#
char_at

source

fn char_at(line : Int, column : Int, replacement : String, unit? : PosUnit) -> Replacement

Creates a Replacement for a char in the text.

Parameters

line: The line number (0-based) where the replacement occurs.
column: The column number (0-based) where the replacement occurs.
replacement: The string to insert at the specified point.

#
multiline

source

fn multiline(start : (Int, Int), end : (Int, Int), replacement : String, unit? : PosUnit) -> Replacement

Creates a Replacement for a range that spans multiple lines.

Parameters

start: A tuple (line, column) representing the start of the range (0-based, in UTF-16 code units).
end: A tuple (line, column) representing the end of the range (0-based, in UTF-16 code units, inclusive).
replacement: The string to replace the specified range.

#
point

source

fn point(line : Int, column : Int, replacement : String, unit? : PosUnit) -> Replacement

Creates a Replacement for a single point in the text, referring to the left side of the character.

Parameters

line: The line number (0-based) where the replacement occurs.
column: The column number (0-based) where the replacement occurs.
replacement: The string to insert at the specified point.

#
range

source

fn range(line : Int, start_column : Int, end_column : Int, replacement : String, unit? : PosUnit) -> Replacement

Creates a Replacement for a range in a single line.

Parameters

line: The line number (0-based) where the replacement occurs.
start_column: The starting column number (0-based, in UTF-16 code units) of the range.
end_column: The ending column number (0-based, in UTF-16 code units, inclusive) of the range.
replacement: The string to replace the specified range with.

#
splice

source

fn splice(template : StringView, replacements : Array[Replacement]) -> String

Splices substrings in template at the specified ranges with the given replacements.

The replacement ranges must not overlap.

Parameters

template: The original string to perform splicing on.
replacements: An array of Replacement structs specifying the ranges and their replacements.

Returns

The modified string after applying all replacements.

Exceptions

Raises an Error if any of the specified ranges are invalid or out of bounds.

Examples

let template =
  #|fn get(🐰){
  #| ...
  #| ...
  #| h($)
  #|}
inspect(
  splice(template, [
    multiline((1, 1), (2, 3), "f(x)\n g()"),
    range(0, 7, 7, "x : Int"),
    point(0, 9, " -> Int "),
    char_at(3, 3, "1001"),
  ]),
  content=(
    #|fn get(x : Int) -> Int {
    #| f(x)
    #| g()
    #| h(1001)
    #|}
  ),
)
