satscalc logotype vector


A calculator to help with invoicing for Norwegian film crew members.

You put in the time you worked, and it produces a nice receipt that you can copy-paste.

Building from source

🐧 Linux and MacOS 🍎

You'll need gcc and make.

git clone https://github.com/SanJacobs/satscalc
cd satscalc

And if you want to install it, do:

sudo make install

🪟 Windows / cross-compilation ⚡

You'll need zig (Tested with 0.9.1) and make.

Using zig because MinGW/GCC can't supply .pdb files needed for debugging with RemedyBG, and clang on Windows is a pain. MSVC is even more of a pain.

git clone https://github.com/SanJacobs/satscalc
cd satscalc
make windows

Or make windows32 if you need a 32-bit binary.

State of development

It's basically in a usable state now.

Currently, the only ruleset implemented is the one for advertisement and short-term work. Others may be added in the future.

Code is not yet law, so the source of this ruleset is flawed, because it has never had to compile. It is full of would-be unlit code paths, undefined cases and strangenesses. On top of this, the interpreter is me, a flawed human being, and so there is no guarantee of correctness.

However, in my flawed human opinion, I think it is pretty much on the money.

Known issues

Any known issues should be solved in a way which would not anger producers nor crew. Which is an impossibility, but I try.

Descriptions here are a simplifications and does not fully encapsulate the solutions as implemented in the code. Before you complain about any solution, read the code.

The main known issue is that in practice, advertisement and short-term jobs don't usually have a defined "normal" workday, because they're by definition only a few days, often all with different crew call times. Yet, the ruleset bases multiple rules off of this variable (which, as mentioned, oft goes undefined). This means there is no implementation of "overtime" before the "normal" workday has started, because there is no normal. Overtime is assumed to come beyond 8 hours after the call time.

There is a separate host of rules for work where you're staying and sleeping on-location. These rules are not covered. Aside from the rule about pay on holidays, which strangely appears in this section, despite seeming to apply outside of cases where you sleep on-location.
