[This other video](https://www.youtube.com/watch?v=ydcrdwQKqI8) shows what the same experience looks like from Emacs. -Due to the editor-agnostic nature of the _DAP_ protocol, a very similar experience is delivered to users of a different developement tool, be it _Vim_, _VS Code_ or _Sublime Text 3_. +Due to the editor-agnostic nature of the _DAP_ protocol, a very similar experience is delivered to users of a different development tool, be it _Vim_, _VS Code_ or _Sublime Text 3_. ## Project Goal diff --git a/apps/els_core/include/els_core.hrl b/apps/els_core/include/els_core.hrl index 2ec182a12..2d142e2ea 100644 --- a/apps/els_core/include/els_core.hrl +++ b/apps/els_core/include/els_core.hrl @@ -207,7 +207,7 @@ }. %%------------------------------------------------------------------------------ -%% Document Fiter +%% Document Filter %%------------------------------------------------------------------------------ -type document_filter() :: #{ language => binary() , scheme => binary() diff --git a/apps/els_dap/src/els_dap_general_provider.erl b/apps/els_dap/src/els_dap_general_provider.erl index e1534e815..9a41d27c4 100644 --- a/apps/els_dap/src/els_dap_general_provider.erl +++ b/apps/els_dap/src/els_dap_general_provider.erl @@ -1,7 +1,7 @@ %%============================================================================== %% @doc Erlang DAP General Provider %% -%% Implements the logic for hanlding all of the commands in the protocol. +%% Implements the logic for handling all of the commands in the protocol. %% %% The functionality in this module will eventually be broken into several %% different providers. diff --git a/apps/els_dap/test/els_dap_general_provider_SUITE.erl b/apps/els_dap/test/els_dap_general_provider_SUITE.erl index 47f77d0fc..01c0c850c 100644 --- a/apps/els_dap/test/els_dap_general_provider_SUITE.erl +++ b/apps/els_dap/test/els_dap_general_provider_SUITE.erl @@ -291,7 +291,7 @@ frame_variables(Config) -> -spec navigation_and_frames(config()) -> ok. navigation_and_frames(Config) -> - %% test next, stepIn, continue and check aginst expeted stack frames + %% test next, stepIn, continue and check against expected stack frames Provider = ?config(provider, Config), #{<<"threads">> := [#{<<"id">> := ThreadId}]} = els_provider:handle_request( Provider diff --git a/apps/els_lsp/src/els_code_navigation.erl b/apps/els_lsp/src/els_code_navigation.erl index 988b8365f..d32eb324e 100644 --- a/apps/els_lsp/src/els_code_navigation.erl +++ b/apps/els_lsp/src/els_code_navigation.erl @@ -36,7 +36,7 @@ goto_definition( Uri [] -> {error, not_in_function_clause}; FunRanges -> FunRange = lists:last(FunRanges), - %% Find the first occurance of the variable in the function clause + %% Find the first occurrence of the variable in the function clause [POI|_] = [P || P = #{range := Range, id := Id} <- VarPOIs, els_range:compare(Range, VarRange), els_range:compare(FunRange, Range), @@ -61,7 +61,7 @@ goto_definition( Uri Kind =:= implicit_fun; Kind =:= export_entry -> %% try to find local function first - %% fall back to bif search if unsuccesful + %% fall back to bif search if unsuccessful case find(Uri, function, {F, A}) of {error, Error} -> case is_imported_bif(Uri, F, A) of diff --git a/apps/els_lsp/src/els_erlfmt_ast.erl b/apps/els_lsp/src/els_erlfmt_ast.erl index 0d92759ed..6c95b1a8d 100644 --- a/apps/els_lsp/src/els_erlfmt_ast.erl +++ b/apps/els_lsp/src/els_erlfmt_ast.erl @@ -321,7 +321,7 @@ erlfmt_to_st(Node) -> %% clauses of case/if/receive/try erlfmt_clause_to_st(Clause); %% Lists are represented as a `list` node instead of a chain of `cons` - %% and `nil` nodes, similar to the `tuple` node.

This change introduced a regression in the debugger, preventing it from starting. The `els_dap` escript invokes the `els_config` initialization procedure (see https://github.com/erlang-ls/erlang_ls/commit/4b475b0864f433ccc08c80609478f5b15b9b41b7), but the new version of the initialization depends on the `els_diagnostics` module, which is part of the `els_lsp` application, not included in the `els_dap` escript. For now simply reverting the change, but we should revisit the application structure. The original idea was for an application to contain the implementation of the JSON-RPC protocol and for the `els_dap` and `els_lsp` to utilize that as a dependency. That never really happened and the current application split in Erlang LS in its current form feels a bit arbitrary. One may argue that Erlang LS could get rid of the umbrella structure and be a single application. --- apps/els_core/src/els_config.erl | 1 - apps/els_lsp/src/els_diagnostics.erl | 2 +- 2 files changed, 1 insertion(+), 2 deletions(-) diff --git a/apps/els_core/src/els_config.erl b/apps/els_core/src/els_config.erl index b8fe0f39a..e295c715e 100644 --- a/apps/els_core/src/els_config.erl +++ b/apps/els_core/src/els_config.erl @@ -163,7 +163,6 @@ do_initialize(RootUri, Capabilities, InitOptions, {ConfigPath, Config}) -> ok = set(otp_paths , otp_paths(OtpPath, false) -- ExcludePaths), ok = set(lenses , Lenses), ok = set(diagnostics , Diagnostics), - ok = set(enabled_diagnostics, els_diagnostics:enabled_diagnostics()), %% All (including subdirs) paths used to search files with file:path_open/3 ok = set( search_paths , lists:append([ project_paths(RootPath, AppsDirs, true) diff --git a/apps/els_lsp/src/els_diagnostics.erl b/apps/els_lsp/src/els_diagnostics.erl index 3e288ee15..9c9b4b303 100644 --- a/apps/els_lsp/src/els_diagnostics.erl +++ b/apps/els_lsp/src/els_diagnostics.erl @@ -90,7 +90,7 @@ make_diagnostic(Range, Message, Severity, Source) -> -spec run_diagnostics(uri()) -> [pid()]. run_diagnostics(Uri) -> - [run_diagnostic(Uri, Id) || Id <- els_config:get(enabled_diagnostics)]. + [run_diagnostic(Uri, Id) || Id <- enabled_diagnostics()]. %%============================================================================== %% Internal Functions From a24f3e94161e724b6c83430358afedb12e0250d8 Mon Sep 17 00:00:00 2001 From: Roberto Aloi Date: Tue, 15 Feb 2022 12:55:52 +0100 Subject: [PATCH 023/239] Fix support for renaming modules (#1199) The textDocument parameter in a TextDocumentEdit must contain a version, even if null (see the OptionalVersionedTextDocumentIdentifier definition from the LSP specification).

Now that Gradualizer is a dependency of ErlangLS, it's running on each startup since ErlangLS itself. This means the check never succeeds, therefore the project specific files necessary for properly setting up the typechecker are never loaded. This leads to false positives being reported such as missing remote types or record definitions. Reimporting the project files on each run might be a bit redundant, but it seems to work reasonably well in practice. Dogfooding this solutions shows it doesn't lead to visible unnecessary load on the system. --- .../src/els_gradualizer_diagnostics.erl | 43 ++++++------------- 1 file changed, 14 insertions(+), 29

This was problematic, since requests handled by different providers could lead to race conditions, causing a server crash. For example, a completion request could not see the latest version of the text in case of incremental text synchronization. There was very little gain in parallelizing providers, so we decided to simplify the architecture and have a single process, instead. There's still room for refactoring and cleanup, but those will be handled as a follow up. As part of the architectural change, we also dropped support for BSP since it has been stalling for too long time. Instead, we will try to implement a simpler solution which allows the extraction of paths from the build system (e.g. via the rebar.conifg). * Drop BSP Support * Introduce text synchronization provider * Run providers as a single process * Remove buffer server, index in the background instead * Decouple DAP provider from LSP one * Brutally kill background jobs * Set standard_io as default value for the io_device --- apps/els_core/src/els_config.erl | 4 -

Finally, since it can now happen that, after a restart, the provider receives messages (results or diagnostics) by background jobs, ensure that such responses are handled correctly: results are propagated to the server (no change) while diagnostics are ignored. --- apps/els_core/src/els_provider.erl | 61 +++++++++++++++++++----------- apps/els_core/src/els_stdio.erl | 2 +- apps/els_lsp/src/els_sup.erl | 6 +-- 3 files changed, 43 insertions(+), 26 deletions(-) diff --git a/apps/els_core/src/els_provider.erl b/apps/els_core/src/els_provider.erl index 307d927ef..51ff7d280 100644 --- a/apps/els_core/src/els_provider.erl +++ b/apps/els_core/src/els_provider.erl @@ -13,6 +13,7 @@ , handle_call/3 , handle_cast/2 , handle_info/2 + , terminate/2 ]). %%============================================================================== @@ -93,6 +94,9 @@ cancel_request_by_uri(Uri) -> -spec init(unused) -> {ok, state()}. init(unused) -> + %% Ensure the terminate function is called on shutdown, allowing the + %% job to clean up. + process_flag(trap_exit, true), {ok, #{in_progress => [], in_progress_diagnostics => []}}. -spec handle_call(any(), {pid(), any()}, state()) -> @@ -150,28 +154,37 @@ handle_info({result, Result, Job}, State) -> handle_info({diagnostics, Diagnostics, Job}, State) -> #{in_progress_diagnostics := InProgress} = State, ?LOG_DEBUG("Received diagnostics [job=~p]", [Job]), - { #{ pending := Jobs - , diagnostics := OldDiagnostics - , uri := Uri - } - , Rest - } = find_entry(Job, InProgress), - NewDiagnostics = Diagnostics ++ OldDiagnostics, - els_diagnostics_provider:publish(Uri, NewDiagnostics), - NewState = case lists:delete(Job, Jobs) of - [] -> - State#{in_progress_diagnostics => Rest}; - Remaining -> - State#{in_progress_diagnostics => - [#{ pending => Remaining - , diagnostics => NewDiagnostics - , uri => Uri - }|Rest]} - end, - {noreply, NewState}; + case find_entry(Job, InProgress) of + {ok, { #{ pending := Jobs + , diagnostics := OldDiagnostics + , uri := Uri + } + , Rest + }} -> + NewDiagnostics = Diagnostics ++ OldDiagnostics, + els_diagnostics_provider:publish(Uri, NewDiagnostics), + NewState = case lists:delete(Job, Jobs) of + [] -> + State#{in_progress_diagnostics => Rest}; + Remaining -> + State#{in_progress_diagnostics => + [#{ pending => Remaining + , diagnostics => NewDiagnostics + , uri => Uri + }|Rest]} + end, + {noreply, NewState}; + {error, not_found} -> + {noreply, State} + end; handle_info(_Request, State) -> {noreply, State}. +-spec terminate(any(), state()) -> ok. +terminate(_Reason, #{in_progress := InProgress}) -> + [els_background_job:stop(Job) || {_Uri, Job} <- InProgress], + ok. + -spec available_providers() -> [provider()]. available_providers() -> [ els_completion_provider @@ -198,16 +211,20 @@ available_providers() -> %% Internal Functions %%============================================================================== -spec find_entry(job(), [diagnostic_entry()]) -> - {diagnostic_entry(), [diagnostic_entry()]}. + {ok, {diagnostic_entry(), [diagnostic_entry()]}} | + {error, not_found}. find_entry(Job, InProgress) -> find_entry(Job, InProgress, []). -spec find_entry(job(), [diagnostic_entry()], [diagnostic_entry()]) -> - {diagnostic_entry(), [diagnostic_entry()]}. + {ok, {diagnostic_entry(), [diagnostic_entry()]}} | + {error, not_found}. +find_entry(_Job, [], []) -> + {error, not_found}; find_entry(Job, [#{pending := Pending} = Entry|Rest], Acc) -> case lists:member(Job, Pending) of true -> - {Entry, Rest ++ Acc}; + {ok, {Entry, Rest ++ Acc}}; false -> find_entry(Job, Rest, [Entry|Acc]) end. diff --git a/apps/els_core/src/els_stdio.erl b/apps/els_core/src/els_stdio.erl index 50d16207b..b385a7089 100644 --- a/apps/els_core/src/els_stdio.erl +++ b/apps/els_core/src/els_stdio.erl @@ -22,7 +22,7 @@ start_listener(Cb) -> -spec init({function(), atom() | pid()}) -> no_return(). init({Cb, IoDevice}) -> - ?LOG_INFO("Starting stdio server..."), + ?LOG_INFO("Starting stdio server...

From cfab726faee04dc153f864da799ad8cb1cf53c71 Mon Sep 17 00:00:00 2001 From: Roberto Aloi Date: Tue, 10 May 2022 19:11:12 +0200 Subject: [PATCH 069/239] Track open files (#1292) * Track open files It can happen that some files are opened in the editor. If these files have pending changes (unsaved), we should consider them as the "source of truth" when it comes to text edits flowing from the IDE to the language server. In case of an external operation (e.g. a checkout or rebase in a version control system), Erlang LS inconditionally reloads changed files from disk. This is an incorrect behaviour, since subsequent operations applied via the IDE to a non up-to-date version of the buffer can result in errors. The language server should ignore such external operations when the file is opened in the editor. Eventual inconsistencies between the disk-copy and the IDE-copy of the file will be resolved in the context of the IDE (e.g. in VS Code the user is warned about the situation on save) and text edits from the IDE can always be trusted. --- apps/els_core/src/els_provider.erl | 7 ++- apps/els_lsp/src/els_methods.erl | 17 +++++-- apps/els_lsp/src/els_server.erl | 2 +-

Specifically, since `didChangeWatchedFiles` notifications are asynchronous, it can happen that a file is deleted before a notification is processed by the server. In such a case, the server should simply ignore the notification, since a new one will arrive. Also, there is no need to deeply index files during a rebase, so let's convert to a shallow indexing.

The whole detection algorithm could probably be revisited (it would be good to check if this problem has been tackled in literature), but for now this optimization will lower the execution time for "unused includes" diagnostics and reduce the stress on the language server, especially for big modules. As an example, this optimization reduces the computing time for "unused includes" diagnostics for the `els_parser.erl` module from ~1s to ~200ms. --- .../src/els_unused_includes_diagnostics.erl | 41 ++++++++++--------- 1 file changed, 22 insertions(+), 19 deletions(-) diff --git a/apps/els_lsp/src/els_unused_includes_diagnostics.erl b/apps/els_lsp/src/els_unused_includes_diagnostics.erl index f9810d976..e29c142a0 100644 --- a/apps/els_lsp/src/els_unused_includes_diagnostics.erl +++ b/apps/els_lsp/src/els_unused_includes_diagnostics.erl @@ -86,28 +86,31 @@ find_unused_includes(#{uri := Uri} = Document) -> els_config:get(exclude_unused_includes) ), IncludedUris = IncludedUris1 -- ExcludeUnusedIncludes, - Fun = fun(POI, Acc) -> - update_unused(Graph, Uri, POI, Acc) - end, - UnusedIncludes = lists:foldl(Fun, IncludedUris, POIs), + UnusedIncludes = update_unused(IncludedUris, Graph, Uri, POIs), digraph:delete(Graph), UnusedIncludes. --spec update_unused(digraph:graph(), uri(), els_poi:poi(), [uri()]) -> [uri()]. -update_unused(Graph, Uri, POI, Acc) -> - case els_code_navigation:goto_definition(Uri, POI) of - {ok, Uri, _DefinitionPOI} -> - Acc; - {ok, DefinitionUri, _DefinitionPOI} -> - case digraph:get_path(Graph, DefinitionUri, Uri) of - false -> - Acc; - Path -> - Acc -- Path - end; - {error, _Reason} -> - Acc - end. +-spec update_unused([uri()], digraph:graph(), uri(), [els_poi:poi()]) -> [uri()]. +update_unused(Acc = [], _Graph, _Uri, _POIs) -> + Acc; +update_unused(Acc, _Graph, _Uri, _POIs = []) -> + Acc; +update_unused(Acc, Graph, Uri, [POI | POIs]) -> + NewAcc = + case els_code_navigation:goto_definition(Uri, POI) of + {ok, DefinitionUri, _DefinitionPOI} when DefinitionUri =:= Uri -> + Acc; + {ok, DefinitionUri, _DefinitionPOI} -> + case digraph:get_path(Graph, DefinitionUri, Uri) of + false -> + Acc; + Path -> + Acc -- Path + end; + {error, _Reason} -> + Acc + end, + update_unused(NewAcc, Graph, Uri, POIs). -spec expand_includes(els_dt_document:item()) -> digraph:graph(). expand_includes(Document) -> From c74e3f735fa518ebf009b1b32c16dc179ee6e353 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?H=C3=A5kan=20Nilsson?= <haakan@gmail.com> Date: Mon, 13 Jun 2022 09:02:25 +0200 Subject: [PATCH 090/239] Consider argument of ifdef, ifndef, undef attributes to be a macro (#1327) --- apps/els_lsp/src/els_parser.erl | 8 ++++++++ apps/els_lsp/test/els_parser_SUITE.erl | 20 ++++++++++++++++++++ 2 files changed, 28 insertions(+) diff --git a/apps/els_lsp/src/els_parser.erl b/apps/els_lsp/src/els_parser.erl index 05d35ab84..19d42f930 100644 --- a/apps/els_lsp/src/els_parser.erl +++ b/apps/els_lsp/src/els_parser.erl @@ -429,6 +429,14 @@ attribute(Tree) -> undefined -> [poi(Pos, spec, undefined)] end; + {Attribute, [{Type, Anno, Name}]} when + (Attribute =:= ifdef orelse + Attribute =:= ifndef orelse + Attribute =:= undef), + (Type =:= var orelse + Type =:= atom) + -> + poi(Anno, macro, Name); _ -> [] catch diff --git a/apps/els_lsp/test/els_parser_SUITE.erl b/apps/els_lsp/test/els_parser_SUITE.erl index a6b151edc..896bd8f39 100644 --- a/apps/els_lsp/test/els_parser_SUITE.erl +++ b/apps/els_lsp/test/els_parser_SUITE.erl @@ -16,6 +16,9 @@ parse_incomplete_type/1, parse_no_tokens/1, define/1, + ifdef/1, + ifndef/1, + undef/1, underscore_macro/1, specs_with_record/1, types_with_record/1, @@ -203,6 +206,23 @@ define(_Config) -> els_parser:parse("-define(MACRO(A, B), A:B()).") ). +-spec ifdef(config()) -> ok. +ifdef(_Config) -> + Text = "-ifdef(FOO).", + ?assertMatch([#{id := 'FOO'}], parse_find_pois(Text, macro)), + Text2 = "-ifdef(foo).", + ?assertMatch([#{id := 'foo'}], parse_find_pois(Text2, macro)). + +-spec ifndef(config()) -> ok. +ifndef(_Config) -> + Text = "-ifndef(FOO).", + ?assertMatch([#{id := 'FOO'}], parse_find_pois(Text, macro)). + +-spec undef(config()) -> ok. +undef(_Config) -> + Text = "-undef(FOO).", + ?assertMatch([#{id := 'FOO'}], parse_find_pois(Text, macro)). + -spec underscore_macro(config()) -> ok. underscore_macro(_Config) -> ?assertMatch( From 550165e4b08b7094faf76941c7e552b05f470faf Mon Sep 17 00:00:00 2001 From: Michael Davis <mcarsondavis@gmail.com> Date: Mon, 13 Jun 2022 02:07:53 -0500 Subject: [PATCH 091/239] [#1300] Implement textDocument/signatureHelp.

From 3a8c4faddd2efdec4e42fc93fb75bc76f40daa99 Mon Sep 17 00:00:00 2001 From: Robin Morisset <RobinMorisset@users.noreply.github.com> Date: Mon, 13 Jun 2022 18:47:58 +0200 Subject: [PATCH 093/239] [#1205] Implement goto_definition for testcases. (#1330) * Implement goto_definition for testcases Summary: https://github.com/erlang-ls/erlang_ls/issues/1205 suggested supporting the goto-definition feature for testcases. Testcases are atoms (function definitions) and currently whenever doing goto-definition on an atom we treat it as a module. I simply modified goto_definition to first look for a function of arity 1 in the current module when it is unclear whether the user is looking for a module or a testcase. Test Plan: I added the "testcase" test-case in els_definition_SUITE, following the structure of all other test-cases in that file. This new testcase corresponds to doing "goto defintion" on the atom "one" which appears in "all() -> [ one ]" in sample_SUITE.erl. It verifies that we are sent to the definition of one at the bottom of sample_SUITE.erl. I then checked that this new test-case passed, and that I did not break any other test in that suite. In particular, there were already tests for goto-definition on module names, and they still pass.

(#1329) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Merge server and provider processes. The els_provide process is a remain from the times where providers had their own dedicated processes and it does not currently provide additional value. It actually makes provider errors not bubble up to the client. In fact, in case of a provider error the provider process would crash, but the server would indefinitely wait for a response. The error would not be returned via LSP. This change simplifies the architecture of Erlang LS by merging the els_server and els_provider processes: * Get rid of els_provider process and internal_state * Remove obsolete available_providers function * Do not pass server state to providers As a follow up, it should be possible to: * Pass requests as-they-are (as opposed to only the parameters) to providers, avoiding an un-necessary translation layer * Generalize the code in els_method * Update apps/els_core/src/els_provider.erl Co-authored-by: Michał Muskała <micmus@whatsapp.com> * Fix dialyzer spec Co-authored-by: Michał Muskała <micmus@whatsapp.com> --- apps/els_core/src/els_provider.erl | 245 +----------------- .../src/els_call_hierarchy_provider.erl | 19 +- apps/els_lsp/src/els_code_action_provider.erl | 8 +- apps/els_lsp/src/els_code_lens_provider.erl | 8 +- apps/els_lsp/src/els_completion_provider.erl | 8 +- apps/els_lsp/src/els_definition_provider.erl | 10 +- apps/els_lsp/src/els_diagnostics_provider.erl | 8 +- .../src/els_document_highlight_provider.erl | 11 +- .../src/els_document_symbol_provider.erl | 8 +- .../src/els_execute_command_provider.erl | 8 +- .../src/els_folding_range_provider.erl | 6 +- apps/els_lsp/src/els_formatting_provider.erl | 22 +- apps/els_lsp/src/els_general_provider.erl | 14 +- apps/els_lsp/src/els_hover_provider.erl | 8 +- .../src/els_implementation_provider.erl | 6 +- apps/els_lsp/src/els_methods.erl | 144 ++++++---- apps/els_lsp/src/els_references_provider.erl | 6 +- apps/els_lsp/src/els_rename_provider.erl | 6 +- apps/els_lsp/src/els_server.erl | 195 ++++++++++---- .../src/els_signature_help_provider.erl | 7 +- apps/els_lsp/src/els_sup.erl | 4 -

Tests have been updated to reflect these changes and new tests have been created to test the new options. --- apps/els_core/src/els_config_runtime.erl | 26 ++++++++- apps/els_core/src/els_distribution_server.erl | 11 +--- apps/els_core/src/els_utils.erl | 9 ++-- apps/els_dap/src/els_dap_general_provider.erl | 32 +++-------- apps/els_lsp/test/els_diagnostics_SUITE.erl | 54 +++++++++++++++---- 5 files changed, 84 insertions(+), 48 deletions(-) diff --git a/apps/els_core/src/els_config_runtime.erl b/apps/els_core/src/els_config_runtime.erl index 34dcbf5a5..bb3abfb8d 100644 --- a/apps/els_core/src/els_config_runtime.erl +++ b/apps/els_core/src/els_config_runtime.erl @@ -8,6 +8,8 @@ %% Getters -export([ get_node_name/0, + get_hostname/0, + get_domain/0, get_otp_path/0, get_start_cmd/0, get_start_args/0, @@ -20,6 +22,8 @@ -spec default_config() -> config(). default_config() -> #{ + "hostname" => default_hostname(), + "domain" => default_domain(), "node_name" => default_node_name(), "otp_path" => default_otp_path(), "start_cmd" => default_start_cmd(), @@ -31,6 +35,17 @@ get_node_name() -> Value = maps:get("node_name", els_config:get(runtime), default_node_name()), els_utils:compose_node_name(Value, get_name_type()). +-spec get_hostname() -> string(). +get_hostname() -> + case els_config:get(runtime) of + undefined -> default_hostname();

Following symlinks is necessary when using rebar3 checkout dependencies (erlang-ls/erlang_ls#1046) or when using Bazel (erlang-ls/erlang_ls#1064) since Bazel places dependencies and compiled files under its cache directory and symlinks the relevant directory in the cache to the workspace directory.

drive letter in a URI, then the compiler diagnostics end up sending the wrong position/range. This is because of this line. It checks that the path from the compiler matches the URI path. The path from the compiler has a lowercase drive letter, so they don't match and the diagnostics are treated as if they are coming from an include. I've fixed this in els_uri:path, but there might be a better place to do it, I'm not sure. --- apps/els_core/src/els_uri.erl | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) diff --git a/apps/els_core/src/els_uri.erl b/apps/els_core/src/els_uri.erl index feab6efc6..2c77f0458 100644 --- a/apps/els_core/src/els_uri.erl +++ b/apps/els_core/src/els_uri.erl @@ -49,9 +49,10 @@ path(Uri, IsWindows) -> case {IsWindows, Host} of {true, <<>>} -> % Windows drive letter, have to strip the initial slash - re:replace( + Path1 = re:replace( Path, "^/([a-zA-Z]:)(.*)", "\\1\\2", [{return, binary}] - ); + ), + lowercase_drive_letter(Path1); {true, _} -> <<"//", Host/binary, Path/binary>>; {false, <<>>} -> @@ -113,6 +114,13 @@ percent_decode(Str) -> http_uri:decode(Str). -endif. +-spec lowercase_drive_letter(binary()) -> binary(). +lowercase_drive_letter(<<Drive0, ":", Rest/binary>>) -> + Drive = string:to_lower(Drive0), + <<Drive, ":", Rest/binary>>; +lowercase_drive_letter(Path) -> + Path. + -ifdef(TEST). -include_lib("eunit/include/eunit.hrl").
