environment

When i run ant through Eclipse some targets build fine, but ones that need a specific environment variable i.e. SOME_SDK that i set in my .profile file won't work. Even if i try to echo out ${env.JAVA_HOME}, Ant through eclipse will just print out that string. But if i run ant through the terminal (i.e. ant sometarget), it will find JAVA_HOME and SOME_SDK and echo those paths out. Ive checked eclipse that it's pointing to the same ant that is in my environment path (/usr/share/java/ant-1.8.1). Any ideas? Thanks When you open a terminal, the environment variables in your .profile get loaded.

Is there any way in R6RS Scheme to obtain the current environment and then pass it as the second argument to eval ? For example, what should the question marks be for the following expression to return 9? (let ((x 4) (y 5)) (eval '(+ x y) ???)) No, there is no such thing in R6RS. Some rare implementations might support something like that, but in the overwhelming majority (including eval in other languages!) this cannot be done. The reason for that is simple: it breaks compilation, since it leads to making two functions distinguishable based on local names, and in some cases can also prohibit

I defined a function: .get <- function( o, ...) { p <- match.call( expand.dots = 0)$... cat( sprintf( 'In .get, it is %s.\n', eval( tail( p, 1)[[ 1]]))) fn <- switch( typeof( o), list =, environment = `[[`, 'S4' = '@', `[`) if( length( p)) eval( as.call( c( fn, quote( o), p))) else o # Here when true, I compose a call based on p. } Then I tried it as follows: it <- 1 m <- matrix( seq( 9), 3) sapply( seq( 3), function( it) { cat( sprintf( 'In sapply, it is: %s.\n', it)) .get( m, , it) }) sapply( seq( 3), function( it) .get( m, , it)) The output: In sapply, it is: 1. In .get, it is 1. In sapply,

I am working with conda in Windows. I accidentally installed two versions of pip using python -m pip install --upgrade pip Now when I run conda list from the base env: While pip -version gives pip 10.0.0 If I create a new env with conda create --name py3 pip and run pip --version I get an ImportError, however python -m pip --version works: How can I resolve this? First of all I tried to replicate your issue and when I updated pip to 10.0.1 using python -m pip install --upgrade pip , the command pip --version seems to work for me. I suppose it was a bug on version 10.0.0. Now coming to the

System.getenv(name) needs the name of environment variable. I am trying to call Runtime.exec(String[], String[], File), the secondary parameter need an array of environment variable, I am not sure whether subprocess will inherit environment variables from current process if I specified this parameter. For example, if I pass new String[]{"NEWDIR=/home"} as secondary parameter and current java process has environment OLDDIR=/var , what is the return value of System.getenv("OLDDIR") in the subprocess? updated: Sorry, I have to use Java 1.4 and it seems that System.getenv() was introduced in 1.5?
