|
# Regarding flag compatibility with the historical autotool configure
|
|
# script:
|
|
#
|
|
# 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) --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.
|
|
#
|
|
# 2) In autosetup, all flags starting with (--enable, --disable) are
|
|
# forced to be booleans and receive special handling in how they're
|
|
# resolved. Because of that we have to rename:
|
|
#
|
|
# 2.1) --enable-tempstore[=no] to --with-tempstore[=no].
|
|
#
|
|
########################################################################
|
|
# A gentle introduction to flags handling in autosetup
|
|
#
|
|
# Reference: https://msteveb.github.io/autosetup/developer/
|
|
#
|
|
# All configure flags must be described in an 'options' call, which
|
|
# must appear very early on in this script. The general syntax is:
|
|
#
|
|
# FLAG => {Help text}
|
|
#
|
|
# Where FLAG can have any of the following formats:
|
|
#
|
|
# boolopt => "a boolean option which defaults to disabled"
|
|
# boolopt2=1 => "a boolean option which defaults to enabled"
|
|
# stringopt: => "an option which takes an argument, e.g. --stringopt=value"
|
|
# stringopt2:=value => "an option where the argument is optional and defaults to 'value'"
|
|
# optalias booltopt3 => "a boolean with a hidden alias. --optalias is not shown in --help"
|
|
#
|
|
# Autosetup does no small amount of specialized handling for flags,
|
|
# especially booleans. Each bool-type --FLAG implicitly gets
|
|
# --enable-FLAG and --disable-FLAG forms, and explicitly adding flags
|
|
# with those prefixes will force them to be boolean flags. e.g. we
|
|
# define a flag "readline", which will be interpreted in one of two
|
|
# ways, depending on how it's invoked and how its default is defined:
|
|
#
|
|
# --enable-readline ==> boolean true
|
|
# --disable-readline ==> boolean false
|
|
#
|
|
# Trying to pass --readline or --readline=1 or --readline=0 will
|
|
# result in an "unrecognized option" error, despite the the options
|
|
# call listing the flag as "readline".
|
|
#
|
|
# The behavior described above can lead lead to some confusion when
|
|
# writing help text. For example:
|
|
#
|
|
# options { json=1 {Disable JSON functions} }
|
|
#
|
|
# The reason the help text says "disable" is because a boolean option
|
|
# defaulting to true is, in the --help text, rendered as:
|
|
#
|
|
# --disable-json Disable JSON functions
|
|
#
|
|
# Whereas a bool flag which defaults to false will instead render as:
|
|
#
|
|
# --enable-FLAG
|
|
#
|
|
# Non-boolean flags, in contrast, use the names specifically given to
|
|
# them in the 'options' invocation. e.g. "with-tcl" is the --with-tcl
|
|
# flag. Autosetup may, however, choose to automatically alter the help
|
|
# text, as demonstrated here:
|
|
#
|
|
# options {
|
|
# readline=1 => {Disable readline support}
|
|
# with-readline-lib: => {Readline library}
|
|
# with-readline-inc: => {Readline include paths}
|
|
# }
|
|
#
|
|
# $ ./configure --help | grep readline
|
|
# --disable-readline disable readline support
|
|
# --with-readline-lib specify readline library
|
|
# --with-readline-inc specify readline include paths
|
|
#
|
|
# Note that it prefixed and lower-case the help message. Whether
|
|
# that's a feature or a bug can be debated.
|
|
#
|
|
# Fetching values for flags:
|
|
#
|
|
# booleans: use one of:
|
|
# - [opt-bool FLAG] is autosetup's built-in command for this, but we
|
|
# have some convenience variants:
|
|
# - [hwaci-opt-truthy FLAG]
|
|
# - [hwaci-opt-if-truthy FLAG {THEN} {ELSE}]
|
|
#
|
|
# Non-boolean (i.e. string) flags:
|
|
# - [opt-val FLAG ?default?]
