Extended textDocument/definition and textDocument/typeDefinition handler that handles assembly/decompilation loading for $metadata$ documents.
By providing an alternate handler for textDocument/definition the plugin listens to all responses and if it receives URI with $metadata$ it will call custom omnisharp endpoint o#/metadata which returns full document source. This source is then loaded as a scratch buffer with name set to /$metadata$/... This allows then allows jumping to the buffer based on name or from quickfix list, because it's loaded.
csharpls use ILSpy/ICSharpCode.Decompiler to decompile code. So just get the uri and We can receive decompile sources from csahrpls
The api is "csharp/metadata", in neovim ,you can request it like
local result, err = client.request_sync("csharp/metadata", params, 10000, 0) -- 0 is for current buffer
You need to send a uri, it is like
csharp:/metadata/projects/trainning2/assemblies/System.Console/symbols/System.Console.cs
In neovim, it will be result(s) from vim.lsp.handles["textDocument/definition"]
and the key of uri is the key,
The key to send is like
local params = {
timeout = 5000,
textDocument = {
uri = uri,
}
}
The key of textDocument is needed. And timeout is just for neovim. It is the same if is expressed by json.
The object received is like
{
projectName = "csharp-test",
assemblyName = "System.Runtime",
symbolName = "System.String",
source = "using System.Buffers;\n ...."
}
And In neovim, You receive the "result" above, you can get the decompile source from
local result, err = client.request_sync("csharp/metadata", params, 10000, 0)
local source
if not err then
source = result.result.source
end
To use this plugin all that needs to be done is for the nvim lsp handler for textDocument/definition be overridden with one provided by this plugin.
If using lspconfig this can be done like this:
First configure omnisharp as per nvim-lspconfig.
Then to that config add handlers with custom handlers from this plugin.
local config = {
handlers = {
["textDocument/definition"] = require('csharpls_extended').handler,
["textDocument/typeDefinition"] = require('csharpls_extended').handler,
},
cmd = { csharpls },
-- rest of your settings
}
require'lspconfig'.csharp_ls.setup(config)
require'lspconfig'.csharp_ls.setup(config)
require("csharpls_extended").buf_read_cmd_bind()
require("telescope").load_extension("csharpls_definition")
