Ignalia has announced an [intent to ship](https://www.igalia.com/2022/06/22/Intent-to-Ship-MathML.html) MathML in Chromium. In anticipation of that event, this version of Temml is written to support both Firefox and Chromium. - -Those two implementations are not written to the same specification. So Temml’s MathML must conform simultaneously to both [MathML 3]( https://www.w3.org/TR/MathML3/) (Firefox) and [MathML Core](https://w3c.github.io/mathml-core/) (Chromium). Given that challenge, I’m pretty happy with how well it has turned out. Temml emulates several hundred LaTeX functions and nearly all of them work very well. - -It’s not all perfect. In this version, Temml drops support for `\cancelto`, `\toggle`, `\texttip`, `\phase`, and `\longdiv`. I think that `\toggle` and `\texttip` are probably gone forever. The others I hope to restore someday after Chromium fully supports the `menclose` element. - -Also, Chromium’s implementation of MathML is new and not yet mature. It fails with some stretchy accents and extensible arrows. Chromium cannot yet print a page that contains MathML. I’m testing this in Chrome Canary and those issues may be worked out before MathML is shipped. - -### Added - -- Support for [MathML Core](https://w3c.github.io/mathml-core/) for rendering in Chromium - -### Removed - -- Support for `\cancelto`, `\toggle`, `\texttip`, `\phase`, and `\longdiv` - -## [0.6.9] = 2022-06-11 - -### Fixed - -- Colors of lower-case color names -- `\surd` vertical alignment when rendered in Latin Modern - -## [0.6.8] = 2022-05-20 - -### Fixed - -- Avoid crash when mhchem \ce{} is empty -- Numerals in text mode - -### Added - -- Support Unicode (sub|superscript) characters - -## [0.6.7] = 2022-03-27 - -### Fixed - -- Added operator spacing to Unicode characters ∖∘∙ -- Avoid error when a spacing function is the base of a subscript. -- Fix nested font size changes -- Replace string.substr() with string.slice() -- Use Unicode U+203E, Overline, for \bar{} - -### Added - -- Support \strictif and \strictfi - -### Docs - -- Explain how to work around a Cambria Math radical size problem -- Edit README for brevity - -## [0.6.6] = 2022-01-28 - -### Fixed - -- Workaround a Firefox bug.

The code for such a conversion -might look like this: - -Option 1: Macros do not persist between calls to Temml: - -``` -// Render all the math. -for (let aSpan of [...mathSpans]) { - const tex = aSpan.textContent; - const displayMode = aSpan.classList.contains("display"); - temml.render(tex, aSpan, { displayMode }); -} -// Optional postProcess to render \ref{} -temml.postProcess(document.body); -``` - -
Option 2: Macros defined with \gdef do persist: - -``` -// Optional macros object to hold macros that persist between calls to Temml. -const macros = {} -// Render all the math. -for (let aSpan of [...mathSpans]) { - const tex = aSpan.textContent; - const displayMode = aSpan.classList.contains("display"); - // Notice the macros argument below. - // It carries macros that were defined with \gdef or \global\let - temml.render(tex, aSpan, { macros, displayMode }); -} -// Optional postProcess to render \ref{} -temml.postProcess(document.body); -``` - -::: indented -Notice that you can choose when to stop macro persistence by redefining `macros`. -::: - -
- -
- -
Option 3: Macros persist and there are some predefined macros: - -Now say that you wish to pre-define two macros and a color with document-wide scope. - -``` -// Optional preamble to pre-define macros. -const macros = temml.definePreamble( - `\\newcommand\\d[0]{\\operatorname{d}\\!} - \\def\\foo{x^2} - \\definecolor{sortaGreen}{RGB}{128,128,0}` -); -// Render all the math. -for (let aSpan of [...mathSpans]) { - const tex = aSpan.textContent; - const displayMode = aSpan.classList.contains("display"); - temml.render(tex, aSpan, { macros, displayMode }); -} -// Optional postProcess to render \ref{} -temml.postProcess(document.body); -``` - -
- -Below, we examine the parts of that code. - -### In-Browser - -To render math in one DOM element, call `temml.render` with a TeX expression -and a DOM element to render into: - -```js -temml.render("c = \\pm\\sqrt{a^2 + b^2}", element); -``` - -If the element you provide is a `` element, Temml will populate it. -Otherwise, it will create a new `` element and make it a child -of the element you provide. - -### Server-Side - -To generate MathML on the server or to generate an MathML string of the -rendered math, you can use `temml.renderToString`: - -```js -const temml = require('./temml.cjs'); // if in Node.js -const mathML = temml.renderToString("c = \\pm\\sqrt{a^2 + b^2}"); -``` - -### Preamble - -To give document-wide scope to a set of macros or colors, define them in a preamble. - -```js -const macros = temml.definePreamble( - `\\newcommand\\d[0]{\\operatorname{d}\\!} - \\def\\foo{x^2} - \\definecolor{sortaGreen}{RGB}{128,128,0}` -); -``` - -Any valid [Temml macro](supported.html#macros) or [\definecolor](supported.html#style-color-size-and-font) -may be written into a preamble. Then include the resulting macros in the Temml options. - -### Options - -You can provide an object of options as the last argument to `temml.render` and `temml.renderToString`. For example: - -```js -temml.render( - "c = \\pm\\sqrt{a^2 + b^2}", - element, - { displayMode: true, macros } -); -``` - -Available options are: - -- `displayMode`: `boolean`. If `true` the math will be rendered in display mode, which will put the math in display style (so `\int` and `\sum` are large, for example), and will center the math on the page on its own line. If `false` the math will be rendered in inline mode. (default: `false`) - -- `macros`: `object`. A collection of custom macros. The easy way to create them is via a preamble, noted just above. Alternatively, you can provide a set of key-value pairs in which each key is a new Temml function name and each value is the expansion of the macro. Example: `macros: {"\\R": "\\mathbb{R}"}`. - -- `annotate`: `boolean`. If `true`, Temml will include an `` element that contains the input TeX string. (default: `false`) - -- `wrap`: (`"tex"` | `"="` | `"none"`). A mode for soft line breaks in non-display - mode math. The `tex` option sets a soft line break after every top-level relation and - binary operator, per _The TeXbook_, page 173. The `=` option sets a soft line - break before the second and subsequent top-level `=` signs. `tex` is the default. - - Caveats: Soft line breaks work in Chromium and Firefox, but do not work in WebKit or Safari. - Display mode math gets no soft line breaks. Annotated math gets no soft line - breaks. If a writer sets a hard line break via `\\` or `\cr`, then Temml will - not set any soft line breaks in that expression. - -- `leqno`: `boolean`. If `true`, display math has `\tag`s rendered on the left instead of the right, like `\usepackage[leqno]{amsmath}` in LaTeX. (default: `false`) - -- `colorIsTextColor`: `boolean`. In LaTeX, `\color` is a switch, but in early versions of MathJax and KaTeX, `\color` applied its color to a second argument, the way that LaTeX `\textcolor` works. Set option `colorIsTextColor` to `true` if you want `\color` to work like early MathJax or KaTeX. (default: `false`) - -- 'throwOnError': `boolean`. If true, Temml will throw parse errors to the console. If false, Temml will write the parse error to the output of the `render()` function. (default: false) - -- `errorColor`: `string`. A color string given in the format `"#XXX"` or `"#XXXXXX"`. This option determines the color that unsupported commands and invalid LaTeX are rendered in. (default: `#b22222`) - -- `maxSize`: `[number, number]`. This provides a way to cap all user-specified sizes, e.g. in `\rule{500em}{500em}`. The first number is the cap in `em` units, which will be applied to user-specified relative units. The second number is the cap in CSS `pt` units, which will be applied to user-specified absolute units. The default is `[Infinity, Infinity]`, which allows users to make elements and spaces arbitrarily large. - -- `maxExpand`: `number`. Limit the number of macro expansions to the specified number, to prevent e.g. infinite macro loops. (`\edef` expansion counts all expanded tokens.) If set to `Infinity`, the macro expander will try to fully expand as in LaTeX. (default: 1000) - -- `strict`: `boolean`. If `false` (similar to MathJax), allow features that make writing LaTeX convenient but are not actually supported by LaTeX. If `true` (LaTeX faithfulness mode), throw an error for any such transgressions. (default: `false`) - -- `xml`: `boolean`. If `true`, Temml will write a namespace into the `` element. That namespace is `xmlns="http://www.w3.org/1998/Math/MathML"`. Such a namespace is unnecessary for modern browsers but can be helpful for other user agents, such as Microsoft Word. (default: `false`) - -- `trust`: `boolean` or `function` (default: `false`). If `false` (do not trust input), prevent any commands like `\includegraphics` that could enable adverse behavior, rendering them instead in `errorColor`. If `true` (trust input), allow all such commands. Provide a custom function `handler(context)` to customize behavior depending on the context (command, arguments e.g. a URL, etc.). A list of possible contexts: - - - `{command: "\\url", url, protocol}`\ - where `protocol` is a lowercased string like `"http"` or `"https"` - that appears before a colon, or `"_relative"` for relative URLs. - - `{command: "\\href", url, protocol}` - - `{command: "\\includegraphics", url, protocol}` - - `{command: "\\class", class}` - - `{command: "\\id", id}` - - `{command: "\\style", style}` - - `{command: "\\data", attributes}` - - Here are some sample trust settings: - - - Forbid specific command: `trust: (context) => context.command !== '\\includegraphics'` - - Allow specific command: `trust: (context) => context.command === '\\url'` - - Allow multiple specific commands: `trust: (context) => ['\\url', '\\href'].includes(context.command)` - - Allow all commands with a specific protocol: `trust: (context) => context.protocol === 'http'` - - Allow all commands with specific protocols: `trust: (context) => ['http', 'https', '_relative'].includes(context.protocol)` - - Allow all commands but forbid specific protocol: `trust: (context) => context.protocol !== 'file'` - - Allow certain commands with specific protocols: `trust: (context) => ['\\url', '\\href'].includes(context.command) && ['http', 'https', '_relative'].includes(context.protocol)` - -## Post Process - -The `postProcess` function implements the AMS functions `\ref` and `\label`. -It should be called outside of any loop. - -The main Temml functions, `temml.render` and `temml.renderToString`, each -operate on only one element at a time. In contrast, the `postProcess` function -makes two passes through the entire document. If you choose not to support -`\ref`, `postProcess` can be omitted. - -If Temml is used server-side, `\ref` and `\label` are still implemented at -runtime with client-side JavaScript. A small file, `temmlPostProcess.js`, is -provided to be installed in place of `temml.min.js`. It exposes one function: - -``` -temml.postProcess(document.body) -``` - -If you do not provide a runtime `postProcess`, everything in Temml will work except `\ref`. - -If you use the [auto-render extension][], it includes the post-processor nuances. - -[auto-render extension]: https://github.com/ronkok/Temml/tree/main/contrib/auto-render - -# Fonts - -Temml has several different pre-written CSS files. You should use only one and -by that choice, you also choose a math font. There are several math fonts -available and each has different advantages. - -**Latin Modern** will provide the best quality rendering. It is a clone of -Computer Modern and so is very home-like for readers accustomed to LaTeX -documents. For best results, you must also serve a small -(10kb) `Temml.woff2` file. Then you’ll get support for `\mathscr{…}` and you’ll -get primes at the correct vertical alignment in Chrome and Edge. - -**Temml-Local.css** is the light-weight option. It calls two fonts: _Cambria -Math_, which comes pre-installed in Windows, or _STIX TWO_, which comes -pre-installed in iOS and MacOS (as of Safari 16). It also needs to be augmented -with `Temml.woff2`. - -Sadly, this option has rendering issues. Chrome botches extensible arrows and it -will fail to stretch the `∫` symbol on Windows. Android does not currently -provide a font with a MATH table, so it has many problems. - -**Asana** and **Libertinus** have some of the same rendering problems as Cambria Math, -although Asana does contain its own roundhand glyphs. - -**Fira Math** is a sans-serif math font. - -Several other math fonts exist and you can try them out at Frédéric Wang’s -[Mathematical OpenType Fonts][]. - -Where to find font files: - -- Temml.woff2 can be downloaded with the latest Temml [release][]. -- STIXTwoMath-Regular.woff2 is located at the STIX [repository][STIX]. -- LibertinusMath-Regular.woff2 is located at the Libertinus [repository][Libertinus]. -- The other fonts can be downloaded at [Mathematical OpenType Fonts][]. - -[release]: https://github.com/ronkok/Temml/releases -[STIX]: https://github.com/stipub/stixfonts/blob/master/fonts/static_otf_woff2/STIXTwoMath-Regular.woff2 -[Libertinus]: https://github.com/alerque/libertinus -[Mathematical OpenType Fonts]: https://fred-wang.github.io/MathFonts/ - -If you want a different math font size, you can add a rule to your own page's -CSS, like this example: - -```css -math { font-size: 125%; } -``` - -# Equation numbering - -In order to place automatic equation numbering in certain AMS environments, -Temml contains these CSS rules: - -``` -.tml-eqn::before { - counter-increment: tmlEqnNo; - content: "(" counter(tmlEqnNo) ")"; -} -body { counter-reset: tmlEqnNo; } -``` - -You can overwrite the `content` rule to produce customized equation numbers. -For instance, if chapter three of your book is in its own html file, that file’s -`` could contain: - -``` - -``` - -Then the automatic equation numbering in that chapter would look like: (3.1) - -If your site does not render automatic numbering properly, check if your other -CSS has overwritten the Temml counter-reset. - -# Extensions - -More Temml functionality can be added via the following extensions: - -* [auto-render][]: Find and render all math in a running HTML page. -* [copy-tex][]: When users select and copy elements, copies their LaTeX source to the clipboard -* [mhchem][]: Write beautiful chemical equations easily. -* [physics][]: Implement much of the LaTeX `physics` package. -* [texvc][]: Support functions used in wikimedia. - -[auto-render]: https://github.com/ronkok/Temml/tree/main/contrib/auto-render -[copy-tex]: https://github.com/ronkok/Temml/tree/main/contrib/copy-tex -[mhchem]: https://github.com/ronkok/Temml/tree/main/contrib/mhchem -[physics]: https://github.com/ronkok/Temml/tree/main/contrib/texvc -[texvc]: https://github.com/ronkok/Temml/tree/main/contrib/texvc - -To install extensions for browser use, include the appropriate file from the -`contrib` folder of the Temml repository. Then reference the file in the -`` of the HTML page. As in this `mhchem` example: - -```html - - ... - - - - -``` - -The extension reference must come after the reference to `temml.min.js`. - -For server-side use, just use `temml.cjs` or `temml.mjs` instead of `temml.min.js`. -`temml.cjs` and `temml.mjs` both include `mhchem`, `physics`, and `texvc`. - -# Security - -Any HTML generated by Temml should be safe from ` - - - - - -

Foreword

- -

This page compares the MathML output from four TeX-to-MathML conversion libraries. You should use Firefox or Safari to view this page because they can render the MathML today. MathML will be viewable in Chrome and Edge soon.

- -

MathJax and KaTeX of course also render math in other formats. This comparison is limited to MathML.

- -

Versions used are: Temml 0.10.25, MathJax 2.7.5, KaTeX 0.13.9, and TeXZilla 1.0.2.0

There is a similar page, -with functions [sorted by type](supported.html). - -Some functions are provided by an extension and are listed as such. They will -be available only in pages that include the extension. - -If you know the shape of a character, but not its name, -[Detexify](http://detexify.kirelabs.org/classify.html) can help. - - -## Symbols - -| Function | Rendered | Source or Comment | Package | -|----------------|-------------|-------------------|-----------| -|\!|$n!$|`n!`|| -|\\\!|$a\!b$|`a\!b`|| -|#|$\def\bar#1{#1^2} \bar{y}$|`\def\bar#1{#1^2} \bar{y}`|| -|\\#|$\#$||| -|%||`%this is a comment`|| -|\\%|$\%$||| -|&|$\begin{matrix} a & b\\ c & d \end{matrix}$|`\begin{matrix}`

More about Unicode script… - -The Unicode range U+1D49C - U+1D4B5, Mathematical Script, has been ambiguous. -Some fonts put chancery glyphs ($\mathcal{ABC}$) at those code points and some -fonts use roundhand glyphs ($\mathscr{ABC}$). Temml’s default for code points -in this range is chancery, which matches the fonts Cambria Math and STIX TWO. -It also matches the TeX function `\mathcal{…}`. - -Per Unicode 14+, Temml will return a roundhand glyph if you append a `\ufe01` -to a character in the range $\text{𝒜-𝒵}$. - -

Moreover, they should contain a broad collection -of special characters (see "Draft Unicode Technical Report #25. -UNICODE SUPPORT FOR MATHEMATICS" by Barbara Beeton, Asmus Freytag, -and Murray Sargent III). In particular, math OTF fonts are expected -to contain the following scripts: a basic serif script (regular, bold, -italic and bold italic), a calligraphic script (regular and bold), -a double-struck script, a fraktur script (regular and bold), a sans-serif -script (regular, bold, oblique and bold oblique), and a monospaced script. - -The basic script is, obviously, Latin Modern. Some scripts, however, -are borrowed from other fonts (the current selection, however, may -be subject to change), belonging, however, to the "TeX circle": - - * the calligraphic and fraktur alphabets are excerpted from the renowned - Euler family (http://en.wikipedia.org/wiki/AMS_Euler); - - * the double struck script is excerpted from Alan Jeffrey's bbold font - (http://www.tug.org/texlive/Contents/live/texmf-dist/doc/latex/bbold/bbold.pdf) - - * the sans serif and monospaced alphabets are excerpted from - the Latin Modern Sans and Latin Modern Mono fonts - (http://www.gust.org.pl/projects/e-foundry/latin-modern); - sans serif bold Greek symbols (required by the already mentioned - "Unicode Technical Report #25") were prepared using D.E. Knuth's - font sources with some manual tuning - -The main math component, that is, the math extension, was programmed -from scratch, with an attempt to retain the visual compatiblility -with the original D.E. Knuth's fonts. In particular, all symbols -(with a few exceptions) appearing in the D.E. Knuth's "canonical" fonts -have the same width (rounded) as the corresponding Knuthian ones. - -Note that the members of all the mentioned alphabets, except -the main roman alphabet, should be considerd symbols, not letters; -symbols are not expected to occur in a text stream; instead, -they are expected to appear lonely, perhaps with some embellishments -like subscripts, superscripts, primes, dots above and below, etc. - -To produce the font, MetaType1 and the FontForge library were used: -the Type1 PostScript font containing all relevant characters was -generated with the MetaType1 engine, and the result was converted -into the OTF format with all the necessary data structures by -a Python script employing the FontForge library. - -Recent changes (ver. 1.958 --> ver. 1.959) comprised -mainly interline settings in OTF tables (HHEA and -OS/2) and the correction of unicode slots assigned to -the contour integrals (glyphs `clockwise contour -integral', u+2232, and `anticlockwise contour -integral', u+2233, used to have swapped slots). - - * * * - -The TeX Gyre Math Project was launched and is supported by -TeX USERS GROUPS (CS TUG, DANTE eV, GUST, NTG, TUG India, TUG, UK TUG). -Hearty thanks to the representatives of these groups and also -to all people who helped with their work, comments, ideas, -remarks, bug reports, objections, hints, consolations, etc. diff --git a/site/assets/STIXTwoMath-Regular.woff2 b/site/assets/STIXTwoMath-Regular.woff2 deleted file mode 100644 index 3b97c9c8..00000000 Binary files a/site/assets/STIXTwoMath-Regular.woff2 and /dev/null differ diff --git a/site/assets/Temml-Asana.css b/site/assets/Temml-Asana.css deleted file mode 100644 index 4d542692..00000000 --- a/site/assets/Temml-Asana.css +++ /dev/null @@ -1,143 +0,0 @@ -/* -Asana Math is released under the SIL Open Font License.

Browser Support

-

Temml works in browsers that support MathML. This includes Chrome, Edge, Firefox, and Safari. Temml will never work in Internet Explorer.

-

Installation

-

For use in the browser, you can download a zip file of Temml from the releases page of the Temml repository. For server-side use, you can obtain Temml via CLI commands npm install temml or yarn add temml.

-

The minimum browser installation needs the following files. The css file and font file must be in the same folder.

-

Overview

-

Say that you have an HTMLCollection of elements whose contents should be converted from TeX strings to math. The code for such a conversion might look like this:

-

Option 1: Macros do not persist between calls to Temml:

-
// Render all the math.
-for (let aSpan of [...mathSpans]) {
-    const tex = aSpan.textContent;
-    const displayMode = aSpan.classList.contains("display");
-    temml.render(tex, aSpan, { displayMode });
-}
-// Optional postProcess to render \ref{}
-temml.postProcess(document.body);
Option 2: Macros defined with \gdef do persist: -
// Optional macros object to hold macros that persist between calls to Temml.
-const macros = {}
-// Render all the math.
-for (let aSpan of [...mathSpans]) {
-    const tex = aSpan.textContent;
-    const displayMode = aSpan.classList.contains("display");
-    // Notice the macros argument below.
-    // It carries macros that were defined with \gdef or \global\let
-    temml.render(tex, aSpan, { macros, displayMode });
-}
-// Optional postProcess to render \ref{}
-temml.postProcess(document.body);

Notice that you can choose when to stop macro persistence by redefining macros.

-
-
-
Option 3: Macros persist and there are some predefined macros: -

Now say that you wish to pre-define two macros and a color with document-wide scope.

-
// Optional preamble to pre-define macros.
-const macros = temml.definePreamble(
-    `\\newcommand\\d[0]{\\operatorname{d}\\!}
-    \\def\\foo{x^2}
-    \\definecolor{sortaGreen}{RGB}{128,128,0}`
-);
-// Render all the math.
-for (let aSpan of [...mathSpans]) {
-    const tex = aSpan.textContent;
-    const displayMode = aSpan.classList.contains("display");
-    temml.render(tex, aSpan, { macros, displayMode });
-}
-// Optional postProcess to render \ref{}
-temml.postProcess(document.body);
-

Below, we examine the parts of that code.

-

In-Browser

-

To render math in one DOM element, call temml.render with a TeX expression and a DOM element to render into:

-
temml.render("c = \\pm\\sqrt{a^2 + b^2}", element);

If the element you provide is a <math> element, Temml will populate it. Otherwise, it will create a new <math> element and make it a child of the element you provide.

-

Server-Side

-

To generate MathML on the server or to generate an MathML string of the rendered math, you can use temml.renderToString:

-
const temml = require('./temml.cjs');  // if in Node.js
-const mathML = temml.renderToString("c = \\pm\\sqrt{a^2 + b^2}");

Preamble

-

To give document-wide scope to a set of macros or colors, define them in a preamble.

-
const macros = temml.definePreamble(
-    `\\newcommand\\d[0]{\\operatorname{d}\\!}
-    \\def\\foo{x^2}
-    \\definecolor{sortaGreen}{RGB}{128,128,0}`
-);

Any valid Temml macro or \definecolor may be written into a preamble. Then include the resulting macros in the Temml options.

-

Options

-

You can provide an object of options as the last argument to temml.render and temml.renderToString. For example:

-
temml.render(
-  "c = \\pm\\sqrt{a^2 + b^2}",
-  element, 
-  { displayMode: true,  macros }
-);

Available options are:

-

  • displayMode: boolean. If true the math will be rendered in display mode, which will put the math in display style (so \int and \sum are large, for example), and will center the math on the page on its own line. If false the math will be rendered in inline mode. (default: false)

    • -

  • macros: object. A collection of custom macros. The easy way to create them is via a preamble, noted just above. Alternatively, you can provide a set of key-value pairs in which each key is a new Temml function name and each value is the expansion of the macro. Example: macros: {"\\R": "\\mathbb{R}"}.

    • -

  • annotate: boolean. If true, Temml will include an <annotation> element that contains the input TeX string. (default: false)

    • -

  • wrap: ("tex" | "=" | "none"). A mode for soft line breaks in non-display mode math. The tex option sets a soft line break after every top-level relation and binary operator, per The TeXbook, page 173. The = option sets a soft line break before the second and subsequent top-level = signs. tex is the default.

    -

    Caveats: Soft line breaks work in Chromium and Firefox, but do not work in WebKit or Safari. Display mode math gets no soft line breaks. Annotated math gets no soft line breaks. If a writer sets a hard line break via \\ or \cr, then Temml will not set any soft line breaks in that expression.

    • -

  • leqno: boolean. If true, display math has \tags rendered on the left instead of the right, like \usepackage[leqno]{amsmath} in LaTeX. (default: false)

    • -

  • colorIsTextColor: boolean. In LaTeX, \color is a switch, but in early versions of MathJax and KaTeX, \color applied its color to a second argument, the way that LaTeX \textcolor works. Set option colorIsTextColor to true if you want \color to work like early MathJax or KaTeX. (default: false)

    • -

  • 'throwOnError': boolean. If true, Temml will throw parse errors to the console. If false, Temml will write the parse error to the output of the render() function. (default: false)

    • -

  • errorColor: string. A color string given in the format "#XXX" or "#XXXXXX". This option determines the color that unsupported commands and invalid LaTeX are rendered in. (default: #b22222)

    • -

  • maxSize: [number, number]. This provides a way to cap all user-specified sizes, e.g. in \rule{500em}{500em}. The first number is the cap in em units, which will be applied to user-specified relative units. The second number is the cap in CSS pt units, which will be applied to user-specified absolute units. The default is [Infinity, Infinity], which allows users to make elements and spaces arbitrarily large.

    • -

  • maxExpand: number. Limit the number of macro expansions to the specified number, to prevent e.g. infinite macro loops. (\edef expansion counts all expanded tokens.) If set to Infinity, the macro expander will try to fully expand as in LaTeX. (default: 1000)

    • -

  • strict: boolean. If false (similar to MathJax), allow features that make writing LaTeX convenient but are not actually supported by LaTeX. If true (LaTeX faithfulness mode), throw an error for any such transgressions. (default: false)

    • -

  • xml: boolean. If true, Temml will write a namespace into the <math> element. That namespace is xmlns="http://www.w3.org/1998/Math/MathML". Such a namespace is unnecessary for modern browsers but can be helpful for other user agents, such as Microsoft Word. (default: false)

    • -

  • trust: boolean or function (default: false). If false (do not trust input), prevent any commands like \includegraphics that could enable adverse behavior, rendering them instead in errorColor. If true (trust input), allow all such commands. Provide a custom function handler(context) to customize behavior depending on the context (command, arguments e.g. a URL, etc.). A list of possible contexts:

    -

    • {command: "\\url", url, protocol}
      where protocol is a lowercased string like "http" or "https" that appears before a colon, or "_relative" for relative URLs.

      • -

    • {command: "\\href", url, protocol}

      • -

    • {command: "\\includegraphics", url, protocol}

      • -

    • {command: "\\class", class}

      • -

    • {command: "\\id", id}

      • -

    • {command: "\\style", style}

      • -

    • {command: "\\data", attributes}

    -

    Here are some sample trust settings:

    -

    • Forbid specific command: trust: (context) => context.command !== '\\includegraphics'

      • -

    • Allow specific command: trust: (context) => context.command === '\\url'

      • -

    • Allow multiple specific commands: trust: (context) => ['\\url', '\\href'].includes(context.command)

      • -

    • Allow all commands with a specific protocol: trust: (context) => context.protocol === 'http'

      • -

    • Allow all commands with specific protocols: trust: (context) => ['http', 'https', '_relative'].includes(context.protocol)

      • -

    • Allow all commands but forbid specific protocol: trust: (context) => context.protocol !== 'file'

      • -

    • Allow certain commands with specific protocols: trust: (context) => ['\\url', '\\href'].includes(context.command) && ['http', 'https', '_relative'].includes(context.protocol)

-

Post Process

-

The postProcess function implements the AMS functions \ref and \label. It should be called outside of any loop.

-

The main Temml functions, temml.render and temml.renderToString, each operate on only one element at a time. In contrast, the postProcess function makes two passes through the entire document. If you choose not to support \ref, postProcess can be omitted.

-

If Temml is used server-side, \ref and \label are still implemented at runtime with client-side JavaScript. A small file, temmlPostProcess.js, is provided to be installed in place of temml.min.js. It exposes one function:

-
temml.postProcess(document.body)

If you do not provide a runtime postProcess, everything in Temml will work except \ref.

-

If you use the auto-render extension, it includes the post-processor nuances.

-

Fonts

-

Temml has several different pre-written CSS files. You should use only one and by that choice, you also choose a math font. There are several math fonts available and each has different advantages.

-

Latin Modern will provide the best quality rendering. It is a clone of Computer Modern and so is very home-like for readers accustomed to LaTeX documents. For best results, you must also serve a small (10kb) Temml.woff2 file. Then you’ll get support for \mathscr{…} and you’ll get primes at the correct vertical alignment in Chrome and Edge.

-

Temml-Local.css is the light-weight option. It calls two fonts: Cambria Math, which comes pre-installed in Windows, or STIX TWO, which comes pre-installed in iOS and MacOS (as of Safari 16). It also needs to be augmented with Temml.woff2.

-

Sadly, this option has rendering issues. Chrome botches extensible arrows and it will fail to stretch the ∫ symbol on Windows. Android does not currently provide a font with a MATH table, so it has many problems.

-

Asana and Libertinus have some of the same rendering problems as Cambria Math, although Asana does contain its own roundhand glyphs.

-

Fira Math is a sans-serif math font.

-

Several other math fonts exist and you can try them out at Frédéric Wang’s Mathematical OpenType Fonts.

-

Where to find font files:

- -

If you want a different math font size, you can add a rule to your own page's CSS, like this example:

-
math { font-size: 125%; }

Equation numbering

-

In order to place automatic equation numbering in certain AMS environments, Temml contains these CSS rules:

-
.tml-eqn::before {
-  counter-increment: tmlEqnNo;
-  content: "(" counter(tmlEqnNo) ")";
-}
-body { counter-reset: tmlEqnNo; }

You can overwrite the content rule to produce customized equation numbers. For instance, if chapter three of your book is in its own html file, that file’s <head> could contain:

-
<style>
-   .tml-eqn::before { content: "(3." counter(tmlEqnNo) ")"; }
-</style>

Then the automatic equation numbering in that chapter would look like: (3.1)

-

If your site does not render automatic numbering properly, check if your other CSS has overwritten the Temml counter-reset.

-

Extensions

-

More Temml functionality can be added via the following extensions:

-

  • auto-render: Find and render all math in a running HTML page.

    • -

  • copy-tex: When users select and copy <math> elements, copies their LaTeX source to the clipboard

    • -

  • mhchem: Write beautiful chemical equations easily.

    • -

  • physics: Implement much of the LaTeX physics package.

    • -

  • texvc: Support functions used in wikimedia.

-

To install extensions for browser use, include the appropriate file from the contrib folder of the Temml repository. Then reference the file in the <head> of the HTML page. As in this mhchem example:

-
  <head>
-    ...
-    <link rel="stylesheet" href="./Temml-Local.css">
-    <script src="./temml.min.js"></script>
-    <script src="./mhchem.min.js"></script>
-  </head>

The extension reference must come after the reference to temml.min.js.

-

For server-side use, just use temml.cjs or temml.mjs instead of temml.min.js. temml.cjs and temml.mjs both include mhchem, physics, and texvc.

-

Security

-

Any HTML generated by Temml should be safe from <script> or other code injection attacks.

-

A variety of options give finer control over the security of Temml with untrusted inputs; refer to Options for more details.

-

  • maxSize can prevent large width/height visual affronts.

    • -

  • maxExpand can prevent infinite macro loop attacks.

    • -

  • trust can allow certain commands that may load external resources or change HTML attributes and thus are not always safe (e.g., \includegraphics or \class)

-

Browser Issues

-

If you are deciding whether to render math in MathML, know that all the major browser engines now support MathML. If you want to revel in the sight of over a thousand LaTeX functions rendered well in MathML, head on over to the Temml function support page.

-

The rest of you, stay here. This section identifies functions that browsers render poorly.

Notes:

-

  1. There are several items that WebKit places correctly only after a page refresh, or sometimes only after a back-button navigation.

    2. -

  2. WebKit renders some accents too high even after a page refresh. Temml does some work to mitigate this. It’s not enough.+ accent height

    3. -

  3. Chromium does not stretch a Cambria Math ∫ in display mode. Latin Modern is okay.+ accent italic correction

    4. -

  4. Chromium and WebKit mis+ extensible accents

    5. -

  5. Chromium sets + extensible arrows

    6. -

  6. Because Chromium does not support + height of ‖ in {Vmatrix} environment <enclose>, Temml uses background images for \cancel. It may not print properly.

    7. -

  7. WebKit mis-locates tags and AMS automatic equation numbers because it ignores width: 100% on an <mtable>.

    8. -

  8. WebKit laps are broken.

    9. -

  9. Chromium and WebKit system font extensible arrows have notes placed too high. Some do not stretch in Cambria Math. Again, Latin Modern is okay.

    10. -

  10. WebKit fails to stretch most extensible arrows.

    11. -

  11. Firefox and WebKit sometimes select radicals that are too tall. (Root cause: They don’t cramp subscripts and superscripts.)

    12. -

  12. In very tall radicals, Chromium does not accurately match the vinculum to the surd.

    13. -

  13. Automatic linebreaking (non-display mode) works in Chromium and Firefox. Not in WebKit.

    14. -

  14. WebKit hides mhchem subscripts and superscripts.

-

Another issue if you are targeting mobile: Android has not provided a math system font. They are planning to add a MATH table to the Noto Sans font. I don’t think it has shipped.

Foreword

- -

This page compares the MathML output from four TeX-to-MathML conversion libraries. You should use Firefox or Safari to view this page because they can render the MathML today. MathML will be viewable in Chrome and Edge soon.

- -

MathJax and KaTeX of course also render math in other formats. This comparison is limited to MathML.

- -

Versions used are: Temml 0.10.25, MathJax 2.7.5, KaTeX 0.13.9, and TeXZilla 1.0.2.0

Support Table

-

Temml is a JavaScript library that converts TeX math-mode functions to MathML. This page provides an alphabetically sorted list of TeX functions that Temml supports and some functions that it does not support. There is a similar page, with functions sorted by type.

-

Some functions are provided by an extension and are listed as such. They will be available only in pages that include the extension.

-

If you know the shape of a character, but not its name, Detexify can help.

Supported Functions

-

Temml is a JavaScript library that converts TeX math-mode functions to MathML. This page lists the TeX functions it supports, sorted into logical groups.

-

There is a similar Support Table, sorted alphabetically, that lists both supported and some un-supported functions.

x+y2xbye

\tag*{bye} x+y^{2x}
-

Also some environments have automatic equation numbering.

-

A \label{…} may be placed anywhere and will create an HTML id matching the \label{…} argument. That argument may contain only the characters A-Za-z0-9_-.

-

On sites where Temml fields are updated dynamically, \ref{…} may not be supported. Other Temml functions update only the local field. \ref{…} must make two passes through the entire document. Some sites may choose not to do this.

-

Color

- - - - - - -
F=ma {\color{blue} F=ma}F=ma {\color[RGB]{255,0,255} F=ma}
F=ma \textcolor{blue}{F=ma}F=ma {\color[rgb]{1,0,1} F=ma}
F=ma \textcolor{#228B22}{F=ma}F=ma {\color[HTML]{ff00ff} F=ma}
A \colorbox{aqua}{A}\definecolor{sortaGreen}{RGB}{128,128,0}
F=ma {\color{sortaGreen} F=ma}
A \fcolorbox{red}{aqua}{A}
-

\definecolor functions can be included in a preamble. If so, their color definitions will have document-wide scope.

-

Color functions can all take an optional argument to set the color model, as in the xcolor package. (Exception: \definecolor’s model argument is required.) Temml supports color models HTML, RGB, and rgb.

-

If the color model is omitted, Temml color functions will accept:

-

  • #rrggbb, #rgb, or rrggbb.

    • -

  • A color name previously created by \definecolor.

    • -

  • Any of the standard HTML predefined color names.

    • -

  • Any color from the following xcolor table.

Other Temml Environments

- - - - - -
EnvironmentsHow they differ from those shown above
darray, dcases, drcases… apply displaystyle
matrix*, pmatrix*, bmatrix*
Bmatrix*, vmatrix*, Vmatrix*		… take an optional argument that sets column
alignment, as in \begin{matrix*}[r]
equation*, gather*
align*, alignat*		… have no automatic numbering.
gathered, aligned, alignedat… do not need to be in display mode.
… have no automatic numbering.
… must be inside math delimiters in
order to be rendered by the auto-render
extension.
-

Acceptable horizontal line separators are: \\ and \cr.

-

Temml supports \tag{…}, \notag, and \nonumber to modify equation numbering.

-

The {array} environment does not yet support \cline or \multicolumn.

-

HTML

-

The following "raw HTML" features are potentially dangerous for untrusted inputs, so they are disabled by default, and attempting to use them produces the command names in red (which you can configure via the errorColor option). To fully trust your LaTeX input, you need to pass an option of trust: true; you can also enable just some of the commands or for just some URLs via the trust option.

Math-mode Unicode (sub|super)script characters will render as if you had written regular characters in a subscript or superscript. For instance, A²⁺³ will render the same as A^{2+3}.

There are two methods that will render any Unicode charater:

-

  1. Use the \char function and the Unicode code in hex. For example \char"263a will render as ☺ .

    2. -

  2. Write the character inside \text{…}. For example, \text{☺} will render as ☺.

More about Unicode script… -

The Unicode range U+1D49C - U+1D4B5, Mathematical Script, has been ambiguous. Some fonts put chancery glyphs (𝒜ℬ𝒞) at those code points and some fonts use roundhand glyphs (𝒜ℬ𝒞). Temml’s default for code points in this range is chancery, which matches the fonts Cambria Math and STIX TWO. It also matches the TeX function \mathcal{…}.

-

Per Unicode 14+, Temml will return a roundhand glyph if you append a \ufe01 to a character in the range 𝒜-𝒵.

Line Breaks

-

Hard line breaks are \\ and \newline.

-

Temml inserts soft line breaks per TeXbook p. 173 if not in display mode and no hard line breaks are employed. They work in Chromium and Firefox, but not in Safari.

-

ab a \atop b

-

∑0<i<m0<j<n

\sum_{\substack{0<i<m\\0<j<n}}
-

LaTeX puts the second argument of \raisebox into text mode, but it can contain math if the math is nested within $…$ delimiters, as in \raisebox{0.25em}{$\frac a b$}

-

∑1≤i≤j≤nxij

\sum_{\mathclap{1\le i\le j\le n}} x_{ij}

Temml also supports \llap, \rlap, and \clap. They work only in text mode if the rendering options include strict: true.

Notes:

-

distance will accept any of the Temml units.

-

\kern, \mkern, \mskip, and \hskip accept unbraced distances, as in: \kern1em.

-

\mkern and \mskip will not work in text mode and both will write a console warning for any unit except mu.

-

\rule{}{distance} is valuable as a vertical strut.

-

To create macros with document-wide scope, use \gdef, \global\let, or define a preamble in one of the Temml rendering options. (Global macros may be disabled for security reasons.)

-

Macros accept up to nine arguments: #1, #2, etc.

-

Available functions include:
\char \mathchoice \TextOrMath \@ifstar \@ifnextchar \@firstoftwo \@secondoftwo \relax \expandafter \noexpand

-

@ is a valid character for commands, as if \makeatletter were in effect.

-

Temml has no \par, so \long is ignored.

The \textXX versions can stack font family, font weight, and font shape. So \textsf{\textbf{H}} will produce 𝗛. The other versions do not stack, e.g., \mathsf{\mathbf{H}} will produce 𝐇.

-

In cases where math fonts do not have a bold glyph, \pmb can simulate one. For example, \pmb{\vartheta} renders as : ϑ

The effect of script level and font size:

- - - - - - -
Unittextstyle
normal size		scriptscripthuge
em or ex
mu
others
-

em and ex are affected by font size changes such as \Large, but they are not affected by script level, so they will not change size in a fraction numerator or an exponent.

-

mu is affected by both script level and font size.

-

The other units are absolute and are not affected by either script level or font size.

Unicode has special code points for bold Greek sans-serif, but no code points for
regular-weight Greek sans-serif. I know of no servable math font that has glyphs
for regular-weight Greek sans-serif. Consequently, these bold Greek sans-serif
glyphs are the best approximation I can make to sans-serif Greek.

The next line tests the length of an extensible arrow. Since Firefox does not
support the minsize attribute, Temml has a workaround. The middle arrow
should be as long at the bar between C & D.

The next line tests the fix for Temml issue #21. Firefox would ordinarily omit
the dot on the i below. It's fixed by a Temml CSS rule, so it renders properly.

Two dashes in _getBond are wrapped in braces to suppress spacing. i.e., {-} - * 6.
