Support target artifact selection in JSON I/O #2146

axic · 2017-04-20T19:17:51Z

Fixes #2897. Depends on #2729.

axic · 2017-04-20T22:38:44Z

libsolidity/interface/StandardCompiler.cpp

+bool isTargetRequired(Json::Value const& _targets, string const& _target)
+{
+	for (auto const& target: _targets)
+		if (target == _target)


Need to support sub matches, e.g. evm.assembly should be enabled by both evm.assembly, evm, evm.*, etc.

@chriseth do you have any code suggestion for doing so? E.g. requiring evm.assembly matches both the user supplied evm.assembly, evm.* and evm, without hardcoding these paths.

chriseth · 2017-07-13T13:03:22Z

What is left to do here? Can you work on this next, @axic?

axic · 2017-07-13T23:16:46Z

Reviewed it again, I think the API (isTargetRequired) and the part using it is clear enough, but the actual implementation is broken, hence the tests failures.

It also doesn't support wildcards properly and shortest match.

axic · 2017-08-10T18:59:47Z

Need to add tests for matching different combinations (evm, evm.*, evm.assembly, etc.)

test/libsolidity/StandardCompiler.cpp

+		},
+		"outputSelection": {
+			"fileA": {
+				"A": [ "abi", "devdoc", "userdoc", "evm", "metadata" ]


This is annoying, one of the reasons for the failing tests was a missing comma here at the end 😕

chriseth · 2017-10-18T16:25:02Z

Changelog.md

 Features:
 * Parser: Better error message for unexpected trailing comma in parameter lists.
- * Standard JSON: Support the ``outputSelection`` field for selective compilation of supplied sources.
+ * Standard JSON: Support the ``outputSelection`` field for selective compilation.


Please move to 0.4.19

axic · 2017-10-19T10:11:50Z

Depends on argotorg/solc-js#159.

axic · 2017-10-19T13:23:09Z

@chriseth This is working now (as confirmed by circleci). It still needs support for shorcuts (e.g. evm.bytecode matching evm.bytecode.object)

axic · 2017-10-19T14:05:50Z

@chriseth can you review this? it may be worth even merging it in this state, though more tests cannot hurt.

chriseth · 2017-10-19T14:11:48Z

solc/jsonCompiler.cpp

 	input["settings"]["optimizer"]["runs"] = 200;

+	// Enable all SourceUnit-level outputs.
+	input["settings"]["outputSelection"]["*"][""][0] = "*";


Does [0] automatically make it an array?

Yep. Had an ugly large code before to do it manually.

chriseth · 2017-10-19T14:16:44Z

libsolidity/interface/StandardCompiler.cpp

 	return sources;
 }

+bool isTargetRequired(Json::Value const& _targets, string const& _target)


Perhaps better requested than required?

Sure, but also please see my other naming suggestion below.

chriseth · 2017-10-19T14:20:32Z

libsolidity/interface/StandardCompiler.cpp

+			{
+				/// Special case for SourceUnit-level targets (such as AST)
+				if (
+					_targets[file].isMember("") &&


Can you extract this condition into a function and also use it in line 129?

axic · 2017-11-22T13:35:41Z

@chriseth I think this should be ready now?

axic · 2017-11-22T16:31:00Z

@chriseth added two more commits to simplify/optimize it even more (last 3 commits should be squashed). Please check those two.

chriseth · 2017-11-23T17:59:36Z

Looks good!
