org.autoplot.jythonsupport.JythonUtil

Utilities to support Jython scripting.

JythonUtil( )

EMPTY

createInterpreter

createInterpreter( boolean sandbox ) → InteractiveInterpreter

create an interpreter object configured for Autoplot contexts:

This also adds things to the Jython search path (see getLocalJythonAutoplotLib) so imports will find them.

Parameters

sandbox - limit symbols to safe symbols for server.

Returns:

PythonInterpreter ready for commands.

return the script description and arguments.

Parameters

script - the script Jython code.
params - any operator-defined values.

Returns:

an org.autoplot.jythonsupport.JythonUtil.ScriptDescriptor

getBeginLine

getBeginLine( java.lang.String[] ss, stmtType o ) → int

there's a problem where multi-line strings and expressions have a begin line at the end not the beginning.

Parameters

ss - the script which has been parsed into lines.
o - the AST statement

Returns:

the line of the beginning of the statement.

getDocumentation

getDocumentation( java.io.BufferedReader reader ) → Map

scrape through the script looking for documentation declarations returns an map, possibly containing:

This would originally look for lines like:
# TITLE: Text Recombinator
but this has been deprecated and scripts should use setScriptTitle and setScriptDescription

Parameters

reader - a BufferedReader

Returns:

the documentation found.

getGetDataSet

getGetDataSet( java.util.Map env, String script, java.util.Map params ) → Map

return a list of the getDataSet calls, from index to simplified getDataSet call. Experimental--interface may change

Parameters

env - a java.util.Map
script - a String
params - a java.util.Map

Returns:

a java.util.Map

support for the old getGetParams. Note this closes the reader.

Parameters

reader - a Reader

Returns:

a java.util.List

getLocals

getLocals( java.io.BufferedReader reader ) → Map

scrape script for local variables, looking for assignments. The reader is closed after reading.

Parameters

reader - the source for the script. It is closed when the code executes properly.

Returns:

a map of the local variable name to the line containing it.

join

join( java.lang.String[] list, String delim ) → String

join the array using the delimiter join( ['a','b'], '_' ) -> a_b Note Java 8 finally has a join, and this should be used when Java 8 is available.

Parameters

list - strings to join
delim - a String

Returns:

the joined string

join( java.util.List list, String delim ) → String

maybeQuoteString

maybeQuoteString( String sval ) → String

put quotes around values that appear to be strings. We see if it's parsable as a double or the keyword True or False.

Parameters

sval - the string, for example "2015" "'2015'" or "2015-01-01"

Returns:

2015, "'2015'", "'2015-01-01'"

maybeUnquoteString

maybeUnquoteString( String sval ) → String

pop off the quotes to get the text inside.

Parameters

sval - "'2015-01-01'"

Returns:

"2015-01-01"

pythonLint

pythonLint( java.net.URI uri, java.util.List errs ) → boolean

check the script that it doesn't redefine symbol names like "str"

Parameters

uri - an URI
errs - an empty list where the errors can be logged.

Returns:

true if an err is suspected.

pythonLint( java.io.LineNumberReader reader, java.util.List errs ) → boolean

readScript

readScript( java.io.Reader reader ) → String

read all the lines of a script into a string. The reader will be closed.

Parameters

reader - a Reader

Returns:

a String

removeSideEffects

Deprecated: this should not be used, because newer codes use the fully-implemented Jython parser.

setParams( PythonInterpreter interp, java.util.Map paramsl ) → void

put each parameter into the dictionary autoplot.params.

Parameters

interp - a PythonInterpreter
paramsl - a java.util.Map

Returns:

void (returns nothing)

setupInterp( PythonInterpreter interp, String pwd, String resourceUri, java.util.Map paramsl, ProgressMonitor mon ) → void

set up the interp variables scripts will often use, such as PWD and monitor.

Parameters

interp - a PythonInterpreter
pwd - a String
resourceUri - a String

simplifyScriptToGetParams

simplifyScriptToGetParams( java.lang.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. This scans through, where acceptLine is the first line we'll accept to the currentLine, copying over script from acceptLine to currentLine. See test038 (https://jfaden.net/jenkins/job/autoplot-test038/)

Parameters

ss - the entire script, ss[0] is empty string so that ss[1] is the first line of the script.
stmts - statements being processed.
variableNames - variable/procedure names that have been resolved.
beginLine - first line of the script being processed.
lastLine - INCLUSIVE last line of the script being processed.
depth - recursion depth, for debugging.

Returns:

a String

simplifyScriptToGetParams( String script, boolean addSort ) → String

splitCodeIntoLines

splitCodeIntoLines( String zerothLine, String script ) → String

one-stop place for splitting a script into lines for simplifyScriptToGetParams This was all motivated by a busy number of lineNumber-1's in the code that would handle the refactorings.

Parameters

zerothLine - null or the line to use for the first element in the array.
script - the script

Returns:

the script with the first line of the script in array[1].
