spotlight

I'm developing an OS X application to organize "things" (as iTunes is to music and iPhoto to photos). Instead of having my own database and index, I'm considering using Spotlight to essentially serve this purpose. Has anyone tried this? Is it wise? The main benefit, as I see it, would be simplicity and avoiding redundancy. It seems a bit wasteful to implement my own index machinery when OS X comes with one built in. I have little experience working with Spotlight, however. From a user's perspective, I do know that it has been slow and imprecise in older versions of OS X. I also have a gut

I want to use codes like this. NSMetadataQuery *query = [[NSMetadataQuery alloc] init]; [query setSearchScopes: [NSArray arrayWithObject: [NSURL fileURLWithPath:@"/Users/Someone/Music" isDirectory:YES]]]; [query setPredicate: predicate]; ... ... Now how do I suppose to set "predicate" to filter out those files with unsupported format?? kMDItemCodezs,kMDItemMediaTypes,kMDItemContentType,kMDItemKind? Which one should I use? And what are all the possible values of these attibutes corresponding to the supported format in AVAudioPlayer in Lion 10.7? Thanks a lot. To obtain a list of most supported

上次在我的博客中讲述了quest公司的spotlight系列软件，这次来扯淡一下quest公司的另一 测试 辅助软件 datafactory（数据工厂），顾名思义，数据工厂是生产数据的，主要应用领域是性能测试中的 大数据 量测试， 也就是性能测试数据准备阶段。 原理说明： 通过和 数据库 进行连接后，对选定表的字段设定一定的插入规则，然后批量插入记录。Datafactory支持各种主流数据库（ Oracle 、DB2、MS SQL），甚至excel、access等。下面以以主流的oracle为例进行说明。 环境说明： Oracle10g，创建2个表，一个是testtable，一个testtable2。计划用datafactory往testtable中插入记录，其中需要读取testtable2中的部分字段信息。testtable表的字段类型如下（字段类型已经尽可能覆盖多种情况）： Testtable表： Testable2字段类型和testtable类似，里面记录情况如下： 编号 姓名 性别 出生日期 毕业院校 分数 照片 考核情况 1 张三 1 2009-12-21 北京大学 85.5 <BLOB> <NCLOB> 2 李四 0 2002-7-16 清华大学 78.2 <BLOB> <NCLOB> 3 王五 1 1999-6-8 湖南大学 65.5 <BLOB> <NCLOB>

I noticed that when I search for "Music" (for example) using Spotlight on the iPhone OS 3.0, the app "Midomi" shows up in the Spotlight results. "Midomi" doesn't exactly match "Music", but yet it appears in the results. How can I specify additional keywords for my app so it appears when doing a search using Spotlight, like Midomi is doing? Midomi's full name is Midomi Music Identifier and Search (Ultra) . Therefore the search term 'music' will cause Spotlight to list the Midomi application. Spotlight searches both names as they appear in SpringBoard (your home screen) and their full App Store

I cannot seem to get what I am doing wrong -- probably not understanding how shaders work! I get the first light fine but no sign of the effects of the second one (aka spotlight). Here is the fragement shader that I came up with: varying vec4 diffuse,ambientGlobal, ambient; varying vec3 normal,lightDir,halfVector; varying float dist; void main() { vec3 n, halfV, viewV, ldir; float NdotL, NdotHV; vec4 color = ambientGlobal; float att, spotEffect; n = normalize(normal); NdotL

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: It was mentioned that we can execute a shell script using spotlight renaming it as "myscript.command" as described here . But is it possible to pass a parameter to the script when calling it from Spotlight? For example: Script myscript.command: #!/bin/bash echo "Parameter: " $1 On Spotlight: myscript.command test Output: (...) Parameter: test (...)

Is it possible to extend spotlight's search feature to support additional commands? For example, is it possible to define custom web search aliases, meaning I could type yt and it would provide results from youtube. Alternatively, is it possible to add additional system commands were I could type sl (or some variant) to put my computer to sleep. No it is not possible, there are only 4 types of extensions for OS X Yosemite : Today - Get a quick update or perform a quick task in the Today view of Notification Center Share - Post to a sharing website or share content with others Action -
