*eclimd*
The Eclim Daemon
****************
*eclimd-headless*
Headless eclipse server
=======================
The most mature usage scenario that eclim provides, is the running of
a headless eclipse server and communicating with that server inside of
vim. Starting and stopping of the headless eclipse instance is
detailed below.
Starting eclimd
Linux / Mac / BSD (and other unix based systems): To start eclimd from
linux, simply execute the eclimd script found in your eclipse root
directory: $ECLIPSE_HOME/eclimd
Note: When starting the eclim daemon, you must start it as the same
user who will be running vim.
Windows: The easiest way to start eclimd in windows is to double click
on the eclimd.bat file found in your eclipse root directory:
%ECLIPSE_HOME%/eclimd.bat
Note: Even though an eclipse gui is not started in eclim's headless
mode, eclipse still requires a running X server to function. To run
eclimd on a truely headless server, please see the headless guide
(|install-headless|).
Stopping eclimd
To cleanly shutdown eclim use any one of the following.
- From Vim:
>
:ShutdownEclim
<
- From a console:
>
$ $ECLIPSE_HOME/eclim -command shutdown
<
- Lastly you can use Ctrl-C at the console if you are running eclimd
in the foreground, or issue a kill to the eclimd java process.
>
$ kill *pid*
<
You will need to kill the java process since killing the eclimd or
eclipse process will not do so. While eclim provides a shutdown
hook to support a clean shutdown when the java process is killed in
this manner, it is still recommended that you utilize one of the
first two methods instead, and reserve this as a last resort. Also
note that when killing the java process eclipse will pop up an alert
dialog notifying you that the java process was terminated underneath
it. This is nothing to be alarmed about.
*eclimd-headed*
Headed eclipse server
=====================
For users that find themselves periodically needing the eclipse gui,
or otherwise wanting to keep the gui open while using eclim, there is
support for running the eclim server inside of a headed eclipse
instance.
Starting eclimd
The eclim daemon inside of eclipse is implemented as an eclipse view
which can be found via:
Window ‣ Show View ‣ Other ‣ Eclim ‣ eclimd
The view will be opened in a new tab in the same pane as the
"Problems" tab, as shown below.
[image]
Note: By default, if you open an instance of gvim from within
eclipse, the eclimd view will be opened for you if necessary. This
behavior is configurable via the Vimplugin preferences.
Stopping eclimd
As long as the eclimd tab is open then the eclim daemon will be
running. Stopping the eclim daemon is just a matter of closing the
eclimd tab. Also note that leaving the tab open and closing eclipse
will shutdown the daemon as well, and on the next start of eclipse the
tab will be opened, but the eclim daemon will not start until the tab
is forced to display itself. In other words, the daemon will not start
until the eclimd tab is the active tab in that group.
*gvim-embedded*
Embedded gvim
=============
Note: Embedding is only supported on Windows and Unix systems (where
gvim is compiled with the gtk gui).Embedding of macvim for OSX is
not supported since macvim does not currently have the ability to be
embedded like gvim. Macvim can still be used to open files from
eclipse, but macvim will open as an external editor. Also note that
macvim snapshots 56 through 63 contain a bug
(https://github.com/b4winckler/macvim/pull/22) where opening a file
from eclipse will open an instance of macvim, but the file will not
be loaded into that instance.
Another feature provided by eclim for those who prefer to work inside
of the eclipse gui, is the embedding of gvim inside of eclipse. This
feature is provided by an eclim local fork of vimplugin
(http://vimplugin.org). The feature adds a new editor to eclipse
which allows you to open files in gvim by right clicking the file name
in the eclipse tree and then selecting:
Open With ‣ Vim
[image]
Please note that if you want to use supported eclipse features (code
completion, validation, searching, etc.) from the embedded gvim
editor, you must have the eclimd view open.
Note: If you'd like to have the embedded gvim editor as the default
for one or more file types, you can configure it to be in your
eclipse preferences:Window ‣ Preferences ‣ General ‣ Editors ‣ File
Associations
The eclim installer should take care of locating your gvim
installation for use inside of eclipse, but in the event that it could
not locate it, you can set the location and other settings via the
vimplugin preferences:
Window ‣ Preferences ‣ Vimplugin
For MacVim users on OSX, the eclim installer will attempt to locate
MacVim's mvim script on your path. If it's not found you can set the
location of that script in the Vimplugin preferences:
Eclipse ‣ Preferences ‣ Vimplugin
Note: If you have a non-eclim version of vimplugin installed you
should remove it prior to using the eclim version.
Note: Some users have reported issues with the embedded gvim's
command line being cut off or possible rendering issues when
scrolling through the file. If you experience either of these
issues, try adding the following to your vimrc file, which should
hopefully resolve those problems:>
set guioptions-=m " turn off menu bar
set guioptions-=T " turn off toolbar
<
Additionally, some users have reported that gvim's left scrollbar
may also need to be disabled:>
set guioptions-=L " turn off left scrollbar
set guioptions-=l
<
*eclim-gvim-embedded-focus*
Embedded gvim focus
In some windowing environments, the embedded gvim is treated more like
a separate window. The result of this is that clicking the eclipse tab
(or using tab focusing keyboard shortcuts) may focus that tab, but it
won't focus the embedded gvim on that tab. Eclim adds a setting to
vimplugin which when enabled, will attempt to simulate a click on the
embedded gvim window to force it to focus:
Window ‣ Preferences ‣ Vimplugin ‣ Force gvim focus via automated
click
*eclim-gvim-embedded-shortcuts*
Eclipse/Vim key shortcuts in embedded gvim
Depending on your OS and windowing system, when the embedded gvim has
focus, you will fall into one of two groups:
1. In the first group of users, all key presses are received by
eclipse prior to sending them to gvim.
For this group, when typing a possible key shortcut (ctrl-n for
example), eclipse will first evaluate that key stroke to see if
there are any eclipse key bindings registered. If there are, then
eclipse will run the associated command and the key stroke is never
sent to gvim. If no key binding is found, then eclipse will pass
the key stroke through to gvim. What this means for you is that
for any gvim key mappings that you use that have an eclipse key
binding, they will not be evaluated inside of gvim. So, if you
encounter this issue, you'll need to remap the keys in vim or
eclipse. To remove the key binding from the eclipse side, simply
open the "Keys" preferences page:
Window ‣ Preferences ‣ General ‣ Keys
Then find the entry in the list that corresponds with the key
binding you want to remove, select it, and hit the "Unbind Command"
button.
Note: By default eclim will auto-remove a couple of the standard
eclipse bindings whenever an embedded gvim editor has focus and
then restore them with a non-gvim editor gains focus:
- Ctrl+U: in eclipse this runs "Execute", but in gvim this is
needed to run code completion (ex. ctrl-x ctrl-u).
- Ctrl+N: in eclipse this runs the "New" wizard, but in gvim
this is also needed as a part of code completion, to scroll
through the results.
- Ctrl+V: in eclipse this pastes text from the clipboard
(though not into gvim), but in gvim this is needed for column
wise visual selections.
- Ctrl+W: in eclipse this closes a tab, but in gvim this is
needed to switch windows (ex. ctrl-w j).
- Ctrl+X: in eclipse this cuts a selection to the clipboard,
but in gvim this is needed to start various insert completions
(ex. ctrl-x ctrl-u).
- Delete: prevent the eclipse delete key binding from
suppressing delete attempts in the embedded gvim.
*FeedKeys*
2. In the second group, all key presses are received by gvim and
not evaluated at all by eclipse.
For this group of users, you may have an eclipse key shortcut that
you like to use (Shift+Ctrl+R for example), but when you hit that
key combination, it will be evaluated by gvim instead of eclipse.
To remedy this situation, eclim provides a means to map eclipse
shortcuts inside of gvim. To register a shortcut, simply add your
mappings to your vimrc, gvimrc, or other standard gvim file like
so:
>
" maps Ctrl-F6 to eclipse's Ctrl-F6 key binding (switch editors)
nmap <silent> <c-f6> :call eclim#vimplugin#FeedKeys('Ctrl+F6')<cr>
" maps Ctrl-F7 to eclipse's Ctrl-F7 key binding (switch views)
nmap <silent> <c-f7> :call eclim#vimplugin#FeedKeys('Ctrl+F7')<cr>
" maps Ctrl-F to eclipse's Ctrl-Shift-R key binding (find resource)
nmap <silent> <c-f> :call eclim#vimplugin#FeedKeys('Ctrl+Shift+R')<cr>
" maps Ctrl-M to eclipse's Ctrl-M binding to maximize the editor
nmap <silent> <c-m> :call eclim#vimplugin#FeedKeys('Ctrl+M', 1)<cr>
<
The value supplied to the FeedKeys function must be an eclipse
compatible key binding string as found in:
Windows ‣ Preferences ‣ General ‣ Keys
Be sure to notice the extra argument to the FeedKeys function in
the last mapping. Supplying 1 as the arg will result in the
refocusing of gvim after the eclipse key binding has been executed.
*eclimrc*
~/.eclimrc
==========
On unix platforms (linux, mac, bsd) eclim supports an optional
.eclimrc file located in your home directory. In this file you may
supply any system properties or vm args which you would like passed to
eclimd at startup. The format of this file is the same as the
standard java properties file format with the exception of any vm args
which you would like to include.
Ex.
>
# Bind eclimd to all interfaces
nailgun.server.host=0.0.0.0
# Specifies the port that nailgun / eclimd listens on for client requests.
nailgun.server.port=10012
# Specifies the workspace directory to use
# See $ECLIPSE_HOME/configuration/config.ini for other osgi properties.
osgi.instance.area.default=@user.home/myworkspace
# increase heap size
-Xmx256M
# increase perm gen size
-XX:PermSize=64m
-XX:MaxPermSize=128m
<
The eclim client will also utilize this file, but only to determine
the nailgun server port should you choose to change the default.
Note: Your system must have perl and sed available so that eclim can
process your .eclimrc file.
Both the eclim and eclimd scripts also support a -f argument allowing
you to specify an alternate location for your .eclimrc:
>
$ eclimd -f ~/.my_eclimrc
$ eclim -f ~/.my_eclimrc -command ping
<
eclimd logging
==============
Eclimd utilizes log4j for all of its logging. As such, the logging
can be configured via the
$ECLIPSE_HOME/plugins/org.eclim_version/log4j.xml file.
By default, eclimd writes all logging info to both the console and to
a log file in your workspace: <workspace>/eclimd.log
*eclimd-multiworkspace*
Multiple Workspaces
===================
Running eclim against more than one eclipse workspace can be
accomplished by running multiple eclimd instances. You must configure
each instance to run nailgun on a unique port and supply the path to
the workspace you which that instance to use. Once your eclimd
instances are up and running the vim client will automatically
determine which server to send requests to based on your context. In
some cases you may be prompted for which workspace to use if one
cannot be determined for you.
Below are some different ways in which you can configure your eclimd
instances:
1. All Users: Supply the nailgun port and eclipse workspace path
when starting eclimd:
>
$ eclimd -Dosgi.instance.area.default=@user.home/workspace1 -Dnailgun.server.port=9091
$ eclimd -Dosgi.instance.area.default=@user.home/workspace2 -Dnailgun.server.port=9092
<
If you are using the eclimd view in the eclipse gui, then you can
start the eclipse gui with the desired nailgun server port (note
that you must place the -vmargs option before the list of jvm
arguments):
>
$ eclipse -vmargs -Dnailgun.server.port=9092
<
2. Linux, OSX, BSD Users: Specify the port and workspace in eclimrc
files and start eclimd with the -f or --file argument:
>
$ vim ~/.eclimrc1
osgi.instance.area.default=@user.home/workspace1
nailgun.server.port=9091
$ vim ~/.eclimrc2
osgi.instance.area.default=@user.home/workspace2
nailgun.server.port=9092
$ eclimd -f ~/.eclimrc1
$ eclimd --file ~/.eclimrc2
<
Note: The -f/--file argument is not supported by eclipse so the
above option is only available when using a headless eclimd
instance.
3. Windows Users: Create Windows shortcuts:
- In Windows Explorer, open your eclipse folder.
- Hold down the right mouse button and drag the eclimd.bat file
to where you want the shortcut to exist (like your desktop) and
release the right mouse button.
- Choose "Create Shortcut(s) Here"
- Right click the shortcut and choose "Properties"
- On the "Shortcut" tab edit the "Target:" field and append:
-Dosgi.instance.area.default=@user.home/workspace1
-Dnailgun.server.port=9091
- Repeat this process for your other workspaces.
*eclimd-extdir*
Hosting third party nailgun apps in eclimd
==========================================
Since nailgun provides a simple way to alleviate the startup cost of
the jvm, other projects utilize it as well. However, running several
nailgun servers isn't ideal, so eclim supports hosting other nailgun
apps via an ext dir where you can drop in jar files which will be made
available to eclim's nailgun server.
The ext dir that eclim reads from is located in your vim files
directory:
Linux / BSD / OSX:
>
~/.eclim/resources/ext
<
Windows:
>
$HOME/.eclim/resources/ext
<
vim:ft=eclimhelp
