Background Information

The /diff command is a powerful tool in Codex, allowing users to compare the differences between two commits or branches. However, when dealing with filenames that contain special characters, this command may error out, preventing users from accessing the desired information.

System Specifications

To better understand the issue, it's essential to provide some system specifications:

Codex Version: 0.1.2504301751
Model: o4-mini
Platform: Linux (x64) with WSL2 (5.15.153.1-microsoft-standard-WSL2)

Reproducing the Bug

To reproduce the bug, follow these steps:

Create a Temporary Git Repository: Create a new temporary Git repository using the command git add . && git commit -m "Initial commit".
Create a File with Special Characters: Create a new file with a name containing special characters, such as a$b.txt.
Run /diff: Run the /diff command to compare the differences between the current commit and the previous commit.

Expected Behavior

When running the /diff command, the expected behavior is to display the differences between the two commits. However, when dealing with filenames containing special characters, the command may error out, displaying an error message.

Resolving the Issue

To resolve the issue, follow these steps:

Update Codex: Ensure that the Codex platform is up-to-date by running the command codex update.
Use the --ignore-case Option: When running the /diff command, use the --ignore-case option to ignore case sensitivity when comparing filenames. This can be done by running the command codex diff --ignore-case.
Use the --ignore-space-at-eol Option: Additionally, use the --ignore-space-at-eol option to ignore space characters at the end of lines when comparing files. This can be done by running the command codex diff --ignore-case --ignore-space-at-eol.

Example Use Cases

Here are some example use cases that demonstrate the resolution of the issue:

Comparing Commits: Run the command codex diff --ignore-case --ignore-space-at-eol to compare the differences between two commits.
Comparing Branches: Run the command codex diff --ignore-case --ignore-space-at-eol to compare the differences between two branches.
