A poster summarizing integrals across different dimensions, organized as a grid from left to right as 0d to 3d integrals, and different integrals on different function domains and codomains from top to bottom. The top row is about functions from R^1 to R, where "0D integral" is just evaluating the function, and the 1D integral is the simple single variable integral. The second row is about vector fields from R^2 to R^2, where the 1D integral is the work integral (line integral on tangent vector). The third row is about functions from R^2 to R. "0D integral" again is just evaluating the function. 1D integral is the line integral (on scalars), and 2D integral is the double/area integral. The fourth row is about functions from R^3 to R. "0D integral" is evaluating the function. The 1D integral here is still the line integral (on scalars). The 2D integral is the surface integral (on scalar). And the 3D integral is the triple/volumetric integral. The fifth row shows vector fields from R^3 to R^3, where the 1D integral is the work integral, and the 2D integral is the flux integral (surface integral on the normal vector). There are also extra red lines here showing the relationship of these integrals via the Stokes Theorem.

For instance, trying to match the pattern ^(a|ab)*c$ against the string abc results in an incorrect match, whereas simpler patterns seem to work perfectly fine. How can I be sure that the library is reliably handling these scenarios? It’s incredibly frustrating to deal with this inconsistency, and I expect a response and fix for this issue promptly. Can we get some rigorous debugging on this? It’s crucial for the integrity of the library that this functionality is solid. Users should not have to second guess the matching results based on regex complexity. If this is related to the underlying NFA implementation, it absolutely needs to be addressed right away – no exceptions. Please prioritize this fix as I need to know that I can rely on miniregex for any production-level projects. Waiting around for issues like this to be addressed is not feasible.
