[Fractions] The Espanso package `espanso-fractions` I use routinely, produces the eighteen single character expansions of small fractions. I thought I'd play with a solution for longer fractions using super- and sub-script characters, and came up with the following, which can be triggered by e.g. `:1234/4567 `. #espanso #python #html

fractions.yml

  - regex: :(?P<before>\d+)/(?P<after>\d+)(?P<end>\s)
    replace: "{{output}}{{end}}"
    vars:
      - name: output
        type: script
        params:
          args:
            - python
            - -c
            - |
              sup = str.maketrans("0123456789", "⁰¹²³⁴⁵⁶⁷⁸⁹")
              sub = str.maketrans("0123456789", "₀₁₂₃₄₅₆₇₈₉")
              print("{{before}}".translate(sup) + "/" + "{{after}}".translate(sub))

html_fractions.yml

# For expansion into an HTML environment, like Thunderbird, or Google Docs, 
# the following is simpler, avoids the need for a script, and produces a 
# nicer output:

  - regex: ;(?P<before>\d+)/(?P<after>\d+)(?P<end>\s)
    html: |
      <sup style="vertical-align: top; font-size: 0.6em;">{{before}}</sup>/
      <sub style="vertical-align: bottom; font-size: 0.6em;">{{after}}</sub>
      <span style="all: unset;">{{end}}</span>
