I have created a simple tool(python script) that creates a self
sufficient package ready for deployment. Current implementation is
based on shell scripting to set environment for the app and finally
execute "python main.py".
I am planning to convert "main.py" into an executable. The plan is to
rip the unnecessary code from source code that produce python
executable such as command line arguments etc, use "main.py" as python
string (hardcoded inside executable source) and execute it using
"exec" or similar methods and finally creates executable.
Am I right here? Is this is the correct approach?
From what you write here, I'm not exactly sure what you want to achieve,
but...
For example a simple script:
import os
import math
print math.sin(23.0)
print os.getenv("PATH")
Once I'll convert above script as i have mentioned above in an
executable say: "myapp", executing "myapp" will print messages on
console.
Assuming that Python is installed on the machine and readily runnable from
the PATH, this will make the script executable:
#!/usr/bin/env python
import os
import math
...
Note that the file must have the executable bit set.
Search for "shebang", which is the spelled-out name for the "#!" special
file prefix.
