I like Application Error Log a lot, both for its full stack and a big list of variables. I'd like to "hack" this functionality and record the same in this log when a certain variable has a certain value. This quasi error should not be visible to the user, and it should not interrupt the application flow. Is that possible?

Throwing an error in a try-catch block does not record the error, tested. I am considering recording variables and the stack differently, I know how to do both, but that would miss the nice Application Error Log functionality.

Let's suppose two different routines use one and the same chunk of code. From the object-oriented POV, a good decision is to have this chunk of code in a separate class and have both routines call it. However, whenever you call code outside of the routine as opposed to calling code in the same routine, some execution speed is lost. For reports churning through millions of transactions this lost speed might be noticeable. Any advice how to optimize specifically speed?

  1. I like the Application Error Log functionality a lot. However, it becomes time consuming to inspect it date by date and directory by directory on a multidirectory server. Ideally, I would use an existing error class to write a custom error report by date, selected namespaces, etc. Does such a system class actually exist? Not that I found. The detail level on the screenshot below is enough.

I ask ChatGPT periodically to produce ObjectScript or plain MUMPS code for string manipulation, or for implementing known algorithms etc. Occasionally, it does make mistakes or uses non-existing class members but generally not that bad. Is there any tutorial on the subject of using AI for coding, ideally specifically for ObjectScript/MUMPS? Any AI productivity advice, or tricks you are using, or another AI flavor?

Thanks in advance,
Anna

The task is to find all globals that are referenced in certain routines. I could search for ^ using class(%Studio.Project).FindInFiles but that would also find ^ in comments and function calls. I can distinguish between a global and a function call visually, but it would be lovely to be able to skip function calls programmatically. Is it possible?

Access to current line text

Is there a general way to set a variable XYZ equal to the text of the code line being executed now? Debugger or production. For example, for a code below if code is currently assigning a to 1, XYZ would be equal "S a=1". The same question about a variable containing current routine name.

S a=1

As I was trying to create a routine search query via RoutineList, I discovered that documentation both for Cache and Iris offers only ABC* and ABC? syntax for including routine names and, unlike %RO, does not offer name ranges. Is that indeed so?

After some system files reading, I discovered that you can EXCLUDE certain routines with ', by using the 'ABC or 'ABC* syntax. That is not documented but it should be. Any other non-documented RoutineList syntax capabilities?

Example:

I have a few routines in ^rINDEX that are missing in ^ROUTINE. At least some of those routines lack a timestamp, probably Date and Time Modified in ^rINDEX. It causes D %RO crash when such a routine is referenced by a routine range, since "" is an illegal $ZDTH value.

Healthy entry (note the timestamp): ^rINDEX("ABC,"INT") = $lb("2021-06-15 15:08:38.846885",) ;The second argument is sometimes present and sometimes not, likely the routine size.

Unhealthy entry (note an empty timestamp): ^rINDEX("DEF,"INT") = $lb("",21)

I am trying to locate a method that would allow me to differentiate between InterSystems preinstalled/system namespaces and "our own" namespaces. I am interested both in Cache and Iris answers if they are different. Yes, I can list what to disregard, like if not HSLIB or if not DOCBOOK but hoping for a more universal and elegant answer.

The task for a file on disk is to open it, find a keyword (unique) and then read the file line by line, starting with the line with this keyword, then find the next keyword (also unique) and read from that location etc. I would think ObjectScript classes should be able to do that, but the solution eludes me. I probably need to use FindAt to get a position, but ReadLine does not seem to have a position argument. Any advice?

The goal is to identify programmatically all SOURCE namespaces on a server to which the routines are mapped. In the example below from the Namespaces page in Management Portal the answer would be USER. But some other namespaces on the same server could be mapped to a different namespace or even mapped to itself.

I am inspecting our DB globals in order to reduce sizes of the worst offenders if possible. When I come to a large global, I am interested which of its nodes are the largest. Hence code below with unexpected different results. Any explanations why are results different?

Cache: Binary export output

I have an odd binary result exporting a specific routine via Studio, Export. Below is the beginning. The seemingly same routine in a different directory is exported fine, regular human readable code. Inspecting ^ROUTINE and ^rIndex did not give me any clues. Any insights?

Breaking a string into words

Is there any ObjectScript or a basic function that takes a string and separates it into words + punctuation/spaces array/list? Just not to reinvent the wheel. Say, process "It is a test, after all" into "It", space, "is", space, "a", space, "test", ", ", "after", space, "all". Or something to that effect.

Tracking %RCOPY and %RI

Let's supposed somebody updates routines via %RCOPY or %RI, the really old-style hardcore way which still works. Does that leave any log traces in Journaling or system globals, as of when exactly did it happen or what was the IP address of the machine changes came from? I am aware only of the Date Modified changes as seen when opening the file.

I am familiar with $TEXT which can get you any line in the current routine provided you know the offset. For example, $T(+1) will get you the first line of the current routine at the run time. In the same vein, how do I reference the current line number/offset at the run time? Something like $T(+$CURRENTLINENUMBER) where $CURRENTLINENUMBER is not yet known to me function. The sample below would write 3 as the line number.

RTNNAME
S A=1
W $CURRENTLINENUMBER

Is there an ObjectScript analog of Find with Match Element Type option? I know there is an ObjectScript analog of Find in Files, Studio.Project.FindInFiles and Studio.Project.FindInProject, but I failed to locate so far an analog of Edit/Find. I am specifically interested in Match Element Type option so I could search across selected files for globals. Somehow Studio.Project.FindInFiles does not offer this option natively.

My objective is to find routine's Date/Time Saved someplace inside Cache. The routine's Date/Time Modified as returned by various queries like %Library.RoutineIndex and as seen on the File Open screen is actually Date/Time Compiled last, not Date/Time Saved last. Does anyone know if Date/Time Saved is created when the Save icon is pressed or the routine is imported? Such a timestamp should be immune to subsequent compilations with no changes.
