A bloody great command line mate created a TaskWarrior wrapper, VIT(https://github.com/scottkosty/vit).

I think this wrapper is tmux friendly.
Also I like this approach to improve TaskWarrior because if you are already using TaskWarrior, there is no transfer cost.

How to install

$ git clone https://github.com/scottkosty/vit.git
$ cd vit
$ ./configure
$ make
$ make install

VIT was created with perl. I had to install perl modules because my linux system is not familiar with perl.

Trouble shooting

1. the curse of perl

If you receive this error message from ./configure

configure: error: can not continue: perl "Curses" module not found

Install libcurses-perl by https://community.linuxmint.com/software/view/libcurses-perl

2. when running vit

Can't locate Try/Tiny.pm in @INC (you may need to install the Try::Tiny module) (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.22.1 /usr/local/share/perl/5.22.1 /usr/lib/x86_64-linux-gnu/perl5/5.22 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.22 /usr/share/perl/5.22 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base .) at /usr/local/bin/vit line 13.
BEGIN failed--compilation aborted at /usr/local/bin/vit line 13.

Install Try::Tiny by https://ubuntu.pkgs.org/18.10/ubuntu-universe-amd64/libtry-tiny-smartcatch-perl_0.5-1_all.deb.html

If after installing it same error message occurs...

I attempted to find Tiny.pm in this directory

usr/share/perl5/vendor_perl/Try/Tiny.pm

According to this error message there is no perl path for usr/share/perl5/vendor_perl/

So,

export PERL5LIB=/usr/share/perl5/vendor_perl/

Then

it works!!
