is the clearcase path syntax is universal one. my_source.c@@\main\10.1_bugfix\another_branch\0 is this path is standard one? I invoked the following in emacs and it is working. how does emacs diff understand this path. somehow clearcase informs operating system how to interpret that path. or emacs-diff know of this path syntax? $ diff my_source.c@@\main\10.1_bugfix\another_branch\0 my_source.c VonC This is an extended path . It is working with dynamic views , which give access to the branches and versions of an element. See " Base ClearCase path meaning ". In your case, you access the version

This turned out to be more difficult than I thought. Basically, each day a snapshot of a customer master list is being dumped by a system into CSV. It contains about 120000 records and 60 fields. About 25mb. Anyway, I'd like to report on values that change between one snapshot and another. It isn't a plan file diff, as it must be matched on the leftmost column value which contains the customer's unique number. Lines could be inserted/removed etc. All fields are strings, including the reference number. I've written a solution with LINQ but it dies with larger datasets. For 10000 records, it

If I have a sample data frame like mtcars, and I want to find the difference between mtcars$qsec for all rows, I can do diff(mtcars$qsec). But is there a simple way to make diff(mtcars$qsec) a new column in the original mtcars data frame? I'm finding it difficult because there's one less row in diff(mtcars$qsec) than the rest of mtcars. > head(mtcars,3) mpg cyl disp hp drat wt qsec vs am gear carb Mazda RX4 21.0 6 160.0 110 3.90 2.620 16.46 0 1 4 4 Mazda RX4 Wag 21.0 6 160.0 110 3.90 2.875 17.02 0 1 4 4 Datsun 710 22.8 4 108.0 93 3.85 2.320 18.61 1 1 4 1 G.

This question already has an answer here: xml diff in ruby? [closed] 9 answers What's the easiest way to see the difference between two xml files using? I looked into Hpricot and Nokogiri but couldn't find any good comparison methods. I've also looked into unix tools like diffxml , but would rather use something in ruby. Anybody got any ideas? What about diff.rb ? You export your two xml documents to arrays and get the diff with that library. Try the equivalent-xml gem . It can tell you if two XML documents are semantically equivalent I found that was easier to use the Java library XMLUnit

What is the best way to do this for PHP? Is there any PHP function that can do this, considering the column content could be very large? If PHP function is not available, what shell utility can I call? thanks there aren't any built in diff functions in PHP. but, hooray for PEAR: Text_Diff (never used it tough, but in PEAR i trust). and there's even a PECL package, xdiff hint: pear classes are pure php, pecl packages are modules. normally, modules are faster than classes, but it also depends on the functionality. you just have to test and evaluate. for storing: i'd store the plain text, not the

I need to release some software quite frequently, and the software is contained as a VMWare disk file, i.e., .vmdk file. What I want is some kind of binary diff and patch utility to make the delta generated as small as possible. David Cary Let me start off with tried-and-true approaches, then point out some more recent approaches. approaches that I have seen work with binary files A long time ago, people expanded the old and the new versions of a binary file into temporary "text" files (every byte expanded to 3 bytes: 2 hex digits and a newline). Then run these two "text" files through an old

Are there any libraries out there for Java that will accept two strings, and return a string with formatted output as per the *nix diff command? e.g. feed in test 1,2,3,4 test 5,6,7,8 test 9,10,11,12 test 13,14,15,16 and test 1,2,3,4 test 5,6,7,8 test 9,10,11,12,13 test 13,14,15,16 as input, and it would give you test 1,2,3,4 test 1,2,3,4 test 5,6,7,8 test 5,6,7,8 test 9,10,11,12 | test 9,10,11,12,13 test 13,14,15,16 test 13,14,15,16 Exactly the same as if I had passed the files to diff -y expected actual I found this question , and it gives some good advice on general libraries for giving you
