Python implementation generates a simple Makefile file code example _python

In Linux to write a few test procedures, but also a line of input g++ command to compile, when often changed the test code, that time and again the knock (or time and again on the line arrow election) also feel bad, not as fast as make. With the benefits of makefile, I have written a script that automatically searches the ". C" file in the current directory (excluding subdirectories) to generate makefile files.

The code here, limited in functionality (for a single file is a stand-alone test code case), requires a friend to modify to meet the requirements.

Copy Code code as follows:

#! /usr/bin/python
'''
File:genMakefile.py
Author:mike
E-mail:mike_zhang@live.com
'''
Import OS

def genmakefilestr (Dir,surfix = '. C '):
msg = '
msg = msg + ' CC = gcc ' + ' \ n '
msg = msg + ' Cflags =-g-o2-wall ' + ' \ n '

Flist = []
For Dirpath,dirnames,filenames in Os.walk (dir):
For file in FileNames:
name,extension = os.path.splitext (file)
if extension = = Surfix:
Flist.append (name)
# Search the current directory
str1 = ' all:\n '
str2 = ' '
STR3 = ' clean:\n '
For F in Flist:
str1 = str1 + ' \tmake ' + f + ' \ n '
str2 = ('%s%s:%s.o\n ')% (str2,f,f)
str2 = ('%s\t$ (CC)-O%s%s.o\n\n ')% (str2,f,f)
STR3 = ('%s\trm-f%s\n ')% (str3,f)
STR3 = Str3 + ' \trm-f *.o\n '
Strclean = '. c.o:\n\t$ (CC) $ (cflags)-c-o $*.o $<\n '
msg = ('%s%s\n%s\n%s\n%s ')% (Msg,str1,str2,str3,strclean)
#print ' msg: \ n '
#print msg
Return msg

if __name__ = = ' __main__ ':
str = GENMAKEFILESTR ('. ', '. C ')
File = Open ("Makefile", "W")
File.write (str)
File.close ()
Print str

The results of the operation are as follows (example):

Copy Code code as follows:

#./genmakefile.py
CC = gcc
Cflags =-g-o2-wall

All
Make Pfun1
Make Pfun2

pfun1:pfun1.o
$ (CC)-O pfun1 pfun1.o

pfun2:pfun2.o
$ (CC)-O pfun2 pfun2.o

Clean
Rm-f pfun1
Rm-f pfun2
Rm-f *.O

. C.O:
$ (CC) $ (cflags)-c-o $*.o $<

After you run the script, make it.

Report:

Feel the script above is inconvenient, then modify the code as follows:

Print arg

Rename the file genmakefile.py to Genmakefile, copy it to/usr/local/bin, and then execute the following command in the desired directory:

Genmakefile.
