From ac9060ab3a5af6c1062a399f0655b0747d3d5704 Mon Sep 17 00:00:00 2001 From: catlog22 Date: Sun, 14 Dec 2025 16:10:59 +0800 Subject: [PATCH] fix(codex-lens): refine CLI exception handling with specific error types MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace overly broad `except Exception` blocks with specific exception handlers (StorageError, ConfigError, ParseError, SearchError, PermissionError) across all CLI commands. This provides more precise error messages and improves debugging experience for end users. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- codex-lens/src/codexlens/cli/commands.py | 351 ++++++++++++++++++++++- 1 file changed, 342 insertions(+), 9 deletions(-) diff --git a/codex-lens/src/codexlens/cli/commands.py b/codex-lens/src/codexlens/cli/commands.py index 1e2ad9b0..66240246 100644 --- a/codex-lens/src/codexlens/cli/commands.py +++ b/codex-lens/src/codexlens/cli/commands.py @@ -15,7 +15,7 @@ from rich.table import Table from codexlens.config import Config from codexlens.entities import IndexedFile, SearchResult, Symbol -from codexlens.errors import CodexLensError +from codexlens.errors import CodexLensError, ConfigError, ParseError, StorageError, SearchError from codexlens.parsers.factory import ParserFactory from codexlens.storage.path_mapper import PathMapper from codexlens.storage.registry import RegistryStore, ProjectInfo @@ -124,12 +124,42 @@ def init( if build_result.errors: console.print(f" [yellow]Warnings:[/yellow] {len(build_result.errors)} errors") -
