Member Function Documentation

findSimilar()

bool SlGit::Diff::findSimilar ( const git_diff_find_options *  options = nullptr ) const

inlinenoexcept

Parameters

options

Options to use (like rename threshold)

Returns

True on success.

git diff -M 

forEach()

int SlGit::Diff::forEach

(

const ForEachCB &

forEachCB

)

const

Invoke forEachCB callbacks for each file, hunk, ... in the diff.

Parameters
