Lines of Code modified in each Commit in TFS rest

Question

In TFS api only allow to get the modified file count only.But needed to get each file modified line count (added/deleted) for each commit in rest call.

Answer 1

There isn’t official released REST API to do that. But you can refer to these steps to achieve your requirements

1. Get a list of commits to get a commit’s commit id.
2. Get a commit by commit id (steps 1) to get parents value and repository id (The value at the end of _links>Repository>href) (Using the URL of _links>Changes>href can get file path if you don’t know)
3. Get file diff by this POST request https://[account].visualstudio.com/[team project name] /_api/_versioncontrol/fileDiff?__v=5&diffParameters=[data 1]&repositoryId=[repository id]

The [data 1] value is the JSON data (remove whitespace).

JSON likes:

{
"originalPath":"/index.html",
"originalVersion":"GC[a parent value, step 2]",
"modifiedPath":"/index.html(path: step 2)",
"modifiedVersion":"GC[commit id]",
"partialDiff":true,
"includeCharDiffs":true
}

The result contains this (you need to calculate the items that changeType isn’t equal 0, 2 means remove, 1 means add):

 {
      "changeType": 2,
      "mLine": 9,
      "mLines": [],
      "mLinesCount": 0,
      "oLine": 9,
      "oLines": [
        "    <!-- Polyfill(s) for older browsers -->"
      ],
      "oLinesCount": 1
    },
 {
      "changeType": 1,
      "mLine": 22,
      "mLines": [
        "      <div>2</div>"
      ],
      "mLinesCount": 1,
      "oLine": 23,
      "oLines": [],
      "oLinesCount": 0
    }

You can capture the request URL of a commit (History > Commits > Select a commit) by using Developer Tools Network capture.
