2. Re: file_exists and file name in quotes

Are you saying you are trying something like this ...

sequence filename 
 
filename = "\"My File With Spaces.txt\"" 
 
if file_exists(filename) then 
    system_exec("somecmd " & filename) 

And file_exists() always reports the file as missing?

If so, I think that this is not a bug. There are many library routines that take a file name as a parameter, and none of them (as far as I can remember) strip off enclosing quotes.

Note that the system_exec() routine does not take a file name as a parameter, instead it takes a command line as a parameter and it is the command line that needs quoted files.

May I suggest that you code more like this instead ...

sequence filename 
 
filename = "My File With Spaces.txt" 
 
if file_exists(filename) then 
    system_exec(sprintf(`somecmd "%s"`, {filename}))

Well, it seems like you have defined the EDITOR symbol to have quotes around the file name. If this is how you want it to stay then you will need to strip off the quotes.

function dequote_env(sequence name) 
    object res 
    res = getenv(name) 
    if sequence(res) then 
        if length(res) >= 2 then 
            if res[1] = '"' and res[$] = '"' then 
                res = res[2..$-1] 
            end if 
        end if 
    end if 
 
    return res 
end function 
sequence editor = dequote_env("EDITOR") 
 
if not file_exists(editor) then 
	editor = dequote_env("WINDIR") & "\\notepad.exe" 
end if 
 
system_exec(sprintf(`"%s"`, {editor})
