I'm optimizing my code at the moment (android game), and wanted to replace all foreach(for(:)) with normal fors. Is there a way to find them all? Ctrl-F only looks through the current file and Ctrl-H doesn't seem to find any java constructs (not sure if right word: ifs, whiles, accessors etc.). Preferably without a plugin, but any answer accepted. It would also be nice if there would be a possibility to search for any string (* in Search).
TL;DR: Looking for way to find all foreaches in eclipse.
First of all, I must say, this sounds like a really strange optimization. Keep in mind that if you have, say, a LinkedList you would be far worse of going through a
for (int i = 0; i < list.size(); i++) {
element = list.get(i);
...
loop, than using an iterator (which for-each loops does). Smells micro-optimizations long way to me.
That said, here's a solution for you:
Make sure the root source folder is selected
Click Search / File Search
Mark Scope as "Selected resources"
Mark Regular expression
Search for a regular expression such as for\s*\(.*:
The expression matches strings on the form for, followed by some white whitespace, followed by ( followed by some characters, followed by : (which kind of characterizes a Java for-each loop).
Right-Click on the project, choose search and you're able to replace all for-commands with a regular expression like for(.*;.*;.*) with other expressions you want to.

I'm using mainly Notepad++ for my C++ developing and recently i'm in need for some kind of basic autocompletion, nothing fuzzy, just want to type some letters and get my function declaration instead of having a manual opened all of the time..
The integrated autocompletion feature of my Notepad++ version (6.9.2) gives the declaration of basic C functionality like say fopen and parses my current file user defined functions, but without declaration.
I guess it's normal for a text editor to not give easily such information since it has nothing to parse i.e. other files where your declarations are (as it's not an IDE), but i don't want either to mess again with MSVC just for the sake of autocomplete.
Is there an easy, not so-hackish way to add some basic C++ and/or user defined autocomplete?
UPDATE
Adding declarations the "hard way" in some file cpp.xml is a no-no for me as i have a pretty big base of ever changing declarations. Is there a way to just input say some list of h/cpp files and get declarations? or this falls into custom plugin area ?
Edit the cpp.xml file and add all the keywords and function descriptions you'd like. Just make sure you add them in alphabetical order or they will not show up.
Another option is to select Function and word completion in the Auto-Completion area of the Settings-->Preferences dialog. NPP will suggest every "word" in the current file that starts with the first N letters you type (you choose a value for N in the Auto-Completion controls).
I'm making a custom .tmLanguage file to highlight the syntax I'm using correctly and generally make coding with it easier. I'm almost done, and I got the autocompletion working using a .sublime-completions file.
There's just one minor flaw I'd like to change. I have a pretty long list of functions, and almost all of them contain an abbreviation of the word 'parameter', PAR. When I start typing that word, the following are all in the list of completions:
PAR command
DEFPAR command
JDATA command (because the description contains PAR)
SPAA command (because there's a P in the command and an A and an R in the description)
What I want is only for the commands that begin with PAR to show up, so from the list above, only the first item.
So, like this:
In other words, I want the completions to show up based on the literal string I'm typing, and only from the trigger part of my completions file, before the \t only.
That completions file looks like this:
Highlighted in orange is what I want my completions list to be based on.
I hope this is understandable. Any help is greatly appreciated.
This is not possible. By design Sublime's autocomplete feature uses fuzzy matching, so if there are a number of options that all contain the same pattern, but you don't quite remember which one you want, you can type the pattern and have all of the options available. The more you type, the smaller the list of possible options becomes. This is a good thing®, otherwise you'd have to remember the exact command you're looking for, which kind of defeats the purpose of autocomplete and code hinting.
There are some pretty basic tasks and I'm in doubt how it can be effectively done in Eclipse IDE:
Content assisted variable declaration/assignment:
Imagine you have to write something like this DateFormat df = new SimpleDateFormat();. How can it be effectively typed? One guess like DateFormat df = new plus some quick Ctrl+Space, not very, very long SimpleDateFormat. But this does not work, it will show completely useless alphabetically sorted types from classpath, usually unassignable to DateFormat.
Extracting variable:
Is there any way to extract variable like Alt+Shift+L does but WITHOUT the need to manipulate the mouse to select expression or whole line? Just like extract content under cursor? Or is there some way to select line (this work only for standalone expression but better than mouse)?
Extracting field:
Any way to extract field in more convenient way than perform 2. followed by another magic - convert variable to field?
I'm doing mentioned combos every 1-5 minute, and it seems to me like editor completely unusable for serious work. (Iff one is not Ray Manzarek)How are you typing in Eclipse? Note that I prefer default settings, no fine-tuning which stops working after first upgrade or terminal change. Thanks.
For your first problem, here's how I do:
DateF<ctrl-space><Enter> df = new SDF<ctrl-space><Enter>
For your second problem, I simply select the text I want with ctrl-shift-left_or_right_arrow.
For your third problem, no idea. I don't remember having transformed a local variable into a field for a long long time. Maybe I just know beforehand which fields I'll need for a given class.
For the first one, I find I just need to type DateF Alt-\ Enter df = new Sim Alt-\ Enter ;, which doesn't seem too bad to me.
For your second question Shift-Option-Right extends the selection to the right one word at a time, and Shift-Option-Left to the left; that, in combination with the keyboard shortcut you mention, should do what you want (those are Mac keys, of course, but I'm sure there are Windows equivalents; I understand some folks actually develop software on Windows.)
For number three: don't think so. You could write your own plugin to do it pretty easily.
TL;DR I want to use Xcodes finder with regular expressions to update outdated function calls.
Example 'numFrames:??? endFrame:#"step1*_0??? text=" "' where the question marks are replaced by a 1-3 digit number and * is a letter and just delete all of that.
Long Version First off I know I need to refresh my memory on regular expressions but I feel like I'm banging my head into a wall on this...
I want to use finder to update my calls to a function. I was playing ~400 image sequences in my application and it was impractical to keep updating the individual sequence lengths when they would get updated. Now to solve that I have my application figuring out the length on its own, but I still have outdated length declarations. I could go through one at a time and delete them out but I know Finder can use regular expressions...
What I want to delete out is 'numFrames:??? endFrame:#"step1*_0??? text=" "' where the question marks are replaced by a 1-3 digit number and * is a letter.
If you could point me to a good xcode and regular expression guide (Teach a man to fish...) or just tell me how to do this, either would be great.
In the find control click the magnifying glass and choose "Show Find Options". Change the Style option from "Textual" to "Regular Expression". Type your regular expression into the search box.
My NetBeans dictionary is kind of... illiterate? It's flagging words like "website" and the "doesn" part of doesn't. I right-clicked expecting to see your standard Add to dictionary... option but found none. I browsed the menus and also found nothing.
How do I educate my NetBeans spellchecker?
It looks like the spell checker is a relatively recent addition. There are basic instructions on how to change the dictionary here.
Adding an unknown word to the dictionary requires alt + enter while the cursor is on the 'misspelled' word. This might take care of the most glaring omissions.
If it highlights just 'doesn', then it probably isn't aware of English-style contractions (i.e., it doesn't know that words can span across an apostrophe). Until that is fixed, I would recommend just adding 'doesn' as a separate word using the above method.
