# Texments/minted not working - Undefined control sequence

I'm trying to add some syntax highlighting to my code and found two packages: texments and minted. I tried to use them, but I'm getting errors while trying to build. I used following code to test both packages:

\pygment{python}{ print "Hello World!"}


All what I get is errors:

**! Undefined control sequence.**

<argument> \PY
{k}{print} \PY {l+s}{"}\PY {l+s}{Hello World!}\PY {l+s}{"}
l.2 ...PY{l+s}{"}\PY{l+s}{Hello World!}\PY{l+s}{"}
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., \hobx'), type I' and the correct
spelling (e.g., I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

I have pygments installed, version 1.4.

How can I get everything to work?

Hi, welcome to tex.sx. Please format error messages as code blocks. They are easier to read this way. –  Martin Scharrer Feb 25 '11 at 10:14

This is an easy error to correct. You are not using the correct syntax. Pygments is the program that minted calls. The command (or environment) is \minted for a piece of code :

\begin{minted}{python}
def f(x) :
y = x**2
return y

for x in range(0,10) :
print f(x)*" " + "Hello World"
\end{minted}


For a one-line piece of code, the command is \mint. For example, \mint{python}|print "Hello World"| Note the delimiter | : the \mint command works like the \verb command, any symbol (not appearing in your line of code) may be used.

Many more options are available. For example, there is a listing environment that puts everything in a floating box. You may also show the line numbers, change the colors, etc ...
