+snipMate & UltiSnip Snippets
+============================
+
+[![Build Status](https://travis-ci.org/honza/vim-snippets.svg)](https://travis-ci.org/honza/vim-snippets)
+
+This repository contains snippets files for various programming languages.
+
+It is community-maintained and many people have contributed snippet files and
+other improvements already.
+
+Contents
+--------
+
+- `snippets/*`: snippets using snipMate format
+- `UltiSnips/*`: snippets using UltiSnips format
+
+Snippet engines supporting vim-snippets
+----------------------------------------
+
+There are different forks of snippet engines which allow the user to insert
+snippets by typing the name of a snippet hitting the expansion mapping.
+
+- [github.com/SirVer/ultisnips](https://github.com/SirVer/ultisnips):
+ python, supports all snippets in this repo.
+- [github.com/garbas/vim-snipmate](https://github.com/garbas/vim-snipmate):
+ VimL, snipmate-snippets, engine sometimes behaves strange. Supports
+ snippets/*
+- [github.com/Shougo/neosnippet](https://github.com/Shougo/neosnippet.vim):
+ VimL, supports snippets/* with some configuration.
+- [github.com/drmingdrmer/xptemplate](https://github.com/drmingdrmer/xptemplate):
+ Totally different syntax, does not read snippets contained in this file, but
+ it is also very powerful. It does not support vim-snippets (just listing it
+ here for completeness)
+
+There tries to be a more comprehensive list (which still is incomplete) here:
+http://vim-wiki.mawercer.de/wiki/topic/text-snippets-skeletons-templates.html
+
+UltiSnips has additional features such as high speed, nesting snippets,
+expanding snippets in snippets and offers powerful transformations on text in
+snippets (like visual selections or placeholder texts).
+
+Which one to use? If you have python give
+[SirVer/ultisnips](https://github.com/SirVer/ultisnips) a try because its fast
+and has the most features.
+
+If you have VimL only (vim without python support) your best option is using
+[garbas/vim-snipmate](https://github.com/garbas/vim-snipmate) and cope with the
+minor bugs found in the engine.
+
+Q: Should "snipMate be deprecated in favour of UltiSnips"?
+
+A: No, because snipMate is VimL, and UltiSnips requires Python.
+Some people want to use snippets without having to install Vim with Python
+support. Yes - this sucks.
+
+One solution would be: Use snippets if they are good enough, but allow overriding them
+in UltiSnips. This would avoid most duplication while still serving most users.
+AFAIK there is a nested-placeholder branch for snipMate too. snipMate is still
+improved by Adnan Zafar. So maybe time is not ready to make a final decision yet.
+
+[github issue/discussion](https://github.com/honza/vim-snippets/issues/363)
+
+Vendor Snippets
+---------------
+
+Additional library and framework snippets are available for UltiSnips users in
+the `UltiSnips/` directory. These files are removed from the default language
+namespaces to prevent them from all being loaded automatically. If there is a
+separate library, framework, or package you would like to support open a pull
+request!
+
+Additional snippets can be added to the current buffer with the
+`:UltiSnipsAddFiletypes` command followed by the snippet name without the
+"snippets" ending. For example, to add the JavaScript Jasmine snippets, run:
+`:UltiSnipsAddFiletypes javascript-jasmine`. To have this snippet loaded
+everytime a JavaScript file is opened or created you can add the command to your
+ -`.vim/ftplugin/javascript.vim` file. Another way is to add
+ `autocmd FileType js UltiSnipsAddFiletypes javascript-jasmine` in your `.vimrc`.
+
+
+For more see the UltiSnips docs (`:help UltiSnips`).
+
+Installation
+------------
+
+First be aware that there are many options, see "Snippet engines" above.
+Second be aware than there are [tons of plugin managers](http://vim-wiki.mawercer.de/wiki/topic/vim%20plugin%20managment.html)
+which is why Marc Weber thinks that it doesn't make sense to repeat the same
+repetitive information everywhere.
+
+*Recommended way:*
+[vim-addon-manager](https://github.com/MarcWeber/vim-addon-manager) (because Marc Weber wrote it for exactly
+this reason, it supports simple dependency management). E.g. you're done by this
+line in your `.vimrc`:
+
+```vim
+" assuming you want to use snipmate snippet engine
+ActivateAddons vim-snippets snipmate
+```
+
+[vim-pi](https://bitbucket.org/vimcommunity/vim-pi/issue/90/we-really-need-a-web-interface)
+Is the place to discuss plugin managers and repository resources.
+
+About how to install snipMate see [snipmate@garbas](https://github.com/garbas/vim-snipmate)
+
+(Bundle, Pathogen, git clone - keywords to make people find this link by ctrl-f search)
+I know that I should be reading the docs of the snippet engine, just let me copy paste into my `.vimrc`:
+[See this pull request](https://github.com/honza/vim-snippets/pull/307/files).
+
+TROUBLE
+=======
+
+If you still have trouble getting this to work create a GitHub ticket, ask on
+IRC or the mailing list.
+
+Policies / for contributors
+---------------------------
+
+Some snippets are useful for almost all languages, so let's try to have the same
+triggers for them:
+
+```
+if : if without else
+ife: if $1 else $2
+eif : else if ($1) { .. }
+el : else ..
+wh : while (cond) ...
+```
+
+Don't add useless placeholder default texts like:
+
+```
+if (${1:condition}){
+ ${2:some code here}
+}
+```
+instead use:
+
+```
+if (${1}){
+ ${2}
+}
+```
+
+Exception: Functions which are used less often, such as Vim's `matchall()`, `matchstr()`
+functions which case hints may be helpful to remember order. In the VimL case
+get vim-dev plugin which has function completion
+
+Thus for conditions (while, if ..) and block bodies just use ${N} - Thanks
+
+Open questions:
+What about one line if ee then .. else .. vs if \n .. then \n ... \n else \n .. ?
+Which additional policies to add?
+Discuss at: https://github.com/honza/vim-snippets/issues/230
+
+*folding markers*:
+Until further work is done on `vim-snipmate`, please don't add folding markers
+into snippets. `vim-snipmate` has some comments about how to patch all snippets
+on the fly adding those.
+
+Currently all snippets from UltiSnips have been put into UltiSnips - some work
+on merging should be done (dropping duplicates etc). Also see engines section above.
+
+Related repositories
+--------------------
+
+We also encourage people to maintain sets of snippets for particular use cases
+so that all users can benefit from them. People can list their snippet repositories here:
+
+* https://github.com/rbonvall/snipmate-snippets-bib (snippets for BibTeX files)
+* https://github.com/sudar/vim-arduino-snippets (snippets for Arduino files)
+* https://github.com/zedr/zope-snipmate-bundle.git (snippets for Python, TAL and ZCML)
+* https://github.com/bonsaiben/bootstrap-snippets (snippets for Twitter Bootstrap markup, in HTML and Haml)
+* https://github.com/sniphpets (advanced snippets for PHP, Symfony 2/3, Doctrine and etc.)

+Future - ideas - examples
+-------------------------
+
+[overview snippet engines](http://vim-wiki.mawercer.de/wiki/topic/text-snippets-skeletons-templates.html)
+If you have ideas you can add them to that list of "snippet engine features by example".
+
+Historical notes
+----------------
+
+[vim-snipmate][1] was originally started by [Michael Sanders][2] who has now
+unfortunately abandoned the project. [Rok Garbas][3] is now maintaining a
+[fork][4] of the project in hopes of improving the existing code base.
+
+Versions / dialects / ..
+========================
+
+There are some issues, such as newer language versions may require other
+snippets than older. If this exists we currently recommend doing this:
+
+* add snippets/ruby.snippets (common snippets)
+* add snippets/ruby-1.8.snippets (1.8 only)
+* add snippets/ruby-1.9.snippets (1.9 only)
+
+then configure https://github.com/garbas/vim-snipmate this way:
+
+```vim
+let g:snipMate = {}
+let g:snipMate.scope_aliases = {}
+let g:snipMate.scope_aliases['ruby'] = 'ruby,ruby-rails,ruby-1.9'
+```
+
+If it happens that you work on a project requiring ruby-1.8 snippets instead,
+consider using `vim-addon-local-vimrc` and override the filetypes.
+
+Well - of course it may not make sense to create a new file for each
+ruby-library-version triplet. Sometimes postfixing a name such as
+
+```
+migrate_lib_20_down
+migrate_lib_20_up
+```
+
+will do it then if syntax has changed.
+
+Language maintainers
+--------------------
+
+No one can really be proficient in all programming languages. If you would like
+to maintain snippets for a language, please get in touch.
+
+Notes: People are interested in snippets - and their interest may wane again.
+This list is kept up-to-date on a best effort basis.
