Reso If multiple instances match, prefer the one whose cwd matches (or is a parent of) the project cwd passed in by the calling hook. +On **Windows** (issue #46) the addressable target is a named pipe (`\\.\pipe\nvim..0`) rather than a Unix socket. The [pidfile](#pidfile) is the primary path; the Unix glob fallbacks (steps 3–5) are replaced by a single **pipe-enumeration fallback** — list `\\.\pipe\`, keep names matching `nvim.*`, probe each for responsiveness. Pipe enumeration cannot run the cwd tiebreak (Windows has no `/proc` or `lsof` to read a process's cwd, and a pipe found this way has no pidfile cwd line), so it degrades to "first responsive pipe," mirroring how the Unix glob path degrades when the cwd lookup fails. The stale-pipe responsiveness probe (`nvim --server --remote-expr "1"`) is unchanged in shape; only the is-socket precheck is dropped (named pipes have no reliable existence test). + ## Pidfile One file per running Neovim that has called `code-preview.setup()`. Path: `${XDG_STATE_HOME:-$HOME/.local/state}/code-preview/sockets/`. Contents: line 1 is the RPC socket path, line 2 is the Neovim's cwd. Pidfiles self-register on `setup()`, refresh on `DirChanged`, and are removed on `VimLeavePre`. Crashed Neovims leave stale pidfiles behind; `socket discovery` self-heals by probing each socket with `--remote-expr "1"` before using it. +The pidfile *directory* is computed independently — and must agree byte-for-byte — on both the Lua writer (`pidfile.lua`) and the shim reader, so it can only use values both sides can derive without an RPC. On **Windows** (issue #46) that base is `%LOCALAPPDATA%\code-preview\sockets` (not the Unix `$XDG_STATE_HOME`/`$HOME` formula, which yields a driveless garbage path on Windows); line 1 of the file is the named-pipe path instead of a socket path. + The pidfile is *one of several* socket discovery paths, not a synonym for socket discovery. ## Hook entry The per-agent script the agent invokes directly when it's about to (or has just) used an editing tool. One pair per [integration](#integration): `code-preview-diff.sh` for pre-tool, `code-close-diff.sh` for post-tool.

The hook entry is **per-OS**: a `.sh` shim on Unix, a PowerShell `.ps1` shim on Windows (issue #46). PowerShell is the single Windows logic language across all agents — it is the only stock-Windows-11 tool that parses JSON natively, enumerates named pipes, and probes the RPC socket. The installer writes the interpreter explicitly into the agent's `command` field (`powershell -NoProfile -ExecutionPolicy Bypass -File .ps1`); a thin `.cmd` trampoline is added only for an agent that raw-execs a bare path and rejects a multi-token command.

Windows forces a second [socket discovery](../../CONTEXT.md#socket-discovery) implementation regardless of agent, because Windows nvim is addressed via a named pipe (`\\.\pipe\nvim..0`) and none of the Unix discovery tooling (`lsof`, `compgen`, `kill -0`, the `/var/folders`/`/tmp`/`$XDG_RUNTIME_DIR` globs) exists. We implement that second discovery+RPC layer **once, in PowerShell**, and have all four agents — claudecode, codex, copilot, *and* opencode — share it via a per-OS [hook entry](../../CONTEXT.md#hook-entry): a `.sh` shim on Unix, a `.ps1` shim on Windows. + +PowerShell (Windows PowerShell 5.1, in-box on every Windows 11) is the single Windows logic language: it is the only stock tool that parses JSON natively (replacing the Unix shims' `jq`), enumerates named pipes, and probes the RPC socket. The installer writes the interpreter explicitly into each agent's `command` field (`powershell -NoProfile -ExecutionPolicy Bypass -File .ps1`); a thin `.cmd` trampoline is added only for an agent whose `command` field turns out to raw-exec a bare path and reject a multi-token command. + +## Considered Options (OpenCode specifically) + +[ADR-0006](0006-opencode-defers-os-independence-to-46.md) deferred OpenCode's OS-independence to this issue, predicting OpenCode would be "among the first integrations to drop the bash dependency." This ADR **supersedes that prediction**: OpenCode does drop bash *on Windows*, but not by going shim-free — by switching to the shared PowerShell shim. + +- **A — OpenCode `execSync`s a per-OS shim** *(chosen)*. The TS plugin selects the `.sh` or `.ps1` shim by `process.platform`. Discovery logic lives only in the two per-OS shims, shared by all four agents. OpenCode adds zero new discovery code, and its Windows dependency improves from bash (not in-box) to PowerShell (in-box) — which is exactly the improvement ADR-0006's deferral was protecting. +- **B — TS-native `nvim --server` path, no shim.** OpenCode's hook entry is already a real language running in-process, so it *could* do discovery + RPC directly in TS. Rejected: this makes discovery a *third* implementation (bash + PowerShell + TS) that must track every change to the other two — precisely the divergence ADR-0006 was written to prevent, now made worse by the existence of the PowerShell impl. The fact that OpenCode *can* speak nvim directly does not mean it should own a private discovery implementation. +- **C — Full TS msgpack-rpc client.** Rejected in ADR-0006 (new runtime dependency, third protocol implementation); nothing in #46 changes that. + +## Consequences + +- The "one discovery implementation" principle becomes "one per **OS**" (bash + PowerShell), not one per agent. All four agents share both. This is the floor: Windows itself forces the second implementation, and we refuse to add a third. +- The Windows shim **never deserializes-and-reserializes the agent payload**. It parses only the shallow fields it needs (`cwd` for discovery, the tool name for the fast-path filter) with `ConvertFrom-Json`, and splices the raw stdin JSON *verbatim* into the RPC args array — exactly as the Unix shims' `jq --argjson` does. This sidesteps `ConvertTo-Json`'s default depth-2 truncation, which would otherwise silently drop deep MultiEdit/ApplyPatch structures. +- The tempfile path handed to the in-process [dispatcher](../../CONTEXT.md#dispatcher) is forward-slashed before being spliced into the `luaeval(...)` source string, because Windows backslashes are Lua escape sequences. The dispatcher (`rpc.lua`) itself is transport-agnostic and needs **no** changes — the payoff of the #47 phase-2/3 design. +- Two PowerShell 5.1 behaviours are validated by a spike before the shim is finalised: per-agent `command`-field invocation semantics (shell vs raw-exec, arguments accepted?), and native-command argument quoting of the `--remote-expr` value (5.1 lacks `PSNativeCommandArgumentPassing`).

Without it, `nvim --server X --remote-expr Y` starts a local TUI instead of acting as a pure remote client — stdout came back as terminal escape codes with no result, and the responsiveness probe exited 0 even against a dead pipe (false positive that would accept stale pidfiles). With --headless a dead server correctly yields exit 2. - nvim-call.ps1: eliminate double quotes from the --remote-expr value. PowerShell 5.1 lacks PSNativeCommandArgumentPassing and strips the embedded quotes in luaeval("..."), so nvim parsed require(...) as Vimscript -> E117. Switched to a single-quoted Vimscript body with Lua long-bracket [[...]] literals (zero quote chars to mangle); equally correct under pwsh 7. - pre_tool/init.lua: tmpdir() fell back to "/tmp" on Windows (no $TMPDIR there), so every diff tempfile write hit a nonexistent C:\tmp and the preview silently failed. Added a Windows branch (TMP/TEMP, forward- slashed); the Unix branch is left byte-identical. - log.lua: normalise the debug-log path with vim.fs.normalize so Windows no longer produces a mixed-separator string (...\nvim-data/code-preview.log). No-op on Unix; same physical file on Windows. Validated end-to-end: socket discovery, RPC round-trip, the claudecode shim opening a real preview, and live Claude Code edits across projects. Debug logging confirmed working identically to macOS.

From c85b64b6e4efc17f91646db311dade1ae04bc96f Mon Sep 17 00:00:00 2001 From: Cannon07 Date: Tue, 2 Jun 2026 09:51:33 +0530 Subject: [PATCH 12/12] fix: make checkhealth Windows-aware (#46) The Claude Code section checked the .sh shims for an executable bit, which on Windows means wrong artifact (the .ps1 are active) and ~6 spurious "not executable, run chmod +x" warnings (no exec bit on Windows; chmod is a no-op). - Add an OS-aware check_script helper: readability-only on Windows (the hook command invokes the interpreter explicitly), readability + exec bit on Unix. - Check the per-OS shim extension (.ps1 on Windows, .sh on Unix) for the Claude Code adapter scripts and the shared nvim-socket/nvim-call shims. - Gate the Codex/Copilot adapter-script checks behind not-Windows; on Windows emit one honest "not yet supported on Windows (#46)" line instead. Unix output unchanged (verified via headless checkhealth on macOS).
