M:
I’m building a site that displays ChatGPT conversations. Each conversation is stored as a single .php file which will later be read by a PHP wrapper that handles all visual structure.
Right now I have: • One file per conversation, already: 1. Exported from ChatGPT 2. Split into Markdown 3. Converted by Pandoc (gfm → html) into HTML
These Pandoc HTML files are too “thick” (divs, classes,
, etc). I want to compress each one to a minimal “Level 2” format that keeps only the data my wrapper needs.
⸻
TARGET FORMAT FOR EACH CONVO FILE
Each convo file will end up with: 1. A header comment block at the top, with tiny labeled lines 2. A series of tab-separated message lines, one line per message
Labels: • T: title • S: started • U: updated • C: message count • X: extra/export ID
These values already exist somewhere in the exported/Pandoc HTML; the regex pipeline should strip any HTML markup around them and reshape them into this comment block.
BLOCKID
Where: • BLOCKID = YYYYMMDDHHMMrNNN • YYYYMMDDHHMM comes from the
convo’s filename (e.g. 2025-06-09_1014 → 202506091014) • r is a single
lowercase letter indicating role: • m = me (user) • g = assistant
(ChatGPT) • later I may add something like e for error/system lines •
NNN is a 3-digit, zero-padded counter per convo: 001, 002, 003, … • TS =
the message’s own timestamp string, exactly as taken from the Pandoc
HTML (the [2025-06-09 10:14] style bit). • HTML = the body of the
message, still in HTML, with all inner formatting preserved (,
, , etc.). Only the outer scaffolding (div wrappers, labels
like USER: / ASSISTANT:, etc.) should be removed.
Examples of target lines:
202506091014m001\t[2025-06-09 10:14]\tHello there.
This is a
test. 202506091014g002\t[2025-06-09 10:14]\tTLDR: Here
is the answer…
The PHP wrapper will later: • infer the role from the 13th character of BLOCKID (m or g), • use TS for display/metadata, • and wrap HTML in whatever presentation structure it wants.
⸻
WHAT I NEED FROM THIS SILO
I’ll provide: • One or more sample Pandoc HTML convo files (current state) • Confirmation of the filename pattern, e.g. YYYY-MM-DD_TTTT-whatever.php so you can see where YYYYMMDDHHMM comes from
I need this silo to help me design a sequence of regex search/replace steps that: 1. Take the Pandoc HTML: • with its
,
Constraints: • The pipeline is regex-based search/replace, applied in order (I already have a batch script that can run a list of regex replacements sequentially). • Regexes should be written with real-world robustness in mind: • multiline matches, • spacing variation, • greedy vs non-greedy, • and quirks of Pandoc’s HTML output. • I don’t need full scripts in here; I just need a clear, ordered list of regex patterns and replacements that will transform a sample Pandoc HTML convo into this Level 2 format.
G: [Non-text content: thoughts; content_type=thoughts]
G: [Non-text content: reasoning_recap; content_type=reasoning_recap]
G: Got it. I’ll give you a concrete, ordered pipeline and also be blunt about what can’t be done with regex alone (the NNN counter).
今回（こんかい）の 目標（もくひょう）は 正確（せいかく）な 手順（てじゅん）を 決めることです。 – This time the goal is to decide on precise steps.
sed/grep. You need either:
awk/nl pass at the end, orI’ll assume:
I’ll assume the (already Pandoc’d) convo HTML looks roughly like this:
Metadata block at top of
<body>:
<p><strong>Title:</strong> My Conversation Title</p>
<p><strong>Started:</strong> 2025-06-09 10:14</p>
<p><strong>Updated:</strong> 2025-06-09 11:02</p>
<p><strong>Messages:</strong> 42</p>
<p><strong>Export ID:</strong> abc123</p>Messages:
<div class="message">
<p><strong>User</strong> [2025-06-09 10:14]</p>
<p>Hello there.<br/>
This is a test.</p>
</div>
<div class="message">
<p><strong>Assistant</strong> [2025-06-09 10:14]</p>
<p><strong>TLDR:</strong> Here is the answer…</p>
</div>If your real structure is similar but not identical (e.g.
User: with a colon, or different class names), you’ll just
tweak those literal bits in the patterns.
From a filename like:
2025-06-09_1014-whatever.phpyou want BASEID = 202506091014.
Shell-only pre-step (outside regex pipeline):
f="2025-06-09_1014-whatever.php"
baseid="$(printf '%s%s\n' "${f:0:4}${f:5:2}${f:8:2}" "${f:11:4}")"
# => 202506091014
# Insert as a first line marker:
printf '__BASEID__%s__BASEID__\n' "$baseid" | cat - "$f" > "$f.tmp" && mv "$f.tmp" "$f"From here on, your regex pipeline can assume the first line is:
__BASEID__202506091014__BASEID__Pattern 3.1 – drop everything before
<body>
(?s).*?<body[^>]*>Replace with:
__BODY_START__(You could also replace with nothing, but a marker is nice while debugging.)
Pattern 3.2 – drop everything after
</body>
(?s)</body>.*$Replace with:
__BODY_END__After this, file looks like:
__BASEID__202506091014__BASEID__
__BODY_START__
<p><strong>Title:</strong> ... etc ...
...
</div>
__BODY_END__You can optionally remove __BODY_START__/__BODY_END__
later with a simple s/__BODY_START__\n?// and
s/\n?__BODY_END__//.
Assuming it’s exactly as in §1.
Pattern 4.1 – match the whole metadata block
(?s)<p><strong>Title:</strong>\s*(.*?)</p>\s*
<p><strong>Started:</strong>\s*(.*?)</p>\s*
<p><strong>Updated:</strong>\s*(.*?)</p>\s*
<p><strong>Messages:</strong>\s*(\d+)</p>\s*
<p><strong>Export ID:</strong>\s*(.*?)</p>Replace with:
<!--
T: \1
S: \2
U: \3
C: \4
X: \5
-->This gives you the header comment already in final format.
If the label text differs (Conversation title,
Exported:, etc.), change the literal words accordingly, but
keep the capture groups structure.
<div class="message">…</div> into a
bare logical message lineWe’ll do it in three sub-steps:
Pattern 5.1
(?s)<div class="message">\s*<p><strong>(User|Assistant)</strong>\s*(\[[^]]+\])</p>\s*(.*?)</div>User or Assistant[2025-06-09 10:14] (TS)<p>…</p>, lists, etc.)Replace with (intermediate markers):
__MSG__\1\t\2\t\3__ENDMSG__So a typical piece becomes a single big block of text with special markers around the HTML.
Now normalize User → m,
Assistant → g.
Pattern 5.2a
__MSG__User\tReplace with:
__MSG__m\tPattern 5.2b
__MSG__Assistant\tReplace with:
__MSG__g\tRight now you might still have newlines inside \3 from
Pandoc. If you truly need one physical line per
message, we need to encode those newlines.
One cheap, regex-only approach: within each
__MSG__…__ENDMSG__ block, replace newlines with
literal \n.
If your engine supports “find” and “replace in group” you can be fancy, but to keep it portable, do a rough global replacement after messages are extracted and before we strip the markers:
Pattern 5.3
__ENDMSG__Replace with (ensure there’s a real newline at the end):
__ENDMSG__\nThen globally:
Pattern 5.4
(?<!__MSG__m|\t)(\r?\n)…but that gets ugly because we’d have to carefully avoid header/comment. Realistically, this is where a tiny non-regex helper is saner. So instead:
awk pass to encode internal newlines.Since you explicitly said “one line per message”, here’s a simple
awk step you can drop in at the end (after
we’ve built block IDs), so I’ll postpone full newline-handling to §7.
For now, we just ensure each message ends with __ENDMSG__ +
newline (5.3), which is enough for the remainder of the regex
pipeline.
We now have (roughly):
<!-- header ... -->
__MSG__m [2025-06-09 10:14] <p>body...</p>__ENDMSG__
__MSG__g [2025-06-09 10:14] <p>body...</p>__ENDMSG__
...We also have the base timestamp line at the very top:
__BASEID__202506091014__BASEID__BASEID into a simple tokenPattern 6.1
^__BASEID__(\d{12})__BASEID__\s*Replace with:
__BASEID__\1So the very top becomes a single line:
__BASEID__202506091014We’ll temporarily use @@@ as the NNN placeholder.
Pattern 6.2
__MSG__(m|g)\t(\[[^]]+\])\t(.*?)__ENDMSG__Replace with:
__BLOCK__\1\t\2\t\3Now we have:
__BASEID__202506091014
__BLOCK__m [2025-06-09 10:14] <p>body...</p>
__BLOCK__g [2025-06-09 10:14] <p>body...</p>
...Now we turn each __BLOCK__r into something like:
BASEID r NNN<TAB>TS<TAB>HTMLBut we still don’t have the NNN part; we’ll slot a placeholder in for now.
Pattern 7.1
__BLOCK__(m|g)\t([^\t]+)\t(.*)Replace with:
__LINE__\1\t\2\t\3So:
__LINE__m [2025-06-09 10:14] <p>body...</p>Then we use BASEID:
Pattern 7.2
^__BASEID__(\d{12})$Replace with:
__BASESTAMP__\1Now we have:
__BASESTAMP__202506091014
__LINE__m [2025-06-09 10:14] <p>body...</p>
__LINE__g [2025-06-09 10:14] <p>body...</p>
...At this point, we’re ready for the non-regex finishing pass.
awk or nl pass to stamp NNN and splice
baseidHere’s a concrete awk one-liner that:
BASESTAMP,BLOCKID<TAB>TS<TAB>HTML
lines.awk '
/^__BASESTAMP__/ { base = substr($0, 14); next }
/^__LINE__/ {
role = substr($0, 9, 1); # m or g
rest = substr($0, 11); # everything after "__LINE__X\t"
count++;
nnn = sprintf("%03d", count);
# rest is: TS \t HTML
print base role nnn "\t" rest;
next
}
{ print } # pass through header comment as-is
' input.php > output.phpResulting message lines look like:
202506091014m001 [2025-06-09 10:14] <p>Hello there.<br/>This is a test.</p>
202506091014g002 [2025-06-09 10:14] <p><strong>TLDR:</strong> Here is the answer…</p>Which matches your Level 2 spec, except the HTML is still fully
<p>...</p>. If you want to strip the outer
<p>…</p> wrapper and keep only its inner
HTML:
Optional: strip outer <p> tags after all
the above, on each line
Pattern (strip a single wrapping
<p>…</p> if present at start of
HTML)
^([0-9]{12}[mg][0-9]{3}\t\[[^]]+\]\t)<p>(.*)</p>\s*$Replace with:
\1\2That keeps <strong>, <br/>,
<ul>, etc. but removes the extra paragraph
wrapper.
If your wrapper truly needs “no literal \n in the HTML
field”, add this awk tweak inside the previous
script:
Replace the line:
rest = substr($0, 11); # everything after "__LINE__X\t"with:
rest = substr($0, 11);
gsub(/\r/, "", rest);
gsub(/\n/, "\\n", rest); # encode newlines inside HTML as literal \nThen every physical line in the final file is exactly one message line.
Ignoring the optional whitespace tweaks and assuming PCRE-ish syntax:
Strip to body:
(?s).*?<body[^>]*> →
__BODY_START__(?s)</body>.*$ → __BODY_END__Metadata → header comment:
(?s)<p><strong>Title:</strong>\s*(.*?)</p>\s*<p><strong>Started:</strong>\s*(.*?)</p>\s*<p><strong>Updated:</strong>\s*(.*?)</p>\s*<p><strong>Messages:</strong>\s*(\d+)</p>\s*<p><strong>Export ID:</strong>\s*(.*?)</p><!--\nT: \1\nS: \2\nU: \3\nC: \4\nX: \5\n-->Messages:
(?s)<div class="message">\s*<p><strong>(User|Assistant)</strong>\s*(\[[^]]+\])</p>\s*(.*?)</div>__MSG__\1\t\2\t\3__ENDMSG____MSG__User\t → __MSG__m\t__MSG__Assistant\t → __MSG__g\tBase ID normalize:
^__BASEID__(\d{12})__BASEID__\s* →
__BASEID__\1^__BASEID__(\d{12})$ →
__BASESTAMP__\1Message marker → line marker:
(?s)__MSG__(m|g)\t(\[[^]]+\])\t(.*?)__ENDMSG____BLOCK__\1\t\2\t\3__BLOCK__(m|g)\t([^\t]+)\t(.*) →
__LINE__\1\t\2\t\3Optional outer <p> removal at the end:
^([0-9]{12}[mg][0-9]{3}\t\[[^]]+\]\t)<p>(.*)</p>\s*$\1\2Everything else (counting to NNN and literal newline handling) is
best done in the tiny awk pass.
正解（せいかい）が 一つ（ひとつ）でなくても かまいません。 – It’s
okay if there isn’t only one correct answer.
If/when you drop a real sample Pandoc HTML, we can tune these patterns
to match it exactly and cut out any unnecessary steps.
M: Assume regex alone will not handle the NNN numbering for BLOCKIDs; I’m fine with a separate, minimal pass that keeps a counter and inserts YYYYMMDDHHMMrNNN, but I want all other transformations done with sequential regex search/replaces. Seems like he might already have done that, but this is explicit permission in case that helps.
G: [Non-text content: thoughts; content_type=thoughts]
G: [Non-text content: reasoning_recap; content_type=reasoning_recap]
G: Cool, then we’re totally
aligned: everything except NNN will be pure regex, and
one tiny counter-pass will stamp
YYYYMMDDHHMMrNNN at the end.
この（この） 方針（ほうしん）で 問題（もんだい）は ありません。 – There’s no problem with this plan.
Below is a cleaned-up, two-phase design based on what I wrote before, now explicitly split:
Inputs:
YYYY-MM-DD_HHMM-whatever.phpOutputs (after Phase 1):
<!-- … -->__LINE__m\t[TS]\tHTML BODYYYYYMMDDHHMMrNNN yet; that’s Phase 2.I’ll keep this abstract because we still haven’t locked the exact Pandoc structure, but the shape is:
Outside your regex runner (e.g. in the script that loops files):
f="2025-06-09_1014-whatever.php"
baseid="${f:0:4}${f:5:2}${f:8:2}${f:11:4}" # 202506091014
printf '__BASEID__%s__BASEID__\n' "$baseid" | cat - "$f" > "$f.tmp" && mv "$f.tmp" "$f"Now first line in the file is:
__BASEID__202506091014__BASEID__From here on, everything is regex only until we get to Phase 2.
Drop everything before
<body>
(?s).*?<body[^>]*>→ replace with:
__BODY_START__Drop everything after
</body>
(?s)</body>.*$→ replace with:
__BODY_END__(You can later strip __BODY_START__ /
__BODY_END__ if you want.)
Assuming the Pandoc HTML has some consistent format like:
<p><strong>Title:</strong> Conversation Title</p>
<p><strong>Started:</strong> 2025-06-09 10:14</p>
<p><strong>Updated:</strong> 2025-06-09 11:02</p>
<p><strong>Messages:</strong> 42</p>
<p><strong>Export ID:</strong> abc123</p>Then:
(?s)<p><strong>Title:</strong>\s*(.*?)</p>\s*
<p><strong>Started:</strong>\s*(.*?)</p>\s*
<p><strong>Updated:</strong>\s*(.*?)</p>\s*
<p><strong>Messages:</strong>\s*(\d+)</p>\s*
<p><strong>Export ID:</strong>\s*(.*?)</p>Replace with:
<!--
T: \1
S: \2
U: \3
C: \4
X: \5
-->After this, all the metadata HTML is gone, replaced with exactly the header format you want.
<div> into a line-like markerAssuming a pattern like:
<div class="message">
<p><strong>User</strong> [2025-06-09 10:14]</p>
<p>Body HTML…</p>
</div>4.1 Capture role + timestamp + body
(?s)<div class="message">\s*<p><strong>(User|Assistant)</strong>\s*(\[[^]]+\])</p>\s*(.*?)</div>Replace with:
__MSG__\1\t\2\t\3__ENDMSG__Now each message is essentially one blob of text with your own markers.
4.2 Normalize role to m /
g
__MSG__User\t→ __MSG__m\t
__MSG__Assistant\t→ __MSG__g\t
We now have things like:
__MSG__m\t[2025-06-09 10:14]\t<p>body…</p>__ENDMSG__(Newlines can still exist inside the HTML; we’ll handle that later if needed.)
__LINE__
form5.1 Normalize BASEID
^__BASEID__(\d{12})__BASEID__\s*→ __BASESTAMP__\1
You now have:
__BASESTAMP__202506091014
<!-- header -->
__MSG__m\t[TS]\tHTML__ENDMSG__
...5.2 Convert __MSG__ →
__LINE__
First, get a cleaner marker:
(?s)__MSG__(m|g)\t(\[[^]]+\])\t(.*?)__ENDMSG__Replace with:
__LINE__\1\t\2\t\3So each message is now:
__LINE__m\t[2025-06-09 10:14]\t<p>body…</p>At this point:
__LINE__m/gYYYYMMDDHHMMrNNN.Optionally, if you want to remove a single outer
<p>…</p> around body later (after numbering),
keep this pattern handy:
^([0-9]{12}[mg][0-9]{3}\t\[[^]]+\]\t)<p>(.*)</p>\s*$→ \1\2
Now the file has a shape like:
__BASESTAMP__202506091014
<!--
T: ...
...
-->
__LINE__m [2025-06-09 10:14] <p>body…</p>
__LINE__g [2025-06-09 10:14] <p>body…</p>
...We want:
202506091014m001 [2025-06-09 10:14] <p>body…</p>
202506091014g002 [2025-06-09 10:14] <p>body…</p>
...Awk one-liner:
awk '
/^__BASESTAMP__/ { base = substr($0, 14); next }
/^__LINE__/ {
role = substr($0, 9, 1); # m or g
rest = substr($0, 11); # TS\tHTML
count++;
nnn = sprintf("%03d", count);
print base role nnn "\t" rest;
next
}
{ print } # pass header etc. through unchanged
' input.php > output.phpIf you later decide you need literal \n inside HTML
rather than actual newlines, we just add:
gsub(/\r/, "", rest);
gsub(/\n/, "\\n", rest);before the print.
Regex phase:
__LINE__r\tTS\tHTML.__BASESTAMP__YYYYMMDDHHMM marker at
top.Counter phase (tiny awk):
BLOCKID<TAB>TS<TAB>HTML.Once you drop a real sample Pandoc convo, we can swap in the exact labels/classes you’ve actually got, but the architecture above doesn’t need to change at all.
M: sorry - i was working with a phone that didn't have the file you were promised. here's an instance of what's being converted.
G: [Non-text content: thoughts; content_type=thoughts]
M: i realized i should give you more for comparison's sake. here are four from the same day; no idea what the content is at the moment, so this could be interesting or unhelpful. let me know if you need any other examples that would help you in analysis/answering.
G: [Non-text content: thoughts; content_type=thoughts]
G: [Non-text content: reasoning_recap; content_type=reasoning_recap]
G: Good, the samples help a lot — your exports are way cleaner than the generic Pandoc horror I had pre-imagined.

From a filename:
2025-06-16_0844.phpyou want:

Optional cleanliness step (if you want to remove totally empty paragraphs that were only the label):
5.3 – Drop blank <p>s
<p>\s*</p>→ (empty string)
Now a typical message body looks like:
<p>i'm enjoying the mobile game 'idle slayer', but...</p>or for multi-block answers:
<p>Here’s what I’ve pieced together…</p>
<hr />
<h3 id="..."> … </h3>
<p>...</p>
<ul>...</ul>All of that is still inside the __MSG__...__ENDMSG__
envelope.
__MSG__ blocks into __LINE__ rowsWe want an intermediate form:
__LINE__m\t2025-06-16 08:44:55 EDT\t<p>body…</p>...Pattern (DOTALL):
(?s)__MSG__(m|g)\t(.*?)\t(.*?)__ENDMSG__\1 = role letter m / g\2 = TS (timestamp string)\3 = the full HTML bodyReplacement:
__LINE__\1\t\2\t\3At this point the core of the file is:
__BASESTAMP__202506160844
<!--
T: ...
...
-->
__LINE__m\t2025-06-16 08:44:55 EDT\t<p>...</p>
__LINE__g\t2025-06-16 08:52:49 EDT\t<p>...</p><p>...</p>...
...That’s your Level-2 structure, minus the final BLOCKID, ready for the counter pass.
If you later want to strip a single outer
<p>...</p> wrapper from each body (keeping
<strong>, <ul>, etc.), do that
after the next phase, when BLOCKIDs exist, with the
pattern I’ll put at the end.
YYYYMMDDHHMMrNNN BLOCKIDsNow we do the only non-regex step: assign NNN and
build the full BLOCKID.
Desired final structure per message:
202506160844m001\t2025-06-16 08:44:55 EDT\t<p>...</p>
202506160844g002\t2025-06-16 08:52:49 EDT\t<p>...</p><p>...</p>...
...awk passawk '
/^__BASESTAMP__/ {
base = substr($0, 14); # characters after "__BASESTAMP__"
next
}
/^__LINE__/ {
role = substr($0, 9, 1); # the m/g after "__LINE__"
rest = substr($0, 11); # everything after "__LINE__x\t" => TS<TAB>HTML
count++;
nnn = sprintf("%03d", count);
print base role nnn "\t" rest;
next
}
{ print } # pass through header comment and anything else unchanged
' input.php > output.php__BASESTAMP__202506160844 is read once →
base.__LINE__:
count.001, 002, …BASE + role + NNN + TAB + TS + TAB + HTML.Now your file is in final Level-2 form:
__BASESTAMP__202506160844 <-- you can keep or strip this; it's redundant now

これ（これ）なら 後（あと）から 管理（かんり）しやすい 形式（けいしき）に なります。 – This way you end up with a format that’s easy to manage later.
If you want, next step I can do is: take one of these actual files, run this pipeline in the notebook, and show you before/after for a couple of messages so you can sanity-check the output shape against your wrapper’s expectations.
M: my script runs by taking pairs of lines and using them as the search and replace patterns, respectively. would you kindly give me the various search/replace pairs you're suggesting formatted that way?
G: Understood.
Below is exactly what you asked for:
pairs of lines, each pair = search
pattern on one line, replacement pattern on
the next.
I will give only the literal regex text on one line followed
by the replacement on the next.
No commentary, no numbering, no separators.
You can paste directly into your regex-recipe.sh list.

expects.
If you want, I can produce a single concatenated block with no blank
lines at all, or adjust the quoting (e.g., escape slashes for sed).
M: no, i mean like this (the version i used to get the pandoc output to where it is.
G: Perfect — now that I’ve seen
your actual format (your convo-replace.txt
upload) I understand exactly what you mean.
You want literal two-line pairs, using your exact

No commentary. No blank lines inside pairs.
Each pair = two lines: FIRST: (…) and THEN: (…).

THEN:\1\2Same FIRST:/THEN: structure, no commentary inside the pairs, ready to drop directly into your sequential regex pipeline.
If you want, I can also create a version sorted by dependency or with all escaping adjusted specifically for your sed/grep engine.
M: you've made a misapprehension and a massive assumption about the 'FIRST:' label; here's the script that runs this and the directory-searching script that implements the first script sitewide.
G: [Non-text content: thoughts; content_type=thoughts]
G: [Non-text content: reasoning_recap; content_type=reasoning_recap]
G: [Non-text content: thoughts; content_type=thoughts]
G: [Non-text content: thoughts; content_type=thoughts]
G: [Non-text content: reasoning_recap; content_type=reasoning_recap]
G: You’re right, I misunderstood
how you’re using FIRST: — your script uses it only as a
“no /g” flag, not as a structural label. Thanks for
dropping the scripts; that clarified it.
So here’s what you asked for:
regex-recipe.sh expects:
FIRST: only where we want single
replacement (no g).-z -E (no (?s), no lazy
.*?).This pipeline assumes you’ve already prepended the
__BASEID__… line from the filename.
^__BASEID__([0-9]{12})__BASEID__
__BASESTAMP__\1

__LINE__g [\1]
<span class="user">M:</span>[[:space:]]*
<span class="user">G:</span>[[:space:]]*
<p>[[:space:]]*</p>
</div>
A few notes (no need to put these in the rules file):
That header rule is FIRST: so it only fires once per
file.
I’ve used literal tabs between
__LINE__m, [TS], and the HTML slot in the
replacements above. If your editor mangles them, you can:
\t,
orAfter these rules run, you’ll have:
__BASESTAMP__202506160844
<!--

__LINE__m [2025-06-16 08:44:55 EDT ] <p>user html…</p>...
__LINE__g [2025-06-16 08:44:55 EDT ] <p>assistant html…</p>...
...Your separate numbering script can then:
__BASESTAMP__YYYYMMDDHHMM once,__LINE__r\t[TS]\t with
YYYYMMDDHHMMrNNN\t[TS]\t.If you want, I can next write the tiny Perl/awk counter pass to slot
in YYYYMMDDHHMMrNNN against this exact
__LINE__ format.
