Is this white page some sort of satire or is it down?
- memorable 4y ago
  It's down ATM. I found a Wayback Machine snapshot for proof. https://web.archive.org/web/20220614131126/https://plaintextco.in/ https://web.archive.org/web/20220614131126/https://plaintext...

That's awesome. Some things that can be improved: - The UI is left justified on my mobile browser. It will look better if it is centered. - The font is too small. Perhaps you could increase font size so users don't have to zoom in. Also, did you a framework to generate plaintext front-end or is it hand crafted?
- guillaumec 4y ago
  Thanks for the comment! I wanted to keep the html and css as simple as possible so I didn't put much layout. If it gets traction I will improve that. Same thing for the font. It's all hand crafted. My first time using golang so the code is probably not as efficient as it could be.

    Really? It even renders ascii and colors properly in a terminal with curl !!! \xe2\x94\x82\n\xe2\x94\x94\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x98\n

Plaintext and ascii art are in this year and that’s cool to me. Nice work.
sodality2 4y ago
Getting a 504 :(
- guillaumec 4y ago
 Yeah the server is not handling the load at the moment... I am trying to restart it.
 - KyleBerezin 4y ago
 The curse of Hacker News attention
 - guillaumec 4y ago
 Well, I should have tested a bit more before posting.
 - nominusllc 4y ago
 Is the source posted somewhere? Maybe we can help
 guillaumec 4y ago
 Not at the moment, this was a week end project, and the code is quite horrible. But yes I should probably put it online and get advise.
 nominusllc 4y ago
 pas grave, post it :)

 An intriguing failure mode (response body seems truncated) $ curl -i https://plaintextco.in/ HTTP/2 504 date: Tue, 14 Jun 2022 14:13:44 GMT [more headers] cf-ray: 71b3ab17fc7254d5-MAN <!DOCTYPE htm
rabuse 4y ago
All I see is a white page.
- memorable 4y ago
  Same here. Hug of death.
bluetidepro 4y ago
HN hug of death, I assume.
- matthewcford 4y ago
  I assumed the prices were 0, hence the empty webpage.
olalonde 4y ago
Pretty cool, I noticed it works both in the browser and command line. I suppose you are using the User-Agent header to detect which version to serve? Which library did you use for the interface?
- guillaumec 4y ago
  It's all done by hand in go. Yes it uses the user agent to guess if the request comes from a terminal.
KyleBerezin 4y ago
Firefox 101.0.1 on Windows didn't seem to render it correctly. I was going to compare it to chrome but then the server died. Very cool page though. Update: the server is back up and it looks fine on Firefox now. false alarm
danuker 4y ago
This is awesome! I will be able to check the prices without spinning up my old laptop's fan. My preference for time is much longer-term. Trading too often can lead to ruin due to transaction fees (and/or emotion). I'd use the 1 day, 30 day, and 365 day price changes instead of 1h, 24h, 7d. Another small issue: I can't use autoscroll in Firefox because the whole page width is a link.
giantrobot 4y ago
I got a blank page...did crypto prices drop that much today?
j_leboulanger 4y ago
Here is an extract of what happens in terminal : curl https://plaintextco.in/coins/bitcoin https://plaintextco.in/coins/bitcoin <!DOCTYPE html> <title></title> <meta name="description" content="Plain text cryptocurrency prices"> <style> @font-face { font-family: 'dejavu-sans-mono'; src: url('/static/DejaVuSansMono.ttf') format('truetype'); } * { font-family: 'dejavu-sans-mono'; font-size: small; line-height: 120%; } </style> <h1>plaintextco.in</h1> <h1></h1> <pre> Bitcoin (BTC) Price $22,183 <span style="color: #f9a53f;ba It's impossible to read :(
- guillaumec 4y ago
 Actually it also supports a black and white mode using only utf8 characters. I haven't exposed it yet though.
 - paulnpace 4y ago
 Lynx looks great.
- jasonjayr 4y ago
 Elinks in a terminal with 256 color + utf-8 renders it pretty decently. https://imgur.com/a/NPsN5N5 https://imgur.com/a/NPsN5N5

Interesting. I wasn't aware that you could use a Cloudflare IP address along with a different name server.
- captn3m0 4y ago
  Cloudflare Worker perhaps
- lxgr 4y ago
  Maybe they're using something like an ALIAS record instead of a CNAME setup?
julianeon 4y ago
This is really nice. Great work.
lazyvar 4y ago
Some small feedback if I may: Could you separate the link and the text on the main page? My first thought was: "This isn't text. I can't highlight or copy anything. It's actually the opposite of what the title says." But everything was as advertised when viewing an actual coin. Cool site! Cheers!
- guillaumec 4y ago
  You are probably right. I should also probably add a link to a 'true' plain text version that returns a pure txt.

I get randomly HTML and ASCII in the terminal, otherwise cool product. It would be nice to configure a list of coins to be displayed. Something like: https://plaintextco.in/collection/btc+tezos+near Also, you could reduce the HTML size significantly by using instead of and create a classnames for the colors.

 - tiborsaas 4y ago
 oh cool, it's now ready for bookmarking :)
- guillaumec 4y ago
 Yes, since I got too many requests from HN, I had to enable the CDN. I didn't realize it would cache both html and terminal request together. I tried setting "Vary: User-Agent" but it didn't work. You can add: "?term=true" to make it work in terminal for now.
 - weird-eye-issue 4y ago
 I think Vary: Accept-Encoding or similar is the solution for this but not sure

Oh. From the headline I was hoping for something easily parseable.
