+
+[the skywinder/changelog_test repo]: https://github.com/skywinder/changelog_test/
+[RuboCop]: http://rubocop.readthedocs.io/en/latest/
+
+## Write documentation
+
+This project has documentation in a few places:
+
+### Introduction and usage
+
+A friendly `README.md` written for many audiences.
+
+### Examples and advanced usage
+
+The [wiki].
+
+###  API documentation 
+
+API documentation is written as [YARD] docblocks in the Ruby code.
+
+This is rendered as Web pages on [Rubydoc.info][github-changelog-generator on Rubydoc.info].
+
+The completeness of the API documentation is measured on [our page on the Inch CI website][github-changelog-generator on Inch CI].
+
+### man page
+
+`man/git-generate-changelog.md`
+
+The man page is for the `git generate-changelog` Git sub-command, which is a wrapper for `github_changelog_generator`. That file is a Markdown file.
+
+Use the [ronn] gem to generate `.1` and `.html` artifacts like this: `cd man; ronn git-generate-changelog.md`

-### Changelog generation has never been so easy
-
-**Fully automated changelog generation** - This gem generates a change log file based on **tags**, **issues** and merged **pull requests** (and splits them into separate lists according to labels) from :octocat: GitHub Issue Tracker.
-
-Since you don't have to fill your `CHANGELOG.md` manually now: just run the script, relax and take a cup of :coffee: before your next release! :tada:
-
-### *What’s the point of a change log?*
-
-To make it easier for users and contributors to see precisely what notable changes have been made between each release (or version) of the project.
-
-### *Why should I care?*
-
-Because software tools are for _people_. "Changelogs make it easier for users and
-contributors to see precisely what notable changes have been made between each
-release (or version) of the project."
-
-:arrow_right: *[http://keepachangelog.com](http://keepachangelog.com)*
-
-## Installation
-
-    gem install github_changelog_generator
-
-See also Troubleshooting.
-
-## Output example
-
- Look at **[CHANGELOG.md](https://github.com/skywinder/Github-Changelog-Generator/blob/master/CHANGELOG.md)** for this project
- [ActionSheetPicker-3.0/CHANGELOG.md](https://github.com/skywinder/ActionSheetPicker-3.0/blob/master/CHANGELOG.md)  was generated by command:
-
-      github_changelog_generator -u skywinder -p ActionSheetPicker-3.0
-
- In general, it looks like this:
-
-> ## [1.2.5](https://github.com/skywinder/Github-Changelog-Generator/tree/1.2.5) (2015-01-15)
->
-> [Full Changelog](https://github.com/skywinder/Github-Changelog-Generator/compare/1.2.4...1.2.5)
->
-> **Implemented enhancements:**
->
-> - Use milestone to specify in which version bug was fixed [\#22](https://github.com/skywinder/Github-Changelog-Generator/issues/22)
->
-> **Fixed bugs:**
->
-> - Error when trying to generate log for repo without tags [\#32](https://github.com/skywinder/Github-Changelog-Generator/issues/32)
->
-> **Merged pull requests:**
->
-> - PrettyPrint class is included using lowercase 'pp' [\#43](https://github.com/skywinder/Github-Changelog-Generator/pull/43) ([schwing](https://github.com/schwing))
->
-> - support enterprise github via command line options [\#42](https://github.com/skywinder/Github-Changelog-Generator/pull/42) ([glenlovett](https://github.com/glenlovett))
-
-
-## Usage
-
-  Run this:
-
-      `github_changelog_generator -u github_username -p github_project`
-      `github_changelog_generator  github_username/github_project`
-
- For Github Enterprise repos, specify *both* `--github-site` and `--github-api` options:
-
-      github_changelog_generator --github-site="https://github.yoursite.com" \
-                                 --github-api="https://github.yoursite.com/api/v3/"
-
-This generates a `CHANGELOG.md`, with pretty Markdown formatting.
-
-### Params
-
-Type `github_changelog_generator --help` for details.
-
-For more details about params, read the Wiki page: [**Advanced change log generation examples**](https://github.com/skywinder/github-changelog-generator/wiki/Advanced-change-log-generation-examples)
-
-### Params File
-
-In your project root, you can put a params file named `.github_changelog_generator` to override default params:
-
-Example:
-
-```
-unreleased=false
-future-release=5.0.0
-since-tag=1.0.0
-```
-
-### GitHub token
-
-GitHub only allows 50 unauthenticated requests per hour.
-
-Therefore, it's recommended to run this script with authentication by using a **token**.
-
-Here's how:
-
- [Generate a token here](https://github.com/settings/tokens/new?description=GitHub%20Changelog%20Generator%20token) - you only need "repo" scope for private repositories
- Either:
-    - Run the script with `--token <your-40-digit-token>`; **OR**
-    - Set the `CHANGELOG_GITHUB_TOKEN` environment variable to your 40 digit token
-
-You can set an environment variable by running the following command at the prompt, or by adding it to your shell profile (e.g., `~/.bash_profile` or `~/.zshrc`):
-
-    export CHANGELOG_GITHUB_TOKEN="«your-40-digit-github-token»"
-
-So, if you get a message like this:
-
-``` markdown
-API rate limit exceeded for github_username.
-See: https://developer.github.com/v3/#rate-limiting
-```
-
-It's time to create this token! (Or, wait an hour for GitHub to reset your unauthenticated request limit.)
-
-## Migrating from a manual changelog
-
-Knowing how dedicated you are to your project, you probably haven't been waiting for `github-changelog-generator` to keep a changelog.
-But you probably don't want your project's open issues and PRs for all past features listed in your historic changelog, either.
-
-That's where `--base <your-manual-changelog.md>` comes in handy!
-This option lets append your old manual changelog to the end of the generated entries.
-
-If you have a `HISTORY.md` file in your project, it will automatically be picked as the static historical changelog and appended.
-
-### Rake task
-
-You love `rake`? We do, too! So, we've made it even easier for you:
-we've provided a `rake` task library for your changelog generation.
-
-Configure the task in your `Rakefile`:
-
-```ruby
-require 'github_changelog_generator/task'
-
-GitHubChangelogGenerator::RakeTask.new :changelog do |config|
-  config.since_tag = '0.1.14'
-  config.future_release = '0.2.0'
-end
-```
-
-All command-line options can be passed to the `rake` task as `config`
-parameters. And since you're naming the `rake` task yourself, you can create
-as many as you want.
-
-You can look for params names from the [parser source code (#setup_parser)](https://github.com/skywinder/github-changelog-generator/blob/master/lib/github_changelog_generator/parser.rb). For example, to translate the bugs label to Portuguese, instead of setting `config.bugs_label`, you have to set `config.bug_prefix`, and so on.
-
-## Features and advantages of this project
-
- Generate canonical, neat change log file, followed by [basic change log guidelines](http://keepachangelog.com) :gem:
- Optionally generate **Unreleased** changes (closed issues that have not released yet) :dizzy:
- **GitHub Enterprise support** via command line options! :factory:
- Flexible format **customization**:
-    - **Customize** issues that **should be added** to changelog :eight_spoked_asterisk:
-    - **Custom date formats** supported (but keep [ISO 8601](http://xkcd.com/1179/) in mind!) :date:
-    - Manually specify the version that fixed an issue (for cases when the issue's Closed date doesn't match) by giving the issue's `milestone` the same name as the tag of version :pushpin:
-    - Automatically **exclude specific issues** that are irrelevant to your changelog (by default, any issue labeled `question`, `duplicate`, `invalid`, or `wontfix`) :scissors:
- **Distinguish** issues **by labels**. :mag_right:
-    - Merged pull requests (all merged pull-requests) :twisted_rightwards_arrows:
-    - Bug fixes (issues labeled `bug`) :beetle:
-    - Enhancements (issues labeled `enhancement`) :star2:
-    - Issues (closed issues with no labels) :non-potable_water:
-
- Manually include or exclude issues by labels :wrench:
- Customize lots more! Tweak the changelog to fit your preferences :tophat:

-
-## FAQ
-
- ***I already use GitHub Releases. Why do I need this?***
-
-GitHub Releases is a very good thing. And it's very good practice to maintain it. (Not a lot of people are using it yet!) :congratulations:
-
-*BTW: I would like to support GitHub Releases in [next releases](https://github.com/skywinder/github-changelog-generator/issues/56) ;)*
-
-I'm not trying to compare the quality of handwritten and auto-generated logs. That said....
-
-An auto-generated changelog really helps, even if you manually fill in the release notes!
-
-For example:
-
-When you find a closed bug, it is very useful to know which release fixed it.
-So that you can easily find the issue by \# in `CHANGELOG.md`.
-
- it's not quite as easy to find this in handwritten releases notes
- a generated file saves you the trouble of remembering everything;
-  sometimes people forget to add things to a handwritten file
-
-Ultimately, I think GitHub Releases are ideal for end-users.
-Meanwhile, `CHANGELOG.md` lives right in the repository, with its detailed list of changes, which is handy for developers.
-Finally, there's nothing wrong with using GitHub Releases alongside `CHANGELOG.md` in this combination.
-
- ***I received a warning: "GitHub API rate limit exceed"  What does this mean?***
-
-GitHub [limits the number of API requests](https://developer.github.com/v3/#rate-limiting) you can make in an hour. You can make up to 5,000 requests per hour. For unauthenticated requests, the rate limit is only up to 60 requests per hour. Unauthenticated requests are associated with your IP address (not the user making requests).
-
-If you're seeing this warning, please do the following:
-
-1. Make sure you're providing an OAuth token, so you're not making requests anonymously. Using an OAuth token increases your hourly request maximum from 60 to 5000.
-2. If you have a large repo with lots of issues/PRs, you can use `--max-issues NUM` to limit the number of issues that are pulled back. For example: `--max-issues 1000`
-
- ***My Ruby version is very old, can I use this?***
-
-When your Ruby is old, and you don't want to upgrade, and you want to
-control which libraries you use, you can use Bundler.
-
-In a Gemfile, perhaps in a non-deployed `:development` group, add this
-gem:
-
-```ruby
-group :development do
-  gem 'github_changelog_generator', require: false
-end
-```
-
-Then you can keep back dependencies like rack, which currently is only
-compatible with Ruby >= 2.2.2. So, use an older version for your app by
-adding a line like this to the Gemfile:
-
-```
-gem 'rack', '~> 1.6'
-```
-
-This way, you can keep on using github_changelog_generator, even if you
-can't get the latest version of Ruby installed.

+### Changelog generation has never been so easy
+
+**Fully automated changelog generation** - This gem generates a changelog file based on **tags**, **issues** and merged **pull requests** (and splits them into separate lists according to labels) from :octocat: GitHub Issue Tracker.
+
+Since you don't have to fill your `CHANGELOG.md` manually now: just run the script, relax and take a cup of :coffee: before your next release! :tada:
+
+### *What’s the point of a changelog?*
+
+To make it easier for users and contributors to see precisely what notable changes have been made between each release (or version) of the project.
+
+### *Why should I care?*
+
+Because software tools are for _people_. "Changelogs make it easier for users and
+contributors to see precisely what notable changes have been made between each
+release (or version) of the project."
+
+:arrow_right: *[http://keepachangelog.com](http://keepachangelog.com)*
+
+## Installation
+
+    $ [sudo] gem install github_changelog_generator
+
+See also Troubleshooting.
+
+## Running with Docker
+
+    $ docker run -it --rm -v "$(pwd)":/usr/local/src/your-app skywinder/github-changelog-generator
+
+## Output example
+
+- Look at **[CHANGELOG.md](https://github.com/skywinder/Github-Changelog-Generator/blob/master/CHANGELOG.md)** for this project
+- [ActionSheetPicker-3.0/CHANGELOG.md](https://github.com/skywinder/ActionSheetPicker-3.0/blob/master/CHANGELOG.md)  was generated by command:
+
+      $ github_changelog_generator -u skywinder -p ActionSheetPicker-3.0
+
+- In general, it looks like this:
+
+> ## [1.2.5](https://github.com/skywinder/Github-Changelog-Generator/tree/1.2.5) (2015-01-15)
+>
+> [Full Changelog](https://github.com/skywinder/Github-Changelog-Generator/compare/1.2.4...1.2.5)
+>
+> **Implemented enhancements:**
+>
+> - Use milestone to specify in which version bug was fixed [\#22](https://github.com/skywinder/Github-Changelog-Generator/issues/22)
+>
+> **Fixed bugs:**
+>
+> - Error when trying to generate log for repo without tags [\#32](https://github.com/skywinder/Github-Changelog-Generator/issues/32)
+>
+> **Merged pull requests:**
+>
+> - PrettyPrint class is included using lowercase 'pp' [\#43](https://github.com/skywinder/Github-Changelog-Generator/pull/43) ([schwing](https://github.com/schwing))
+>
+> - support enterprise github via command line options [\#42](https://github.com/skywinder/Github-Changelog-Generator/pull/42) ([glenlovett](https://github.com/glenlovett))
+
+
+## Usage
+
+-  Run this:
+
+	   $ github_changelog_generator -u github_username -p github_project
+	   
+	or, on the 1.14.x (current stable release)
+
+	   $ github_changelog_generator github_username/github_project
+	   
+
+- For Github Enterprise repos, specify *both* `--github-site` and `--github-api` options:
+
+       $ github_changelog_generator --github-site="https://github.yoursite.com" \
+                                  --github-api="https://github.yoursite.com/api/v3/"
+
+This generates a `CHANGELOG.md`, with pretty Markdown formatting.
+
+### Params
+
+Print help for all command-line options to learn more details:
+
+    $ github_changelog_generator --help
+
+For more details about params, read the Wiki page: [**Advanced changelog generation examples**](https://github.com/skywinder/github-changelog-generator/wiki/Advanced-change-log-generation-examples)
+
+### Params File
+
+In your project root, you can put a params file named `.github_changelog_generator` to override default params:
+
+Example:
+
+```
+unreleased=false
+future-release=5.0.0
+since-tag=1.0.0
+```
+
+### GitHub token
+
+GitHub only allows 50 unauthenticated requests per hour.
+
+Therefore, it's recommended to run this script with authentication by using a **token**.
+
+Here's how:
+
+- [Generate a token here](https://github.com/settings/tokens/new?description=GitHub%20Changelog%20Generator%20token) - you only need "repo" scope for private repositories
+- Either:
+    - Run the script with `--token <your-40-digit-token>`; **OR**
+    - Set the `CHANGELOG_GITHUB_TOKEN` environment variable to your 40 digit token
+
+You can set an environment variable by running the following command at the prompt, or by adding it to your shell profile (e.g., `~/.bash_profile` or `~/.zshrc`):
+
+    export CHANGELOG_GITHUB_TOKEN="«your-40-digit-github-token»"
+
+So, if you get a message like this:
+
+``` markdown
+API rate limit exceeded for github_username.
+See: https://developer.github.com/v3/#rate-limiting
+```
+
+It's time to create this token! (Or, wait an hour for GitHub to reset your unauthenticated request limit.)
+
+## Migrating from a manual changelog
+
+Knowing how dedicated you are to your project, you probably haven't been waiting for `github-changelog-generator` to keep a changelog.
+But you probably don't want your project's open issues and PRs for all past features listed in your historic changelog, either.
+
+That's where `--base <your-manual-changelog.md>` comes in handy!
+This option lets append your old manual changelog to the end of the generated entries.
+
+If you have a `HISTORY.md` file in your project, it will automatically be picked as the static historical changelog and appended.
+
+### Rake task
+
+You love `rake`? We do, too! So, we've made it even easier for you:
+we've provided a `rake` task library for your changelog generation.
+
+Configure the task in your `Rakefile`:
+
+```ruby
+require 'github_changelog_generator/task'
+
+GitHubChangelogGenerator::RakeTask.new :changelog do |config|
+  config.since_tag = '0.1.14'
+  config.future_release = '0.2.0'
+end
+```
+
+All command-line options can be passed to the `rake` task as `config`
+parameters. And since you're naming the `rake` task yourself, you can create
+as many as you want.
+
+You can look for params names from the [parser source code (#setup_parser)](https://github.com/skywinder/github-changelog-generator/blob/master/lib/github_changelog_generator/parser.rb). For example, to translate the bugs label to Portuguese, instead of setting `config.bugs_label`, you have to set `config.bug_prefix`, and so on.
+
+## Features and advantages of this project
+
+- Generate canonical, neat changelog file, followed by [basic changelog guidelines](http://keepachangelog.com) :gem:
+- Optionally generate **Unreleased** changes (closed issues that have not released yet) :dizzy:
+- **GitHub Enterprise support** via command line options! :factory:
+- Flexible format **customization**:
+    - **Customize** issues that **should be added** to changelog :eight_spoked_asterisk:
+    - **Custom date formats** supported (but keep [ISO 8601](http://xkcd.com/1179/) in mind!) :date:
+    - Manually specify the version that fixed an issue (for cases when the issue's Closed date doesn't match) by giving the issue's `milestone` the same name as the tag of version :pushpin:
+    - Automatically **exclude specific issues** that are irrelevant to your changelog (by default, any issue labeled `question`, `duplicate`, `invalid`, or `wontfix`) :scissors:
+- **Distinguish** issues **by labels**. :mag_right:
+    - Merged pull requests (all merged pull-requests) :twisted_rightwards_arrows:
+    - Bug fixes (issues labeled `bug`) :beetle:
+    - Enhancements (issues labeled `enhancement`) :star2:
+    - Issues (closed issues with no labels) :non-potable_water:
+
+- Manually include or exclude issues by labels :wrench:
+- Customize lots more! Tweak the changelog to fit your preferences :tophat:
+(*See `github_changelog_generator --help`  for details)*

+
+## Am I missing some essential feature?
+
+- **Nothing is impossible!**
+
+- Open an [issue](https://github.com/skywinder/Github-Changelog-Generator/issues/new) and let's make the generator better together!
+
+- *Bug reports, feature requests, patches, and well-wishes are always welcome.* :heavy_exclamation_mark:
+
+## FAQ
+
+- ***I already use GitHub Releases. Why do I need this?***
+
+GitHub Releases is a very good thing. And it's very good practice to maintain it. (Not a lot of people are using it yet!) :congratulations:
+
+*BTW: I would like to support GitHub Releases in [next releases](https://github.com/skywinder/github-changelog-generator/issues/56) ;)*
+
+I'm not trying to compare the quality of handwritten and auto-generated logs. That said....
+
+An auto-generated changelog really helps, even if you manually fill in the release notes!
+
+For example:
+
+When you find a closed bug, it is very useful to know which release fixed it.
+So that you can easily find the issue by \# in `CHANGELOG.md`.
+
+- It's not quite as easy to find this in handwritten releases notes.
+- A generated file saves you the trouble of remembering everything;
+  sometimes people forget to add things to a handwritten file.
+
+Ultimately, I think GitHub Releases are ideal for end-users.
+Meanwhile, `CHANGELOG.md` lives right in the repository, with its detailed list of changes, which is handy for developers.
+Finally, there's nothing wrong with using GitHub Releases alongside `CHANGELOG.md` in this combination.
+
+- ***I got an "API rate limit exceeded" error message. What does this mean?***
+
+GitHub [limits the number of API requests](https://developer.github.com/v3/#rate-limiting) you can make in an hour. You can make up to 5,000 requests per hour. For unauthenticated requests, the rate limit is only up to 60 requests per hour. Unauthenticated requests are associated with your IP address (not the user making requests).
+
+If you're seeing this warning, please do the following:
+
+1. Make sure you're providing an OAuth token, so you're not making requests anonymously. Using an OAuth token increases your hourly request maximum from 60 to 5000.
+2. If you have a large repo with lots of issues/PRs, you can use `--max-issues NUM` to limit the number of issues that are pulled back. For example: `--max-issues 1000`
+
+- ***My Ruby version is very old, can I use this?***
+
+When your Ruby is old, and you don't want to upgrade, and you want to
+control which libraries you use, you can use Bundler.
+
+In a Gemfile, perhaps in a non-deployed `:development` group, add this
+gem:
+
+```ruby
+group :development do
+  gem 'github_changelog_generator', require: false
+end
+```
+
+Then you can keep back dependencies like rack, which currently is only
+compatible with Ruby >= 2.2.2. So, use an older version for your app by
+adding a line like this to the Gemfile:
+
+```
+gem 'rack', '~> 1.6'
+```
+
+This way, you can keep on using github_changelog_generator, even if you
+can't get the latest version of Ruby installed.

Eric Putnam	587557e1ac	Refactor generation code and allow custom sections There's a lot in this PR. - Added a Section class to more easily make the other changes and hopefully add flexibility for the future - Added an option called `configure_sections` that allows you create your own custom sections. It blows away all other sections and uses only the ones you give it. - Added an option called `add_sections` that allows you to add_sections to the default section set - Added an option called `include_merged` that can be used when configure_sections is defined. Configure sections blows away any and all default sections so to get this one back, you have to set this option. - Added tests for this stuff @HAIL9000 was a co-author. Because of a little git snafu, I accidentally squashed all of our work into one so it looks like it was just me. --- Refactor details: Before this change, the code in generator.rb and generator_generation.rb was conflated and method call flow went back and forth between the two files seemingly randomly. They also both defined the exact same class, which is un-ruby-ish. I tried to separate methods used for the whole changelog generation from methods used for specific parts of the changelog and move them into specific classes. I reasoned that a changelog is a series of "entries" of all tagged releases plus an extra entry for the unreleased entry. Each entry is comprised of a header and a series of "sections" for that entry. Each section is comprized of a list of issues and/or pull requests for that entry. So the log contains entries, entries contain sections, and sections contain issues & prs. I have structured the classes around this idea. - lib/github_changelog_generator/generator/generator.rb is for code related to generating the entire changelog. - lib/github_changelog_generator/generator/entry.rb is for code related to generating entries. - lib/github_changelog_generator/generator/section.rb is for code relating to geneating entry sections. Issues and PRs are already special objects, so it doesn't make sense to break those out into their own class.	2017-12-14 16:13:41 -08:00
