## Format
##
## ACTION: [AUDIENCE:] COMMIT_MSG
##
## Description
##
## ACTION is one of 'chg', 'fix', 'new', 'rem', 'sec'
##
## Is WHAT the change is about.
##
## 'chg' is for refactor, small improvement, cosmetic changes...
## 'fix' is for bug fixes
## 'new' is for new features, big improvement
## 'rem' is for removed features
## 'sec' is for security fixes
##
## Each MR title should have exactly one ACTION, and no non-merge commits should have these.
##
## AUDIENCE is optional and can be 'dev', 'usr', 'pkg', 'test', 'doc'
##
## Is WHO is concerned by the change.
##
## Included in release notes and changelog:
## 'usr' is for final users
## 'pkg' is for packagers
##
## Included in changelog:
## 'dev' is for developers
##
## Omitted from changelog:
## 'test' is for test-only changes
## 'doc' is for doc-only changes
##
## COMMIT_MSG is ... well ... the commit message itself.
##
##
## Examples:
##
## If you want to add a release note, mark it for usr or pkg audience:
##
## sec: usr: Fix CVE-YYYY-NNNN
## rem: usr: Deprecate feature xyz
## new: pkg: libngtcp2 is now required
##
## If you want to mention it just in the changelog, add dev audience:
##
## chg: dev: Refactor xyz
## fix: dev: Fix a rare edge case of xyz
## new: dev: Add new QTYPE
##
## If you don't specify audience context, or use a custom one, it won't end
## up in the changelog:
##
## chg: doc: Tidy up the docs
## fix: test: Fix a broken test
## chg: Do some cleanup
## sec: test: Add a test case for CVE-YYYY-NNNN
##
## Please note that multi-line commit messages are supported; only the first
## line will be considered as the "summary" of the commit message. So tags
## and other rules only apply to the summary. The body of the commit
## message will be displayed in the changelog without reformatting.
##
## ``ignore_regexps`` is a line of regexps
##
## Any commit having its full commit message matching any regexp listed here
## will be ignored and won't be reported in the changelog.
##
ignore_regexps = [
r"^$", ## ignore commits with empty messages
]
## ``section_regexps`` is a list of 2-tuples associating a string label and a
## list of regexp
##
## Commit messages will be classified in sections thanks to this. Section
## titles are the label, and a commit is classified under this section if any
## of the regexps associated is matching.
##
## Please note that ``section_regexps`` will only classify commits and won't
## make any changes to the contents. So you'll probably want to go check
## ``subject_process`` (or ``body_process``) to do some changes to the subject,
## whenever you are tweaking this variable.

## ``body_process`` is a callable
##
## This callable will be given the original body and result will
## be used in the changelog.
##
## Available constructs are:
##
## - any python callable that take one txt argument and return txt argument.
##
## - ReSub(pattern, replacement): will apply regexp substitution.
##
## - Indent(chars=" "): will indent the text with the prefix
## Please remember that template engines gets also to modify the text and
## will usually indent themselves the text if needed.
##
## - Wrap(regexp=r"\n\n"): re-wrap text in separate paragraph to fill 80-Columns
##
## - noop: do nothing
##
## - ucfirst: ensure the first letter is uppercase.
## (usually used in the ``subject_process`` pipeline)
##
## - final_dot: ensure text finishes with a dot
## (usually used in the ``subject_process`` pipeline)
##
## - strip: remove any spaces before or after the content of the string
##
## - SetIfEmpty(msg="No commit message."): will set the text to
## whatever given ``msg`` if the current text is empty.
##
## Additionally, you can `pipe` the provided filters, for instance:
# body_process = Wrap(regexp=r'\n(?=\w+\s*:)') | Indent(chars=" ")
# body_process = Wrap(regexp=r'\n(?=\w+\s*:)')
# body_process = noop
body_process = (
ReSub(r"\n*See merge request isc-private/bind9!\d+", r"")
| ReSub(r"https://gitlab.isc.org/isc-projects/bind9/-/issues/", r"#")
| ReSub(r"https://gitlab.isc.org/isc-projects/bind9/-/merge_requests/", r"!")
| ReSub(r"\n*Backport of [^\n]+", r"")
| ReSub(r"\n*(Replaces|Supersedes)[^\n]+", r"")
| ReSub(
r"\n*(Closes|Fixes|Related|See):?\s*(isc-projects/bind9)?((#|!)\d+)",
r" :gl:`\3`",
)
| ReSub(r"\n*Merge branch '[^']+' into [^\n]+", r"")
| ReSub(r"\n*See merge request isc-projects/bind9(!\d+)", r" :gl:`\1`")
| Wrap(regexp="\n\n", separator="\n\n")
| strip
)
## ``subject_process`` is a callable
##
## This callable will be given the original subject and result will
## be used in the changelog.
##
## Available constructs are those listed in ``body_process`` doc.
subject_process = (
strip
| ReSub(
r"^(\[9\.[0-9]{2}(-S)?\])?\s*(\[[^]]*\]\s*)?(chg|fix|new|rem|sec):\s*((dev|usr|pkg)\s*:\s*)?([^\n]*)$",
r"\3\7",
)
| SetIfEmpty("No commit message.")
| ucfirst
| final_dot
)
## ``tag_filter_regexp`` is a regexp
##
## Tags that will be used for the changelog must match this regexp.
##
tag_filter_regexp = r"^v9\.[0-9]+\.[0-9]+(-S[0-9]+)?$"
## ``unreleased_version_label`` is a string or a callable that outputs a string
##
## This label will be used as the changelog Title of the last set of changes
## between last valid tag and HEAD if any.
unreleased_version_label = "(-dev)"
## ``include_commit_sha`` is a boolean to indicate whether the sha of the
## commit should be included in the change
include_commit_sha = True
## ``output_engine`` is a callable
##
## This will change the output format of the generated changelog file
##
## Available choices are:
##
## - rest_py
##
## Legacy pure python engine, outputs ReSTructured text.
## This is the default.
##
## - mustache(<template_name>)
##
## Template name could be any of the available templates in
## ``templates/mustache/*.tpl``.
## Requires python package ``pystache``.
## Examples:
## - mustache("markdown")
## - mustache("restructuredtext")
##
## - makotemplate(<template_name>)
##
## Template name could be any of the available templates in
## ``templates/mako/*.tpl``.
## Requires python package ``mako``.
## Examples:
## - makotemplate("restructuredtext")
##
output_engine = rest_py
# output_engine = mustache("restructuredtext")
# output_engine = mustache("markdown")
# output_engine = makotemplate("restructuredtext")
## ``include_merge`` is a boolean
##
## This option tells git-log whether to include merge commits in the log.
## The default is to include them.
include_merge = True
## ``log_encoding`` is a string identifier
##
## This option tells gitchangelog what encoding is outputed by ``git log``.
## The default is to be clever about it: it checks ``git config`` for
## ``i18n.logOutputEncoding``, and if not found will default to git's own
## default: ``utf-8``.
# log_encoding = 'utf-8'
## ``publish`` is a callable
##
## Sets what ``gitchangelog`` should do with the output generated by
## the output engine. ``publish`` is a callable taking one argument
## that is an interator on lines from the output engine.
##
## Some helper callable are provided:
##
## Available choices are:
##
## - stdout
##
## Outputs directly to standard output
## (This is the default)
##
## - FileInsertAtFirstRegexMatch(file, pattern, idx=lamda m: m.start())
##
## Creates a callable that will parse given file for the given
## regex pattern and will insert the output in the file.
## ``idx`` is a callable that receive the matching object and
## must return a integer index point where to insert the
## the output in the file. Default is to return the position of
## the start of the matched string.
##
## - FileRegexSubst(file, pattern, replace, flags)
##
## Apply a replace inplace in the given file. Your regex pattern must
## take care of everything and might be more complex. Check the README
## for a complete copy-pastable example.
##
# publish = FileInsertIntoFirstRegexMatch(
# "CHANGELOG.rst",
# r'/(?P<rev>[0-9]+\.[0-9]+(\.[0-9]+)?)\s+\([0-9]+-[0-9]{2}-[0-9]{2}\)\n--+\n/',
# idx=lambda m: m.start(1)
# )
publish = stdout
## ``revs`` is a list of callable or a list of string
##
## callable will be called to resolve as strings and allow dynamical
## computation of these. The result will be used as revisions for
## gitchangelog (as if directly stated on the command line). This allows
## to filter exaclty which commits will be read by gitchangelog.
##
## To get a full documentation on the format of these strings, please
## refer to the ``git rev-list`` arguments. There are many examples.
##
## Using callables is especially useful, for instance, if you
## are using gitchangelog to generate incrementally your changelog.
##
## Some helpers are provided, you can use them::
##
## - FileFirstRegexMatch(file, pattern): will return a callable that will
## return the first string match for the given pattern in the given file.
## If you use named sub-patterns in your regex pattern, it'll output only
## the string matching the regex pattern named "rev".
##
## - Caret(rev): will return the rev prefixed by a "^", which is a
## way to remove the given revision and all its ancestor.
##
## Please note that if you provide a rev-list on the command line, it'll
## replace this value (which will then be ignored).
##
## If empty, then ``gitchangelog`` will act as it had to generate a full
## changelog.
##
## The default is to use all commits to make the changelog.
# revs = ["^1.0.3", ]
# revs = [
# Caret(
# FileFirstRegexMatch(
# "CHANGELOG.rst",
# r"(?P<rev>[0-9]+\.[0-9]+(\.[0-9]+)?)\s+\([0-9]+-[0-9]{2}-[0-9]{2}\)\n--+\n")),
# "HEAD"
# ]
revs = []
