Changes the Visual Studio Window Title by evaluating a user defined expression. Extremely helpful when working with multiple branches of the same project.
Script I use to see current branch in TFS (path) or GIT (git branch) in title:
if( sln_open ) { if (exec git_branch 2 "git rev-parse --abbrev-ref HEAD" sln_dir) { //GIT sln_filename + (exec git_branch 2 "git rev-parse --abbrev-ref HEAD" sln_dir ? " - git["+git_branch+"]" + " - Visual Studio 2015") } else { //TFS or Standard project sln_filename + " - (" + sln_dir +")" + " - " + "Visual Studio 2015" } } else { //No solution open "Visual Studio 2015" }
