- `available_providers` holds the static enum tag names; drop the dupe
loop, its errdefer and the per-string frees.
- `reconcileModel` returns `error.ModelNotAvailable` directly instead of
a `use`/`abort` union the caller only mapped to that same error.
- `runCommand`/`printCommandResult` take `Command.ToolCall`; the caller
already has it, so the unreachable "no tool mapping" branches go.
- `handleSave` reuses `rememberSavePath`, which now propagates its
allocation failure so a first save under OOM warns instead of
unwrapping a null `save_path`.
- `SlashCommand.all_names` is a comptime `++` of the three name lists.
- `buildUserMessageParts` reads the attachment once for both text and
image, and prepends the text part instead of copying the list.
- `printSeverity`/`formatBulletLine` use `allocPrint` and the shared
`emitStderr`; drop an unreachable `ends_ws` check in `renderMetaHint`.
In a REPL whose stderr isn't a tty the spinner is disabled, so
`agentToolDone`'s `emitAbove` returned false and the `● [tool: …]` line
was discarded. `printToolOutcome` already fell back to a raw stderr write
in that case; share that fallback through `emitStderr`.
The non-REPL result line sliced `text` at a byte offset, which could
split a multi-byte codepoint and emit garbage. Truncate on a UTF-8
boundary instead.
Every data command went through printAssistant, so /markdown was styled by
accident while /tree, /getUrl and /evaluate strings had `*`/`_` eaten as
emphasis, and /markdown lost table alignment past Stream's 16 KiB buffer.
- printData renders only markdown as markdown; JSON is re-indented and the
rest prints verbatim.
- render iterates the source directly and aligns tables from the slice;
Fence holds the fence state shared with Stream.
- Links are OSC 8 hyperlinks around the label only, with the label
inline-rendered; `` drops the `!`; escapes follow CommonMark
so what the page dumper escapes is unescaped.
Zig 0.17 removes @cImport in favor of translate-c steps in the build
system. Each library's link function now creates an addTranslateC step
exposed as a module import: curl and isocline translate their headers
straight from the dependency tree, while sqlite3 uses the artifact's
emitted include tree since the amalgamation lives in a sub-dependency.
Terminal.zig and prompt_assist.zig previously instantiated two
independent @cImport namespaces for isocline; they now share one
translated module, so its types are identical across both files.
Built against https://github.com/lightpanda-io/zig-v8-fork/tree/zig-0.16 but
it doesn't require a new v8 build.
Built against https://github.com/lightpanda-io/boringssl-zig/tree/zig-0.16
since the current fork we point to isn't updated.
A global std.Io instance, lp.io. Way easier this way and requires 0 changes to
our libcurl integration / event loop.
Network code uses a new layer that does what Zig 0.15's posix package used to
do. Again, quicker migration that way. But, as long as we have the global IO,
and given the half-baked nature of networking in std.Io 0.16, this just makes
sense. Things can be migrated as needed.
The std.time.* -> std.Io.Timestamp/Clock/Duration resulted in _a lot_ of
changes. ArrayList = .{} -> ArrayList -> .empty also resulted in a lot of
changes, but that's obviously superficial. As is the trimLeft/trimRight ->
trimStart/trimEnd rename.
Locking adopt the `Uncancelable` variants, e.g. mutex.lockUncancelable() to
preserve the error-free signature (and, because cancellation would be something
we'd have to put more thought into).
std.json.ObjectMap is now unmanaged, so the allocator had to be passed along.
However, there's still a deprecated managed variant of MemoryPool, so I switched
to it (we can do a small follow up PR to move to the unmanaged after).
I tried use_llvm = false, but it locks my computer, consuming RAM until MacOS
gives me a popup I've never seen before, begging me to start killing processes.
Agent and the networking stuff saw the most significant changes.
- attachCompleter now takes the CompletionSource: Agent no longer
reaches through terminal.assist to configure what it just attached,
and attach/configure can't be sequenced wrong.
- history_paths flows through one channel: attach() loads the initial
history from the same State field modeCallback swaps from, instead of
setupRepl receiving a second copy that had to agree.
- all_names + closestCommand move to SlashCommand.zig, the command
registry - prompt_assist consumes it like everyone else and
Terminal's closestCommand re-export disappears.
- picker treats a tty that refuses raw mode as NotInteractive and
degrades to the line prompt instead of leaking termios errnos to
callers that can only blanket-catch.
- kitty keyboard flags become named ansi.zig constants shared by
Terminal.readLine and picker's RawTerminal.
- skipWhitespace was std.mem.indexOfNonePos; single-use style consts
inline into the style table; drop the dead CompletionSource default
and doc-comment splice in Spinner.
Completion, ghost hints, and prompt highlighting (~640 lines) were
cohabiting with Terminal's readline lifecycle and output printing. They
now live in prompt_assist.zig, which owns the isocline callbacks, the
ps-* style palette, and the slash-command name table. The C callbacks
read a small prompt_assist.State (js_mode, completion_source,
history_paths) embedded in Terminal, replacing the three loose fields.
Pure code motion otherwise; the valueAt/renderSchemaHint tests move
with their code and stay in the suite via Terminal's test hook.
The numbered/interactive picker (ChoiceState, RawTerminal, render loop)
was ~215 self-contained lines inside Terminal.zig. It runs before - or
without - the isocline REPL (provider selection during setup), so
settings.zig no longer imports the isocline-configured Terminal at all.
Pure code motion; the ChoiceState tests move with it and stay in the
suite via Agent.zig's test hook.
Terminal.columns() had exactly one caller (Spinner's line renderer) and
Terminal itself never used it. Moving it breaks the Spinner<->Terminal
import cycle and stops Spinner type-checking against the isocline
@cImport for one ioctl.
- Add highlighting for JS functions, methods, types, and template
interpolations.
- Introduce teal color and adjust cyan to bright cyan.
- Import `ansi.zig` directly instead of through `Terminal`.
- Add PandaScript semantics note to the agent's system prompt.
- Refactor markdown table rendering and streaming.
- Extract ANSI escape codes to a dedicated `ansi.zig` module.
- Consolidate styled output rendering in `Terminal.zig`.
- Simplify dollar variable highlighting and table measurement.
Extracts the JavaScript highlighting logic from `Terminal.zig` into a
reusable `js_highlight.zig` module. Uses this module to syntax-highlight
markdown fenced code blocks in `md_term.zig` using ANSI escape codes.
Introduces an incremental markdown renderer (`md_term.Stream`) to
format streamed assistant responses in real time. Buffers lines,
maintains code fence state across chunks, and temporarily withholds
tables to render them with proper column alignment once complete.
- Use a 256-ramp gray for `ansi.dim` to improve readability.
- Track and re-apply active styles in nested markdown spans.
- Collapse extra spaces after list markers.
Style the assistant's answer in the interactive agent REPL with ANSI
escapes: headings, bullet/numbered lists, bold/italic/inline-code/strike,
and links. Rendering is gated to the REPL on a real terminal, so
`--task`/piped output stays verbatim for programmatic consumption.
Adds src/agent/md_term.zig (markdown -> ANSI renderer) and wires it into
Terminal.printAssistant.
Streaming defaulted on for every mode, so one-shot `--task` and script
runs interleaved intermediate assistant commentary into stdout, which
wrappers treat as the answer. Gate the stream hook on `Terminal.isRepl`
so non-interactive modes keep the buffered final answer.
The docs promise triple-quoted values that span multiple lines, but the
REPL dispatched every physical line immediately, so the multi-line
/extract form died with 'unterminated quote' on its first line. A slash
command that leaves a '''...''' block open now keeps reading lines at a
continuation prompt until the block closes; Ctrl-D abandons it.
Allows tools like `/getEnv` with a single optional field to accept
positional arguments. Also adds autocompletion and ghost hints for
live `LP_*` environment variables.
Additionally, fixes a memory leak in `settings.zig` when parsing
invalid ZON configurations.
Updates isocline to support idle callbacks and registers a hook to
pump the session's curl multi while waiting for user input. This
prevents connection timeouts. Also refactors the idle pumping logic
into `Session.idleSlice` to share it with the MCP server.
* Revert "agent: enhance /save progress and verification feedback"
This reverts commit 54f467d1fa.
* Revert "agent: verify synthesized scripts during /save"
This reverts commit b141da30ca.
* agent: extract save helpers to save.zig
Moves pure helper functions related to the `/save` command (parsing,
validation, file writing, prompt shaping) from `Agent.zig` to a
dedicated `save.zig` module.
Introduces a multi-step synthesis process for `/save` that derives a
logical JSON output schema and uses a dry-run runtime to verify
candidate scripts. The LLM can now run and self-correct its scripts
using a new `run_script` tool before finalizing the save.
Statically assert that the banner fits within 80 columns at compile
time. This removes the need to dynamically measure terminal width
and conditionally hide the logo.
Updates the isocline dependency to use its native hints for Ctrl-D
and Esc. Removes the custom status bar rendering logic, and prints
the active model and effort level at REPL startup instead.
Prints a Braille-art Lightpanda logo alongside the welcome text and
command hints if the terminal is wide enough. Otherwise, falls back
to a text-only layout.
Also exposes `Terminal.displayWidth` to assist with layout calculations.
