VScode

If the extension does not find your Julia installation automatically, or if you want to use a different Julia installation than the default one, you can set the julia.executablePath to point to the Julia executable that the extension should use. In that case the extension will always use that version of Julia. To edit your configuration settings, execute the Preferences: Open User Settings command (you can also access it via the menu File->Preferences->Settings), and then make sure your user settings include the julia.executablePath setting. The format of the string should follow your platform specific conventions, and be aware that the backlash \ is the escape character in JSON, so you need to use \\ as the path separator character on Windows.

Printing keys and values of environment variables. Takes into account path has many segments


function printKeys(keyCollection, dict)
    for key in keyCollection
        keyvalue = dict[key]
        printKeyAndValue(key,keyvalue)
    end
end

function printKeyAndValue(key,value)
    if !occursin(";",value)
        p("$key: $value")
        return
    end
    p(key)
    valueArray = split(value,";")
    foreach(x -> p("\t $x"),valueArray)
    p("")
end

A more advanced select statement in julia


#Perform case insensitive search
#for keys or values that match a case insensitve string 
re = Regex(reply,"i")

#key names where key or its value has a matching string
keynames = [key for key in keys(ENV)
        if (occursin(re,key) || occursin(re,ENV[key]))

How can I see the docs on a data type like Regex

1. Type ? at REPL

2. Type Regex (your type) and enter

3. This will show the docs from that type in that source code
