Ask aspell to skip part of document

I'm using aspell to spell check LaTeX documents on Linux. Very often my documents contain samples of code in various programming languages, and I would like aspell to simply skip those lines while spell checking.

Is there anything I can write in my document to turn aspell off on a section of text? Something like:

This line should be spell checked.

% Hey, aspell, don't check the following lines
\begin{lstlisting}
if (xyzzy > foobar) {
    doSomethingSilly();
}
\end{lstlisting}
% Hey, aspell, please check the following

This line should be spell checked.

Solution

aspell to skip part of document

spellcheck LaTeX documents

LaTeX documents require a little more work.

command

aspell --lang=en_GB --add-tex-command="mySkip op" -c teste.tex

put at start \mySkip[ after { again a \mySkip[

teste.tex

\documentclass{article} 

\makeatletter
\def\myComment{\@ifnextchar[{\@with}{\@without}}
\def\@with[#1]#2{Hello #1, have you met #2?}
\def\@without#1{Goodbye #1.}
\makeatother


\mySkip[
 if (xyzzy > foobar) {
\mySkip[
   doSomethingSilly();
   doSomethingOther();
   doSomethingExtra();
 }
]]
This liine should be spell checked.

Problem after every opening curly brace { in the code you need \mySkip[

\mySkip[
 if (abcdef > foobar) {
\mySkip[
   doSomethingSilly();
   if (test > 100) {
\mySkip[
     doSomethingOther();
   }
   doSomethingExtra();
 }
]]
This liine should be spell checked.

With a search and replace you can make the code ready

For sgml it's easier.

Step by step

create a folder aspell60-7
copy teste.html into.

teste.html

This line should be spell checked.

<nospell>
if (xyzzy > foobar) {
    doSomethingSilly();
}
</nospell>
<script>
if (xyzzy > foobar) {
    doSomethingSilly();
}
</script>

This line should be spell checked.

change a letter in teste.html
cd into folder aspell60-7

enter image description here

enter following command

aspell --lang=en_GB --add-filter=sgml --add-sgml-skip=nospell --add-sgml-skip=script -c -S teste.html

after run the command

enter image description here

after enter 1 for 1) line .
aspell terminates.
Gedit tells file teste.html was changed.
after new load
previously modified word liine is correct.
all lines surrounded by <nospell> and <script> are ignored.

this also works in windows, but only with aspell6.
