I am writing editor which must have only one instance. I use component
in fast way.
I attach minimal example.
This component uses IPC, it correct work in Windows, but now in Linux
is error:
EIPC error
Failed to create named pipe /tmp/yuniqueinstance_/<path to example>

I think, problem is with path separator? must be replaced?

Problem is with "/" in IPCClient.ServerId := GetServerId(FIdentifier)
I will replce "/" with "_"
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i   if
FileNameCaseSensitive then    UniqueInstance1.Identifier:=ParamStr(0) 
else    UniqueInstance1.Identifier:=LowerCase(ParamStr(0));  UniqueIns
tance1.Identifier:=StringReplace(UniqueInstance1.Identifier,'/','_',[r
fReplaceAll]);

Not sure why, but maybe  you should check if directory exists and that
application has proper permission to write to that directory.
