About

Visit Gist and see 'raw' link, It's including SHA-1 long hash name like this.

https://gist.github.com/raw/2370972/47150711fedb7375d19d761ab122485b8105678d/gist-raw-perm-HEAD.user.js

This user.js provide 'HEAD' links. It's takes shrinked permanent raw link and shrinked named raw link when you browse Gist files.

HEAD

True Permalink: This is absolutery permanent link but it's always filetype: txt.

https://gist.github.com/raw/2370972/

HEAD(named)

Almost Permalink: This is almost permanent link. It's strict filetype by extension. This link broken when filename changed.

https://gist.github.com/raw/2370972/gist-raw-perm-HEAD.user.js

This link most useful for install user.js from Gist.

Known Problems

Multifiles Gist

HEAD can accessible 1st file only. That is Gist API constraints.

Binary 1st file

e.g. https://gist.github.com/890279/

prob SOLVED, sort alphabetic? and text file order are top access to raw https://gist.github.com/raw/890279/ expected https://raw.github.com/gist/890279/simple320_320.png but actual API return 2nd text file data.

Gist API

Multifiles Gist has problem. Gist API is not provide true permalink(called HEAD) for 2nd or more files.

Gist API v3

Include content and history. it's too long too much than v1(closed).

The new Gist broke your script ＼( ><)シ

@LouCypher
thank you for your infomation :-)

broken

I know, maybe gist API changes too. but GitHub not provide information. hum..
a similar kind as shown below

feed => HTTP406

can't get gists feed

https://gist.github.com/noromanba.atom

Subscribe Gists - Hatena::Let

i.e. mulfunction open feed on flavors.me

blame UI

where is panel which put log?

• Show commit logs on Gist for Greasemonkey

too drastic.. I’m stucking X-(
I don't have much time now, a correction takes time.

FYI

didn't notification by Github, I'm late.
try @USERNAME with comments

Regards,
noromanba

@LouCypher
quick fix 🚑 now. but incompletly yet. pjax handling.........🐌
if unworks it, plz try reload

Thanks for the updates
       «:dancers::dancers:ヾ

@LouCypher
somehow handle pjax:sleepy::dizzy: thx for your patience:pray:

Would be great if you get this to work with the new style and upload new version to USO.

stuck in... 💭 take away freedom by CSP 🔒

@jerone sry I'm late. thx. USO has gone, and fork sites not good enough. e.g. GF; extreme security

Hey, @noromanba, I've updated the script to work on the current GitHub markup. Look at https://gist.github.com/denilsonsa/f2e5b9ee53e633e20165 and please update your version. :)

FYI, it was broken again, and I've fixed it again: https://gist.github.com/denilsonsa/f2e5b9ee53e633e20165
