New ~~> symbol, and compile source and target version bump

[Ted Kosan]

In commit be4d9f73, a "~~>" symbol was added as a companion to the
"~>" symbol for handling examples that throw exceptions. See
"src/library_apps/mathpiper4/src/org/mathpiper/scripts4/testers/CheckType.mpws"
for how to use it.

In this commit, the source and target compiler settings were also
changed from 1.7 to 1.8.

Ted,

I am looking at a document I had formatted with the "->" code. It works under the pretense of the "->" but when I convert it to the "~>" it starts to throw exceptions. 

Based on the example file it doesn't seem like an appropriate time to use "~~>" but I could be wrong.

I'll keep it as the "->" until you get time to reply about what my issue might be.

Thanks!

Kyle

Kyle,

Try running the following commands:

git remote add upstream https://bitbucket.org/tkosan/mathpiperide/branch/develop

git pull upstream develop

Does the "~>" symbol work now?

I fixed the merge conflicts with my pull request and then ran the git commands. It didn't fix both of the exceptions though.

The path to this file is: mathpiperide\src\library_apps\mathpiper4\src\org\mathpiper\scripts4\mpreduce\mpreduce.mpws

It occurs with two different examples in the file, the first one is with the Solve in_prompts:

Solve([2 * _x + _y == 5, -_x + _y == 2], [_x, _y])  ~>  [_x == 1,_y == 3]

And the exception read:

***EXCEPTION[ Error encountered during parsing: Error parsing expression near token ***( Error )***. ]EXCEPTION*** , Source: STRING:USER, Line: 3, Start Index: 6

***EXCEPTION[ Error encountered during parsing: Error parsing expression near token ***( Error )***. ]EXCEPTION*** , Source: STRING:USER, Line: 3, Start Index: 6

at org.mathpiper.test.TestSuite.evaluateTestScript(TestSuite.java:418)

at org.mathpiper.test.TestSuite.runSingleTest(TestSuite.java:288)

at org.mathpiper.test.TestSuite.testPerform(TestSuite.java:179)

at org.mathpiper.test.TestSuite.testPerform(TestSuite.java:108)

at org.mathpiper.test.TestSuite.main(TestSuite.java:568)

I think updating my git repo fixed the second error I was getting in the example, but the first one is still not working but it may be an issue with the solve procedure and not necessarily with the ~> function because when I enter it into the graphic console it also shows the same exception.

In> Solve([2 * _x + _y == 5, -_x + _y == 2], [_x, _y])

Result: Exception

Exception: Error encountered during parsing: Error parsing expression near token ***( Error )***. Starting at index 6.

Thanks!

Kyle,

The problem appears to be fixed as of commit 58ab1d23;

In> Solve([2 * _x + _y == 5, -_x + _y == 2], [_x, _y])

Result: [_x == 1,_y == 3]
