;;; index.el --- isamert's configuration -*- lexical-binding: t; -*-

;;; Commentary:

;; isamert's configuration

;; This is my Emacs configuration. My main focus is sanity. I'm a
;; person who get frustrated pretty easily. So instead of optimizing
;; the time spent on doing things, I try to find ways of doing things
;; that does not make me frustrated. Most of the time you get speed
;; boost as a byproduct.

;;;; Emacs installation

;; I use my distributions package manager to install Emacs. However,
;; in MacOS (my work computer) I use /homebrew/ and /emacs-plus/
;; formula. Here is how you install it:
;;
;; #+begin_src sh
;;   brew tap d12frosted/emacs-plus
;;   brew install emacs-plus@30 \
;;        --with-dragon-icon \
;;        --with-dbus \
;;        --with-imagemagick \
;;        --with-poll \
;;        --with-debug
;; #+end_src
;;
;; There are also other nice Emacs distributions, like:
;;
;; - https://github.com/jimeh/emacs-builds
;; - https://emacsformacosx.com/
;;
;; But I need the aforementioned switches and patches. Otherwise these
;; are very good.
;;
;; * --with-poll
;;
;; You can read about the options [[https://github.com/d12frosted/homebrew-emacs-plus#options][here]], but the most important one is
;; ~--with-poll~. Otherwise you'll get lot's of /no file descriptors
;; left, too many files are open/ errors, especially if you are using
;; LSP etc..
;;
;; * --with-debug
;;
;; It is nice for debugging crashes or freezes. Helps you get a better
;; output from the debugger. When Emacs freezes and ~pkill -USR2 Emacs~
;; is not helping, what you can do to debug the issue is:
;;
;; #+begin_src sh
;;   $ cd ~/Library/Caches/Homebrew/emacs-plus@30--git/src
;;   $ lldb --local-lldbinit /opt/homebrew/Cellar/emacs-plus@30/<VERSION>/Emacs.app
;;   (lldb) r # → Do this to start emacs
;;   # wait for the freeze
;;   # C-c to quit the Emacs after freeze
;;   (lldb) xbacktrace # or bt
;; #+end_src
;;
;; Same story with crashes. Just run Emacs through =lldb= all the time
;; and be prepared I guess...

;;;; Usage notes

;;;;; General notes and conventions

;; - This configuration is meant to be used with /emacs daemon/, so I don't really care about the startup time etc.
;; - I try to split package configurations into multiple org src blocks and unify them using ~noweb~ references under a single =use-package= directive.
;; - I try to put things in way that easily copyable from the configuration. An example would be using multiple =(setq ...)= lines instead of having one =(setq ... ...)= call and setting multiple variables in one go.
;; - I make use of =use-package= features quite minimally. See [[id:3d974e67-11fc-4f07-8cd4-ec6fd63152c4][here]] for more information that. This is generally related with the item above and future-proofing.
;; - I use =verbatim text= and ~code text~ completely randomly.
;; - I try to prefer built-in packages or packages that enhances built-in ones where possible. I'm also trying to simplify my configuration, so another goal is to reduce the package number. Although I intend to keep packages that enhances the overall experience with no special configuration (just install and forget type of packages).

;;;;; Keybinding conventions

;; - After leader
;;   - =e= :: is reserved for independent programs, that is not related to editing/programming. For example, "ec" opens calendar, "ee" opens elfeed, "er..." controls the radio.
;;   - =t= :: is reserved for toggling stuff. Toggle the terminal, toggle a frequently accessed buffer etc.
;;   - =h= :: is reserved for any menu with fuzzy selection that does not fit anywhere else.
;;   - =g= :: is for git related functionality.
;;   - =p= :: is for project related functionality.
;;   - =/= :: is for search/translate related functionality. (Generally external programs)
;;   - =b= :: is for buffers.
;;   - =w= :: is for windows. I also use =C-w= for this, which is default prefix for window-related functions in vim.
;;   - =o= :: is for org-mode/outline mode.

;;;;; Updating packages

;; Just do ~M-x straight-pull-all~. I do this quite infrequently. If
;; everything is working fine as it is, I tend to not update anything.

;;; Code:

;;;; Preparation

;;;;; straight.el and use-package

;; Useful to see which packages take long time to load
;; (require 'use-package)
;; (setq use-package-compute-statistics t)
(setq use-package-enable-imenu-support t) ;; With that, IMenu will show packages section

(defvar bootstrap-version)
(defvar straight-base-dir)
(let ((bootstrap-file
       (expand-file-name "straight/repos/straight.el/bootstrap.el" (or (ignore-errors straight-base-dir) user-emacs-directory)))
      (bootstrap-version 5))
  (unless (file-exists-p bootstrap-file)
    (with-current-buffer
        (url-retrieve-synchronously
         "https://raw.githubusercontent.com/raxod502/straight.el/develop/install.el"
         'silent 'inhibit-cookies)
      (goto-char (point-max))
      (eval-print-last-sexp)))
  (load bootstrap-file nil 'nomessage))

(straight-use-package 'use-package)

(use-package straight
  :custom (straight-use-package-by-default t))

;; I tend to not use the =use-package= goodies while configuring my
;; packages, meaning that I don't use =:hook=, =:bind= etc. as they
;; have relatively simpler alternatives in Emacs and using
;; =use-package= alternatives of these makes copy/pasting harder. Here
;; are the keywords that I use the most:

;; - =:init= :: This gets called before the package gets initialized.
;; - =:config= :: This gets called after the package is initialized.
;; - =:after= :: This makes the current definition to wait the loading of listed packages, like =:after (evil org)= makes it wait for the =evil= and =org= packages to be loaded.
;; - =:if= :: Loads the package conditionally, like =:if (eq system-type 'darwin)=.

;;;;;; Hiding mode indicators from modeline

;; ~diminish.el~ provides a way to hide mode indicators from mode
;; line. Either pass ~:diminish t~ to use-package while installing or
;; just call ~(diminish 'x-mode)~.

;; (use-package diminish)

;; Currently I use [[mini-modeline]] as my modeline and it already
;; hides minor mode indicators from the modeline. So this package is
;; not needed but better have it as I might change my modeline in the
;; future.

;;;;; Load path

;; Also load ~im-secrets~ from =load-path=. I'll be utilizing some
;; variables defined here throughout my configuration. It contains
;; some api-keys, some tokens or some passwords etc. that I don't want
;; to leak into public. Instead of doing mutations on an external
;; hidden script, I define variables in this external hidden script
;; and reference them in the configuration. This way the logic stays
;; in the public configuration file so that everyone can take a look,
;; but only the variable itself will be hidden from the public.

(require 'im-secrets)

;;;;; Essential packages

;; I use =s.el= and =dash.el= extensively. They already come as a
;; dependency with other packages but I may use them before loading
;; any package, so:

;; Some lesser known functions:

;; - After converting to table, I can use ~org-table-sort-lines~. Alternative is using ~sort-fields~ without converting the data into table but it's not that nice to use.
;; - I generally use it in combination with ~embark-collect~. Any completing-read → embark-collect → orgtbl-create-or-convert-from-region.

;; - =M-y= brings up =consult-yank=, where you can select from clipboard history and paste.
;; - =C-f= does fuzzy search on current file lines.
;; - Do =M-,= on a candidate to preview it.
;; - Also don't forget to utilize =M-a= (=embark-act=) in consult windows.
;; - Use =M-n= (future-history) to insert current symbol after running a consult command. Normally you would use =M-{p,n}= to cycle between history items but when you open minibuffer, typing =M-n= directly tries to guess what the user input would be.

;;;;; embark

;; =embark.el= provides contextual command maps.

;; - =M-a= activates command mode. Next key should be command. Do =C-h= to list all commands with their keybindings.
;; - Commands are context specific, ie. the commands is based on if currently selected item is a file, folder, buffer etc.
;; - It's mostly used within the minibuffer, some example functions:
;; - =M-a w= (~embark-save~) saves the current candidate's text into kill-ring.
;; - =M-a i= (~embark-insert~) like the one above but instead of saving to the kill-ring, it directly inserts it to the buffer.
;; - =M-a S= (~embark-collect-snapshot~) creates a buffer containing all the candidates.

;; - To apply an action to multiple items, filter the items first and then do =embark-collect-snapshot=. A buffer will open and you can apply the main action or other actions on the items.

(use-package ol-notmuch

;; Easy to use, fast email client.  Tagging feature is something I am
;; familiar from elfeed, and notmuch executes this concept very
;; well. A pleasure to use.

;; Summary of what is going on:
;;
;; - `mbsync' (or `isync') is used for fetching mail from remote mail
;;   server to local.
;;   - The configuration is kept under =~/.mbsyncrc=
;;   - This needs to be run periodically to sync mail.  See my
;;     `im-sync-mail' function.
;; - `notmuch' is the mail indexer which essentially lets you search
;;   your mail.
;;   - The configuration is kept under =~/.notmuch-config=
;;   - It is an external program, that works on your local maildir
;;     (which is created by the `mbsync')
;;   - It needs to be run after each update to index your mail.  See
;;     my `im-sync-mail' function.
;;   - It is also an Emacs package which let's you view your email and
;;     interact with them.
;; - `msmtp' is the SMTP client that let's you send your mails.
;;   - The configuration is kept under =~/.msmtprc=.
;;   - See `sendmail' and `message' configuration down below for Emacs
;;     integration.
;;
;; See [[../index.org]] for relevant configuration files.
;;
;; Great video, explaining notmuch and the workflow by prot:
;; https://youtube.com/watch?v=g7iF11qamh8
;;
;; For gmail configuration, following is helpful:
;; https://frostyx.cz/posts/synchronize-your-2fa-gmail-with-mbsync#gmail-with-2fa
;;
;; Another helpful and easy to follow guide:
;; https://jonathanchu.is/posts/emacs-notmuch-isync-msmtp-setup/
;;
;; Most of the customizations down below are inspired by prot's configuration:
;; https://protesilaos.com/emacs/dotemacs

;; Good time to set these values:

;;;;;; REPLs

;; I really like being able to do my development inside REPL. It

;; process. While support for this type of development is not good in
;; other languages than Lisps, I at least like to have the ability to
;; run and evaluate pieces of code in given languages REPL.

;; Here I created a function to ease up that process. For given REPL,
;; this creates a background REPL process (like ~jshell~) and sends
;; your inputs to REPL and outputs the result to echo area. It's like
;; ~eval-last-sexp~ but for all languages that has a REPL (and with
;; much limited execution functionality of course, you are limited by
;; the REPL.)

;; This creates only one REPL process per language, so you can build
;; up a context and use that throughout your projects.

NAME is the binary name of the REPL, like jshell, deno etc. (case-insensitive)

ARGS is the arguments passed to NAME.

PREFIX is the prefix used while showing the result in echo area.

INPUT-REGEXP is used to detect the input line of the REPL.

EXPR is the expression finder at point.  Should return a
tree-sitter node.

PARSER is result parser.  Process output is sent to this function
and if the return value is non-nil, result is shown in the echo
area.

As a result, 3 functions are generated:

- im-NAME-repl-start :: Creates the process and starts the repl.
  Process is associated with *NAME-repl* buffer.

- im-NAME-repl-send :: Sends given string to REPL.

- im-NAME-repl-eval :: Entry function.  Just bind this to
  something and it starts a REPL if needed when called and sends
  the current expression (or the selected expression) to REPL.

  '(defun lisp-indent-function (indent-point state)
     "This function is the normal value of the variable `lisp-indent-function'.
The function `calculate-lisp-indent' calls this to determine
if the arguments of a Lisp function call should be indented specially.

INDENT-POINT is the position at which the line being indented begins.
Point is located at the point to indent under (for default indentation);
STATE is the `parse-partial-sexp' state for that position.

If the current line is in a call to a Lisp function that has a non-nil
property `lisp-indent-function' (or the deprecated `lisp-indent-hook'),
it specifies how to indent.  The property value can be:

* `defun', meaning indent `defun'-style
  \(this is also the case if there is no property and the function
  has a name that begins with \"def\", and three or more arguments);

* an integer N, meaning indent the first N arguments specially
  (like ordinary function arguments), and then indent any further
  arguments like a body;

* a function to call that returns the indentation (or nil).
  `lisp-indent-function' calls this function with the same two arguments
  that it itself received.

This function returns either the indentation to use, or nil if the
Lisp function does not specify a special indentation."

;; * Jupyter & org-mode
;;
;; - =jupyter= package enables you to use jupyter notebooks in Emacs.
;; - It provides two ways, one is through org-mode and it's the one I
;;   prefer.
;; - You need to convert =ipynb= files into org-mode files by running:
;;
;; #+begin_src sh
;; pandoc --from ipynb --to org some-file.ipynb # this outputs an org-mode file
;; #+end_src
;;
;; - Do =jupyter-connect-repl=.
;; - Start (?, not sure, it may be automatic)
;;   ~jupyter-org-interaction-mode~ and then you will get completion at
;;   point
;; - Then you can simply use jupyter-python source blocks to write
;;   your code and run them exactly as you do with normal org code
;;   blocks.
;; - There are also these functions which you can utilize:
;;   - jupyter-eval-defun
;;   - jupyter-inspect-at-point      → K
;;   - jupyter-eval-line-or-region   → C-x C-e
;;   - jupyter-repl-interrupt-kernel → C-c C-i
;;   - jupyter-repl-restart-kernel   → C-c C-r
;;
;; * Virtual Envs and Jupyter
;;
;; If you are using virtualenvironments, then simply do
;; =pyvenv-activate= and select the virtenv folder.
;;
;; You can create a venv like: =python3 -m venv <venv-folder>=. To
;; install requirements.txt dependencies, do ~pip install -r

;;;;; My Android phone and Emacs

;; I have an Android phone that is running
;; [[https://termux.com/][Termux]] all the time. If you install Termux
;; through [[https://www.f-droid.org/][F-Droid]] you can also install
;; [[https://f-droid.org/en/packages/com.termux.api/][Termux:API]]
;; package which brings bunch of commands like =termux-clipboard-set=,
;; =termux-sms-list= etc. Much of the commands requires to be called
;; in foreground, so they are not very useful over SSH but you can
;; work around that by starting a =tmux= session on the phone and
;; executing commands on that tmux session through SSH. This way I can
;; send arbitrary text to my phones clipboard using the commands
;; below.

Path may have a trailing “:‹n›” that indicates line number, or
“:‹n›:‹m›” with line and column number.  If so, jump to that line
number.  If path does not have a file extension, automatically
try with “.el” for elisp files.  This command is similar to

This is a wrapper around `start-process-shell-command' that adds
support for ANSI term colors and some syntactic convenience.

If ARGS is non-nil list, then use `start-process' with command as
COMMAND and args as ARGS.

ENV is a list of environment variables and values in the
following form:

    '(\"DISPLAY=\" \"X=5\" \"Y=6\")

If EAT is non nil, use eat shell to display output which handles
terminal outputs way better.  ARGS must be a list.

When called interactively, asks for a command to run (with eshell
completion).

In BUFFER-NAME, `im-shell-command-mode' is activated and you can
use `im-shell-command-mode-rerun-command' or \"gr\" to replay the
command.

If EAT is non-nil and BUFFER-NAME does not contain \"*...*\", the
asterisks will be added automatically by eat.

      (plot cos(x))

First argument is a plist which consists gnuplot configs or
variable definitions.  Configs are`:persist', `:default',
`:slow'. See `man gnuplot' for more information on these
settings. They can be either `t' or `nil'. Default is `nil' for
each one.

Variable definitions are like the `let' form, simply define
variables and use them in the gnuplot code below. Variable
namings should follow `:this-style:' and the values can be
arbitrary elisp.
