VimClojure - A Clojure Environment
==================================
Introduction
------------
VimClojure is a filetype plugin and development environment for Clojure. It
provides indenting, syntax highlighting and – if configured – interactive
features like omni completion, documentation lookup and a Repl running in a
Vim buffer.
Nailgun Server *clj-nailgun-server*
--------------
To use the interactive part you have to start the nailgun server via the jar
file. Make sure, that clojure and clojure-contrib are in your classpath and
start the com.martiansoftware.nailgun.NGServer class. Example invocation:
>
java -cp clojure.jar:clojure-contrib.jar:vimclojure.jar com.martiansoftware.nailgun.NGServer 127.0.0.1
<
This may look different depending on your system.
You can stop the server by invoking the nailgun client with the ng-stop
argument.
>
ng ng-stop
<
Set the clj_want_gorilla variable in your vimrc.
>
let g:clj_want_gorilla = 1
<
Note: Should there be an error when executing an interactive command
and the error message goes away to quickly, you can use |:messages| to
recall the message and read it conveniently without time pressure.
Syntax Highlighting *ft-clj-syntax*
-------------------
The clojure syntax highlighting provides several options:
>
g:clj_highlight_builtins
If it exists and is nonzero, then Clojure's builtin functions
are highlighted. This useful to distuingish macros and special
forms from functions.
g:clj_highlight_contrib
If it exists and is nonzero, then Clojure-Contrib's functions
are highlighted. (Currently incomplete)
g:clj_paren_rainbow
If it exists and is nonzero, then differing levels of
parenthesisation will receive different highlighting.
<
The g:clj_paren_rainbow option provides 10 levels of individual colorisation
for the parentheses. Because of the quantity of colorisation levels, unlike
non-rainbow highlighting, the rainbow mode specifies its highlighting using
ctermfg and guifg, thereby bypassing the usual colorscheme control using
standard highlighting groups. The actual highlighting used depends on the
dark/bright setting (see |'bg'|).
Keybindings
-----------
Note: <LocalLeader> is a Vim feature. More information can be found
under the |maplocalleader| help topic.
You can redefine any key mapping using some autocommand in your .vimrc file.
All mappings use so-called Plugs. Simply prepend <Plug>Clojure to the given
Plug name and your setting will override the default mapping.
>
aucmd BufRead,BufNewFile *.clj nmap xyz <Plug>ClojureEvalToplevel
<
<LocalLeader>et *et* *EvalToplevel*
Send off the toplevel sexpression currently
containing the cursor to the Clojure server.
<LocalLeader>ef *ef* *EvalFile*
Send off the current file to the Clojure Server.
<LocalLeader>eb *eb* *EvalBlock*
Send off the the mark visual block to the
Clojure server. Obviously this mapping is only
active in visual mode.
Note: This does not check for structure.
<LocalLeader>el *el* *EvalLine*
Send off the current line to the Clojure Server.
Note: This does not check for structure.
<LocalLeader>ep *ep* *EvalParagraph*
Send off the current paragraph to the Clojure Server.
Note: This does not check for structure.
<LocalLeader>rf *rf* *RequireFile*
Require the namespace of the current file with
the :reload flag. Note: For this to work with
a remote Clojure server, the files have to put in
place before issueing the command, eg. via scp
or NFS.
<LocalLeader>rF *rF* *RequireFileAll*
Require the namespace of the current file with
the :reload-all flag. Note: For this to work with
a remote Clojure server, the files have to put in
place before issueing the command, eg. via scp
or NFS.
<LocalLeader>me *me* *MacroExpand*
Expand the innermost sexpression currently
containing the cursor using macroexpand.
<LocalLeader>m1 *m1* *MacroExpand1*
Same as MacroExpand, but use macroexpand-1.
<LocalLeader>lw *lw* *DocLookupWord*
Lookup up the word under the cursor and print
the documentation for it via (doc).
<LocalLeader>li *li* *DocLookupInteractive*
Lookup the documentation of an arbitrary word.
The user is prompted for input.
<LocalLeader>fd *fd* *FindDoc*
Find a the documentation for a given pattern
with (find-doc). The user is prompted for input.
<LocalLeader>jw *jw* *JavadocLookupWord*
Open the javadoc for the word under the cursor
in an external browser.
<LocalLeader>ji *ji* *JavadocLookupInteractive*
Open the javadoc for an arbitrary word in an
external browser. The user is prompted for input.
<LocalLeader>sw *sw* *SourceLookupWord*
Show a read-only view of the source the word under
the cursor. For this to work, the source must be
available in the Classpath or as a file (depending
on how the source was loaded).
<LocalLeader>si *si* *SourceLookupInteractive*
Show a read-only view of the source of an arbitrary
word. For this to work, the source must be available
in the Classpath or as a file (depending on how the
source was loaded).
<LocalLeader>gw *gw* *GotoSourceWord*
Goto the source of the word under the cursor. For this
to work, the source must be available in a directory
of the |'path'| option. The directories in the
CLOJURE_SOURCE_DIRS environment variable will be added
to the |'path'| setting.
<LocalLeader>gi *gi* *GotoSourceInteractive*
Goto the source of an arbitrary word. For this to work,
the source must be available in a directory of the
|'path'| option. The directories in the
CLOJURE_SOURCE_DIRS environment variable will be added
to the |'path'| setting.
<LocalLeader>mw *mw* *MetaLookupWord*
Lookup the meta data of the word under the cursor.
<LocalLeader>mi *mi* *MetaLookupInteractive*
Lookup the meta data of an arbitrary word. The
user is prompted for input.
<LocalLeader>sr *sr* *StartRepl*
Start a new Vim Repl in a fresh buffer. There
might be multiple Repls at the same time.
Vim Repl
--------
Start a Repl via the |sr| shortcut. At the prompt just type expressions.
Hitting enter will determine, whether the expression is complete and
will send it to the Clojure instance. In case the expression is incomplete,
eg. after "(defn foo" will result in a newline for multiline expressions.
Previously sent expressions may be recalled via <C-Up> and <C-Down>.
Note: sending multiple expressions will save them in the same history
entry. So playing back with <C-Up> will again send all of the contained
expressions.
The Plugs are:
- <Plug>ClojureReplEnterHook for the enter key
- <Plug>ClojureReplUpHistory for going backwards in history (<C-Up>)
- <Plug>ClojureReplDownHistory for going forwards in history (<C-Down>)
The following convenience commands are provided:
- ,close - close the Repl and free the Repl resources in the server process
- ,st - print a stack trace of *e as with clojure.contrib.stacktrace
- ,ct - print a cause trace of *e as with clojure.contrib.stacktrace
Pretty Printing
---------------
In case Tom Faulhaber's cl-format package is available in the Classpath
it will be used for pretty printing, eg. of macroexpansions. The Repl
can be told to use pretty printing via a global Var.
>
(set! de.kotka.vimclojure.repl/*print-pretty* true)
<
Omni Completion
---------------
VimClojure supports omni completion for Clojure code. Hitting <C-X><C-O> in
insert mode will try to provide completions for the item in front of the
cursor.
The completion tries to be somewhat intelligent in what it completes.
- a word starting with an upper case letter will be completed to an
imported class.
Str<C-x><C-o> => String, StringBuilder, ...
- a word containing dots will be completed to a namespace.
c.c<C-x><C-o> => clojure.core, clojure.contrib.repl-utils, ...
- everything else will be completed to a Var, an alias or namespace.
- a word containing a slash will be handled differently
- if the word starts with an upper case letter, will complete
static fields of the given class
String/va<C-x><C-o> => String/valueOf
- otherwise it is treated as a namespace or alias
clojure.core/re<C-x><C-o> => clojure.core/read, ...
The completion uses certain characters to split the matching. This are
hyphens and (for namespaces) dots. So r-s<C-x><C-o> matches read-string.
Note: Completion of symbols and keywords is also provided via the <C-N>
functionality of Vim.
