fix(antigravity): LS process name for v2.0.6+ + segmented progress bars by sakn0m · Pull Request #509 · robinebers/openusage

sakn0m · 2026-05-25T11:45:58Z

This PR builds on #508 by @kvanzuijlen — credits to them for the initial Antigravity IDE v2 support (v1/v2 DB path detection + IDE marker discovery).

What

Two additional improvements for the Antigravity plugin:

1. Fix LS process discovery

Antigravity v2.0.6 renamed the language server binary from language_server_macos to language_server. Discovery was failing because the plugin looked for the old name. Using language_server is backwards-compatible (substring match covers both names).

2. Segmented progress bar

Antigravity reports quota in 5 discrete steps (0%/20%/40%/60%/80%/100%). Added 4 divider lines to the progress bar so the visual matches the granularity of the data.

Adds segments field to MetricLine::Progress (Rust + TypeScript + host API)
Renders divider lines in the Progress UI component when segments is set
Antigravity plugin sets segments: 5

Testing

Plugin tests: 59/59 pass
Manual test with Antigravity v2.0.6 — LS discovery works, usage data displays correctly
Segmented bar renders properly in the UI

….0.6+ Antigravity v2.0.6 renamed the LS binary from 'language_server_macos' to 'language_server'. The existing discovery failed because the process name didn't match. Using 'language_server' as the process name is backwards-compatible since both binary names contain this substring.

- Fix LS discovery: use 'language_server' instead of 'language_server_macos' to support Antigravity v2.0.6+ which renamed the binary - Add 5-segment dividers to Antigravity progress bars to match the 5-step quota granularity (0/20/40/60/80/100%) - Add 'segments' field to MetricLine::Progress, host API, plugin types, and Progress UI component

Copilot was unable to run its full agentic suite in this review.

Adds support for segmented progress bars in metric lines and improves the Antigravity plugin’s ability to locate OAuth tokens across v1/v2 database locations.

Changes:

Extend metric line schema (TS + Rust) with optional segments for progress metrics.
Render visual segment dividers in the Progress UI component.
Update Antigravity plugin to probe v2 DB path first with fallback behavior, and add tests around path selection/fallback.

thank you. this seems like a bigger (core) change.

could you attach some screenshot/s? cheers!

The main reason for the progress bar changes: Antigravity reports quota in discrete 20% steps (remainingFraction jumps from 1.0 → 0.8 → 0.6 → 0.4 → 0.2 → 0.0). The bar was continuous before. The 4 dividers make this visible.
The other change is just renaming the process to retrieve usage data since Antigravity v2.0.6 renamed the language server binary from language_server_macos to language_server, so discovery was broken.

This is the only attachment since only Antigravity's section was changed.
Note: I haven't yet managed to make the plugin work with Antigravity CLI, only with Antigravity 2.0 GUI.

- Add agy CLI LS discovery via log file (~/.gemini/antigravity-cli/log/) agy uses random ports announced in cli-*.log; discoverAgyPorts parses the latest log, probeAgyLs uses those ports (no CSRF required) - Add listDir host API (Rust + test mock) for log directory listing - Fix loadOAuthTokens: return null on empty/missing token instead of falling through to stale V1 creds (fail LOUD, no silent fallbacks) - Clamp segments to [2, 20] in runtime.rs (prevents excessive DOM nodes) - Remove (line as any).segments cast in provider-card.tsx (TS narrows via discriminated union) - Add CLI-specific tests (port discovery, token refresh via CLI creds)
