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" # stringopt:DESCR => As for stringopt: with a description for the 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. That 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 # which defaults 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. # # 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: # - [proj-opt-truthy FLAG] # - [proj-opt-if-truthy FLAG {THEN} {ELSE}] # # Non-boolean (i.e. string) flags: # - [opt-val FLAG ?default?] # - [opt-str ...] - see the docs in ./autosetup/autosetup # # [proj-opt-was-provided] can be used to determine whether a flag was # explicitly provided, which is often useful for distinguishing from # the case of a default value. ######################################################################## set allFlags { # Structure: a list of M {Z} pairs, where M is a descriptive # option group name and Z is a list of X Y pairs.
