RE: v13+ LEP - What is sent to OS

AFAIK it is installed per default since Win XP, I'm sure that is installed in 
Win 7 and Win 10 and of course in the matching server versions.

I will investigate further, but as I understand:
Robocopy is an EXTERNAL dos command, and as such is not (or may not) be 
installed on some/all Windows systems.

xCopy is part of command.com, and as such exists on all windows systems 
(at least all that would be in use today).

I second this recommendation. Robocopy is far better and more flexible than 
xcopy.
But the problem with escaping of paths remains the same.

Re: v13+ LEP - What is sent to OS

2018-04-11 Thread Keisuke Miyako via 4D_Tech 
typing code to the console program is not the same as calling CMD.exe via the 
CLI.

in general, with the console program, you only have to care about quoting 
arguments that contain a space because arguments are separated by space. 
however, when you call CMD.exe via the command line, you have to keep in mind 
that certain characters are escaped with a backslash, including the double 
quote. so if you have a path that ends with a backslash and you quote that 
path, you will end up escaping the closing double quote with the final 
backslash in your path. that makes the quote invalid. there is a way to double 
escape such string when passing arguments to CMD.exe via the command line.

Re: v13+ LEP - What is sent to OS

2018-04-11 Thread Keisuke Miyako via 4D_Tech 
the values you pass as the first two arguments to LEP are passed “as is” to the 
CLI (well, actually they are converted from Unicode to ANSI if you use text not 
BLOB, but that is mostly irrelevant when your locale uses English) so you can 
just examine those variables. (I advise against passing string concatenated 
values instead of variable references to $1) it is also important to check what 
you get back in stdout and stderr. you need to understand that a different rule 
applies to escaping paths vs escaping generic string. in either case, it is not 
as simple as surrounding the value with double quotes. see my old post re: 
PATH_Escape and LEP_Escape

2018-04-11 Thread Timothy Penner via 4D_Tech 
Hi Chip,

I agree with Tim Nevels' approach. It’s very solid.

Another thing to add, is that sometimes you may need to call the actual cmd.exe 
and feed your command into that, as described in this tech tip:
http://kb.4d.com/assetid=76658

On windows that would be like this:

$theRestOftheCommand:="cp thisFile here"
$command_t:="cmd.exe /C "+$theRestOftheCommand
LAUNCH EXTERNAL PROCESS($command_t)

Regarding this:
> I have done the set text to pasteboard thing, and I have pasted into a .bet 
> file -- it works.

Pasting it into a batch (I assume you meant .bat file) is not the same as 
running it in the Command Interpreter; for example, a batch file lets you 
execute multiple lines as a batch, while the Command Interpreter (and 4D's LEP) 
only lets you execute one line at a time.

Also, if the .bat file works, then you could always try executing the .bat file 
from 4D using LEP.

Thanks Tim,

I have done the set text to pasteboard thing, and I have pasted into a

I have typed - exactly - what I have for a command being fed to LEP and 
it works
run it through LEP and nothing...

That is why I want to see what LEP is feeding to the OS

Hi Chip,

Every time I am going to do a new LEP command, the first thing I do is manually 
execute it in a Command or Terminal window on macOS. I don’t even try to just 
code up the string and run it with LEP. Too many times I’ve miss a space or a 
double-quote or I’m doing the wrong thing all together.

So I first get the command working in the Terminal window. Then I copy it and 
paste it as a comment in the 4D method. For future reference. Then I write the 
code to create this command in the method. I always put the entire command in a 
text variable like $command_t.  I have a “debug” line in the method that does 
SET TEXT TO PASTEBOARD($command_t). 

Now I run LEP and if it works I’m done. If not, I do a paste into the Terminal 
window and run it and see what error messages are displayed, or I see what I 
did wrong (i.e. missed a space or a double-quote). 

That’s how I do it.

Tim
