问题 We have 2 versions of a text T before and after, before: a\nb\n after: b\n define regex ^[^\n].*\n$ as Line, define operation delete_line of deleting a substring that match Line from a text, define operation add_line of adding a substring that match Line from a text, Obviously, T can transform with operation delete_line . is there a library that give a general solution of this problem? Given a set of regex ,it will calculate if the text can transform before to after. 来源： https://stackoverflow

Create diff patch for a composer package

阅读更多关于 Create diff patch for a composer package

问题 I'm contributing to quite a large project with lots of submodules, and using repositories section of composer.json etc. Sometimes it is handy to edit files in the vendor directory instead of the real repository (e.g. there are some submodules with tests for the other ones). Then I use composer update and a message pops up: Discard changes [y,n,v,d,s,?]? I can choose the option d , thus getting a nice diff patch I can later use for the real Git repository. Can I have such a patch in a simpler

Unable to diff dot-files in Mac's FileMerge

阅读更多关于 Unable to diff dot-files in Mac's FileMerge

问题 I have set my FileMerge not to ignore any file. However, it ignores my dotFiles. How can you make FileMerge to diff dotFiles? 回答1: Since the leading dot is merely a conventional hint to the OS that the file is hidden (inherited from UNIX) I would imagine that removing the leading dot from the filename would allow the utility to see and diff the files. 回答2: You need to use opendiff -Mac's builtIn command to launch dotFiles in FileMerge. You can find a solution at the thread. 来源： https:/

How can I determine if a given DTD a subset of another?

阅读更多关于 How can I determine if a given DTD a subset of another?

问题 I need to verify that a "simplified" DTD is really a subset of a larger DTD, I.e. that documents that are valid according to the "simplified" DTD will also always be valid according to the larger (or "master") DTD. The simplified DTD is being written now -- it's derived from the master DTD (were it the other way around, one could simply include the smaller DTD into the larger one). How would I be able to determine if the simplified DTD is derived from the master DTD? 回答1: DTDs are really just

Are there any tools that can do the equivalent of a “git diff” with images (to see what's changed?)

阅读更多关于 Are there any tools that can do the equivalent of a “git diff” with images (to see what's changed?)

问题 I'm trying to figure out a way to more rapidly determine where new construction is happening by comparing annual satellite imagery. In Google Earth, you can roll back the clock on satellite imagery, for whatever reason, and determine what has changed over the years. One thing thats interesting is you can determine new construction. Currently, I'm doing it manually which is very slow. I know satellite photos can vary greatly due to weather, photo exposure variations, seasonal changes, etcetera

How to find commit responsible by adding a file index (blob)

阅读更多关于 How to find commit responsible by adding a file index (blob)

问题 When we make a git diff Version1..Version2 -- file , this command will return something like : diff --git a/wp-includes/version.php b/wp-includes/version.php index 5d034bb9d8..617021e8d9 100644 The git here compare between two version of a file to give you the difference between them. I need to know the commit responsible for adding the file in question from the number of index 5d034bb9d8 , and the index **617021e8d9*. 回答1: TL;DR This (untested) script may do what you want.
