From 4a76132cbe9b2605e198a2f07b1fb329d9a8ce81 Mon Sep 17 00:00:00 2001 From: Sergey Alexandrov Date: Mon, 10 Mar 2014 12:13:18 +0100 Subject: [PATCH] Fix "Cannot use empty key for Dictionary" error This commit resolves compatibility issue with fugitive plugin. When using "Gdiff" command on some file, fugitive attempts to open the current and the index version of the file. For example, if the file is /home/taketwo/path/to/the/project/README.md then fugitive will use the following path to open the index version: fugitive:///home/taketwo/path/to/the/project/.git//0/README.md Opening this file leads to a cascade of errors like this: Error detected while processing function airline#extensions#tabline#get..162_get_buffers..162_get_visible_buffers..airline#extensions#tabline#get_buffer_name..airline#extensions#tabline#unique_tail_improved#format: line 20: E713: Cannot use empty key for Dictionary The problem is that when a filename like this is being tokenized, there appear empty "" tokens, and an error occurs when using them as keys in `path_tokens[token_index]` dictionary. This fix simply skips empty tokens. --- autoload/airline/extensions/tabline/unique_tail_improved.vim | 1 + 1 file changed, 1 insertion(+) diff --git a/autoload/airline/extensions/tabline/unique_tail_improved.vim b/autoload/airline/extensions/tabline/unique_tail_improved.vim index 1b4dfa3f..6b13dcf0 100644 --- a/autoload/airline/extensions/tabline/unique_tail_improved.vim +++ b/autoload/airline/extensions/tabline/unique_tail_improved.vim @@ -19,6 +19,7 @@ function! airline#extensions#tabline#unique_tail_improved#format(bufnr, buffers) let tokens = reverse(split(substitute(fnamemodify(name, ':p:.:h'), '\\', '/', 'g'), '/')) let token_index = 0 for token in tokens + if token == '' | continue | endif if token == '.' | break | endif if !has_key(path_tokens, token_index) let path_tokens[token_index] = {}
