Apply a unified diff patch

Usage

Arguments

ArgumentDescription
patch-filePatch file to apply

Description

The apply command reads a unified diff patch file and applies the changes to the working directory. It supports creating new files, modifying existing files, and deleting files based on the patch content.

After applying, modified artifacts are automatically validated.

Examples

Apply a patch:

paradoc apply changes.patch

Check if patch applies cleanly:

paradoc apply changes.patch --check

Preview changes:

paradoc apply changes.patch --dry-run

Reverse a patch:

paradoc apply changes.patch --reverse

Project and patch rules

apply must run inside a Paradoc project. Patch paths are relative to the project root, even when invoked from a subdirectory. Application is all-or-nothing: conflicts write nothing, and a write failure rolls back prior writes. Failed validation after applying is reported as a warning. Create compatible patches with git diff or diff -u; paradoc diff is a display format and is not an input to apply.
