weave

A collection of (ANSI-sequence aware) text reflow operations & algorithms. A project to learn Mojo, Go, and how to work with buffers.

I've only tested this on MacOS VSCode terminal so far, so your mileage may vary!

Wrap (Unconditional Wrapping)

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

from weave import indent
from weave import wrap
from weave import wordwrap
from weave import dedent
from weave import padding
from weave import truncate

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

Output

Hello
Sekai
!

Wordwrap

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

from weave import indent
from weave import wrap
from weave import wordwrap
from weave import dedent
from weave import padding
from weave import truncate

fn main() raises:
    print(wordwrap.apply_wordwrap("Hello Sekai!", 6))

Output

Hello
Sekai!

ANSI Example

print(wordwrap.apply_wordwrap("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
from weave import wrap
from weave import wordwrap
from weave import dedent
from weave import padding
from weave import truncate

fn main() raises:
    print(indent.apply_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 indent
from weave import wrap
from weave import wordwrap
from weave import dedent
from weave import padding
from weave import truncate

fn main() raises:
    print(dedent.apply_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 indent
from weave import wrap
from weave import wordwrap
from weave import dedent
from weave import padding
from weave import truncate

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

Output

Hello
World
This is my text!

Truncate

from weave import indent
from weave import wrap
from weave import wordwrap
from weave import dedent
from weave import padding
from weave import truncate

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

Output

abcde

Chaining outputs

from weave import wrap
from weave import padding


fn main() raises:
    print(padding.apply_padding(wrap.apply_wrap("Hello Sekai!", 5), 5))

Output

Hello
Sekai
!
