Elements command line not cooperating with me

Finally got a chance to look at this, it worked! Wondering if I did something wrong however, I am using a decompiler to review the output from the compiler and I saw this:

package test;

public final class Test
{
  private String $p_testing;
  
  private void settesting(String value)
  {
    self.$p_testing = value;
  }
  
  private String gettesting()
  {
    return self.$p_testing;
  }
  
  Test()
  {
    String str;
    self.settesting(str = "foo");
  }
}

Everything looks as expected except for the ā€œselfā€ keyword. Is that not translated to this usually? Is this an artifiact of the decompiler?

:+1:

Hard to say without (a) having your original code and (b) knowing the detailed insides of the decompiler you used and how it works. Youā€™d think a Java decompiler would emit ā€œthisā€, yes, since ā€œselfā€ (and ā€œthisā€, for that matter) is really a language syntax keyword, not a name that would get encoded into the final .jar, iā€™d expect

24

Itā€™s the same code I posted originally for context.

25

ah, ok. curious. what do you use to decompile the .jar? i assume the code works fine?

26

Havenā€™t run the code yet, just inspecting. I was using this:
http://jd.benow.ca/

Been working on getting mono to place nice with Bazel, making good
progress, soon I can run elementsCC.exe as I need.

27

ok. iā€™d say letā€™s not worry about it unless it doesnā€™t work as expected? i could escalate this for the compiler team to have a look at, but they got stuff to do as well. so unless thereā€™s an actual problemā€¦ :wink:

28

Yeah the ā€œself.ā€ reference is due to the local implicit ā€œthisā€ parameter being called ā€œselfā€ (this so the debugger can recognize it), it will show as self. in some decompilers, this is normal.

Good to know! Just an unexpected coincidence! Thanks for the advice.

So Iā€™ve almost got this working, I am getting a strange error message from elements right now:

Value cannot be null.
Parameter name: path1

I notice this happens when I give a reference to bazelā€™s internal rt.jar as a --ref. If I give it an absolute path to my OS JDK this actually works fine, but it breaks the sandbox. I am using this sandboxed command being generated by bazel:

(cd /private/var/tmp/_bazel_perezd/811f60be6a1051cf49585ebc378f1218/execroot/blockparty && \
  exec env - \
    MONO_LOG_LEVEL=debug \
    MONO_PATH=external/elements:external/elements/References/Echoes \
  external/mono/mono/bin/mono external/elements/ElementsCC.exe -d '--out=bazel-out/local-fastbuild/bin/devtools/bazel/rules/elements/examples' '--assembly=vote.blockparty.testing' '--ref=external/local_jdk/jre/lib/rt.jar' '-t=library' '-m=cooper' devtools/bazel/rules/elements/examples/Test.swift devtools/bazel/rules/elements/examples/Other.swift)

Hereā€™s the full debug log from mono if it helps:

Also, I can confirm that the rt.jar file is present at the path I am referencing.

31

Any additional thoughts on this? Let me know what else I could provide to help debug this!

EDIT: I am pretty sure that path to rt.jar is a symlink if that is interesting information.

Thanks, logged as bugs://78152

Does this mean thereā€™s a build that I can test to see if this works now?

35

itā€™ll be in next fridays beta. but i an shoot you a build earlier if you like. whatā€™s your account name on RemObjects.com?

36

should be perezd, thanks! (donā€™t have access to betas, yet, still
evaluating).

Any idea what happened there? Was it the symlink?

37

no basically it was using the project filename to find a relative reference, but the project didnā€™t exist for this commandline. bug in the code.

38

iā€™ve uploaded a new build to your personal downloads folder.

Hey there, not seeing anything here:
https://secure.remobjects.com/portal/downloads/beta.aspx

Also nothing here:

https://secure.remobjects.com/portal/downloads/personal should have it.
