Title:

Generalized Label Formatting

Version:

0.3.5

Maintainer:

Tim Bergsma <bergsmat@gmail.com>

Description:

The 'spork' syntax describes label formatting concisely, supporting mixed nesting of subscripts and superscripts to arbitrary depth. It intends to be easy to read and write in plain text, and easy to convert to equivalent presentations in 'plotmath', 'latex', and 'html'. Greek symbols and a multiplication symbol are explicitly supported. See ?as_spork and ?as_previews.

As of version 0.2.6,supported names of Greek letters are tokens (seegreek) possiblybounded by backticks (to be interpreted literally).

Convert HTML Greek entity references to XML

Description

Converts HTML Greek entity references to XML entity references.This is necessary because of a kableExtra bug: https://github.com/haozhu233/kableExtra/issues/814 .The mappings used here are from https://www.thoughtco.com/html-codes-greek-characters-4062212

Usage

Process Html Token

Description

Pre-processes a html token not recognized asspork. Escapes the common names for Greek lettersand escapes html metacharacters.

Usage

htmlToken(  x,  token_open = getOption("html_token_open", ""),  token_close = getOption("html_token_close", ""),  math_open = getOption("html_math_open", ""),  math_close = getOption("html_math_close", ""),  label_open = getOption("html_label_open", ""),  label_close = getOption("html_label_close", ""),  ...)

Arguments

x

character

token_open,token_close

these wrap the entire token (used once); by default the token is text-like

math_open,math_close

these wrap math-like portions of the token; the defaults try to give upright characters (non-italic) which may not work for Greek symbols

label_open,label_close

these re-wrap math-like portions of the token

...

ignored arguments

Value

html

Examples

htmlToken('foo')htmlToken('alpha')htmlToken('Alpha')

Process Latex Token

Description

Pre-processes a latex token not recognized asspork. Escapes the common names for Greek lettersand escapes latex metacharacters.

Arguments

x

character

token_open,token_close

these wrap the entire token (used once); by default the token is text-like

math_open,math_close

these wrap math-like portions of the token; the defaults try to give upright characters (non-italic) which may not work for Greek symbols

label_open,label_close

these re-wrap math-like portions of the token ifenforce_math is TRUE; defaults invoke traditional math mode

enforce_math

whether to enforce math mode for nested expression

...

Value

latex

Examples

latexToken('foo')latexToken('alpha')latexToken('Alpha')

Process Plotmath Token

Description

Processes a plotmath token. Escapes single-quotes and wraps in single-quotes.Also maps 'varepsilon' to 'epsilon', since plotmath has only the latter;likewise 'varrho' maps to 'rho' and 'varpi' maps to 'omega1'.

Usage

plotmathToken(  x,  conditional = getOption("plotmath_conditional_quote", FALSE),  unescape = getOption("plotmath_unescape", TRUE),  ...)

Arguments

x
