        git-code-debt
        =============
        
        A dashboard for monitoring code debt in a git repository.
        
        
        ## Installation
        
        `pip install git-code-debt`
        
        
        ## Usage
        
        
        ### Basic / tl;dr Usage
        
        #### make a `generate_config.yaml`
        
        ```yaml
        # required: repository to clone (can be anything `git clone` understands) even
        # a repository already on disk
        repo: git@github.com:asottile/git-code-debt
        
        # required: database generation path
        database: database.db
        
        # optional: default False
        skip_default_metrics: false
        
        # optional: default []
        metric_package_names: []
        
        # optional: default ^$ (python regex) to exclude paths such as '^vendor/'
        exclude: ^$
        ```
        
        #### invoke the cli
        
        ```
        # Generate code metric data (substitute your own repo path)
        $ git-code-debt-generate
        # Start the server
        $ git-code-debt-server database.db
        ```
        
        ### Updating data on an existing database
        
        Adding data to the database is as simple as running generate again.
        `git-code-debt` will pick up in the git history from where data was generated
        previously.
        
        ```
        $ git-code-debt-generate
        ```
        
        ### Creating your own metrics
        
        1. Create a python project which adds `git-code-debt` as a dependency.
        2. Create a package where you'll write your metrics
        3. Add your package to `metric_package_names` in your `generate_config.yaml`
        
        
        The simplest way to write your own custom metrics is to extend
        `git_code_debt.metrics.base.SimpleLineCounterBase`
        
        
        Here's what the base class looks like
        
        ```python
        
        class SimpleLineCounterBase(DiffParserBase):
            # ...
        
            def should_include_file(self, file_diff_stat):
                """Implement me to return whether a filename should be included.
                By default, this returns True.
        
                :param FileDiffStat file_diff_stat:
                """
                return True
        
            def line_matches_metric(self, line, file_diff_stat):
                """Implement me to return whether a line matches the metric.
        
                :param bytes line: Line in the file
                :param FileDiffStat file_diff_stat:
                """
                raise NotImplementedError
        ```
        
        Here's an example metric
        
        ```python
        from git_code_debt.metrics.base import SimpleLineCounterBase
        
        
        class Python__init__LineCount(SimpleLineCounterBase):
            """Counts the number of lines in __init__.py"""
        
            def should_include_file(self, file_diff_stat):
                return file_diff_stat.filename == b'__init__.py'
        
            def line_matches_metric(self, line, file_diff_stat):
                # All lines in __init__.py match
                return True
        ```
        
        More complex metrics can extend `DiffParserBase`
        
        ```python
        class DiffParserBase(object):
            # Specify __metric__ = False to not be included (useful for base classes)
            __metric__ = False
        
            def get_metrics_from_stat(self, commit, file_diff_stats):
                """Implement me to yield Metric objects from the input list of
                FileStat objects.
        
                Args:
                    commit - Commit object
                    file_diff_stats - list of FileDiffStat objects
        
                Returns:
                   generator of Metric objects
                """
                raise NotImplementedError
        
            def get_metrics_info(self):
                """Implement me to yield `MetricInfo` objects."""
                raise NotImplementedError
        ```
