Why do lane control keys work for me using lein1 but not lein2?

Question

I successfully upgraded to lein2 and successfully completed lein repl . I use VanDyke SecureCrt to log in to a Ubuntu 12.04 workstation. I did not change any terminal settings and did not have the following problem with lein 1.x.

When I went to use my usual bash command-line keys, such as CTRL + A, CTRL + E, and CTRL + C, none of these keys worked.

What do I need to do to enable these CTRL keys?

Following the installation instructions, I saved the original lane as lein1. I tried this and the control keys work as above.

I tried installing lein2 for a new user, instead of updating, and the key problem persists. I also tried this on CentOS and Ubuntu systems. The same behavior exists.

Here is the result from stty -a

38400 baud rate; line 42; columns 159; line = 0; intr = ^ C; quit = ^ \; erase = ^ ?; kill = ^ U; eof = ^ D; eol =; eol2 =; swtch =; start = ^ Q; stop = ^ S; susp = ^ Z; rprnt = ^ R; werase = ^ W; lnext = ^ V; flush = ^ O; min = 1; time = 0; -parenb -parodd cs8 -hupcl -cstopb cread clocal -crtscts -ignbrk brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl ixon -ixoff -iuclc -ixany imaxbel -iutf8 opost -olclocron ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0 Source Code cnorton @steamboy: ~ / projects / clojure / wtr-usage1 $

Here is the result of the new lein:

 nREPL server started on port 52310 REPL-y 0.1.9 Clojure 1.4.0 Exit: Control+D or (exit) or (quit) Commands: (user/help) Docs: (doc function-name-here) (find-doc "part-of-name-here") Source: (source function-name-here) (user/sourcery function-name-here) Javadoc: (javadoc java-object-or-class-here) Examples from clojuredocs.org: [clojuredocs or cdoc] (user/clojuredocs name-here) (user/clojuredocs "ns-here" "name-here") wtr-usage1.core=> 

Are there any directories or files that need to be cleaned between lein 1 and 2? I have no plugins, so there was no part of the update.

I continued to work on this issue and performed the following diagnostic tests:

1) I executed the following command

 java -cp target/jline-2.11-SNAPSHOT-tests.jar:target/jline-2.11-SNAPSHOT.jar -Djline.internal.Log.debug=true jline.example.Example none 

in the cloned jline2 directory. The control keys did not work.

2) I executed the following command

export JLINE_LOGGING=trace && lein trampoline run

in the cloned git clone git://github.com/trptcolin/reply.git directory git clone git://github.com/trptcolin/reply.git - reply. The control keys worked. I was asked to create an issue on github, which I did.

Answer 1

At the suggestion of A. Webb, I am sending github message # 79 to jline as a response. This works with the term, but not with my SecureCrt. SecureCrt had no problems with lein1.

Control keys do not work and the ~ / .jline.rc file does not disappear

No milestones No one assigned

(I went ahead and created a ~ / .jline.rc file containing jline.terminal = auto since this problem was written.) My problem is that my control keys do not work, and what can I do to get around this problem.

Here is a description of what I did.

I run

java -cp target / jline-2.11-SNAPSHOT-tests.jar: target / jline-2.11-SNAPSHOT.jar -Djline.internal.Log.debug = true jline.example.Example none

in my ~ / jline2 directory where I installed jline2. My control keys (ctrl + a, ctrl + e, ctrl + u and Backspace) do not work.

I log in to Ubuntu 12.04 with bash as a shell and use the VanDyke SecureCrt terminal emulator product. I have not made any changes to the settings of my emulator.

Firstly, I noticed that I do not have the file ~ / .jline.rc [DEBUG] Loading properties from the file: /home/cnorton/.jline.rc [DEBUG] Unable to read the configuration from the file: / home / cnorton /. jline.rc java.io.FileNotFoundException: /home/cnorton/.jline.rc (There is no such file or directory)

After the stack trace, here is the rest of the output.

Here is another debug output from

Answer 2

This should not happen. Try running set -o emacs in bash, but there should be nothing in the script lane to disable it.

Answer 3

Try reinstalling leiningen. lein2 repl in my configuration starts REPL-y, it looks like this:

 % lein2 repl Downloading Leiningen to /home/dpx-infinity/.lein/self-installs/leiningen-2.0.0-standalone.jar now... % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 12.6M 100 12.6M 0 0 93665 0 0:02:21 0:02:21 --:--:-- 91018 nREPL server started on port 47543 REPL-y 0.1.9 Clojure 1.4.0 Exit: Control+D or (exit) or (quit) Commands: (user/help) Docs: (doc function-name-here) (find-doc "part-of-name-here") Source: (source function-name-here) (user/sourcery function-name-here) Javadoc: (javadoc java-object-or-class-here) Examples from clojuredocs.org: [clojuredocs or cdoc] (user/clojuredocs name-here) (user/clojuredocs "ns-here" "name-here") user=> 

REPL-y has all the usual editing commands. If you do not understand this, there must be something wrong with your installation.

Answer 4

I suggest you test the new installation of the new lein in a new fresh environment:

• Create new user: sudo useradd -m testlein
• Go to new user: sudo su - testlein
• Get the latest lein2: wget https://raw.github.com/technomancy/leiningen/stable/bin/lein
• Set execute permission: chmod +x lein
• Install lein: ./lein
• Run answer: ./lein repl

After that, try ctrl-a / e / ....

PS I do not know how you installed java on your system. You may need to configure java in your new user environment before step 5.

Answer 5

This seems to be a problem with JLine on Cygwin . Trying the same workaround your system is worth it.

Modify the lein script starting at line 284 as follows; added lines are indicated by the symbol -> .

  export TRAMPOLINE_FILE -> stty -icanon min 1 -echo "$LEIN_JAVA_CMD" \ -client -XX:+TieredCompilation \ "${BOOTCLASSPATH[@]}" \ $LEIN_JVM_OPTS \ -Dfile.encoding=UTF-8 \ -> -Djline.terminal=jline.UnixTerminal \ -Dmaven.wagon.http.ssl.easy=false \ -Dleiningen.original.pwd="$ORIGINAL_PWD" \ -Dleiningen.script="$SCRIPT" \ -classpath "$CLASSPATH" \ clojure.main -m leiningen.core.main " $@ " -> stty icanon echo EXIT_CODE=$?
