Hi all,

Comments from everyone who has worked on or commented on Python 3 are appreciated, especially from Reef, @jcsteh, and @LeonarddeR.

Thanks,

user_docs/en/changes.t2t

josephsl · 2019-07-17T03:59:33Z

Hi, right, thanks for catching this, which also had a grammar problem (will resolve it once I wake up from sleep in the morning). Thanks.

LeonarddeR

You can change the threshold release heading to 2019.3

josephsl · 2019-07-17T05:38:49Z

Hi, I knew there was an issue about mentioning minor versions in docs – thanks for the link to the issue. Thanks.

josephsl · 2019-07-17T14:23:04Z

Hi,

Should we mention textUtils?

Thanks.

LeonarddeR · 2019-07-17T14:59:42Z

yes, sounds like a good idea. Probably best to point at examples from the changelog.

josephsl · 2019-07-17T22:24:50Z

Hi,

Regarding text utils, I have nothing to say - can't come up with a descriptive changelog for developers at the moment.

Anything else from our PR pool? If not, I'll switch the PR to review mode.

Thanks.

LeonarddeR · 2019-07-18T04:58:28Z

How about something within the lines of:

Added a new textUtils module that makes it easier to deal with string differences between Python 3 strings and Windows unicode strings. See the module documentation and textInfos.offsets module for example implementations. (textUtils module to deal with offset differences between Python 3 strings and Windows wide character strings with surrogate characters #9545)

josephsl · 2019-07-18T12:21:57Z

Hi,

Text utils: done.

Thanks.

This is looking pretty good. Please update the description to cover which PR's (to threshold / threshold staging) have been covered by this. You can get most of the way there by copying entries from git log on the threshold branch. I suggest using the checkbox markdown:

- [ ] some PR not covered
- [x] some PR covered

josephsl · 2019-07-22T16:28:36Z

Hi,

I'll use git shortlog to edit the description.

Thanks.

josephsl · 2019-07-23T02:21:17Z

Hi,

To @LeonarddeR: whenever you are ready, please take a look at this PR. Thanks.

feerrenrut · 2019-07-23T12:25:20Z

Thanks @josephsl, I have updated the description so that they render as a checkboxes. It looks like there are still many PR's that need consideration.

josephsl · 2019-07-23T13:45:39Z

Hi, yes, including the just merged one (#9960). Thanks.

feerrenrut · 2019-07-24T10:56:05Z

If no one volunteers before tomorrow (25-July 0600 UTC+0) , then I'll finish this off.

LeonarddeR

I found two sentences where has should be have IMO. Could be wrong for the latter, though.

josephsl · 2019-07-24T20:18:28Z

Hi, I think part of that may have to do with subtle English grammar differences.

josephsl · 2019-07-24T21:06:08Z

Hi,

Let me at least commit the requested edits, and then I think we should decide our next steps.

Thanks.

feerrenrut · 2019-07-25T14:04:29Z

I'd like to get this finished off and merged in, are you going to continue with it @josephsl? I don't think I will hold back threshold any longer.

josephsl · 2019-07-25T14:06:26Z

Hi, feel free to merge – let’s get the party started. Thanks.

josephsl · 2019-07-25T18:31:10Z

Hi,

Clarification: I'm done with this one.

Thanks.

feerrenrut · 2019-08-05T12:10:11Z

@derekriemer The checklist for PR's needs to be completed, I suspect many of these do not need an entry. This is on my list of things to do, but hasn't yet received priority.
