CentOS6 packaging basic environment

When working on packaging some unpackaged yet software for CentOS, I often start with a clean minimal VM and then setup a new development+packaging environment.

This becomes repetitive so that I needed a memo in order to just copy/paste.

Note that this is just the very basic packaging tools I need and this does not override any official packaging guide.

sudo yum -y install rpm-build rpmdevtools redhat-rpm-config make gcc autoconf automake gcc-c++ yum-utils
sudo yum -y groupinstall "Development Tools"

Then I install the complete build dependencies depending on the package I want to build.

After this, I have to setup a minimal build environment:
mkdir -p ~/rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
echo '%_topdir %(echo $HOME)/rpmbuild' > ~/.rpmmacros
When building with "rpmbuild" I might encouter some insatisfied build dependencies.
This is solved with 

yum-builddep /path/to/package.spec

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='' 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=''" parameter. npm run build --base-href=' did not set the base href in indext.html After looking for a while, I found 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='

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") .
