+# [MiTeX](https://github.com/mitex-rs/mitex)
+
+**[LaTeX](https://www.latex-project.org/) support for [Typst](https://typst.app/), powered by [Rust](https://www.rust-lang.org/) and [WASM](https://webassembly.org/).**
+
+[MiTeX](https://github.com/mitex-rs/mitex) processes LaTeX code into an abstract syntax tree (AST). Then it transforms the AST into Typst code and evaluates code into Typst content by `eval` function.
+
+MiTeX has been proved to be practical on a large project. It has already correctly converted 32.5k equations from [OI Wiki](https://github.com/OI-wiki/OI-wiki). Compared to [texmath](https://github.com/jgm/texmath), MiTeX has a better display effect and performance in that wiki project. It is also more easy to use, since importing MiTeX to Typst is just one line of code, while texmath is an external program.
+
+In addition, MiTeX is not only **SMALL** but also **FAST**! MiTeX has a size of just about 185 KB, comparing that texmath has a size of 17 MB. A not strict but intuitive comparison is shown below. To convert 32.5k equations from OI Wiki, texmath takes about 109s, while MiTeX WASM takes only 2.28s and MiTeX x86 takes merely 0.085s.
+
+Thanks to [@Myriad-Dreamin](https://github.com/Myriad-Dreamin), he completed the most complex development work: developing the parser for generating AST.
+
+## MiTeX as a Typst Package
+
+- Use `mitex-convert` to convert LaTeX code into Typst code in string.
+- Use `mi` to render an inline LaTeX equation in Typst.
+- Use `mitex(numbering: none, supplement: auto, ..)` or `mimath` to render a block LaTeX equation in Typst.
+- Use `mitext` to render a LaTeX text in Typst.
+
+PS: `#set math.equation(numbering: "(1)")` is also valid for MiTeX.
+
+Following is [a simple example](https://github.com/mitex-rs/mitex/blob/main/packages/mitex/examples/example.typ) of using MiTeX in Typst:
+
+```typst
+#import "@preview/mitex:0.2.6": *
+
+#assert.eq(mitex-convert("\alpha x"), "alpha  x ")
+
+Write inline equations like #mi("x") or #mi[y].
+
+Also block equations (this case is from #text(blue.lighten(20%), link("https://katex.org/")[katex.org])):
+
+#mitex(`
+  \newcommand{\f}[2]{#1f(#2)}
+  \f\relax{x} = \int_{-\infty}^\infty
+    \f\hat\xi\,e^{2 \pi i \xi x}
+    \,d\xi
+`)
+
+We also support text mode (in development):
+
+#mitext(`
+  \iftypst
+    #set math.equation(numbering: "(1)", supplement: "equation")
+  \fi
+
+  \section{Title}
+
+  A \textbf{strong} text, a \emph{emph} text and inline equation $x + y$.
+
+  Also block \eqref{eq:pythagoras}.
+
+  \begin{equation}
+    a^2 + b^2 = c^2 \label{eq:pythagoras}
+  \end{equation}
+`)
+```
+
+![example](examples/example.png)
+
+## MiTeX as a CLI Tool
+
+### Installation
+
+Install latest nightly version by `cargo install --git https://github.com/mitex-rs/mitex mitex-cli`.
+
+### Usage
+
+```bash
+mitex compile main.tex
+# or (same as above)
+mitex compile main.tex mitex.typ
+```
+
+## MiTeX as a Web App
+
+### MiTeX Online Math Converter
+
+We can convert LaTeX equations to Typst equations in web by wasm. https://mitex-rs.github.io/mitex/
+
+### Underleaf
+
+We made a proof of concept online tex editor to show our conversion speed in text mode. The PoC loads files from a git repository and then runs typst compile in browser. As you see, each keystroking get response in preview quickly.
+
+https://mitex-rs.github.io/mitex/tools/underleaf.html
+
+https://github.com/mitex-rs/mitex/assets/34951714/0ce77a2c-0a7d-445f-b26d-e139f3038f83
+
+## Implemented Features
+
+- [x] User-defined TeX (macro) commands, such as `\newcommand{\mysym}{\alpha}`.
+- [x] LaTeX equations support.
+  - [x] Coloring commands (`\color{red} text`, `\textcolor{red}{text}`).
+  - [x] Support for various environments, such as aligned, matrix, cases.
+- [x] Basic text mode support, you can use it to write LaTeX drafts.
+  - [x] `\section`, `\textbf`, `\emph`.
+  - [x] Inline and block math equations.
+  - [x] `\ref`, `\eqref` and `\label`.
+  - [x] `itemize` and `enumerate` environments.
+
+## Features to Implement
+
+- [ ] Pass command specification to MiTeX plugin dynamically. With that you can define a typst function `let myop(it) = op(upright(it))` and then use it by `\myop{it}`.
+- [ ] Package support, which means that you can change set of commands by telling MiTeX to use a list of packages.
+- [ ] Better text mode support, such as figure, algorithm and description environments.
+
+To achieve the latter two goals, we need a well-structured architecture for the text mode, along with intricate work. Currently, we don't have very clear ideas yet. If you are willing to contribute by discussing in the issues or even submitting pull requests, your contribution is highly welcome.
+
+## Differences between MiTeX and other solutions
+
+MiTeX has different objectives compared to [texmath](https://github.com/jgm/texmath) (a.k.a. [pandoc](https://pandoc.org/)):
+
+- MiTeX focuses on rendering LaTeX content correctly within Typst, leveraging the powerful programming capabilities of WASM and typst to achieve results that are essentially consistent with LaTeX display.
+- texmath aims to be general-purpose converters and generate strings that are more human-readable.
+
+For example, MiTeX transforms `\frac{1}{2}_3` into `frac(1, 2)_3`, while texmath converts it into `1 / 2_3`. The latter's display is not entirely correct, whereas the former ensures consistency in display.
+
+Another example is that MiTeX transforms `(\frac{1}{2})` into `\(frac(1, 2)\)` instead of `(frac(1, 2))`, avoiding the use of automatic Left/Right to achieve consistency with LaTeX rendering.
+
+**Certainly, the greatest advantage is that you can directly write LaTeX content in Typst without the need for manual conversion!**
+
+## Submitting Issues
+
+If you find missing commands or bugs of MiTeX, please feel free to submit an issue [here](https://github.com/mitex-rs/mitex/issues).
+
+## Contributing to MiTeX
+
+Currently, MiTeX maintains following three parts of code:
+
+- A TeX parser library written in **Rust**, see [mitex-lexer](https://github.com/mitex-rs/mitex/tree/main/crates/mitex-lexer) and [mitex-parser](https://github.com/mitex-rs/mitex/tree/main/crates/mitex-parser).
+- A TeX to Typst converter library written in **Rust**, see [mitex](https://github.com/mitex-rs/mitex/tree/main/crates/mitex).
+- A list of TeX packages and comamnds written in **Typst**, which then used by the typst package, see [MiTeX Command Specification](https://github.com/mitex-rs/mitex/tree/main/packages/mitex/specs).
+
+For a translation process, for example, we have:
+
+```
+\frac{1}{2}
+
+===[parser]===> AST ===[converter]===>
+
+#eval("$frac(1, 2)$", scope: (frac: (num, den) => $(num)/(den)$))
+```
+
+You can use the `#mitex-convert()` function to get the Typst Code generated from LaTeX Code.
+
+### Add missing TeX commands
+
+Even if you don't know Rust at all, you can still add missing TeX commands to MiTeX by modifying [specification files](https://github.com/mitex-rs/mitex/tree/main/packages/mitex/specs), since they are written in typst! You can open an issue to acquire the commands you want to add, or you can edit the files and submit a pull request.
+
+In the future, we will provide the ability to customize TeX commands, which will make it easier for you to use the commands you create for yourself.
+
+### Develop the parser and the converter
+
+See [CONTRIBUTING.md](https://github.com/mitex-rs/mitex/blob/main/CONTRIBUTING.md).

+# MiTeX Command Specification
+
+This includes ways to define specs, which can be used to define everything in the existing standard packages [latex-std](./latex/standard.typ).
+
+Even if you don't know Rust at all, you can still add missing TeX commands to MiTeX by modifing [latex-std](./latex/standard.typ), since they are written in typst! You can open an issue to acquire the commands you want to add, or you can edit the files and submit a pull request.
+
+
+## Introduce
+
+For a translation process, for example, we have:
+
+```
+\frac{1}{2}
+
+===[parser]===> AST ===[converter]===>
+
+#eval("$frac(1, 2)$", scope: (frac: (num, den) => $(num)/(den)$))
+```
+
+You can use the `#mitex-convert()` function to get the Typst Code generated from LaTeX Code.
+
+To achieve this, we need to define four components for LaTeX commands:
+
+- `cmd`: The name of the LaTeX command. Since LaTeX commands all start with `\`, we remove the leading `\` and use the command name as the key in the dictionary.
+  - There is also the concept of environments, for example, `\begin{pmatrix} 1 & 2 \\ 3 & 4 \end{pmatrix}` is a matrix environment.
+- `args`: The argument pattern of the LaTeX command. For example:
+  - `\alpha` has no arguments;
+  - `\hat{x}` matches one argument on the right;
+  - `\frac{1}{2}` matches two arguments on the right;
+  - `\sqrt[3]{2}` includes optional arguments;
+  - `\sum\limits` has `limits` matching one argument on the left;
+  - `\displaystyle` greedily matches all arguments on the right;
+  - `x \over y` as an infix operator greedily matches all arguments on both sides.
+- `alias`: The alias of the LaTeX command in Typst.
+  - The alias can be an existing symbol or function, for example, `alpha` and `binom(n, k)`;
+  - It can also be a key in the `mitex-scope` for `eval`, for example, our self-defined `frac`.
+- `handle`: The value in the `mitex-scope`, which is our self-defined symbol or processing function.
+  - For example, the `frac` key corresponds to the value `(num, den) => $(num)/(den)$`.
+
+MiTeX would need them for converting your TeX commands into typst code.
+
+At the Typst level, we need `alias` and `handle`, which are then combined into the `mitex-scope` passed to the `eval` function as the `scope` parameter.
+
+In short, currently a command spec is a typst dict, with its keys are name of the tex command, and its values are opaque spec item, which contains necessary information for MiTeX.
+
+In [specification file for standard latex](./latex/standard.typ), It constructs and exports a such command spec.
+
+Next, we provides a bunch of convenient functions for constructing opaque spec items.
+
+
+## Reference
+
+### `define-sym`
+
+Define a normal symbol, as no-argument commands like `\alpha`.
+
+```typst
+#let define-sym(s, sym: none) = { .. }
+```
+
+**Arguments:**
+- s (str): Alias command for typst handler.
+  For example, alias `\prod` to typst's `product`.
+- sym (content): The specific content, as the value of alias in mitex-scope.
+  For example, there is no direct alias for \negthinspace symbol in typst,
+  but we can add `h(-(3/18) * 1em)` ourselves
+
+**Return:** A opaque spec item and a scope item (none for no scope item)
+
+
+### `define-greedy-cmd`
+
+Define a greedy command, like `\displaystyle`.
+
+```typst
+#let define-greedy-cmd(s, handle: none) = { .. }
+```
+
+**Arguments:**
+- s (str): Alias command for typst handler.
+  For example, alias `\displaystyle` to typst's `mitexdisplay`, as the key in mitex-scope.
+- handle (function): The handler function, as the value of alias in mitex-scope.
+  It receives a content argument as all greedy matches to the content
+  For example, we define `mitexdisplay` to `math.display`
+
+**Return:** A opaque spec item and a scope item (none for no scope item)
+
+
+### `define-infix-cmd`
+
+Define an infix command, like `\over`.
+
+```typst
+#let define-infix-cmd(s, handle: none) = { .. }
+```
+
+**Arguments:**
+- s (str): Alias command for typst handler.
+  For example, alias `\over` to typst's `frac`, as the key in mitex-scope.
+- handle (function): The handler function, as the value of alias in mitex-scope.
+  It receives two content arguments, as (prev, after) arguments.
+  For example, we define `\over` to `frac: (num, den) => $(num)/(den)$`
+
+**Return:** A opaque spec item and a scope item (none for no scope item)
+
+
+### `define-glob-cmd`
+
+Define a glob (Global Wildcard) match command with a specified pattern for matching args
+Kind of item to match:
+
+- Bracket/b: []
+- Parenthesis/p: ()
+- Term/t: any rest of terms, typically {} or single char
+
+```typst
+#let define-glob-cmd(pat, s, handle: none) = { .. }
+```
+
+**Arguments:**
+- pat (pattern): The pattern for glob-cmd
+  For example, `{,b}t` for `\sqrt` to support `\sqrt{2}` and `\sqrt[3]{2}`
+- s (str): Alias command for typst handler.
+  For example, alias `\sqrt` to typst's `mitexsqrt`, as the key in mitex-scope.
+- handle (function): The handler function, as the value of alias in mitex-scope.
+  It receives variable length arguments, for example `(2,)` or `([3], 2)` for sqrt.
+  Therefore you need to use `(.. arg) = > {..}` to receive them.
+
+**Return:** A opaque spec item and a scope item (none for no scope item)
+
+
+### `define-cmd`
+
+Define a command with a fixed number of arguments, like `\hat{x}` and `\frac{1}{2}`.
+
+```typst
+#let define-cmd(num, alias: none, handle: none) = { .. }
+```
+
+**Arguments:**
+- num (int): The number of arguments for the command.
+- alias (str): Alias command for typst handler.
+  For example, alias `\frac` to typst's `frac`, as the key in mitex-scope.
+- handle (function): The handler function, as the value of alias in mitex-scope.
+  It receives fixed number of arguments, for example `frac(1, 2)` for `\frac{1}{2}`.
+
+**Return:** A opaque spec item and a scope item (none for no scope item)
+
+
+### `define-env`
+
+Define an environment with a fixed number of arguments, like `\begin{array}{lr}`.
+
+```typst
+#let define-env(num, alias: none, handle: none) = { .. }
+```
+
+**Arguments:**
+- num (int): The number of arguments as environment options for the environment.
+- alias (str): Alias command for typst handler.
+  For example, alias `\begin{array}{lr}` to typst's `mitexarray`,
+  and alias `\begin{aligned}` to typst's `aligned`, as the key in mitex-scope.
+- kind (str): environment kind, it could be "is-math", "is-cases", "is-matrix",
+  "is-itemize", "is-enumerate"
+- handle (function): The handler function, as the value of alias in mitex-scope.
+  It receives fixed number of named arguments as environment options,
+  for example `array(arg0: ..)` or `array(arg0: .., arg1: ..)`.
+  And it receives variable length arguments as environment body,
+  Therefore you need to use `(.. arg) = > {..}` to receive them.
+
+**Return:** A opaque spec item and a scope item (none for no scope item)
+
+
+### `sym`
+
+Define a symbol without alias and without handler function, like \alpha => alpha
+
+```typst
+#let sym = ((kind: "sym"), none)
+```
+
+**Return:** A opaque spec item and no scope item (none for no scope item)
+
+
+### `of-sym`
+
+```typst
+#let of-sym(handle) = ((kind: "sym"), (handle: handle))
+```
+
+Define a symbol without alias and with handler function,
+like \negthinspace => h(-(3/18) * 1em)
+
+**Arguments:**
+
+- handle (function): The handler function, as the value of alias in mitex-scope.
+  For example, define `negthinspace` to handle `h(-(3/18) * 1em)` in mitex-scope
+
+**Return:** A symbol spec and a scope item
+
+
+### `left1-op`
+
+Define a left1-op command without handler, like `\limits` for `\sum\limits`
+
+```typst
+#let left1-op(alias) = ((kind: "cmd", args: ( kind: "left1" ), alias: alias), none)
+```
+
+**Arguments:**
+
+- alias (str): Alias command for typst handler.
+  For example, alias `\limits` to typst's `limits`
+  and alias `\nolimits` to typst's `scripts`
+
+**Return:** A cmd spec and no scope item (none for no scope item)
+
+
+### `cmd1`
+
+Define a cmd1 command like \hat{x} => hat(x)
+
+```typst
+#let cmd1 = ((kind: "cmd1"), none)
+```
+
+**Return:** A cmd1 spec and a scope item (none for no scope item)
+
+
+### `cmd2`
+
