Vim Script Programming Vim Script (c9s) Fork Me on Github http://github.com/c9s

• Programmable interface • vim script • Perl / Python / Ruby / Mzscheme ...

Outline - Vim Script • Comment • Looping • Variable • Command • Variable scope • Mapping • Special variable • Completion • Function • Autocommand • function scope • Autogroup • built-in function • Utility • Condition • vim-makeﬁle

Prepare

Region Eval http://gist.github.com/444528 * Press ‘V’ then select region * Press ‘e’ to evaluate region

To run script :source [filename] :source % # current file

Debugging :messages :set verbose=10 “ verbose mode :verbose *command*

Help section :help *section* option :help ‘option_name’ mode :help [icv]_..... command :help :command_name

Alias • source => so :so • function => func :func Foo(bar) • endfunction => endf :endf

Variable let variable = 123 let string = “string” let list = [1,2,3] let strlist = [ “bar” , “foo” ] let dict = { ‘phone’: ‘01234567’ } let dict.name = “Chopin” echo dict

Variable Scope • non-preﬁx = global • g: global • s: script • b: buffer • v: vim built-in • a: function arguments

Variable Scope • let var = “string” • let g:var_global = “global” • let s:var_script = “script” • let b:var_buffer = “buffer”

Condition if boo > 2 elseif str == “string” elseif str =~ ‘[a-z]+’ endif

Looping while running == 1 echo “Run...” endwhile for i in [1,2,3,4] endfor

Looping for i in range(1,10) “ i = 1 ~ 10 endfor

Override Function Uppercase fun! Test() .. blah endf

Override Function Uppercase fun! Test() .. blah endf call Test() “ no return value

Override Function Uppercase fun! Test() .. blah return 3 endf let ret = Test() Return 3

Function arguments fun! Foo(bar) echo a:bar endf fun! Foo(...) echo a:000 echo a:001 endf

Function arguments fun! Foo(bar) echo a:bar endf non-modiﬁable fun! Foo(...) echo a:000 echo a:001 endf

Function arguments fun! Foo(bar) echo a:bar endf non-modiﬁable fun! Foo(...) echo a:000 count of args echo a:001 endf

Function arguments fun! Foo(bar) echo a:bar endf non-modiﬁable fun! Foo(...) echo a:000 count of args echo a:001 endf arg1

Function Scope fun! s:Foo() endf Script Scope fun! g:Foo() endf Global Scope fun! b:Foo() endf Buffer Scope

Built-in Functions • List related: add() , remove() , ﬁlter() , map (), len() , sort(), empty(), join(), range() ... • Dictionary related: keys() , values() , has_key() , has_value(), extend() ... • String related: stridx(), strridx(), strlen(), substitute() , submatch(), strpart(), expand () ...

Built-in Functions • List related: add() , remove() , ﬁlter() , map (), len() , sort(), empty(), join(), range() ... • Dictionary related: keys() , values() , has_key() , has_value(), extend() ... • String related: stridx(), strridx(), strlen(), substitute() , submatch(), strpart(), expand () ... *function-list*

Built-in Function • Buffer related: bufnr() , bufexists() , buﬂisted () , bufname() ... etc • Window related: winbufnr(), bufwinnr(), winnr() • Misc: getreg(), setreg(), system(), eventhandler () , getpid() ...

Autoload function Deﬁne your library function: ~/.vim/autoload/foo.vim fun! foo#blah() endf In your script: call foo#blah()

Command com! -range DoWrite :write ﬂags command name execute

Command Deﬁne line range for command: -range -range=% -range=N -count=N

Command Other options: -bang -bar -register -buffer -complete=[type]

Command Template arguments: <line1>,<line2> <count> <bang> <reg> <args> <f-args> <q-args> <lt>

Syntax • syn list • syn keyword [ID] .... • syn match [ID] .... • syn region [ID] ... • hi [ID] [Attributes]

Utilities • vim-makeﬁle • vim-uploader • Vimana

Vim Makeﬁle • make install • make uninstall • make link • make dist
