Can't change file name capitalisation while renaming in the folder view

[Haagenti]

Summary

When working on a folder with Sublime, if I try to change the capitalisation of a file without changing the actual file name (e.g. capitalisation.txt to Capitalisation.txt), it says that the file already exists and it returns an error.

Expected behavior

it should rename the file correctly to the new capitalisation.

Actual behavior

The file isn't renamed and an "file already exists" error is returned

Steps to reproduce

1. Open a folder with files inside in Sublime through the "Open Folder" dialog
2. Right-click on a file
3. Choose "Rename..."
4. Change only the capitalisation of the file (e.g. capitalisation.txt to Capitalisation.txt)

Environment

• Operating system and version:
  • Windows 10
  • Mac OS ...
  • Linux ...
• Sublime Text:
  • Build 3103

Because Windows' filesystem (API?) is case-insensitive.

Maybe ST could rename the file into a random name before an actual renaming?

This bug exists on OSX as well with the default HFS+ options.

The fix is probably to check if the file that already exists is the same file that's being renamed.

+1. This issue would be great to have fixed. :)

This has been fixed in build 3133

I'm on build 3139 on Windows, and here's what happens for me:

1. main -> Main: nothing happens, the file remains lowercase main
2. main -> main2 -> Main: the file gets renamed as expected

Is this the intended behavior?

OMG, in my case is not working... Can't rename a file from server.php to Server.php with the last version of sublime, try it, download from the web page to Windows 10 64b

@keith-hall As its a windows file system problem and occurs from other applications too, like if we do "Save as" from Visual studio of some file. I am not getting how you fixed it.
Can you please help, i can't see myself as Sublime isn't open source.

@PalashBansal Unless a ST staff answer it here, no one knows how it's fixed. But isn't foo -> tmp_xxxxxxxxx -> Foo an easy solution?

Another note, I think here is NOT an official ST bug tracker but a community-driven one 😉

Thanks a lot @jfcherng for referencing the example.
Problem I am facing is because of using windows.h function GetSaveFileName which does all the work for me-

1. Opens the file save dialog
2. Takes the new file name
3. Ignores its case sensitiveness and asks to overwrite file
   and then just returns a bool value.
   While using this same windows API, not able to figure out solution to the problem.

@PalashBansal

Your situation is different from this issue (which is about renaming with ST's sidebar menu).

As for the "Save as..." (usually ctrl+shift+s in applications), I don't think ST fixes the case sensitiveness problem after my quick experiment (i.e., try to save foo.txt with Foo.txt). ST just open a save dialog like other applications (notepad++) do and the filename doesn't change after saving 😢

Thanks a lot @jfcherng for looking into, I don't need to install and try into ST now.
I was actually looking this for notepad++ only-
