Awk script to fix long lines within codeblocks

[Anon-Exploiter]

There are multiple closed issues for this within the repo: #21 & #23.

Running the following awk command before on the markdown and creating a sample out of it and then converting that to PDF should fix this. I'm breaking the lines at 90 characters.

Ran it on my notes from one of the challenge labs. You can also write ruby code for this but I wanted a solution which worked without having to do this manually atm.

awk '
BEGIN {
    in_code = 0;    # Flag for code block detection
    max_len = 90;   # Hard break at 90 chars
}
{
    # Toggle code block state
    if ($0 ~ /^```/) {
        in_code = !in_code;
        print $0;
        next;
    }

    if (in_code) {
        # For code blocks: brute-force split at max_len
        if (length($0) > max_len) {
            while (length($0) > max_len) {
                print substr($0, 1, max_len);
                $0 = substr($0, max_len + 1);
            }
            if ($0 != "") print $0;
        } else {
            print $0;
        }
    } else {
        # Outside code blocks: print as-is
        print $0;
    }

I added a mention of your script in the FAQ: 1c8ebef

I found this issue can be solved with fvset

Add this to the yaml config block:

header-includes:
  - \fvset{breaksymbol={}, breakanywheresymbolpre={}, breakanywhere, breaknonspaceingroup}

This will force line breaks and remove related newline symbols.

Nice, thanks !
