Option to change height (number of lines)

[qazip]

It would be awesome if we could change the height of hstr. I don't like having it full-terminal, I would like to see only, say, 10 lines.

@dvorka @qazip hi, You can change height with this patch

copy it in patch_file, save it in the src directory, then execute this commands from src directory

mv hstr.c hstr.c-orig
patch < parch_file

then rebuid hstr

Now you can add

export HSTR_CONFIG=max-height:10, hicolor

at your .bashrc

you can set the max-height value, here is 10

This code doesn't manage max and min value so be care to what you set.
