I want an automatically generated include-guard by creating a new C++-class with Eclipse/CDT, but I don't find any way to change the ${include_guard_symbol} attribute.
My wish is an include-guard with a namespace prefix like following:
#ifndef NAMSPACE1_NAMESPACE2_HEADER_HPP
But if I use #ifndef ${namespace_name}_${include_guard_symbol} for this, it will produce:
namepace1::namespace2::_HEADER_HPP
How can I do this?
I had a dig around in the source for CDT, and found an undocumented preference setting you can use to change what is generated by ${include_guard_symbol}. There's no GUI for it either, but if you add the codetemplates.includeGuardGenerationScheme setting to <projectpath>/.settings/org.eclipse.cdt.ui.prefs, you can choose between file name (the default), file path or UUID.
Given the file <projectpath>/src/include/Class.h, the following values give these results:
0 gives an upper-case filename, i.e. CLASS_H_
1 gives a UUID, for example. HC9ABE718_D04E_411C_B5A2_F9FE1D9F9409
2 gives an upper-case file path, that is, SRC_INCLUDE_CLASS_H_
To avoid any doubt, here's the contents of our .settings/org.eclipse.cdt.ui.prefs:
codetemplates.includeGuardGenerationScheme=2
eclipse.preferences.version=1
formatter_settings_version=1
It's obviously not exactly what you're after, but we use 2 to give us an approximation of our namespaces since, generally speaking, our namespaces follow our folder structure.
The relevant code is in these files in the CDT source:
core/org.eclipse.cdt.ui/src/org/eclipse/cdt/ui/PreferenceConstants.java for the constants for each option
core/org.eclipse.cdt.ui/src/org/eclipse/cdt/internal/corext/codemanipulation/StubUtility.java for the generateIncludeGuardSymbol() method that does the work.
It would be really nice to see an extra option added for using the namespace, and a GUI too.
I'm using Eclipse Oxygen (CDT 9.3) and as Eelke described in their comment, there has been a UI setting for this for a while now.
However it only lets you choose from the preset schemes, no namespace or richer customisation options available yet.
Search for 'guard' in the preferences dialog, or navigate to C/C++ > Code Style > Name Style and select Code > Include Guard and then choose from the available guard schemes.

I am using this code for display my page in page content in MURA 6.1
<div>[mura]$.dspInclude('display_objects/custom/main.cfm')[/mura]</div>
But it gives me the error below:
Note: If you wish to use an absolute template path (for example,
template="/mypath/index.cfm") with CFINCLUDE, you must create a
mapping for the path using the ColdFusion Administrator. Or, you can
use per-application settings to specify mappings specific to this
application by specifying a mappings struct to THIS.mappings in
Application.cfc. Using relative paths (for example,
template="index.cfm" or template="../index.cfm") does not require the
creation of any special mappings. It is therefore recommended that you
use relative paths with CFINCLUDE whenever possible. Could not find
the included template
/muraWRM/default/includes/display_objects/custom/main.cfm.
The physical path is
[siteid]/default\includes\themes\rescue\display_objects
Thanks in advance
This should work
<div>[mura]$.dspInclude('themes/rescue/display_objects/custom/main.cfm')[/mura]</div>
Your include is being called from the includes folder, so you need to include the themes folder and the rescue folder to get to the right path.
For consistency across themes, you might want to use Mura's setting for the theme name, but I would have to look that up.
If you are ok hard coding it, this should work just fine.
Qt Creator has the Locator box, which allows you to easily find classes, methods, etc. Is there a way to use it to find class member variables, as well?
Using . <expr> will show member variables too, but that is only for searching inside the current file, not globally.
This the Locator:
By default, there is not such feature, but as said in the doc you can create a filter (I can't test it now, but I'll try this soon):
To create a locator filter:
In the locator, select Options > Configure to open the Locator options.
In the Filter Configuration dialog:
Name your filter.
Select at least one directory. The locator searches directories recursively.
Define the file pattern as a comma separated list. For example, to search all .h and .cpp files, enter *.h, *.cpp
Specify the prefix string.
To show only results matching this filter, select Limit to prefix.
Click OK.
QtCreator have no such feature - member variables are not good candidates for pivot points in search. If you want find usages of particular member, use "find symbol usages" (Ctrl+Shift+U when cursor is under symbol). If you want to find members of particular type, use usual search in regular expressions mode, something like:
\w+\s*\*\s*\w+\s*;
And limit scope to headers only (i.e use "*.h" file mask).
Have you tried using the 'Advanced...' option in the locator? You can change the scope of the search to the Current Project, All Projects, Files on the System, etc. I use this to even search for strings I use for debug output in my code.
I have kept shiftwidth as 4 in my vimrc file. But, when I open many existing c/h files, they have shiftwidth as 2. So, these gets mixed up.
Can I automatically select the shiftwidth from the file than setting it each time I open the files ?
You can add a modeline at the bottom of the file:
/* vim: set sw=2: */
More on modelines.
Modelines are not the best way to go about solving this, in my opinion. Modelines were (are?) vulnerable to a security issue. (see http://www.jukie.net/bart/blog/vim-modelines-insecure and http://secunia.com/advisories/25182/ for more information)
Instead, you can disable modelines and use a plugin to scan the files you open and automatically set shiftwidth, tabstop and others depending on the code that is there already. I use YAIFA to do this, but there are others on vim.org.
Yes, you can specify the settings from within the file itself by using a modeline, e.g.
/* vim: set ts=2 sw=2: */
For further details, see http://vim.wikia.com/wiki/Modeline_magic
In my application,I have an option of adding files to a list..were it will let the user to select multiple files at the same..am using CFileDialog to do tis and I enabled OFN_MULTISELECT (for multiselect)...The problem am facing is,When I try to add a shortcut file..its not taking the actual shortcut path,its reffering to the actual path.Actually I wanted to avoid shortcut file being added to my list,but every shortcut file that is being added does not have the extension ".lnk"(i dont know the reason).
So,is there any way that we can neglect the shortcut file being added.
You need the flag:
OFN_NODEREFERENCELINKS = 0x100000;
regards
Oops
PS: it does not neglect links from being added, but it ensures to let the link as it is. You will get files with *.lnk extensions for links. afterwards you can filter them out in you code.
I am familiar with theming and using template hints in the Magento back office to locate .phtml files.
What I am not really familiar with are the core files such as app/code/core/Mage/Catalog/Model
What I need to do is override a core file like I would a core phtml file by copying it to 'my theme'.
I basically want to amend some labels which appear on the order summary page of the Magento checkout process - domain.com/checkout/cart/
I followed the trail to the phtml files using template hints. Within the app/design/frontend/default/mytheme/template/checkout/cart I found the code
renderTotals(); ?>
Now I managed, by accident, to stumble upon two of the files I wanted to change:
/httpdocs/app/code/local/Mage/Sales/Model/Quote/Address/Total/Grand.php
/httpdocs/app/code/local/Mage/Sales/Model/Quote/Address/Total/Shipping.php
I made local copies of these files (http://www.magentocommerce.com/wiki/how_to/how_to_create_a_local_copy_of_app_code_core_mage) to override the default labels, like I would if I was overriding a template file.
My question is, how can you locate core files which pertain to the 'stuff' you want to change, located in function calls such as renderTotals(); ?> in the phtml files?
Not being able to pinpoint stuff like I can with template hints is slowing me down, and I am struggling to find a solution as I am not up on all the vocab surrounding Magento yet.
Hope this makes sense and thanks in advance!
From the same settings page where you turn on Template Path Hints, also turn on the "Add Block Names to Hints" setting. This will show you PHP class names such as: Mage_Sales_Model_Quote_Address_Total_Grand to which you can deduce the folder path (underscores represent a subfolder, and the last piece represents the file name).
If you're getting a block such as Mage_Sales_Model_Quote_Address_Total_Default then sometimes it just takes a little common sense to see that it's pulling in other files from the same folder (such as Grand.php and Shipping.php). But there are generally only a couple files in the same folder, so this is pretty easy to see.
As Sid Vel said, a good Search Project functionality is helpful. But if you find yourself looking at Abstract.php of some class, often you need to look in a subfolder in that directory with the proper name to find the concrete implementations. But still, it gets you very close to where you need to be.
I always use Dreamweaver's site / directory search function. It will scan through all the files in the Core folder and tell you where the function is from. In your case, I would search for "renderTotals". You need to enable PHTML editing in Dreamweaver.
Most IDE's will allow this kind of search option. In Aptana you can Ctrl + Click on the function to open the file it is coming from. Magento takes ages to index itself on Aptana, due to its sheer size.
