SMake
Simple Make replacement for lazy developers that like Python.
What is it for?
You think that Makefiles are confusing or unreadable? You're too lazy to go through CMake or Autotools? If so, SMake is for you. It's simply a Python module that used in .py file links and compiles your C/C++ project.
Requirements
- Python 3.6+
- Click (optional)
Supported compilers
- gcc
- g++
- clang
Example code
Example for Hello world example:
src/hello.c
:
#include <stdio.h>
int main() {
printf("Hello, SMakefile!\n");
return 0;
}
Smakefile.py
:
import smake_buildtools
import click
sm = smake_buildtools.Smake()
sm.name = 'hello'
sm.obj_dir = 'obj'
sm.bin_dir = 'build'
@click.group()
def cli():
pass
@cli.command()
def install():
sm.gcc.sources = ['src/hello.c']
sm.gcc.compiler_flags.append('pedantic')
sm.gcc.warning_flags.append('all')
sm.gcc.link()
sm.gcc.compile()
@cli.command()
def clean():
sm.remove_dir(sm.obj_dir)
sm.remove_dir(sm.bin_dir)
if __name__ == "__main__":
cli()
Running the script
$ python ./SMakefile.py install
How to install
Using pip:
$ pip install smake_buildtools
Okay, how to use it?
First you need to import SMake:
import smake_buildtools
Defining project
Then define your SMake project:
sm = smake_buildtools.Smake()
sm.name = 'app'
sm.obj_dir = 'obj'
sm.bin_dir = 'build'
Adding source files
You need to add some source files for compiler.
For example, we have sources in src/
and src/module
directories.
For this we can use two SMake methods: Smake.wildcard
and Smake.merge
.
sm.gcc_cpp.sources = sm.merge(
sm.wildcard('src/*.cpp'),
sm.wildcard('src/module/*.cpp')
)
Compiler flags
Then add some flags (here we can use some SFML libs):
sm.gcc_cpp.compiler_flags = ['pedantic', 'static']
sm.gcc_cpp.warning_flags = ['all']
# SFML 2
sm.gcc_cpp.linker_flags.append('sfml-graphics')
sm.gcc_cpp.linker_flags.append('sfml-window')
sm.gcc_cpp.linker_flags.append('sfml-system')
sm.gcc_cpp.linker_flags.append('sfml-audio')
Platform checking
For Linux it's easy to install libraries via the package manager.
But what if you want specifically for Windows to add SFML include/
and lib/
directories?
With help comes Smake.get_platform()
:
# SFML 2
if sm.get_platform().startswith('win'): # win32, win64
sm.gcc_cpp.include_dirs.append('C:\\SFML2\\include')
sm.gcc_cpp.library_dirs.append('C:\\SFML2\\lib')
Compiling and linking
Now the easiest ones are left: compiling and linking.
For this you use Smake.compile()
and Smake.link()
method, respectively.
sm.gcc_cpp.compile()
sm.gcc_cpp.link()
Summary
As you can see, for normal user every line is very clear. If someone wants to compile your code it's easy for them to see what values are used for what.
Example code:
import smake_buildtools
import click
sm = smake_buildtools.Smake()
sm.name = 'app'
sm.obj_dir = 'obj'
sm.bin_dir = 'build'
@click.group()
def cli():
pass
@cli.command()
def install():
sm.gcc_cpp.sources = sm.merge(
sm.wildcard('src/*.cpp'),
sm.wildcard('src/module/*.cpp'))
sm.gcc_cpp.compiler_flags = ['pedantic', 'static']
sm.gcc_cpp.warning_flags = ['all']
# SFML 2
sm.gcc_cpp.linker_flags.append('sfml-graphics')
sm.gcc_cpp.linker_flags.append('sfml-window')
sm.gcc_cpp.linker_flags.append('sfml-system')
sm.gcc_cpp.linker_flags.append('sfml-audio')
if sm.get_platform().startswith('win'): # win32, win64
sm.gcc_cpp.include_dirs.append('C:\\SFML2\\include')
sm.gcc_cpp.library_dirs.append('C:\\SFML2\\lib')
sm.gcc_cpp.compile()
sm.gcc_cpp.link()
# post-linking stuff
if sm.get_platform().startswith('linux') or sm.get_platform() == 'darwin':
target_path = sm.make_path('usr', 'bin', sm.name)
sm.copy_executable_to(target_path)
@cli.command()
def clean():
sm.remove_dir(sm.obj_dir)
sm.remove_dir(sm.bin_dir)
if __name__ == '__main__':
cli()
Save this as SMakefile.py in project root directory and run:
$ python ./SMakefile.py install
