g_lib.sh

A shell (bash- and zsh-compatible) library, largely for:

logging (with colours)
easier input (e.g. with defaults, single-keystroke, continuation, etc)

Put the file on your PATH and then use source g_lib.sh in your shell.

g_lib usage

source g_lib.sh
g_opts ...

See source for what options are available.
g_colr [ -r ] $colour "text"

Example: g_colr cyan "this is output in colour"

Output the text in colour - where colour is one of:
```
- `black`, `red`, `green`, `yellow`, `blue`, `magenta`, `cyan` or `white`
- uppercase versions of the above indicate the bold version - e.g. `BLACK` is grey
- `BOLD` turns on bold for the current colour
- `${foreground_colour}_on_${background_colour}` - e.g. `black_on_white`
```
If text already has embedded colours, then the -r flag can be used to re-apply colour after each embedded colour segment. e.g. g_colr -r cyan "cyan-before $(g_colr red "red-highlight") cyan-after"
yorn "Continue"

Ask a question and the single-keystroke answer (y, n) returns in $yorn
