markline: markable line picker for stdin line input

Example:

printf "%s\n%s\n%s\n" alpha bravo charlie > example.txt
cat example.txt | markline

You should see each line with a a bullet character that you can edit, and the line text:

• alpha
• bravo
• charlie

Move up and down in the list by typing arrow keys.

Mark any line by typing any alphanumeric character. The character will replace the bullet.

Mark as many lines as you want, such as:

1 alpha
2 bravo
3 charlie

When you're done, type ENTER or ESC to finish.

The command outputs each line:

Example

Suppose you have a text file that is a list of tasks, one per line, and you want to mark each line with "x" meaning done, or "o" meaning "todo".

Then you can pipe the results to any other command, such as a filter, that you can use to show just the tasks that are done.

Run:

cat example.txt | markline | grep '^x'

Mark each line with "x" or "o" such as:

x alpha
o bravo
x charlie

Type ENTER or ESC to finish.

Output:

x alpha
x charlie

The purpose of this command is a simple marker, that is easy to use, and that work wells in on the command line such as within a pipe.

The purpose isn't intended to handle very long lines, or very long inputs.
