Note: 179

We noticed a bug with nbdev where nbdev export is too eager to replace "name" attributes in the pyproject.toml. So the example we had was that

[[tool.uv.index]] name = "pytorch-cpu" url = "https://download.pytorch.org/whl/cpu" explicit = true

was changed to:

[[tool.uv.index]] name = "project_name" url = "https://download.pytorch.org/whl/cpu" explicit = true

Prompt: 92

I prepared a pyproject.toml and a nbdev project in the folder "nbdev_demo". Can you print out the content of the toml file before and after nbdev-export?

Let me check the folder and show the toml file contents first.

Found it! The culprit is in config.py. Here are the key lines:

Copied!

_re_proj = re.compile(r'^name\s*=\s*".*$', re.MULTILINE)

and:

Copied!

def update_proj(path):
    "Create or update `pyproject.toml` in the project root."
    fname = path/_pyproj
    if not fname.exists(): fname.write_text(pyproj_tmpl)
    txt = fname.read_text()
    txt = _re_proj.sub(f'name = "{get_config().lib_name}"', txt)
    txt = _re_reqpy.sub(f'requires-python = ">={get_config().min_python}"', txt)
    fname.write_text(txt)

The regex r'^name\s*=\s*".*$' with re.MULTILINE matches any line starting with name = "..." anywhere in the file — it doesn't limit itself to the [project] section. So _re_proj.sub(...) replaces every name attribute it finds, including the one under [[tool.uv.index]].

The same issue likely applies to _re_reqpy too — if you had a requires-python in another section, it would also get clobbered.

Would you like to work on a fix? One approach would be to make the regex section-aware (e.g., only replace within the [project] section). Another would be to use a proper TOML library to do the update. What direction are you thinking?

Prompt: 56

ah where do you think might "requires-python" also occur?

Assistant: 144

Good question! In practice, requires-python is pretty specific to the [project] section — it's not a standard key anywhere else in pyproject.toml. So while the regex has the same section-unaware pattern, it's unlikely to cause real problems.

name on the other hand is extremely generic — it shows up in [[tool.uv.index]], inside authors lists, potentially in [tool.poetry.source], etc. That's what makes it the real problem here.

Prompt: 75

ok, then let's fix the name regex. how to only look in the project section? make a few suggestions how to tackle this?

Assistant: 303

Here are three approaches, from simplest to most robust:

Section-bounded regex — Use a regex that matches name = "..." only between [project] and the next [... header. Something like matching the whole [project] section and doing the substitution only within that matched group.
Find section boundaries, then replace within range — Parse the file to find the line range of the [project] section (from [project] to the next [ header), then apply the existing _re_proj.sub() only on that slice of text, and stitch the file back together.
Use tomlkit — A TOML library that preserves formatting, comments, and ordering. Parse → modify → write back. Most robust, but adds a dependency.

Given that nbdev already does simple regex-based text manipulation and the fix is small, I'd lean towards option 2 as the sweet spot — minimal change, no new dependency, and it properly scopes the replacement. What do you think?

Prompt: 57

let's only touch _re_proj. which regex do you suggest?

Assistant: 229

The idea is to anchor the regex to the [project] section by capturing from the [project] header up to the name line, ensuring we don't cross into another section. Something like:

Copied!

_re_proj = re.compile(r'(\[project\](?:\n(?!\[).*)*?\n)name\s*=\s*"[^"]*"')

The key piece is (?:\n(?!\[).*)*? — this matches lines between [project] and name, but refuses to cross a line starting with [ (which would be a new section header). The sub call would then use \1 to preserve the captured prefix.

Does the logic make sense? Want to try wiring it into the update_proj function?

_re_proj = re.compile(r'(\[project\](?:\n(?!\[).*)*?\n)name\s*=\s*"[^"]*"')
print(_re_proj.findall(toml))

This should show that it only captures the [project] prefix — confirming it's matching the right name line and not the one under [[tool.uv.index]].

Code: 128

import re
_re_proj = re.compile(r'(\[project\](?:\n(?!\[).*)*?\n)name\s*=\s*\"[^\"]*\"')
print(_re_proj.findall(toml))

Output:

['[project]\n']

Prompt: 49

why is only the project part shown?

Assistant: 166

Because findall returns captured groups when the pattern contains parentheses. The group (\[project\](?:\n(?!\[).*)*?\n) captures everything before the name line — and since name is the very first key after [project], the captured prefix is just [project]\n.

The important thing is: it found exactly one match, and it's the right one. Try _re_proj.search(toml).group(0) to see the full match including the name line.

_re_proj.search(toml).group(0)

    txt = _re_reqpy.sub(f'requires-python = ">={get_config().min_python}"', txt)
    fname.write_text(txt)

The only two changes are:

_re_proj uses the new section-aware pattern
The .sub() call uses rf'\1name = ...' to preserve the captured prefix (and note the r prefix so \1 isn't interpreted as an escape)

Prompt: 50

should we keep re.MULTILINE?

Assistant: 58

No — the new regex doesn't use ^ or $ anchors (it uses explicit \n for line boundaries instead), so re.MULTILINE has no effect and can be dropped.
