Error: I cannot find the root of the current workspace/project.
If you would like to create a new dune project, you can type:
dune init project NAME
Otherwise, please make sure to run dune inside an existing project or
workspace. For more information about how dune identifies the root of the
current workspace/project, please refer to
https://dune.readthedocs.io/en/stable/usage.html#finding-the-root
I've identified the issue. Let me create a comprehensive plan:
The errors occur because:
Root Cause: The LSP configuration in /home/jm/.config/nvim/lsp/ocamllsp.lua:36-41 uses:
cmd = { 'dune', 'tools', 'exec', 'ocamllsp' }
When Neovim's LSP system tries to enable the server, it adds standard LSP flags (--stdio, --fallback-read-dot-merlin) to this command. These flags are being passed to dune instead of ocamllsp, causing:
dune: unknown option '--fallback-read-dot-merlin'dune: unknown option '--stdio'Why the current setup fails:
dune tools exec ocamllsp is a wrapper commandocamllsp, not duneChange the LSP configuration to call ocamllsp directly using the full path from ~/.opam/default/bin/ocamllsp.
/home/jm/.config/nvim/lsp/ocamllsp.lua:36-41cmd array to call ocamllsp directly~/.opam/default/bin/ocamllspOption A (Recommended): Use full path to opam's ocamllsp
cmd = { '/home/jm/.opam/default/bin/ocamllsp' }
Option B: Use a resolver function to dynamically find ocamllsp in PATH or opam
cmd = function()
local opam_path = '/home/jm/.opam/default/bin/ocamllsp'
if vim.fn.executable(opam_path) == 1 then
return { opam_path }
end
return { 'ocamllsp' }
end
Option C: Add opam bin directory to PATH and use just 'ocamllsp'
Which approach would you prefer?
dune in path is in my _opam local switch dir.
How should I configure my environment for pure dune package management as described by skills
I need to understand your current setup better and what "skills" you're referring to. Let me investigate your environment configuration.

00020| - **Single file** for all basic LSP setup
00021| - **Universal keymaps** applied to all servers
00022| - **Declarative server configs** using `vim.lsp.config`
00023| - **Automatic server enabling** with `vim.lsp.enable`
00024|
00025| ### Advanced Configuration (lsp/advanced.lua)
00026| - **Environment-aware** server startup (opam switches, virtual envs)
00027| - **Dynamic command resolution** based on project context
00028| - **Tool integration** (dune-dev, merlin, etc.)
00029| - **Version management** support (rustup, nvm, etc.)
00030|
00031| ### Environment Utilities (lsp/env.lua)
00032| - **Reusable functions** for environment detection
00033| - **Multi-language support** (OCaml, Python, Rust, Node.js)
00034| - **Project-aware** tool resolution
00035|
00036| ## Usage

00001| # LSP & Completion Configuration Analysis
00002|
00003| **Date:** November 3, 2025
00004| **Focus:** Improving completion relevance and reducing noise
00005|
00006| ---
00007|
00008| ## Executive Summary
00009|
00010| Your current setup uses:
00011| - **blink.cmp** for completion (modern, fast)
00012| - **Neovim 0.11+ vim.lsp.config API** (native, clean)
00013| - Multiple LSP servers: lua_ls, ocamllsp, gopls, ts_ls, ruff
00014|
00015| ### Key Issues Identified
00016|
00017| 1. **Completion Noise**: Default LSP settings often return too many irrelevant results
00018| 2. **Insufficient Filtering**: blink.cmp sources lack granular filtering
00019| 3. **Suboptimal Scoring**: Score offsets and max_items need tuning per-language
00020| 4. **Missing Capabilities Configuration**: Client capabilities not optimized for each server
00021|
00022| ---
00023|
00024| ## Current Configuration Review
00025|
00026| ### blink.cmp Setup (`lua/plugins/cmp.lua`)
00027|
00028| **Strengths:**
00029| - ✅ Good basic structure with proper source ordering
00030| - ✅ Score offsets prioritize LSP (offset: 10)
00031| - ✅ Fuzzy matching enabled with frecency
00032| - ✅ Reasonable max_items limits
00033|
00034| **Issues:**
00035| - ❌ Buffer source too aggressive (max_items: 30)
00036| - ❌ No per-language source configuration
00037| - ❌ Missing `transform_items` for filtering LSP results
00038| - ❌ `min_keyword_length = 1` may trigger too early
00039| - ❌ No completion kind filtering
00040|
00041| ### LSP Configuration (`lua/lsp/init.lua`, `/lsp/`)
00042|
00043| **Strengths:**
00044| - ✅ Clean separation of server configs
00045| - ✅ Environment-aware setup (opam, venv detection)
00046| - ✅ Proper use of vim.lsp.config API
00047|
00048| **Issues:**
00049| - ❌ Generic capabilities for all servers (no per-server tuning)
00050| - ❌ Missing completion-specific settings in server configs
00051| - ❌ No semantic token configuration
00052| - ❌ Language-specific completion prefer...Title: Setting Up Package Management With Dune

](https://github.com/secu...Perfect! Now I have all the context. Let me present a comprehensive plan for configuring your Neovim environment for pure Dune package management.
Based on the documentation I've reviewed, Dune Package Management (available in Dune 3.21+) provides:
dune tools install ocamllsp installs tools project-locallyeval $(dune tools env) sets up PATH to use project-local toolsYour LSP configuration uses:
cmd = { 'dune', 'tools', 'exec', 'ocamllsp' }
This fails because Neovim's LSP system adds flags (--stdio, --fallback-read-dot-merlin) to this command, and these flags get passed to dune instead of ocamllsp.
For pure Dune package management workflow:
Install ocamllsp project-locally:
dune tools install ocamllsp
Set up environment before launching Neovim:
eval $(dune tools env) in your shell.envrc:eval $(dune tools env)
Update LSP configuration (/home/jm/.config/nvim/lsp/ocamllsp.lua):
cmd = { 'ocamllsp' } -- Dune tools env adds it to PATH
Advantages:
For traditional opam workflow:
Ensure ocamllsp is in your opam switch:
opam install ocaml-lsp-server
Update LSP configuration to call ocamllsp directly:
cmd = { '/home/jm/.opam/default/bin/ocamllsp' }
-- or use a resolver function to find in PATH
Remove the problematic dune tools exec ocamllsp wrapper
Use opam for tools, Dune for dependencies:
Please let me know:
Do you want to adopt pure Dune package management (Option A)?
dune tools install ocamllsp + environment setupDo you want to stick with traditional opam (Option B)?
Or do you want a mixed approach (Option C)?
Also, please confirm:
Once you decide, I'll provide the exact implementation plan and file changes needed.
Option A
3.21 version of dune
Perfect! Dune 3.21 fully supports package management. Let me create a comprehensive implementation plan for Option A: Pure Dune Package Management.

</file>Now I have all the information needed. Here's my comprehensive implementation plan for Option A: Pure Dune Package Management:
Transition from opam-based tool management to pure Dune package management for OCaml development. This involves:
Current State:
~/.opam/default/bin/dune/usr/bin/direnv~/.bashrcRequirements for Dune Package Management:
File: ~/.bashrc
Change 1.1: Add direnv hook to bashrc
# Add after line 38 (after opam configuration section)
eval "$(direnv hook bash)"
Purpose: Enable direnv to automatically load/unload environment variables when entering/leaving directories.
Why: Allows automatic eval $(dune tools env) when entering Dune project directories.
File: /home/jm/.config/nvim/lsp/ocamllsp.lua
Change 2.1: Simplify cmd to use ocamllsp directly (lines 36-41)
From:
cmd = {
'dune',
'tools',
'exec',
'ocamllsp',
},
To:
cmd = { 'ocamllsp' },
Why:
--stdio, --fallback-read-dot-merlin passed to dune)eval $(dune tools env) is run, ocamllsp will be added to PATHChange 2.2: Keep all other configuration unchanged
cmd_env settings (OCAMLLSP_SEMANTIC_HIGHLIGHTING, DUNE_BUILD_DIR)filetypes configurationsettings and on_attach callbacksWhy: These settings work correctly and should be preserved.
Action 3.1: Create a minimal test OCaml project using Dune package management
Location: /home/jm/data/code/test-ocaml-dune/
Files to create:
dune-project
(lang dune 3.21)
(name test_project)
(package
(name test_project)
(depends
(ocaml (>= 4.14))))
test.ml
let greeting = "Hello, Dune Package Management!"
let () =
Format.printf "%s\n" greeting
dune
(executable
(public_name test)
(name test))
Action 3.2: Lock and install dependencies
cd /home/jm/data/code/test-ocaml-dune
dune pkg lock
Action 3.3: Install ocamllsp project-locally
dune tools install ocamllsp
What this does:
_build/.dune-tools/...)File: /home/jm/data/code/test-ocaml-dune/.envrc
Create new file:
#!/bin/bash
# Dune package management environment
eval $(dune tools env)
Action 4.1: Make file executable
chmod +x /home/jm/data/code/test-ocaml-dune/.envrc
Action 4.2: Allow direnv to load the configuration
cd /home/jm/data/code/test-ocaml-dune
direnv allow
What this does:
cd into the project directory, direnv automatically runs eval $(dune tools env)Test 5.1: Verify environment setup
cd /home/jm/data/code/test-ocaml-dune
which ocamllsp
# Expected: /home/jm/data/code/test-ocaml-dune/_build/.dune-tools/.../ocamllsp
Test 5.2: Test Neovim LSP startup
cd /home/jm/data/code/test-ocaml-dune
nvim test.ml
Expected results:
--fallback-read-dot-merlin or --stdio:LspInfo shows ocamllsp runningTest 5.3: Build and run the test program
cd /home/jm/data/code/test-ocaml-dune
dune build
dune exec ./test.exe
# Expected: Hello, Dune Package Management!
For any new or existing OCaml project using Dune package management:
Check project's dune-project file has (lang dune 3.21) or higher.
dune pkg lock
dune tools install ocamllsp
echo 'eval $(dune tools env)' > .envrc
chmod +x .envrc
direnv allow
nvim your_file.ml
dune.lock/Issue 1: direnv not loading
ocamllsp not found when running which ocamllspsource ~/.bashrcIssue 2: LSP still fails after changes
:LspRestart in Neovim:LspInfo to verify server is runningIssue 3: Multiple Dune versions
~/.opam/default/bin/dune is in PATH before /usr/bin/dune~/.bashrc before the opam configuration section:export PATH="/home/jm/.opam/default/bin:$PATH"
If this approach doesn't work:
Option 1: Revert to opam-based setup
cmd = { '/home/jm/.opam/default/bin/ocamllsp' }opam switch defaultopam install ocaml-lsp-serverOption 2: Mixed approach
| File | Purpose | Lines to Change |
|---|---|---|
~/.bashrc |
Add direnv hook | Add 1 line after line 38 |
/home/jm/.config/nvim/lsp/ocamllsp.lua |
Fix LSP cmd | Lines 36-41 |
| File | Purpose |
|---|---|

Test OCaml source |
/home/jm/data/code/test-ocaml-dune/dune |
Test build config |
/home/jm/data/code/test-ocaml-dune/.envrc |
Direnv environment config |
Should I create the test project in /home/jm/data/code/test-ocaml-dune or do you have a preferred location?
Do you want to add the opam default bin directory to PATH before the opam configuration in bashrc to ensure Dune 3.21.0 is always used?
Should I update the AGENTS.md file to document this new workflow for future reference?
Do you have any existing OCaml projects that should be converted to use this workflow? (I can provide conversion steps)
Once you confirm, I'll proceed with implementation.
