ComfyUI Graph-Walk — IIB parser plugin

A drop-in parser plugin for sd-webui-infinite-image-browsing (IIB) that correctly reads generation metadata from ComfyUI images.

Why

IIB's built-in ComfyUI parser only handles simple, linear workflows and fails silently on anything more complex, producing wrong or missing model name, prompts, seed, steps, CFG scale and image size.

This plugin replaces it. It modifies no core IIB files (uninstall by deleting this folder) and never writes to your image files — all metadata is read live from the workflow graph embedded in each image at scan time.

Requirements

• Python ≥ 3.10 (uses PEP 604 X | None type hints)
• A reasonably recent IIB with the plugin loader (plugins/ directory). The plugin imports a few IIB internals, including one private helper for a non-standard EXIF fallback; that helper's absence degrades only that fallback, not the whole plugin. Tested against IIB v1.8.0.

Install

1. Copy this comfyui_graphwalk/ folder into IIB's plugins/ directory.
2. Restart IIB (plugins load only at startup). The console prints IIB loaded plugin: ComfyUI Graph-Walk.

Every newly scanned image is now parsed correctly.

Refresh already-indexed images (one-time)

IIB caches parsed metadata in its SQLite DB (iib.db), so already-indexed images keep their old (wrong) info until the cache is invalidated. Run one of the following.

Recommended — targeted invalidation (preserves the rest of the cache)

Stop IIB, then run (uses IIB's bundled Python; adjust the iib.db path if needed):

python -c "import sqlite3,os; db=os.path.expanduser('~/sd-webui-infinite-image-browsing/iib.db'); c=sqlite3.connect(db); c.execute(\"DELETE FROM image_tag WHERE image_id IN (SELECT id FROM image WHERE exif LIKE '%Source Identifier: ComfyUI%' AND exif_edited=0)\"); n=c.execute(\"DELETE FROM image WHERE exif LIKE '%Source Identifier: ComfyUI%' AND exif_edited=0\").rowcount; c.commit(); print('invalidated:', n)"

Then start IIB and browse the folder, or click "Rebuild image index" once, to re-index the removed rows. Only ComfyUI entries are touched, manually edited entries (exif_edited=1) and their tags are preserved, and the command is safe to re-run.

Simplest — full reset

Stop IIB, delete the DB, restart. Re-scans everything; custom tags are lost.

rm ~/sd-webui-infinite-image-browsing/iib.db

Not recommended

• touch-ing image files forces a re-scan but destroys original mtimes (breaks date sorting).
• "Rebuild image index" alone rebuilds tags but does not refresh the cached exif, so detail-panel info stays stale. Pair it with the invalidation above.

How it works

Each ComfyUI image embeds its full workflow graph. The plugin walks that graph backwards from the sampler node — through LoRA loaders, Reroutes, conditioning merges and other intermediates — until it reaches the source values (checkpoint name, CLIP encoders, latent size, seed/steps/CFG scalars). These are assembled into an A1111-style parameters string and passed to IIB's parse_generation_parameters, so tags, search and "Send to txt2img" keep working.

Prepended to IIB's parser list, it transparently replaces the built-in ComfyUI parser; other image types (A1111, Fooocus, …) are untouched. PNG, WEBP and JPEG are supported.

Coverage is broad but not exhaustive — workflows using node types not listed below may produce incomplete results.

Supported nodes

Sampler entry points

Node	Pack
KSampler	built-in
KSamplerAdvanced	built-in
KSampler (Efficient)	efficiency-nodes
KSamplerAdvanced (Efficient)	efficiency-nodes
Tiled KSampler	ComfyUI-TiledDiffusion
BNK_Unsampler	ComfyUI-BNK

Prompt text — CLIP encoders

Reached by following the positive / negative conditioning edges.

Node	Notes
CLIPTextEncode	standard SD 1.x / 2.x
CLIPTextEncodeSDXL	reads both text_g (global) and text_l (local)
CLIPTextEncodeSDXLRefiner
smZ CLIPTextEncode	smZNodes
BNK_CLIPTextEncodeAdvanced	ComfyUI-BNK

Prompt text — text resolution chain

Followed recursively from a text input until a string is produced.

Node	Behaviour
Reroute	transparent wire redirect
ImpactWildcardProcessor	reads populated_text (expanded wildcards at mode='reproduce')
RegexReplace	follows upstream text, then applies the regex substitution
StringFunction / StringFunction|pysssss	concatenates text_a, text_b, text_c
StringConcatenate	joins string_a and string_b using the delimiter widget (default " ")
Primitive / ShowText / Note / TriggerWord Toggle / …	any node storing a scalar in value, text, string, populated_text, or trigger_words

Conditioning

• Passthrough (continue upstream): Reroute · ConditioningSetTimestepRange · ConditioningSetArea · ConditioningSetAreaPercentage · ConditioningSetMask · unCLIPConditioning
• Merge (both inputs joined): ConditioningCombine · ConditioningConcat · ConditioningAverage
• Slot-aware passthrough (output slot 0 → positive input, slot 1 → negative input): ControlNetApplyAdvanced · ControlNetApply

Model

• Checkpoint loaders (terminus, returns ckpt_name / unet_name): CheckpointLoaderSimple · CheckpointLoader · unCLIPCheckpointLoader · Checkpoint Loader
• Passthrough (continue upstream): LoraLoader · LoraLoaderModelOnly · Lora Loader (LoraManager) · Power Lora Loader (rgthree) · Lora Loader Stack (rgthree) · ModelMergeSimple · ModelMergeAdd · ModelMergeBlocks · CLIPSetLastLayer · ModelSamplingDiscrete · ModelSamplingContinuousEDM · Mahiro · CFGZeroStar · Epsilon Scaling · IPAdapterFaceID · IPAdapterAdvanced · IPAdapterStyleComposition · AttentionCouplePPM · FreeU · FreeU_V2 · PerturbedAttentionGuidance · SelfAttentionGuidance · RescaleCFG · DifferentialDiffusion · Reroute

Image size — latent nodes

Width/height read from EmptyLatentImage · EmptySD3LatentImage · EmptyHunyuanLatentVideo (direct or Primitive-referenced scalars).

Reroute and any switch node whose class name contains Switch (e.g. ImpactSwitch, ImpactInversedSwitch) are followed automatically, using the select input to pick the active branch.

Adding a node

Most gaps are fixed by adding a class name to the right set near the top of main.py — no new logic needed if the node merely passes a signal through:

• pure model passthrough (e.g. another LoRA loader) → MODEL_PASSTHROUGH
• conditioning passthrough / merge → COND_PASSTHROUGH / COND_COMBINE
• another CLIP text encoder → TEXT_ENCODE_CLASSES
• a sampler variant → SAMPLER_CLASSES
• an empty-latent variant → LATENT_SIZE_CLASSES

Nodes that transform text (concatenate, regex, wildcards, …) need a dedicated branch in resolve_text. PRs welcome.
