emacs typescript eglot

Emacs Typescript setup

I previously wrote an article on settting up Emacs for Typescript projects. It was years ago. I want to test new things..
Searching the Internet for new ways to setup, I found: TypeScript development with Emacs, tree-sitter and LSP in 2022
This did not work out of the box for me. I had to perform several intermediate actions, I do apologize that I dont fully remember everything, but here are what I remind...
Installing tree-sitter requires to have Rust installed before: 
    sudo pacman -S rust
corfu did not auto-complete anything, and I noticed that if I read the doc, I would have understood why: default setting does almost nothing. I stupidly switched to company
I dont know if it is related or not... but I installed tree-sitter-cli Node package. 
npm install -g tree-sitter-cli
Remid that I was in a try / error loop so I dont really know if this is relevant or not
Finally, this is my setting: 
    (use-package tree-sitter
  :ensure t
  :config
  ;; activate tree-sitter on any buffer containing code for which it has a parser available
  (global-tree-sitter-mode)
  ;; you can easily see the difference tree-sitter-hl-mode makes for python, ts or tsx
  ;; by switching on and off
  (add-hook 'tree-sitter-after-on-hook #'tree-sitter-hl-mode))

(use-package tree-sitter-langs
  :ensure t
  :after tree-sitter)
(use-package eglot
  :ensure t)

    ;; Ensure Eglot is launched on Typescript buffers
    (add-hook 'typescript-mode-hook 'eglot-ensure)

    ;; Ensure Company is maunched in all buffers (not Typescript only)
    ;; Please tell me a way to make it selective
    (add-hook 'after-init-hook 'global-company-mode)

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...

wget maven ntlm proxy

How to make wget, curl and Maven download behind an NTLM Proxy Working on CentOS, behind an NTLM proxy: yum can deal without problem with a NTLM Proxy wget, curl and Maven cannot The solution is to use " cntlm ". " cntlm " is a NTLM client for proxies requiring NTLM authentication. How it works Install "cntlm" Configure "cntlm"  by giving it your credentials by giving it the NTLM Proxy Start "cntlm" deamon (it listens to "127.0.0.1:3128") Configure wget, curl and Maven to use "cntlm" instead of using directly the NTLM Proxy Note: You will have then a kind of 2 stages Proxy : cntlm + the NTLM proxy Configure CNTLM After installing cntlm, the configuration file is in "cntlm.conf". You must have your domain (in the Windows meaning), proxy login and  proxy password. Mine are respectively: rktmb.org, mihamina, 1234abcd (yes, just for the example) You must have you NTLM Proxy Hostnama or IP ...

Undefined global vim

Defining vim as global outside of Neovim When developing plugins for Neovim, particularly in Lua, developers often encounter the "Undefined global vim" warning. This warning can be a nuisance and disrupt the development workflow. However, there is a straightforward solution to this problem by configuring the Lua Language Server Protocol (LSP) to recognize 'vim' as a global variable. Getting "Undefined global vim" warning when developing Neovim plugin While developing Neovim plugins using Lua, the Lua language server might not recognize the 'vim' namespace by default. This leads to warnings about 'vim' being an undefined global variable. These warnings are not just annoying but can also clutter the development environment with unnecessary alerts, potentially hiding other important warnings or errors. Defining vim as global in Lua LSP configuration to get rid of the warning To resolve the "Undefined global vi...
