From a8c9e721d91efe4730db78c1115261fc128dca68 Mon Sep 17 00:00:00 2001 From: Mathias Fußenegger Date: Tue, 13 Sep 2022 22:16:20 +0200 Subject: feat(fs): extend fs.find to accept predicate (#20193) Makes it possible to use `vim.fs.find` to find files where only a substring is known. This is useful for `vim.lsp.start` to get the `root_dir` for languages where the project-file is only known by its extension, not by the full name. For example in .NET projects there is usually a `.csproj` file in the project root. Example: vim.fs.find(function(x) return vim.endswith(x, '.csproj') end, { upward = true }) --- test/functional/lua/fs_spec.lua | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) (limited to 'test/functional/lua') diff --git a/test/functional/lua/fs_spec.lua b/test/functional/lua/fs_spec.lua index 2bcc84db0f..3123ec324c 100644 --- a/test/functional/lua/fs_spec.lua +++ b/test/functional/lua/fs_spec.lua @@ -78,6 +78,23 @@ describe('vim.fs', function() return vim.fs.find(nvim, { path = dir, type = 'file' }) ]], test_build_dir, nvim_prog_basename)) end) + + it('accepts predicate as names', function() + eq({test_build_dir}, exec_lua([[ + local dir = ... + local opts = { path = dir, upward = true, type = 'directory' } + return vim.fs.find(function(x) return x == 'build' end, opts) + ]], nvim_dir)) + eq({nvim_prog}, exec_lua([[ + local dir, nvim = ... + return vim.fs.find(function(x) return x == nvim end, { path = dir, type = 'file' }) + ]], test_build_dir, nvim_prog_basename)) + eq({}, exec_lua([[ + local dir = ... + local opts = { path = dir, upward = true, type = 'directory' } + return vim.fs.find(function(x) return x == 'no-match' end, opts) + ]], nvim_dir)) + end) end) describe('normalize()', function() -- cgit
