Environment constants

Is there an equivalant to Environment.NewLine in DotNet for a Tab character? NewLine is on the Environment class because the new line specification varies between platforms: It's "\r\n" for non-Unix platforms and "\n" for Unix platforms. However tab is always "\t". Short answer is: no, tab does not change between platforms as newline might, so there is no need for one. Long answer is: technically, yes, you could use the one provided by VB in the Microsoft.VisualBasic.dll. I think it's Microsoft.VisualBasic.Constants.vbTab, but there's no good reason to use it in C# as I said above. 来源： https:/

问题 I am stuck in deciding between choosing Google App Engine Standard Vs. Flexible environment for a real world production. I want to use Java definitely. Need to use Firebase(latest version) for Authentication and Push notification; I'm not sure whether new Firebase is compatible with standard or flexible. per the caution note in the following link, my impression is that recent Firebase is compatible is with Flexible Environment only. https://cloud.google.com/solutions/mobile/firebase-app

Setting environment variable for one program call in bash using env

由 霸气de小男生 提交于 2019-11-30 13:10:12
问题 I am trying to invoke a shell command with a modified environment via the command env . According to the manual env HELLO='Hello World' echo $HELLO should echo Hello World , but it doesn't. If I do HELLO='Hello World' bash -c 'echo $HELLO' it prints Hello World as expected (thanks to this answer for this info). What am I missing here? Cheers, Niklas 回答1: It's because in your first case, your current shell expands the $HELLO variable before running the commands. And there's no HELLO variable

update() inside a function only searches the global environment?

问题 I tried to write a wrapper function to do likelihood ratio tests in batches. I tried to include update() to update the initial model. However, it seems that instead of looking for objects inside the function, it searches for objects in the global environment. fake <- data.frame(subj= rep(1:5, 4), factor1 = rep(LETTERS[c(1,2,1,2)], each=5), factor2 = rep(letters[1:2], each=10), data=sort(rlnorm(20))) foo <- function(){ temp <- fake model1 <- lmer(data~factor1*factor2 + (1 |subj), temp) model1a

UNIX, get environment variable

由 我是研究僧i 提交于 2019-11-30 07:51:11
I have a ridiculous question due to a ridiculous problem. Normally if I want to get the contents of an environment variable in UNIX shell, I can do echo ${VAR} Let's assume, due to my ridiculous situation, that this isn't possible. How do I get the contents of an environment variable to stdout, without someone who is looking at the command itself (not the output), see the value of the environment variable. I can picture the solution being something like echo env(NAME_OF_VAR) although I can't seem to find it. The solution has to work in sh. PS I can't write a script for this, it must be a built

Distinct enclosing environment, function environment, etc. in R

由 筅森魡賤 提交于 2019-11-30 07:31:36
I have a few questions about the different environments of a function. Take the following example: environment(sd) # <environment: namespace:stats> Does namespace:stats point to the enclosing environment of function sd? pryr::where(sd) # <environment: package:stats> Does package:stats point to the binding environment of function sd? According to Advanced R by Hadley Wickham : "The enclosing environment belongs to the function, and never changes..." But the enclosing environment of function can be changed like the below: new.env <- new.env() environment(f) <- new.env A function' environment

zend framework auto switch production staging test .. etc

由 ぐ巨炮叔叔 提交于 2019-11-30 07:29:57
What do I change to switch from production to staging.. etc.. and where.. Bootstrap ? Also, Curious if anyone has configured their Zend Framework to automatically switch from production, staging, test.. etc based on Host information.. example.. if (hostname = 'prodServer') ... blah if (hostname = 'testServer') ... blah I'm new to Zend but I typically configure my projects to automatically switch run environments based on the host information. thanks Assuming that you are using APPLICATION_ENV as part of Zend_Application, then you could add this in either your .htaccess or main Apache config

Can anyone give me a example of modifying windows environment system variables in WIX?

由 ℡╲_俬逩灬. 提交于 2019-11-30 06:54:35
问题 I still don't know how to add the installdir into the PATH of the Windows System Variables after I went through the WIX tutorial. I tried to use Environment Id='UpdatePath' Action='create' Name='PATH' System='yes' Value='[INSTALLDIR]' But there was no change in the Path after I installed the program. I can hardly find sample code of WIX anywhere. Please help me, thanks a lot! 回答1: You should be able to use: <Environment Id="PATH" Name="PATH" Value="[INSTALLDIR]" Permanent="yes" Part="last"
