x-pipe | Redis multi-data center replication management system | Pub Sub library

I have a Common Lisp reader macro to parse lazy/delayed declarations of an "or" relation, using infix syntax separated by pipe chacaters ("|") as well as standard list parentheses and keyword literals. Consider the form (:a :b|:c) -- it represents a 2 part tuple where the first element is certainly :a, the second element is either :b or :c. One can infer for instance that valid forms for the whole tuple are (:a :b) or (:a :c).

I have function-encapsulated logic already to destructure these tuple list forms subsequent to the read macro. But at read time I need to parse a form like :a|:b|:c and tag it with the pipes removed, like (:lazy-or :a :b :c). Use of infix syntax is purely for the reader-facing forms; infix forms are ephemeral and are discarded as soon as possible, immediately at the read stage, in favor of equivalent legal lisp forms tagged with :lazy-or.

So I made a read macro that is nearly working as I'd like it, but presently an extra pipe needs to be used before the first or-form keyword element as a sort of reader sigil (I'd like that to be not necessary at all), and it can't presently infer similar forms using either nested-parentheses or splice-notation as equivalent (like in arithmetic, 2+(3*4) being the same order-of-operations, an equivalent form, as 2+3*4).

The macro (derived from "slash reader" here: http://www.lispworks.com/documentation/HyperSpec/Body/f_rd_rd.htm):

I have a Go program that consumes "live" input from a shell pipe, eg:

I am trying to create a bash script which shows me the latest stats about corona infection numbers in the countries Germany and Switzerland and also in the whole world.

Is it possible to start an interactive shell program and inject something to its stdin, keep it running afterwards, and that in a single line?

I'd like to start electron -i (REPL mode) and execute .load index.js right away. It has no switch that accepts code to execute unlike many other REPLs.

Im getting like 50 errors that all say that angular/core/core has no exported member 'eeFactoryDef'.

They come from different node_modules, for example angular/cdk, ng-bootstrap, ngx-pipes, ng2-dragula and some more. I didn't find anything from google either.

I m trying to use the following pipe in my personal training project, going by the specs I have installed the library using npm and I can see it in the ng module folder

Then I tried to add the NgPipesModule in my app.module as below

I have a Javascript array of "Album" objects which holds data such as Album Title, Year, Artist, Description

Id like to create a new String Array that holds just the distinct years.

Ive tried a unique pipe from

https://www.npmjs.com/package/ng2-pipes#installation

But have no luck.

My goal is to have a "Filter by year" dropdown which takes a string array of unique years

So I'm trying to pipe two Node based js scripts together, which works as expected doing something like this.

How to pipe Node.js scripts together using the Unix | pipe (on the command line)?

essentially

$ ./a.js | ./b.js

The pipe works fine as long as the only thing output to the next script is valid JSON (for example). But I would like to see some debug logs in the first script (ideally without using the popular debug module). Funny enough, I know the debug module will do this without sending unwanted data to the pipe. How does it do that? I'd rather not dig into their code to see (lazy).

Seems like console.log, and console.error both use process.stdout/err so if I log something out, I end up mucking up the pipe.

Difference between "process.stdout.write" and "console.log" in node.js?

Is there a way to use a different tty socket or something? No idea where to start.

I'm using ngx-pipes from page:

https://www.npmjs.com/package/ngx-pipes#orderby

i'm using specifically the pipe orderBy, but when i use the orderBy pipe in my HTML, the information doesn't be ordered correctly (in order of minor to major).

I tried putting an extra property in the treated object, this property called diff is the result of the sum of (lat and lng) TREATED PROPERTIES, not the original

and using that property instead of using the lat and lng properties both, but doesn't works...
