Changes:
Adding support to break long regex strings for Jamf Pro.
Modified: May 24, 2020
Changes:
Displaying sequence characters in verbose reporting instead of number.
Now accounting for version strings with non-numeric characters.
Added warning if sequence begins with "0".
Added warning if sequence contains non-standard characters.
Accounting for multple Jamf Pro regex strings.
Purpose: Generate a regular expression (regex) string that matches
the provided version number or higher.
Instructions: Run the script in Terminal, supplying a version number
string as the first argument:
e.g. '/path/to/Match Version Number or Higher.bash' 16.17
Or run the script in Terminal without any argument to use the example
version number string within the script.
Optionally, set verbose to "On" or "Off".

Hi @talkingmoose, many thanks for this script. I've been thinking about how it could be used as part of an automation workflow, since the regex is only good for whatever the current version is, so needs to change every time there is an update.

I'd love to try and incorporate this into an AutoPkg. It would be simple enough to make a Processor that called the script via a subprocess command. It's the output of the current script that is problematic. Have you considered a parameter or option to output either just the regex without additional info strings, or output to JSON or a Plist so that the relevant value can be easily extracted?

@grahampugh, I can certainly include something like this for munki.

Let's think about the right approach. Right now, I have a couple of variables that require toggling within the script to make it behave differently. I can add another toggle for "regex only". Would it be wise to convert all of these to options that can be called as part of the command? Something like -J | --jamf-output, and -V | --verbose-output?

I'd then make "regex only " the default behavior without any options.

Or does it satisfy a need to keep these as variables in the script itself? I'm leaning toward the first idea.

@grahampugh

@talkingmoose something long those lines seems perfect. I don't mean to change the default behaviour that you envisaged (unless you want to!), but a flag such as -r | --regex-only or -q | quiet which outputted only the regex would make sense. I'm not sure if --jamf-output is an appropriate name, since the regex-only output could be used in any system.

I would personally either create a new AutoPkg processor to run the script and provide the regex as an output variable for subsequent processors (e.g. JSSImporter), or possibly incorporate the functionality directly into JSSImporter (I can do that, since I'm the maintainer) so that existing .jss recipes could be used. Only the SmartGroupTemplate.xml would need to be changed to incorporate the regex.

@grahampugh Currently Jamf Pro cannot handle a regex expression longer than 255 characters, and some version strings result in a regex longer than that, so the Jamf mode was created to split the output in multiple shorter regexen

@grahampugh

@sdagley Ah, I see what you mean. That would be tricky (but essential) to somehow incorporate into the automation. Perhaps it could be done separately in the processor though. Or hopefully Jamf will lengthen the acceptable number of characters. @talkingmoose is that worth an FR?

@grahampugh I opened PI-008150 for the 255 character regex limit, but I just checked the Jamf Pro Known Issues page and it's not listed (nor does searching on "regex" have any hits). Hopefully @talkingmoose can determine the status of that PI.

@grahampugh I asked Jamf support for a status on PI-008150, and they replied that they're still waiting for a response from engineering. Since it was reported 2 months ago you might try adding your voice as being impacted to see if generates any extra traction.

Hi @talkingmoose, a colleague has come across an edge case where the following line (312) is being scuppered by the presence of an actual b in the version string:

		dividedRegex=$( /usr/bin/sed "s/|/b/$breakDelimiterPosition" <<< "$dividedRegex" )

I'm curious as to (1) why the | needs to be substituted at all, and (2) if there is a specific reason for choosing b as the replacement string that I'm not seeing? I'm thinking of replacing it with a little-used character such as § or ±.

Hi @grahampugh! It's been a while since I've revisited this gist, but I believe the sed substitution was a response to having to break long regex strings into smaller strings when used with Jamf Pro. Its fields had a limit of around 250 characters, and long version strings like Google's needed a solution. I probably used "b" for "break here at this 'or' statement".

You're right that most any character (or short string) here would work. You'll also need to adjust the awk field delimiter on line 334 to use the same character or short string.

In the interest of not having to deal with breaking a >255 character pattern into smaller versions I've adopted Cameron Moore's make_ge_version_regexp.sh fork of this script (https://github.com/moorereason/make_ge_version_regex) which generates much shorter patterns. While the README for it refers to the optimized patterns generated as being Jamf-unsafe I have not run into an instance where they haven't worked.

@talkingmoose thanks, I've gone ahead and switched out the b for a ± in my version of the script and it seems to be doing the trick.

I'm no longer maintaining a Jamf instance, so feel free to take my optimizations and run with them.

P.S. - My version generates a 167 character pattern for that version string versus the 291 character pattern from Will's script. 😉 However, I will say I'm super-impressed by Will's script and thoroughly enjoyed dissecting it to understand how it worked and how I might could improve it. 👏

P.P.S. - I forgot about this whole project and didn't know if anyone even knew it was out there, so thanks for making my day, @sdagley!
