parens | highly flexible and embeddable LISP toolkit | Script Programming library

Locally, my project works without errors, but after I deployed the project on Heroku, the following error occurred:

Again, everything is fine locally. Here is eslintrc.json:

Assume I have a json structure like:

I have used git grep for years to search for fixed strings and haven't used it much for doing regular expression searches.

I have places in the code with non-localized strings. For example:

I have to simplify custom regex expressions parsed to a certain data type. With "simplify" I mean the following (emphasis mine):

Given the rules:

• lowercase letters match themselves, eg.: a matches a and nothing else
• parens enclosing only letters match their full sequence, eg.: (abc) matches abc and nothing else
• square brackets enclosing only letters match every letters inside, eg.: [abc] matches a and b and c and nothing else

The following are all valid:

• (a[bc]) matches ab and ac and nothing else
• [a(bc)] matches a and bc and nothing else
• (a(bc)) is the same as (abc) and matches abc and nothing else
• [a[bc]] is the same as [abc] and matches a and b and c and nothing else

Regexes can be simplified. For example [a[[bb]b[[b]]](c)(d)] is really just the same as [abcd] which matches a, b, c and d.

I have implemented a simple parser combinator in Haskell using attoparsec and the following destination data type:

I have a component that I want to show a graph with multiple line series representing price changes over the last 24 hours. I have an endpoint that sends this data and I use the code below to show it.

One of the issues comes from errors seeming to come from the library itself meaning the graph will not even show up. Errors from the console when I load the page.

Other times, the page will load for a second and then go white and drain enough CPU to cause a crash.

The few times that the graph actually shows up on screen, it does not show any lines until the lines 81-85 are uncommented which it then shows the lines but does not zoom in on them leaving a mess on the screen.

Any help would be much appreciated.

I'm trying to match, using regex, all commas(followed by a space): , that are outside any parentheses or square brackets, i.e. the comma should not be contained in the parentheses or square brackets.

The target string is A, An(hi, world[hello, (hi , world) world]); This, These. In this case, it should match the first comma and the last comma (the ones between A and An, this and these).

So I could split A, An(hi, world[hello, (hi , world) world]); This, These into A, An(hi, world[hello, (hi , world) world]); This and These, not leaving parens/brackets unbalanced as a result.

To that end, it seems hard to use regex alone. Is there any other approach to this problem?

The regex expression I'm using: , (?![^()\[\]]*[\)\]])

But this expression will match other extra two commas , (the second and the third) which shouldn't have been matched.

Though if it is matching against the following strings, it'll match the right comma (the first one respectively): A, An(hi, world) and A, An[hi, world]

But if the parenthesis and brackets contain each other, it'll be problems.

My eslint don't work, and I don't know why.

Here is my eslint file:

I have read this article, which illustrates how the __VA_OPT__ function macro can be used to recursively expand a macro. I would like to implement something similar, with the difference being that the macro is expanded in a nested context.

The input:

I'm trying to use Idris 2's Text.Parser library to parse a pre-tokenized byte stream. I wrote the following utility function in the style of Parsec's expression parser:
