----------------------------------------
Summary: DataExpression and StringIdentifier toString readability
Key: SYSTEMML-1173
URL: https://issues.apache.org/jira/browse/SYSTEMML-1173
Project: SystemML
Issue Type: Improvement
Components: Parser
Reporter: Deron Eriksson
Assignee: Deron Eriksson
Priority: Minor
Improve readability of StringIdentifier and DataExpression toString methods.
For example, `A = matrix("1 2 3 4 5 6", rows=3, cols=2)` in a DMLProgram
results in:
{code}
A = RAND(,lambda=1.0,min=1 2 3 4 5 6,pdf=uniform,seed=-1,max=1 2 3 4 5
6,sparsity=1.0,rows=3,cols=2 );
{code}
The extraneous first comma within RAND is confusing. Additionally, the string
'1 2 3 4 5 6' is not surrounded by quotes, which affects readability.
Readability is improved if the toStrings are modified to produce output such as
the following:
{code}
A = RAND(lambda=1.0, min='1 2 3 4 5 6', pdf='uniform', seed=-1, max='1 2 3 4 5
6', sparsity=1.0, rows=3, cols=2);
{code}
