+# flask-tex
+
+`flask-tex` offers helper functions for using LaTeX from within a Flask
+app. `flask-tex` requires a local LaTeX installation and uses `pdflatex`
+by default.
+
+## Usage
+
+Import `flask_tex.render_to_pdf` and use it like `flask.render_template`
+in your view function.
+
+```python
+from flask import Flask
+from flask_tex import render_to_pdf
+
+
+app = Flask(__name__)
+
+
+@app.route("/")
+def return_pdf_response():
+    return render_to_pdf("tex_template.tex", foo="Hello World!")
+```
+
+Your template might look like this and should be located in place where `flask`
+can find it.
+
+```tex
+\documentclass{article}
+
+\title{Using \LaTeX{} with Flask}
+
+\begin{document}
+
+\maketitle
+
+{{ foo }}
+
+\end{document}
+```
+
+For lower level access to LaTeX, use `flask.run_tex`:
+
+```python
+from flask_tex import run_tex
+
+pdf = run_tex(source, command="pdflatex")
+```
+
+where `source` is a string containing a `tex` document and command is a string defining
+the LaTeX command to use for compiling the source. The default `command` is `pdflatex`, but
+you can supply others, e.g. `latexmk -pdf`. `pdf` is a bytes object containing the pdf file.
+
+`run_tex` runs LaTeX inside a temporary directory. Use `flask_tex.compile_tex`
+to circumvent this and run LaTeX in a directory of your choice:
+
+```python
+from flask_tex import compile_tex
+
+pdf = compile_tex(source, command="pdflatex", directory="/foo/bar/")
+```
