I have
myVar.value = 123521#machine OK
now I'm using this variable with system command as it's an argument passed to a binary .exe
so I have to add quotes to myVar.value as it caontains spaces
I tried :
'''myVar.value''' but this will give 'myVar.value', whereas I just want to have the result equal to "123521#machine OK"
how could I use the quotes in this case ?
Try this:
x = ['"' myVar.value '"']
I think you can use double quote characters within strings demarcated by single quotes. Within a string demarcated by single quotes characters by doubling up:
x = ['''' myVar.value '''']

I have a powershell script which calls another powershell file passing a string argument.
param (
[string]$strVal = "Hello World"
)
$params = #{
message = "$strVal"
}
$sb = [scriptblock]::create(".{$(get-content $ps1file -Raw)} $(&{$args} #params)")
Somehow the script passes message variable without double quotes so the powershell file receives only the first part of the message variable (before space) i.e. "Hello".
How can I pass the strVal variable with space (i.e. "Hello World")?
A double quote pair signals PowerShell to perform string expansion. If you want double quotes to output literally, you need to escape them (prevent expansion) or surround them with single quotes. However, a single quote pair signals PowerShell to treat everything inside literally so your variables will not interpolate. Given the situation, you want string expansion, variable interpolation, and literal double quotes.
You can do the following:
# Double Double Quote Escape
#{message = """$strVal"""}
Name Value
---- -----
message "Hello World"
# Backtick Escape
#{message = "`"$strVal`""}
Name Value
---- -----
message "Hello World"
Quote resolution works from left to right, which means the leftmost quote type takes precedence. So '"$strVal"' will just print everything literally due to the outside single quote pair. "'$strVal'" will print single quotes and the value of $strVal.
my #para_text = $mech->xpath('/html/body/form/table/tbody/tr[2]/td[3]/table/tbody/tr[2]/td/table/tbody/tr[3]/td/div/div/div', type => $mech->xpathResult('STRING_TYPE'));
#BELOW IS JUST TO MAKE SURE THE ABOVE CAPTURED THE CORRECT TEXT
print "Look here: #para_text";
$mech->click_button( id => "lnkHdrreplyall");
$mech->eval_in_page('document.getElementsByName("txtbdy")[0].value = "#para_text"');
In the last line of my code I need to put the contents of the #para_text array as the text to output into a text box on a website however from the "document" till the end of the line it needs to be surrounded by ' ' to work. Obviously this doesnt allow interpolation as that would require " " Any ideas on what to do?
To define a string that itself contains double quotes as well as interpolating variable values, you may use the alternative form of the double quote qq/ ... /, where you can choose the delimiter yourself and prevent the double quote " from being special
So you can write
$mech->eval_in_page(qq/document.getElementsByName("txtbdy")[0].value = "#para_text"/)
I want to remove characters within parentheses from a string in MATLAB:
For eg: I have the string
S(+42.01)DKHDKPDISEVTKFDKSKLKKTETHEKNPLPTKETIDQEKQG
but want to remove the parentheses and store :
SDKHDKPDISEVTKFDKSKLKKTETHEKNPLPTKETIDQEKQG
The characters in parentheses could be text, numbers, combination of text numbers and special characters. Also the parentheses can occur multiple times in the same string.
Thanks
There you go:
x = 'Q(-17.03)VAQMHVWRAVNHDRNHGTGSGRH(-.98)';
y = regexprep(x, '\([^\(\)]*\)',''); % detect substring formed by
% parentheses and anything in between that is not a parenthesis,
% and replace that by an empty string
gives
y =
QVAQMHVWRAVNHDRNHGTGSGRH
How do I pass double quotes as a parameter in powershell? For example, I need to execute this line but K="Key words" has to be in double quote
$Ie.Navigate2("http://inside.nv.com/demo/Search/Pages/results_Table.aspx?k="Boiling Point"(CreatedBy:Broussard AND Write>=6/1/2015 AND Write<=6/30/2015)", 0x10000)
Try to escape the " which is part of the parameter string with
`
so, in your case it will be like below -
$Ie.Navigate2("http://inside.nv.com/demo/Search/Pages/results_Table.aspx?k=`"Boiling Point`"(CreatedBy:Broussard AND Write>=6/1/2015 AND Write<=6/30/2015)", 0x10000)
Use encoding. The (") character would correspond to %22.

I need to make some Windows file paths that contain spaces into string literals in Scala. I have tried wrapping the entire path in double quotes AND wrapping the entire path in double quotes with each directory name that has a space with single quotes. Now it is wanting an escape character for "\Jun" in both places and I don't know why.
Here are the strings:
val input = "R:\'Unclaimed Property'\'CT State'\2015\Jun\ct_finderlist_2015.pdf"
val output = "R:\'Unclaimed Property'\'CT State'\2015\Jun"
Here is the latest error:
The problem is with the \ character, that has to be escaped.
This should work:
val input = "R:\\Unclaimed Property\\CT State\\2015\\Jun.ct_finderlist_2015.pdf"
val output = "R:\\Unclaimed Property\\CT State\\2015\\Jun"
A cleaner way to create string literals is to use triple quotes.
You can wrap your string directly in triple quotes without escaping special characters. And you can put multiple lines string in it.
It's much easier to code and read.
For example
val input =
"""
|R:\Unclaimed Property\CT State\2015\Jun.ct_finderlist_2015.pdf
"""
To add a variable to the string, do it like the following by adding "$variableName".
val input =
s"""
|R:\Unclaimed Property\$variablePath\CT State\2015\Jun.ct_finderlist_2015.pdf
"""
