From e32462c6d56592acd22f1aab64f627636a476d6c Mon Sep 17 00:00:00 2001 From: Ville Penttinen Date: Tue, 19 Mar 2019 15:14:16 +0200 Subject: Improve filtering of file roots `ProjectWorkspace::to_roots` now returns a new `ProjectRoot` which contains information regarding whether or not the given path is part of the current workspace or an external dependency. This information can then be used in `ra_batch` and `ra_lsp_server` to implement more advanced filtering. This allows us to filter some unnecessary folders from external dependencies such as tests, examples and benches. --- crates/ra_lsp_server/src/lib.rs | 1 + crates/ra_lsp_server/src/server_world.rs | 34 +++--------------- crates/ra_lsp_server/src/vfs_filter.rs | 59 ++++++++++++++++++++++++++++++++ 3 files changed, 65 insertions(+), 29 deletions(-) create mode 100644 crates/ra_lsp_server/src/vfs_filter.rs (limited to 'crates/ra_lsp_server') diff --git a/crates/ra_lsp_server/src/lib.rs b/crates/ra_lsp_server/src/lib.rs index 59e16a47c..113883bdd 100644 --- a/crates/ra_lsp_server/src/lib.rs +++ b/crates/ra_lsp_server/src/lib.rs @@ -4,6 +4,7 @@ mod conv;
