line-repeater 1.1.1

A simple CLI tool that repeats lines of text.

prayer-pause

A utility for repeating lines, or blocks of lines. Available as a CLI tool, a desktop GUI, and a Python package.

Features

• Repeat each line (or a block of N lines) a configurable number of times
• Insert a custom separator between each repetition of a line (--line-sep)
• Insert a custom separator between each repeated block (--block-sep)
• Three interfaces: CLI, GUI, and importable Python package
• Handles edge cases: skips blank lines, strips trailing whitespace inconsistencies, validates input bounds

Installation

You can either get the pip package for CLI use. Or download the GUI app.

Standalone Executable

Download the latest .exe from the Releases page. No Python installation required.

Using pip

pip install line-repeater

2. Paste (or type) your text into the text box, fill in the parameters, and click Run. The result replaces the content in the text box in place.

Parameters:

Field	Description	Default

Repeat blocks of 2 lines, 4 times each, with a === block separator:

API

The repeater function can be imported and used directly in your code.

from line_repeater import repeater

with open("file.txt", "r+") as f:
    repeater(
        file=f,                 # File-like object opened in read+write mode
        repeat_n_times=3,       # int - how many times to repeat each line/block
        till_line=1,            # int - block size (number of lines per block)
        block_line_sep="\n",    # str - separator between blocks
        line_sep="---",         # str | None - separator between repetitions
    )

Note: repeater() modifies the file in-place. Make sure to open it in r+ mode.

Exceptions:

Exception	Condition
ValueError	File/buffer is empty
ValueError	till_line exceeds the number of lines in the file
