QUESTION
I am currently setting up a boilerplate with React, Typescript, styled components, webpack etc. and I am getting an error when trying to run eslint:
Error: Must use import to load ES Module
Here is a more verbose version of the error:
...ANSWER
Answered 2022-Mar-15 at 16:08I think the problem is that you are trying to use the deprecated babel-eslint parser, last updated a year ago, which looks like it doesn't support ES6 modules. Updating to the latest parser seems to work, at least for simple linting.
So, do this:
- In package.json, update the line
"babel-eslint": "^10.0.2",
to"@babel/eslint-parser": "^7.5.4",
. This works with the code above but it may be better to use the latest version, which at the time of writing is 7.16.3. - Run
npm i
from a terminal/command prompt in the folder - In .eslintrc, update the parser line
"parser": "babel-eslint",
to"parser": "@babel/eslint-parser",
- In .eslintrc, add
"requireConfigFile": false,
to the parserOptions section (underneath"ecmaVersion": 8,
) (I needed this or babel was looking for config files I don't have) - Run the command to lint a file
Then, for me with just your two configuration files, the error goes away and I get appropriate linting errors.
QUESTION
Consider following code
...ANSWER
Answered 2022-Mar-03 at 21:14You are correct, this is due to match ergonomics. The first case should hopefully be self explanatory, but the second and third cases can be a bit counter-intuitive.
In the second case:
(x,)
is a non-reference pattern (see the second example in the RFC). Thet
tuple reference is dereferenced, andx
is bound as aref
as it also is a non-reference pattern. Note thatt.0
was a reference to begin with, thus resulting inx
being a double reference.(&y,)
is also a non-reference pattern. Thet
tuple is dereferenced again to a(&i32,)
. However,&y
is a reference pattern being matched to a&i32
reference. Hencey
is bound withmove
mode and is ani32
.
In the third case:
Using the same reasoning as the second case,
u
is dereferenced viaDeref
coercion to an(i32,)
, andx
, a non-reference pattern, is bound inref
mode. Hencex
is an&i32
.Again with the same reasoning as the second case,
u
is dereferenced to an(i32,)
. The&y
reference pattern is then matched to ani32
, a non-reference, which causes an error.
QUESTION
I have an array of positive integers. For example:
...ANSWER
Answered 2022-Feb-27 at 22:44This problem has a fun O(n) solution.
If you draw a graph of cumulative sum vs index, then:
The average value in the subarray between any two indexes is the slope of the line between those points on the graph.
The first highest-average-prefix will end at the point that makes the highest angle from 0. The next highest-average-prefix must then have a smaller average, and it will end at the point that makes the highest angle from the first ending. Continuing to the end of the array, we find that...
These segments of highest average are exactly the segments in the upper convex hull of the cumulative sum graph.
Find these segments using the monotone chain algorithm. Since the points are already sorted, it takes O(n) time.
QUESTION
I wrote some code in https://github.com/p6steve/raku-Physics-Measure that looks for a Measure type in each maths operation and hands off the work to non-standard methods that adjust Unit and Error aspects alongside returning the new value:
...ANSWER
Answered 2021-Dec-30 at 03:53There are a few ways to approach this but what I'd probably do – and a generally useful pattern – is to use a subset to create a slightly over-inclusive multi and then redispatch the case you shouldn't have included. For the example you provided, that might look a bit like:
QUESTION
I tried to replace a character a
by b
in a given large string. I did an experiment - first I replaced it in the whole string, then I replaced it only at its beginning.
ANSWER
Answered 2022-Jan-31 at 23:38The functions provided in the Python re
module do not optimize based on anchors. In particular, functions that try to apply a regex at every position - .search
, .sub
, .findall
etc. - will do so even when the regex can only possibly match at the beginning. I.e., even without multi-line mode specified, such that ^
can only match at the beginning of the string, the call is not re-routed internally. Thus:
