Summary of changes

Objectives from linked issues for validation

66: suda cannot handle files that include '#' in the name

Title

suda cannot handle files that include '#' in the name

Description

suda seems to be unable to handle files with '#' in the name.

I am able to reproduce this with a very minimal config, e.g.

call plug#begin('~/.local/share/nvim/plugged') Plug 'lambdalisue/suda.vim' call plug#end()

$ touch '#test'

chown root:root '#test'

$ nvim '#test'

When I open the file:

Error detected while processing BufEnter Autocommands for "*"..function suda#BufEnter: line 29: E194: No alternate file name to substitute for '#': keepalt keepjumps edit suda:///home/user/#test

on :SudaWrite:

Error detected while processing function 8_write: line 2: E194: No alternate file name to substitute for '#': write suda:///home/user/#test

Interestingly, if I call the file '##test', the write succeeds, but a file named '##testtest' is written.

Using nvim v0.9.4. Please let me know if I can provide any more information.

Walkthrough

The updates to suda.vim enhance the plugin's capability to handle file names with special characters like #. By employing fnameescape() in the relevant functions, the plugin now ensures that file paths are correctly processed, thus mitigating errors related to file name interpretation in Vim.

Poem

A hop, a skip, in the code we dive, 🐰
Fixing bugs, making plugins thrive.
Special chars in names, no more a strife,
suda.vim now handles them, oh what a life!
Cheers to paths, now tamed and neat,
With fnameescape, no defeat! 🌟

Tips

### Chat There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai): - Review comments: Directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit .` - `Generate unit testing code for this file.` - `Open a follow-up GitHub issue for this discussion.` - Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples: - `@coderabbitai generate unit testing code for this file.` - `@coderabbitai modularize this function.` - PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples: - `@coderabbitai generate interesting stats about this repository and render them as a table.` - `@coderabbitai show all the console.log statements in this repository.` - `@coderabbitai read src/utils.ts and generate unit testing code.` - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.` Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments. ### CodeRabbit Commands (invoked as PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger a review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai help` to get help. Additionally, you can add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. ### CodeRabbit Configration File (`.coderabbit.yaml`) - You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository. - Please see the [configuration documentation](https://docs.coderabbit.ai/guides/configure-coderabbit) for more information. - If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json` ### Documentation and Community - Visit our [Documentation](https://coderabbit.ai/docs) for detailed information on how to use CodeRabbit. - Join our [Discord Community](https://discord.com/invite/GsXnASn26c) to get help, request features, and share feedback. - Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.

@sserenade can you test this to ensure it works for your usecase(s)?

[sserenade]

Testing this by loading the branch in the config, with a similar test as before:

Plug 'aarondill/suda.vim',{'branch':'fix-other-file'}

$ echo 'foo' > '#test'
$ cat '#test'
foo
# chown root:root '#test'
$ nvim '#test'

On open, I get the below error and the file contents aren't loaded, though vim still thinks I'm editing a file called '#test':

[suda] Vim(read):E194: No alternate file name to substitute for '#'

I'm able to write to the file and save it, with the correct name, with no errors:

bar
:wq

$ cat '#test'
bar

However, opening the file with vim after saving it makes the above error appear again, and the file is not loaded.

[aarondill]

I think I know where this issue is. i'll work on fixing it soon

[aarondill]

@sserenade can you try with the latest commit?

[sserenade]

With the latest commit, suda now behaves as expected and appears to be able to handle the file. I get no errors upon reading or writing, the file contents are what I expect, and the filename appears correct after writing.

Thank you for your work on this!

@lambdalisue any thoughts on this before merging it?
