## Format
##
##   ACTION: [AUDIENCE:] COMMIT_MSG [!TAG ...]
##
## Description
##
##   ACTION is one of 'chg', 'fix', 'new'
##
##       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
##
##   AUDIENCE is optional and one of 'dev', 'usr', 'pkg', 'test', 'doc'
##
##       Is WHO is concerned by the change.
##
##       'dev'  is for developpers (API changes, refactors...)
##       'usr'  is for final users (UI changes)
##       'pkg'  is for packagers   (packaging changes)
##       'test' is for testers     (test only related changes)
##       'doc'  is for doc guys    (doc only changes)
##
##   COMMIT_MSG is ... well ... the commit message itself.
##
##   TAGs are additionnal adjective as 'refactor' 'minor' 'cosmetic'
##
##       They are preceded with a '!' or a '@' (prefer the former, as the
##       latter is wrongly interpreted in github.) Commonly used tags are:
##
##       'refactor' is obviously for refactoring code only
##       'minor' is for a very meaningless change (a typo, adding a comment)
##       'cosmetic' is for cosmetic driven change (re-indentation, 80-col...)
##       'wip' is for partial functionality but complete subfunctionality.
##
## Example:
##
##   new: usr: support of bazaar implemented
##   chg: re-indentend some lines !cosmetic
##   new: dev: updated code to be compatible with last version of killer lib.
##   fix: pkg: updated year of licence coverage.
##   new: test: added a bunch of test around user usability of feature X.
##   fix: typo in spelling my name in comment. !minor
##
##   Please note that multi-line commit message are supported, and only the
##   first line will be considered as the "summary" of the commit message. So
##   tags, and other rules only applies 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'@minor', r'!minor',
    r'@cosmetic', r'!cosmetic',
    r'@refactor', r'!refactor',
    r'@wip', r'!wip',
    r'^([cC]hg|[fF]ix|[nN]ew)\s*:\s*[p|P]kg:',
    r'^([cC]hg|[fF]ix|[nN]ew)\s*:\s*[d|D]ev:',
    r'^(.{3,3}\s*:)?\s*[fF]irst commit.?\s*$',
    r'^$',  ## 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.
##
section_regexps = [
    ('New', [
        r'^[nN]ew\s*:\s*((dev|use?r|pkg|test|doc)\s*:\s*)?([^\n]*)$',
     ]),
    ('Changes', [
        r'^[cC]hg\s*:\s*((dev|use?r|pkg|test|doc)\s*:\s*)?([^\n]*)$',
     ]),
    ('Fix', [
        r'^[fF]ix\s*:\s*((dev|use?r|pkg|test|doc)\s*:\s*)?([^\n]*)$',
     ]),

    ('Other', None ## Match all lines
     ),

]


## ``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)[A-Z]\w+(-\w+)*: .*(\n\s+.*)*)+$', r'') | 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'^([cC]hg|[fF]ix|[nN]ew)\s*:\s*((dev|use?r|pkg|test|doc)\s*:\s*)?([^\n@]*)(@[a-z]+\s+)*$', r'\4') |
    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'^[0-9]+\.[0-9]+(\.[0-9]+)?$'
tag_filter_regexp = r'^v[0-9]+\.[0.9]+(\.[0-9]+)?$'

## ``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 = "Unreleased"

## ``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.
# Including merge commit to be able to detect which group of commits belong
# to the same feature/bug.
include_merge = False


## ``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(), flags)
##
##        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 = FileInsertAtFirstRegexMatch(
    "CHANGELOG.rst",
    r"(?P<rev>v[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>v[0-9]+\.[0-9]+(\.[0-9]+)?)\s+\([0-9]+-[0-9]{2}-[0-9]{2}\)\n--+\n")),
