3 # Interactive script for sending a collection of Mercurial changesets |
|
4 # as a series of patch emails. |
|
5 # |
|
6 # The series is started off with a "[PATCH 0 of N]" introduction, |
|
7 # which describes the series as a whole. |
|
8 # |
|
9 # Each patch email has a Subject line of "[PATCH M of N] ...", using |
|
10 # the first line of the changeset description as the subject text. |
|
11 # The message contains two or three body parts: |
|
12 # |
|
13 # The remainder of the changeset description. |
|
14 # |
|
15 # [Optional] If the diffstat program is installed, the result of |
|
16 # running diffstat on the patch. |
|
17 # |
|
18 # The patch itself, as generated by "hg export". |
|
19 # |
|
20 # Each message refers to all of its predecessors using the In-Reply-To |
|
21 # and References headers, so they will show up as a sequence in |
|
22 # threaded mail and news readers, and in mail archives. |
|
23 # |
|
24 # For each changeset, you will be prompted with a diffstat summary and |
|
25 # the changeset summary, so you can be sure you are sending the right |
|
26 # changes. |
|
27 # |
|
28 # It is best to run this script with the "-n" (test only) flag before |
|
29 # firing it up "for real", in which case it will use your pager to |
|
30 # display each of the messages that it would send. |
|
31 # |
|
32 # To configure a default mail host, add a section like this to your |
|
33 # hgrc file: |
|
34 # |
|
35 # [smtp] |
|
36 # host = my_mail_host |
|
37 # port = 1025 |
|
38 # tls = yes # or omit if not needed |
|
39 # username = user # if SMTP authentication required |
|
40 # password = password # if SMTP authentication required - PLAINTEXT |
|
41 # |
|
42 # To configure other defaults, add a section like this to your hgrc |
|
43 # file: |
|
44 # |
|
45 # [patchbomb] |
|
46 # from = My Name <my@email> |
|
47 # to = recipient1, recipient2, ... |
|
48 # cc = cc1, cc2, ... |
