Nodes in the 9P namespace can now declare alternate names (Aliases)
that resolve during Twalk but are invisible in directory listings.
Session dirs alias their immutable RunnableID(), agent dirs alias
their ID(). Clients can use session/{uuid}/agent/{uuid}/... paths
that remain valid across renames.
Changes:
- fs/fsnode.go: Add Aliases []string field, Alias() NodeOption
- fs/builder.go: findChild checks aliases via matchAlias helper
- fs/sessionfiles.go: Session dirs get Alias(s.RunnableID())
- fs/agentfiles.go: Agent dirs get Alias(a.ID())
- fs/spec.go: Add /aliases file (read-only alias→path table)
- fs/rootfiles.go: readAliases handler
- fs/lifecycle.go: buildIndex includes immutable ID in session/idx
- doc/edsl.md: Document Aliases field and behavior
- prompts: Update session/idx format documentation
The KDE GUI submodule now uses immutable IDs in all 9P paths,
fixing disconnected indicators after session rename.
ellie.el previously accessed ollie through a FUSE-mounted 9P
filesystem (plain file I/O via insert-file-contents/write-region).
This had several failure modes: stale mounts after suspend/resume,
no error propagation from 9P Rerror, no streaming support.
Now uses the ollie-9p CLI tool which speaks the 9P protocol
directly over the Unix socket. Also removed ellie-dired binding
(C-c C-d) and the ellie-mount-directory customization since
there is no mount point.
The completion subsystem was updated to use ollie-9p rdwr complete
instead of a shell pipeline to a 9P mount path.
With the zero-tools transition complete, the tools/builtin/ package
served no purpose — Builtins() returned nil. Removed:
- tools/builtin/builtins.go and the directory
- builtins field, WithBuiltins, Dispatch from toolsrv.Server
- Handler type from toolsrv (only used by builtins)
- OnPreDispatch/WithOnPreDispatch (dead code)
- Strict field and WithStrict (dead code, never read)
- CallTool simplified — no fallback to Dispatch
- builtin import and WithBuiltins/WithStrict calls from ollie-remote
- tools/builtin from justfile build/test targets
Updated AGENTS.md, ARCHITECTURE.md, README.md, EVOLUTION.md
Ollie's extensibility is the opposite of Emacs: instead of building
capabilities on top of an interpreter, the core provides integration
surfaces (9P, shell) and pushes everything else to the surrounding
system. This is the Acme/Plan 9 model.
The old fs/session/ package (14 files) and cmd/olliesrv/elevate_tree.go
(imperative FileTree implementations) are gone. Replaced by a single
declarative EDSL in fs/spec.go that declares the entire 9P namespace.
cmd/olliesrv/server.go simplified from 1430 to 825 lines:
- Deleted pathType() (110 lines) — tree.Stat() now handles all path resolution
- Deleted isSessionFile(), dirMode(), filePerm() — all from tree's info
- Deleted fsRoute/routes/route/routeDir — single rootTree, no route table
- Deleted elevateTree — EDSL handles /elevate/ in spec.go
- Deleted handleWrite(), readDNS(), helpPath() — dead code
- Deleted all 5 per-fid result fields — EDSL Request handlers manage state
- Deleted all path-based intercepts in read()/write() — entry.RequestRespMode()
- Deleted all path-depth hacks in makeStat() — custom Stat() closures in EDSL
- Deleted all content-length compute logic — info.Size() from tree
- Removed imports: agent, backend, elevate, paths, toolsrv, json
New fs/ package:
- spec.go — single EDSL declaration of the entire namespace
- builder.go — BuildTree() validates and compiles spec into *Tree
- tree.go — configurable FileTree implementation
- fsnode.go — Dir(), Leaf(), TemplateDir(), NodeOption constructors
- agentfiles.go / sessionfiles.go / rootfiles.go / elevatefiles.go
— handler implementations wired by the EDSL
- lifecycle.go — Create, Kill, Rename, Shutdown, InterruptAll
- persist.go, procfiles.go
- edsl.md — documentation of the EDSL
Tools no longer need to be co-located in $OLLIE_TOOLS_PATH. The .meta
sidecar can specify a cmd field pointing to any executable:
- Absolute path: use directly
- Bare name: resolve via $PATH
Resolution order: OLLIE_TOOLS_PATH/<name> → meta.cmd → PATH lookup.
Local wrappers always win, enabling simplified interfaces over complex
system binaries.
Rewrites doc/WRITING_TOOLS.md to document the plugin model: any
executable + .meta = tool, no source tree integration required.
These scripts were removed. Update all documentation to reference the
current alternatives: ollie-9p rdwr generate, ollie-9p rdwr complete,
and ollie-9p rdwr route.
