In MSBuild, can I use the String.Replace function on a MetaData item? -

-

in msbuild v4 1 can use functions (like string.replace) on properties. how can use functions on metadata?

i'd use string.replace function below:

<target name="build">         <message text="@(files->'%(filename).replace(&quot;.config&quot;,&quot;&quot;)')" /> </target>

unfortunately outputs (not quite going for): log4net.replace(".config","");ajaxpro.replace(".config","");appsettings.replace(".config","");cachingconfiguration20.replace(".config","");cmssiteconfiguration.replace(".config","");dataproductsgraphconfiguration.replace(".config","");ajaxpro.replace(".config","");appsettings.replace(".config","");cachingconfiguration20.replace(".config","");cmssiteconfiguratio

any thoughts?

you can little bit of trickery:

$([system.string]::copy('%(filename)').replace('config',''))

basically, call static method 'copy' create new string (for reason doesn't if try $('%(filename)'.replace('.config',''))), call replace function on string.

the full text should this:

<target name="build">         <message text="@(files->'$([system.string]::copy(&quot;%(filename)&quot;).replace(&quot;.config&quot;,&quot;&quot;))')" /> </target>

edit: msbuild 12.0 seems have broken above method. alternative, can add new metadata entry existing files items. perform replace while defining metadata item, can access modified value other metadata item.

e.g.

<?xml version="1.0" encoding="utf-8"?> <project toolsversion="12.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">      <itemgroup>         <files include="alice.jpg"/>         <files include="bob.not-config.gif"/>         <files include="charlie.config.txt"/>     </itemgroup>      <target name="build">         <itemgroup>             <!--              modify existing 'files' items contain entry have done our replace.             note: needs done within '<target>' (it's requirment modifying existing items             -->             <files>                 <filenamewithoutconfig>$([system.string]::copy('%(filename)').replace('.config', ''))</filenamewithoutconfig>             </files>         </itemgroup>          <message text="@(files->'%(filenamewithoutconfig)')" importance="high" />     </target> </project>

result:

d:\temp>"c:\program files (x86)\msbuild\12.0\bin\msbuild.exe" /nologo test.xml build started 2015/02/11 11:19:10 am. project "d:\temp\test.xml" on node 1 (default targets). build:   alice;bob.not-config;charlie done building project "d:\temp\test.xml" (default targets).

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
