Document Classes ⇒ listings package and blank space

Dear All,

I'm using the listings package to insert some code in some my documents. An example of the tex code in below:

Code: Select all

Run LaTeX here

The strange behavior is that for all the code inside the double quotation mark (for example "lis r5") the final document is: "lis_r5" with a "space symbol" instead of a normal blank space (even if showspaces=false).
It has to be noticed that the space symbol appears only for the code inside the double quotation mark.

Do you know how to remove the space symbol and to show just a blank space?

Hi sarox,

there's a special option for space symbols in strings. The following code disables the mentioned behaviour:

Code: Select all

\lstset{showstringspaces=false}
