📝 Walkthrough

Walkthrough

Documents a new comfy install --fast-deps option that uses uv for dependency compilation and automatic GPU-specific PyTorch wheel selection; clarifies --uv-compile as using ComfyUI-Manager’s unified resolver with cross-node conflict detection and node attribution. Fast deps, no frets—install in sets.

Changes

Cohort / File(s)	Summary
Documentation Updates README.md	Added --fast-deps docs describing uv-based compilation of core + custom-node requirements into a single lockfile, automatic GPU wheel selection, and a comparison table plus guidance distinguishing --fast-deps vs --uv-compile (unified resolver, cross-node conflict detection, node attribution).
Help Text comfy_cli/cmdline.py	Updated comfy install --fast-deps help text to state it uses uv (Comfy CLI’s built-in resolver) rather than pip; no control-flow or public API changes.

Inline comments:
In `@README.md`:
- Around line 218-220: Two lines in the README containing the sentence starting
with "`pip install`, `--uv-compile` delegates to ComfyUI-Manager's unified
resolver..." have trailing spaces at their ends; remove the trailing whitespace
from those lines (the line with "all custom node dependencies via `uv pip
compile` with **cross-node conflict detection** —" and the following line "it
can identify which node packs have incompatible dependencies and why.") so the
markdown has no trailing spaces, then re-save the file and optionally run a
markdown/whitespace linter to confirm no trailing spaces remain.
- Around line 69-71: Trailing spaces exist in the README paragraph describing
`comfy install --fast-deps`; open the README, locate the paragraph containing
the text "comfy install --fast-deps" and remove the trailing whitespace at the
ends of the affected lines so they are trimmed (ensure no extra spaces remain
after "resolution" and "installation."), then save the file to eliminate the
markdownlint warning.
