问题 I use Vim. I open a file. I edit it and I want to see what I've edited before I save it. How can I do this in Vim? 回答1: http://vim.wikia.com/wiki/Diff_current_buffer_and_the_original_file Here is a function and command to see a diff between the currently edited file and its unmodified version in the filesystem.

问题 I would like to integrate Beyond Compare with ClearCase so that I can use it for diffing and merging files, instead of the awful tools provided by ClearCase. Does anyone have instructions for performing this integration? 回答1: As mentioned in my previous answer, just modify the map file located in: # up to ClearCase 7.0 c:\program files\rational\ClearCase\lib\mgrs or # ClearCase 7.1 and more c:\program files\IBM\RationalSDLC\ClearCase\lib\mgrs Each map line has 3 parts: the CC filetype, the CC

问题 When I do git diff COMMIT I see the changes between that commit and HEAD (as far as I know), but I would like to see the changes that were made by that single commit. I haven't found any obvious options on diff / log that will give me that output. 回答1: To see the diff for a particular COMMIT hash: git diff COMMIT~ COMMIT will show you the difference between that COMMIT 's ancestor and the COMMIT . See the man pages for git diff for details about the command and gitrevisions about the ~

问题 This has been bugging me for a while and searching has yielded no hints. Issue: When I do a git diff on a PHP file containing a Class , each hunk description has the class name with no mention of the method name. For example: @@ -351,7 +351,7 @@ class Session $form->setError($field, $subpassValid['msg']); } // E-Mail address error checking $field = "email"; //Use field name for email - if(!isset($subemail) || strlen($subemail = trim($subemail)) == 0){ + if(!$subemail || strlen($subemail =

问题 Is there a quick and easy way to do such comparison? I've found few image compare questions from stackoverflow but none of those actually proved answer for this question. I have images files in my filesystem and a script that fetches images from urls. I want to check if the image in url is already the same that is on disk. Normally I would load the image in disk and url to a PIL object and use following function I found: def equal(im1, im2): return ImageChops.difference(im1, im2).getbbox() is

问题 How can you diff two pipelines without using temporary files in Bash? Say you have two command pipelines: foo | bar baz | quux And you want to find the diff in their outputs. One solution would obviously be to: foo | bar > /tmp/a baz | quux > /tmp/b diff /tmp/a /tmp/b Is it possible to do so without the use of temporary files in Bash? You can get rid of one temporary file by piping in one of the pipelines to diff: foo | bar > /tmp/a baz | quux | diff /tmp/a - But you can't pipe both pipelines

问题 I'm using msysgit 1.7.7.1 on Windows. I get an error when using git diff . What is causing this? Is there no diff tool included in msysgit? What should I do?
