How to control GIST file listing order

PLEASE NOTE: This is NOT official specification document.

Basic Spec

  • Basically, ASCIIbetical order. But grouping by First character.
  • If two files have completely same name without casing, they will be ordered by creation time (older first).

First character

  • Some signs come before DIGITS
    • maybe !, #, - and . always come before digits 0-9.
  • Digits 0-9
  • Some signs come after DIGITS
    • maybe _ always come after digits 0-9.
  • Alphabetic characters come after signs and digits
    • ignore casing.

Extensions

Extensions are only characters part of filename.

Sample Cases

Case 1: same extensions

a_abc.txt, #_abc.txt, 1_abc.txt, __abc.txt will

Filenames
#_abc.txt
1_abc.txt
__abc.txt
a_abc.txt

Case 2: different extensions

a_abc.txt, #_abc.txt, 1_abc.txt, a_abc.md, #_abc.md, 1_abc.md, a_abc.js, #_abc.js, 1_abc.js, 2_abc.txt, 2_abc.md will:

Filenames
#_abc.js
#_abc.md
#_abc.txt
1_abc.js
1_abc.md
1_abc.txt
2_abc.md
2_abc.txt
a_abc.js
a_abc.md
a_abc.txt

Case 3: different names and same extension.

HIJ.txt, abc.txt, opQ.txt, HIK.txt will

Filenames
abc.txt
HIJ.txt
HIK.txt
opQ.txt

aaa.txt, ZZZ.txt will

Filenames
aaa.txt
ZZZ.txt

AAA.txt, zzz.txt will

Filenames
AAA.txt
zzz.txt

Thease means caracter-case are ignored.

Case 4: same name and extensions but different casing

a_abc.txt, a_ABC.txt

If you create a_abc.txt first, a_abc.txt comes before a_ABC.txt . If you create a_ABC.txt first, a_abc.txt comes after a_ABC.txt .
