            the part you look like is inside a huge tag

            you can get the whole section by using soup.find('sec-header') but you will need to parse the section manually, something like this works, but it's some dirty job :

            The alternative notation you tried is a two-step process that first creates a lambda function using prop('a') and then immediately invoking it with ...(stateLens). The prop() function only receives a key name 'a', but cannot determine the object it belongs to as it only has the string parameter 'a' to work with. So, in the type definitions of prop the type A will be resolved to never because it's not assigned and cannot be inferred.

            I didn't test this, but you probably can do the same by manually passing along the type like

            Functional Programming/Optic concept that takes a partial object and returns a "filled in" object using lenses and traversals?
            Asked 2020-Sep-08 at 23:31

            (Edit I'm using monocle-ts, but if it's not possible with monocle-ts (since the author even says it's just a partial port of the original Monocle for Scala) but if there is something in another optics package for any language, I'm open to porting those ideas to TypeScript.)

            Suppose I have a helper type Partial such that it represents a record that has some or all, but no non-members, of type A. (So if A = { foo: number, bar: string } then Partial = { foo?: number, bar?: string }) (Edit This is Typescript's built-in Partial utility type.)

            I begin with

            ...

            I think, what you might want is a Polymorphic Traversal or PTraversal.

            A Traversal says, "If I have a function A => A, I can use modify to obtain a function S => S that uses the original function to modify all of the As that appear in S".

            By comparison, a PTraversal says, "if I have a function A => B, I can use modify to obtain a function S => T", this converts all of the As in S to B, producing a T.

            Mnemonically, the type parameters of PTraversal are:

            • S the source of the PTraversal
            • T the "modified" source of the PTraversal
            • A the target of the PTraversal
            • B the "modified" target of the PTraversal

            PTraversals are useful, because they let you write things such as the following:

            How to get the sum out of my switch in Swift?
            Asked 2020-Apr-20 at 02:30

            Hi I'm stuck trying to solve this: class Classy, to represent how classy someone or something is. "Classy". If you add fancy-looking items, "classiness" increases!

            Create a method, addItem() in Classy that takes a string as input, adds it to the "items" array and updates the classiness total.

            Add another method, getClassiness() that returns the "classiness" value based on the items.

            The following items have classiness points associated with them:

            1. "tophat" = 2
            2. "bowtie" = 4
            3. "monocle" = 5

            Everything else has 0 points.

            The sum is not performing correctly. The first problem is when it falls in te default case, everything is 0, I've tried in the default with:

            Asked 2020-Feb-12 at 16:47

            I have managed to generate pseudotime vs gene expression plots in Monocle for individual markers using the following code:

            ANSWER

            Answered 2020-Feb-12 at 16:47

            You can access the Pseudotime and "expectation" values that comprise the curve in plot$data (monocle just plots Pseudotime against spline-smoothed mean expression for the specified genes).

            You can then use approxfun to do 2d interpolation and evaluate a grid of points along the range of pseudotime.

            NOTE: I am not sure this is a sensible thing to do. Pseudotime is a fairly loose and wooly thing, and reading deeply into minute changes in pseudotime is likely to lead to pretty shaky conclusions.

            In any case, if you're interested in using this type of approach I would just read the code on github as it should be fairly easy to reproduce the output.
