With the normal grep command there is an --exclude option (covered in detail here: Use grep --exclude/--include syntax to not grep through certain files) that lets you ignore specific files when you are grepping.
Ack's --type option takes care of 95% of the cases where you'd want to exclude files, but it doesn't (as far as I can tell) handle the case of excluding a specific file. I've got a compiled JS file that has the contents of every other JS file in it (on a single line), so every time I grep for anything I get back the entire contents of that giant compiled file.
I'd hate to have to give up on ack and go back to grep over this, but it is really annoying. Please, someone tell me there's a way to exclude specific files from ack searches.
To ignore a single file using ack 2.0, provide a filter spec to the --ignore-file flag:
--ignore-file=is:cljout.js
If you run ack --create-ackrc it will output a whole bunch of presets for common files like minified javascript, css and directories like node_modules and .git. Very useful!
Here's the minified js option:
# minified Javascript
--ignore-file=match:/[.-]min[.]js$/
--ignore-file=match:/[.]js[.]min$
And here's how to ignore a directory called foo:
--ignore-directory=is:foo
If you want to save this to .ackrc run
ack --create-ackrc >> ~/.ackrc
and then delete what you don't need from that file.
Also, you can create another .ackrc file in your project's root folder for project specific stuff. I put that in .gitignore so it doesn't clutter the repo.
No, ack 1.x will not let you exclude a single file. In ack 2.0, you can. ack 2.0 was currently in its first alpha is now the current recommended version of ack.
As far as your specific case of the minified Javascript file, what version of ack are you using? ack 1.96 should ignore minified JavaScript based on extension. If the extension check doesn't work, you could probably hack ack itself, since it's a single Perl program. You can hack the is_searchable function.
In ack 2.0, we're looking at ignoring any line over, say, 500 characters because it's clearly not source code.
You may also want to join us on the ack-users mailing list. We're pretty responsive.
Also good to know with ack2.0, you can specify these options in a .ackrc file if you have to frequently filter files.
If you want to exclude specific folder, following command may help you:
ack keywords --ignore-dir folder_name
man ack will provide further details :)
--[no]ignore-dir=DIRNAME, --[no]ignore-directory=DIRNAME
--ignore-file=FILTERTYPE:FILTERARGS

I've written an Extension that, among many other things, renames files based on the Types they contain.
This works fine for files in the directory-tree under the csproj-file -- I find the ProjectItem entry for the file and change its name.
For 'linked'-files (those not in the directory-tree) I can rename the file (via File.Move()) but haven't found a way to programatically modify the csproj-file (after the rename the csproj-file has to be modified manually).
If this is something that can be done I'd appreciate a pointer to the docs showing how to implement the functionality.
The easiest solution for me was to modify the csproj-file.
Open, read whole file, close.
Verify that file I want to rename (e.g. xxx.cs) only occurs in 1 directory
(if it occurs in multiple directories the change has to be done manually.)
Make change
Open, write whole file, close
For an SDK project the change is applied immediately.
For a non-SDK project the change is applied after responding to the prompt that the csproj-file has been modified.
I am using robot framework with RIDE, and for a test I need to find a XML file on my computer and open it to parse the xml and be able to use the datas.
The thing is that I don't know the exact name of the file; the format is numberNameOfTheFile, so it could be 1NameOfTheFile or 25NameOfTheFile.
How can I use regexp in my keyword? Or any other way to achieve this?
Thank you
How would you do it manually - how would you pick the file to use for the verification?
I presume, you are going to look at all the files that are matching a specific name pattern; in Robot Framework you can do that with OperatingSystem's List Files In Directory keyword, which supports passing a name pattern:
${the files}= List Files In Directory /the/path/to/the/dir *NameOfTheFile.xml
Now you have a list object with the filenames that match; if it's empty - there's no such file, which may be a problem (depends on your test/reqs, I don't know). If it has a single member - great, that's your file.
And if there are multiple files - that's another "problem". How would you pick the right file manually? It could be that the newest file is the target one - for that you would go over all of them and find the one through OperatingSystem's Get Modified Tume; or it can be the largest; or the number in its suffix would be the biggest. This really depends on your requirements, and what you are trying to achieve.
"How would you do it manually" is probably the most important question to ask. Think and break down to steps the individual tasks you would do, and now you have the algorithm; see how to put that in code - and presto, the implementation. This applies to scripts, test cases, and business process automation (e.g. software).
I was tempted to mark the question for closing, because precisely this - the algorithm - was missing, only the end goal is stated - while SO is for helping in the implementation part. But, here we are :)
I have several TB of photos, spread throughout subfolders. Each photo has an original, a watermarked resized version, and a thumbnail.
Named as such:
img1001.jpg
img1001_w.jpg
img1001_t.jpg
DSC9876.jpg
DSC9876_w.jpg
DSC9876_t.jpg
etc etc.
What I need to do, is move all of the originals to a different server. Presumably rsync is the best tool for this?
Is it possible to rsync a directory, while excluding any files that end in _t.jpg or _w.jpg? I'm not concerned about possible edge cases where the original file ends with either of those, as there are no such cases in my data.
Or am I better off just rsync'ing the whole lot, and then selectively deleting the _t & _w files from the destination?
Thanks
Yes, rsync is a good choice. Also because it works incremental so you can stop and start it when needed.
By default rsync does not delete anything on remote, I believe.
Yes, you can sync whole directory structures.
It is possible exclude files or folders from syncing.
I think I'm using a command like
rsync -av [--exclude <excludes-file>] <source> <destination>
I have two files where I edited one and left the other just for reference.
However I screwed some codes on the file I'm editing and since its a huge file, I don't know where I made the error or even if it have more errors. It was not altered I just deleted it.
I want to know if there is a program, plugin, script, something that I can insert the two files and override only the parameters of the classes that was edited (the class names wasn't altered).
I know I should have used GIT and all but I didn't. Lesson learned.
Appreciate any help. I'm using SublimeText.
If you're on a Unix-like OS, or you have Cygwyn installed you can use diff and patch to do this.
$ diff -u old.css new.css > changes.diff
$ patch < changes.diff
I frequently search for a token, perhaps a function name, throughout my codebase. My traditional method would be to grep for the term itself. However, the codebase is so large that I can't do this efficiently (it takes minutes).
Is there a way to do this efficiently?
ack (which ignores irrelevent files such as revision control files) is still too slow. ctags only finds declarations, which isn't what I need. I thought something like strigi might work, but I haven't tried it.
I'm on linux, using vim and the GNU toolchain, on a largely C++ codebase.
Use find and fgrep. A decent find will restrict the set to files matching some set of criteria, and fgrep will search within each file. Note that fgrep will be faster than grep.
You could also use an IDE's code indexing features. For example, Eclipse will allow you to go to a function's declaration, and it builds the relevant set in the background while you work. Even vim 7 has some such features, although I don't remember exactly what it does beyond code completion.
