OK Vim wizards

How do I copy something into a register which is NOT AN ENTIRE LINE?

@feersum v<select your thing with arrows>y

No that doesn't help.

It just puts it into the default register

And gets overwritten by something else right away.

I want to use a named register.

Q: Can questions be too hard?

I have an idea for a code-golf question and, in my opinion, I believe that it is quite a difficult problem to code in the first place, let alone to golf.

@DownWat do you have any idea on how I could route from express to your rails?

@Downgoat What is express? Also, I took it down, but it's on Github. Just clone it, cd in, run bundle install then rails server

@DJMcMayhem That's it, thanks.

@Downgoat The application exposes a JSON-based API

1:24 AM

I was trying "av...y before.

@DownWat I have existing middleware so is there a way to route that to rails

I.e. Can't run on 127.0.0.1:80

@Downgoat Yeah, you need to run the server, then you can get the post index from /stories.json and individual posts from /stories/[id].json

It hosts itself on port 3000

There's also some endpoints that you can POST PATCH or DELETE to

The endpoints can't be root

You can use those to submit, edit, etc.

is there a way to configure that?

1:26 AM

Define root

Im gonna do a ProxyPass /app 3000 so your endpoints won't be called if their listening on root

code-golf arithmetic

Yeah AFAIK you can POST to /stories/create (?) let me check

OK @Downgoat I've figured out the API endpoints

POST /stories.json {"title":"", "author":"","school":"","content":""} returns the full JSON with id, dates, and URL.

PATCH /stories/x.json {"title":"", "author":"","school":"","content":""} edits a story and returns the stuffs

DELETE /stories/x.json deletes that story

The updated app should be on GitHub. You're on a Mac AFAIK so just gem install rails.

cd into the folder, run bundle install && ruby bin/rails db:migrate && ruby bin/rails server

@Downgoat

@DownWat I'm on Debian :P

then apt-get install ruby and same steps

@DownWat It's kinda difficult to keep track of your name because I've only noticed you around here for about half a year at most (and that's exaggerating a bit) and I remember you having at least 6 usernames

@Mego Good idea. I agree, I don't like username trends because they just get boring really quickly

IMO Mendeleev looks more professional and it also has more relation to my real name (Dmitry)

Funny seeing the today's xkcd since my vim question earlier was for an editor with vim keybindings, not actual vim.

Personally, I use Sublime Text.

Does it have vim key bindings?

Probably not? It's not macro Heavy.

@feersum sublimetext.com/docs/3/vintage.html

@ATaco What are you talking about, every editor has vim bindings

even the one on Cloud9

Well of course someone has made them, I meant A taco personally.

@feersum But vim mode pretty much always comes built in (but disabled)

I wonder what happens when you disable vim mode in vim.

@feersum That's pretty much what insert mode is, isn't it?

@DownWat Question: can I use rails to generate HTML so I don't need to do "loading" and AJAX calls

@Downgoat Yeah of course! You write your template in erb, the existing templates are at app/views/stories/*

@DownWat "Login" header needs to be closer to center, and I feel google login button is not left-aligned with signin but otherwise looks nice

AJAX would be nice though

@Downgoat Can you try the login?

@DownWat :O I can smoke the templates? :P

@Downgoat Define smoke

Just edit them

@ASCII-only Cool, tahnks. Does it show your profile picture?

> No route matches [GET] "/transactions/check/out

@DownWat yeah, logout button is a little misaligned though

@Downgoat Yeah, I'm rewriting the whole app due to some bad decisions I made early on. I am working on reimplementing that.

@ASCII-only That's true and I need help from someone who knows how to web design.

@Downgoat, can you please help?

ok yeah I see logo

@DownWat sure, not familiar with material design but can try >_>

3:47 AM

@Downgoat Basically, app/views/layouts/application.html.erb and app/views/stories/*.html.erb are what you need to edit.

There's also app/assets/stylesheets/application.css and app/assets/javascripts/application.js which get included into the template as well.

@DownWat hm, could I serve the .html/.css files at a different domain than the API endpoints? I like my API endpoints to be at api.vihan.org and the app at vihan.org

@Downgoat Umm, the app isn't really aware of domains. It serves everything relatively.

D:

AJAX it is

I mean, you could access things through api.vihan.org... it would just be accessible from both places.

@Downgoat You don't need AJAX. The API endpoints are not needed if you are working with the HTML/CSS files, you would just access the pages directly

at something like /stories/new or /stories

@DownWat oh, and how would the form submission for /stories/new work? what would be the endpoint there?

3:51 AM

The form POSTs to /stories which triggers the create action of the controller.

If you look in app/views/stories/_form.html.erb you can see the FormHelper code.

You can add CSS classes to the form fields by appending , :class => "classes-list test" to the f.whatever :whenever

Actually, you can append most HTML attributes (id, for, etc.) through that mechanism, e.g. :for => "whatever"

It's a hash/associative-array

Also, beware of app/assets/stylesheets/scaffolds.scss it contains some font overrides, you can get rid of everything before #notice

Just making sure: @Downgoat
