ansi colors are not defined in LaTeX output

[artemohanjanyan]

When converting to LaTeX in non-inline mode, ansi2html produces commands like \textcolor{ansi33}, although ansi* colors are not defined.

Maybe just use \textcolor[HTML]{aa5500} like in inline mode?

[dev-zero]

this can easily be fixed with something like this in the latex preamble:

\definecolor{ansi30}{HTML}{262626}
\definecolor{ansi31}{HTML}{D70000}
\definecolor{ansi32}{HTML}{5F8700}
\definecolor{ansi33}{HTML}{AF8700}
\definecolor{ansi34}{HTML}{0087FF}
\definecolor{ansi35}{HTML}{AF005F}
\definecolor{ansi36}{HTML}{00AFAF}
\definecolor{ansi37}{HTML}{E4E4E4}
\definecolor{ansi38}{HTML}{1C1C1C}
\definecolor{ansi39}{HTML}{D75F00}
\definecolor{ansi310}{HTML}{585858}
\definecolor{ansi311}{HTML}{626262}
\definecolor{ansi312}{HTML}{808080}
\definecolor{ansi313}{HTML}{5F5FAF}
\definecolor{ansi314}{HTML}{8A8A8A}
\definecolor{ansi315}{HTML}{FFFFD7}

generated with:

from ansi2html.style import SCHEME
sol = SCHEME['solarized']
for i, n in enumerate(sol):
    print("\\definecolor{ansi3%s}{HTML}{%s}" % (i, n.strip('#').upper()))

problematic is rather that ansi1 (and similar ones) is used as a \textcolor while it should be converted to a \textbf{...} instead. So, I ended up with things like: \textcolor{ansi1 ansi32}

which I fixed with the following sed in the meantime:

sed -i -e 's|textcolor{ansi1 \(ansi[0-9]*\)}\({[^}]*}\)|textbf{\\textcolor{\1}\2}|g' test.tex

More than two years passed, and the problem is still here.

Generating the \definecolor{...} with the above Python script works - however the resulting file is still not LaTeX'able:

! Package xcolor Error: Undefined color `ansi38-238'.

See the xcolor package documentation for explanation.

Here's the file in question:

// Closures, lambda functions
#![allow(dead_code)]
use std::iter::Iterator;

pub type Weird2 = dyn Iterator<Item = i32>;

pub fn gen_iter() -> impl Iterator<Item = i32> {
    (0..)
}

pub fn double_it(a: impl Iterator<Item = i32>) -> impl Iterator<Item = i32> {
    a.map(|v| v + v)
}

pub fn sum_up(a: impl Iterator<Item = i32>) -> i32 {
    let s = 0;
    a.fold(s, |v, s| v + s)
}

pub fn take_more() {}

Here's the generating command:

$ bat --paging=never --color=always --style=full file1.rs | ansi2html -f 12 -L --scheme=osx > t.tex

Here's the preamble manually added to t.tex:
