intern returns a canonical version of the string, reducing memory usage

parseNumericValueFast quickly parses a string to float64 Handles commas, underscores, and returns 0 for invalid values

truncateText truncates text to maxWidth and adds ellipsis if needed

wrapText wraps text to fit within maxWidth characters Returns the wrapped text with newlines

I2B covert int to bool, if i >0:true, else false

getCol returns the ith column data as a string slice Uses pointer receiver to avoid copying mutex

newStringInterner creates a new string interner

resizeCol adjusts the number of columns (thread-safe)

sortByDate sorts column by date format with optimized date parsing

updateFooterWithStatus updates the footer with a status message

autoDetectColumnType intelligently detects if a column contains numeric, date, or string data Returns colTypeDate for dates, colTypeFloat for numbers,

buildFilterInfoStr builds the filter information string for the top strip Shows all active filters or current column filter when cursor is on a filter

check ith column should be displayed or not

draw app UI

Get candidate separators from first line

get suitable scanner(compressed or not)

getPlot generates a bar chart visualization for discrete data

isDateValue checks if a string represents a valid date with fast pre-checks

isNumericValue checks if a string represents a valid number Handles: integers, floats, scientific notation, negative numbers

Fast validation: Check if a separator is valid for all lines

loadAndDisplaySync handles the complete sync loading workflow

load file content to buffer (async version with concurrent parsing)

load console pipe content to buffer (async version for progressive rendering)

makeProgressBar creates a visual progress bar percent should be between 0 and 100 width is the number of characters for the bar

resizeColUnsafe adjusts the number of columns (must be called with lock held) Fills missing columns with "NaN"

runApp starts the UI application if not in debug mode

setupFreezeMode configures row and column freeze settings based on header mode

shouldInternColumn determines if a column should use string interning based on its cardinality (ratio of unique values to total values)
