Mathias Fußenegger e7cd811567 fix(lsp): handle negative activeSignature in signatureHelp (#17064)
omnisharp-roslyn can send negative values:

    {
      activeParameter = 0,
      activeSignature = -1,
      signatures = { {
          documentation = "",
          label = "TestEntity.TestEntity()",
          parameters = {}
        } }
    }

In 3.16 of the specification `activeSignature` is defined as `uinteger`
and therefore negative values shouldn't be allowed, but within 3.15 it
was defined as `number` which makes me think we can be a bit lenient in
this case and handle them.

The expected behavior is quite clear:

    The active signature. If omitted or the value lies outside the
    range of `signatures` the value defaults to zero or is ignored if
    the `SignatureHelp` has no signatures.

Fixes an error:

    util.lua:1685: attempt to get length of local 'lines' (a nil value)
    util.lua:1685: in function 'trim_empty_lines'
    handlers.lua:334: in function 'textDocument/signatureHelp'

See the Introduction wiki page and Roadmap for more information.

Features

See :help nvim-features for the full list!

Install from package

Pre-built packages for Windows, macOS, and Linux are found on the Releases page.

Managed packages are in Homebrew, Debian, Ubuntu, Fedora, Arch Linux, Void Linux, Gentoo, and more!

Install from source

See the Building Neovim wiki page for details.

The build is CMake-based, but a Makefile is provided as a convenience. After installing the dependencies, run the following command.

make CMAKE_BUILD_TYPE=RelWithDebInfo
sudo make install

To install to a non-default location:

make CMAKE_INSTALL_PREFIX=/full/path/
make install

CMake hints for inspecting the build:

  • cmake --build build --target help lists all build targets.
  • build/CMakeCache.txt (or cmake -LAH build/) contains the resolved values of all CMake variables.
  • build/compile_commands.json shows the full compiler invocations for each translation unit.

Transitioning from Vim

See :help nvim-from-vim for instructions.
