frepl-gui's Issues

Build failure with Java JDK 8

When I attempt to compile the project (commit 964cd77) it fails to build as shown below:

According to the instructions, it should compile with Java 8, but it seems to want Java 7. The Frege Gradle plugin was compiled to target Java 7 perhaps?

Java JDK

$ java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

OS

The OS is a Gentoo Linux (systemd-nspawn) container running on NixOS. That's why the uname info looks odd. NixOS doesn't have a JavaFX package yet, so I'm using Gentoo as a workaround; since it has the option of installing Oracle's JDK, which includes JavaFX.

uname -a
Linux gentoo 4.9.22 #1-NixOS SMP Wed Apr 12 10:41:42 UTC 2017 x86_64 Intel(R) Core(TM) i7-3615QM CPU @ 2.30GHz GenuineIntel GNU/Linux

Wish list / things to consider

I am aware of the fact that this is in a very early stage, nevertheless I think a can contribute something from the user perspective, so to speak:

  1. I find it disturbing that the text entry is above the output. Could we switch this so that it works more like a terminal, where the input line is always at the bottom? In addtion, echoed user input could be set apart visually, so that in the output window one sees better what is the answer to what.
  2. The :help window is apparently the good old Swing-Window. I am sure FX can do better and display HTML right away. (With links that don't send me to the browser ...)
  3. Despite we have multi line input, the following does not work:
    foo a b = both even a b
       where both f a b = f a && f b

It appears as if spaces before the where have been removed?
Though

:{
foo a b = both even a b
     where both f a b = f a && f b
:}

still does.

  1. In the long run, the :browse command should be obsoleted by an "outline view", like we have it in the eclipse plugin, only for all imported modules. So that one can navigate from module to type defined in that module to constructor/or function defined in that type.
  2. I have a keyboard layout, where AltGr+Letter gives me that letter in a ๐•ฑ๐–—๐–†๐–๐–™๐–š๐–— script. This does work so far in all programs, eclipse, web-browser, terminal. It doesn't in the frepl-gui, where some funny asian glyphs are substituted instead. The same happens when I copy such a letter from another window (i.e. the character map). However, when I copy the letter from the output window of the frepl (where they are occasionally correctly printed with the :t command), it suddenly accepts them!

Unable to launch the repl

Hi Dierk)

I've been trying to get Frege repl up and running but I get the following error

Error: A JNI error has occurred, please check your installation and try again

I've pretty much tried all combinations of the ./frepl command with java but still, no progress.

309  java frepl
  314  ./bin/frepl
  316  java ./bin/frepl
  317  javac ./bin/frepl
  318  sudo ./bin/frepl

Am I doing something silly here?

Build Error

I am getting an error while trying to build it with JDK8u31 on Windows. See the full log on gist. Is it something wrong with my installation? I'm trying to invoke the following simple commands:

git clone [email protected]:Dierk/frepl-gui.git
cd frepl-gui
./gradlew clean :client:run

Could not resolve all dependencies for configuration ':classpath'.

I get the following error when trying to build:

$ gradle clean :client:run

can't run this

After having resolved all of the dependency and version number problems, it still does not run.
I guess I give up for today, I spent 4 hours to get that running, and the weekend is short.
