diff

问题 I produced a diff.txt file with the command (executed from ~): diff -r /full/path/to/directory/A /full/path/to/directory/B > diff.txt The generated diff file looks good. Now I run (always from ~) patch -p0 <diff.txt or I also tried: patch <diff.txt I would expect it to apply the changes to the files in /full/path/to/directory/A so that after the operation they will be identical to those in /full/path/to/directory/B But it only says: * Only garbage was found in the patch input. What am I

问题 Can somebody recommend some papers (literature) or code snippets about tree-based diff algorithms for XML (based on the DOM-tree) Thank you very much. 回答1: Here is one useful paper on the same : http://pdf.aminer.org/000/301/327/x_diff_an_effective_change_detection_algorithm_for_xml_documents.pdf Here is one tool you can experiment with: http://www.cs.hut.fi/~ctl/3dm/ You may find the Java source for the above tool as well which maybe of great use. 来源： https://stackoverflow.com/questions

问题 This question already has answers here : diff a ruby string or array (12 answers) Closed 5 years ago . I've looked at diff-lcs ( http://raa.ruby-lang.org/project/diff-lcs ) but it's poorly documented, and appears to be unmaintained. Are there any good, actively maintained ruby gems for diffing text or html files? 回答1: I looked around and couldn't find an existing gem or library that offered a convenient way to generate diff style output from ruby. I just released diffy which does what I want.

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 5 months ago . Github is a truly amazing service. I'm keen to understand what their architecture is like and how they fit the different pieces together; how they store the repositories, how they access those repositories to show file contents, how they handle displaying diffs, etc. Could

问题 I have two files A1 and A2 (unsorted). A1 is previous version of A2 and some lines have been added to A2. How can I get the new lines that are added to A2? Note: I just want the new lines added and dont want the lines which were in A1 but deleted in A2. When i do diff A1 A2 , I get the additions as well as deletions but I want only additions. Please suggest a way to do this. 回答1: diff and then grep for the edit type you want. diff -u A1 A2 | grep -E "^\+" 回答2: All of the below is copied

问题 I am going to be periodically pushing a set of text-based data from a web-page to a server , probably as JSON. For every push, none, some or all of the data may have changed. To reduce the amount of data I have to send over the wire I would want to only send a diff of the changes in each push. Do you know of any pre-made solutions / tools / libraries that: Dynamically build a diff of JSON as changes are made to it (to avoid storing oldJson and newJson and doing a full diff every push) written

问题 How can I plot the results of a unix diff command side-to-side instead of one difference after the other? See below for an example: diff /tmp/test1 /tmp/test2 1,4c1,2 < asfdsadf < asdfsad < fsaf < fdsadf --- > asdfsafdsf > saf 6,8d3 < sadf < asdf < sadf 10d4 < fasd 12,13c6,14 < sadfa < fd --- > sadf > sadf > sadf > sadf > sadf > sadf > sadf > sadf > safa I would like to have something like: diff /tmp/test1 /tmp/test2 1,4c1,2 < asfdsadf > asdfsafdsf < asdfsad > saf < fsaf < fdsadf --- 6,8d3 <

问题 Closed. This question is off-topic. It is not currently accepting answers. Closed last year . Locked . This question and its answers are locked because the question is off-topic but has historical significance. It is not currently accepting new answers or interactions. I'm trying to find the files existing in one directory but not in the other, I tried to use this command: diff -q dir1 dir2 The problem with the above command that it finds both the files in dir1 but not in dir2 as well as the

问题 I think this should be simple but what I've seen are techniques that involve iterating over a dataframe date fields to determine the diff between two dates. And I'm having trouble with it. I'm familiar with MSSQL DATEDIFF so I thought Pandas datetime would have something similar. I perhaps it does but I'm missing it. Is there a Pandonic way of determing the number of months as an integer between two dates (datetime) without the need to iterate? Keeping in mind that there potentially are
