Make an escaped string in IJ macro language

[lechristophe]

Hi,

I'm trying to make a properly escaped string from a non-escaped Windows
path string, i.e.

from
C:\Users\christo\161212(test ABL b2s)\Locs\
to
C:\\Users\\christo\\161212(test ABL b2s)\\Locs\\

however both
replace(path, "\\", "\\\\")
and
replace(path, "\\", File.separator+File.separator)
throw a regex error.

How should I devise the replacement string "\\" to be handled by the
"replace" macro function?

Thanks,

Christophe

I did it with this ugly thing :

function escapePath(p) {
if (indexOf(p, "\\") > 0) {
pE = split(p, "\\");
pF = ""+ pE[0] + "\\" + "\\";
for (i = 1; i < pE.length; i++) {
pF = pF + pE[i] + "\\" + "\\";
}
}
else {
pF = p;
}
print(pF);
return pF;
}


but a proper replacement string would be nicer (could never wrap my head
around regex syntax)

Hi Christophe,

More backslashes!

path = "C:\\Users\\christo\\161212(test ABL b2s)\\Locs\\";
print("before", path);
path2 = replace(path, "\\\\", "\\\\\\\\");
print("after", path2);
