I'm not sure where the documentation is.
meowface
Yeah, I struggled with that as well. The landing page of any software project like this should at the least have a lot of example syntax with output, plus a glaringly obvious link to full documentation.

It's following the illustrious Haskell tradition of barely-documented code.

(Non-snarky follow-up: Haskell code is often woefully under-documented, for whatever reason. Possibly because people think that the type signatures are sufficient, or possibly because Haskell code lends itself to concision and documentation runs counter to that, or possibly because Haskell projects are often the result of one person's work, diminishing the need to explain oneself. In any case, it's an unfortunate fact of many Haskell apps and libraries.)

This looks like a cool idea. I think a couple of (neat!) examples, stuff you can't easily do with normal grep, will go a very long way. The list of features is secondary in my opinion.

Taking this idea further, you could perhaps also have examples of use for each language.

You basically had this with the Smalltalk refactoring Browser, where each search popped up displayed in a browser window. Then you could easily AND such searches together by executing a script in the browser window. Slightly more sophisticated combinations were possible with just a few lines of scripting.

On top of that, everything above applied to syntax-driven rewrites and refactorings.

a binary for os x would be nice, since installing cabal/ghc currently is a bit of a pain

Examples or it didn't happen.

e.g. $ cgrep -r --header "stdio.h" to search recursively for headers

$cgrep -r --identifier VARname to search for a variable

etc..

Darn, no SQL support. I often find myself wishing something like this existed for SQL, so I could, say, find all places where field X in table Y is updated, or referenced in a WHERE clause predicate, etc.

interesting request; I've wanted something like this before but never enough to really look for it.

I'm surprised there isn't a tool that can do this already.. perhaps under the guise of refactoring?

How do I build this for Windows? I think I have something Haskell related installed because I see lambda as an icon on the .hs files.

blah.c:

  void foo(item *x)
  {
      x->blah(1, 2, 3);
      x->blah (4, 5,
            6);
      blah (7, 5, 1);
      foo (4, 5, 6);
      x->blah (4,
            5, 6);
  }
  
  
  void foo2(item y, item *x)
  {
      y.blah(1, 2, 3);
      y.blah (4, 5,
            6);
      blah (7, 5, 1);
      foo (4, 5, 6);
      x->blah (4,
            5, 6);
  }
search in blah.c for a call to blah() with 5 as 2nd argument from any structure or pointer.

  cgrep --code --semantic '_1 . OR -> blah ( _2 , 5, _3 )' blah.c
output:

  blah.c:6:    x->blah (4, 5,
  blah.c:7:          6);
  blah.c:10:    x->blah (4,
  blah.c:11:          5, 6);
  blah.c:18:    y.blah (4, 5,
  blah.c:19:          6);
  blah.c:22:    x->blah (4,
  blah.c:23:          5, 6);

Any examples or reasons why I should use this over the_silver_searcher?

It really sucks that 15 languages that people use less than C# are supported before anyone thinks of adding support for C#.

Why does everyone hate Microsoft's languages and love Apples?

TallGuyShort
The most reasonable explanation is that this is developed by (an) Apple user(s) and adding support for Apple's languages is simply easier and more valuable than adding languages for a platform they don't use. If it's worth it to you or other C# users, I'm sure they wouldn't mind you submitting a pull request.
WorldWideWayne
They actually do support C#, but I missed it because I read the list too quickly.
djeikyb
I've not tried it, but the linked article claims c# is supported. Quote:

    Languages support for Awk, C, Cpp, Chapel, Csharp, Css,
WorldWideWayne
You know - I totally missed it because of the way it was written. Sorry for complaining! Thanks so much :)
egonschiele
I've thought about something like this before, and I'm really excited to see how fully-featured it is. Written in Haskell is also a big plus.
mcrider
Would love a UI for this and an editor -- I still use TextWrangler/BBEdit daily to grep large chunks of source code and then edit in place (e.g. for refactoring). Just getting the search results requires opening up each file individually then editing, which is just too slow.
edderly
I was curious, but had no idea how to use this on Ubuntu

sudo apt-get install haskell-platform

download and extract the tarball

cd awgn-cgrep-8af1beb

cabal cgrep.cabal

Unfortunately what stops me using it on a large codebase is that I can't exclude directories like .repo (not sure about .git).

volune
How does this compare with Ack?
kumarishan
can it be integrated with sublime text ?
michaelmior
JSON output is incredibly useful in combination with jq[1] for processing the output. Some things become much easier than with standard *nix tools IMO.
