打印移植源变更集哈希

Question

We've transplanted a changeset from another repository to the current one. It seems to us that the transplant extensions stores the original changset hash in an extra field which can be shown with hg log --debug , like:

changeset:   720:092506
tag:         tip
parent:      ...
parent:      ...
manifest:    ...
user:        ...
date:        ...
files:       ...
extra:       branch=default
extra:       transplant_source=\xe3>\xa7py\xff\xcda\x93d\xde\xa5\xb5\xa6\xf7\xed\xc0\x16\x82\xa3

Here the original changset hash ( transplant_source ) is not too readable and usable. How can we print the transplant_source in a readable format with hg log command?

I've played with ifeq and the list operator without success.

令人作呕，并且没有回答问题，但似乎可以正常工作（Python 2）：:)

hg log --debug | python -c "import sys, re; x=re.compile(r'^extra:\\\\s+transplant_source='); print '\\\\n'.join([l.split('=',1)[0]+'='+eval('\\"'+l.split('=',1)[1].strip()+'\\"').encode('hex') if x.match(l) else l.rstrip('\\\\n') for l in sys.stdin])"
