bobframes 0.2.6

RenderDoc capture pipeline: ingest, analyze, render.

BobFrames

RenderDoc capture pipeline: ingest, analyze, render. Point it at a folder of .rdc captures and it produces _data/ (Parquet tables) plus _reports/ -- static, offline, file://-safe HTML you can browse: a one-page build-health summary, a reports dashboard, per-aspect reports (overdraw, shader hotlist, instancing, draws-by-class, pass-GPU, cross-run trend), and a per-drop drill-down data browser. Reports are self-contained, printable, Ctrl-F-able, and work with JavaScript off. Windows-only in v1.

Built for Mayhem Studios -- see Built for Mayhem Studios below.

Requirements

• Windows 10 or later (the replay stage drives qrenderdoc, which is Windows-only in v1).
• Python 3.10 - 3.13.
• RenderDoc 1.x, or Arm Performance Studio, providing renderdoccmd and qrenderdoc on disk.

Install

pipx install bobframes
bobframes check

bobframes check prints the resolved paths for renderdoccmd and qrenderdoc and exits non-zero if either is missing, so you can confirm the toolchain before a long ingest.

Quickstart

cd path\to\captures      # a folder of <Area>\<YYYY-MM-DD[_label]>\*.rdc
bobframes ingest .       # export, parse, replay, parquetize, derive, render
bobframes serve .        # open a local static preview of the reports

ingest writes Parquet under _data/ and HTML under _reports/. Re-run bobframes render . any time to rebuild the HTML from existing Parquet without re-replaying captures.

Commands

Command	Purpose
ingest [root] [--area X] [--label Y] [--capture N] [--force] [--pixel-grid 4] [--render-only]	Full pipeline: export, parse, replay, parquetize, derive, manifest, commit, catalog, render.
render [root] [--area X] [--label Y] [--accent OKLCH] [--accent-data OKLCH] [--watch]	Rebuild HTML and catalog from existing Parquet. --accent/--accent-data re-hue the theme for this render (ADR-45). --watch re-renders on design_tokens.toml, chrome, or .bobframes.toml edits (alpha).
ab [root] --baseline-label X --compare-label Y	All reports for one drop pair under _reports/ab/<pair>/.
report [root] <name>	Build one named report (summary, draws-by-class, trend, instancing, pass-gpu, shader, overdraw, dashboard). summary is the exec build-health one-pager.
catalog [root]	Rebuild _data/_catalog.parquet only.
lint <file>...	Check HTML or markdown against the banlist.
check	Print resolved tool paths; non-zero when a tool is missing.
serve [root] [--port 8000] [--bind 127.0.0.1]	Static preview via the stdlib HTTP server.
package [root] [--inline] [--light] [--redact] [--redact-paths {strip,fail}] [--out PATH] [--run KEY] [--no-summary-file] [--stage]	Bundle a rendered tree into a shareable <project>-<rundate>-report.zip + a standalone <project>-<rundate>-summary.html, both written OUTSIDE <root> (non-mutating). --redact scrubs device/host provenance + absolute paths for external sharing.
preview [root] [--accent OKLCH] [--accent-data OKLCH]	Render the chrome gallery to _reports/_chrome_preview.html; no capture data needed. --accent previews a theme override before you commit it.
export-tokens [--format toml|json|css] [--theme-template]	Print the design tokens to stdout in the chosen format. --theme-template emits a paste-ready [theme] block for .bobframes.toml.
smoke [--data DIR]	End-to-end check; render-only against the bundled fixture when --data is omitted.
version	Print bobframes, schema, and pyarrow versions.

<root> is positional and defaults to .. Flags are long-form only. Exit codes: 0 success, 1 pipeline or build failure, 2 usage error, 3 external tool missing, 4 interrupted.

Sharing a report

bobframes package <root> turns a rendered tree into two friendly artifacts beside it (it only READS <root>):

• <project>-<rundate>-report.zip -- the full explorable tree. Extract the whole folder before opening (index.html, then the Build Health Summary): the pages link each other and a shared _assets/ folder by relative path, so opening one file straight out of the zip breaks those links.
• <project>-<rundate>-summary.html -- a standalone, self-contained one-pager. Email it, double-click it, or Ctrl-P -> Save as PDF; no unzip needed. (Its deep links into the reports only resolve when the zip is shipped alongside.)

The zip DEFAULTS to shared assets: the ~95 KB of chrome (font + CSS + JS) lives once in _assets/ and every page links it, so a multi-run bundle is markedly smaller. Because the pages share that folder, no single page is portable on its own -- keep the extracted folder together, or send the standalone summary.html when you need just one file. --inline opts out and makes each page self-contained (larger, but any single report file is portable). --light bundles only index.html

• the top-level reports (no drill pages or data) for a quick "read, don't drill" share.

Sharing externally -- --redact

bobframes package <root> --redact produces a bundle safe to hand to someone outside your team. It scrubs the GPU / driver / CPU / OS + capture-tool versions from every page's device strip (replaced with redacted), drops the raw provenance sidecars (_manifest.json, frame_metadata.jsonl) from the bundle, and replaces absolute Windows paths (C:\...) with <path redacted> across the pages and the downloadable CSVs. Redaction re-renders the tree, so --inline --redact is no longer a fast copy.

• --redact-paths=strip (default) -- replace the path tokens; the bundle stays usable on a real capture.
• --redact-paths=fail -- a CI completeness check: exit nonzero (don't write the zip) if any absolute path remains in a rendered page, so a leak fails the build.

Caveat: the pages and the downloadable CSVs are sanitized, but the binary .parquet tables still contain resource paths (they can't be string-edited safely) -- strip _data/ if the parquet itself must leave your team. UNC (\\host\share) and forward-slash (C:/...) paths are not auto-stripped.

Customizing reports

The look is shadcn-clean, neutral, and flat by default. Two ways to re-color it:

Pip installs -- re-hue without editing source (recommended)

pip install bobframes puts the design tokens in site-packages, where edits are lost on upgrade -- so re-hue the accent / status / chart colors through the config cascade instead:

• Persistent: add a [theme] section to .bobframes.toml in your capture root (or %APPDATA%/bobframes/config.toml). bobframes export-tokens --theme-template prints a ready-to-paste starter with just the overridable color knobs.
• One-shot: bobframes render . --accent '<oklch>' (and --accent-data '<oklch>') -- the top precedence tier (CLI > env > config > bundled default). bobframes preview --accent '<oklch>' previews it with no capture data.

Only color hues (accent, the four status colors, the draw-class + chart palette) are overridable; layout, spacing, type, and the table engine stay bundled, so an override can never desync the rendering. A bad or non-color value warns and is ignored. --watch live-reloads on .bobframes.toml edits too.

Source checkouts -- edit the bundled tokens

The full palette lives in bobframes/reports/design_tokens.toml (colors, spacing, type, motion, radius, and base layout sizes). The CSS variable name is fixed by its key: surface_0 becomes --surface-0, accent_primary becomes --accent-primary.

bobframes preview                 # writes _reports/_chrome_preview.html (every component, no data)
# edit a value in design_tokens.toml
bobframes preview                 # under a second; reload the page in a browser
bobframes render C:\captures      # apply the change to real reports from existing Parquet

bobframes render --watch re-runs render-only whenever design_tokens.toml, a chrome module, or .bobframes.toml changes (alpha; a 500ms poll, no extra dependency). bobframes export-tokens --format css prints the live :root block; --format json the nested table; --format toml the file itself.

External tools

The export stage runs renderdoccmd convert; the replay stage runs qrenderdoc --python. bobframes resolves both from (in order) a config file (.bobframes.toml), version-globbed Arm Performance Studio install paths, and PATH. Install RenderDoc / Arm Performance Studio anywhere on those, or point a config entry at it. Run bobframes check to see what was resolved.

Output layout

<root>/
  index.html                          root catalog view
  <area>/<drop>/                      raw RDC inputs (left untouched)
  _data/                              pipeline outputs
    _catalog.parquet (+ .csv, .json)
    _global_entities.parquet (+ .csv)
    _query_examples.md
    <area>/<drop>/                    per-drop data (29 Parquet tables)
      *.parquet (+ matching .csv)
      _manifest.json, _resource_labels.json
      shader_src/*.glsl, jsonl sidecars
      done.marker
  _reports/                           rendered HTML
    *.html (dashboard + reports)
    ab/<pair>/*.html
    drill/<area>/<drop>/index.html    per-drop browser
    _cache/

The catalog stores each drop's path relative to <root> for portability.

Migrating from _analysis

v1 is a hard rename of the older project-embedded _analysis package, with no compatibility shim: python -m _analysis.* stops working once bobframes is installed. Map old invocations to new ones:

Old (_analysis)	New (bobframes)
python -m _analysis.run --root . --area X --label Y	bobframes ingest . --area X --label Y
python -m _analysis.reports.ab --root . --baseline-label X --compare-label Y	bobframes ab . --baseline-label X --compare-label Y
python -m _analysis.lint <file>	bobframes lint <file>
python -m _analysis.tests.smoke	bobframes smoke

Troubleshooting

Symptom	Resolution
renderdoccmd not found (exit 3)	Install RenderDoc or Arm Performance Studio, or put the executable on PATH; confirm with bobframes check.
qrenderdoc replay hangs	v1 kills the replay process tree on timeout and records capture_status='replay_failed' for that capture; the rest of the drop still completes. Re-run with --force to retry.
Lint failure during render	The emitted HTML contains a banned token. Run bobframes lint <file> to see the line and label.
schema mismatch (exit 1)	A drop's _manifest.json schema version differs from the installed schema. Rebuild it with bobframes ingest --force (the v1 schema-migration path; see G-3).
Permission denied on _data	Close any viewer holding a Parquet open, then re-run; writes are staged and renamed atomically.

Advanced

• A/B reports: bobframes ab . --baseline-label OLD --compare-label NEW builds a side-by-side set.
• Programmatic use: import bobframes.schemas, bobframes.discovery, and bobframes.paths to drive table lookups, drop discovery, and path resolution from your own scripts.
• bobframes/probes/whatif.py is a manual qrenderdoc-side probe and is not wired as a CLI command.
• TOML config (.bobframes.toml), an externalized draw classifier, and design-token theming ([theme] / --accent) shipped in v0.2.6. bobframes package produces shareable, optionally redacted bundles (see Sharing a report).
