From dfd936f126e950ee8687cc3b30d90414a963c849 Mon Sep 17 00:00:00 2001 From: alihassanoo <57753201+alihassanoo@users.noreply.github.com> Date: Fri, 3 May 2024 14:17:30 +0500 Subject: [PATCH 1/2] Refactor parse_script function for readability and maintainability This commit refactors the parse_script function to enhance readability and maintainability. Changes include: - Improved documentation with detailed explanations of the function's behavior, input, and output. - Renamed variable 'n_delimiters' to 'delimiter_count' for clarity. - Used specific exception handling instead of catching generic 'Exception'. - Combined two try-except blocks into one for better code organization. - Added comments to clarify complex logic and edge cases. - Enhanced function signature by specifying types of exceptions raised. These changes aim to make the codebase more understandable and easier to maintain, without altering its functionality. --- src/rawdog/parsing.py | 34 ++++++++++++++++++++++++---------- 1 file changed, 24 insertions(+), 10 deletions(-) diff --git a/src/rawdog/parsing.py b/src/rawdog/parsing.py index 0bbc00f..b9664b3 100644 --- a/src/rawdog/parsing.py +++ b/src/rawdog/parsing.py @@ -5,25 +5,39 @@ def parse_script(response: str) -> tuple[str, str]: """Split the response into a message and a script. - Expected use is: run the script if there is one, otherwise print the message. + The function splits the response by '```' delimiters, extracting the message and script parts. + It checks for common mistakes, such as 'python' prefix and attempts to parse the script as JSON. + Finally, it validates the script as valid Python code using ast module. + + Args: + response (str): The input response containing a message and optionally a script. + + Returns: + tuple[str, str]: A tuple containing the message (or error message) and the script.

Changes include: 1. Consolidated error handling in a single try-except block to improve error management. 2. Enhanced prefix removal using regex for better handling of variations and whitespace. 3. Optimized script handling by decoding and re-encoding JSON, ensuring input to syntax validation is consistently a string. 4. Simplified message and script extraction by improving segment splitting and concatenation. These updates improve the function's adaptability and reliability across different input formats. --- src/rawdog/parsing.py | 56 +++++++++++++++++++++---------------------- 1 file changed, 27 insertions(+), 29 deletions(-) diff --git a/src/rawdog/parsing.py b/src/rawdog/parsing.py index b9664b3..860a3db 100644 --- a/src/rawdog/parsing.py +++ b/src/rawdog/parsing.py @@ -1,43 +1,41 @@ import ast import json +import re def parse_script(response: str) -> tuple[str, str]: - """Split the response into a message and a script. - - The function splits the response by '```' delimiters, extracting the message and script parts. - It checks for common mistakes, such as 'python' prefix and attempts to parse the script as JSON. - Finally, it validates the script as valid Python code using ast module. + """Split the response into a message and a script, handling variations of 'python' prefix and JSON content.
