Package: doxygen
Version: 1.8.9.1-3
Followup-For: Bug #785624
Tags: patch
User: reproducible-builds@lists.alioth.debian.org
Usertags: timestamps
Hi.
I created a patch for doxygen that allow get the current date and time
from the DOXYGEN_CURRENTDATETIME environment variable in iso 8601
extended format.
The expected usage in the debian/rules file is the following:
LAST_CHANGE = $(shell dpkg-parsechangelog -S Date)
DOXYGEN_CURRENTDATETIME = $(shell LC_ALL=C date -uIs -d "$(LAST_CHANGE)")
export DOXYGEN_CURRENTDATETIME
Comments are welcome.
Greetings,
Juan Picca
Note: the code for parse the date is simplified from QDateTime
Description: Allow set doxygen current date time from environment variable
Allow use the DOXYGEN_CURRENTDATETIME environment variable for modify the
current date and time used by doxygen for timestamp values.
The expected format for DOXYGEN_CURRENTDATETIME is the ISO 8601 extended
format.
The code for parse the text in iso 8601 format is a simplification of the
code from QDateTime::fromString, QDate::fromString and QTime::fromString.
