Two 60MB updates in a week and it's nagging me while I'm trying to code. Can't you do rollouts on a monthly schedule or something?
Grr. Microsoft schleps updates at people like they are something they *want*.
Get your #*@( elephant together and establish regular ship dates.

I guess the saying "If it's free, you're the product" needs to be revised to include the possibility of you being the guinea pig.
"Elephant" wasn't necessary when $#!+ would've done nicely.

I mean otherwise I love it. It's one of the best things they ever produced. But just keep to a schedule!

I am not so certain that is a good idea. The last update of Visual Studio was the worst I have ever received and I still haven't restored full functionality after it. That hosed things up pretty well for me and I refuse to update my other machines since I still have work to do. Hopefully Code has better success with that.

So what you're saying that you would like the VS Code updates to be socially distanced?

This sounds like a lot of release cycles:
"We have to release features X/1.0, X/1.1, X/1.2, and X/1.4 immediately!"
"What about X/1.3?"
"It's not passed the Pink Sheep 1.7 suite of tests yet. It absolutely can't be released."
"Ooookaaayyyy..."
24 hours pass, and the app is distributed to $117M worth of customers.
"Oh ![Elephant | [mastadon]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/elephant.gif) !"
"WHAT?"
"We just figured out that X/1.4 requires one of the changes in X/1.3 and we didn't release them together."
"So, that just means that X/1.4 doesn't work."
"Yeah, but the default behavior on X/1.4 failure is to re-init the customer's data base back to W/0.7 levels. Everything they've done over the last 18 months is lost."
"We are truly ed..."

What time (in UTC for easy calculations, please)?

Actually, that would only be true if the cat they dropped down the hole, first, is named doppler.
Whatever it's name, however, it will still make the same noise when hit by a hunk of ice.

I needed a way to compare an escaped string coming out of a file with a series of unescaped strings passed to a function to see if one of them matches.
The easy way:
Load the string from the file, unescape it and compare each string in turn.
Pro: easy to code and maintain
Con: Requires the entire string to live in memory, requiring a buffer for it first.
The hard way:
Load the string one character at a time from a file, while deescaping inline, keep a list of pointers to the current location for each string you're checking against, compare and advance each of the string pointers in turn. If one doesn't match, disqualify it by setting its pointer to null, and when you're done see if you wound up with an undisqualified string.
Pro: only needs a character at a time in memory, plus scratch for the pointers
Con: Weird to write and maintain.
Because I'm coding on extremely low memory scenarios, i picked the hard way. I hate this code though, but there is an irresponsible part of me that enjoyed writing it.

Is it a fixed or dynamic list of strings to check.
If it is fixed, us your lex/parser-fu and create a DFA/lexer to check for the strings.
DFAs are very memory efficient, as you know.

The strings are determined at runtime so building a DFA is not desirable.
Edit: It might be possible to pre-bake DFAs for predefined queries but that would be more of a code generation thing. The thing is I don't have the RAM for DFA tables so I'd need it to be compiled.

How about creating a tree from the list of strings characters. Then you could attempt to traverse the tree as the characters come in and if you get to a leaf, you have a match. If you would need to buffer a bit so you can backtrack, but I think you know how to do this.

The biggest concern is RAM. Speed is secondary. I need to use as few bytes as possible for this. The strings are already allocated because 99% of the time the passed in strings are constant so i don't waste bytes reallocating them in a different form. I suppose I could turn the list of strings i'm using into a tree but there are fewer than 5 strings for the average query. Usually one or two, maybe three.

I have a slight suspicion that this 'minimal RAM' has become an obsession with you. I have been working with embedded processors for 10+ year, and seen how available resources have grown for off-the-shelf embedded chips. 10+ years ago, IoT was not a concept, but those chips (or rather: their successors) I worked with ten years ago are those used in IoT things today. Today they are capable, low power, modern.
If you look upon yourself as a masochist, you may of course go for something like a 2903 four-bit bit slice processor (really intended for combining 4 or 8 to a 16- or 32-bit CPU), where you have to write the microcode yourself. If you are not quite as much a die-hard masochist, you may go for an 8-bit CPU with 16 bits memory bus, but only 4096 bytes allocated to RAM.
That is for masochists only. Not The Way to solve a problem, create a solution. If you really need to implement an IoT solution, there are numerous processor alternatives giving you access to lots of resources way beyond what your are talking about.
Your attitude reminds me of the very first international conference I ever visited, on free text search, where one paper showed how they had succeeded in reducing the space requirement for index terms by (slightly less than) one bit per index term. Maybe the technology was great that year, but I have never heard of them later.
For being blunt: Anno 2020, no solution will earn everlasting accolade because it fit in 4K RAM. Not even 16K RAM. If you move up to 64K (or more), that is what everybody is doing. Nothing special about that.
'I managed to fit it into 4K!' is a battle arena left long ago. Sure: Some groups have developed it into an extreme art - you will find a huge collection at pouët.net[^]. One of my favorites is Skyline[^] - do download it to see what they managed to squeeze into 4096 bytes - it it totally unbelievable!
But that is not 'problem solving', not 'usable' in any way. It is just show off: Ain't I clever? Yes, you are, and impressively so.
Now, let us go back to productive world. Let us solve real world problems of today, using tools of today.
