How to keep every row the same width

[walkinrain2008]

from rich.console import Console

mycon = Console(record = True)

mycon.width=20
# mycon.soft_wrap = True
s ="a"*25
mycon.print(s)

for i in range(10):
    s="b"*5
    mycon.print(s,end=",")

result is

aaaaaaaaaaaaaaaaaaaa
aaaaa
bbbbb,bbbbb,bbbbb,bbbbb,bbbbb,bbbbb,bbbbb,bbbbb,bbbbb,bbbbb,

i wish like :

aaaaaaaaaaaaaaaaaaaa
aaaaa
bbbbb,bbbbb,bbbbb,bb
bbb,bbbbb,bbbbb,bbbb
b,bbbbb,bbbbb,bbbbb,

The issue is that end="," prevents Rich from inserting line breaks — it joins all the print outputs on a single line, which then wraps based on the terminal/console width.

To get consistent-width output that wraps at exactly console.width, you have a few options:

Option 1: Build the string yourself and let Rich wrap it

from rich.console import Console
from rich.text import Text

con = Console(width=20, record=True)

s = "a" * 25
con.print(s)

# Build the full string, then print it as a single unit
parts = ",".join(["b" * 5 for _ in range(10)]) + ","
con.print(Text(parts, overflow="fold"))

The overflow="fold" setting ensures the text is hard-wrapped at exactly console.width characters (no word-break logic).

Option 2: Use Text with no_wrap=False (default)

from rich.console import Console
from rich.text import Text

con = Console(width=20, record=True)

long_text = Text("a" * 25, overflow="fold")
con.print(long_text)

repeated = Text(",".join(["b" * 5] * 10) + ",", overflow="fold")
con.print(repeated)

Output:

aaaaaaaaaaaaaaaaaaaa
aaaaa
bbbbb,bbbbb,bbbbb,bb
bbb,bbbbb,bbbbb,bbbb
b,bbbbb,bbbbb,bbbbb,

The key is overflow="fold" on the Text object — this tells Rich to break at exactly the console width rather than trying to break at word boundaries.

Is there any other way？
In my usage, I set the Console in a separate py file. When another program references and runs a standalone py file, use record to output the contents and export them for page display.
So the change you proposed to print content is not suitable for my program. (Independent procedure changes required)
Then in the console, end=","Normal folding.
I understand that Console should be a replacement for the console, and Console(width=??) should ensure normal folding. Can you create a visual warp by modifying some of the CSS styles of the export_html?

ah i see, so u cant change the print calls bc they come from other scripts — makes sense. two options that work without touching the print code:

option 1: CSS via code_format — let the browser handle wrapping:

html = con.export_html(
    code_format=(
        '<pre style="font-family:monospace; white-space:pre-wrap; '
        'word-break:break-all; max-width:20ch;">'
        '<code style="font-family:inherit">{code}</code></pre>'
    )
)

option 2: re-record with fold — post-process the recorded text before exporting:

from rich.text import Text

# after recording is done, re-record with fold wrapping
raw_text = con.export_text()
con2 = Console(record=True, width=20)
for line in raw_text.strip().splitlines():
    con2.print(Text(line, overflow="fold"))
html = con2.export_html()

i think both should work, just pick whichever fits ur setup better and go from there :) good luck!

option1 is very convenient, I directly associate the max-width value with console.width to fully achieve the goal.
Thank you for your help

How to keep the {code} section's automatic colors (for example: numbers in green)

[murriiii]

just add inline_styles=True — that puts the colors directly in the <span> tags instead of using CSS classes (which get lost when u use a custom code_format):

html = con.export_html(
    inline_styles=True,
    code_format=(
        '<pre style="font-family:Menlo,monospace; white-space:pre-wrap; '
        'word-break:break-all; max-width:20ch;">'
        '<code style="font-family:inherit">{code}</code></pre>'
    )
)

this way the {code} contains stuff like <span style="color: #008000; font-weight: bold">42</span> instead of <span class="r2">42</span>, so the colors work without needing a separate <style> block
