I have Form Editor and on every double click event on editor input I need to avoid duplicate instance of the form editor to open. I'm setting the editor name by setPartName
I need to check that name and to be open only one instance
You can specify a matchingStrategy class in your org.eclipse.ui.editors definition of the editor which lets you control which editor is used to open files,
For example this is the definition of the PDE plugin.xml/MANIFEST.MF/build.properties editor:
<extension
point="org.eclipse.ui.editors">
<editor
default="true"
name="%editors.pluginManifest.name"
icon="$nl$/icons/obj16/plugin_mf_obj.png"
class="org.eclipse.pde.internal.ui.editor.plugin.ManifestEditor"
contributorClass="org.eclipse.pde.internal.ui.editor.plugin.ManifestEditorContributor"
matchingStrategy="org.eclipse.pde.internal.ui.editor.plugin.ManifestEditorMatchingStrategy"
id="org.eclipse.pde.ui.manifestEditor">
<contentTypeBinding contentTypeId="org.eclipse.pde.pluginManifest"/>
<contentTypeBinding contentTypeId="org.eclipse.pde.fragmentManifest"/>
<contentTypeBinding contentTypeId="org.eclipse.pde.bundleManifest"/>
</editor>
The matchingStrategyclass must implementIEditorMatchingStrategy` which has one method:
public boolean matches(IEditorReference editorRef, IEditorInput input)
Returns whether the editor represented by the given editor reference
matches the given editor input.
Implementations should inspect the given editor input first, and try
to reject it early before calling IEditorReference.getEditorInput(),
since that method may be expensive.

Is there any shortcut/setting/plugin available in intellij where I can create test data structure with some default values ?
e.g.
Map<String,String> stringMap = new HashMap();
stringMap.put("1","A")
stringMap.put("2","B")
stringMap.put("3","C")
I dont want to type all of the above as I want to test very quick with any values.
You can use the 'Live Templates' functionality, for instance. A guide on how to create such a template can be found here.
Use live templates to insert common constructs into your code, such as
loops, conditions, various declarations, or print statements.
To expand a code snippet, type the corresponding template abbreviation
and press Tab
In the screenshot below, I created a custom template called smap in the 'other' template group, added your code to it and selected the language (Java) that this template can be applied to.
Once in the editor, I can type smap and a pop-up will appear suggesting me to use the existing template to replace the abbreviation with code. Hitting Tab or Enter will perform the replacement.
I want to change the header name of the ABAP program. What can I do or where can I find the option to edit the header?
Two ways for this:
Set it in program options. Select the program and check menu Goto / Attributes.
Or you can create a GUI title and set it via ABAP. This overwrites attributes' setting.
More about how to achieve: here.
To change the program header is more easier than it seems.
Just open you program via SE38 -> Goto -> Properties -> Check the title field and change -> Save
And you are done. :)
I have this.
Usually is changing the name in atributes with transaction se38, but sometimes this don't work, you need in the transaction se80, create a title GUI, if yuou don't have a title created, righ clic in the program name, create -> GUI title.
And put your name and code.
and in your program (se38) in PBO, you have to call the title with
SET TITLEBAR '100' (Put your title code)
(100 is the title code), but this instruction have to need inside of a moodle, if is outside don't will work.
I use the first moodle that i have in my PBO (i don't know if is the best decition or the right form, but is a way and works).
finally the title change
The path is SE38 -> (Put Program Name) -> Now open the program in edit mode -> Select the option GOTO -> select Properties Change the program title.
I am using InteliJ and really love using it. One of the questions I have is this:
Is there a way to create code short cuts?
For instance, while bug testing, I am forever writing:
<?php die(var_dump($var)); ?>
and figured it would be great to have a shortcut key to automate this. i.e.
"Cmd Option D"
or something similar to dump the pre-defined statement into my code...
Any thoughts on this?
You can use Live Templates:
To define a template go to Settings/Live templates, then select group or create new group of templates and hit the green plus button and select Live Template.
In the abbreviation field type for example vd which will be the trigger for your snippet, define context, which represents the languages this template will be available for and put this in the Template Text field:
<?php die(var_dump($SELECTION$)); ?>
The $SELECTION$ part is a variable which represents current selection.
Now when you are in editor, you can just type vd and hit Tab. That will expand your snippet and put your cursor inside var_dump().
You can event type the variable name you want to dump, select it, hit CTRL+ALT+T, which will show you a Surround with dialog, where you can choose your template. After you select it your variable name will be surrounded with the var_dump snippet.
Another way to invoke a live template is to hit CTRL+J which will show you autocomplete popup with the available templates.
All is in the title.
If a have opened the three files:
/some/relatively/long/path/dir1/file_a
/some/relatively/long/path/dir1/file_b
/some/relatively/long/path/dir2/file_a
The file dropdown contains:
file_a (/some/relatively/long/path/dir1)
file_a (/some/relatively/long/path/dir2)
file_b (/some/relatively/long/path/dir1)
And that bother me because I have to look on the right to differentiate the two file_a, and on the left for the others. This happens a lot to me mostly because I code in python, and thus I often have several __init__.py files opened.
How do I get jedit to display
/some/relatively/long/path/dir1/file_a
/some/relatively/long/path/dir1/file_b
/some/relatively/long/path/dir2/file_a
config:
jedit 5.1.0
java 1.6.0_26
mac osx 10.6
Unfortunately this is not easily possible currently, I just had a look at the source and this is not configurable.
You can:
Submit a Feature Request to make this configurable (good idea in any case)
Create or let create a startup macro that
registers an EBComponent with the EditBus that listens for new EditPanes getting created
retrieve the BufferSwitcher from the EditPane
retrieve the ListCellRenderer from the BufferSwitcher
set a new ListCellRenderer to the BufferSwitcher that first calls the retrieved ListCellRenderer and then additionally sets the text to value.getPath()
Try the Buffer List plugin as to whether it maybe suits your needs
Now follows code that implements the work-part of option two, runnable as BeanShell code which does this manipulation for the current edit pane. The third line is not necessary when done in an EBComponent, this is just that the on-the-fly manipulation is shown immediately.
r = editPane.getBufferSwitcher().getRenderer();
editPane.getBufferSwitcher().setRenderer(
new ListCellRenderer() {
public Component getListCellRendererComponent(list, value, index, isSelected, cellHasFocus) {
rc = r.getListCellRendererComponent(list, value, index, isSelected, cellHasFocus);
rc.setText(value.getPath());
return rc;
}
});
editPane.repaint();
In Visual Studio C# (2008), Ctrl+M+L expand all the regions.
There's also a setting in menu:
Tools -> Options -> Text Editor -> C# -> Advanced
to not collapse during file open. I see no equivalents in VB.NET.
Is there a way to expand all the regions, not just the one which has focus in VB.NET?
Or a macro or add-in that does it? I just hate not being able to see all the code.
In Visual Studio 2012 and 2013 there is an option for deactivating collapsing (called 'outlining mode').
You can find it under:
Text-Editor->Basic->VB Specific
and then uncheck "Enable outlining mode".
But you will then lose the feature for collapse/expand at all.
If you are willing to remove regions you can try this:
Ctrl+F
Quick Replace
Find Options
Use: Regular Expressions
Find What:
^\s*#(end)?region.*$
Replace with:
[leave replace box empty]
Explanation:
^ - Match the start of a line
\s* - Match zero or more whitespace characters
# - Match one # character
(end)? - Optionally match the string end
region - Match the string region
.* - Match zero or more of any other characters
$ - Match the end of the line
This will effectively find all #region or #endregion lines, whether they are indented or not, and whether they have description text after them or not.
In the Edit Menu, the Outlining submenu, you have all the options. Including Toggle All Outlining (Ctrl+M+L by default).
Maybe your key mappings were altered.
If you so desire, you can even select menu:
Edit -> Outlining -> Stop Outlining
In VB.Net, do a Search and Replace and select Use Hidden and Use Regex:
Replace:
^.*\#(end)*(:Wh)*region.*\n
With:
I wrote an extension to do this (and more), and it works for VB and C#. See this answer for more info:
Hiding the regions in Visual Studio
Once I changed:
#Region Form Level Events
#End Region
To (note the addition of quotes):
#Region "Form Level Events"
#End Region
The minus signed appeared and I was able to collapse/expand Regions.
That's pretty odd. The default profile settings for VB.Net and C# should bind the outlining functions to Ctrl+M, Ctrl+L combos.
It's possible that your profile is in a weird state. Try resetting your profile to VB.Net settings and see if that fixes the problem.
Tools → Import / Export Settings → Reset All Settings → VB.Net Profile
I came up with this trick:
Ctrl+F
Quick Replace
Find:
#Region
Search in: current document (or entire project or wherever you need to expand regions)
Search in hidden text
Then press Return and keep it pressed until VS notify the search is endend.
As a result all your '#region's have been expanded in very few seconds.
