DaveML

Adds color to linux files using simple markup.

For example, <WBB> for bold white text on a blue background. This becomes the ANSI color escape sequence: \x1b[37;44;1m.

Instead of this, you might want to try: bat, ccat, pygmentize, or highlight.

Example

Create a file demo.txt, such as:

<WBB>|             |
<WBB>|   Welcome   |
<WBB>|             |

<GXX>This is going to be <CXX>cool <RBX>!!!

And it will become:

Usage

daveml.sh demo.txt

cat demo.txt | daveml.sh

cat <<EOF | daveml.sh -p ""
Usage: <BBX>some-command <YBX>arg1 arg2
EOF

The current default is to show a | line prefix. It can be removed or changed with -p:

daveml.sh -p "" /etc/motd
daveml.sh -p ">> " /etc/motd

Codes

Colors are specified as 3 letter tags, such as RXX for red text, or WBB for bold white with a blue background. CLR is used to clear/reset.

<foreground> <bold or X> <background or X>

K = black, R = red, G = green, Y = yellow, B = blue M = magenta, C = cyan, W = white, X = default

Notes

• This does not currently include support for italic, _ underline _, or strikethrough.
• This uses perl, but could be modified to use sed instead.
• Remember, if you do a bold color before a non-bold, you'll need a CLR to remove the bold effect: <BBX>...<CLR><BXX>...
