Vim plugin to search files, tags, lines and matches
(demonstration).

Installation

It is recommended to use a plugin manager like vim-plug or others.

Plug 'damage220/vim-finder'

Synopsis

Function	Command	Description
finder#files([options])	Files [directory] [openBufferCommand]	List files. Be careful, by default, files are shown in the current buffer. See openBufferCommand below.
finder#tags([options])	Tags	List buffer tags.
finder#lines([options])	Lines	List buffer lines.
finder#matches(pattern, [options])	Matches pattern	List buffer matches.

Where pattern is the vim pattern (:help pattern) and options is an optional
Dictionary. Here is common and mode-specific options.

options

Option	Type	Default	Description
openBufferCommand	String	enew	Is used to open new buffer. One of the list [enew, new, vnew, tabe]
bufferName	String	finder	Title for the tabline.
prompt	String	>	Text is shown near the query.
startWith	String		Prepend query with given string.
handler	Funcref	function("finder#handler")	Do some job with selected item.
limit	Number	100	Maximum amount of occurrences.
finder	Funcref	function("finder#getMatches")	Returns List of matched items.
header	List	see code	Block of text shown at the top of the buffer. To hide, pass empty List.
comparator	Funcref	v:null	Is passed to vim sort function. To disable sorting, pass non-Funcref value.
grepCommand	String	grep -ni -m %i %%s	GNU grep pattern used for searching. Used for default finder.
headerContainedGroups	List	[]	List of additional contained syntax groups in the header. Useful when you want to define custom syntax highlighting for the header.
syntaxMatchRegion	String	^.+	Syntax region where matches should be highlighted. For instance, useful to restrict the highlighting only for basename part.

finder#files

Option	Type	Default	Description
directory	String	.	Directory to search in.
command	String	find %s -type f	Unix find pattern.
ignoredPaths	List	["*/.git/*", "*/.svn/*"]	List of strings are passed to ! -path flag.
baseName	Boolean	1	Whether or not use basename instead of full path.

Note: there are no shortcuts like <C-v> and <C-x> to open file in
splitted window. You should firstly open one with :new or :vnew command
and then execute :Files command. It is also possible to execute :Files . vnew

1. To toggle basename mode use <C-b>.

finder#tags

Option	Type	Default	Description
command	String	ctags -x --sort=no --format=2 --language-force=%s %s	Exuberant ctags pattern.
showPreview	Boolean	1	Focus tag while navigating.

finder#lines

Option	Type	Default	Description
showPreview	Boolean	1	Focus line while navigating.

finder#matches

Option	Type	Default	Description
offsetType	Number	2	Specify from which position the next match should be looked for in the string. 1 - after the start of previous match, 2 - after the end.
showPreview	Boolean	1	Focus match while navigating.

Examples

:call finder#files({"openBufferCommand": "tabe"})
:call finder#matches('function! \zs.\{-}\ze(')

Extending

You are free to add your own extensions. To do this, simply call
finder#custom(items, [options]) or finder#splitted(items, [options])

1. The first one is the base that all functions are "inherited" from.
   The second is useful when you work with the data in the buffer and, probably,

want to see a preview while navigating. items is a List of Dictionaries.
Dictionary should contain at least raw key. finder#splitted also requires
item.position that is a List of two elements: line and column where item
is placed in the buffer.

items

Key	Type	Required	Default	Description
raw	String	Yes		Used to make search.
visibleLine	String	No	raw	Used to show in the buffer.
comment	String	No		Used to show to the right of the visibleLine.

Events

Event	Description
FinderCancelled	Triggered when <Esc> has been pressed.
FinderItemSelected	Triggered when new item has been selected.

Example

function! ListFiles(...)
    let options = get(a:, 1, {})
    let options.prompt = "Files> "
    let options.openBufferCommand = "tabe"
    let options.handler = function("OpenFile")

    let items = []
    let files = systemlist("find . -type f")

    if(len(files) == 0)
        return finder#error("There are no files in this directory.")
    endif

    for file in files
        let item = {}
        let item.raw = file
        " You probably want to add something else to this dictionary.

        call add(items, item)
    endfor

    call finder#custom(items, options)
endfunction

function! OpenFile(item)
    execute printf("edit %s", fnameescape(a:item.raw))
endfunction

When <CR> or <C-o> has been pressed, OpenFile function will be called
and the selected item will be passed to the handler.

header

function! ListFiles(...)
    let options = get(a:, 1, {})
    let options.header = [
        \ repeat("=", 17),
        \ "Foobar: {foobar}",
        \ repeat("=", 17),
    \ ]

    " create items list
    let items ...

    call finder#init(items, options)

    let b:foobar = "some value"

    call finder#fill()
endfunction

String wrapped with {} is a variable. Finder parses all strings in header,
find variables and fill them with appropriate buffer variables. That is why in
this example we do not use finder#custom function, because it also includes
header rendering and since there is no b:foobar variable we need firstly
create a buffer, assign variable and then call finder#fill function.
Then you can change b:foobar as much as you want. Do not forget to call
finder#updateHeader after resetting value. Of course, if you need not complex
logic it is more rational to use static text. You also can overload
finder#getHeader function in your .vimrc to apply new header globally.

Default header uses b:matchesAmount and b:itemsAmount. You can use them too
and all other buffer variables defined by default. You can list all buffer
variables typing :echo b: and pressing <Tab>. Of course, you can simply
open the source code.
