The linphon Package

Getting started

Here's a quick example of importing linphon from the Typst Universe and using
it to set a phonological rule, namely a tapping rule as it may be found for
instance in General American English.

#import "@preview/linphon:0.1.0" as lp

#lp.rule(
  lp.fmat(
    ("-", "cont"),
    ("+", "cor"),
    ("-", "nas"),
  ),
  lp.fmat(
    ("+", "tap"),
  ),
  [
    #lp.fmat(
      ("+", "syll"),
      ("+", "stress"),
    )
    #lp.dash()
    #lp.fmat(
      ("+", "syll"),
      ("-", "stress"),
    )
  ]
)

The above will produce the following output:

Usage

The core functions of the linphon package are:

• linphon.fmat(..features: array | str) to set block-style feature matrices. The
  passed arguments may be valued feature pairs (passed as an array
  (value, feature), e.g. ("+", "syllabic)), privative features (passed as a
  valueless array, e.g. ("nasal",)), general categorial labels (passed as a
  string, e.g. "V") as well as conditional sub-matrices which will be set
  in angled brackets within the feature matrix (passed as an array
  of arrays, e.g. (("+", "back"), ("+", "round"))).
  • linphon.fmat-inline(..features: array | str) to set the feature matrix inline
    with the text.
• linphon.rule(input: content, output: content[, context: content]) to set
  phonological rules, with an optionally specified context/environment.
• linphon.constraint(body: content) to set a phonological constraint preceded
  by an *asterisk.
• linphon.dash() to set a long dash/underscore, e.g. for the phonological
  context/environment specification of a rule or constraint.
  • lindphon.dash-horizon() to set the dash aligned horizontally to the text.
• linphon.cases(..cases: content) to set different cases/options in a
  phonological rule or constraint.
  • linphon.cases-left(..cases: content) to set the cases with only a
    left-hand brace.
  • linphon.cases-right(..cases: content) to set the cases with only a
    right-hand brace.

For an overview including different variants of the above functions and various usage examples,
consult The linphon Reference.

Other useful packages

If you want to set phonological features and rules, you probably also have a need for IPA symbols/transcription and numbered examples.

For IPA symbols/transcriptions, why not try TyIPA or ascii-ipa.

For numbered example environments, combine linphon with eggs (or the slightly older leipzig-glossing).
