weave

A collection of (ANSI-sequence aware) text reflow operations & algorithms.

Ported from/inspired by: https://github.com/muesli/reflow/tree/master

Installation

1. First, you'll need to configure your mojoproject.toml file to include my Conda channel. Add "https://repo.prefix.dev/mojo-community" to the list of channels.
2. Next, add weave to your project's dependencies by running magic add weave.
3. Finally, run magic install to install in weave and its dependencies. You should see the .mojopkg files in $CONDA_PREFIX/lib/mojo/ (usually resolves to .magic/envs/default/lib/mojo).

Wrap (Unconditional Wrapping)

The wrap module lets you unconditionally wrap strings or entire blocks of text.

from weave import wrap

fn main():
    print(wrap("Hello Sekai!", 5))

Output

Hello
Sekai
!

Word wrap

The word_wrap package lets you word-wrap strings or entire blocks of text.

from weave import word_wrap

fn main():
    print(word_wrap("Hello Sekai!", 6))

Output

Hello
Sekai!

ANSI Example

print(word_wrap("I really \x1B[38;2;249;38;114mlove\x1B[0m Mojo!", 10))

Indent

The indent module lets you indent strings or entire blocks of text.

from weave import indent

fn main():
    print(indent("Hello\nWorld\n  TEST!", 5))

Output

     Hello
     World
       TEST!

Dedent

The dedent module lets you dedent strings or entire blocks of text. It takes the minimum indentation of all lines and removes that amount of leading whitespace from each line.

from weave import dedent

fn main():
    print(dedent("    Line 1!\n  Line 2!"))

Output

  Line 1!
Line 2!

Padding

The padding module lets you right pad strings or entire blocks of text.

from weave import padding

fn main():
    print(padding("Hello\nWorld\nThis is my text!", 15))

Output

Hello
World
This is my text!

Truncate

from weave import truncate

fn main():
    print(truncate("abcdefghikl\nasjdn", 5))

Output

abcde

Chaining outputs

from weave import wrap
from weave import padding

fn main():
    print(padding(wrap("Hello Sekai!", 5), 5))

Output

Hello
Sekai
!

TODO

• Handle different types of whitespace.
