[X] do I have access to Alain’s config?
- Alain M. Lafon
- preek666 on Youtube
- I don’t think so.
- He is munen on github. His literate emacs config is: https://github.com/munen/emacs.d/
- So I do have his config locally
add some bindings for:
- split window
  - vertically
  - horizontally
or maybe work on shell mode?!
- Explore the three shell modes in the play emacs like an instrument video (local copy)
  - it looks like Alain was using eshell mostly
- and there is Howards Introcution to Eshell (local copy)
  - and the notes to the talk
switch to counsel and see if I prefer it to helm?
- that might also enable tramp mode, which I would like to get done
explore winner mode to manipulate a stack of window configurations
explore undo-tree
explore the limits of dired mode
- learn to make new directories
- move files around within those directories

Done

[X] rm .emacs.jwm.d
- vega
- sift mac
[X] git rm the classic config from jwm-dotfiles
[X] fix diff-dot-files to use the literate emacs config

Done

[X] investigate helm-occur as a replacement for isearch and/or swiper
- no, I decided to use swiper for C-s
[X] exec-path-from-shell
- evaluated, and I am not going to use this at this time.
[X] consider moving my old revert-buffer binding from C-x y to C-c u per Daniel
[X] consider setting up abo-abo’s ace-window
- Daniels use of it
[X] json-mode
[X] Daniels org-babel config looks good for my use case
- [X] and this org-structure-template-alist stuff
- well I didn’t actually do the alist stuff, but good enough for now.

Done or Otherwise Completed

[X] Consider swapping out my default emacs config for this new one.
[X] Turn off all disabled emacs commands; follow Howards config there.
NO NOT NEEDED company
- do I use this now? I am not really sure
- is this compatible with ivy, swiper, counsel?
- I don’t think so.
- I think company and counsel are both completion frameworks
[X] babel
- enough to support shell
- and particularly iterating on jq recipes
- from Daniel Mai
[X] js2-mode
[X] json-mode
terraform-mode
[X] crux
- which of these functions do I actually use?
  - rename buffer and file every once in a while
- yes, probably add this back in
expand-region

explore using PCRE regexp patterns across emacs

State “DONE” from [2019-09-11 Wed 22:48]

this seems like a win to me; only one regex syntax to remember.

package: pcre2el

But this package has not been updated since 2016.

And its author recommends learning emacs regexp syntax.

So pass on this package.

I can just group all of that source code into my single literate file.

is this a new gh repo? A: no. Put it in jeff-dotfiles

DEFERRED move jeff-dotfiles to github from bitbucket

State “DEFERRED” from [2019-07-21 Sun 12:30]
I don’t need to do this now; instead, create a separate emacs repo.

[these notes](https://gist.github.com/mandiwise/5954bbb2e95c011885ff) suggest that there is a githum import tool. check it out. 2FA did not work with that tool. This still makes sense for my dot files, to move them out of bitbucket I can move them around by configuring additional git remotes and syncing them that way.

plan the transition

State “DOING” from [2019-07-21 Sun 12:59]

how do I evolve my current config into a literate form while not screwing up my working emacs? A1: git branches Just build the new config on a git branch. Start the master with the git config at: jwm-dotfiles/.emacs.d and .emacs.jwm.d But that suggests that I collapse the .emacs.jwm.d functions into the main init.el first.

[X] So evaluate if I need any of those older functions.

choose to move the .emacs.d in and out of the home directory to facilitate working the transition.

[X] write 2 shell scripts to make it easier to rotate between configurations
- prefer-literate-emacs-config
- prefer-classic-emacs-config

figure out how to tangle init.el from the org file

State “DONE” from [2019-07-21 Sun 16:12]

munen: Alain doesn’t do any tangling of the org file into the init.el file; he just loads in the org file using org-babel-load-file check out SriPscl he does much the same as munen seems like this is a way to get bootstrapped here. what does Howard Abrams do? Howard has split out his org file into many individual file and has a build script (written in elisp) what does Sacha do?

My ~/.emacs.d/init.el is now a symlink to Sacha.el, which is what M-x org-babel-tangle (C-c C-v t) produces.

So Sacha writes her changes to Sacha.el, then tangles it, then revision controls the pair of files. She also splits out each elisp into a separate buffer with =C-c ‘= then she can run the debugger or eval buffer —- Decision: I am going to follow Sacha’s pattern, with one org file that I explicitly tangle

no, skip that intro; it appears to be quite out of date. it refers to a variable? org-babel-interpreters which doesn’t exist in my emacs.

[X] So read Working with source code in the guide instead

structure of a block

State “DONE” from [2019-07-30 Tue 20:37]

#+NAME: <name>
  <body>

switches: control the export of the block header args: control many aspects of the code block behavior

editing blocks

State “DONE” from [2019-07-30 Tue 20:37]

Use C-c ’ to enter and exit an evaluation buffer for that block

evaluating code blocks

State “DONE” from [2019-07-30 Tue 20:37]

Use C-c C-c in the block to evaluate it and insert its results in the emacs buffer. By default, only emacs-lisp is supported; other languages must be explicitly turned on. See the manual. (where?)

State “DONE” from [2019-07-30 Tue 20:37]

According to the manual, this function will enable babel support for added languages

(org-babel-do-load-languages
 'org-babel-load-languages
 '((emacs-lisp . t)
   (shell . t)))

Ok, that worked. So now try to execute some shell

awk '{print $2}' <<=eod
every good boy
does fine
eod

Ok, now figure out how to name which shell is invoked

sh_pid=$(echo "$$")
ps uww $sh_pid

good it is my shell; zsh

Looks like easy templates have what I want for expanding blocks of examples, especailly shell code

< - e  expands to BEGIN_EXAMPLE

and editing in those source blocks with ~C-c ‘~ is explicitly supported.

(defun xor (a b)
       (if (a
            a
            ! b)))

this example is not valid emacs-lisp

write the first version and figure out how to get emacs to execute it

State “DONE” from [2019-07-30 Tue 23:30]

start with the basics

figure out how to make the most basic, valid emacs config initialization file
and test it
- test the init fragments inside each block with C-c '= and =eval-buffer
- then tangle and
  - emacs -Q -l init.el

how does Sacha tangle her file?

She names the output file in a file-scoped property, then runs C-c C-v t to generate that output.

Initial Goals [4/4]

[X] switch to a literate construction method for emacs
[X] prefer ivy, counsle and swiper over helm

[X] read the smex docs
- github README
> Smex is a M-x enhancement for Emacs. Built on top of Ido, it provides a convenient interface to your recently and most frequently used commands. And to all the other commands, too.
[X] does abo-abo use smex in his configuration?
- A: he loads it, but doesn’t appear to configure it
so I don’t think smex is going to work for me with counsel
there is helm-smex though, so I could have smex if I went back to helm it appears

do I use ido? or just ivy, counsel and swiper

State “DONE” from “DOING” [2020-02-01 Sat 18:53]
- State “DOING” from [2019-07-21 Sun 12:59]

arguments in favor of ido
- I believe Sacha uses it
- where ivy doesn’t work well

For now, I am going to stick with counsel and swiper.

write an emacs <something> hook that runs whitespace-cleanup

State “NEXT” from “TODO” [2020-02-01 Sat 18:16]

<2019-10-28 Mon>

dir-locals.el approach

define a directory local variable?

then the file save hook runs based on that?

I have an example /Users/jeff/jwm/proj/zsh-hacking/.dir-locals.el

Here is an example from copyright.el of a before-save-hook

How do I create a dir-locals.el file? A: M-x add-dir-locals

(add-hook 'before-save-hook (lambda () (whitespace-cleanup)))

when I think the hook was working, I had this for the value of before-save-hook

((lambda nil
   (whitespace-cleanup)))

well this, didn’t work so well for me. Mostly because I could not rationalize how to evaluate the variable at the correct time. Should I use `add-hook`? Wouldn’t that cause multiple copies of the hook to be added?

so bind it to org-mode at init time? No.

make a function (hook) that runs whitespace-cleanup based on some jwm- variable on hooked to `before-save-buffer`. then set that variable in a dir-locals.el to apply to the scopes that I want that behavior in:

~/jwm
~/sift

jwm-clean-whitespace-on-save-buffer

Working code

then run `add-dir-local` at a directory scope to set jwm/run-whitespace-cleanup-on-save-p where desired.
