javascript keyvalue object

Javascript convert key value string to Object

Let the following "key value string":

"maxRU=5000;database=rktmb_credit;counting=databaseLevel"

I want that string to be converted to Objet or JSON:

{ maxRU: '5000', database: 'rktmb_credit', counting: 'databaseLevel' }

Use Object.fromEntries()

A built-in tool that is Use Object.fromEntries() where it states that:
const arr = [ ['0', 'a'], ['1', 'b'], ['2', 'c'] ];
const obj = Object.fromEntries(arr);
console.log(obj); // { 0: "a", 1: "b", 2: "c" }

So, the target is to get something like

[ ['0', 'a'], ['1', 'b'], ['2', 'c'] ];

From

"maxRU=5000;database=rktmb_credit;counting=databaseLevel"

In order to achieve that, we need a small utility:

const parseDescription = function (d)  {
    var a1 = d.split(";");
    var r = a1.map(f => {return f.split("=");});
    return r;
}

And this is how it executes in a Node REPL:

mihamina@a-onp ~]$ /home/mihamina/Apps/node/bin/node 
Welcome to Node.js v16.17.0.
Type ".help" for more information.
> const parseDescription = function (d)  {
...     var a1 = d.split(";");
...     var r = a1.map(f => {return f.split("=");});
...     return r;
... }
undefined
> result=Object.fromEntries(parseDescription("maxRU=5000;database=rktmb_credit;counting=databaseLevel"));
{ maxRU: '5000', database: 'rktmb_credit', counting: 'databaseLevel' }

We got what we want.

npm run build base-href

Using NPM to specify base-href When building an Angular application, people usually use "ng" and pass arguments to that invocation. Typically, when wanting to hard code "base-href" in "index.html", one will issue: ng build --base-href='https://ngx.rktmb.org/foo' I used to build my angular apps through Bamboo or Jenkins and they have a "npm" plugin. I got the habit to build the application with "npm run build" before deploying it. But the development team once asked me to set the "--base-href='https://ngx.rktmb.org/foo'" parameter. npm run build --base-href='https://ngx.rktmb.org/foo did not set the base href in indext.html After looking for a while, I found https://github.com/angular/angular-cli/issues/13560 where it says: You need to use −− to pass arguments to npm scripts. This did the job! The command to issue is then: npm run build -- --base-href='https://ngx.rktmb.org/foo&

emacs29 intelephense

Emacs 29 and PHP Intelephense I use to use Emacs and PHP Intelephense for PHP development. I recently upgraded to Emacs 29 and PHP Intelephense stopped working. I found a solution on Reddit Based on that, I rewrote my .emacs file to use eglot instead of lsp-mode, and this is the result. (use-package eglot :ensure t) (add-hook 'php-mode-hook 'eglot-ensure) (use-package php-mode :ensure t :mode ("\\.php\\'" . php-mode)) (add-to-list 'auto-mode-alist '("\\.php$" . php-mode)) (provide 'lang-php) (use-package company :ensure t :config (setq company-idle-delay 0.3) (global-company-mode 1) (global-set-key (kbd "M- ") 'company-complete)) (require 'eglot) (add-to-list 'eglot-server-programs '((php-mode :language-id "php") .
