获取Rails项目中包含的所有gem的更改日志

时间：2012-02-27 18:37:14

标签： ruby ruby-on-rails-3 rubygems gem bundler

我有一个使用bundler的Rails项目。我所包含的许多宝石都是最新版本背后的很多版本。我知道我可以伸出手指并运行bundle update以获取最新版本，考虑到依赖关系，但这可能会破坏我的应用程序中依赖于已弃用的gem方法的部分，并且可能不会值得努力。

有没有办法在Gemfile.lock中的版本集和rubygems上的最新版本之间获取所有捆绑宝石的更改日志？这似乎是一个相当普遍的需求，但我没有＆找不到任何解决方案......

4 个答案:

答案 0 :(得分：6)

这是一个非常好的主意。我还没有听说过任何当前工具，所以我创建了一个可以执行此操作的脚本。

这是非常hacky / alpha，但它仍然非常有效（比我开始编写时更多）。因此使用风险自负。希望尽管像这样的功能（但有很大改进）最终可能会成为捆绑器。

要使用，请先提交所有更改。然后在基目录中运行脚本（Gemfile.lock文件所在的位置。

它将首先查询所有正在使用的宝石以查找其更改日志。然后它将运行bundle update。然后它将查询所有宝石，找到新宝石并区分更改日志。最后，它将运行git checkout Gemfile.lock和bundle install以还原由bundle update命令引起的任何更改。结果将保存在文件bundler_gem_diff.txt中。

        return nil

    changelogs.first.chomp

以下是我在octopress博客安装上运行它的输出（相当长，主要是因为kramdown使用git log作为更改日志）：

< ## 3.1.0 (Unreleased)
---
> ## 3.1.11
> 
> * Allow control directives (such as `@if`) to be nested beneath properties.
> * Allow property names to begin with a hyphen followed by interpolation (e.g. `-#{...}`).
> * Fix a parsing error with interpolation in comma-separated lists.
> * Make `--cache-store` with with `--update`.
> * Properly report `ArgumentError`s that occur within user-defined functions.
> * Don't crash on JRuby if the underlying Java doesn't support every Unicode encoding.
> * Add new `updated_stylesheet` callback, which is run after each stylesheet has
>   been successfully compiled. Thanks to [Christian Peters](https://github.com/ChristianPeters).
> * Allow absolute paths to be used in an importer with a different root.
> * Don't destructively modify the options when running `Sass::Plugin.force_update`.
> 
> ### Deprecations -- Must Read!
> 
> * The `updating_stylesheet` is deprecated and will be removed in a
>   future release. Use the new `updated_stylesheet` callback instead.
> 
> ## 3.1.10
> 
> * Fix another aspect of the 3.1.8 regression relating to `+`.
> 
> ## 3.1.9
> 
> * Fix a regression in 3.1.8 that broke the `+` combinator in selectors.
> 
> * Deprecate the loud-comment flag when used with silent comments (e.g. `//!`).
>   Using it with multi-line comments (e.g. `/*!`) still works.
> 
> ## 3.1.8
> 
> * Deprecate parent selectors followed immediately by identifiers (e.g. `&foo`).
>   This should never have worked, since it violates the rule
>   of `&` only being usable where an element selector would.
> 
> * Add a `--force` option to the `sass` executable which makes `--update`
>   always compile all stylesheets, even if the CSS is newer.
> 
> * Disallow semicolons at the end of `@import` directives in the indented syntax.
> 
> * Don't error out when being used as a library without requiring `fileutil`.
> 
> * Don't crash when Compass-style sprite imports are used with `StalenessChecker`
>   (thanks to [Matthias Bauer](https://github.com/moeffju)).
> 
> * The numeric precision of numbers in Sass can now be set using the
>   `--precision` option to the command line. Additionally, the default
>   number of digits of precision in Sass output can now be
>   changed by setting `Sass::Script::Number.precision` to an integer
>   (defaults to 3). Since this value can now be changed, the `PRECISION`
>   constant in `Sass::Script::Number` has been deprecated. In the unlikely
>   event that you were using it in your code, you should now use
>    `Sass::Script::Number.precision_factor` instead.
> 
> * Don't crash when running `sass-convert` with selectors with two commas in a row.
> 
> * Explicitly require Ruby >= 1.8.7 (thanks [Eric Mason](https://github.com/ericmason)).
> 
> * Properly validate the nesting of elements in imported stylesheets.
> 
> * Properly compile files in parent directories with `--watch` and `--update`.
> 
> * Properly null out options in mixin definitions before caching them. This fixes
>   a caching bug that has been plaguing some Rails 3.1 users.
> 
> ## 3.1.7
> 
> * Don't crash when doing certain operations with `@function`s.
> 
> ## 3.1.6
> 
> * The option `:trace_selectors` can now be used to emit a full trace
>   before each selector. This can be helpful for in-browser debugging of
>   stylesheet imports and mixin includes. This option supersedes the
>   `:line_comments` option and is superseded by the `:debug_info`
>   option.
> 
> * Fix a bug where long `@if`/`@else` chains would cause exponential slowdown
>   under some circumstances.
> 
> ## 3.1.5
> 
> * Updated the vendored FSSM version, which will avoid segfaults on OS
>   X Lion when using `--watch`.
> 
> ## 3.1.4
> 
> * Sass no longer unnecessarily caches the sass options hash.
>   This allows objects that cannot be marshaled to be placed into the
>   options hash.
> 
> ## 3.1.3
> 
> * Sass now logs message thru a logger object which can be changed to
>   provide integration with other frameworks' logging infrastructure.
> 
> 
> ## 3.1.2
> 
> * Fix some issues that were breaking Sass when running within Rubinius.
> * Fix some issues that were affecting Rails 3.1 integration.
> * New function `zip` allows several lists to be combined into one
>   list of lists. For example:
>   `zip(1px 1px 3px, solid dashed solid, red green blue)` becomes
>   `1px solid red, 1px dashed green, 3px solid blue`
> * New function `index` returns the list index of a value
>   within a list. For example: `index(1px solid red, solid)`
>   returns `2`. When the value is not found `false` is returned.
> 
> ## 3.1.1
> 
> * Make sure `Sass::Plugin` is loaded at the correct time in Rails 3.
> 
> ## 3.1.0

这并不能完全回答您的问题，但了解Gem版本号的工作原理可能会有所帮助。根据规范，gem版本中的三个数字中的第一个应告诉您宝石是否保证向后兼容。

例如，如果您使用某个gem版本3.1.0启动项目，它应该与任何3.x.x版本的gem兼容。根据规范，“类别3更改（不兼容）将增加主要版本号并重置次要和构建数字”

详情请见此处：http://docs.rubygems.org/read/chapter/7

您可能还会发现有关冻结宝石版本的帖子，以测试有用的新版本：https://stackoverflow.com/a/2147227/834512

新bundle outdated命令是否符合您的需求？

http://patshaughnessy.net/2011/11/5/besides-being-faster-what-else-is-new-in-bundler-1-1

  

Bundler 1.1中引入的最有用和最重要的新命令是bundle outdated，它将识别你的bundle中过时的gem - 这些是有更新版本的gems

还有一个很好的Web服务，可以免费用于公共开源项目（可用github服务挂钩）：http://Gemnasium.com

它会检查哪些宝石是最新的，并提供概述以及有关版本之间发生变化的电子邮件通知（github标记比较差异）。
