Goals

[divergentdave]

Here are my long-ish term goals for the project.

Calculation

• [x] Evaluate results of formulas for each line, given values for input lines
• [x] Provide helper methods to create modified forms/sets of forms by replacing lines
• [ ] Verify formula correctness against IRS's business rules by entering ATS scenarios, exporting MeF files, and submitting to MeF ATS endpoint

Language Interop

• [ ] Generate Python code for calculations
• [x] Generate JS code for calculations
• [ ] Generate C code
• [ ] Generate R code?

Applications

• [x] Re-implement b-k/1040.js with this as a new backend
• [x] Sensitivity analysis: Given initial values for inputs, evaluate the discrete derivative of one line with respect to each of the inputs

Import/Export

• [ ] Export values to MeF XML files
• [ ] Adapt this script and extract input values from an FFFF session
• [ ] Import values of input lines from MeF XML (mainly for round-trip tests)

Calculation is now done, see #3 and #4.

The merge-subgraphs function takes any number of FormSubgraph objects and combines them, with lines from later subgraphs overriding previous lines. This, combined with make-form-subgraph, is sufficient to create a modified form or set of forms.

Sensitivity analysis is done as of divergentdave/tenforty.tools@140786dd94f83374dd4ea9c930af95d8465932ea
