Write all Add Messages to text file

NealBanerjee — Sat, 02 Jan 2021 14:49:14 GMT

Hello,

I have a script tool that I use 'Add Message' to indicate progress during tool execution. I would like to also write everything that I am writing to a text/log file. I know I can do this manually by use a separate standard Python logfile.write process, but wanted to see if anyway to either capture messages at one time

Thanks!

Neal

GetMessages—ArcGIS Pro | Documentation

If it was wrapped up into a single tool execution I guess, otherwise it's a case of logging each add Message to a list.

Thanks David, in my case it is a number of messages that want to capture.

Can you wrap the script into a function, then grab all the messages in a single call after it's been executed ?(unsure myself - the method could be better elaborated on in the help).

msg = "start\n" stuff msg += "did something\n" stuff msg += "did more something\n" stuff msg += "done\n" with open(r"c:\somefolder\Output.txt", "w") as text_file: text_file.write(msg)

usually works

Thank you Dan and David for your help. What I ended up doing is I think along the lines of what you both mentioned, but maybe a little different. I first created a very simple mini-function in my main script that takes a string parameter. The function then uses 'AddMessage' to return the message to user running script tool and the logfile.write to write same message to a separate text log file. Below is function I created and a snippet of code showing how I used it. Maybe not the most elaborate, but better than having to write each message basically twice.

def WriteMsg(strMsg): arcpy.AddMessage(strMsg) logfile.write(strMsg + "\n") return ### Simple snippet below lstdomains = arcpy.da.ListDomains(inFGDB) #Get list of domains in inFGDB addmsg="Processing domains in input workspace: {0} and writing as tables in: {1}".format(inFGDB, outFGDB) WriteMsg(addmsg)
