Re: Is there a way to enter occur-edit-mode (or it's equivalent) from helm-occur?

Thierry Volpiatto — 2013-04-17T04:47:40


No, it is not implemented because we have grep that is already doing
this.

So you have to install:

https://github.com/mhayashi1120/Emacs-wgrep.git

and while in a helm grep session hit C-x C-s to save the helm buffer and
enter `helm-grep-mode', from there you have access to
`wgrep-change-to-wgrep-mode' (C-c C-p)

Of course it could be implemented for helm-occur in the same way, using
wgrep.


You should not do that.

Is there a way to enter occur-edit-mode (or it's equivalent) from helm-occur?

Alex Bennée — 2013-04-17T03:16:02

Subject says it all really. Once I've narrowed down my occur search I'd 
like to be able to edit the buffer. Although C-x o does bring me to the 
helm-occur buffer the default keybindings mean I can't edit it.

Ok, when I will know exactly what is needed, we could allow enabling
such sorting at the helm core level instead of running extra loop ect...

It's easier to discuss once I have some working code.  The key problem I'm

important.  So I need to sort the items in order of importance before the

Sorry but I have not enough informations to figure out what you are
trying to do exactly.
 

If you add a new function (flex) to a match attribute:

(defvar helm-source-test
  '((name . "test")
    (....)
    (match . flex)))

this flex function will run and then all the other match-plugin
functions unless you use `match-strict` instead of match.

Actually I must sort in the candidate-transformer, correct?  I only want to

It looks like the easiest way to do this is to make a new match method in
helm-match-plugin.  The idea is that I want the first word of the pattern
to be "flex" matched, but the following words should work the same as
"multi3p".  What do you think about that?

Re: Experimenting with a custom matcher, sorter, and highlighter

Thierry Volpiatto — 2013-04-14T18:17:47


The match function should only match against candidates, sorting and
highlighting should happen in filtered-candidate-transformer or
candidate-transformer. 



Yes.


Just sort and highlight in filtered-candidate-transformer, see above.

Re: Experimenting with a custom matcher, sorter, and highlighter

Le Wang — 2013-04-14T12:46:59

I may be missing something, but the flow is not clear to me.

I have a match function that's quite complicated, it returns information on
how to sort and highlight the match.  As it stands it looks like the
"match" function gets a candidate as a string and returns non-nil when it's
matched.

I don't want to recalculate the match information when I do the sorting and
highlighting in the "filtered-candidate-transformer"?

Hi Le,

Le Wang <l26wang-Re5JQEeQqe8AvxtiuMwx3w< at >public.gmane.org> writes:


Normally, `matching` functions are for use with `candidates`
implementation of a source, and 'searching' for `candidates-in-buffer`,
this have limitations for `candidates-in-buffer` actually.
But in this case the both can be used, 
see how I recently did in helm-bookmark.el, you will find the both
methods.

For a matching function, see in helm-buffers.el
`helm-buffer-match-major-mode`.

For highligthting, you will find filter functions in many places,
including the ones cited above.

For sorting see in helm-sys.el how top is sorted by CPU, MEM etc..


I suggest you implement this with an attribute by source, adding this
attribute e.g (flexmatching) to a source would enable this matching
method in this source only.

Experimenting with a custom matcher, sorter, and highlighter

Le Wang — 2013-04-13T15:50:26

Hi Thierry,

I'd like to play around with a custom matching function, and a custom
sorting function and a custom highlighter.  Is there a good example of this?

This is for an implementation of flex that I'm playing around with.

Can you make helm matching algorithm behave like Vim's command-t ?

2013-03-26T05:07:50


Let's say you have two paths:

   - app/controllers/admin/feedback_controller.rb
   - app/controllers/fee_controller.rb

In Vim's command-t, you can write:

"app/controllers/fe"

And it will match both paths.

On helm-cmd-t, if I write "app/controllers/fee", it will only match 
"fee_controller". If I want to match both, I have to use a regexp, as in 
"app/controllers/.*, which is not that bad, but requires more keystrokes.

Is there a way to make helm/helm-cmd-t's matching algorithm behave 
similarly to command-t's one?

Cheers!

Marcelo.

Re: Any way to have helm-find-files only show file names? (and not the entire path)

Thierry Volpiatto — 2013-03-02T16:52:53

It is now the default (non--nil), so you can remove the 

(setq helm-ff-transformer-show-only-basename t)

from your config.

(setq helm-ff-transformer-show-only-basename t)

And during your helm-find-files session, hit `C-]' to toggle full path.

Any way to have helm-find-files only show file names? (and not the entire path)

Ribonous — 2013-03-01T21:42:01

helm-find-files shows a list of files with the full path of each file. If I 
am deep down in a directory, the list can be hard to read. Is there any way 
to see this list without the full paths behind the file names? (I can 
always read the path where I am currently in the mini-buffer)

Thanks!

show buffer in anther window and jump to function under the cursor

Tommy Huang — 2013-02-17T15:22:23

1. I am using semantic-ia-fast-jump and semantic-mrub-switch-tags to jump 
back and forth to the function definition under the cursor. Now I am trying 
to switch to use helm + etags. 
However, I don't know how to set the config to jump back and forth the 
etags under the cursor. Is there any command that I can bind to?

2. When using grep or show tag lists, another window is used to show the 
content of  the current highlighted tags/grep results. 
However, in helm, I have to type C-z  C-z to show it in anther window, it's 
quite inconvenient. I would like another window changes its content when I 
browse through the tag/grep results. 
Is there any way to do that?
Thanks.
