What is the "regex function name" for git log -L: <funcname>: <file>

Question

I have the following Swift function in my file Main/VProj/AppModel.swift

    func createItemAndSegment(image:UIImage, completionHandler:(Item?, NSError?)->Void) {
        \\[...]
    }

Documentation for git log -L :<funcname>:<file>approves

-L <start>, <end>: <file>

-L: <funcname>: <file>

Trace the evolution of the line range specified by "<start>, <end>" (or the name of the regex function <funcname>) in the <file> file.

But the teams

• git log -L :createItemAndSegment:Main/VProj/AppModel.swift
• git log -L :'createItemAndSegment':Main/VProj/AppModel.swift
• git log -L :'/createItemAndSegment/':Main/VProj/AppModel.swift

everything crashes with an error starting at line 1: no match

When the documentation states what :<funcname>the "regular function name name" is, what does it look like?

Answer 2

, , JS git log -L. <start><end>:<file>. , <end> -, .

:

git log -L '/myFunction (params) {/','/^ }/':myClass.js

, :

git log -L '/int main/',/^}/:main.c

, :

$ git log -L '/myFunction (params) {/',/^  }/:myClass.js

fatal: Invalid object name '}/'.

() <end>: /^ }/ = > '/^ }/'.
