emacs 26.2 as a birthday present

Emacs 26.2 has been released in April 12th, matching my 36th birthday, 

Appart from this coincidence, it's the first emacs release that has any code of mine, which makes me extremely happy. I only contributed 2 tiny bugfixes, but nonetheless I'm very happy about it :D

bypass zsh commands in bash

Here's a small trick I came out with, when trying to run some scripts that were thought for zsh in bash.

I use 'noglob' in many places, and sometimes they leak into my bash scripts, or are called from bash somehow.  As bash doesn't know about noglob, usual result is an error.

But! you can use this

cat <<-EOF >~/bin/noglob
#!/usr/bin/env bash
$*
EOF

So a bypass file is called in case the command 'noglob' is not catched by the shell.

EDIT: Now I remember why the f I created this.

You know I'm a heavy user of zsh's global aliases. my aliases that contain pipes are always UPPERCASE, because it gives a hint that something strange is happening there, and I also see it entering the realm of pipes. 

The thing is that when pairing with others, if I write that when they are looking, people have no clue what's happening when I type that, and it's pretty unintuitive.  Also, as my zsh and bash share part of the history, if I reach some command that contains one of the magic aliases, I've to manually fix them by expanding by hand.

1st fix: magic expansions

globalias() {
   if [[ $LBUFFER =~ ' [A-Z0-9]+$' ]]; then
     zle _expand_alias
     zle expand-word
   fi
   zle self-insert
}

zle -N globalias

bindkey " " globalias

This expands the previous word if it's an alias, but I only want to expand the ones that are ALL CAPSLOCK. Because I have very nasty aliases I don't want to expand as I go. (This has extra an benefit of allowing expansions of "dynamic aliases", which I'll show in some other post)


With this, I end up with noglobs scattered around my history, and if for some reason I execute those in bash, it'll try to run `noglob http ....`.  Here is where  ~/bin/noglob works fine by just bypassing everything.

emms ftw

I never got into the Emacs MultiMedia System, but just read that it has support for streaming radios so I gave it a try. And you know what?  It's awesome.  I'm adding all the radios I have in my radios repo.

But you already knew that.

Only a few concepts/commands:
- m-x emms-streams RET
- m-x emms RET
- c-+ + + +
- m-x emms-add-dired RET

Enough to get by and start using it.

FP vs OO talk

Here's a quite balanced talk about FP and OO that fits my view of the two paradigms. Give it a shot if you have 40mins on your commute or something.
