# Installation

## Prerequisites

Jupyter-TikZ is a Python (3.10+) and IPython Magics library. However, in order for Jupyter-TikZ to work properly, some non-Python dependencies need to be installed first:

- LaTeX
- Poppler

### LaTeX

LaTeX must be installed using one of the following distributions:

- [TeX Live](https://tug.org/texlive/) (All Platforms)
- [MikTeX](https://miktex.org/) (Windows)
- [MacTeX](https://www.tug.org/mactex/) (Mac)

You can test if a LaTeX distribution is installed by using the following command:

```latex
pdflatex --version
```

### Poppler

This application requires Poppler's `pdftocairo`. You must install it beforehand.

#### Conda - Platform Independent

```shell
conda install -c conda-forge poppler
```

#### Windows

Download Poppler for Windows [here](https://github.com/oschwartz10612/poppler-windows/releases/). You must add the `bin` folder to your [PATH](https://www.c-sharpcorner.com/article/how-to-addedit-path-environment-variable-in-windows-11/).

#### Linux

Most distributions come with `pdftocairo`. If it is not installed, refer to your package manager to install `poppler-utils`.

#### Mac

Install using `brew`:

```shell
brew install poppler
```

#### Checking the Installation

Finally, you can check if the `pdftocairo` utility is installed by using the following command in your terminal:

```shell
pdftocairo -v
```

#### Using custom pdftocairo path

Alternatively, if you are facing issues, you can configure the `pdftocairo` location (exclusive for use in `jupyter_tikz`) by setting the environment variable `JUPYTER_TIKZ_PDFTOCAIROPATH`:

```python
import os
custom_pdftocairo_path = os.path.join(
  os.getenv("LOCALAPPDATA"), "Poppler", "Library", "bin", "pdftocairo.exe"
)
os.environ["JUPYTER_TIKZ_PDFTOCAIROPATH"] = custom_pdftocairo_path
```

## Install Jupyter TikZ

You can install `jupyter-tikz` by using the following command in your terminal:

```shell
pip install jupyter-tikz
```

## Adding TikZ Syntax highlight

If you are using Jupyter Lab 4. You can add LaTeX highlight to `%%tikz` magic cells by using [JupyterLab-lsp](https://jupyterlab-lsp.readthedocs.io/en/latest/Installation.html) and editing [this part of the code in JupyterLab-lsp](https://github.com/jupyter-lsp/jupyterlab-lsp/blob/b159ae2736b26463d8cc8f0ef78f4b2ce9913370/packages/jupyterlab-lsp/src/transclusions/ipython/extractors.ts#L68-L74) in the file `extractor.ts`:

```ts
new RegExpForeignCodeExtractor({
  language: 'latex',
  pattern: '^%%(latex|tikz)( .*?)?\n([^]*)', // Add tikz support to this line
  foreignCaptureGroups: [3],
  isStandalone: false,
  fileExtension: 'tex'
}),
```

Now, you will have LaTeX syntax code highlighting for `%%tikz` magic cells, as demonstrated below:

![Using Jupyter TikZ with LaTeX syntax highlight](https://jupyter-tikz.readthedocs.io/stable/assets/highlight_cell_tikz.png)

For more information refer to this [link](https://discourse.jupyter.org/t/getting-syntax-highlighting-to-work-for-custom-cell-magic/11734/9).

# Basic usage

To begin, load the `jupyter_tikz` extension:

```
%load_ext jupyter_tikz
```

Use it as cell magic, it executes the TeX/TikZ code within the cell:

```latex
%%tikz
\begin{tikzpicture}
    \draw[help lines] grid (5, 5);
    \draw[fill=black!10] (1, 1) rectangle (2, 2);
    \draw[fill=black!10] (2, 1) rectangle (3, 2);
    \draw[fill=black!10] (3, 1) rectangle (4, 2);
    \draw[fill=black!10] (3, 2) rectangle (4, 3);
    \draw[fill=black!10] (2, 3) rectangle (3, 4);
\end{tikzpicture}
```
![Conway example](https://jupyter-tikz.readthedocs.io/stable/assets/conway.svg)

Or use it as line magic, where the TeX/TikZ code is passed as an IPython string variable:

```python
%tikz "$ipython_string_variable_with_code"
```

Additional options can be passed to the magic command:

```latex
%%tikz -i -t=pgfplots -nt -S=docs/assets/quadratic -r --dpi=150
\begin{axis}[
  xlabel=$x$,
  ylabel={$f(x) = x^2 + 4$}
]
    \addplot [red] {x^2 + 4};
\end{axis}
```
![Quadratic formula](https://jupyter-tikz.readthedocs.io/stable/assets/quadratic.png)

Going further, it is also possible to use it as a Python package:

```python
from jupyter_tikz import TexFragment

tikz_code = tex_template_code = r"""\begin{tikzpicture}
    \draw[help lines] grid (5, 5);
     \filldraw [color=orange, opacity=0.3] (2.5,2.5) circle (1.5);
\end{tikzpicture}"""

tikz = TexFragment(tikz_code)  # Create the tex template object

tikz.run_latex()  # Run LaTeX and shows the output
```

## v0.5.1

**🐞 Bug Fixes**

- Docs: Minor fix in changelog.

## v0.5.0

**🚨 Breaking Changes**

- Significant changes to Jinja2 rendering:
    - Replaced the default Jinja2 syntax with a custom one to avoid clashes with LaTeX braces (`{}`). Please refer to the documentation for more details.
    - With the new syntax, conflicts with LaTeX are significantly reduced, thus Jinja2 is now enabled by default and has become a mandatory dependency.
    - Added a `--no-jinja` flag to allow optional disabling of Jinja2 rendering.

## v0.4.2

**🐞 Bug Fixes**

- Doc: Fixed social cards image links.

## v0.4.1

**✨ Improvements**

- Switched temporary file names to MD5 hashing for deterministic hashes.

**🚀 Features**

- Doc: Support to social cards (Twitter and Facebook OG).

**🐞 Bug Fixes**

- Fixed indentation in `TexDocument.tikz_code`.
- Fixed docs issues.

## v0.4.0

**🚀 Features**

- Added support for PGFPlots with external data files.
- Introduced a new flag (`-k`) to retain LaTeX temporary files.
- Added support for grayscale output in rasterized mode.
- Introduced new flags `--save-tikz` and `--save-pdf` to save the TikZ and PDF files respectively; `--save-tex` now explicitly saves the full LaTeX document.

**🚨 Breaking Changes**

- Modified the save functionality: Options must now be passed in `TexDocument.run_latex(...)` as `TexDocument.save()` is no longer used.
- LaTeX rendering is now performed in the current folder, moving away from the use of a temporary directory (`tempdir`). This change facilitates access to external files for PGFPlots.

# Thanks

I had been using [ITikZ](https://github.com/jbn/itikz) for years. However, it doesn't update often and relies on the outdated `pdf2svg` for converting PDFs to images, which causes problems in Windows environments. Inspired by ITikZ and [IPython TikZ Magic](https://github.com/mkrphys/ipython-tikzmagic), I decided to create my own package, adding new features such as support for preambles, new Jinja syntax, and the ability to save the LaTeX result to IPython variables. I also switched from `pdf2svg` to Poppler, which works perfectly on all plataforms, including Windows.
