Please help me remove carriage character in JSL

I have a jsl script which calls python file to identify a specific directory from anywhere. It is working fine but he result has a carriage character which is ruining everything. 

 

cur_dir = Substr( Get Default Directory(), 2, 999 );
cur_dir = Substitute( cur_dir, "/", "\" );
show(cur_dir);
_path_script = cur_dir || "find_home_directory.py";
show(_path_script);

home_dir = RunProgram(
					executable( "python" ),
					options( _path_script),
					readfunction( "text" )
				);
show(home_dir);

 

home_dir = "C:\dtemp
";

 

Anyone , can you please help me how to convert this string to remove the carriage character and looks like this?

home_dir = "C:\dtemp"

Re: Please help me remove carriage character in JSL

@pmroz's solution is a good one! Here is a general reference to the common invisible characters that might appear in a string of characters. You can use the escape sequence to search.

Learn it once, use it forever!

cur_dir = Substr( Get Default Directory(), 2, 999 );
cur_dir = Substitute( cur_dir, "/", "\" );
show(cur_dir);
_path_script = cur_dir || "find_home_directory.py";
show(_path_script);

home_dir = RunProgram(

				);
show(home_dir);
cr ="
";
home_dir = substitute(home_dir, cr, "");
show(home_dir);

Result is still the same..:(

 

home_dir = "C:\dekel_post_processing
";
home_dir = "C:\dekel_post_processing
";

Re: Please help me remove carriage character in JSL

Although it works if you just run this few lines individually.

 

cr = "
";
home_dir = "C:\dtemp
";
show(home_dir);
home_dir = substitute(home_dir, cr, "");
show(home_dir);

Result:

home_dir = "C:\dtemp
";
home_dir = "C:\dtemp";

Re: Please help me remove carriage character in JSL

Here is how I would do it using the standard escape characters in JMP

names default to here(1);
cr = "\!r";
home_dir = "C:\dtemp
";
show(home_dir);
home_dir = substitute(home_dir, cr, "");
show(home_dir);

Which gave the reslts

home_dir = "C:\dtemp
";
home_dir = "C:\dtemp";

Re: Please help me remove carriage character in JSL

I tried it with "(\r)" as RegEx search but still getting the same issue. 

 

cur_dir = Substr( Get Default Directory(), 2, 999 );
cur_dir = Substitute( cur_dir, "/", "\" );
show(cur_dir);
_path_script = cur_dir || "find_home_directory.py";
show(_path_script);

home_dir = RunProgram(
					executable( "python" ),
					options( _path_script),
					readfunction( "text" )
				);
show(home_dir);
cr = Regex(home_dir,"(\r)");
home_dir = substitute(home_dir, cr, "");
show(home_dir);

Result.

 

home_dir = "C:\tmp
";
home_dir = "C:\tmp
";

What I want:

home_dir = "C:\tmp"

Re: Please help me remove carriage character in JSL

Maybe this?

 

cur_dir = Substr( Get Default Directory(), 2 );
cur_dir = Convert File Path( cur_dir, Windows );
Show( cur_dir );
_path_script = cur_dir || "find_home_directory.py";
Show( _path_script );

home_dir = Run Program( executable( "python" ), options( _path_script ), readfunction( "text" ) );
Show( home_dir );

home_dir = Substitute( home_dir, "\r", "" );
Show( home_dir );

Re: Please help me remove carriage character in JSL

yup finally it worked. The trick is following:

 

suppose you have a file "example.jsl" and you want to have the absolute path. You should do following:

 

cur_dir = Substr( Get Default Directory(), 2 );
cur_dir = Convert File Path( cur_dir, Windows );
Show( cur_dir );
_path_script = cur_dir || "find_home_directory.py";
Show( _path_script );

home_dir = Run Program( executable( "python" ), options( _path_script ), readfunction( "text" ) );
Show( home_dir );

path_to_example_jsl = Substitute( home_dir, "\r", "example.jsl" );
Show( path_to_example_jsl );

The python file you call is simple:

import os
def find_home_dir():
	cur_dir = os.path.dirname(os.path.realpath(__file__))
	while True:
		if "file_which_defines_root" in os.listdir(cur_dir):
			break
		else:
			cur_dir = os.path.dirname(cur_dir)
	print(cur_dir.strip())

if __name__ == '__main__':
	find_home_dir()
