No changes yet

v0.7.2

We've identified several long-standing performance bottlenecks in Lexical. Among them:

1. A bottleneck that affects Lexical when it receives a large number of document updates. The bottleneck would cause the server process's Task Queue (the thing that delegates incoming LS requests to the process that handles them) to crash, and the server would become unusable after. Additionally, Lexical would build your code while the document updates were occurring, which would further slow things down. Both issues are now fixed, and Lexical waits until you stop making changes before it tries to compile your project.
2. We calculated the completion context once per completion item returned, which would be slow when a large number of completions were returned (like when you type Enum.). Since the context is static to your cursor, we only need to calculate it once.
3. Only call mix deps.compile for older versions of elixir that change the directory when compiling.
4. Incorporated Jose's new mix format task that doesn't require us to be inside of the given mix project. This means that formatting no longer uses the build lock. Formatting times have gone down from 400ms in the worst case to 10ms.

In addition, we've improved diagnostic reporting in config files.

v0.7

We're releasing 0.7 so we can support Elixir 1.17 and Erlang 27. However, those users on Erlang 27 will experience large increases in the amount of memory Lexical takes up due to this bug. When that bug is fixed, we'll push out another release that will detect the newer version of Erlang and things should go back to normal.

Other than supporting the newer versions of Erlang and Elixir, we've added the following features:

Features

• Organize aliases code action. When invoked, will alphabetize and flatten all your existing aliases in a module. It will also put all aliases in the same place in a module.
• Remove unused alias code action
• Add alias code action: Type a module, invoke the code action and see a list of modules to alias, select one, and it's added to your module's other aliases.
• Improved script handling: Now lexical won't execute scripts when editing them. Thanks, @zachallaun!
• We now show typespecs for struct field completions. Thanks @kirillrogovoy

• Don't evaluate top-level code in exs fils by @zachallaun #798
• Completion: Don't insert impl attribute if it's already present by @zachallaun #801
• Completion: Use existing specs to infer function signatures and vice-versa by @zachallaun #802

• Added struct definition detection for ecto schemas by @scohen in #758
• Sorted bang functions after non-bang variants by @scohen in #770

v0.6.1

Small bugfix release. We found an issue regarding unicode conversion, and although it's existed for a while and no one complained, we felt that it was more likely to happen now that we have workspace symbols.

• Fix conversion of UTF-8 positions to UTF-16 code units by @zachallaun in #719
• Fix Entity.resolve not correctly resolving local function capture calls @scottming in #721

v0.6.0 24 April, 2024

After multiple people asked, both document and workspace symbols have been implemented. Both make heavy use of our indexing infrastructure, which provides extremely fast and accurate results.

We've also fixed a number of small inconsistencies and crashes in the indexer, making it more robust and accurate. I especially want to call out the fix that @lukad made, that improved indexing performance by 3600x on his large codebase. When you update to this release, we strongly recommend re-indexing your project's source code by opening the project's mix.exs file and running the Rebuild <your project>'s code search index code action.

In addition, we've improved support for completions in phoenix controllers, stopped completions inside strings and have changed how we sort completions. The new sorting scheme is a big improvement for usability, and sorts things by how "close" they are to what you're working on. Give it a shot, we think you'll like it.

I'd like to thank all our new contributors, and especially our core team of @scottming, @zachallaun, @moosieus and @blond. You've all gone above and beyond.

v0.5.2 29 February, 2024

This is a bugfix release that fixes the following:

• Updated credo by @scohen in #617
• Update nix hash with new deps by @hauleth in #618
• Prepare scripts for updating Nix hash by non-Nix users by @hauleth in #619
• Update the installation documentation for the supported Elixir version by @scottming in #624
• Fixed unused variable code action by @scohen in #628

v0.5.1 22 February, 2024

This is a bugfix release that fixes an issue where lexical wouldn't start on MacOS if you're using the default bash, and not using one of the supported version managers (asdf, rtx or mise)

v0.5.0 21 February, 2024

Admittedly, it's been a long while since the last release, but we've laid the groundwork for some exciting new features.

Since November, we've built out our search and indexing infrastructure that allows lexical to find interesting bits of your source code and highlight them for you later. We went through five separate backends before settling on one that is super duper fast, memory efficient(ish) and is written in pure elixir.

Presently, we're using this to power our newest features, find references and go to definition. We've implemented both for modules, module attributes and functions. You'll notice that when lexical starts, it will index your project's source code. This is a one-time operation that should be quick, indexing lexical's and its dependencies 193,000 lines of source code takes around 10 seconds. This means that indexing is on by default, and there's no way to turn it off any more. We've crossed the rubicon, folks, and there's no turning back.

Other good news, because of the indexing infrastructure, we no longer have to do a full build when lexical starts for the first time. This means the startup time has dramatically improved. On the lexical project, it has dropped from 12 seconds to 2.

I'd like to thank @scottming @zachallaun and @Blond11516 for ensuring that the current state of the code is where it is today. Also, thank you @hauleth for taking care of the nix flake.

And we've made a ton of bug fixes and usability improvements since 0.4.1 as well. Some highlights include:

• Support for elixir version 1.16
• Handled renaming of rtx to mise
• Multiple improvements to the hover popup
• Improved ease of writing new code actions
• Undefined variables diagnostics error for HEEx templates
• Code action: Suggested function names
• Completions for typespecs

• Fix: Stutter when completing some items inside strings (:erl would complete to :erlerlang)
• Fix: Undefined variable names in HEEX templates
• Fix: Erlang remote calls in pipelines did not have their first parameter removed during completion
• Feature: Function names in completions are ordered by name and then arity

v0.4.0 24 October, 2023

Welcome to Lexical v0.4.0

The main thrust of v0.4 is hover support and quality of life improvements. Now, when you hover over a module or function, you'll see relevant documentation, types and parameters. We've also spent a lot of time working on completions in #410, which makes them more consistent, fixes some bugs in certain language clients (like eglot adding an extra @ when completing module attributes), and greatly improves their feel in vscode.

Additionally, quite a few of the changes in this PR were about laying the groundwork for our indexing infrastructure, which will debut in the next version. But fear not, this version has indexing disabled.

I want to thank @zachallaun and @scottming for all their hard work on this release. They've made lexical faster, more friendly and have removed a bunch of bugs!

Highlights include:

• Document hover for functions and modules
• Improved boot scripts
• Automatically updating nix flake. Thanks, @hauleth
• Helix editor integration. Thanks @philipgiuliani
• .heex integration
• Massively improved completions (Check out the PR, it's too big to summarize)

Bugs fixed:

• Longstanding unicode completion / editing bugs slain. Unicode works perfectly now.

Full Changelog: https://github.com/lexical-lsp/lexical/compare/v0.3.3...v0.4.0

v0.3.3 05 September, 2023

Fixed Unicode handling.

Unicode was likely broken under the last several releases; Unicode in documents would result in incorrect errors popping up. This has been fixed, and was due to incorrect decoding in the standard input handler.

Full Changelog: https://github.com/lexical-lsp/lexical/compare/v0.3.2...v0.3.3

v0.3.2 29 August, 2023

0.3.2 fixes a bug where packaging would not produce namespaced artifacts if the lexical directory was inside a subdirectory that had one of its dependencies as a path element.

For example, packaging would fail if lexical was in /path/to/home/language_servers/lexical.

Full Changelog: https://github.com/lexical-lsp/lexical/compare/v0.3.1...v0.3.2

v0.3.1 24 August, 2023

This is a bugfix release. Packaging generated in v0.3.0 would not start in directories that contain spaces, and this is the default for vscode under macOS. This release has a new launching mechanism that should allow us to use a lot less bash scripting.

v0.3.0 23 August, 2023
