This is my controller method code used to get the values from Ajax call which I am printing in the log file. I am using Logger in rails to print the log file. The same data in my log file needs to be print on html.erb file. I want to display logfile data in tabular format that is why I am trying to get it in HTML file from log file. Is there any way to print logfile data into html.erb file.
How can I create map, a higher order function, in Red language. It should take a block and a function as arguments and apply the sent function to each member of block. I tried following code:
Red []
mapfn: function[blk sfn][
outblk: copy []
foreach i blk[
append outblk (sfn i) ]
outblk ]
; to test:
myblk: [" this " " is " " a " " line " "for" " testing " " only "]
probe mapfn myblk 'reverse
probe mapfn myblk 'trim
But it is not working - it simply sends back the original block without changing it or giving any error message. How can this be corrected?
In Rebol you have the mezzanine function apply
>> help apply
USAGE:
APPLY func block /only
DESCRIPTION:
Apply a function to a reduced block of arguments.
APPLY is a function value.
ARGUMENTS:
func -- Function value to apply (Type: any-function)
block -- Block of args, reduced first (unless /only) (Type: block)
REFINEMENTS:
/only -- Use arg values as-is, do not reduce the block
(SPECIAL ATTRIBUTES)
throw
See source apply.
As long as Red has no native apply you can write your own mapping function e.g
mapfn: function[blk sfn][
outblk: copy []
foreach i blk[
append outblk sfn copy i
]
outblk
]
Get the function with :functionname
>> myblk: [" this " " is " " a " " line " "for" " testing " " only "]
== [" this " " is " " a " " line " "for" " testing " " only "]
>> probe mapfn myblk :reverse
[" siht " " si " " a " " enil " "rof" " gnitset " " ylno "]
== [" siht " " si " " a " " enil " "rof" " gnitset " " ylno "]
>> probe mapfn myblk :trim
["this" "is" "a" "line" "for" "testing" "only"]
== ["this" "is" "a" "line" "for" "testing" "only"]
>>
An alternative and better way as you can not copy all datatypes is e.g.
mapfn: function[blk sfn][
collect [
foreach i blk[
keep sfn i
]
]
]
and call the function this way if no do not want to modify the original
mapfn newblk: copy/deep myblk :reverse
I am using plink to ssh to many servers and execute commands. But, unable to execute commands on console when password has special characters.
Usage: plink.exe -ssh -pw "password" user#myhost "command to execute"

Looks like when < or > appear after ", the escape does not work. Many I know how to handle this?
Realized that the issue is not with plink to escape the special characters, but with how cmd handles special characters. For this, I created a simple Java class to take the command line argument and print it:
public class MyTest {
public static void main(String args[]) {
System.out.println(args[0]);
}
}
I passed inputs with special characters to this application and here is the output:
C:\>java MyTest "apof~!##$%^&*()_+{}|:"<>?-=`[]\;',./sss"
> was unexpected at this time.
C:\>java MyTest "apof~!##$%^&*()_+{}|:\"<>?-=`[]\;',./sss"
> was unexpected at this time.
C:\>java MyTest "apof~!##$%^&*()_+{}|:\"^<^>?-=`[]\;',./sss"

From this analysis, it is found that only special character to be escaped is " and any < or > symbol occurring after alternate " has also to be escaped with ^. This document pointed me to the escape part.
Below is the python function which I have written for generating the escaped parameter:
def escapepassword(initpassword):
passsplit = list(initpassword)
quotesflag=False
index = -1
for token in passsplit:
index += 1
if quotesflag and (token in ("<", ">")):
passsplit[index] = "^" + token
else:
if token == '"':
passsplit[index] = "\\\""
quotesflag = not quotesflag
return "".join(passsplit)
Still I had issues with calling the executable with escaped arguments. I was using the following way of executing the command:
subprocess.Popen('plink.exe -ssh -batch -pw' + escapepassword(password) + ' ' + username + '#' + ipaddress + ' "' + command + '"', stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
Or to say in Java, it would be:
Runtime.getRuntime().exec("plink.exe -ssh -batch -pw" + escapepassword(password) + " " + username + "#" + ipaddress + " \"" + command + "\"");
This has given much trouble. The way python or Java execute the process is different. The special characters gets escaped and gets passed to the process. Hence, it creates much more issues. To handle this, I changed the above code to:
commandtoexecute = ['plink.exe', '-ssh', '-batch', '-pw', password, username + '#' + ipaddress, command]
subprocess.Popen(commandtoexecute, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
In Java, could be written as:
Runtime.getRuntime().exec(new String [] {"plink.exe", "-ssh", "-batch", "-pw", password, username + "#" + ipaddress, command);
Here, command had space in between, for e.g. ls -al, but this is the way to pass arguments to start a process. When I tried passing command between ", it had given error saying command not found because " was also getting passed for execution on the remote system.
Note:
I had used the command WMIC path win32_process get name,Commandline | find "plink.exe" to see the commandline arguments. The output is html escaped, however, it has helped to find the arguments passed.
How do you escape a colon, when renaming files in Ruby?
I have following code (names is a hash with data already filled in):
new_filename = ""
counter = 0
Dir.glob(folder_path + "/*").each do |f|
numbering = names.index(names.values.sort[counter])
new_filename = numbering + " - " + names.values.sort[counter]
puts "New file name: " + new_filename
File.rename(f, folder_path + "/" + new_filename + File.extname(f))
counter += 1
end
puts "Renaming complete."
The output of new_filename is correct, e.g. "Foo - Bar: Foo.txt". When it renames the file, the file has following format: "Foo - Bar/ Foo.txt".
I tried escaping with the colon with a backslash, but doesn't seem to work, because my output then looks like this: "Foo - Bar/\ Foo.txt".
Is is possible to have a colon in a string for renaming files?
FYI - in NTFS a colon identifies a separate stream of the same file... "Foo Bar: Foo.txt" identifies file "Foo Bar", stream " Foo.txt". Reference "Alternate Data Streams" (currently http://support.microsoft.com/kb/105763). AFIK this feature is not really widely used, though I have seen it used to tag files with thrid-party data (I use it to store a file's sha1 for dupe identification under the stream *:sha1).
I need to echo a series of elements of an array in PowerShell, but provide various delimiters between the elements, so I'm using;
Add-Content -Path $tempInputDir\testoutput.log -value ($($fields[0]) + " "+
$($fields[1]) + " " + $($fields[2]) + " " + $($fields[3]) + " "+
$($fields[15]) + " " + $($fields[17]))
}
I need to be able to add tabs and space characters, as you can see from the code above I've just done this by physically adding tabs and spaces in between double quotes, but I'm sure this will cause problems down the line.
What's the correct way to echo these characters to a file? I read somewhere that "'t" could be used, but that doesn't seem to work?
You can use `t for a tab character in a double quoted string. You can also simplify the above to:
"$($fields[0]) $($fields[1]) $($fields[2]) $($fields[3]) $($fields[15]) $($fields[17])" | Add-Content $tempInputDir\testoutput.log
To join the nominated fields together with tabs:
[string]::join("`t", (0..3,15,17 | % {$fields[$_]}))
