Online CamelCase to underscore_separators converter and back

Posted by jpluimers on 2016/08/09

Maintaining a suite of project that use CamelCase on the one hand and underscore_separators on the other (partially mapped by code generators) an on-line conversion comes in handy: CCConverter abedo.pl.

Push a new local branch to a remote Git repository and track it too – Stack Overflow

Posted by jpluimers on 2016/07/27

Just what I needed: Push a new local branch to a remote Git repository and track it too – Stack Overflow But watch the comments to this answer:

Answer:

In recent versions of Git (1.7.0 and later), you can checkout a new branch:

git checkout -b <branch>

Edit files, add and commit. Then push with the -u option:

git push -u origin <branch>

Git will set up the tracking information during the push.

Daniel Ruoso / Dan

Comments:

  • git push -u was introduced in Git 1.7.0 (2010-02-12). – Chris Johnsen Jun 4 ’11 at 4:16
  • Would you be kind enough to elaborate? Some git commands do more than one thing, and I’m not sure what origin and mynewfeature refer to. Is mynewfeature a branch name? Is origin a shortcut for a full remote repo url? Also what does the -u flag do? – Costa Mar 6 ’14 at 21:16
  • @Costa ‘origin’ is the name of default remote in Git repository. ‘mynewfeature’ here is branch name. -uis short for --set-upstream—for what it does and why it’s needed I wouldn’t mind some explanation, too. :) – Anton Strogonoff Mar 9 ’14 at 6:07
  • It’s also worth noting that if you have an existing tracking branch already set on the branch you’re pushing, and push.default is set to upstream, this will not do what you think it will do. It will try to push over the existing tracking branch. Use: git push -u origin mynewfeature:mynewfeature or dogit branch --unset-upstream first. – void.pointer May 19 ’14 at 18:07
  • I still needed to ‘git branch –set-upstream-to origin/remote’ in order for ‘git status’ to correctly report my branch status with respect to the remote branch. – Paul Whipp Jul 4 ’14 at 1:17
  • For people using Git from Visual Studio: Actually this is that “Publish Branch” in Visual Studio does. After executing git push with -u parameter i can finally see my branch as published in VS UI. – Puterdo Borato

C#, XSD.exe, xsd2code and generating nullable fields+properties from an XSD with and without Specified fields/properties

Posted by jpluimers on 2016/07/27

It comes down to these cases for XML elements having maxOccurs="1" (which the default for maxOccurs):

  1. adding nillable="true" will convert from a regular type to a nullable type.
  2. adding minOccurs="0" will add boolean …Specified properties in the generated C# for each element.
  3. you can have both nillable="true" and minOccurs="0" in an element which gets you a nullable type and a …Specified property.

Note I’m not considering fixed or default here, nor attributes (that have use instead of minOccurs/maxOccurs, but do not allow for nillable) nor larger values of maxOccurs (which both xsd.exe and xsd2code regard as unbounded).

From the above, XML has a richer type system than C#, so in XML there are subtle a differences between:

  1. an explicit nil in the XML element
  2. the XML element being absent
  3. the XML element being empty.

Hopefully later more text and examples to show how to actually work with this.

Delphi related to minOccurs:

Note that xsd2code.codeplex.com (unlike XmlGen#) has at least two forks at github:

A New Parser Generator for C# – CodeProject

Posted by jpluimers on 2016/07/19

A while ago I bumped into this interesting bit: LLLPG (Loyc LL(k) Parser Generator) is a new recursive-decent parser generator for C#, with a feature set better than ANTLR version 2.

csc.exe: prevent “does not contain a static ‘Main’ method suitable for an entry point”, use /target:library

Posted by jpluimers on 2016/06/29

Every once in a while I do Command-line Building With csc.exe.

When building libraries, it throws this error:

The reason is that by default it wants to build a program.

Change this default by adding the /target:library parameter.

Batch file to run the most recent vsvars32.bat

Posted by jpluimers on 2016/06/28

The below batch file finds and runs the latest vsvars32.bat on a system.

vsvars32.bat initializes the path and other environment variables to run Visual Studio and command-line tools (like csc.exe, xsd.exe, editbin.exe).

The batch file employs a few tricks from:

  :: Run the most recent vsvars32.bat

  :: test these environment variables that have 110 or 120 in them (future enhancements: support more Visual Studio versions):
  :: Visual Studio .NET 2002: VS70COMNTOOLS=C:\Program Files (x86)\Microsoft Visual Studio .NET\Common7\Tools\
  :: Visual Studio .NET 2003: VS71COMNTOOLS=C:\Program Files (x86)\Microsoft Visual Studio .NET 2003\Common7\Tools\

  :: Visual Studio 2010: VS100COMNTOOLS=C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\Tools\
  :: Visual Studio 2012: VS110COMNTOOLS=C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\Tools\
  :: Visual Studio 2013: VS120COMNTOOLS=C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\Tools\
  :: VS130COMNTOOLS was skipped: http://www.neowin.net/forum/topic/1215607-visual-studio-13-to-be-skipped-vnext-to-be-v14/
  :: Visual Studio 2015: VS130COMNTOOLS=C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools\
  :: They contain `vsvars32.bat` which will update the `PATH` so it includes where `xsd.exe`, `csc.exe`, `editbin.exe` and others reside
  :: Different examples: https://github.com/noop-dev/c-cgdk/blob/master/compile-vscpp.bat
  :: and https://code.google.com/p/xvid4psp/source/browse/trunk/bin/4Gb+patcher.bat

Writing tests for http / https request: Postman, SoapUI, Advanced REST client.

Posted by jpluimers on 2016/06/21

I’m using these Chrome Extensions for most of the http / https call mockups, and after that put them in SoapUI (which despite the name also does REST and has come a long way sinceSource: SoupUI – as sometimes that is the only thing that works):

You can get both Postman versions through GetPostman.com as well.

On Windows 7, Visual Studio 2015 wanted Internet Explorer 10… here are the direct links to download it

Posted by jpluimers on 2016/06/20

Boy, don’t you dislike how hard it is to find direct download links…

Well, thanks to kenorb and jjlin (slightly edited):

Check: IE6, IE7, IE8, IE9, IE10, IE11 Offline Installers Download Links – kenorb Mar 20 ’15 at 13:39 – http://www.itechtics.com/download-internet-explorer-all-versions/ – note this does not provide hashes.

jjlin:

Try these Microsoft offline installer links:

These may refuse to work if you already have IE 11 installed, though. If it is refused, try this: http://stackoverflow.com/questions/20043971/how-to-downgrade-from-internet-explorer-11-to-internet-explorer-10
