Today's "farming" is more technological every day.

Prepending '(*LIMIT_RECURSION=5)' to the regex pattern fixes the issue. Use 5, or 10 or 8. I didn't try to find the range of useable values. From the PCRE(v1) doc, underlined part is key: Setting match and recursion limits The caller of pcre_exec() can set a limit on the number of times the internal match() function is called and on the maximum depth of recursive calls. These facilities are provided to catch runaway matches that are provoked by patterns with huge matching trees (a typical example is a pattern with nested unlimited repeats) and to avoid running out of system stack by too much recursion. When one of these limits is reached, pcre_exec() gives an error return. The limits can also be set by items at the start of the pattern of the form (*LIMIT_MATCH=d) (*LIMIT_RECURSION=d) where d is any number of decimal digits. However, the value of the setting must be less than the value set (or defaulted) by the caller of pcre_exec() for it to have any effect. In other words, the pattern writer can lower the limits set by the programmer, but not raise them. If there is more than one setting of one of these limits, the lower value is used. Also note that the issues reveals only on pathalogicaly wrong patterns: ; string preparation Local $sString = 'E:\Windows\Performance\WinSAT\DataStore\' For $iCounter = 1 To 65537 $sString &= 'x' Next

[3] => String(55) '2020-02-11 06.58.56.166 Cpu.Assessment (Initial).WinSAT' [4] => String(4) '.xml' From what I understand, the pattern relies on finding at least one forward- or backward-slash or else falls into near-infinite backtraking when the input string is long enough. Short strings don't create such dramatically huge matching tree to backtrak into, so succeed or fail quickly.

Try using Word, LibreOffice or equivalent to create a document containing "some text" <style Horizontal line> "some text and save as .RTF. This should give you an idea on how this translates into RTF.

Yes, be sure to select PCRE engine (top right). Also RegExp is pretty good too. @OP: You can use '.+?/(\w+-\w+)' as well.

What @Nine said, but beware of this: Not that easy. Windows uses UTF16-LE internally, which means that a "character" (here I mean actually "one Unicode codepoint") can use either one or two 16-bit words. in RAM. Also, don't forget that AutoIt uses a subset of UTF16-LE named UCS-2, allowing full use of the Unicode BMP (Basic Multilingual Plane), i.e. codepoints U+0000 to U+FFFF. Hence, counting "characters" is not trivial. Common "characters" in non-english languages like à, Ê, ù, ç, ñ, ... can be represented using different normalization forms, see https://en.wikipedia.org/wiki/Unicode_equivalence#Normalization Moretheless what we, humans, mean by "character" may require more than one Unicode codepoint. This is the difference between glyph (what is displayed by the font renderer) and codepoint (the actual Unicode content). For instance this string $s = ChrW(0xD83D) & ChrW(0xDC68) & ChrW(0xD83C) & ChrW(0xDFFB) & ChrW(0x200D) & ChrW(0xD83D) & ChrW(0xDC69) & ChrW(0xD83C) & ChrW(0xDFFF) & ChrW(0x200D) & ChrW(0xD83D) & ChrW(0xDC66) & ChrW(0xD83C) & ChrW(0xDFFD) displays as in a Unicode-aware environment. And that is only speaking of valid representations: one may find out-of-spec representations in input strings, spanning representation of what we perceive as a "character" over an unbounded string of Unicode codepoints.

As others have said, you can use SQLite to perform such task. Since both files are .CSV, you don't even have to write code at all: use the SQLite command-line tool to load each .CSV in its own table and perform the comparison. Something like: SELECT GA_CODEARTICLE1, GA_DESIGNATION1, GA_CODEDIM1 FROM <SMALLER FILE> INTERSECT SELECT GA_CODEARTICLE1, GA_DESIGNATION1, GA_CODEDIM1 FROM <LARGER FILE> It woiuld greatly help to create on index on those 3 column on each table before launching the comparison. Various CLI options let you work with memory- or disk-based DBs. You can as well obtain the output in .CSV in other format (e.g. HTML, JSON, ...).

IIRC the 16M limit is just an order of magnitude; the actual limit significantly depends on the volume of data.

Import in SQLite and apply any SQL magic massage needed to your data. You can just use the SQLite CLI (the command-line interface) with a memory (default) or disc-based database. You can define row and column separators if needed, .import the file as --csv, apply SQL to filter out unwanted rows, rewrite the resultant table to csv or whatever format you wish. If this operation turns to routine, store all these commands in a file and run it with the CLI. Use a recent sqlite3.exe, it's now full of rich features. Else slap a good regex in the face of the file!

You can remove the /gm options: nothing changes.

@pixelsearch is correct in pointing out that behavior. I don't have access to the C++ source for these functions, but notice that while SRE uses published PCRE v1 API, the "Replace" part in SRER is homebrew since there is no "replace" support API in PCRE v1. Yet AutoIt implementation of SRER matches legacy behavior of other PCRE v1 libraries. Play with this example, using Match or Substitute, $0 or $1: https://regex101.com/r/URSZPk/1

Correct, but I meant that ALL (100%) of GUI components use UTF16-LE internally. BTW, AutoIt is somehow limited to UCS2.

@lkjojfgfdg Windows has been natively supporting UTF16 since late XP.

Warning that subst-ed drives may point to non-root, soft and hard links as well.

Then I'd have said: "... for the rest of the day". 71 now, but I still can count for some time!

@pixelsearch you're right on 2) About 1) and (*X), that PCRE_EXTRA option is something you can ever use only after digging deep in PCRE code, only helpful in very VERY dark corner cases you should avoid at any rate. Hence # should be removed from the list in help. Omitting ) is a much bigger mistake, one which will haunt me for the rest of the year! BTW, I whish a peaceful 2026 to everyone in and, most importantly, outside the AutoIt community.
