Can ctags tag symbols from a directory up in the hierarchy also or is it limited to create tags for current and sub-directories only?
Basically I'm looking for Visual Studio like symbol cross referencing it is very helpful in understanding alien source code flow.
If not Vim, then which other editor should I use?
thanks
Ctags only recurses to subdirectories. But all you have to do is run ctags -R . in your project home directory, and it will create a tags file for your whole project.
You aren't limited to specifying one tags file in Vim. This is an alternative to the other answers; you can just do something like:
set tags=tags,~/wintags,c:/path/to/moretags/etc
So you don't need to take the time regenerating a monolithic tags file when you just want to update your local tags.
Regarding the OP's comment in another answer,
yes thats correct but when i open a file say proj/dir1/def.c and press ctrl+] on a function name which is defined say in proj/dir2/abc.c, I get tag not found :(
You could also create one tags file for all of your projects at the 'proj' root:
set tags=tags;c:/path/to/proj
This will use the first file named tags that it finds as it walks up the directory hierarchy from where you are.
You can combine these two techniques to have a project-local tags file and then a "global" tags file that isn't updated as often.
Whilst it's got similar user interface for asking it to do it's thing, so you need to actually specify "go down directories", I find that cscope is a very nice tool, whcih does everything that ctags does and a bit more.
ctags (well, exctags at least) can create tags for as many directory trees you want. Simply run
exctags -R dir1 dir2 ...
Then vim knows about all the symbols you need. For example, one of the directories could be /usr/include in addition to your own source directory.
Make sure to run vim path/to/file.c from the same directory you created the tags file in.

I'm looking for something that's a bit robust in how it finds files in Emacs. I have a project made up a number of different files, and a lot of them. So, I think maybe Emacs would need to cache a lookup or something like that to make a quick find/open facility to work. It would need to also be configured per project to consider only some directories and exclude others inside of this project, since a number of files and directories are generated and hold a massive amount of text and sometimes a concatenated representation of the rest of the code.
Is there a quick file open/find like IntelliJ's find file, or Sublime's? Something with fuzzy search. But in Emacs? That could help with this problem?
Projectile can probably do what you're after. It describes itself as a "project interaction library" with facilities for finding project files quickly.
Try projectile: https://github.com/bbatsov/projectile (see its fancy UI, helm-projectile). You'll have the command projectile-find-file. It is based on projects (they are defined by a .git/.gh/… or a .projectile).
permanent caching ? Yes
filter out directories ? Yes (with a command or a config into the .projectile)
fuzzy search ? Yes, a few: emacs'default, ido, ido-fuzzy, grizzl or helm.
you install it simply with M-x package-install RET projectile RET.
See this EmacsWiki page, which is is a jumping-off place for multiple answers to your question.
Emacs has a built-in file-name cache -- see (emacs) File Name Cache and this page.
See also Emacs bookmarks, and in particular, Bookmark+. You can bookmark any file or set of files. You can bookmark a Dired buffer, including its omit set, markings, and included subdirs. You can bookmark a set of such Dired buffers. You can aggregate bookmarks and use them to perform actions that set up environments etc. They can be triggered in various ways. You can bookmark Emacs desktops. You can tag bookmarks and files & dirs with free-form tags, which lets you organize them flexibly into overlapping sets.

I was using ctags with C on an old project, mostly coding in Vim. ctags was working fine[redirecting perfectly]
Now the code base has changed a lot, I ran command :
ctags -R, now when I do Ctrl + ], I am not taken to the function/macro definition as earlier it used to do, at times it takes me to the correct line but mostly it takes me to some lines above/below the actual definition. Can anybody please help?
It sounds like you have a tag file for each directory in your project. ctags -R only changes the tag file in the current directory It does not change all the tags files recursively. This is why when you do <C+]> you jump to a place sort of near the actual definition.
To fix this you should only have one tags file and it should be located at the root of you project. Then in your vimrc add set tags=./tags;/. This allows vim to search for a tags file starting from you current directory up the tree until it finds one. (stopping at the root directory)
I have troubles with replacing file contents in my current project. I renamed a directory, and a lot of class names has been changed cause of this. A want to rename this classes with netbeans, but I cannot setup the file path pattern well.
The previous directory path was: Test/TestCase under Source Files, and the new path is Test/UnitTest. So I have to rename the TestCase word to UnitTest in my php files.
I tried with *.php, it works (of course it works...), but returns every php file in the project which contains that word, and I don't want to choose from circa half thousand files the right ones. The files of the unit test system could easily contain the TestCase word...
Tried out the following patterns, but they gave empty result:
Test\UnitTest\*.php
*Test\UnitTest\*.php
Test/UnitTest/*.php
*Test/UnitTest/*.php
Test/UnitTest/*
I have not a clue what I do wrong... I tried to search a tutorial for file search patterns but have found only regex patterns and those are definitely not what I was looking for. Can anybody help me?
Lol, I checked it again, and I realized, that I didn't notice the "scope" part last time. In that you can choose the current selection instead of the entire project. So the pattern matches only the file name, not the relative path of the file...
It was so obvious... This is an epic fail, I think I was too tired...
I am trying to use a MEL script to load ANIMATION.MA file that references CHARACTER_RIG.MA. The CHARACTER_RIG.MA and ANIMATION.MA files are produced by someone else and supplied to me. The ANIMATION.MA is looking for N:/Project/Maya//char/character/CHARACTER_RIG.MA
If I open ANIMATION.MA from Maya, or use the equivalent MEL command I always get prompted with:
"Reference File Not Found"
Reference File Not Found: N:/Project/Maya//char/character/CHARACTER_RIG.MA.
[Abort File Read] [Skip] [Browse...] [Retry]
If I tap browse, and select the CHARACTER_RIG.MA then it opens perfectly. I can see it created a reference in the Reference Editor that has the Unresolved Path (N:/...) , the Resolved Path (/my/path) and the namespace and the namespaceRN.
My question is, how do I do the equivalent of the "Browse..." from MEL? I tried pre-creating a reference, but it doesn't let me set the unresolved path, so when I load the ANIMATION.MA it keeps prompting in MAYA.
file -f -options "v=0" -typ "mayaAscii" -o "/Source/project/assets/anims/ANIMATION.MA"
If you know the directory where the file is, then you can use the dirmap command. The command dirmap allows you to remap directory structures if your disk configuration changes. So in this case it would look like:
dirmap -en true;
dirmap -m "N:/Project/Maya//char/character" "/my/path";
Possibly more manageable if you have lots of mappings to do especially when moving form a windows machine to a *nix one. However it is much more useful to define your project structure because then things just work when you move, tough this may not be the best of choice for shared assets.
I ended up finding several solutions:
Rename the RIG.MA file to match the filename in ANIM.MA (they were different in my case) and put it in one of the search or project folders that MAYA uses and it will automatically find it.
or
Programatically through code (or manually) edit the ANIM.MA file to remap the file/folder of the RIG.MA to where you want to load it from. Note: You
also need to remap any other files, such as textures. I did this with
perl -pi -e 's/\Qold-path\E/\Qnew-path\E/g' ANIMATION.MA
HTH someone else.
Quick and easy, File, Project, Set and select the folder where meshes or whatever it is.
Basically my question is the topic ^
I have 4 files that are massive. I need to put them in resources under my maven project structure. Whenever I do a string-based refactoring or search/replace... I basically want the IDE to ignore these files altogether.
Yes, I know I can exclude them and do the replacements manually... but like I said, I want to remove any possibility that they can be modified through the IDE (without having to write-protect them I guess, or revert them all the time if the version control says they've been modified).
Is there any way I can exclude these files?
There are two questions there:
1) How to exclude these files in string based refactoring such as search and replace
You can set up a custom scope when you do a find and replace. This custom scope is saved so you don't have to set it up every time you do a find and replace.
Open the find-and-replace window or the find-in-path window and you will see the scope section in the window with "Custom" as the last option. You can select the files that you want to include/exclude here.
2) How to prevent files from being modified in the IDE without write protecting them
This I'm not sure about. You can add them to a separate change list so that they will always be grouped away from your main set of changes or add them to the vc ignore list. But this doesn't stop the IDE from modifying them. Perhaps you should find out what is editing those files and stop that process?
You can mark the directory as Excluded in "Project Structure->Modules"
You can mark this directory as for "Generated Sources Root"
