I'm trying to configure gf to open files under the cursor.
It works always... almost.
I found an issue when the text under the cursor has unfortunately a corresponding directory. In that case, netrw plugin is opened.
Let me give you an example. I am in this code:
[...], MyObject myobject, [...]
I am over MyObject and press gf.
Unfortunately I have in a folder:
myobject <-- a directory
MyObject.java <-- the file to open
netrw is activated.
I tried to check doc to tinker a little bit (suffixesadd, ...), but probably I am missing how to do it properly.
I found this answer, but it is a little bit different in my opinion because in that case the match of the text and the directory were the only 1st one and it was perfect.
Any help?
P.S. what I am trying to do is creating a small vim plugin that could be used to navigate Java projects based on Maven (it's called vim-java-maven).
Just for learning VIM.
As silly as it may sound, Vim considers directories as valid targets so…
:help 'suffixesadd' doesn't help because the directory name is an exact match,
:help 'includeexpr', which is only invoked if there is no match, is not invoked since there is a match.
That behaviour is hardcoded and there is no way to affect it at runtime. The only solution is to write your own Gf() that handles directories more sensibly and map it to gf.

I just switched from Sublime Text to GVIM (on Windows). I am still debating whether I should continue ST or move completely to VIM. One feature that I desperately need (or miss) are
Ctrl+P to go to any file that I want in my list of folders.
Ctrl+Shift+f to find (and replace) any text in those list of folders.
I had added number of folders using Add Folders to Project feature in Sublime Text 3. It was really helpful. Now, I know that CtrlP plugin for VIM can do similar thing, but I can't figure out how to make it search the folders that I want, and not the root directory of current file.
I played around a bit with setting path in my vimrc file without much success.
Can you please help. If it is a repeated question, please excuse me.
Thanks.
AFAIK, ctrlp plugin only searches within one directory (and its descendants). Use the Unix features: make a directory with links to out-of-project directories you are interested in. This way, the association with out-of-project directories is not just something the editor knows about, but something recorded in the actual project.
Search and replace is a bit stickier thing. You want to work with all the files you are interested in, then repeat the replace command through all of them. For example, if you want to do the search for foo and replace with bar on all C files here and under,
:args **/*.c
:argdo %s/foo/bar/g
Ctrl+P to go to any file that I want in my list of folders.
The :find command can be used to "find" a file in the directories specified in the 'path' option:
set path+=/some/arbitrary/path
set path+=/another/one
:find *foo
I find these two mappings very handy:
nnoremap <key> :find * " search in every directory
" in 'path'
nnoremap <key> :find <C-R>=expand('%:p:h').'/**/*'<CR> " start from the directory
" of the current file
Ctrl+Shift+f to find (and replace) any text in those list of folders.
What amadan said above.
Good switch! So you’ve discovered CtrlP. It has extensive documentation built in. Use :h ctrlp to see the full vimdocs explaining the various options. It’ll explain some important settings for working dirs, which are pretty important for a good experience with it. Take for example some of the settings I use:
" The one you really care about...
" Set root to CWD. Another good option is 'r' for VCS mode.
" You should start vim in the root of your project tree
let g:ctrlp_working_path_mode = 0
" You _can_ switch dirs
let g:ctrlp_extensions = ['dir']
" Avoid big/unimportant project areas
set wildignore+=*/node_modules/*,*/build/*,*/components/*,*/_public/*,*/tmp/*,*/vendor/*
" Cache -- get used to pressing F5 on tree changes/additions
let g:ctrlp_use_caching = 1
let g:ctrlp_clear_cache_on_exit = 0
" Somewhat self-explanatory
let g:ctrlp_show_hidden = 1
let g:ctrlp_switch_buffer = 2
let g:ctrlp_max_depth = 6
let g:ctrlp_max_height = 50
" Open *h*orizontally and *j*ump to first win.
let g:ctrlp_open_multiple_files = 'hj'
" Use <C-d> to toggle
"let g:ctrlp_by_filename = 1
For further control of where to look for files outside your working tree, consult g:ctrlp_user_command. There is a Windows example using dir. You’d use that, but with your desired extra paths.
You might also want to add NerdTree, a nice complement to CtrlP. It is reminiscent of ST’s sidebar. Use its ? to get help. It has a menu that lets you quickly add files and dirs, maybe like you’re wanting out of “Add folders to project”.
For search-and-replace, look at ag.vim. I map it to <leader>g (meaning “grep”).
Those mentioned are some of my favorites, but you should explore the world of Vim plugins to decide which others are worth adopting. I recommend trying one at a time while you’re new, rather than a sometimes-opaque “distribution”. Tools to make plugin management easier are Vundle / Pathogen (choose one).
Eureka...!!!!!
After searching tirelessly for days (and sleepless nights), I found my answer (please read on).
First some foolosophy though
I was so keen not to give up on Vim. But this issue was just eating me from inside, and was disruptive in my work flow. I have many project folders in windows that I want vim to search through. Ctrl+p for some reason never really worked. I had some not-so-nice thoughts of giving up on Vim. and then I found this!
My Answer
This is a little different from what I expected. But the answer is Everything (by VoidTools). It allows to search from anywhere and gives results in a fraction of sec. It is by far the best filename search tool in Windows. It supports Regex. (though it is not text search tool). It has a command line interface called
es.exe
using Vim's FindEverything.vim plugin (FindEverything), I was able to search not only through my project folders, but pretty much anywhere. It returns the results in the vim buffer.
Thanks Y'all for your help. I know that not everyone may agree with this solution. But on Windows, this is by far the best solution, I found! Hopefully, it is useful for others why are in same boat!!!
I started using AutoComplPop for automatic code completions. It works great on the single file I am editing, but if file1 is making a reference to a method defined in file2, it doesn't find it.
The docs don't specify if there is a way to make it search a whole project directory, or even just all open buffers, so I can't tell if this is simply not something the plugin does, or if I need to enable something.
I was testing it out on two Ruby files, if that's relevant. Thanks!
Looks like that the cause of the problem is that ACP set the complete option for its purposes to .,w,b,k (see line #125 in autocomplpop/plugin/acp.vim),
call l9#defineVariableDefault('g:acp_completeOption', '.,w,b,k')
while the default value that is used when pressing \<C-n> is .,w,b,u,t,i. And it appears that the very last letter i actually makes the difference: for some reason vim would not use word from an include file opened in a buffer to complete words in another buffer. So, b option is not enough, i must also be included. Adding the following line into my .vimrc helped
let g:acp_completeOption = '.,w,b,u,t,i'
At least it worked for C++ files, but I'm not sure it fixes the problem for the case of Ruby scripts.
Depending on what is on the left of the cursor, ACP (like all the alternatives) decides what completion mechanism to use.
But ACP only uses Vim's default completion mechanisms: if <C-x><C-o> and <C-n>/<C-p> don't provide what you are looking for, ACP won't help. Try them out first.
Oh cool, this plugin looks a lot like neocomplcache but maybe cleaner...looks a little old. Little concerning that there are so many open tickets on that project and no updates in two years.
Anyway, according to the documentation it doesn't...really...say. Very likely its one of the following things:
Your pwd. If the root directory for your source is some/path then that should also be your current working directory. Try typing :cd some/path to see if that makes a difference.
The runtime path rtp. See if adding the directory with your source files to &rtp does the trick.
The path. Same deal as the &rtp setting.
Very likely this plugin is just falling back on the built in ruby omni completion functions bundled with vim. Try help ft-ruby-omni.
I just had the same problem, and I actually found a solution for this.
Apparently you have to set in your .vimrc file the following:
let g:acp_behaviorKeywordCommand = "\<C-x>\<C-i>"
This will make acp look in every file included by your source for completions, as if you were actually typing <C-p>. However, it is slow, after trying it I decided to revert using <C-p> when there are no matches and default behaviour in the other cases.
I am using ":ta " to jump to a method.
For example i got two classes named A.java and B.java. They both have a foo() method and B.java have another method called fooBar(). Then i open A.java and input :ta foo then press TAB then i will got two completion : foo and fooBar. But what i want to jump now is just tag in current file, i don't like tag in other file to display.
And i found tagslist does very good in this job. So if i can use the tag generated by taglist to search from, it will be very nice.
Depending on how many times you call your methods a couple of * may be enough.
Without using tags, gd can be used to go to the local declaration of the method under your cursor. I tend to choose the most low-tech solution usually, so I would go with this one.
But ctags is also able to generate tags for a single file only or for an arbitrary selection of files. It can be done in a few steps but it's definetely not as straightforward as what you are accustomed to do…
Create a file with the name(s) of the file(s) you want to scan. Let's say it's called files.txt and it's located at the root of your working directory.
Generate your tags file using the -L <file> argument: ctags -L files.txt.
At this point you should have a tags file containing only the tags present in the file(s) specified at step 1.
Generating different tags files for the whole project and for single files may be useful, here. A short script generating a tags file named after the current file and making it the sole tags source may make the whole thing easier.
EDIT
Actually, TagList and TagBar don't generate tags files. The output of the ctags <options> command they run is used internally and parsed with all kinds of regexp to filter by scope or filename or whatever.
Unfortunately this cannot be done using ctags. Ctags does not respect context, it is a pure list of all possible "functions". Try to open a tag file with an editor (e.g. vim) and you will see it is just a list of "functions" (in case of Java they are "methods"). Example:
getDesc src/com/redhat/rhn/internal/doclet/Handler.java /^ public String getDesc() {$/;" m class:Handler
getDoc src/com/redhat/rhn/internal/doclet/ApiCall.java /^ public String getDoc() {$/;" m class:ApiCall
Vim just search the file "as is" without giving it any context - it just search for a "function". It is able to search for files, classes, methods, enums etc. Tags format is described in more detail here: http://ctags.sourceforge.net/FORMAT
In Vim you have few possibilities. There are several plugins that gives Vim some context sensitivity, but you cannot use tags for that. Vim itself has a feature called OmniComplete and there are few plugins dedicated for Java. Then you can use Ctrl-X Ctrl-O to start a completition. I recommend you to map this to a different key (maybe Ctrl-Space if you like). More info about Java OmniComplete plugins here:
Vim omnicompletion for Java
Eclim (http://eclim.org/) is very comperhensive, but difficult to setup (you need to run Eclipse in the background). JDE script is easier and also robust (http://www.vim.org/scripts/script.php?script_id=1213). And please note IntelliJ IDEA Community Edition (free) also has a very nice Vim plugin that is free to use. But I understand you - Vim is Vim.
Good luck!
Not exactly an answer to your question, but it seems like there's no way to do exactly what you need, so, i would recommend you the following: for your Java development in Vim, try eclim.
This tool helps you to use your favorite text editor Vim with power of an Eclipse (IDE).
I can't find analogue for tab-completion of :ta, but i know a smart analogue for g] : this is a command :JavaSearchContext. You can map it to something.
For example, if you have two classes A and B, and you have method foo() in each class, then g] will ask you every time you want to jump to foo(), but :JavaSearchContext will always jump to the proper declaration of foo().
Of course, there are many other features.
Say, I have files foo.js and bar.css in my project. There is a ":find" command in vim, which find files, matching string. But this command, alas, has some limitations. For example, if I launch this way - "vim", or even this way - "vim ." - there's nothing to be find in js subdirectory. But if I launch vim this way - "vim js/any_file_other_than_foo.js", then calling ":find foo.js" works pretty well.
Since it is not intuitive (i'm working in the same directory, "pwd" returns the same path), my first question is - can anybody explain how to circumvent this issue? And, even broader, is there any way to type something like find foo - and open first file, which name matches pattern foo.
thanks in advance.
You could try
:e[dit] **/*foo* and then press 'tab' to move to the first match.
the ** is a directory globbing pattern, while * is character matching.
If you were so inclined, you could write a simple fuzzy finder command, for more information you can check out the vim tips wiki: http://vim.wikia.com/wiki/Find_files_in_subdirectories
Vim's :find works by searching each directory in the path variable (and ignores pwd). By default, it does not search recursively. That's why find is only working for you when you open a js file. The '.' in path refers to the directory for the current file -- not pwd.
You can change path to include your desired directories:
set path+=$PROJECT/js
See :help path.
One of the magic bits to use is to add ** to a path to search that path recursively:
" search recursively in my project
set path+=$PROJECT/**
" search recursively from the current file's directory
set path+=./**
See :help file-searching for more magic.
A nice plugin that accomplishes a similar effect is Command-T.
The Command-T plug-in provides an
extremely fast, intuitive mechanism
for opening files with a minimal
number of keystrokes. It's named
"Command-T" because it is inspired by
the "Go to File" window bound to
Command-T in TextMate.
Files are selected by typing
characters that appear in their paths,
and are ordered by an algorithm which
knows that characters that appear in
certain locations (for example,
immediately after a path separator)
should be given more weight.should be given more weight.
Here is a screencast of Command-T in action.
I want to get the file name without the file extension in Vim.
I wrote the following function in my .vimrc file to compile and run the Java program:
:function! JAVA_RUN()
:!javac %^M
:endfunction
map <F3> :execute JAVA_RUN()<CR> :source $HOME/.vimrc<CR>
How can I get the file name without the extension inside the function?
:help expand() should give you the answer, see expand().
You should use the r modifier for %, with %:r instead of % to get the file name without extension.
If you want to write functions to build and execute files, you should also have a look at the documentation for shellescape, in order to prevent problems with spaces in file name or path.
If you want to expand a filename (other than % etc) take a look at fnamemodify()
fnamemodify({fname}, {mods}) *fnamemodify()*
Modify file name {fname} according to {mods}. {mods} is a
string of characters like it is used for file names on the
command line. See |filename-modifiers|.
fnamemodify("main.java", ":r") returns main.
I literally just read a similar question to this (in that someone else seemed to be trying to configure vim to build automagically for them with the F-key), and wrote an answer about how you can leverage the power of vim's :make command without even needing to write a Makefile. In your case, it's less directly related to the question, but I thought I'd mention it in case you were interested.
Furthermore, someone seems to have written something on Vim Tips Wiki about how to set up vim's :make command to specifically work with Java projects built with ant. I haven't worked with Java in a while myself, but in your case specifically it might be a good place to get started.
I came here looking for an answer for a similar question. I wanted to be able to extract the current class name from the java file being edited. I found a very neat way to do this in vim with an abbreviation:
ab xclass <C-R>=expand('%:t:r')<CR>
Place this line in your .vimrc (or similar) for this to work. An abbreviation will auto-trigger as soon as you press space, and so I usually prefix them with 'x' to avoid their accidental expansion.
The trick here is the combination of :t and :r in the argument to expand(). % is the "current file name", :t selects just the tail of the path ("last path component only") and :r selects just the root ("one extension removed"). (quoted parts are from the official expand() documentation.)
So when you are creating a new class in file /a/b/ClassIAmAboutToCreate.java you would type:
public class xclass {
the moment you press space after "xclass", the abbreviation will be expanded to public class ClassIAmAboutToCreate, which is exactly what you need.
Also, note that an abbreviation can be triggered by pressing Ctrl+] which avoids inserting a space after the class name.
