c3p diff

c3p diff <a> [<b>] compares the resolved (and merged) file lists of two profiles. With one argument, it compares <a> against the currently active profile. The summary line shows byte deltas: (+added -removed ~changed bytes).

This is the right tool for “what would happen if I switched from dev to ci?” — it shows the file-level delta without touching disk.

c3p diff — file-level diff — I do believe these two differ


USAGE
  c3p diff <a> [<b>] [options]


DESCRIPTION
  Compares two profiles' resolved+merged file lists. If <b> is omitted,
  compares <a> to the currently active profile. The summary line shows
  byte deltas: `(+added -removed ~changed bytes)`.


OPTIONS
  --preview          render unified-diff content for changed entries (capped at 20 lines per file)


GLOBAL OPTIONS
  --cwd=<path>     project root (default: cwd)
  --json           machine-readable output (silences human output)
  --quiet, -q      silence human output (preserves errors + exit codes); incompatible with --json


EXAMPLES
  c3p diff dev ci          # compare two profiles
  c3p diff dev             # compare dev to the active profile
  c3p diff dev ci --preview # also show what changed inside each file


EXIT CODES
  0  success
  1  bad argv (missing required <a>)
  2  IO fault (read failure on profiles dir or state file)
  3  cycle / missing include / missing extends parent in either profile

Example

Section titled “Example”
Terminal window
# What changes between dev and ci?
