"""Configuration that affects the behaviour of Bazaar.
21
Currently this configuration resides in ~/.bazaar/bazaar.conf
22
and ~/.bazaar/locations.conf, which is written to by bzr.
24
In bazaar.conf the following options may be set:
26
editor=name-of-program
27
email=Your Name <your@email.address>
28
check_signatures=require|ignore|check-available(default)
29
create_signatures=always|never|when-required(default)
30
gpg_signing_command=name-of-program
31
log_format=name-of-format
32
validate_signatures_in_log=true|false(default)
33
acceptable_keys=pattern1,pattern2
34
gpg_signing_key=amy@example.com
36
in locations.conf, you specify the url of a branch and options for it.
37
Wildcards may be used - * and ? as normal in shell completion. Options
38
set in both bazaar.conf and locations.conf are overridden by the locations.conf
40
[/home/robertc/source]
41
recurse=False|True(default)
43
check_signatures= as above
44
create_signatures= as above.
45
validate_signatures_in_log=as above
46
acceptable_keys=as above
48
explanation of options
49
----------------------
50
editor - this option sets the pop up editor to use during commits.
51
email - this option sets the user id bzr will use when committing.
52
check_signatures - this option will control whether bzr will require good gpg
53
signatures, ignore them, or check them if they are
54
present. Currently it is unused except that check_signatures
55
turns on create_signatures.
56
create_signatures - this option controls whether bzr will always create
57
gpg signatures or not on commits. There is an unused
58
option which in future is expected to work if
59
branch settings require signatures.
60
log_format - this option sets the default log format. Possible values are
61
long, short, line, or a plugin can register new formats.
62
validate_signatures_in_log - show GPG signature validity in log output
63
acceptable_keys - comma separated list of key patterns acceptable for
64
verify-signatures command
66
In bazaar.conf you can also define aliases in the ALIASES sections, example
69
lastlog=log --line -r-10..-1
70
ll=log --line -r-10..-1
