I want to use the Mercurial Python API on only changesets that fall within a certain range, and from reading the docs, I haven't been able to work out how to do it.
My code looks like this:
from mercurial import ui, hg
import datetime
repo = hg.repository(ui.ui(), 'path_to_repo' )
start_date = datetime.datetime( 1997, 01, 01 )
end_date = datetime.datetime( 2000, 12, 31 )
# Print every changesetid in required range
for changesetid in repo:
#print repo[changesetid]
changeset = repo.changectx( changesetid )
date = changeset.date()[0]
if ( date > start_date and date < end_date):
# Do stuff...
pass
And the output I get is:
Traceback (most recent call last):
File "test.py", line 14, in <module>
if ( date > start_date and date < end_date):
TypeError: can't compare datetime.datetime to float
Example output dates are:
I've also seen 'hg help dates', but can't tell from this how to convert from a day/month/year date to Mercurial's internal representation.
How do I convert my cutoff dates to a numeric format that is suitable for comparison the date value returned by changectx.date(), please?
PS I know that for an example this trivial, there are better ways of doing this using the hg command directly... what I haven't included in my example code is the complex steps I wish to add at the "Do stuff" point!
Firstly, please remember that the internal Mercurial API is not stable. You should seriously consider using Mercurial's command-line directly if at all possible. Remember that there are XML templates (by passing --style=xml) if you find parsing the default output too annoying.
That said, this is most easily done with revsets, just as you would do at the command line:
from mercurial import ui, hg
repo = hg.repository(ui.ui(), '/some/path/to/repo')
changesets = repo.revs("date('>1999-01-01') and date('<2000-12-31')")
As a bonus, this will go through Mercurial's internal revset optimizer.
