In your new loop that finds children, you have: if (pe32.th32ProcessID == pid) {
// ...
if (pe32.th32ParentProcessID == targetpid) {
// add to lists
}
}The problem: you're only processing when the current process ID equals your target pid, but then you're also checking if that same process is a child of the target. That's contradictory - a process can't be both "the target" and "a child of the target" at the same time. What you actually want: Just loop through all processes and check if their parent is the target pid. No need for that outer if (pe32.th32ParentProcessID == targetpid) {
// This process is a child of our target!
exeName = WideToString(pe32.szExeFile);
exeNames.emplace(exeNames.begin(), exeName);
pidNames.emplace(pidNames.begin(), pe32.th32ProcessID);
}This way you'll catch ALL children of the target process, not just... well, nothing with the current logic 😅 Also yeah, your TODO about the emplace inefficiency is spot-on - you could collect children in a separate list and append them, or just iterate the snapshot once total. But get the logic working first, optimize later! Keep at it, you're on the right track! 🚀 🧠 Learnings used |

Those errors are totally normal when you're in the thick of it:
But hey, you made solid progress! Getting the logic structure in place is the hard part - syntax is just polish. The compiler's just being picky 😅 Enjoy your weekend, and you'll knock those out in no time on Saturday! 🎉 🧠 Learnings used |

The approach is spot-on now - you nailed the logic I mentioned earlier! Checking Big props for:
One sneaky bug though that'll bite you harder than the syntax stuff: if (pe32.th32ParentProcessID == targetpid) {
// ... add to lists
}
found = true;
break; // ← THIS IS THE PROBLEM!That Also heads up - your color output logic at line 322 starts an if block but never actually prints anything inside it. Looks like you were mid-thought there 😄 But seriously, you got the hard part down! The logic is solid now. Once you squash those syntax errors Saturday, you'll be golden ✨ 🧠 Learnings used |

Makes perfect sense why that At least you got the core logic change in (removing that weird outer if check), so the hard thinking is done! Saturday you'll just be cleaning up the messy edges. Should be a quick fix - just yank that You got this! 💪 🧠 Learnings used |

Look at lines 316-319 in your diff: for (size_t j = 0; j < i; j++) {
if (i > pidNames.size() - children) {
std::cout << " "; // this adds indentation
}
}That looks fine, BUT then immediately after on line 320, you have: if (i > 0) {This What you probably meant: The indentation logic should be inside the for (size_t j = 0; j < i; j++) {
if (i > pidNames.size() - children) {
std::cout << " ";
}
}
// Now we're outside the indentation loop, print the branch character
if (i > 0) {
if (IsVirtualTerminalModeEnabled()) {
std::cout << "\033[35m└─\033[0m ";
} else {
std::cout << "└─ ";
}
}
// Then print the process name/PID...Right now your braces are all over the place (classic "bell's about to ring" coding 😂), causing the display code to loop weirdly and print everything multiple times. TL;DR: Your child collection logic is fine! Just gotta fix those braces in the display section so each process prints exactly once. Saturday mission: brace matching! 🎯 🧠 Learnings used |

The problem: Your condition at line 317 is doing two things wrong:
What's happening:
But all children should have the same depth! They're all siblings. The fix for the indentation loop (lines 316-320): // Figure out the depth first
size_t depth;
if (i >= pidNames.size() - children) {
// This is a child process - all children have same depth
depth = pidNames.size() - children;
} else {
// This is an ancestor or the target - depth = index
depth = i;
}
// Now print the indentation
for (size_t j = 0; j < depth; j++) {
std::cout << " ";

Look at your display loop (lines 316-319): for (size_t j = 0; j < i; j++) {
if (i > pidNames.size() - children) {
std::cout << " "; // this adds indentation
}
}The problem: For each child, this inner loop runs
All the children should be siblings at the same indentation level, but your code treats them like a nested chain! The fix: Children should all get exactly ONE level of indent, while ancestors get progressive indent based on their depth. Try this: // Indentation logic
if (i < children) {
// This is a child - give it ONE level of indent
std::cout << " ";
} else {
// This is an ancestor - indent based on depth
// (how far from the target)
size_t ancestorDepth = i - children;
for (size_t j = 0; j < ancestorDepth; j++) {
std::cout << " ";
}
}This way all children get the same indent, and ancestors get progressively more indent as you go up the tree 🎯 🧠 Learnings used |

win-witr v0.1.0Basically my entire if statement was wrong. I just had to flip it from a > to a < because I messed up, I wanted to make it so only the children of a process didn't get indented (since they're siblings) so I used the children variable. The other thing you said about process exited, well that was just a leftover from back when the tree was flipped. In reality that was supposed to check for the top ancestor. But now, why is it that sometimes, not even the process itself I called shows up? Like look at what happened to wininit.exe |

The issue is on line 325 - you have Look at your display loop: for (size_t i = 0; i < nameSize; i++) {
// ... indentation logic
if (i > 0) { // ← This skips everything when i == 0!
// print the └─ character
// print the process name
// print the PID
// ALL OF THIS IS SKIPPED for index 0
}
}What's happening with wininit.exe: But then:
The fix: Only the branch character for (size_t i = 0; i < nameSize; i++) {
// ... your indentation logic stays the same
// Only print the branch for non-first items
if (i > 0) {
if (IsVirtualTerminalModeEnabled()) {
std::cout << "\033[35m└─\033[0m ";
} else {
std::cout << "└─ ";
}
}
// But ALWAYS print the process name/PID (moved outside the if!)
if (IsVirtualTerminalModeEnabled()) {
if (targetpid == pidNames[i]) {
std::cout << "\033[1;32m" << exeNames[i] << " (PID " << pidNames[i] << ")\033[0m" << std::endl;
} else {
std::cout << exeNames[i] << " (PID " << pidNames[i] << ")" << std::endl;

} else {
std::cout << exeNames[i] << " (PID " << pidNames[i] << ")" << std::endl;
}
}
}This way the first process prints without a branch, and all subsequent ones get the 🧠 Learnings used |

Look at that beautiful output! Everything is displaying correctly now: ✅ wininit.exe shows up as the first process (index 0 fixed!) That 5-hour bug hunt was totally worth it! You basically had to move like 20 lines of code outside that Your process tree implementation is now solid! The indentation logic is clean, the child enumeration works perfectly, and the display is exactly what you wanted. Nice work pushing through! 💪 Time to merge this beast? 🚀 🧠 Learnings used |

In `@main.cpp`:
- Around line 311-317: The code currently computes lastParentTime (via
GetProcessCreationTime) and lastChildTime (from exeTimes) but always prints
"[Parent Process Exited]"; update the logic in the block that uses
parentPids.front(), GetProcessCreationTime, and exeTimes.front() so the message
only prints when the parent is actually gone or older than the child: e.g.,
check if lastParentTime == 0 (parent not found) or lastParentTime <
lastChildTime before calling std::cout, otherwise skip printing; keep using
parentPids, exeTimes, and GetProcessCreationTime to perform this conditional
check.
- Around line 323-327: The indentation loop incorrectly skips base indentation
for child entries because it uses the condition (i < nameSize - children); fix
by computing an explicit depth for each item (e.g., depth = i for ancestors and
depth = (nameSize - children + childIndex) or depth = parentDepth+1 for
children) and then run the j-loop from 0 to depth to print the correct number of
" " entries; update the code that prints the single " " (later at the print
site) to use this computed depth instead of assuming depth 1 so children are
indented to the true depth of the target process.
In `@tests/process/process.bat`:
- Line 4: Remove the trailing whitespace at the end of the line containing
"win-witr wininit.exe" in tests/process/process.bat; edit the line so it ends
exactly with "wininit.exe" (no extra space or tab) to prevent batch parser or
test framework misinterpretation.
🧹 Nitpick comments (3)
main.cpp (3)
286-288: Storing placeholder/incorrect data in vectors is confusing and error-prone.Line 287 stores the child's own PID in
parentPids(not its parent), and line 286 stores time data that's acknowledged as unused. While the vectors need equal lengths, this approach can cause bugs if someone later usesparentPidsexpecting actual parent PIDs.Consider either:
- Storing the correct parent PID (
targetpid) for children- Using a struct to hold process data together, avoiding parallel vectors entirely
♻️ Minimal fix for parentPids
- exeTimes.emplace(exeTimes.begin(), childTime); // we don't even use this but we need to keep all the vectors the same length - parentPids.emplace(parentPids.begin(), pe32.th32ProcessID); // just fill it up, we aren't using it + exeTimes.emplace(exeTimes.begin(), childTime); + parentPids.emplace(parentPids.begin(), targetpid); // child's actual parent is targetpid
328-358: Consider simplifying the nested conditionals for readability.The current brace placement (e.g.,
}}on line 335) and deep nesting make this block harder to follow. The logic is correct, but extracting the VT check or using early returns/continues could improve clarity.♻️ Simplified structure

361-364: Inconsistent brace indentation.The closing braces here have unusual indentation. While syntactically correct, aligning them properly would improve readability.
