Darcs记录空补丁

Question

我正在编写一个存储库转换工具。问题就在于这件事。Git可以有空提交；Darcs不能。对于空的Mercurial提交，我刚刚创建了一个标记。我知道Darcs有标记，但我不知道如何从消息中删除标记前缀。

Answer 1

您可以通过创建一个非空修补程序，然后使用amend-record向其添加反向更改，从而使Darcs生成一个空修补程序：

ganesh@scafell ~/temp/1
$ touch foo

ganesh@scafell ~/temp/1
$ darcs add foo
Adding 'foo'

ganesh@scafell ~/temp/1
$ darcs rec
addfile ./foo
Shall I record this change? (1/1)  [ynW...], or ? for more options: y
Do you want to record these changes? [Yglqk...], or ? for more options: y
What is the patch name? foo
Finished recording patch 'foo'

ganesh@scafell ~/temp/1
$ rm foo

ganesh@scafell ~/temp/1
$ darcs amend
Wed May 28 06:49:22 GMT Daylight Time 2014  Ganesh Sittampalam <ganesh@earth.li>
  * foo
Shall I amend this patch? [yNjk...], or ? for more options: y
rmfile ./foo
Shall I record this change? (1/1)  [ynW...], or ? for more options: y
Do you want to record these changes? [Yglqk...], or ? for more options: y
