Custom environment for syntax highlighted and indented code














0















I am writing some lecture notes involving blocks of code. I would like a custom environment always indents the block with consistent formatting. My current attempt fails:



usepackagecolor
usepackagelistings

newenvironmentcode[1]%
beginlstlisting
setlengthleftmargin4em%
#1
endlstlisting


definecolorpbluergb0.13,0.13,1
definecolorpgreenrgb0,0.5,0
definecolorpredrgb0.9,0,0
definecolorpgreyrgb0.46,0.45,0.48

lstsetlanguage=Java,
showspaces=false,
showtabs=false,
breaklines=true,
showstringspaces=false,
breakatwhitespace=true,
commentstyle=colorpgreen,
keywordstyle=colorpblue,
stringstyle=colorpred,
basicstyle=ttfamily,
moredelim=[il][textcolorpgrey]$$,
moredelim=[is][textcolorpgrey]%%%%



When I try this in LaTeX, I get



begincode
if (int == 2) System.out.println("foo");
else System.out.println("bar");
endcode


I get the error message:

My listing environment on its own works fine (e.g. syntax highlighting works).
