combinator | A curated list of combinators | Functional Programming library

It seems like that one part of the use declarations created that problem. In the documentation (somewhere in some paragraph way to low that I looked at it) it says: " Streaming / Complete Some of nom's modules have streaming or complete submodules. They hold different variants of the same combinators.

A streaming parser assumes that we might not have all of the input data. This can happen with some network protocol or large file parsers, where the input buffer can be full and need to be resized or refilled.

A complete parser assumes that we already have all of the input data. This will be the common case with small files that can be read entirely to memory. "

Therefore, the solution to my problem is to swap use nom::character::complete::{char, space1}; instead of nom::character::streaming::{char, space1}; (3rd loc without counting empty lines). That worked for me :)

You can only use declaration quasi quotes in top-level declarations unfortunately. From the documentation:

A quasiquote may appear in place of

• An expression
• A pattern
• A type
• A top-level declaration

Instead of using TH, you could consider using OverloadedStrings:

Consider the expression (define p M), where M is some expression and p is a variable.

Let's suppose we're evaluating this expression in environment E. Evaluating (define p M) should do two things:

1. It should evaluate M in environment E; let the result be x.
2. It should modify environment E so that p is bound to x.

So what should happen when we evaluate (define factorialA (almost-factorial factorialA)) in an environment E where factorialA is not already defined?

First, we try to evaluate (almost-factorial factorialA) in environment E. To do this, we first evaluate almost-factorial, which succeeds. We then evaluate factorialA, which fails because factorialA is not defined in environment E. Thus, the whole thing should be expected to fail.

On the other hand, if we try

Here is a nom-only approach (nom 6.1.2):

A hacky solution I came up with is this:

In this case, you might want to consider writing it pointed

There is a one-to-one correspondence between the combinations that you seek and k-tuples of bounded non-negative integers with a given target sum. For example,

AAB, when drawn from ABC consists of 2 A, 1 B and 0 C, so the correspondence is AAB <=> (2,1,0).

One strategy is to write a generator for such tuples and then decode it as it generates to get the output that you want:

Yes but to an extent. In this example I can rotate the second div in the html flow by hovering over the first div using ~.

In OCaml, you can bind to operators any behavior, e.g.,
