Struct instantiation pattern "MyStruct ({...})" doesn't get parsed

[duaraghav8]

According to solidity struct doc, this should get compiled:

contract foo {
  struct fs { uint x; }
  function b () {
    if (true)
      fs ({ x: 100 });
  }
}

(compiles in solc)

However, SP throws a parse error

Error: An error occured while parsing the source code:
SyntaxError: Expected "!", "!=", "(", ")", "+", "++", "-", "--", "0", "<", "<=", "==", ">", ">=", "[", "^", "delete", "false", "hex", "mapping", "new", "this", "true", "v", "~", [1-9], comment, end of line, identifier, number, string, or whitespace but "{" found.

this is because it doesn't recognise patterns like:

foo ({ x: 100 });

where foo is:

struct foo {
  uint x;
}

Hi @duaraghav8! Are you using latest master? Rules to parse these cases were added only very recently. Are you going to try to plug SP into Solium?

[duaraghav8]

hey @cgewecke let me update my module and re-try. I AM currently working on moving to SP and deprecating solparse

[duaraghav8]

it works in 0.3.0, my bad :)

@cgewecke IDK I might be doing something stupid here, but I still can't get it to work.

when I remove the { x: 100 } from inside fs (), it gets parsed with no trouble.

using latest version

Can you please use the below code and see if SP parses it without any problems for you?

contract foo {\n  struct fs { uint x; }\n  function b () {\n    if (true) fs ({ x: 100 });\n  }\n}\n

@duaraghav8 I'm sorry I should have been clearer above - these changes are in master but haven't been published to npm yet. That segment should parse when the version gets bumped. . .

oh cool. Just let me know when you guys are planning to make the next release.
