• Support highlighting references to the symbol under the cursor in the current file.
• Support loading external docsets from disk.

• Show the kind of thing being completed better.
• Add lints for unnecessary tset and do.

• Ignore unused locals if they end in underscore.
• Settings file: flsproject.fnl. Settings are now editor agnostic.
• Support :intersection as a Lua version; only includes globals present in every Lua.
• Support better completions. The eglot client is no longer a special case.

Changes

• Packaging scripts for nix and luarocks have been removed so they can be kept in downstream repositories.

Bug Fixes

• (set (. x y) z) wasn't being analyzed properly.
• (local {: unknown-field} (require :module)) lint warns about the unknown field when accessed via destructuring.

0.1.3 / 2024-06-27

Features

• Updated to fennel 1.5.0
• Better results when syntax errors are present
• Docs for each Lua version: 5.1 through 5.4
• Docs for TIC-80

Changes

• --check is now --lint

Bug Fixes

• Solved a case where there were duplicate completion candidates
• Special workaround for Eglot to be able to complete multisyms To be honest, this isn't even Eglot's fault; the LSP specification leaves it ambiguous Eglot's issue LSP's issue fennel-mode can't fix it on their end

Misc

• Switch json libraries from rxi/json.lua to dkjson
• Lots of refactoring and renaming things
• You can now build fennel-ls with no vendored dependencies if you want
• Building is more reproducible now! tools/get-deps.fnl will reproducibly get all the deps, instead of you needing to trust me
• faith updated to 0.2.0

0.1.2 / 2024-03-03

Features

• Completions and docs for coroutine, debug, io, math, os, string, table, utf8 and their fields.
• Global metadata can follow locals: With (local p print), looking up p will show print's information.
• New lint for erroneous calls to (values) that are in a position that would get truncated immediately.
• Upgrade to Fennel 1.4.2

Bug Fixes

• (-?> x) and similar macros no longer give a warning (even in fennel 1.4.1 before my -?> patch landed)
• Fixed off-by-one when measuring the cursor position on a multisym. For example, table|.insert (where | is the cursor) will correctly give information about table instead of insert.
• Can give completions in the contexts "(let [x " and "(if ", which previously failed to compile.
• Fields added to a table via (fn t.field [] ...) now properly appear in completions
• (include) is now treated like (require)

Misc

• Switched testing framework to faith
• Tests abstract out the filesystem
• Tests use the "|" character to mark the cursor, instead of manually specifying coordinates

0.1.1 / 2024-02-19

Features

• Add Nix(OS) support
• Add LuaRocks build support
• Upgrade to Fennel 1.4.1, the first release of fennel that is compatible with fennel-ls without patches.
• Added a lint for operators with no arguments, such as (+)
• textEdit field is present in completions

Bug Fixes

• Fix bug with renaming variables in method calls
• Lots of work to improve multival tracking
• --check gives a nonzero exit code when lints are found
