In Oracle SQL Developer version 4.0.1.14, there's a setting named "Autoformat visible SQL" but I can't figure out what it does, or whether it's broken.
According to the built-in F1 help, it should format my code while I type it:
Autoformat PL/SQL in Procedures, Packages, Views, and Triggers: If this option is checked, the SQL Formatter options are applied automatically as you enter and modify PL/SQL code in procedures, packages, views, and triggers; if this option is not checked, the SQL Formatter options are applied only when you so request.
The help heading is slightly different than the screenshot, but there is no other occurrence of "autoformat" anywhere in Help.
Since version 4.2 this option is available under "Code Editor" -> "Format". It's still available in Version 20.2.
This option has no affect on the worksheet nor on the PL/SQL editor. AFAIK it only affects the "SQL" tab for database objects that are opened e.g. via the "Connections" window. For example tables, views, triggers. For these objects, the code is read from the database and then automatically formatted according to your formatting settings, if the option "Auto formatting of visible SQL and PL/SQL" is checked.
This SQL tab is read-only and the formatter cannot be invoked there. Therefore I consider the help text wrong or at least misleading.

I type pretty fast so I want MySQL Workbench to auto-capitalize keywords after I type them. I've seen a solution to a similar question which is MySQLWorkbench-> Preferences-> Query Editor-> Change keywords to UPPER CASE. However this only provides uppercase for autofill. The problem is that the dropdown menu takes a second to load and hinders my work flow.
Is there any solution to this problem? Could I create a trigger for this or is that not helpful?
Not an automatic solution but something useful: look in the Edit -> Format menu. It has entries to upcase + downcase keywords, as well as other formatting commands.
With sublime text 3, the autocomplete when typing "for" and hitting tab gives you:
for x in xrange(1,10):
pass
However, this is not a valid statement for python 3. I've tried creating a new build system using the following:
{
"cmd": ["c:/Python37/python.exe", "-u", "$file"],
"file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
"selector": "source.python"
}
the auto-complete for for still gives the wrong syntax. any advice?
The short version is that the sublime-build and sublime-snippet files that ship with Sublime in support of Python target Python version 2 and not Python version 3. I don't know if that's just due to that being what was used initially or if it's being done on purpose, though.
In Sublime, resources are generally related to a particular language based on the scope provided by the syntax definition. So for example snippets for Python are associated with source.python, your example build file uses that scope to know that it applies to Python files, and so on. As such, no matter what build you happen to be using, that has no effect on the snippets that are being offered.
By way of example, if you use the View Package File command from the command palette and enter the text python for snippet, the list of package resources will filter to Python/Snippets/for.sublime-snippet; pressing Enter to view that resource shows this:
<snippet>
<tabTrigger>for</tabTrigger>
<scope>source.python</scope>
<description>For Loop</description>
<content><![CDATA[
for ${1:x} in ${2:xrange(1,10)}:
${0:pass}
]]></content>
</snippet>
Here the tabTrigger specifies how the snippet inserts, scope controls where it inserts and content controls what it is inserts. Thus, in order to change it to support Python 3, you need to either create your own snippet or modify the existing one.
An issue with creating your own snippet is that it will be added to the list of snippets including the offending one, which allows it to possibly still trigger when you don't expect it to. There is also no general purposes "easy" way to disable individual snippets.
As such, generally the best course of action would be to use the PackageResourceViewer package. Install it, select PackageResourceViewer: Open Resource from the command palette, then select the same file as outlined above and modify the content of the snippet (e.g. replace xrange with range) and save the file.
That will get Sublime to replace the existing snippet with your edited version, so that it takes the place of the existing one and works the way you want.
Is there a way to select a C/C++ expression in Eclipse and put a bracket around it with a single keyboard shortcut? IDEs usually have this but I couldn't find a way in Eclipse.
For Java Code, there is a more or less good workaround described in Parentheses over selected words in Eclipse, but this does not work for C-Code - after bringing up the template list for the selection, the suggested templates are empty.
As far as I know, exactly that is not possible. You might report it to Eclipse CDT as a feature request.
But as workaround a template like the following can be used:
(${line_selection})${cursor}
If you hit Shift+Alt+Z the Surround With Quick Menu shows all templates containing ${line_selection} and with a number key a templated can be selected.
The key Shift+Alt+Z can be changed, but unfortunately no key can be defined to select the template directly. Also unfortunately, this does not work for multi-line selections because everything in the template in the line before ${line_selection} will be applied to each selected line.
Today I have question about Eclipse. I use this IDE very long and I think it is good, but last time I miss for some functionalities...
Is it possible to set some shortcut which will do something like:
Mark some text ('Hello world'), trigger shortcut (Ctrl+T) and it will do something with that text - in example adds text before and after selected text ($this->_('Hello world'))
?
Thanks for any sugestion !
From this, it appears you have to implement your own command in a plugin. The process looks more involved than simply setting a menu choice.
Equivalent functionality can be defined without commands, if you're willing to give up the keyboard shortcut and use content assist instead.
I'm not sure if it will work with the language you're using (PHP?), but with Java in Eclipse it is possible to use Code Templates.
You would define your own template, when it was applicable and what it would do. This could then be accessed with Ctrl+Space through the possible content assist methods. So in the context of Java statements, I can define:
this.call(${word_selection});
So when I highlight a word, such as "Hello, world", I can use the template to change it to:
this.call("Hello, world");
(There are ways to limit it to only String types instead of word selections, but that will most likely not apply to your language, so I didn't pursue exactly how to do it.)
The Code Templates menu is available through Window->Preferences.
Good file comparison tools were already discussed to the pain, but my problem is more exotic. Is there any visual text comparison tool (like WinMerge) that would allow me easily do visual comparison on two sections within the same file?
I have multiple configurations within vcproj file and need to maintain them. It is a pain to do this manually -- splitting windows, scrolling character-by character. On top of that xml is very verbose and takes lots of screen real-estate. I cannot believe there is no tool to do automatic file section comparison, since this sounds like a very common problem.
Please, do not offer me to use property pages, I do not want more complexity, I want less. Splitting manually into files and then comparing them is also too medieval (I am doing this now anyways).
I use Beyond Compare (not free, but I think a shareware version is available). You can select the same file for left and right sides, then right-click the beginning of your section on each side and select "Align Manually". This would allow you to compare two sections of the same file relatively easily.
Overall, I highly recommend the product. I haven't tried version 3, which is what they currently have on their Web site, but version 2 is a fabulous tool. A+

I use UltraEdit for most of my text editing and they have a product called UltraCompare that does a visual compare.
Update by Mofi
UltraCompare Professional supports also a comparison of text snippets in addition to entire files.
After starting UltraCompare, select Text Compare in menu Mode if not already selected. Select in text editor the first text block which should be compared, press Ctrl+C, switch back to UC and paste with Ctrl+V the block into left text area pane. Switch again to text editor, select the other block in same file, press Ctrl+C, switch back to UC, click into right pane and paste the block with Ctrl+V. The two blocks are immediately compared and the differences are displayed.
Such a text snippet comparison for two blocks in same file can be started also directly from within UltraEdit. Select the first block in file, press Ctrl+C, Ctrl+N, Ctrl+V and Ctrl+A to copy, paste and reselect this block in a new file. Select the second block in file. Execute command Compare from menu File in UltraEdit with option Compare selected text automatically being enabled and click on button Compare. UC Professional is started with just the 2 selected blocks for comparison.
You can use Meld to do this
Open up meld without specifying file names
Meld with prompt which type of comparison you want. Choose file comparison
Meld will present the the icon to select the file names. Below that it will prompt for a Blank comparison. Choose that.
In the file comparison window, paste the sections of the file you want to compare.
