SYNOPSIS
--------
b4 {mbox,am,attest,pr,ty,diff} [options]
DESCRIPTION
-----------
This is a helper utility to work with patches and pull requests made
available via a public-inbox archive like lore.kernel.org. It is
written to make it easier to participate in a patch-based workflows,
like those used in the Linux kernel development.
The name "b4" was chosen for ease of typing and because B-4 was the
precursor to Lore and Data in the Star Trek universe.
SUBCOMMANDS

* *b4 am*: Create an mbox file that is ready to git-am
* *b4 attest*: (EXPERIMENTAL) Submit cryptographic attestation for patches
* *b4 pr*: (EXPERIMENTAL) Work with pull requests
* *b4 ty*: (EXPERIMENTAL) Create templated replies for processed patches and pull requests
* *b4 diff*: (EXPERIMENTAL) Show range-diff style diffs between patch versions

CONFIGURATION
-------------
B4 configuration is handled via git-config(1), so you can store it in
either the toplevel $HOME/.gitconfig file, or in a per-repository
.git/config file if your workflow changes per project.
Default configuration, with explanations::
[b4]
# Where to look up threads by message id
midmask = https://lore.kernel.org/r/%s'
#
# When recording Link: trailers, use this mask
linkmask = https://lore.kernel.org/r/%s'
#
# When processing thread trailers, use this order. Can use shell-globbing
# and must end with ,*
# Common alternative order:
#trailer-order=link*,fixes*,cc*,reported*,suggested*,original*,co-*,tested*,reviewed*,acked*,signed-off*,*
trailer-order = fixes*,reported*,suggested*,original*,co-*,signed-off*,tested*,reviewed*,acked*,cc*,link*,*
#
# Attestation-checking configuration parameters
# off: do not bother checking attestation
# check: print an attaboy when attestation is found
# softfail: print a warning when no attestation found
# hardfail: exit with an error when no attestation found
attestation-policy = check
#
# "gpg" (whatever gpg is configured to do) or "tofu" to force TOFU mode
# If you don't already have a carefully maintained web of trust setup, it is
# strongly recommended to set this to "tofu"
attestation-trust-model = gpg
#
# How strict should we be when comparing the email address in From to the
# email addresses in the key's UIDs?
# strict: must match one of the uids on the key to pass
# loose: any valid and trusted key will be accepted
attestation-uid-match = loose
#
# When showing attestation check results, do you like "fancy" (color, unicode)
# or simple checkmarks?
attestation-checkmarks = fancy
#
# How long before we consider attestation to be too old?
attestation-staleness-days = 30
#
# You can point this at a non-default home dir, if you like, or leave out to
# use the OS default.
attestation-gnupghome = None
#
# If this is not set, we'll use what we find in
# git-config for gpg.program; and if that's not set,
# we'll use "gpg" and hope for the best
gpgbin = None
#
# How long to keep downloaded threads in cache (minutes)?
cache-expire = 10
# Used when creating summaries for b4 ty, and can be set to a value like
# thanks-commit-url-mask = https://git.kernel.org/username/c/%.10s
# See this page for more info on convenient git.kernel.org shorterners:
# https://korg.wiki.kernel.org/userdoc/git-url-shorterners
thanks-commit-url-mask = None
# See thanks-pr-template.example. If not set, a default template will be used.
thanks-pr-template = None
# See thanks-am-template.example. If not set, a default template will be used.
thanks-am-template = None
