build: add run_magic*.sh launchers to run magic from the build tree
Four configure-generated launch scripts let you run magic straight from the
build directory without `make install`:
* run_magic.sh -- GUI magic (Cairo/X11)
* run_magicnull.sh -- batch / no-GUI (-dnull)
* run_magic_gdb.sh -- magic under gdb
* run_magic_valgrind.sh -- magic under valgrind
magic resolves its runtime files through a single $CAD_ROOT root
($CAD_ROOT/magic/{sys,tcl}), but in the build tree they are scattered across
build/ (generated tech, .magicrc, magic.tcl, tclmagic, execs) and source/
(colormaps, dstyles, glyphs, fonts, tcl scripts). On first run each launcher
self-stages ${builddir}/CAD_DIR as a symlink tree in that layout (no copies,
always current) via the shared scripts/magic_run_common.sh, exports
CAD_ROOT=${builddir}/CAD_DIR, and execs the right binary. This pairs with the
preceding commit that made the C launchers honor CAD_ROOT.
magic_stage() is idempotent and re-runs on every launch. Most staged entries
are files, but the bitmaps entry links a *directory*, so it uses `ln -sfn`
(--no-dereference; also accepted by BSD ln): a plain `ln -sf` would, on a second
run, dereference the existing symlink-to-directory and drop the new link *inside*
the target -- a magic/bitmaps/bitmaps self-loop in the source tree that trips up
find/tar/cp -r.
Verified: ./run_magicnull.sh self-stages (30 sys + 24 tcl symlinks) and runs --
`tech load scmos` reports 13 planes -- straight from the build dir. gitignore
covers the generated scripts and the CAD_DIR tree.

# PURPOSE
|
|
|
|
|
# Debug the just-built magic without `make install`. Stages ${builddir}/CAD_DIR
|
|
|
|
|
# (symlinks) on first run, exports CAD_ROOT, then starts gdb on the self-contained
|
|
|
|
|
# "magicexec". Symbols come straight from the build tree.

# USAGE

|
|
|
# ./run_magic_gdb.sh [gdb-opts...] [-- [magic-args...]]
|
|
|
|
|
#
|
|
|
|
|
# A "--" separates gdb's own options from magic's:
|
|
|
|
|
# ./run_magic_gdb.sh # plain interactive gdb
|
|
|
|
|
# ./run_magic_gdb.sh foo.mag # no "--" => all args go to magic
|
|
|
|
|
# ./run_magic_gdb.sh -tui -- foo.mag # gdb gets -tui, magic gets foo.mag
|
|
|
|
|
# ./run_magic_gdb.sh -ex run -- -dnull # gdb runs immediately; magic -dnull
|
|
|
|
|
# With no "--", every argument is passed to magic (the common case).
|
|
|
|
|
#
|
|
|
|
|
# For batch/no-GUI debugging point it at the null device: ... -- -dnull

# CAD_ROOT reuse an alternate runtime tree instead of staging $builddir/CAD_DIR
