问题 I'm using Sublime Text 2 to code my programs, and want to run the console within it to compile and run them. Is there any way to embed the console command line inside Sublime Text 2?

This is a simple build script for the C programming language: { "cmd" : ["gcc", "$file", "-o", "$file_base_name"], "cmd" : ["$file_base_name"], "selector"
