quotes

问题 Suppose, I have function: my_function<-function(string) return(string) When I run it from R: >my_function('string"with"quotes') [1] "string\"with\"quotes" It works well. But when I try to run this function from Shell: R -e "source('./my_function.R'); my_function('string"with"quotes')" It fails with error, because shell can't deal with quotes. Is there any solution for this problem? P.S. I need to run this function directly from Shell. 来源： https://stackoverflow.com/questions/22225253/run-from

问题 Since a while I am trying to remove the quotes of my mysql query in a ZF2 application. I need to remove the quotes to make this query works, testing the query over command line succeeded by removing the quotes around GEODIST(). $adapter = $serviceLocator->get('SphinxSearch\Db\Adapter\Adapter'); $sql = new Sql($adapter); $select = new Select; $select ->columns(array('*', 'distance' => 'GEODIST(23.3556740442177, 2.9525189115381, latitude, longitude)')) ->from('table_name') ->where(array(

问题 I have a simple script which converts a text input of inches into another text input of centimeters. However, when I pass it to my function, I noticed that I have to use quotes for the argument passed to document.getElementByID. I tried newheightcm without quotes and it failed. Is there a way to avoid this to maintain consistency for both arguments, i.e. both have quotes or both have no quotes? <script> function inchestocm(IDin, IDcm) { var inches = IDin.value; var centimeters = inches*2.54;

问题 I'm using ksh and having some trouble. Why does this code not run? [root]$ CMD="ls -ltr" [root]$ eval "W=$( $CMD )" [root]$ ksh: ls -ltr: not found. [root]$ echo $W But this works fine: [root]$ CMD="ls -ltr" [root]$ eval 'W=$('$CMD')' [root]$ echo $W 回答1: You need to escape the $(...) with a backslash to prevent it from being evaluated by the outside shell. The $(...) needs be preserved as is until it is handed off to the eval : $ CMD="ls -ltr" $ eval "W=\$( $CMD )" $ echo $W total 197092

问题 I am trying to get two strings that contain quotations ("") combined as a character/string vector or with R function paste so I can plug the result in the argument x of writeFormula in openxlsx package. An example is like this paste('HYPERLINK("file)',':///"&path!$C$1&TRIM(MID(CELL("filename",B',sep="") and I hope that it should produce the result like this HYPERLINK("file:///"&path!$C$1&TRIM(MID(CELL("filename",B but it actually produces the result with a backslash in front of the ": [1]

问题 I always have my multi-line variables defined like this: var query = "\ SELECT \ this AS that \ CASE something \ FROM table \ WHERE something \ " But in Eclipse , in the default JavaScript Editor in Eclipse 3.8.0 Web Tools Platform (WTP), everytime I press return, or paste a couple of lines, Eclipse will add quotes like this: var query = "\ SELECT \ this AS that \ CASE something \ FROM table \" + " JOIN pasted.line1 \" + " JOIN pasted.line2 \" + " JOIN pasted.line3 \" + " JOIN pasted.line4 \"

问题 I've watched this clarifying keynote in which Papa Misko presents the new routing system introduced in the RC version. It's contained in the presentation the solution for the "Last Lazy Loading Puzzle Piece" , and that relies on quoting the route component name as shown in his own example: {path: 'simple', component: SimpleCmp} // Non-lazy route {path: 'simple', component: 'SimpleCmp'} // Lazy route But its not working to me! The typescript compiler is complaining though. Here is the error:

问题 I am using a regex to replace quotes within in an input string. My data contains two 'types' of quotes - " and “ There's a very subtle difference between the two. Currently, I am explicitly mentioning both these types in my regex \"*\“* I am afraid though that in future data I may get a different 'type' of quote on which my regex may fail. How many different types of quotes exist? Is there way to normalize these to just one type so that my regex won't break for unseen data? Edit - My input

问题 In Python 3.5, I have the following dictionary to be dumped into a .yaml file. D={'name': 'mydata', value: {'x': 1, 'y': 2, 'z':3}} When I run the following code: import ruamel import ruamel.yaml as yaml D={'name': 'mydata', 'value': {'x': 1, 'y': 2, 'z':3}} yaml.round_trip_dump(D, open('my_yaml.yaml', 'w'), default_flow_style=False, indent=4) The resulting my_yaml.yaml looks like the following: name: mydata value: z: 3 x: 1 y: 2 My question is, is there a handy way to write double quotes
