One does not need to constrain the questions users ask or the responses of the AI to single sentences or even single lines or paragraphs in the fine-tune examples. Complete verbose replies can be written out.
Use the \n character for line breaks and use other escaping of special characters within the strings.
Here is a long question a user might input:
User prompt, asking for coding
Code Snippet with two functions:
def updateLabelText(self):
font = self.label.font()
available_width = self.width() - self.label.contentsMargins().left() - self.label.contentsMargins().right()
self.short_message = (self.original_text[0:124].replace("\n", "¶")[:121].rstrip() + "...") \
if len(self.original_text) > 125 else self.original_text.replace("\n", "¶") # shorten
if not self.parent() or self.size() == QSize(0, 0) or not self.isVisible() or not self.layout():
return "" # Not ready, return default
truncated_text = self.short_message[:self.calculateTruncationPoint(font, available_width)]
if not self.short_message == truncated_text:
truncated_text += ".."
self.label.setText(truncated_text)
def calculateTruncationPoint(self, font, available_width):
elide_marker = ".."
font_metrics = QFontMetrics(font)
if len(self.short_message) < 20:
return len(self.short_message)
text_width = font_metrics.horizontalAdvance(self.short_message)
marker_width = font_metrics.horizontalAdvance(elide_marker)
for i in range(18, 120, 2):
truncated_text = self.short_message[:i] + elide_marker
truncated_width = font_metrics.horizontalAdvance(truncated_text)
if truncated_width + marker_width >= available_width or i > 110:
return i - 2
return 0
The above is methods of Python 3.8 and PyQt5 subclassed QWidget code to determine the amount of text that will fit within a widget’s QLabel horizontally. However it is quite slow at processing. You will implement a binary search algorithm for the truncation point search, and will also uses a self.last_length int variable to store in the subclass object to enhance the speed of later label text updates after resize events.
And if the AI couldn’t perform the task before, or if you want it to do it without the extensive instructions it required before, you train it how to answer with the assistant response it should give:

Sure, I can help you implement the binary search algorithm for the truncation point search and incorporate the self.last_length variable. Here’s the updated version of your code with these modifications:
class YourSubclass(QWidget):
def __init__(self, parent=None):
super().__init__(parent)
self.label = QLabel(self)
self.short_message = ""
self.original_text = ""
self.last_length = 0
def updateLabelText(self):
font = self.label.font()
available_width = self.width() - self.label.contentsMargins().left() - self.label.contentsMargins().right()
self.short_message = (self.original_text[0:124].replace("\n", "¶")[:121].rstrip() + "...") \
if len(self.original_text) > 125 else self.original_text.replace("\n", "¶") # shorten
if not self.parent() or self.size() == QSize(0, 0) or not self.isVisible() or not self.layout():
return "" # Not ready, return default
if self.width() != self.last_length:
self.calculateTruncationPoint(font, available_width)
self.last_length = self.width()
truncated_text = self.short_message[:self.last_truncation_point]
if not self.short_message == truncated_text:
truncated_text += ".."
self.label.setText(truncated_text)
def calculateTruncationPoint(self, font, available_width):
elide_marker = ".."
font_metrics = QFontMetrics(font)
if len(self.short_message) < 20:
self.last_truncation_point = len(self.short_message)
return
text_width = font_metrics.horizontalAdvance(self.short_message)
marker_width = font_metrics.horizontalAdvance(elide_marker)
left = 18
right = min(120, len(self.short_message))
last_fit = -1
while left <= right:
mid = (left + right) // 2
truncated_text = self.short_message[:mid] + elide_marker
truncated_width = font_metrics.horizontalAdvance(truncated_text)
if truncated_width + marker_width <= available_width:
last_fit = mid
left = mid + 1
else:
right = mid - 1
if last_fit == -1:
self.last_truncation_point = 0
else:
self.last_truncation_point = last_fit - 2
In this implementation, the calculateTruncationPoint method uses binary search to find the optimal truncation point that fits within the available width. The self.last_length variable is used to keep track of the widget’s width and determine if a recalculation of the truncation point is necessary after resize events. The self.last_truncation_point stores the last calculated truncation point, enhancing the speed of later label text updates.
Please integrate this code into your project, and ensure that you have PyQt5 properly set up in your environment.
And here is the single line of training example with system, user, assistant roles. (long enough to probably blow up the forum)
