renumbering/incremental

Probably a lot faster to do this in excel by dragging down column to renumber and if needed use excels macros.

One sentence, so many things wrong with it…

[Phil Colbert]

Writing here as a former N/C Systems programmer.

1. Renumbering is usually easiest if you simply remove all the line numbers, completely, and generate a new set from scratch.

Fortunately, this is not like BASIC programs, where the numbers were referenced (GOTO, GOSUB) from other lines. (Some CNC controllers did allow that, but I never saw it used very much in actual CNC programs.)

If such references do exist, then you’d need to track down the references, and update them, too, to match. This requires good recordkeeping, and is definitely a candidate for automation.

If I recall correctly, some users would number only a selected few lines, e.g., those where a tool change occurred, or those beginning a subroutine or loop. The rest would remain unnumbered. On the other hand, if the machine found a syntax or other error, then tracking it down, without line numbers, became a major pain. There were, then, sometimes, two versions of a program: one with line numbers, used for early runs, and one without, used after the fully-numbered version had been proven reliable.

BASIC programs were often numbered in increments of 10, to allow for easy insertion of lines, without having to renumber the whole darn program. If you want to number every line, then I suggest doing the same thing here.

2. Doing it for thousands of distinct program files will require two distinct automations: one to locate and enumerate all the CNC files to be changed, wherever they are in the file system, and another to renumber each one.

I recommend putting the new, renumbered versions in a new location entirely, to avoid accidentally overwriting the original files. After all, programs rarely work right the first time!

Under Windows 10, CMD.EXE’s batch language can probably handle this kind of work. The advantage being that you don’t need to install it; it’s already there. The disadvantage being that it is a horrible programming language for newbies. (And just about everyone else.)

Having several years of experience, now, with Python, I can confidently say that Python is a much better bet for writing programs that novices can actually read, understand, and update. No add-on modules are required. Moreover, for tasks like this, very little of the Python language needs to be understood, to do an adequate job.

Python is available, free, in the Windows Store, so it is virtually painless to install. And Notepad++ is an excellent editor for writing your Python programs.

The sheer volume of work to be done makes it hard for me to recommend Notepad++ – or any manually-operated editor – in any other capacity, for this particular task.

@Alan-Kilborn Yes, that is what I was saying could be a wrinkle. However having been up since 2am, I am realizing that having to insert lines in between is an exception to the rule, rather than the rule.

That being said, I ran that script and it worked perfectly. I am going to study (I mean its only 3 lines, but still) that script and try to understand what each part means so maybe I can go forward and make changes on my own. Really my end goal with everything is to be able to learn, so I really appreciate all of the help youve given me to get here.

The only thing I dont see, is how to run that script on ALL of the files in the workspace. When I do a find/replace, you can run it on all files open in the workspace (which I will do when I get to the point that you previously helped me with (replacing by line # within program), but I am sure that is somewhere in the python help guides!

Thank you again and I will let you know my progress and what I have learned (I know, you are waiting with bated breath)

[Scott Raskin]

@Alan-Kilborn and then I am going to do some more research on seeing if I can combine the two things you helped me with into one script (the replacing specific line thing: \A(?-s).\R.\R.*\R)
Every time I start looking for the ability to use the script to replace EVERY file in a folders info, someone comes and interrupts me (and with my ADD I have to start all over again) How do you guys do this as I am assuming you are helping dozens of people on top of your regular life?

Hah, well, occupational hazard I guess.
Work-from-home helps. :-)
But yea, sometimes I wish the “real world” would go away, so I could sit around and play with Notepad++ all day. :-)

[Scott Raskin 0]

@Alan-Kilborn yeah, can’t work from home unfortunately as production of a physical product is a bit difficult remotely (until we have fully automated robots to do it all)
So, before I exhaust myself looking for naught, are either of those things possible (running the script on all of the files loaded in the workspace) and/or adding that line renumbered thing to the python code? If so. I will spend my weekend on the hunt

[Alan Kilborn]

@Scott-Raskin-0 said in renumbering/incremental:

Yes and yes, both are possible.
But…I think you started out talking about 1000 files…surely you aren’t going to have that many “loaded in the workspace” of Notepad++??

I think you’ve put in some hard work on this solution; how about if I finish up the script for you and post it? We sort of need such a model for the next time someone asks for this frequent need. We already have a template for a similar task that I can modify…

[Scott Raskin 0]

@Alan-Kilborn so what I did was click load folder into workspace and loaded that folder. I think there were close to 1000 files on the tree on the left. So, if I right click on the folder and do a find/replace and then click replace in all, it will replace in all 1000 files there. As for posting the code that would be amazing (as I’ve already seen a few people with my specific problem, and I imagine others with something similar)

OK, I understand your thinking on this now. Unfortunately, there’s no easy way to hook a script with custom-replace functionality into that action. But never fear, what I have in mind will work, albeit a bit differently.

Yes, give me a bit of time to do it and post it. Although it is 4am where I am (and I’ve just arisen after my 5 hours of sleep), I have a few other tasks to get to as well. Check back here periodically…

[Scott Raskin 0]

@Alan-Kilborn not a problem. You’re doing us all a favor, and thr time it will save me will be way more than the time between now and you posting it so we are all very appreciative. Also I’m in NY so I think we are on the same time zone, and as you can see by when I posted that. We both need to sleep more

[Alan Kilborn]

Under construction, please come back soon. :-(

Edit:

I posted the script, then I wanted to add some comments about it, so I edited it, but the site told me my post was “too long”, so I chopped off the first part (containing the script), thinking that when I submitted, what I submitted would be an additional posting. Doh! It just replaced the original (of course, like it is supposed to do).

So please wait while I reconstruct the two postings. I saved the second one, so no loss there; the first one I have the script listing , of course, but I lost the surrounding data there. :-(

[Scott Raskin]

@Alan-Kilborn nothing to be frowny-faced about. Will appreciate it as much next Monday as I would have today

[Alan Kilborn]

@Scott-Raskin

So the script listing follows. Before you think, from the length of it, that it was (a) a lot of work for me, or (b) that it is very complicated, well, it really was/is neither. The base algorithm is minimal, and I basically recycled ANOTHER SCRIPT for most of the logic.

Here’s the script listing for what I call ReplaceInFilesUsingCustomReplacementFunction.py (wow, sorry for long name!); after the listing are some details about running it:

To reiterate from an earlier post in this thread, information about setting up and running a PythonScript is in the FAQ, HERE.

So how do you run it, specifically for this application?

Open into Notepad++ a data file in the top-level folder where you want to do the replacements. Execute the script from the PythonScript menu in Notepad++. You’ll be asked some questions, and then the core replacement logic will run to make your changes.

[Alan Kilborn]

The script does what I think was what was wanted; it renumbers into order, with gaps in the numbering, all the Nx fields that occur at start-of-line, where “x” is some number of digits – and the important part: it does this across some folder hierarchy of possibly a large number of files.

If someone wanted to keep the core logic, but change the specific search and replacement, here’s what someone would do:

Search the code for the text USER MODS; you’d find some sections that look like this:

# vvvvvvvvvv---------- USER MODS REQUIRED BELOW ----------vvvvvvvvvv
# ^^^^^^^^^^---------- USER MODS REQUIRED ABOVE ----------^^^^^^^^^^

In between those lines are what you’d change for customization.

In the first case, you’d change what is being looked for, e.g.:

self.search_regex = r'^N\d+'  # search for N followed by some number of digits (but must be at start-of-line)

Change what is between the ' characters for the regular expression you’ve tested independent of the script.

In the second case, you’d find this:

def return_replacement_text_func(m):
    ....

and that’s where you’d put the replacement function you developed for the one file case.

For our scenario under discussion in this thread, that function looks like this:

def return_replacement_text_func(m):
    # replace with N and a minimum of 2 digits, e.g. N01, N90, N300
    repl_text = 'N{0:02}'.format(renumbering[CURRENT])      
    renumbering[CURRENT] += renumbering[INCREMENT]
    return repl_text

However, for this scenario, we need to remember some things between runs of this function – e.g., what’s our current count value – so we have some code that appears just above the definition of return_replacement_text_func, to allow that “memory” to happen:

renumbering = [ 1, 1 ]  # default to re-numbering starting with 1 and incrementing by 1; in the general case
CURRENT = 0; INCREMENT = 1  # indexes into the re-numbering list
renumbering[INCREMENT] = 10  # override our default increment-by and change it to 10, for our specific need

The replacement will do the first replacement using the text N01, the second with N11, third with N21, and so on.

Now, this all may seem very complicated if you were trying to write it from nothing, but maybe it isn’t so bad to read and follow the logic, or adapt to similar need.

@Alan-Kilborn This looks great and I will be doing some testing on it today. First thing I noticed was I needed to change this line: renumbering = [ 1, 1 ] to renumbering = [ 10, 1 ], as it has to start at 10 (or more, but I figured 10 was a good # to use, as if you remember from my other post, I need to edit some lines. So I really appreciate you making it easy, as that was very simple to find and edit. The next part I need to figure out is, where to have it do this (or do I justdo it separately. Its only 2 operations if I need to do separately and it will change 10k files so its worth it either way. The other post I had done we came up with

replace: \A(?-s).\R.\R.\R.\R.\R.\R.*\R
with : O0001 ;N01 ;N02 ;N03 ;N04 G94 G53 G56 T0000 ;N05 G92 X0.6820 Z2.1505 ;N06 G59 ;

So right now, If I run your script, followed by that search/replace it seems it does all I need to do. Just wondering if that is something python allows.

This is all amazing, and even with you being modest, you still put a good deal of effort into this and it is much appreciated

[Scott Raskin]

@Alan-Kilborn Sorry for breaking this into two messages: I also see where you have the self.search_regex and def retuen_replacement_text_func(m) I would be l;looking to make any future code modifications, so I can probably try adding that \A(?-s).\R.\R.\R.\R.\R.\R.*\R into the first part and the replacement into the second I just dont want to screw up the code. I will be back at the factory in a few hours to see.
Thanks again

@Scott-Raskin said in renumbering/incremental:

You could change it the way you state, but I’d suggest this as cleaner:

renumbering[CURRENT] = 10

inserted above this line in the script:

renumbering[INCREMENT] = 10

The “current” value is the starting value, and also the “running” value as the replacement moves along (that’s why I didn’t want to call it “starting”). Expressing one’s self in code isn’t always straightforward.

The “increment” value is well-named, but the fact that the INCREMENT tag in the code is 1 and NEVER should be changed, well, this does seem odd (it is used for a different purpose than one might think). Expressing one’s self in code isn’t always straightforward.

If you just think in terms of:

• if I want to change the starting value, I need to set renumbering[CURRENT] = something

• if I want to change the incrementing value, I need to set renumbering[INCREMENT] = something

and forget about the rest…for this specific application.

Not a problem. Part of the goal was somewhat of a generic solution (as you’ve probably noticed), so that the next time a question like this comes up (and it will), there is a model of a solution for it.

The script is rather dedicated to its renumbering/incrementing purpose, but it is just code so you could change it to go beyond that.

As the search/replace op you mention is just a normal one (no special math/renumber/increment stuff), you could just include an editor.rereplace(search,replace) function call right after this line:

replacements_made_in_this_file = self.perform_custom_replace_in_one_file(first_time_thru)

Note however that this would invalidate the script’s results reporting (at completion, telling you number of replacements made, etc.). Not a big deal if you trust the script, mainly I put that stuff in to be general purpose, and to give a user a sanity check if they know about how many files should be matched via filespec/filter, about how many replaces should have been done, etc.

If I were you, I’d keep it as two separate and distinct operations, running of a script, and then a follow-up Replace in Files op.

@Alan-Kilborn tried this
self.print(‘making replacements in’, pathname)
replacements_made_in_this_file = self.perform_custom_replace_in_one_file(first_time_thru)
editor.rereplace(\A(?-s).\R.&\R.\R.\R.\R.\R.\R.*\R,O0001 ;N0001 ;N0002 ;N0003 ;N0005 G94 G53 G56 T0000 ;N0010 G92 X0.6820 Z2.1505 ;
) self.print(‘{} replacements made in current file’.format(replacements_made_in_this_file))

and the script wont even run now. Maybe youre right and 2 ops is the best

[Scott Raskin]

@Alan-Kilborn copy/paste made it look weird for some reason in the post but that search/replace was all one line in the script
