README
welcome to beautiful line output
A simple CLI application for testing ANSI color written in `C`.
This is an application that you can use on your Console/Terminal.
It provides you some simple + friendly + flexible options which you
can use easily. There is no prerequisite except **compile** it with a `C` compiler.
core features:
- support 3/4 bits : `ESC[Value;...;m`
- support 24 bits : `ESC[(38|48);2;...;m`
- code generation (= dump code) see the second screenshot

1. `git clone https://github.com/k-five/bline`
2. `cd bline/src/`
3. `make build`
usage (screenshot):
Then you have a binary file named: **bline** and you can put it in a valid path
that you have like: `/usr/bin/` or create your own path in `~/bin/` an put it
there. Or just use it in-place: `ls | ./bline -a red`

```
# all lines, foreground red:
ls | bline -a red
# all lines, foreground red, background green:
ls | bline -a red:green
# all lines, foreground is default (NOTE.3), background is green:
ls | bline -a :green
# add color-mode, odd lines (foreground) will be in light,italic,red
ls | bline -o light:red
# add text-mode, as well
ls | bline -o light:italic:cross:red
# combine options are okay:
ls | bline -a light:green -i red -I 7 -r yellow -R 5-10
# using hex value, foreground in red
df | bline -H -a ff00ff
# hex, foreground green, background red
df | bline -H -a 00ff00:ff0000
# hex just background
df | bline -H -a :ffff00
# look for string: 'sda' and make that/those line(s) green
lsblk | bline -m sda light:green

1. The app creates code dynamically. If you are interested in see: `ansi_code.h`
2. For non-HEX value it supports **color-mode** and **text-mode** and **foreground-color** and **background-color**.
3. But for HEX value it supports only **foreground-color** and **background-color**.
goal
This app have been designed mostly for educational purpose then colorizing some lines.
Although it looks like that, but I added a lot of comments so you can read the source
code easily. The two main goals in this app are:
1. how to use pointers and pointer arithmetic effectively
2. how to use heap effectively
3. how to use `bitwise` operators (see str2hex() function)
