An additional new line is being inserted (windows)

[JVApen]

Please describe the problem.

This is the issue described at xaverh/vscode-clang-format#84

Config:

IncludeBlocks: Regroup
SortIncludes: 'true'

The code:

#include "a.h"
#include "c.h"
#include "b.h"

using namespace NS;

Each time you format using clangd, a new line is added before the using namespace. I checked if I can remove the \r from the replacement in the formatting code, though it breaks other stuff while doing so. (clang-format.exe now reformats as it tries to remove the \r)

I couldn't find the code in the extension that applies these changes, though we'll have to remove the \r at the end (if it exists) before applying the replacement.

[HighCommander4]

I can't reproduce this on Linux, even after running the input file through unix2dos (so it has CRLF line endings).

Can you share a verbose clangd log?

I can't reproduce this on Linux, even after running the input file through unix2dos (so it has CRLF line endings).

I wouldn't be surprised to see that this is a Windows-only issue

[HighCommander4]

The log you shared doesn't include the didOpen message to show the state of the file before the formatting.

If possible, logs starting at clangd startup are ideal.

Thanks; I am able to reproduce the issue on Linux now, with an input file containing \r\n line endings.

Looking at the server's response to textDocument/formatting:

{
  "id": 8,
  "jsonrpc": "2.0",
  "result": [
    {
      "newText": "#include \"a.h\"\r\n#include \"b.h\"\r\n#include \"c.h\"\r",
      "range": {
        "end": {
          "character": 15,
          "line": 2
        },
        "start": {
          "character": 0,
          "line": 0
        }
      }
    }
  ]
}

The range to replace ends at line 2, character 15, which includes the \r on the line, but not the \n.

This certainly seems a bit odd (why include the \r but not the \n instead of both, or neither?), and might perhaps be interesting to investigate more deeply in clang-format internals... but on the other hand, the replacement text is consistent with this: it includes an \r, and not an \n at the end.

Naively, it seems to me that replacing a character range ending with \r with a new character sequence that also ends with \r should work? i.e. it seems to me that vscode is messing up this replacement somehow, inventing an additional \r\n pair from thin air.

I couldn't find the code in the extension that applies these changes,

The code that applies the formatting edits is not in vscode-clangd, but in vscode itself.

vscode-clangd includes the vscode-languageclient library, which implements the client-side handling of LSP protocol messages, and translates them to appropriate calls to the vscode extension API. For the textDocument/formatting feature, that happens around here in the vscode-languageclient source, but what that code does is not very interesting: it just converts the edits from the LSP representation to the vscode extension API representation.

The code that applies the edits is in vscode itself (in the repo https://github.com/microsoft/vscode); I haven't tracked it down, but a starting point to do so would be to find the implementation of the registerDocumentFormattingEditProvider API called here, and see how the implementation uses the formatting provider that's passed in.

I've checked the internals of clang-format and it simply doesn't care about \r, it considers is just a character in a line which starts with #include and shuffles it around. It happens to be the last character as it splits on \n

I've logged an issue with VS Code, we'll see when they fix it
