What's new

0.20.2


Fixes
  • Fixes a regression introduced in 0.20.1 that affected right-hand boundary checking within an underline structure
    • Specifically, rules such as VN > [+nas] / <(..)_> now work as expected

0.20.1


New Features
  • Segments and matrices can be negated in input and environment with - or ¬
    • e.g. <(..)-G> > [+str] ;; a syllable that doesn't have an off-glide is stressed
      • saj.nam => saj'nam
  • Boundaries can be used at the periphery of structures
    • Allows for boundary manipulation with all the benefits of underline structures
    • e.g. V:[-str] $ > * / _S:[+str] | #<(..)_>
      • me.da'ra.ni => me'dra.ni
      • ka'ra.sa    => ka'ra.sa
Fixes
  • Options at the beginning or end of a structure properly check if they fill a syllable

0.20.0


BREAKING CHANGES
  • Group C now stands for [+cons, -syll], no longer just [-syll]
    • This is motivated in part so that C:[+syll] has the expected behaviour.
    • Note that as glides are [-cons], they are no longer covered under C. Use {C,G} or [-syll] (or after 0.20.1 -V) to capture both consonants and glides.

  • Glottalic consonants (e.g. h, ʔ) are now [+cons]

  • Rules such as a > e now preserve length
    • Previously, this rule would cause a word such as ha:t to become het.
    • This change now brings the behaviour of IPA Literals in line with Groups and Matrices.
    • Previous behaviour is preserved when the input is matched by length e.g. a:[+lng] > e which is equiv. to a:[+lng] > e:[-lng]
    • See here for an archived explanation for the previous behaviour.

New Features
  • Allow for multi-dimensional suprasegmentals (stress and length) to be referenced with one alpha.
    • [A long, B overlong] can be replaced with just [A length]
    • [A stress, B sec.str] can be replaced with just [A anystress]

  • Allow for the underline to be placed within an environment structure.
    • e.g. VN > [+nas] / <(..)_> instead of VN > [+nas] / _$ guarantees V and N are of the same syllable and N is coda.

  • Rework of Sets
    • Allow for multiple items in set choices
      • e.g. {i:[+long], u:[+long]} > {aj, aw}
      • These items can be mixed type e.g. {k<CV>, N$[-syll]}
    • Allow for sets, as a whole, to be modified by a matrix.
      • e.g. {i, u}:[+long] rather than {i:[+long], u:[+long]}

  • Rework of Metathesis logic
    • Ellipses act to group elements on either side
      • e.g. pf..s > & to result in pfas => safp whereas it currently would render pfas => sfap
      • In general: abcd..ef..ghi => ihg..fe..dcba
    • New @ metathesis operator which allows for maintaining grouped element orderings
      • e.g. pf..s > @ to result in pfas => sapf
      • In general: abcd..ef..ghi => ghi..ef..abcd

  • Added aliases J and W for ʝ and ɯ respectively
Fixes
  • ʁ̞ is correctly encoded as [+cons]
  • (Metathesis) Swapping segments of different lengths in the same syllable works as expected
  • Corrected structure location error highlighting
  • Removed redundant error locations from error messages

  • Increased Stability
    • Attempt to detect hanging rules and provide error to user
    • Rules such as $ > a$ no longer hang
    • Insertion rules with optionals that match zero times should no longer hang

  • Potential matches with ellipsis input are not skipped if a previous match has the wrong environment
    • e.g. k..h > & | #_ results in ka.ko.he => ka.ho.ke rather than previous ka.ko.he => ka.ko.he
