svn commit: r1836350 - /subversion/trunk/tools/dist/release.py

[ju...@apache.org]

Author: julianfoad
Date: Fri Jul 20 14:36:35 2018
New Revision: 1836350

URL: http://svn.apache.org/viewvc?rev=1836350&view=rev
Log:
Teach 'release.py write-news' to insert the output into a file.

With the new option '--edit-html-file=FILE', it inserts the news item
before the first existing news item in FILE instead of printing it.

(It does not take care of remove old news items from 'index.html'.)

* /home/julianfoad/src/subversion-g/tools/dist/release.py
  (write_news): Insert the news before a '<div class="h3" id="news-' line.
  (main): Accept '--edit-html-file=' option.
