# E-scripts on zig.
#
# Note 1: use the eev command (defined in eev.el) and the
# ee alias (in my .zshrc) to execute parts of this file.
# Executing this file as a whole makes no sense.
# An introduction to eev can be found here:
#
#   (find-eev-quick-intro)
#   http://angg.twu.net/eev-intros/find-eev-quick-intro.html
#
# Note 2: be VERY careful and make sure you understand what
# you're doing.
#
# Note 3: If you use a shell other than zsh things like |&
# and the for loops may not work.
#
# Note 4: I always run as root.
#
# Note 5: some parts are too old and don't work anymore. Some
# never worked.
#
# Note 6: the definitions for the find-xxxfile commands are on my
# .emacs.
#
# Note 7: if you see a strange command check my .zshrc -- it may
# be defined there as a function or an alias.
#
# Note 8: the sections without dates are always older than the
# sections with dates.

Zig language
https://ziglearn.org/

Source File
https://trendoceans.com/zig-programming-language/

- You don’t have to build or compile it, and it already comes in executable format. Just download and create a symbolic link for the binary file at the “/usr/bin” directory to make it executable from anywhere for that user, as shown below.

$ wget https://ziglang.org/builds/zig-linux-x86_64-0.10.0-dev.4560+828735ac0.tar.xz
After download, use the below command to extract the file.

$ tar -xf zig-linux-x86_64-0.10.0-dev.4560+828735ac0.tar.xz 

- Now enter into the directory and link it to the user bin directory as shown below.

- Note: After linking do not remove the source file, otherwise it will be broken link and Zig command will not be executed.

$ cd zig-linux-x86_64-0.10.0-dev.898+b23f10b42
$ sudo ln -s $(pwd)/zig /usr/local/bin/

- Now you can use the below command after the installation to check whether it is working.

$ zig version
0.10.0-dev.4560+828735ac0

zig-mode for emacs
https://github.com/ziglang/zig-mode

In doom emacs init.el uncomment:
;; (zig +lsp)

zls lsp server
https://github.com/zigtools/zls/#linux

curl -L https://github.com/zigtools/zls/releases/download/0.9.0/x86_64-linux.tar.xz | tar -xJ --strip-components=1 -C .

chmod +x zls
$ sudo ln -s $(pwd)/zls /usr/local/bin/

============
Emacs and Doom configuration

============
Emacs
Install lsp-mode from melpa
zig mode is also useful
;; Setup lsp-mode as desired.
;; See https://emacs-lsp.github.io/lsp-mode/page/installation/ for more information.
(require 'lsp-mode)

;; Either place zls in your PATH or add the following:
(setq lsp-zig-zls-executable "/usr/local/bin/zls")

============
Doom Emacs

Note: you do not need this configuration in doom, if you have enabled it on
"init.el"

Enable the lsp module
Install the zig-mode package (add (package! zig-mode) to your packages.el file
Add the following to your config.el:

(use-package! zig-mode
  :hook ((zig-mode . lsp-deferred))
  :custom (zig-format-on-save nil)
  :config
  (after! lsp-mode
    (add-to-list 'lsp-language-id-configuration '(zig-mode . "zig"))
    (lsp-register-client
      (make-lsp-client
        :new-connection (lsp-stdio-connection "/usr/local/bin/zls")
        :major-modes '(zig-mode)
        :server-id 'zls))))

============
Compiling source codes
zig can compile c, cpp and zip source files

zig myprog.zig
zig cc myprog.c
zig c++ myprog.cpp
