chbuf provides several functionalities:
- Jumping to loaded buffers (like
:buffercommand, but neater) — see
- Jumping to recently edited files —
- Jumping to files in current directory subtree —
- Quickly and interactively changing current working directory —
- And on Mac OS X, jumping to a file that comes from a result of Spotlight search —
All of the above share a common user interface which is that of
:help getline.txt). The philosophy is that user should be
presented with minimum information required. Prior to calling
choices are filtered (each of mentioned commands takes a regex argument) and
segment-wise shortest unique suffix is computed. In case of file system
paths, it means file base name (the last segment of a path) if it’s unique or
last two path segments if that’s unique, or last three if that’s unique and so
on until all of the path segments are taken into account, which is guaranteed
to be unique by the file system. Illustrating this on an example, the
shortest unique suffixes of:
/home/adaszko/foo /home/adaszko/bar /home/adaszko/baz/quux /home/adaszko/quux/quux
foo bar baz/quux quux/quux
and this what the user is asked to choose from.
User input is interpreted as a series of simple substrings (not a pattern of
any kind) separated by whitespace characters. Only choices containing all of
the input substrings simultaneously are shown. At any time, user may select
the first displayed choice by hitting
<CR> or abort by hitting
available keys are listed at
chbuf does not introduce any mappings by default (again, a design
philosophy). Scroll to the Setup section for this.
- Pure VimScript, no external interpreters required
- Cross-platform: Linux, Mac OS X, Windows
- Comes with library designed specifically for reuse —
getline(think readline for Vim)
Assuming you have Pathogen up and running:
$ cd ~/.vim/bundle $ git clone git://github.com/adaszko/chbuf.vim $ vim -c :Helptags -c :q
Simply add a mapping of your choice to your
noremap <silent> <Leader>b :ChangeBuffer<CR> noremap <silent> <Leader>B :ChangeMixed<CR> noremap <silent> <Leader>f :ChangeFile<CR> noremap <silent> <Leader>c :ChangeDirectory<CR>
Note that functions above respect
@tpope for his excellent taste for Vim plugin design and much code to learn from.
chbuf came into existence as a simple demo of
getline, which in turn has
been created for the needs of
orgdt. I realised at some point that no other
plug-in of this kind is compatible with my work flow and design requirements.
Also, I get the impression that Spotlight (and its
mdfind command line
counterpart) is under-utilised for such a fast and powerful tool.
It's generally slower and “flickers” on Windows.
