I'm trying to use IntelliJ 10.5's "structural search" feature to find classes that implement an interface, A but do not implement another interface, B.
By searching first for classes that implement A, and then limiting the search scope to 'previous search results,' it's easy to reduce this to just searching for classes that do not implement B, which is conceptually pretty simple. Unfortunately, I haven't yet managed to pull it off.
If I search for
class $clazz$ implements $B$ {}
and then tick 'invert condition' in the text constraints for variable B, it seems to find 'all classes that implement something other than B' even if they also implement B. I've also tried ticking 'invert condition' on the 'complete match' variable, and its effect is not immediately obvious, but definitely not what I'm looking for.
Inicidentaly, someone else asked a similar question on the IntelliJ forums, but got no love. Help me out, stackoverflow!
To find classes that implement InterfaceA, but don't implement InterfaceB, I did the following:
Search > Search Structurally
Click Copy existing template
Select implementors of an interface (within hierarcy) and click OK
Click Edit Variables
Select Interface in the Variables list
Enter InterfaceA in Text / regular expression and click OK
Click Find
Search > Search Structurally
Click Edit Variables
Select Interface in the Variables list
Enter InterfaceB in Text / regular expression, 0 in Minimum Count and 0 in Maximum Count and click OK
Select Previous Search Results in the Scope dropdown
Click Find
Note I had problems when I tried to use the Edit Query button at step 8. I didn't research/retry, but going back to the menu and selecting Search > Search Structurally definitely worked.

I am trying to add a formal parameter in the FORM and PERFORM in an existing code, as I will be need it the extra parameter in a new function that I have to call. The idea is that when executing the new code it keeps showing the error: Different parameter count in FORM and PERFORM (routine: CM_SHOW_CRC, number of formal parameters: 2, number of actual parameters: 3).
The code that I have for the form part is as follows:
FORM cm_show_crc
USING
civ_matnr TYPE matnr
civ_charg TYPE charg_d
civ_werks TYPE werks_d. "The parameter that I added
And the perform code is:
PERFORM cm_show_crc
USING
pis_sdow_alv-matnr
pis_sdow_alv-charg
pis_sdow_alv-werks. "The parameter that I added
The table pis_sdow_alv is type of a structure that also includes the variable WERK(Component type WERKS_D)
Before adding the new parameter WERK the code was working fine.
May anyone know what the problem in this part of the code may be?
There was also another similar question in: Different number of parameters in FORM and PERFORM, however I am not using the syntax CHANGING in my code, as it was also not used prior.
Please do tell me if you need additional information.
Thank you all in advance!
This problem can occur when FORM and PERFORM are in different includes and you only activate one but not the other.
When you activate an include, then it is checked against the active version of all other repository objects it depends on. Not the saved version. This can lead to an annoying catch-22 situation. You can not activate A because it does not match the previous version of B, and you can not activate B because it does not match the previous version of A.
The solution to this conundrum is to activate both objects together. When you activate something in SE80 and you have multiple inactive objects, you get a window where you can select multiple objects to activate together:
In Eclipse, you get a similar list by clicking on the "activate multiple" button:
How would one achieve the same result. I believe the keybinding for macOS Intellij is op+up/down and on windows it is alt+w/d.
Essentially the function highlights the current word, then, with successive presses, expands out to the full string/line/area in-between parenthesis/further out to the next set of parenthesis. Very useful for developing in LISP.
The closest I've gotten is this: https://vi.stackexchange.com/a/19028
Try this plug in: https://github.com/terryma/vim-expand-region
It expands selections based on Vim’s text objects.
Well this may seem comfortable but does not correspondent with the internal logic of vim itself.
See, in vim everything you enter is like a sentence. va{ for example: there is a verb v -> visually select and an object (or movement) { -> paragraph. In this case there is also a modifier a around. You can exchange stuff in this sentence and it will still work vaw, dil, cB and so on. The power of vim is greatly based on that concept.
Of course you can write a function that does vaw first, then S-v and lastly va{ but that will only work with visual selection. It will not work with c or d or anything. So I will recommend to get used to use different keys for different actions.
The visual selection is mostly not needed anyway. Change a paragraph? directly use ca} and so on.
I have found that VI/VA + WOBO (as many times as you need to expand) works similarly. Not as fast but its the same concept and you can even expand/shrink asymmetrically based on your WO's and BO's (Or OW's and OB's depending on how you look at it)
The complete list of keywords that are legal in creating code templates in Netbeans would be accompanied by some documentation, making the "list" a reference. A line from the reference might look like:
${cursor} says to put the cursor at this point in the generated line
Working examples might be included in the reference, such as:
User-defined word to invoke the template: edfold
The template as it would appear in the Netbeans 8.2 RC > Tools > Options > Editor > Code templates tab:
${no-indent}//
// <editor-fold desc="***** ${cursor} *****" >
//
How it works: When I type edfold and hit the Tab key, the template is pasted into my document at the cursor position and looks like the following:
//
// <editor-fold desc="***** # *****" >
//
The cursor is positioned between the 5th and 6th asterisks that follow desc, so that I can then type whatever brief documentation that I wish, if any.
So where is the list of such keywords and their syntax and meaning? Such as:
${cursor}
${selection}
${no-indent}
${arg}
${Type}
and who knows how many more
It just hit me that there are OTHER keywords, two of which I unwittingly used above (I noticed them in someone else's code template and figured out how to use them):
desc
editor-fold
Surely there are other such identifiers to include in the reference.
By the way, the code template above is cute (or not) but is useless without a companion code template:
keypress:
endfold
Code template in editor:
// </editor-fold> ---------------- ${cursor} -------------------
Wherever the first inserted code template is located in your code, the second template must be below it. There is a "collapse" symbol "-" at the left of the first template. Clicking it collapses the code between the two templates. The symbol then changes to "+" and will expand the collapsed code when clicked.
EDIT
I just found this equivalent code template to the edfold and endfold pair just completed. Easier to code, up to a point, and harder to learn to use, but worth it, in the long run. Just highlight text to "hide" by folding, look for the line with the "Light Bulb", click Alt+Enter, and click "Code Folding". (Ctrl+Z to undo!)
But please see my (much better) Answer than this (was a) Question below.
Egg on my face... Googled topic, scanned all hits WAY too fast. In particular, "netbeans 8.2 code templates" pointed to this page involving PHP (think Java), which contained a lot of invaluable info about PHP that applies directly to Code Templates in Netbeans 8.2.
So, that link is part of a manual of sorts for learning how to create Code Templates for Netbeans 8.2 (in particular, and PHP in general).
The reference that I asked for--complete list of keywords (of the form ${ … } )--implies a list of all keywords or reserved words, like ${cursor} and ${selection} that permeate the list of provided Code Templates. But in a sense, that is the list. It is exactly those two Reserved Names. There are no others. Short list.
In the list of provided Netbeans Code Templates, there are a LOT of words that share the same $(...) syntax, but most are placeholder names or parameters that you decide the name and (probably-simple) meaning of.
If a code template contains, for example, class ${className}, the word class is Java code and ${className} is a parameter or placeholder. When the IDE expands the template, class is entered and ${className} turns into class_name, which the IDE automatically selects for editing, suggesting for you to enter the name of the new Java class being defined.
This non-trivial, but understandable, code template and much of what follows it explains much of the process for creating Code Templates. The heading Inserting the code template with code completion ends the explanation, but here is a sort of note of summary from further down:
The syntax of a "code template parameter" is a dollar sign, $, followed by the
parameter's definition between curly brackets {...}. Within this syntax, template
parameters have one of four forms:
* A reserved name that gives processing instructions to IDE (cursor or selection, only)
* An arbitrary placeholder name, such as ${SomeName}
* A descriptive parameter name [that hints at its meaning]
* Pre-defined parameters (??)
Searching for an answer I found ambiguous multi_select filter - AND and OR condition - javascript and looked in the code. I don't see any way to have the multi_select support AND (intersection) and OR (union, the default).
Consider the Tags column in http://yadcf-showcase.appspot.com/DOM_source_select2.html. I would like to see a checkbox, or better a toggle button (not sure the best text, maybe AND and OR as defaults, but even better if the text is configurable) to set behavior.
In this case, assume Tags is multi_select and set to Tag1, Tag2. AND function would show only first two rows. OR function (default) would show all rows except 7 and 10.
I'm not sure this could be achieved with multi_select_custom_func as I'm not sure how to implement the toggle button.
Right now you can use only one AND / OR but not both (with the help of multi_select_custom_func) , but you can open an enhancement request asking for adding checkbox (with configurable label) which will allow you to implement different logic when checked / unchecked inside your multi_select_custom_func implementation
I just wanted to know how you put a cursor in a specific place in a live template for IntelliJ
For example:
# $var$ is an insance of the $objectType$ class
assert isinstance($var$, $objectType$)$END$
What happens here is that your cursor gets dragged to $var$ in the comment string first and then to your other values inside assert. What I wanted to know is how you chose where the cursor goes first.
I've read the documentation, but this is not mentioned, although a lot of other things are.
You can arrange the order that your variables are visited in. You find the information under bullet number five in this IntelliJ help document: http://www.jetbrains.com/idea/webhelp/creating-and-editing-template-variables.html
To arrange variables in the order you want IntelliJ IDEA to switch between associated input fields, use the Move Up and Move Down buttons.
Edit
You have to update the macro definition to similar to this:
# $varComment$ is an insance of the $objectTypeComment$ class
assert isinstance($var$, $objectType$)$END$
And then you define the order and expression to something like this (I didn't have any good expression for the var and orderType for you):
Since you fill in the Skip if defined for the two comment variable they will just take the values from the var and orderType and fill it in. This will do exactly what you are looking for :-)
