Steps to reproduce

project organization:

<project_root>
    .git
    src
        a.py
        b.py
    ...

Run vim a.py in src, then run LeaderfFile, try to find b.py

Actual behaviour

leaderf try to open src/b.py instead of b.py, which is invalid.

Expected behaviour

open b.py

[Yggdroot]

Sorry, I can not quite understand your issue, could you describe in more detail?

[meijieru]

@Yggdroot updated

[Yggdroot]

This works as designed, because you have set let g:Lf_WorkingDirectoryMode = 'Ac'.

LeaderF/doc/leaderf.txt

Lines 457 to 474 in 559b80a

	g:Lf_WorkingDirectoryMode *g:Lf_WorkingDirectoryMode*
	This option customizes LeaderF's working directory.
	e.g., >
	let g:Lf_WorkingDirectoryMode = 'Ac'
	<
	c - the directory of the current working directory.(default)
	a - the nearest ancestor of current working directory that contains one of
	directories or files defined in |g:Lf_RootMarkers|. Fall back to 'c' if
	no such ancestor directory found.
	A - the nearest ancestor of current file that contains one of directories
	or files defined in |g:Lf_RootMarkers|. Fall back to 'c' if no such
	ancestor directory found.
	f - the directory of the current file.
	F - if the current working directory is not the direct ancestor of current
	file, use the directory of the current file as LeaderF's working
	directory, otherwise, same as 'c'.
	Note: if "f", "F" is included with "a" or "A", use the behavior of "f" or
	"F"(as a fallback) when a root can't be found.

[meijieru]

So what does A mode design for?
It seems to be meaningful only when vim work in top of the project.

[meijieru]

The desired workflow for me is below:

1. May work in sub-dir of the project
2. Switch between the files, which may be not a sub-dir of cur-dir

Anyway to implement it?

[Yggdroot]

let g:Lf_WorkingDirectoryMode = 'Ac' meets your request.

[meijieru]

It does not.

project organize as follow

.
├── .git
└── src
    ├── a.py
    └── b.py

start from the root of the project

1. cd src
2. vim a.py
3. LeaderfFile, enter b.py<cr>
4. it will open src/src/b.py instead of src/b.py

[Yggdroot]

I think this is the bug of neovim(neovim/neovim#3636), does vim has the same behavior?

[meijieru]

Tested on vim, it works well.

[Yggdroot]

The patch for neovim/neovim#3636 has been merged, you can update neovim and have a try.

[meijieru]

I remove the neovim from pip and clone and install it by pip install ., still broken.

[Yggdroot]

I think the neovim you installed this way does not have the patch, you can install through compiling the source code.

[meijieru]

python-neovim 0.2.5 is used, where the patch has been applied.
The issue still occurs.

[Yggdroot]

Perhaps this is a new bug of neovim, I'll try to find out what it is exactly and open an issue for neovim.

[Yggdroot]

I have opened an issue for neovim: neovim/neovim#8336.

[meijieru]

I see from the doc vim.chdir may work. But it seems not recommended.

[Yggdroot]

Fixed, please have a check.

[meijieru]

It is already fixed, thanks.
