This is a list of presently defined Automake conditionals in our infrastructure. They can be used to enable / disable build steps such as testing and enabling or disabling build targets depending on the user’s configuration.

• WANT_MORPHOLOGY: --enable-analysers, default=yes
  Used to enable the default set of analysers, which is: analyser-gt-desc.xfst, analyser-gt-norm.xfst and analyser-disamb-gt-desc.hfst
• WANT_GENERATION: --enable-generators, default=yes
  Used to enable the default set of generators, which is: generator-gt-desc.xfst and generator-gt-norm.xfst
• WANT_TRANSCRIPTORS: --enable-transcriptors, default=yes
  Used to enable compilation of transcriptors, that is, converters between different types of textual representations, such as dates expressed as text or digits.
• WANT_SPELLERS: --enable-spellers, default=no
  Used to enable building of spellers in general
• WANT_SPELLERAUTOMAT: --enable-spellerautomat, default=no
  Used to enable building of the hfst speller automat
• WANT_VOIKKO: --enable-voikko, default=no
  Used to enable building of the voikko speller = zhfst file
• WANT_HUNSPELL: --enable-hunspell, default=no
  Used to enable building of Hunspell dic and aff files. Not yet functional since this build is not implemented.
• WANT_FST_HYPHENATOR: --enable-fst_hyphenator, default=no
  Used to enable building of hyphenating tools. Not functional because it is not implemented yet.
• WANT_GRAMCHECK: --enable-grammarchecker, default=no
  Used to enable building of grammar checkers. Is only usable in sme, the only language with a grammar checker at the moment.
• WANT_DICTIONARIES: --enable-dicts, default=no
  Used to enable building of transducers targeted at electronic dictionaries
• WANT_OAHPA: --enable-oahpa, default=no
  Used to enable building of transducers targeted at Oahpa
• WANT_PHONETIC: --enable-phonetic, default=no
  Used to enable building of transducers for conversion from text to IPA
• WANT_APERTIUM: --enable-apertium, default=no
  Used to enable building of transducers and constraint grammar files used for machine translation in Apertium

Example of how to use them:

if WANT_MORPHOLOGY
GT_ANALYSERS_HFST+=analyser-gt-desc.hfst \
				   analyser-gt-norm.hfst \
				   analyser-disamb-gt-desc.hfst
endif # WANT_MORPHOLOGY

This ensures that we build Hfst analysers only if the user has enabled analysers. Analysers are enabled by default, so the usefulness of this is rather the oposite: the user can explicitly disable analysers, e.g. to speed up compilation time when building spellers. In that case, the conditional will make sure that the analysers are not built.
