# Note that boolean flags...
# A very long story made short, autosetup's --flag handling has
# some behaviors which make it impossible to implement 100% identical
# flags, compared to the historical autotools build. The differences
# are documented here:
#
# 1) Are in the form flagname (default=false) or flagname=0 (false) or
# flagname=1 (true).
#
# 2) If they default to false, the actual flag mapped to them is
# --enable-FLAG.
# 1) --debug is used by autosetup itself, so we have to rename it to
# --with-debug. We cannot use --enable-debug because that is, for
# autosetup, and alias for --debug=1.
#
# 3) If they default to true, the actual flag mapped to them is
# --disable-FLAG.
# 2) In autosetup, all flags starting with (--enable, --disable) are
# forced to be booleans and received special handling in how they're
# resolved. Because of that we have to rename:
#
# 4) For boolean options, configure will accept any of --flag, --enable-flag,
# or --disable-flag. Unfortunately, it reserves --debug for its own use.
# 2.1) --enable-tempstore[=no] to --with-tempstore[=no].
#
# 5) Mapping with their full name, e.g. enable-foo=1 or disable-bar=0,
# will lead to breakage in calls to either [opt-bool foo] or
# [opt-bool enable-foo].
#
# (2) and (3) mean that the help text for flag=1 should start with
# "Disable" and flag=0 should start with "Enable".
#
# In trying to helpfully map between --foo/--enable-foo/--disable-foo,
# it ends up creating some degree of confusion.
#
# Reminders about flag handling quirks..
#
# 1) autosetup treats prefixes of 'enable' and 'disable' specially,
# leading to some incompatibilities with the historical sqlite3
# configure script flags.
#
# Defining non-boolean flags named enable-foo requires different
# downstream handling of those flags. e.g.
#
# enable-tempstore:=no => {...}
#
# requires that [opt-val enable-tempstore], rather than [opt-val
# tempstore], be used, which is in constrast to boolean flags, where
# [opt-bool flag] must be used instead of [opt-bool enable-flag].
#
# Also, passing --enable-tempstore with no value (to presumably get the
# default value) breaks: autosetup tries to find a boolean-type tempstore
# flag and cannot, so it complains that flag --tempstore is not defined.
# i.e. --enable-tempstore requires that it be passed a value.
#
# An awkward workaround for that, discovered only by random trial and
# error, is to define both {tempstore=1} and {enable-tempstore:}. With
# that in place --enable-tempstore, with no value, works as expected
# (why? Nobody knows!) but --tempstore can only ever be legally passed
# a boolean value (0, 1, yes, no, enabled, disabled). It does,
# however, pollute the --help with a synthetic --disable-tempstore
# option. After an hour of fighting with it, a switch from
# --enable-tempstore to --with-tempstore seems like the better
# approach, in that it doesn't lead to a losing fight with autosetup.
