JLine only works from IDEA

Question

I have no problem using jline when the code is run within idea. Running with a bat file, the edit characters are not being sent to the terminal.

java -classpath ..\JActor\target\classes;..\JID\target\classes;target\classes;..\slf4j-api-1.7.2.jar;..\slf4j-simple-1.7.2.jar;..\apache-sshd-0.8.0\lib\sshd-core-0.8.0.jar;..\apache-sshd-0.8.0\lib\mina-core-2.0.5.jar;..\apache-sshd-0.8.0\lib\bcprov-jdk15-140.jar;..\jline-2.9.jar;..\joda-time-2.1.jar org.agilewiki.jasocket.sshd.SSHServer %1%

I checked the jline jar file and it contains the fusesource code for jansi and hawtjni.

Is your terminal unicoded? – Zizith

I'm using sshd to support remote access via PuTTY. I'm confused that running from IDEA would make a difference, though I get the sense that jline expect to be interacting with the local machine. So since I'm running from a windows command window, that might me an issue. Any way to force it? – Obie

make an environment suitable to do IO in that case – Zizith

Added to my code: System.out.println(t.isAnsiSupported()); System.out.println(t.isEchoEnabled()); System.out.println(t.isSupported()); got true/false/true on dos window and false/false/true in idea. environment? like, set a system property for the terminal type? – Obie

Copy/paste command from idea console to windows cmd prompt didn't work? – Zizith

Yes, sysprop file.encoding – Zizith

that copy/paste had no effect – Obie

then add -Dfile.encoding=UTF-8, or what encoding you have in IDEA? – Zizith

I've tried jline.WindowsTerminal.ansi and jline.WindowsTerminal.directConsole to no avail – Obie

using utf-8 in idea, setting that encoding when running java has no effect – Obie

check that System.getProperty in your code and compare. – Zizith

are you running jline on the same machine? – Zizith

how about user.language, and user.country? – Zizith

yes! Only it looks like jline likes idea somehow. Now, I can force echo and local edits in putty and set the terminal type to none--that works. But that's not quite good enough for a product. :-/ And then I don't really need jline! – Obie

do you have the same value for both props, because this props could be used in character streams – Zizith

Answer 1

Turns out, the Terminal used under IDEA and the dos box were different. Forcing the use of the IDEA terminal in all cases didn't work, but this did:

    consoleReader = new ConsoleReader(in, out, new TerminalSupport(true) {});

This same issue occurs when running from within Eclipse, and then later from within Tomcat. The given fix works, although I still don't understand why even though I've been looking through the JLine2 code. – Fogbow
