I would like to improve emacs-eclim and add incremental search through java types in the currently edited project (Shift-Ctrl-H in Eclipse).
I can call eclim-java-find variants to get the results in an *eclim: find buffer.
But here comes my question:
How does one implement a behaviour that lets the user to type into a minibuffer (with a prompt) and calls some other function on each minibuffer change (new/deleted character) with the current minibuffer content as an argument or some other way of accessing the current search string.
You can add a function to post-command-hook, for example. which is called after every command (typing a character is also a command: self-insert-command). Your function can then check the minibuffer contents with the function minibuffer-contents.
Just don't forget to remove your function from post-command-hook when your search command is finished. You can use minibuffer-setup-hook and minibuffer-exit-hook to control attaching your function.
Just don't forget to remove your attaching function from minibuffer-setup-hook/minibuffer-exit-hook either when the search command is finished. :)

In vim (in Insert mode, after running exuberant ctags), I am using ctrl-x followed by ctrl-] to bring up a dropdown of various possible words/tokens. It's a great feature.
The problem is that by default, this list starts with a bunch of numeric options and automatically inserts the first numeric option, and if I backspace to get rid of the numbers and start typing a part of a word fresh -- with the idea of searching from the middle of the word -- the autocompletion behavior exits entirely.
I know I could type the first letter of the word that I want, then go from there. But that assumes that I know the first letter of the word, which is not necessarily a given.
For example, if I'm working on a pair-programming project with a friend during a long weekend, I might not remember at any given moment whether he called his method promoteRecordStatus(), updateRecordStatus() or boostRecordStatus(). In this example, I would like to type RecordStatus and get the relevant result, which does not seem to be possible at a glance with the current behavior.
So with that scenario in mind: Is there a simple, vim-native way to tell the editor to start its autocompletion without any assumptions, then search all available tokens for my typed string in all parts of each token?
I will of course consider plugin suggestions helpful, but I would prefer a short, vim-native answer that doesn't require any plugins if possible. Ideally, the configuration could be set using just a line or two.
The built-in completions all require a match at the starting position. In some cases, you could drop separator characters from the 'iskeyword' option (e.g. in Vimscript, drop # to be able to complete individual components from foo#bar#BazFunction()), but this won't work for camelCaseWords at all.
Custom :help complete-functions can implement any completion search, though. To be based on the tags database, it would have to use taglist() as a source, and filter according to the completion base entered before triggering the completion. If you do not anchor this pattern match at the beginning, you have your desired completion.
Is it possible to access VIM's tags-file from Vimscript?
I have a function that searches for what looks like function calls (using a regular expression).
I'd like to confirm that these are really functions by searching the tags file.
Note that I'm looking for function calls and not function declarations.
[This is for navigating long files of Matlab code, by the way]
The taglist() function provides access to the tags Vim knows about from its tags file(s).
Note that tags files by themselves cannot find function calls; but you appear to know that, since you're talking about finding calls yourself and verifying with tags that what you've found actually is a function.
I am using CSCOPE for my project and I have few question.
1) Can I color the search result (mostly when I serach using
":cs f s " i.e. within the open file.
2) Is there a way to search within search? Like I search "ret_val" and it gave 1000 result, instead of going each line, can I search some more like folder name etc?
I am not sure how you use the tool, but generally, the answer is yes.
1) You could either redirect results to file, lets say out.cscope then create syntax file for file type *.csope OR, use a function to run the tool, then locally set up the buffer with adequate hi and match options
2) If you saved search results in a cscope file then you can search it normally. Otherwise you can redir output to new tab/split and again search the buffer (which now doesn't need to have externally associated file. I suggest you to use vim-foldsearch plugin to fold out anything (not) in the match. You can even delete folded sections (with or without any number of context lines) so that only stuff you are interested in finally remains in the buffer (i.e. it behaves like filter). Alternatively you can use unite plugin and it filtering source lines which filters lines as you type the keyword. Actually, I would personally go with that option as it provides most interactive way of working.
I've to replace all occurrences of a specific macro inside some(only some amongst dozens) C functions. Since the file is thousands of lines long, with several instances of the macro in all the functions, I'd like to replace all occurrences within the particular function the cursor is currently placed.
I know VIM provides navigation commands (like [[ to go to the beginning of the current function, and then % to find its matching closing brace) , but I can't figure out how to use them to come up with the required search-replace command.
Can anyone help ?
Place your cursor on the first opening brace. Then type v% and you will see the function body get highlighted. Then type the replacement command :s/find/replace/g and hit enter. This will replace within the selected function.
Note: You will see you command prompt change to: :'<,'>:s/find/replace/g.
Although I would also recommend dogbane's solution, I thought I'd also mention the NrrwRgn plug-in. It's quite useful for working on a continuous subset of a buffer.
I'm trying to write a simple Vim function that takes the name of a file as an argument and reads the contents of that file into the current document (related to this question).
Here's my first stab at it:
fun! Tpl(tplfile)
r c:\tpl\a:tplfile
endfun
That just gives me the following error:
E484: Can't open file c:\tpl\a:tplfile
How do I make the function actually use the value of the tplfile argument?
Replace the line with:
exe 'r c:\tpl\' . a:tplfile
The a:tplfile is a string variable, so to include it in a command, you have to combine the whole lot into one string (with the '.' operator) and then use exe to run the command
:help exe
On a related note (and a shameless plug), if you're trying to add templates (as implied by the post you linked to), my file templates plugin has a command AddTemplate to add a template from your vimfiles/templates directory at the current cursor location. However, the documentation is currently rather poor, so if you decide to use it and have any difficulties, feel free to drop me an email at the address on my website.
