## org.autoplot.jythonsupport.SimplifyScriptSupport

AST support for Jython completions. This is not meant to be thorough, but instead should be helpful when working with scripts.

## SimplifyScriptSupport( )

## alligatorParse

alligatorParse( String script ) → String

eat away at the end of the script until it can be parsed

### Parameters

script - a Jython script.

### Returns:

the script with lines at the end removed such that the script can compile.

## getIndent

getIndent( String line ) → String

return the indent for a line, for example the " " in " continue "

### Parameters

line - a String

### Returns:

the indent

## getSourceForStatement

getSourceForStatement( String[] ss, stmtType o ) → String

Using the stmtType get the line, or lines. If the last line contains a single triple-quote, we need to kludge a little and look for the preceding triple-quote in previous lines.

### Parameters

ss - a java.lang.String[]
o - a stmtType

### Returns:

a String

## removeSideEffects

removeSideEffects( String script ) → String

Remove parts of the script which are expensive so that the script can be run and completions offered. TODO: What is the difference between this and simplifyScriptToCompletions?

### Parameters

script - Jython script

### Returns:

simplified version of the script.

## simplifyScriptToCompletions

simplifyScriptToCompletions( String script ) → String

extracts the parts of the program that are quickly executed, generating a code which can be run and then queried for completions. This uses a Jython syntax tree (AST), so the code must be free of syntax errors. This will remove lines from the end of the code until the code compiles, in case the script has a partially defined def or class.

### Parameters

script - the entire python program

### Returns:

the python program with lengthy calls removed.

## simplifyScriptToGetCompletions

simplifyScriptToGetCompletions( String[] ss, stmtType[] stmts, java.util.HashSet variableNames, int beginLine, int lastLine, int depth ) → String

Extracts the parts of the program that get parameters or take a trivial amount of time to execute. This may call itself recursively when if blocks are encountered. See test038.

### Parameters

ss - the entire script, with a null at index 0.
stmts - statements being processed.
variableNames - variable names that have been resolved.
beginLine - first line of the script being processed, or -1 to use stmts[0].beginLine
lastLine - INCLUSIVE last line of the script being processed.
depth - recursion depth, for debugging.

### Returns:

the simplified script

## tryResolveStringNode

tryResolveStringNode( SimpleNode n, int row, int column, java.util.Map env ) → String

given the node n, try to resolve its string value, maybe by implementing some of the addition (concatenation). This was introduced to support URI completions within Jython codes, allowing the filename to be a variable and thus shortening lines.

### Parameters

n - node within an AST.
row - the row of the caret
column - the column of the caret
env - any variables which have been identified as string values.

### Returns:

the string or null.

## tryResolveStringNode

tryResolveStringNode( Module n, int row, int column, java.util.Map env ) → String

given the node n, try to resolve its string value, maybe by implementing some of the addition (concatenation). This was introduced to support URI completions within Jython codes, allowing the filename to be a variable and thus shortening lines.

### Parameters

n - the AST
row - the row of the caret
column - the column of the caret
env - any variables which have been identified as string values.

### Returns:

the string or null.

## tryResolveTupleNode

tryResolveTupleNode( SimpleNode n, int row, int column, java.util.Map env ) → Object[]

quick and dirty attempt to resolve tuple for format statement.

### Parameters

n - a SimpleNode
row - an int
column - an int
env - a java.util.Map

### Returns:

an Object[]
