我最终得到了一个修补源代码的脚本；修补源代码听起来有风险，但在存在版本控制的情况下，风险是可以接受的。
所以我制作了一个版本，提交了源代码，制作了另一个版本，提交了源代码，然后查看了差异，用 Python 编写了一个补丁脚本。
我不确定这是否是最佳解决方案。 （而且代码遗漏了一些 os.path.joins）
脚本的核心是以下函数：
# In the file 'fname',
# find the text matching "before oldtext after" (all occurrences) and
# replace 'oldtext' with 'newtext' (all occurrences).
# If 'mandatory' is true, raise an exception if no replacements were made.
def fileReplace(fname,before,newtext,after,mandatory=True):
with open(fname, 'r+') as f:
read_data = f.read()
pattern = r"("+re.escape(before)+r")\w+("+re.escape(after)+r")"
replacement = r"\1"+newtext+r"\2"
new_data,replacements_made = re.subn(pattern,replacement,read_data,flags=re.MULTILINE)
if replacements_made and really:
f.seek(0)
f.truncate()
f.write(new_data)
if verbose:
print "patching ",fname," (",replacements_made," occurrence", "s" if 1!=replacements_made else "",")"
elif replacements_made:
print fname,":"
print new_data
elif mandatory:
raise Exception("cannot patch the file: "+fname)
您可能会发现以下用途之一：
# Change the application resource package name everywhere in the src/ tree.
# Yes, this changes the java files. We hope that if something goes wrong,
# the version control will save us.
def patchResourcePackageNameInSrc(pname):
for root, dirs, files in os.walk('src'):
if '.svn' in dirs:
dirs.remove('.svn')
for fname in files:
fileReplace(os.path.join(root,fname),"import com.xyz.",pname,".R;",mandatory=False)
还有一个功能可以将资产从x-assets-cfgname复制到assets（之前发现对我来说在assets中有一个子目录更方便）。
def copyAssets(vname,force=False):
assets_source = "x-assets-"+vname+"/xxx"
assets_target = "assets/xxx"
if not os.path.exists(assets_source):
raise Exception("Invalid variant name: "+vname+" (the assets directory "+assets_source+" does not exist)")
if os.path.exists(assets_target+"/.svn"):
raise Exception("The assets directory must not be under version control! "+assets_target+"/.svn exists!")
if os.path.exists(assets_target):
shutil.rmtree(assets_target)
shutil.copytree(assets_source, assets_target, ignore=shutil.ignore_patterns('.svn'))
嗯，你明白了。现在您可以编写自己的脚本了。
