In the katex documentation<\/a>, there’s a macro option detailed. Example:<\/p>\n

katex.render(“c = \\\\pm\\\\sqrt{a^2 + b^2}\\\\in\\\\RR”, element, {
\n displayMode: true,
\n macros: {
\n “\\\\RR”: “\\\\mathbb{R}”
\n }
\n});<\/p>\n

Is is possible to set a default set of macros in WP-Katex, either for the page in question, or for all pages?<\/p>\n

With the Mathjax-Latex plugin this is possible using something like:<\/p>\n

Macros: {
\nifrac: [‘{#1}\/{#2}’, 2],
\nReal: [‘{\\\\textrm{Re}}’, 0],
\nlr: [‘{\\\\left(#1\\\\right)}’, 1],
\nbiglr: [‘{\\\\Bigl(#1\\\\Bigr)}’, 1],
\nBiglr: [‘{\\\\Biggl(#1\\\\Biggr)}’, 1],
\nsetlr: [‘{\\\\left\\\\{#1\\\\right\\\\}}’, 1],
\nevalbar: [‘{{\\\\left.{#1}\\\\right\\\\vert}_{#2}}’, 2],
\nevalrange: [‘{{\\\\left.{#1}\\\\right\\\\vert}_{#2}^{#3}}’, 3],
\nevalnobar: [‘{{#1}_{#2}}’, 2],
\nBa: [‘{\\\\mathbf{a}}’, 0],
\n…
\n},<\/p>\n
