## Introduction



µTemplate is a template-files loader for Vim. Once loaded, templates are interpreted and expanded according to a flexible syntax.

## Features

  * Template-files can be expanded:

    * automatically when opening a new buffer (unless deactivated from the .vimrc),

    * explicitly through menus or the command line,

    * from the INSERT-mode in a snippet-like fashion ;

    * from the VISUAL-mode to surround the selection with a snippet ;

  * All snippets are defined in their own template-file ;

  * The template-files can be overridden by the user, or in the context of a specific project ;

  * Filetype specific snippets can be defined for the INSERT-mode (they can be inherited, e.g. C snippets can be used from C++, Java, _etc._), the list of matching snippets will be presented with a hint for each snippet ;

  * Computed VimL expressions can be inserted ;

  * VimL instructions can be executed during the expansion ;

  * Template-files can include other template-files in a function-like manner (parameters are even supported);

  * Fully integrated with my [placeholders-system](http://github.com/LucHermitte/lh-brackets) ;

  * Supports re-indentation (if desired), and Python indentation ;

  * Works well with vim folding ;

  * I18n friendly ;

  * The expansion happens after any [_local vimrcs_](http://github.com/LucHermitte/local_vimrc) present are loaded -- in order to set project-specific variables before the expansion is done.



  * Thanks to [Tom Link's StakeHolders](http://www.vim.org/scripts/script.php?script_id=3326) plugin, µTemplate does now have tied placeholders (modifying one named placeholder modifies other placeholders with the same name). Not installing Stakeholders will not prevent you from using µTemplate.



However, it misses the following features:

  * Several snippets per template-file -- It's extremely unlikely that µTemplate will ever work this way.

  * One key that does everything: expansion of snippets/previously typed keywords/dictionary/..., or jump to the next placeholder depending on the context.



## Examples



A few examples are better than a long speech, check the [documentation](doc/mu-template.txt) for more precisions.



Note: all the default template-files shipped with mu-template can be browsed from the [repository](after/template/)



### C-`if` snippet

Snippet that uses `¡`, `s:Surround()`, [lh-style's styling feature](http://github.com/LucHermitte/lh-style#formatting.of.brackets.characters)

```

VimL:"{if} Template-File, Luc Hermitte

VimL:" hint: if (cond) { action }

VimL: let s:value_start = '¡'

VimL: let s:value_end = '¡'

VimL: let s:reindent = 1

VimL: let s:marker_open = '<+'

VimL: let s:marker_close = '+>'

if(¡substitute(s:Surround(2, '<+cond+>'), '^\_s*\|\_s*$', '', 'g')¡){

¡s:Surround(1, '<+code+>')¡

}<+s:TerminalPlaceHolder()+>

```



### C-`case` snippet

Snippet that uses `¡`, `s:TerminalPlaceHolder()`, [lh-style's styling feature](http://github.com/LucHermitte/lh-style#formatting.of.brackets.characters), and that takes options.

```

VimL:" {case:} File Template, Luc Hermitte, 05th Jan 2011

VimL:" hint: case {tag: ...; break;}

VimL: let s:value_start = '¡'

VimL: let s:value_start = '¡'

VimL: let s:value_end = s:value_start

VimL: let s:marker_open = '<+'

VimL: let s:marker_close = '+>'

VimL: let s:case = empty(s:Args()) ? lh#marker#txt('case') : (s:Args()[0])

VimL: let s:_with_block2 = len(s:Args()) <= 1 ? INPUT("Insert a block for the case (0/1) ?") : (s:Args()[1])

case <+s:case+>:

<+s:_with_block2?'{':''+>

<+¡substitute(s:case, lh#marker#txt('\(.\{-}\)'), '\1', '')¡-code+>;

break;

<+s:_with_block2?'}':''+>

```



### Vim-`plugmap` snippet

Recursive snippet that takes options, uses `s:Include()`,

`s:SurroundableParam()`, `:MuT`-commands, and that contain a loop



```

VimL:" ``VimL  mappings'' File Template, Luc Hermitte 

VimL:" hint: mapping + default mapping

VimL: let s:reindent     = 1

VimL: let s:marker_open  = '<+'

VimL: let s:marker_close = '+>'

MuT:  let s:mapmode = s:SurroundableParam('mode', 1, lh#option#unset())

MuT:  let s:plugname = s:SurroundableParam('plug', 2, lh#option#unset())

MuT:  if lh#option#is_unset(s:mapmode)

MuT:    let s:mapmode = INPUT('Mode (invox)?', lh#marker#txt('mode'))

MuT:  endif

MuT:  if lh#option#is_unset(s:plugname)

MuT:    let s:plugname =  INPUT('?',       lh#marker#txt('name'))

MuT:  endif

VimL: call s:Include('get-script-kind', 'vim/internals')

VimL: let s:buffer = s:ftplug ? ' ' : ''

MuT:  if strlen(s:mapmode) == 1 || lh#marker#is_a_marker(s:mapmode)

<+s:mapmode+>noremap <+s:buffer+> <+s:plugname+> <+definition+>

if !hasmapto('<+s:plugname+>', '<+s:mapmode+>')

  <+s:mapmode+>map <+s:buffer+>  <+keybinding+> <+s:plugname+>

endif

MuT:  else

VimL:    for mode in split(s:mapmode, '\zs') | call s:Include('plugmap', 'vim', {'mode': mode, 'plug': s:plugname}) | endfor

MuT:  endif

```



### Interactive template-file: C++ Class Template

```

VimL:" C++ Class Template, Luc Hermitte

VimL:" hint: Class Wizard (asks for class semantics)

VimL: let s:value_start = '¡'

VimL: let s:value_end = '¡'

VimL: let s:reindent = 1

VimL: let s:marker_open = '<+'

VimL: let s:marker_close = '+>'

VimL: let s:clsname = empty(s:Args()) ? INPUT("class name ?", lh#marker#txt(expand('%:t:r'))) : (s:Args()[0])

VimL: call CppDox_ClassWizard(s:clsname)

VimL:"

VimL:"

VimL: call s:Include("section-sep", "c", s:clsname." class")

VimL: silent! unlet s:doc

VimL: let s:doc = []

VimL: let s:doc += [{ "tag": "ingroup", "text": "g".lh#option#get('dox_group', lh#marker#txt('Group')) }]

VimL: let s:doc += [{ "tag": "brief" }]

VimL: let s:doc += [{ "text": "\n" }]

VimL: let s:doc += [{ "text": "<+doc+>" }]

VimL: let s:doc += [{ "text": "\n" }]

VimL: let s:doc += [{ "tag": "invariant"}]

VimL: let s:doc += [{ "text": "\n" }]

VimL: let s:doc += [{ "tag": "semantics"}]

VimL: let s:doc += [{ "text": g:CppDox_semantics}]

VimL: let s:doc += [{ "text": "\n" }]

VimL: let s:doc += [{ "tag": "version", "text": "$"."revision$"}]

VimL: let s:doc += [{ "tag": "author"}]

VimL: call s:Include("formatted-comment", "cpp/internals", s:doc)

class <+s:clsname+>

¡g:CppDox_inherits¡

{

public:

/**<+lh#dox#tag('name')+> Construction/destruction

*/

//<+lh#dox#tag('{')+>

VimL: let s:fn_comments = { }

VimL: let s:fn_comments.brief = "Default constructor."

VimL: let s:fn_comments.throw = {"optional": 1}

VimL: call s:Include("function-comment", "cpp/internals",s:fn_comments)

<+s:clsname+>();



VimL: "

VimL: " not documented, this is :DOX job

VimL: "

VimL: " todo: support using default implementations

MuT: if g:CppDox_do_copy

VimL: call s:Include("copy-constructor", "cpp", s:clsname)

VimL: call s:Inject([""])

VimL: call s:Include("copy-and-swap", "cpp", s:clsname)



MuT: endif

VimL: call s:Include("destructor", "cpp",{"name":(s:clsname), "virtual": (g:CppDox_isVirtualDest) })

//<+lh#dox#tag('}')+>



<+Other public functions+>;



¡IF(strlen(g:CppDox_protected_members), "protected:\n", '')¡

¡g:CppDox_protected_members¡

private:

```



### Completely useless recursive example

  * test.template

```

VimL: let s:value_start  = '¡'

VimL: let s:value_end    = '¡'

VimL: let s:marker_open  = '<+'

VimL: let s:marker_close = '+>'

VimL: let s:var = 1

BEGIN<++>

/*

 * ¡'$'¡Id$

 */

¡s:var¡

a¡s:var¡

¡s:var + 5¡a

a¡s:var¡a¡s:var¡

a¡s:var¡a¡s:var¡a

here <+we go+>

VimL: let s:msg =''

VimL: call s:Include('test-included')

VimL: let s:msg =' again'

VimL: call s:Include('test-included')



------

Some tests:

VimL: let s:expr = "first line\nsecond line\n "

text ¡s:expr¡

text

END

```

  * test-included.template

```

VimL: let s:times = exists('s:times') ? (s:times+1) : 1

This part has been included¡s:msg¡ ¡((s:times==1)?'once':(s:times==2 ? 'twice' : (s:times.' times')))¡.

VimL: if s:times <= 4 | call s:Include('test-included') | endif

VimL: silent! unlet s:times

```



## Installation

  * Requirements: Vim 7.+, [lh-vim-lib](http://github.com/LucHermitte/lh-vim-lib), [lh-style](http://github.com/LucHermitte/lh-style), and my [bracketing-system](http://github.com/LucHermitte/lh-brackets), and optionally [lh-dev](http://github.com/LucHermitte/lh-dev).

  * With [vim-addon-manager](https://github.com/MarcWeber/vim-addon-manager), install `mu-template@lh`. This is the preferred method because of the various dependencies.



    ```vim

    ActivateAddons mu-template@lh

    " And don't forget

    ActivateAddons stakeholders

    " don't forget also to support a few default snippets

    ActivateAddons lh-dev

    ```



  * or you can use [vim-flavor](https://github.com/kana/vim-flavor) that also

    supports dependencies



    ```

    flavor 'LucHermitte/mu-template'

    " And don't forget

    flavor 'tomtom/stakeholders_vim'

    " don't forget also to support a few default snippets

    flavor 'LucHermitte/lh-dev'

    ```



  * N.B.: installing [lh-cpp](http://github.com/LucHermitte/lh-cpp) or [lh-refactor](http://github.com/LucHermitte/lh-refactor) with VAM or vim-flavor will also install µTemplate.

  * or you can clone the git repositories

    ```bash

    git clone [email protected]:LucHermitte/lh-vim-lib.git

    git clone [email protected]:LucHermitte/lh-style.git

    git clone [email protected]:LucHermitte/lh-brackets.git

    git clone [email protected]:LucHermitte/mu-template.git

    # and don't forget:

    git clone [email protected]:tomtom/stakeholders_vim.git

    # don't forget also to support a few default snippets

    git clone [email protected]:LucHermitte/lh-dev.git

    ```



  * or with Vundle/NeoBundle:

    ```vim

    Bundle 'LucHermitte/lh-vim-lib'

    Bundle 'LucHermitte/lh-style'

    Bundle 'LucHermitte/lh-brackets'

    Bundle 'LucHermitte/mu-template'

    " and don't forget:

    Bundle 'tomtom/stakeholders_vim'

    " don't forget also to support a few default snippets

    Bundle 'LucHermitte/lh-dev'

    ```



### Note: regarding [COC](https://github.com/neoclide/coc.nvim)



Since v.4.4.0, µTemplate delegates the selection of its snippets to COC, when

COC is detected.
