A couple of months ago, I posted about my experience with making a Python dependency graph.
Of course, as the post states, I was originally looking for a way to make a graph showing the relationship among PHP files in regard to "include" statements.
Well, I'm home sick and after a few hours of trying to find an easy, out-of-box solution I gave up and rolled my own Python script to make me a DOT graph file.
I didn't have anything better to do.
The results are pretty simplistic, but I'm happy enough with it for now.
The Python script takes three arguments: the directory in which the PHP files exist, whether to search recursively or not (0=no, 1=yes), and the name of the output file as such:
$ python makeDOT.py blog/wordpress 1 wordpressIncludes.dot
#####
#importing modules
import glob, re, sys, os, fnmatch
br = "\n"
tab = "\t"
#####
#exiting if all 3 arguments are not passed via command line
def fail():
print ("ERROR: " + str(len(sys.argv)-1) + " of 3 required arguments provided.")
sys.exit()
#####
#getting arguments passed via command line
#testing for root DIRECTORY string
try: myDir = sys.argv[1]
except: fail()
#testing for RECURSION boolean
try: myRec = sys.argv[2]
except: fail()
#testing for OUTPUT filename string
try: myFile = sys.argv[3]
except: fail()
#####
#making list of PHP files within DIRECTORY
if myRec == "0": #without recursion
myDir2 = myDir + "/*.php"
PHP_list = glob.glob(myDir2)
elif myRec == "1": #with recursion
PHP_list = []
for dirname, dirnames, filenames in os.walk(myDir):
for filename in filenames:
if fnmatch.fnmatch (filename,("*.php")):
match = os.path.join(dirname,filename)
PHP_list.append(match)
#make an empty list;
#tuples will go in the list;
#each tuple will contain a PHP filename and a PHP filename it includes
includeList = []
#iterate through each PHP file and place tuples in the list
for phpFile in PHP_list:
fileOpen = open(phpFile, "r")
#for each line in a PHP file
for line in fileOpen:
m = re.match(r"(.*)include(.*\()(.*)\)", line) #for include(),include_once()
if m:
matchFile = m.group(3)[1:-1]
if matchFile[-4::] == ".php": #only PHP files
phpFile = phpFile.replace("\\","/")
matchFile = matchFile.replace("\\","/")
matchFile = matchFile.replace("\"","")
matchFile = matchFile.replace('\'',"")
includeList.append([phpFile[len(myDir)+1:], matchFile])
else: pass
m = re.match(r'(.*)require(.*\()(.*)\)', line) #for require(), require_once()
if m:
matchFile = m.group(3)[1:-1]
if matchFile[-4::] == '.php': #only PHP files
phpFile = phpFile.replace("\\","/")
matchFile = matchFile.replace("\\","/")
matchFile = matchFile.replace("\"","")
matchFile = matchFile.replace('\'',"")
includeList.append([phpFile[len(myDir)+1:], matchFile])
else: pass
#####
#creating DOT file
dot = open(myFile, "w")
#writing to DOT file
dot.write("digraph {" + br)
for a,b in includeList:
dot.write(tab)
dot.write("\"")
dot.write(a)
dot.write("\"")
dot.write(" -> ")
dot.write("\"")
dot.write(b)
dot.write("\"")
dot.write(";")
dot.write(br)
dot.write("}")
dot.close()
#####
#exiting
sys.exit()
I ran the Python script on the PHP scripts for MXMLiszt.
Then I used the "circo" layout engine in Graphviz – specifically the Gvedit.exe application – on this resultant DOT file.
Here's the result:
