Package goinsu on DUB

To use this package, run the following command in your project's root directory:

goinsu

goinsu - a simple su which doesn't mess with TTY and other stuff. It is as simple as "Hey, run this program as this user".

Why?

$ docker run -it --rm ubuntu:trusty su -c "ps aux"
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
root         1  7.0  0.0  46644  2628 pts/0    Ss+  19:07   0:00 su -c ps aux
root         7  0.0  0.0  15584  2100 ?        Rs   19:07   0:00 ps aux
$ docker run -it --rm ubuntu:trusty sudo ps aux

Why reinvent gosu?

goinsu does the same thing but in 10KB (well, 50KB if compiled as a static executable) instead of 1.8MB.

Why reinvent su-exec?

goinsu is written in the D programming language, which is a high-level programming language with metaprogramming, CTFE, and other cool things you can't find in C.

betterC?

Yep. goinsu written in a subset of the D programming language, called betterC. Just google for it, ya' know.

Alternatives

You can use gosu or su-exec, but they aren't as cool as goinsu.
