[bug] conan remote command fails if remotes.json doen't exist about docs HOT 7 OPEN

Hi @leha-bot

Thanks for your report.
It seems there is something different there, I can't reproduce:

rm ..\..\.conan2\remotes.json && conan remote add local http://url.com && conan remote list
conancenter: https://center.conan.io [Verify SSL: True, Enabled: True]
local: http://url.com [Verify SSL: True, Enabled: True

works fine. Can you please try the above commands?

from docs.

I have discussed with the team, and yes, it seems a bit overkill at the moment
I am moving this to the docs, to clarify all files are utf-8 without bom headers. Thanks for the feedback!

Oh, it seems that the simple deletion is not sufficient to reproduce, I had had some another remotes (excluding conancenter) in that remotes.json, and conancenter was explicitly excluded (for test purposes on internal infra), seems this is a important detail for this, would try to reproduce it again...

from docs.

I am afraid I can't reproduce with that info either. Trying to add, remove, etc, doesn't make it fail like that.

I think the key is here: json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

This only happens if the json file is corrupted and not valid json. Maybe your remotes.json was broken? Someone accidentally touched it? If not, can you please try to provide steps to reproduce the error? Thanks!

Hi @leha-bot

Any feedback here? Thanks!

hello, sorry for late responce. It seems that the weird symbol was from PowerShell 'New-Item' (but I'm not sure). From my friends I heard that Powershell sometimes likes to add the Unicode BOM symbol in generated files (e.g., after pipelining like someprog > my.txt)

I think that if you have any resources, then it would be good to add the 'fool check' for weird BOM/file size (I saw some similar in YouCompleteMe Vim plugin for LSP: https://github.com/ycm-core/ycmd/pull/1680/files)

No prob, thanks for following up :)

I see. In general this fie is managed with the conan remote command, it makes sense now the behavior if powershell is adding extra characters unexpected. I also think that not only the characters, but also the encoding might be different.

Seems a bit overkill at the moment, the check adds some complexity and cost too, I'll check with the team for more opinions.
