Vim has a key binding to swap two words while keeping the cursor in the same place as detailed here
:nnoremap gw "_yiw:s/(\%#\w+)(\W+)(\w+)/\3\2\1/
Unfortunately this does not seem to work in VSVim with an error reporting that the pattern could not be found: (\%\w+)(\W+)(\w+). I note that the # is missing from the pattern reported by the error message. I wonder if anyone has an idea of what the problem maybe with regex element of the binding and indeed what role the # has?
\%# in vim's regex gives the cursor position (see http://vimdoc.sourceforge.net/htmldoc/pattern.html#/\%#)
It doesn't seem to be working for me either, seems like a decent feature request, I added it here: https://github.com/jaredpar/VsVim/issues/1780
Edit:
The developer responded that this feature is out of scope for VsVim:
Unfortunately this is a feature that I can't take at this time. My regex infrastructure is based on using .NET Regex under the hood. They have no notion of cursor position and there is no way for me to translate the cursor position into a regex element. Hence there is no way to do this without creating a full regex engine from scratch which is currently beyond the scope of this project.

I'm getting an error when uploading my customized policy, which is based on Microsoft's SocialAccounts example ([tenant] is a placeholder I added):
Policy "B2C_1A_TrustFrameworkExtensions" of tenant "[tenant].onmicrosoft.com" makes a reference to ClaimType with id "client_id" but neither the policy nor any of its base policies contain such an element
I've done some customization to the file, including adding local account signon, but comparing copies of TrustFrameworkExtensions.xml in the examples, I can't see where this element is defined. It is not defined in TrustFrameworkBase.xml, which is where I would expect it.
I figured it out, although it doesn't make sense to me. Hopefully this helps someone else running into the same issue.
The TrustFrameworkBase.xml is not the same in each scenario. When Microsoft documentation said not to modify it, I assumed that meant the "base" was always the same. The implication of this design is: If you try to mix and match between scenarios then you also need to find the supporting pieces in the TrustFrameworkBase.xml and move them into your extensions document. It also means if Microsoft does provide an update to their reference policies and you want to update, you need to remember which one you implemented originally and potentially which other ones you had to pull from or do line-by-line comparison. Not end of the world, but also not how I'd design an inheritance structure.
This also explains why I had to work through previous validation errors, including missing <DisplayName> and <Protocol> elements in the <TechnicalProfile> element.
Yes - I agree that is a problem.
My suggestion is always to use the "SocialAndLocalAccountsWithMfa" scenario as the sample.
That way you will always have the correct attributes and you know which one to use if there is an update.
It's easy enough to comment out the MFA stuff in the user journeys if you don't want it.
There is one exception. If you want to use "username" instead of "email", the reads/writes etc. are only in the username sample.
Is there a such thing as a preprocessor whose statements, once processed, disappear completely and get replaced by the target language syntax permanently?
I want to research it on the web but I don't know what term to search for. If I search for "code generator", "templating language", "preprocessor directives", "mixins", "annotations" I get generators whose input becomes the source of truth.
The closest thing I can think of is a macro.
What I'm trying to do
I often have to write code that is verbose and unnecessary manual labor and am looking for a smarter way to input at least the majority of it and have it automatically transformed and only source-control the output (and hand edit if necessary). For example:
Java code - Instead of writing getters/setters, javadoc (perhaps the transformer can be a maven plugin)
HTML - I just want to add URLs, and have my preprocessor automatically convert them to links, images, videos, audio etc. depending on the file extension with some regex substitution (currently I run a perl script via a cron job)
I just want to use it as my own shorthand and not enforce it in my project and make the output editable so that others have to learn a new framework or language (like Protobuf, Stringtemplate, GWT, C hash-defines, PHP, JSP etc).
There should be no direct clue that I used a template/preprocessor to generate it.
What you want is a "program transformation system". See https://en.wikipedia.org/wiki/Program_transformation. (This is a superset of "transpilers" [ugly term]).
A good source-to-source transformation system will let you apply rewrite rules of the form of:
if you see *this*, replace it by *that* if *this_condition*.
You can then take your source code, and run a set of rewrite rules across that code to change it.
The resulting code is "transformed"; the rewrite rules are not visible.
It seems like Transpiler is one way to describe it.
I am building a search index with clucene and I want to make sure docs containing any offensive terms never get added to the index. Using a StandardAnalyzer with stop list is not good enough since the offensive doc still gets added and would be returned for non-offensive searches.
Instead I am hoping to build up a document, then check if it contains any offensive words, then adding it only if it doesn't.
Cheers!
You can't really access that type of data in a Document
What you can do is run the analysis chain manually on the text and check each token individually. You can do this in a stupid loop, or by adding another analyzer to the chain that just raises a flag you check later.
This introduces some more work, but the best way to achieve that IMO.
I'm currently using django haystack with xapian. I couldn't find any documentation on how to perform geospatial queries on xapian. But there seems to be some momentum on Solr. So i'm currently experimenting with that.
I couldn't get spatialSolr to work properly on local, but for now working with spatial-solr-light, which seems to work fine. It accepts queries like
http://127.0.0.1:8080/solr/select/?q=blahblah&spatial={!radius=1.0%20sort=true}lat:10.0,lng:-10.0
Can anyony point me to a patch for haystack that allows me to pass custom queries like that. I could use raw_search(), but i can't chain the resuts. In any case i would like to find a cleaner way to do something like
sqs.spatial(....)
There are some patches from other people mentioned on the google group(links below), but most of them are unreachable.

If you're not tied to Xapian, look at Django, Sphinx and search by distance. I had a similar problem when I ran across this question and this seems to solve it. Thanks to django-sphinx, it's about as easy to set up as Haystack. Sphinx also seems to offer more flexibility.
Here's a fork of django haystack that adds in support for :
https://github.com/sidmitra/django-haystack-spatialsolrplugin
And corresponding notes are here:
https://github.com/sidmitra/django-haystack-spatialsolrplugin/wiki/_pages
Sidmitra, I made port of your solution using haystack 1.2.X and solr 3.4. With some limitations to be frank - no support for schema generation at the moment, only LatLong geo type supported, sorting by distance is not perfect (but works)
https://github.com/frutik/django-haystack/tree/1.2.X
I agree with https://github.com/sidmitra/django-haystack-spatialsolrplugin .
It seems to be out-of-date, but I could beat it into shape with some work. Issues I had:
Hard to find the java SSP and when I found it it was the wrong version. http://www.dutchworks.nl/en/home/download.html was the link that worked for me.
The classpaths in the example xml files I found on the net were all wrong; I had to remove .solrext. from all of them.
The plugin was very picky about which directory it lived in; it couldn't talk to anything else until it was happily in solr/lib
solr_backend.py required the following patch (around line 505):
if self.spatial_query:
final_query = '{{!spatial circles={lat},{long},{radius} }}{0}'.format(final_query,**self.spatial_query)
I had further issues with making the solrconfig.xml so that GeoDistanceComponent never loaded before the query had a valid rsp.
In other words, you can certainly make it work, but you have to be able to deal with a number of error messages in both python and java before you get there.
I have a code library that makes heavy use of XPathNavigator to parse some specific xml document. The xml document is cross-referenced, meaning that an element can reference another which has not yet been encountered during parsing:
<ElementA ...>
<DependentElementX id="1234">
</ElementA>
<ElementX id="1234" .../>
The document doesn't really look like this, but the point is that 1) there is an xml schema that enforces the overall document structure, 2) elements inside the document can reference each other using some IDs, and 3) there is quite a few such cross references between different elements in the document.
The document is parsed in two phases. In the first pass I walk through the document
XPathDocument doc = ...;
XPathNavigator nav = doc.CreateNavigator();
nav.MoveToRoot();
nav.MoveToFirstChild()...
and occasionally 'bookmark' the current position (element) in the document using XPathNavigator.Clone() method. This gives me a lightweight instance of an XPathNavigator which I can store somewhere and use later to jump back to a particular place (element) in my document.
Once I have enough information collected in the first pass (for example, I have made sure there is indeed an ElementX with an id='1234'), I jump back to saved bookmarks (using those saved XPathNavigators) and complete the parsing.
Well, now I'm about to use this library in Silverlight 3.0 and to my horror the XPathNavigator is not in the System.Xml assembly.
Questions:
1) Am I missing something obvious (i.e. XPathNavigator does exist in some shape or form, for example in a toolkit or a freeware library)?
2) If I do have to make modifications in the code, what would be the best way to go? Ideally, I would like to make minimal changes, not to rewrite 80% of the code just to be able to use something like XLinq.
To resume, in case I have to give up XPathNavigator, all I need is a way to bookmark places in my document and to get back to them so that I can continue to iterate from where I left off.
Thanks in advance for any help/ideas.
You are not missing something obvious, there is no implementation of XPathNavigator or XPathDocument in the Silverlight versions of the libraries.
The "best way to go" is highly subjective and would really depend on how many lines of code are really depending on XPathNavigator. However I see a couple of choices.
Go ahead and re-write the code using XDocument, XElement etc from the System.Xml.Linq namepsace. This may not be as bad a choice as you might think.
Wrap Xml-to-Linq objects in your own implementation of those properties and methods of the XPathNavigator that you are actually using. It shouldn't be too hard re-create most the features of the XPathNavigator against the Xml-to-Linq objects. You can then run your existing code against your own XPathNavigator.
XPath (xdoc.XPathSelectElements) is available in Silverlight 4: here's an online test tool.
There are tons of ways:

You can still use Linq to XML just minus the linq syntax and use the Linq Extension methods.
