LuTex Documentation

Overview

LuTex allows you to write LaTeX-like input in a text editor and convert it into a downloadable PDF. It communicates with a backend API that processes your content and returns a generated PDF file.

How to Use

1. Type your content into the editor on the home page.
2. Click Download PDF.
3. Wait for the API to process your request.
4. The PDF will automatically download when ready.

Supported Features

• Basic LaTeX-style formatting
• Environment blocks (if supported by API)
• Console feedback for warnings and errors
• Note: LaTex syntax is also supported

Console Panel

The console on the right side of the editor displays system messages such as:

• Backend warnings
• Compilation messages
• Error responses

Troubleshooting

• Make sure your input is not empty before submitting.
• Check the console panel for backend error messages.
• If download fails, verify API availability.

Syntax

LuTex uses a lightweight custom syntax that compiles into LaTeX commands before generating a PDF. Most commands follow the format \command(text), and some shortcuts map directly to LaTeX equivalents.

Structure Commands

• \section(text) → Section
• \sub(text) → Subsection
• \subsub(text) → Subsubsection
• \p(text) → Paragraph
• \sp(text) → Subparagraph
• \heading(text) → Custom section heading (mapped internally)

Text Formatting

• \b(text) or \strong(text) → Bold
• \i(text) → Italic
• \u(text) → Underline
• \em(text) → Emphasis
• \code(text) or \tt(text) → Monospace / code

Text Size

• \small(text) → Small text
• \large(text) → Large text
• \huge(text) → Huge text

Lists

• \list(...) → Bullet list (itemize)
• \enumerate(...) → Numbered list
• List items use - item or -item syntax inside the block
• Single dash shortcut: - is also mapped to \item

Math Syntax Details

The \math(...) block is used for mathematical expressions. Inside the block, you can write standard LaTeX-style math expressions, but without the need for full LaTeX document syntax.

• Use standard math operators: +, -, *, /
• Fractions: \frac(a,b) → renders as a/b in LaTeX
• Exponents: a^2
• Subscripts: a_1
• Greek letters (if supported by backend): \alpha, \beta, \gamma

Examples

\math(
a = b + c
)

\math(
E = mc^2
)

\math(
\frac(a,b) = x^2 + y^2
)

\math(
\alpha + \beta = \gamma
)

\math(
\frac(1,2) + \frac(3,4)
)

Note: All expressions are parsed as a single math block. Multi-line alignment and advanced LaTeX environments (like align) may not be fully supported.

Environments

• \list → itemize environment
• \enumerate → enumerate environment
• \center → centered block

Example

\section(Welcome to LuTex)

\p(This is a lightweight markup system designed to make writing structured documents simple and readable.)

\heading(Why use LuTex?)

\list(
- Clean, minimal syntax
- Easy to parse
- Fast to write
- No boilerplate
)

\heading(Text Styling)

\p(You can emphasize text using simple commands:)

\b(Bold text shows importance)
\strong(Strong text highlights critical information)
\large(Large text stands out for titles or key ideas)

\heading(Code Example)

\code(
function greet(name) {
    console.log("Hello, " + name);
}
)

\heading(Math Support)

\math(
E = mc^2
)

\p(Inline expressions like a = b + c can be used for simple formulas.)

\heading(Layout Control)

\center(This text is centered for emphasis)

\p(That's it — simple, readable, and structured.)

Notes

• All commands use parentheses instead of LaTeX braces.
• Most commands are wrappers around LaTeX equivalents.
• Parser is regex-based — avoid deeply nested structures.
• Some features (like math and environments) depend on backend support.
