[Tex/LaTex] Copying code to LaTeX without losing the formatting

code

I have some code of around 350 lines, and I need to paste it inside a LaTeX file without losing the formatting such as the extra spaces. What do I need to use to get this in LaTeX?

Best Answer

You can use the package \usepackage{listings} and put your code in the following way

\begin{lstlisting}
Put your code here.
\end{lstlisting}

For information, you can read the wikibook LaTeX/Source Code Listings at https://en.wikibooks.org/wiki/LaTeX/Source_Code_Listings

[Tex/LaTex] minted doesn’t escape LaTeX code inside python docstring

As others have pointed out, this is because minted only activates mathescape inside comments.

FWIW, the same is true for the t-vim module in ConTeXt. It is similar to the minted package for LaTeX, but uses vim instead of pygments for syntax highlighting.

t-vim provides an option to load an arbitrary vim file before the source code is parsed. So, it is possible to change the parser on the fly. For example, to identify docstrings as comments, you can use the vim file given in this thread in the vim mailing list.

\usemodule[vim]

\startvimrc[name=python-docstring]
syn match  pythonBlock      ":$" nextgroup=pythonDocString skipempty skipwhite
syn region pythonDocString  matchgroup=Normal start=+[uU]\='+ end=+'+ skip=+\\\\\|\\'+ contains=pythonEscape,@Spell contained
syn region pythonDocString  matchgroup=Normal start=+[uU]\="+ end=+"+ skip=+\\\\\|\\"+ contains=pythonEscape,@Spell contained
syn region pythonDocString  matchgroup=Normal start=+[uU]\="""+ end=+"""+ contains=pythonEscape,@Spell contained
syn region pythonDocString  matchgroup=Normal start=+[uU]\='''+ end=+'''+ contains=pythonEscape,@Spell contained
hi def link pythonDocString Comment
\stopvimrc

\definevimtyping[PYTHON][syntax=python, extras=python-docstring]

\starttext

\startPYTHON[escape=on]
def naive(a,x):
    """
    lorem ipsum....

    this code will be escaped (note no spaces)
    \math{a=\{a_0,a_1,a_2,a_3,\dots,a_n\}}

    """
    # this code will be escaped
    p = a[0] # \math{p=\sqrt{\frac{1}{3}}}
    y = x
    for ai in a[1:]:
        p = p + ai*y
        y = y*x

    return p
\stopPYTHON
\stoptext

which gives:

One difference in t-vim is that you need to use \math{...} (or \m{...}) to enable math mode rather than $...$ . As with minted and listings do not use spaces in math mode.

To do something similar in minted, you will need to change the python parser so that it identifies docstrings as comments.

[Tex/LaTex] How to typeset LaTeX code inside a Table environment

The syntax for \verb is

\verb<char><text><char>

where <char> should be a (non special) character not found in <text>. Most often | or + are used for <char>.

A verbatim environment doesn't make sense in a table cell belonging to a column declared as l, c or r, just like a quote environment doesn't make sense in the argument to \mbox.

If you have multiline verbatim to be used in a cell column, you need to use a p column, but with some adjustments.
