Instance Method Detail

def canvas_td : Array(Array(String)) #

Canvas is a variable that holds the cell of each string in grid format. In @canvas_td, each element in the array is representing a column.

Example:

@canvas_td = [["Rubys", "Crystals", "Emeralds"], ["Sappgires", "a", "b"]]

# It is Top-Down
# Rubys    Sappgires
# Crystals a        
# Emeralds b

def canvas_td=(canvas_td : Array(Array(String))) #

Canvas is a variable that holds the cell of each string in grid format. In @canvas_td, each element in the array is representing a column.

Example:

@canvas_td = [["Rubys", "Crystals", "Emeralds"], ["Sappgires", "a", "b"]]

# It is Top-Down
# Rubys    Sappgires
# Crystals a        
# Emeralds b

def col_width_td : Array(Int32) #

Holds curently max width for every column.

Example:

@canvas_td = [["Rubys", "Crystals", "Emeralds"], ["Sappgires", "a", "b"]]
@col_width_td = [8, 9]

# => 1st column width is 6 char
# => 2nd column width is 7 char
# => 3rd column width is 9 char

def col_width_td=(col_width_td : Array(Int32)) #

Holds curently max width for every column.

Example:

@canvas_td = [["Rubys", "Crystals", "Emeralds"], ["Sappgires", "a", "b"]]
@col_width_td = [8, 9]

# => 1st column width is 6 char
# => 2nd column width is 7 char
# => 3rd column width is 9 char

def one_column_td : Array(Array(String)) #

Return canvas with the size of one column. Its set @canvas_td and calculate the @col_width_td

Example:

@list = [
  "str_1",
  "str_30",
  "str_200",
  "str_4000",
  "str_50000",
]
one_column_td # => [["str_1", "str_30", "str_200", "str_4000", "str_50000"]]

def virtual_column_width_td(col_size : Int32) : Array(Int32) #

Calculate each column width for canvas with virtually col item of col_size.

Returning the width of every column in type Array(Int32)

Example:

@list = [
  "str_1",
  "str_30",
  "str_200",
  "str_4000",
  "str_50000",
]
virtual_column_width_td(3) # => [7, 9]

# Virtual column would be like
# str_1   str_4000
# str_30  str_50000
# str_200

virtual_column_width_td(2) # => [6, 8, 9]

# Virtual column would be like
# str_1  str_200  str_50000
# str_30 str_4000
