Graphics, Figures & Tables ⇒ How to display auto-formatted code in document?

[DryRun]

Hello,

I am new to using LaTeX and i have seen this LaTeX document with this format for C/C++ code. It's mostly just Arduino code and i want to know how can i do the same to display my code with numbered lines and this special font and colour based on code tags? Any ideas?

Often used packages are listings and minted.

Thank you for the suggestion. I am now using the 'minted' package and i have several pieces of codes in my LaTeX document. Now, i want to have a list of all the pieces of codes listed in my document and show it in the table of contents such that when i click on the title, it takes me to that section, just like for a chapter. So, i am using the command

Code: Select all

\listoflistings

to show the list of codes used throughout my entire document. But there are 2 problems that i'm trying to fix:
1. it comes up with a fixed title: "List of Listings"
2. it shows the list of codes on a separate page.

I found this method of changing the title to something else:

Code: Select all

\renewcommand\listoflistingscaption{List of source codes}
\listoflistings

And this changes the title of the listings but still, the problem of having it all automatically on its own separate page persists. How to fix that?

I created a new .tex file and put this code in it:

Code: Select all

\chapter*{List of source codes}\label{ch:listofsourcecodes}
\addcontentsline{toc}{chapter}{List of Source Codes}
\renewcommand\listoflistingscaption{List of Source Codes}
\listoflistings

This gives the effect that i want but it creates a blank page with the chapter title, followed by another page with the same title and the list of codes.

I also have another problem/question:

At the bottom of each code snippet that i included in my LaTeX document, there is a "Listing 1:", "Listing 2:", etc and i want to change this or remove it, if possible? I can only add a caption to it, but i would like to change it to "Source code" instead of "Listing". Also, how to make the numbers match the chapter/section instead of currently just incrementing integers?

Code: Select all

The next code will be directly imported from a file:

%Importing code from file

\inputminted{octave}{BitXorMatrix.m}

One-line code formatting also works with minted. For instance, a simple html sample like this:
\mint{html}|<h2>Something <b>here</b></h2>|can be properly 
formatted.
