Table of Contents
| Name | Direction | Type | Default | Description |
|---|---|---|---|---|
| InputWorkspace | Input | Workspace | Mandatory | An input workspace. |
| Filename | Input | string | The name of the file into which the workspace history will be generated. Allowed extensions: [‘.py’] | |
| ScriptText | Output | string | Saves the history of the workspace to a variable. | |
| UnrollAll | Input | boolean | False | Unroll all algorithms to show just their child algorithms. |
| StartTimestamp | Input | string | The filter start time in the format YYYY-MM-DD HH:mm:ss | |
| EndTimestamp | Input | string | The filter end time in the format YYYY-MM-DD HH:mm:ss | |
| AppendTimestamp | Input | boolean | False | Appends the time the command was run as a comment afterwards |
| SpecifyAlgorithmVersions | Input | string | Specify Old | When to specify which algorithm version was used by Mantid. Allowed values: [‘Specify Old’, ‘Specify All’, ‘Specify None’] |
| IgnoreTheseAlgs | Input | str list | A list of algorithms to filter out of the built script | |
| IgnoreTheseAlgProperties | Input | list of str lists | A list of algorithm properties to filter out of the built script | |
| AppendExecCount | Input | boolean | False | Whether execCount should be appended to the end of the built string |
Retrieves the algorithm history of the workspace and saves it to a Python script file or Python variable.
A time range can be specified which will restrict the algorithms in the scrit to those which were executed between the given times, if no end time was specified then algorithms from the start time up to the current time will be included in the generated script.
Start and end times are given in ISO8601 format: YYYY-MM-DD HH:mm:ss, for example 3:25 PM on July the 4th 2014 would be 2014-07-04 15:25:00.
Example - generate a python script for a workspace:
#create a workspace and run some operations on it
ws = CreateSampleWorkspace()
ws = CropWorkspace(ws, XMin=7828.162291, XMax=11980.906921)
ws = Power(ws, Exponent=1.5)
ws = RenameWorkspace(ws, OutputWorkspace="MyTestWorkspace")
script_text = GeneratePythonScript(ws)
print(script_text.strip())
Output:

from mantid.simpleapi import *
CreateSampleWorkspace(OutputWorkspace='ws')
CropWorkspace(InputWorkspace='ws', OutputWorkspace='ws', XMin=7828.1622909999996, XMax=11980.906921)
Power(InputWorkspace='ws', OutputWorkspace='ws', Exponent=1.5)
RenameWorkspace(InputWorkspace='ws', OutputWorkspace='MyTestWorkspace')
Example - generate a python script giving a range of start times:
import time
# Do some operations on the workspace with a pause between them
ws = CreateSampleWorkspace()
ws = CropWorkspace(ws, XMin=7828.162291, XMax=11980.906921)
time.sleep(2)
ws = Power(ws, Exponent=1.5)
ws = RenameWorkspace(ws, OutputWorkspace="MyTestWorkspace")
# Get the execution time of the last algorithm and subtract 1 second
history = mtd['MyTestWorkspace'].getHistory()
last = history.getAlgorithmHistory(history.size() - 1)
from_time = last.executionDate() - int(1e9)
# Generate a script with a given start time
script_text = GeneratePythonScript(ws, StartTimestamp=str(from_time))
print(script_text.strip())

Example - generate a python script and save it to file:
import os
#create a workspace and run some operations on it
ws = CreateSampleWorkspace()
ws = CropWorkspace(ws, XMin=7828.162291, XMax=11980.906921)
ws = Power(ws, Exponent=1.5)
ws = RenameWorkspace(ws, OutputWorkspace="MyTestWorkspace")
path = os.path.join(os.path.expanduser("~"), 'myscript.py')
GeneratePythonScript(ws, Filename=path)
with open (path, 'r') as script:
print(script.read().strip())
