# TODO:
|
|
#
|
|
# This has the potential to grow into something with a really big life
|
|
# of its own, which might or might not be a good thing. Nevertheless,
|
|
# here are some enhancements that will probably be requested some day
|
|
# and are worth keeping in mind (assuming this takes off):
|
|
#
|
|
# - A command to re-read / re-load the SConscript files. This may
|
|
# involve allowing people to specify command-line options (e.g. -f,
|
|
# -I, --no-site-dir) that affect how the SConscript files are read.
|
|
#
|
|
# - Additional command-line options on the "build" command.
|
|
#
|
|
# Of the supported options that seemed to make sense (after a quick
|
|
# pass through the list), the ones that seemed likely enough to be
|
|
# used are listed in the man page and have explicit test scripts.
|
|
#
|
|
# These had code changed in Script/Main.py to support them, but didn't
|
|
# seem likely to be used regularly, so had no test scripts added:
|
|
#
|
|
# build --diskcheck=*
|
|
# build --implicit-cache=*
|
|
# build --implicit-deps-changed=*
|
|
# build --implicit-deps-unchanged=*
|
|
#
|
|
# These look like they should "just work" with no changes to the
|
|
# existing code, but like those above, look unlikely to be used and
|
|
# therefore had no test scripts added:
|
|
#
|
|
# build --random
|
|
#
|
|
# These I'm not sure about. They might be useful for individual
|
|
# "build" commands, and may even work, but they seem unlikely enough
|
|
# that we'll wait until they're requested before spending any time on
|
|
# writing test scripts for them, or investigating whether they work.
|
|
#
|
|
# build -q [??? is there a useful analog to the exit status?]
|
|
# build --duplicate=
|
|
# build --profile=
|
|
# build --max-drift=
|
|
# build --warn=*
|
|
# build --Y
|
|
#
|
|
# - Most of the SCons command-line options that the "build" command
|
|
# supports should be settable as default options that apply to all
|
|
# subsequent "build" commands. Maybe a "set {option}" command that
|
|
# maps to "SetOption('{option}')".
|
|
#
|
|
# - Need something in the 'help' command that prints the -h output.
|
|
#
|
|
# - A command to run the configure subsystem separately (must see how
|
|
# this interacts with the new automake model).
|
|
#
|
|
# - Command-line completion of target names; maybe even of SCons options?
|
|
# Completion is something that's supported by the Python cmd module,
|
|
# so this should be doable without too much trouble.
