Is there a way to set the path using global variables?

[xarthurx]

I use Obsidian on Linux / Windows, and would like to use obsidian.nvim for the same.
While my obsidian baseDir is different on two different machines, I did sth like this:

if vim.loop.os_uname().sysname == "Windows_NT" then
  vim.g.obsidianDir = "~/source/docRepo/obDir/"
else 
  vim.g.obsidianDir = "~/winHome/source/docRepo/obDir/"
end 

However, when I set:

  workspaces = {
    {
      name = "personal",
      path = vim.g.obsidianDir,
    },

nvim will tell me the plugin cannot find that folder...

Is there a way to dynamically set the path variable?

obsidian.nvim/lua/obsidian/path.lua

Line 171 in 6661806

error "expected one argument"

I even tried this:

local workspacePaths = {
  linux = "~/source/docRepo/obBase",
  windows = "~/winHome/source/docRepo/obBase",
}

local function getWorkspacePath()
  local os = vim.loop.os_uname().sysname
  if os == "Linux" then
    return workspacePaths.linux
  elseif os == "Windows_NT" then
    return workspacePaths.windows
  else
    error("Unsupported operating system: " .. os)
  end
end

require("obsidian").setup({
  workspaces = {
    {
      name = "personal",
      path = getWorkspacePath(),
    },
  },
})

Still not working. It seems the path.lua is handling the string in a very strange way...

OK, I figured out:

local Path = require("plenary.path")

local workspacePaths = {
  windows = "~/source/docRepo/obBase",
  linux = "~/winHome/source/docRepo/obBase",
}

local function getWorkspacePath()
  local os = vim.loop.os_uname().sysname
  local path
  if os == "Linux" then
    path = workspacePaths.linux
  elseif os == "Windows_NT" then
    path = workspacePaths.windows
  else
    error("Unsupported operating system: " .. os)
  end
  return Path:new(path):expand()
end

But it is really good to allow direct assignment of vim global variables...
