Package Exports
- node-diff3
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (node-diff3) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
node-diff3
This is a node.js library for text diffing and three-way-merge.
It originally came from project Synchrotron, created by Tony Garnock-Jones. For more detail please visit:
Usage
patch: function (file, patch)
Applies a patch to a file.
Given file1 and file2, diff.patch(file1, diff.diffPatch(file1, file2)) should give file2.
diffIndices: function(file1, file2)
We apply the LCS to give a simple representation of the offsets and lengths of mismatched chunks in the input files. This is used by diff3MergeIndices below.
diff3MergeIndices: function (a, o, b)
Given three files, A, O, and B, where both A and B are independently derived from O, returns a fairly complicated internal representation of merge decisions it's taken. The interested reader may wish to consult
Sanjeev Khanna, Keshav Kunal, and Benjamin C. Pierce. "A Formal Investigation of Diff3." In Arvind and Prasad, editors, Foundations of Software Technology and Theoretical Computer Science (FSTTCS), December 2007.
diff3Merge: function (a, o, b, excludeFalseConflicts)
Applies the output of diff.diff3MergeIndices to actually construct the merged file; the returned result alternates between "ok" and "conflict" blocks.
merge: function (a, o, b)
build a merge file.
mergeDigIn: function (a, o, b)
build a digin style merge file.
