FizziQ’s Text Input module is a sophisticated component that allows users to enter and display rich text, with special support for mathematical formulas in LaTeX. This user guide will guide you through the various features available.

1. Standard text entry

The interface offers a text field where you can enter comments, observations or explanations.

The text is automatically formatted and displayed in a readable font.

In display mode, if no text is present, a “Write a comment” message is displayed.

2. Support for mathematical formulas (LaTeX)

Manually inserting formulas

You can insert mathematical formulas directly using LaTeX syntax, either using the $$formula$$ format or the [formula] format

Automatic conversion of formulas

The module has an automatic converter that detects and transforms simple mathematical expressions into LaTeX code.

For example, if you write [x_1^2], it will automatically be converted to $$x_{1}^{2}$$.

Types of expressions recognized automatically:

Indices: x_1 → $$x_{1}$$

Exponents: x^2 → $$x^{2}$$

Fractions: (a+b)/(c+d) → $$\frac{a+b}{c+d}$$

Square roots: sqrt(x) → $$\sqrt{x}$$

Greek letters: alpha, beta, etc. → $$\alpha$$, $$\beta$$, etc.

3. Formula Editor Interface

The formula editor offers an intuitive interface organized into tabs:

“Basic” tab

Fractions

Square root

Exhibitors

Clues

nth root

“Advanced” tab

Integrals

Are

Products

Boundaries

Matrices

Derivatives

Systems of equations

Vectors

“Symbols” tab

Complete collection of Greek symbols (lowercase and uppercase)

Alpha, Beta, Gamma, etc.

4. Display and Editing Modes

Display mode: displays text with correctly rendered LaTeX formulas

Edit mode: allows you to modify text and formulas

“Validate” button: saves the changes and returns to display mode

Support for PDF export: the module can adjust its display for PDF export

Conclusion

The text input module makes it easy to create scientific documents with complex mathematical formulas, making your observations and analyses more accurate and professional.
