I added narrow-ui:fold:increase-fold-level, narrow-ui:fold:decrease-fold-level in #24.

But this concept should not necessarily limited to fold.
For narrow:line, each line have indent level.
For markdown text, number of preceding # can be considered as level.

So I'm thinking about cmd-], cmd-[ to map on narrow:ui to

• cmd-[: narrow-ui:decrewase-level to show less items
• cmd-]: narrow-ui:increase-level to show more items

Each provider can control what the level means on each provider by overriding getLevelForItem.
By default(without overriding), getLevelForItem should be determined by indent level of that row.

getLevelForItem: (item) ->
  row = point.row
  @editor.indentationForBufferRow(row)

Items are filtered by using that level number

Not sure if it's really useful, will see after evaluating!

caught myself reaching for escape a couple times to close the narrow editor, so this would be lovely:

'atom-text-editor.narrow[data-grammar="source narrow"]':
  'escape': 'core:close'

Hi - just trying out your alpha version. This is something I would love to have, thanks for your work !

This is what you are trying to do, right ? https://github.com/ShingoFukuyama/helm-swoop
That would be awesome.

Narrow: Search and then j/k ... then Narrow UI: Reveal Item kind of works to get something like helm-swoop.

I tried it with auto-reveal. It would be nice if it selects the line too.

I don't want to file a specific bug because I'm sure you know what to work on next.

Just offering encouragement !

Looking forward to updates !

Problem

I sometimes hit this bad situation, as far as I can say, it's when I use search provider and work around narrow-items on narrow-ui with autoPreview on.
So open multiple files for previewing, then some of opened editor have remained highlight.

Expected behavior

Must destroy hl decoration without any exception

• Pros

  • Easier to correspond narrowEditor's text to underlying editor's text.
  • When introduce inline-edit feature(Update bounded-editor's text by editing narrowEditor.)

• Cons

  • When copying, no longer copy rows(possibly, sometimes useful to share row info to other person).

Currently feature/behavior is VERY fluctuating so current default keymap is not settled yet.

See also "Use case and flow of keystrokes" #75

Will put idea and WANT/DONT_WANT list on this issue to discuss about reasonable default-keymap.

• #48 to map escape to close narrow-editor

1. Do Narrow:fold on a file
2. Select, closing narrow window
3. Do other things
4. Go back to the same pane that was narrowed
5. Save
6. This error thrown each time

Even if you shut the file and repoen it, the memory still has the narrow view cached.

ありがとうございました !

Again. great plugin! =)

I have the habit of accidentally using cmd-a + delete rather than cmd-delete. The former accidentally clears the narrow pane's content and goes into a weird state. I think I override this behavior myself but I was wondering if it's worth making narrow a bit safer regarding arbitrary modifications?

Or, better idea: editing narrow's buffer, and make the change reflect in the original editor! No need to jump to place, modify, then jump back! =D

So like the title says, I get the observeVimStates is not a function error whenever I startup Atom. I thought it was a problem with vmp but noticed that the error only happens if I have narrow installed.

Here's the stack trace and related info copied from Atom:

No dev packages

Currently narrow:search depending on ag external commands.
Evaluate if I can use scandal for as replacement.

Benefit

• No dependency of external binary commands(maybe good for less not-working issue in windows?). #9
• No special translation is required for regex in Js and regex for ag.
  • This make easier to support more narrow query varieties
    • Regex search
    • Regex escape search
    • Ignore case/word boundary search
    • Custom sugared query like !abc to reject abc item.

e.g. ctrl-cmd-n move-down on narrow-buffer, ctrl-cmd-p move-up on narrow-buffer

Situation.

1. I edited text-object.coffee, which file include multiple classes, each class have select: -> method.
2. I wanted to add some code at last line of select() body.
3. So invoke fold, then input select:, which shows only select: -> lines, these are the target I'll editing from now
4. So I go to first select: then enter insert-mode and edit
5. WAIT! I want to keep editing, don't want to change focus to narrow, but dont want to consult native cmd-f(find-and-replace) or cmd-r(symbols-view), just want to use narrow to move my cursor to next select body.

If occurrence-marker of vim-mode-plus was exists at the timing of starting narrow:lines,
Pick it as initial pattern of narrow-input

I'm not sure if it really useful or I can implement it in very intuitive way.
So let's try and evaluate it.

What's inline-edit?

• User can directly edit narrowEditor.
• When saved it reflect changes to corresponding buffer disk.
• e.g. narrow:search then editor narrowEditor directly, save it, DONE.
• Support delete whole line.

This enhancement require BIG change. So need to move forward step-by-step.

• Show line number on gutter
  • By this enahancement I can easily map text on narrowEditor to line on actual-buffer without translation
  • If line numbers are exist, I need to trim that part to correspond to line on actual-buffer.
• Show file header on block decoration
  • This is same reason. To make file header free from mutation.
  • I once evaluated and worked, but removed in favor of intuitiveness.
• Why above steps is required? Because I don't want to open another editor to start inline-edit.
• Separate query-input-area from items listing editor?
  • To support more rich indicator for case-sensitivity, regex/regex-escaped status etc..

After re-thinking, I'll take shortest-path, thus introduce direct-edit WITHOUT introducing big change to current narrowEditor.

• Just refrect change in narrowEditor by translating line by triming row:column part.

Just hit enter in narrow pane

caseSensitivityForNarrowQuery config options

possible values are

• smartcase( default )
• sensitive
• insensitive

Spec

• Providers global(not per provider value at this point).
• User can chain multiple query by separating query by white-space.
  • So, in smartcase, case sensitivity is handled by per word(separated by white-space)
  • Eg. For query "word Case", first word is ignoreCase, 2nd Case is NOT ignoreCase.

After success of 1st single edit of direct-edit, re-editing then update-real-file do nothing.
Investigate and fix it.
Maybe because of listed item's state(text field) not reflecting update done by direct-edit.

I haven't found a case where I'd like auto preview to be off by default, actually. So I usually do narrow:search-current-project then toggle on auto preview myself.

The one case I can think of is when the file is too huge and you wouldn't want the toggle to be on; that's been rare for me though.

In narrow/styles/main.less:

Starting from Atom v1.13.0, the contents of atom-text-editor elements are no longer encapsulated within a shadow DOM boundary. This means you should stop using :host and ::shadow pseudo-selectors, and prepend all your syntax selectors with syntax--. To prevent breakage with existing style sheets, Atom will automatically upgrade the following selectors:

• atom-text-editor::shadow .narrow-ui-row => atom-text-editor.editor .narrow-ui-row

• atom-text-editor .narrow-match .region, atom-text-editor::shadow .narrow-match .region => atom-text-editor .narrow-match .region, atom-text-editor.editor .narrow-match .region

• atom-text-editor .narrow-flash .region, atom-text-editor::shadow .narrow-flash .region => atom-text-editor .narrow-flash .region, atom-text-editor.editor .narrow-flash .region

• atom-text-editor .narrow-result .region, atom-text-editor::shadow .narrow-result .region => atom-text-editor .narrow-result .region, atom-text-editor.editor .narrow-result .region

• atom-text-editor .line.narrow-result, atom-text-editor::shadow .line.narrow-result => atom-text-editor .line.narrow-result, atom-text-editor.editor .line.narrow-result

Automatic translation of selectors will be removed in a few release cycles to minimize startup time. Please, make sure to upgrade the above selectors as soon as possible.

Relatively big project like atom/core source and search editor then narrow something results multiple same file header displayed.

"Automatically removed from your connfig.cson "

should be config.cson.

Thanks for all your hard work!

When i select narrow line focus not in work-pane

Currently, atom-scan and search provider use mini input form to read user-input.
Which input is passed to ag or atom.workspace.scan.

But Is it necessary?
Let's evaluate use narrowEditor for this purpose.

What will change.

• narrowEditor(ui)'s first query keyword is treated as search-term(passed to ag)
• Benefit is: Whenever user re-search in different keyword, user can directly edit it.
• narrowEditor will be opened BEFORE user specifying search-term.
  • Good for internal code consistency.
  • Good for easily restorable full-state of narrow-editor.

Sometime I want keep fold narrow-buffer open, don't want to accidentally close by enter and re-invoke narrow:fold.

After I start a narrow-search or narrow-search-current-project, a empty pane named search is opened, then nothing. Check the system, the ag process is there and never exit itself. Do you have any suggestion to debug this issue? Thanks.

to show narrow result in different fold levels

@t9md what do you think?

Related: #6

This is a line highlighted by narrow:

Notice that currently, I have a region selected. You can't see it because narrow's highlight is of the same color.

show ui first and then incrementally add items onData arrives
This was original behavior I first implemented, but removed for simplify overhaul make easier

Not a bug report, just a comment/Idea.

I've run narrow: line on an existing narrow buffer. Works as intended =D. There's some potential here!

The use-case was to narrow down on foo and see if there's any bar on the same line. I search for foo first then open narrow: line on the narrow buffer to search for bar, then jump and jump back to the original code).

Maybe there can be first-class support of this, or maybe it doesn't need one for now.

Also, it'd be great to see the context around a line, e.g. some shortcut to expand around the line (and heck, edit in-place!)

Very critical bug.
Simplify it, eliminate caching approach until it become really necessary.

I was untouched after initial intensive development of this package.
Now I'll begin to use this package and want to re-think how I can improve this package.

Here is the recap of history and also planning features.

Terms & Roles

• narrow-editor: The text-editor where you see candidates and narrow down by input.
• candidates: Items shown on narrow-editor.
• actions: Action to be taken when you enter. As like helm is doing, tab to select alternate action? (not implemented yet)
• provider: Provide candidate via getCandidate(), and take action via confirm().
• narrow-ui: Provide basic navigation on narrow-editor, > indicator, narrow-input area at top of narrow-editor, all handled by narrow-ui.

Things to consider

• vim-mode-plus integration: As a maintainer and heavy user of vim-mode-plus, I always prioritize better integration with vim-mode-plus.

What I'm thinking or design decision

CAUTION: Atom already have command-palette.

I should always ask to myself that "Is that important? I really need this? Can't I use regular command-palette for that?"

FINISHED: narrow-editor has to be normal text-editor

I once tried block-decoration to show the matched file names but removed this feature.

231f733

Part of it was good, but blending non-text-editor block into regular text-editor tend to confuse user and could not stand the issue which prevent me to use normal-text-editor keybinding.

IDEA: Keep it stupidly simple

anything.el, helm.el, unite.vim was(is) big.
Rather than trying to match(or beat) it, I want make narrow stupidly simple than these counter part.

I don't want to maintain big code base which is complicated because of huge feature base.
I have no resources or skill to maintain such a big ones.
Want to make it easy to create provider.
When I'm not sure, let provider do everything, duplication of codes in each provider is not bad when compared to trying to do everything by core side and limit what provider can do.

IDEA: Extensibility

As like autocomplete-plus accept provider package which provide candidates to complete for specific language.
I want narrow accept 3rd party package which provides narrow candidate and also allow provider decide what-to-do when candidate confirmed.

Thus allow broad user to create narrow-xxx packages as separate package.
There is bunch of examples for emacs-helm, vim-ctrlP and vim-unite(or denite as successor).

Here is example packages I can imagine quickly.

• narrow:outline: Improved version of narrow:fold, show header for markdown buffer.
• narrow:shell-command: Execute shell command background or send command to tmux's window? not sure..
• narrow:symbols: To collect candidate, use atom's syntax symbol. Variables, module import, function are displayed ordered.
• narrow:book-marks: Just use atom's bookmarks.
• narrow:projects: Add/remove project from specified directory? Simiplar to my atom-project package.
• narrow:git-grep: Kind of narrow:search, use git grep to collect candidate.
• narrow:recent-files: Open recently opened files.
• narrow:themes: Change theme quickly.
• narrow:diff: List the diff lines on buffer, across-buffer.

I don't want make all of these by myself(??), but I want to create easy-to-use interface and easy-to-understand fundamental for those packages.

Must to read

Rubichichi's introduction for helm: He is one of main anything.el and helm.el maintainer.
Unite.vim's help: Especially for how-to-create-unite plugins, I have created some of it in the past :)

Discussed in #17

provide following config option

• LinesDefaultAutoPreview
• SearchDefaultAutoPreview
• FoldDefaultAutoPreview

[NOTE] the effect of narrow-ui:toggle-auto-preview command is volatile not change this default value.

CC @chenglou

For more powerful way to narrow items on the list.
This is for how query keyword is treated in narrowEditor.

• Settled: Keyword is separated by #white-space.
  • Type of query(regex/simple-keyword) has to be treated per query-word.
• Settled: simple-keyword: Internally filtered by _.escapeRegExp
  • When no special prefix is used as query.
  • Case sensitivity(sensitive/insensitive/smartcase) is handled per query-word.
  • What if I want to search space itself or space contained keyword as simple-keyword?
    • No I can't, but maybe it's OK. Use regex \s.
  • Wild card helper support?
    • When I want to search keyword starting pre- keyword.
    • I can use * as wildcard.
    • e.g. pre-* matches pre-a, pre-abc etc..
    • e.g. pre-*llo*suffix matches pre-hello-worldsuffix etc.
    • Single * matches non-whitespace char(>1 length). abc*e not matches abe.
    • What if I want to search * itself? Doesn't * helper disturbing?
      • Double **.
• Idea: negate-simple-keyword
• Idea: regex: by prefixing query with /, e.g. /abc\w+
  • When I want to search / char as simple-keyword, doubling /
    • So searching /etc/hosts as simple-keyword would be //etc/hosts(yes second / is not necessary).
• Idea: negate-regex: by prefixing query with !/. e.g. !/abc\w+
  • When I want to search !/ char as simple-keyword, doubling //
    • So searching !/etc/hosts as simple-keyword would be !//etc/hosts(yes second / is not necessary).
• Idea: Provide short cut to replace type of keywods?
  • narrow-ui:toggle-negate-query add/remove ! prefix of current-word.
  • narrow-ui:toggle-regex-query add/remove / prefix of current-word.
• Idea: Syntax highlight(by grammar) to help understand meta char or regex/not-regex status by eye.
  • e.g. Single * is highlighted, but ** is not highlighted.

Hi, @t9md

What is your plan for this project? Do you still use it? I have some plugin ideas. Can you write a simple guide for writing plugins? Thanks.

reloading HTML custom element throw error, so workaround this as like I'm doing in vmp.

It's highlight is not correct and difficult to render correctly to translate fuzzy pattern into highlight regex.

Remove this confusing feature in the meantime.

Like project-find:search-under-cursor, this would open a narrow:search (ag) for the word under the cursor. I usually have this bound to ctrl-/

So the workflow would be ctrl-/ ... j j j ENTER

Which would be my new favorite way to navigate from my brain to the code I'm trying to find.

new update looks great !

narrow lines isn't quite working for me. It doesn't filter right now.
