I would like to display imenu content in Emacs Speedbar. Best as a flat list (like in with imenus) (not a tree-like structure).
In speedbar - Display menu I have only the following options:
Files
Quick Buffers
Buffers
Info
Eieio
Analyze (only after calling semantic-speedbar-analysis)
I wrote this for myself so there is no documentation, but all you should have to do is put it somewhere in your load-path and:
(require 'sb-imenu)
Start speedbar and choose the sb-imenu display.

I have a growing set of org files stored in org-directory. How can I navigate between them, preferably with interactive filtering and completion?
I thought there was a way to get org-mode to produce a list of known org files for quick navigation, but I can't seem to find it. If org-mode does not have this feature, how can I make a simple command that launches something like helm or icicles to find them?
The question is not very clear to me. But if your Org-mode files all have a certain file-name pattern (e.g. *.org) and all are in the same directory (org-directory) then you can use several methods Emacs method to access them:
C-x C-f *.org RETURN in org-directory opens them all (the buffers are visiting them but only the last one is shown).
C-x C-f *.org TAB in org-directory, to show them using completion, then pick whichever one you want (or pick more than one, using a glob pattern, as in #1).
The same as #2, using Icicles or Helm. In Icicles, at least, you can also match using regexps and in other ways.
Open Dired for just those files: C-x d *.org.
There are really any number of ways to do what you've described. But I'm guessing that you have not really described your request/problem/question well enough, and when you do you will get a narrower set of answers.
UPDATE after your comments:
Here's one way: Open Dired on all of your Org files in and under org-directory.
(defun foo ()
"Open Dired for (only) the Org files in and under `org-directory`."
(interactive)
(cd org-directory)
(dired "*.org" "-lRF"))
Test it with M-x foo. Put this in your init file:
(foo)
And here's another way: M-x bar or bind bar to a key.
(defun bar ()
"Open an Org file in or under `org-directory`."
(interactive)
(let ((default-directory org-directory)
(icicle-file-match-regexp ".*\\.org"))
(icicle-locate-file-of-content)))
I have a package that does just that: plain-org-wiki.
It's nothing too elaborate: I just dump all of my 45 org files into a single directory and get completion for them.
How about org-iswitchb, which is provided by org already?
Switch between Org buffers.
With one prefix argument, restrict available buffers to files.
With two prefix arguments, restrict available buffers to agenda files.
Add this to your startup file after org is loaded:
(global-set-key "\C-cb" 'org-iswitchb)
My favorite solution to this is helm-mode which is activated with the helm package from MELPA. Here's a demo:
It really makes for a great environment for searching ones files quickly. In addition, one can enable fuzzy completion! Here's a minimal configuration (after installing the helm package):
(require 'helm-config)
(helm-mode 1)
(global-set-key (kbd "C-x C-f") 'helm-find-files)
You can also run grep on the files if you'd like to search their content. Take a look at this amazing guide if you'd like to learn more.
I use sr-speedbar in emacs. On loading, it starts in file mode. I then manually change it to buffers mode. Since I almost always use buffers mode, I would prefer to start it in that. However, I cannot find any way after googling and wondering if someone with Lisp expertise has inputs on how to resolve this
The variable speedbar-initial-expansion-list-name controls the initial view of speedbar. The default value is "files". The other two possibilities are "quick buffers" or "buffers" -- either of the following could be placed in the .emacs file after a (require 'speedbar) statement:
(setq speedbar-initial-expansion-list-name "quick buffers")
or
(setq speedbar-initial-expansion-list-name "buffers")
The sr-speedbar is a package built on speedbar, so you need to consider customizing speedbar itself as well. There is no existing customization option for what you want but you can implement youself by using Hook, in your case, speedbar-mode-hook.
The following should do what you want
(add-hook 'speedbar-mode-hook
(lambda ()
(speedbar-change-initial-expansion-list "quick buffers")))
I copy it from https://stackoverflow.com/a/24291661/2999892 and I've test it by using both speedbar and sr-speedbar.
I am currently trying to learn Emacs more in depth so that I can do more with my Emacs than just simple editing stuff...
I am making good progress and at the moment I am trying to configure the 'sr-speedbar' module to my liking, but some details I can't figure out myself:
Say that I've 2 open buffer windows A and B plus the speedbar window. If I open a file by pressing Enter in the speedbar window, then the new file always get opened in the same buffer window B (which I opened last). Can I somehow specify that the new content should be opened in buffer window A?
Currently the speedbar window refreshes itself automatically to the new location whenever I open a new file using 'C-x C-f'. This is actually pretty useful, but sometimes I don't want this when I am quickly trying things out in a tmp file. And the refresh also "destroys" my "tree-view" of the speedbar, where I expanded the directory contents rather than opening them directly. The question is, how can I suppress this "refreshing behaviour"? Can I somehow disable the automatic mode and trigger it manually if I need it?
And do you guys have more useful tips regarding speedbar navigation? How does a Emacs guru use speedbar or are there better alternatives?
Thx in advance for your help!
You can turn off the auto-refresh in your init file like this -
(require 'sr-speedbar)
(setq sr-speedbar-auto-refresh nil)
and/or turn it on and off later with the function sr-speedbar-refresh-toggle.
The defaults it (and speedbar) comes with are a bit odd though - it also doesn't show files that it doesn't recognize, uses images for buttons, and is set on the right side - so you can set these if you'd like -
(setq speedbar-show-unknown-files t) ; show all files
(setq speedbar-use-images nil) ; use text for buttons
(setq sr-speedbar-right-side nil) ; put on left side
I do use sr-speedbar for projects that have enough of a directory structure - otherwise I use the usual switch-to-buffer (C-x b), ibuffer (C-x C-b), and dired (C-x d), and another function that switches to the previous buffer. Also bound to single keys because they get used so much.
But... I'm still learning Emacs - I haven't tried helm, projectile, or project-explorer yet - they look interesting also.
I'm trying to use Emacs and everything is fine, but the information about every file in my directory is too comprehensive. How can I tell it to show only file name (and maybe filesize in human readable format)? I tried options like dired-listing-switches but without any luck.
As of Emacs 24.4, hit key (.
Repeated, this will hide/unhide details. This is part of Dired Details.
You can reduce the amount of information displayed by using Emacs' ls emulation instead of allowing it to use ls directly.
To enable ls emulation, add the following code to your startup file (probably .emacs or .emacs.d/init.el):
(require 'ls-lisp)
(setq ls-lisp-use-insert-directory-program nil)
You can then customise the display with M-x customize-group RET ls-lisp RET. Specifically, the "Ls Lisp Verbosity" setting can be used to disable a number of columns. There's no obvious way to get it down to just the filename and size, but you can certainly get rid of the owner/group/link-count columns.
Great news, a more efficient version of DiredDetails is in the master branch of Emacs now; it uses text properties instead of overlays..
I looked for it because DiredDetails' reliance on overlays made it too slow for one find-dired result set.
I'm not sure if it'll be in 24.3 or 24.4. Get the raw file here: http://git.savannah.gnu.org/cgit/emacs.git/plain/lisp/dired.el
also, to show file sizes in human-readable format (kB/MB), add this to your .emacs:
(setq-default dired-listing-switches "-alh")
Yesterday I installed ECB on my Emacs, and I find method window and history window quite useful. But directory tree window and source window less useful, if I can hide them I will save more space for method window and history.
Another problem is that I use cscope to search through the project for definitions and callers, the result of cscope is shown by splitting the main window into two. I'd like to know is it possible to make cscope result window fixed in ECB window, just like method window and history window?
Many thanks.
===============
Thanks to sanityinc and ecb documents, finally I create a layout with cscope fixed in it. I'll post code here in case it will help others.
(require 'ecb)
(ecb-layout-define "my-cscope-layout" left nil
(ecb-set-methods-buffer)
(ecb-split-ver 0.5 t)
(other-window 1)
(ecb-set-history-buffer)
(ecb-split-ver 0.25 t)
(other-window 1)
(ecb-set-cscope-buffer))
(defecb-window-dedicator ecb-set-cscope-buffer " *ECB cscope-buf*"
(switch-to-buffer "*cscope*"))
(setq ecb-layout-name "my-cscope-layout")
;; Disable buckets so that history buffer can display more entries
(setq ecb-history-make-buckets 'never)
There are a bunch of layout presets, listed here, one of which might work for you. Also, you can create a custom layout following the directions here, which can even be done interactively using the ecb-create-new-layout command.
The latter page also describes how to add a new fixed window, of the type you want for cscope.
