How to pass parameters to a build in Sublime Text 3?

You can create a new build system for sublime text and run your script with fixed arguments.

Create a new File in your Packages/User directory (CTRL-SHIFT-P --> "Browse Packages")

New File: Packages/User/my_build.sublime-build

with the following content:

{
   "cmd": ["python", "$file", "arg1", "arg2"]
}

(replace arg1,arg2 by your arguments - you can delete them or add more if you want)

Now restart sublime text and select your build system in the Menu: Tools --> Build System --> my_build. From now on, when you press CTRL-B your build system will be executed.

Don't forget to change it back to "Automatic" if you are working on other files or projects.

There are many options you can set in build files. Please refer to https://docs.sublimetext.io/guide/usage/build-systems.html

I find it easier to use a try catch with default arguments, Sublime's build system becomes annoying to manage. While you do fast paced dev you can just modify the arguments in the except statement.

import sys
try:
    if sys.argv[1]:
        Name = str(sys.argv[1])

except:
    print "no argument given - using DERP"
    Name = "DERP"
