maintenance: raw-string the LaTeX-carrying docstrings - #47
Merged
Conversation
Non-raw docstrings containing LaTeX are corrupted by Python's escape handling.
Two distinct failure classes, and only the first is visible:
warned `\s`, `\l`, `\[` ... escapes Python does NOT recognise. It leaves
them literal but emits SyntaxWarning on every compile/import, and
they are slated to become a SyntaxError.
silent `\t` in `\theta`, `\f` in `\frac`, `\r` in `\rm`, `\b` in `\beta`.
Escapes Python DOES recognise: the value is corrupted with NO
diagnostic at all. `\theta_E` was literally TAB + "heta_E".
13 literals across 4 files get the `r` prefix. Both sweeps now return zero.
Verified, not assumed:
- Runtime values: 7 corruptions repaired, 0 other changes. Each changed
literal's value was compared HEAD vs worktree; the prefix may only ever
REMOVE corruption, never alter a string otherwise.
- Regenerated with autohands: markdown/, llms-full.txt and workspace_index.json
are byte-identical. The only notebook delta is the four `plt.ylabel` labels,
which are runtime strings in CODE cells, so the source change is meant to
show there. Prose cells are unchanged.
Deliberate escapes were left alone: `print("\nInfo:")` and friends keep their
real newlines, and `" \\[-2pt]"` keeps its already-escaped LaTeX line break.
The prefix was only applied where every backslash sits in a LaTeX context
($...$, \(...\), \[...\], \begin{}...\end{}, or a markdown code span).

Part of PyAutoLabs/autolens_workspace#491 — one of six independent, prose-only PRs (one per workspace repo). No API surface, so no cross-repo merge ordering.

Two notebooks change, and both are expected. The four
plt.ylabel("Normalized Residuals ($\sigma$)")labels are runtime strings in code cells, not docstrings — code cells copy source verbatim, so theris meant to show there. Every prose cell is unchanged. This is the only repo of the six with such a delta.Left alone deliberately

The prefix was applied only where every backslash in the literal sits in a LaTeX context ($…$,\(…\),\[…\],\begin{}…\end{}, or a markdown code span), with an absolute veto on\\, escaped quotes and numeric escapes regardless of context.Unblocked by PyAutoHands#251, which taught the notebook and env parsers to accept an
