT. For a non-interactive script piped on stdin, source it yourself:
# printf 'source %s/magic.tcl\n<commands>\n' "$CAD_ROOT/magic/tcl" \
# | ./run_magicnull.sh
#
# ENVIRONMENT OVERRIDES (all optional; each wins over the baked default)
# CAD_ROOT reuse an alternate runtime tree instead of staging $builddir/CAD_DIR
# TCLSH tclsh matching this build's Tcl (--with-tcl); for diagnostics
# MAGIC_BUILDDIR MAGIC_SRCDIR build/source tops (default: baked-in absolutes)
# (WISH/MAGIC_WISH are irrelevant here -- there is no Tk in -dnull mode.)
# Inherited values are sanity-checked; problems print as stderr warnings.
# See magic_run_common.sh for the authoritative list and defaults.
