Git Add Methods

Git Add Lines

git add -e

Select lines of changes interactively. This allows you to stage only specific lines of changes in a file.
Pros: More control over what gets staged. Cons: More manual work, you have to edit the patch file yourself, which can be error-prone and time-consuming.

Guidelines:

• staged changes are marked with a "+" at the beginning of the line.
• unstaged changes are marked with a "-" at the beginning of the line.
• unchanged lines are not marked.
• To stage a change, add a "+" at the beginning of the line.
• To unstage a change, add a "-" at the beginning of the line.
• To keep a line unchanged, leave it as is.

Git Add Hunks

git add -p

Select hunks of changes interactively. This allows you to stage only parts of the changes in a file.
Pros: Easier to use than the -e method for staging specific parts of changes.
Cons: Sometimes split won't work, which will force you to use the -e method.

Guidelines

• Run git add -p <file> or git add -p to go through patch hunks interactively.
• For each hunk, choose:
  • y to stage this hunk
  • n to leave it unstaged
  • s to split the hunk into smaller parts
  • e to edit the hunk manually
  • q to quit and leave remaining hunks unstaged
  • a to stage this hunk and all remaining hunks
  • d to leave this hunk and all remaining hunks unstaged
• If you choose s, Git will attempt to split the hunk into smaller hunks so you can stage a smaller section.
• If you choose e, Git opens the patch in a temporary editor; add + to lines to stage, - to lines to keep unstaged, then save and close.
• When finished, run git status to verify which hunks were staged.
