You can also configure a different pair of keys to + scroll forwards and backwards through completion results. + +- Optional improved 'longest' completion support (after typing some characters, + hitting will highlight the next longest match). +- Built in 'context' completion option which chooses the appropriate completion + type based on the text preceding the cursor. + + - You can also plug in your own functions to determine which completion type + to use. + +- Support for simple completion chaining (falling back to a different + completion type, keyword completion for example, if omni or user completion + returns no results). + +Installation +------------ + +You have a few options when it comes to installing supertab: + +1. Use your linux package manager: + + Some linux distributions include a supertab package so you don't have to + manage the install/upgrade of supertab separately from other software on your + system. + +2. Use a vim plugin manager: + + There are several plugin managers for vim, which will either allow you to + manually clone vim plugin repositories, or will do so for you. Probably the + two most popular ones currently are `pathogen + `_ and `vundle + `_. Please refer to their docs for + instructions on how to install plugins. + +3. And lastly you can use the vimball (.vmb) file found on + `vim.org `_: + + Vimball files are installed by simply opening them in vim and then sourcing + the file: + + :: + + $ vim supertab.vmb + :source % + +Frequently Asked Questions +-------------------------- + +- **Why isn't supertab honoring my configured settings (attempts to complete at the + start of a line, always performs keyword completion instead of my configured + default, etc.)?** + + Chances are that you have a very old version of `snipmate + `_ installed, or something similar, + which will issue a `` when no snippet is found. Supertab use to map to + ``, so this behavior would act as a fallback to supertab, but current + versions of supertab no longer do so, resulting in snipmate bypassing supertab + entirely. + + You can check if this is the case by running the following in vim to see what + is mapped to ``: + + :: + + :verbose imap + + To resolve the issue you can either: + + #. Install my `fork `_ or + #. Upgrade to a more recent snipmate fork, like `garbas/vim-snipmate + `_ + + See `#74 `_ for additional + details. + +- **Why does navigate the completion menu from bottom to top?** + + First, if after reading the explanation below (or if you don't want to bother + reading it), you still want the default to scroll down the list then you can + use: + + :: + + let g:SuperTabDefaultCompletionType = "" + + or if your default completion type is currently `context` then you can use + this instead: + + :: + + let g:SuperTabContextDefaultCompletionType = "" + + Now on to the reasoning behind this. When using `` or `` to start + insert completion, both populate the completion popup with the same list of + words in the same order, the only difference is that `` highlights the + nearest matching word located above the current cursor position, which is the + result at the bottom of the completion popup. Without supertab installed, + continuing to hit `` will walk up the list to next nearest word above the + cursor. + + I think Bram chose to display the results like this so that + + #. the completion logic is the same for `` and ``, only the first + entry to highlight differs + #. so that the behavior of `` mode is consistent, always moving up the + list and + #. when starting `` mode you don't have to switch over to + using `` to get the next nearest entry, just continue to hit ``. + + So, with supertab I wanted to preserve the same behavior. If `` is your + default completion method (supertab defaults to this being the case), then + `` will start it and additional uses of `` will move up the list + instead of down so that you don't have to suddenly switch to using `` + to get the next nearest result. + + Why is `` the supertab default? The original supertab author found (and I + agree with his finding) that while coding, the keyword match you want is + typically the closer of the matches above the cursor, which `` naturally + provides. diff --git a/sources_forked/supertab/doc/supertab.txt b/sources_forked/supertab/doc/supertab.txt new file mode 100755 index 00000000..941a9a05 --- /dev/null +++ b/sources_forked/supertab/doc/supertab.txt @@ -0,0 +1,473 @@ +*supertab.txt* + +Author: Eric Van Dewoestine + Original concept and versions up to 0.32 written by + Gergely Kontra + +This plugin is licensed under the terms of the BSD License.

Introduction *supertab-intro* + +Supertab is a plugin which allows you to perform all your insert completion +(|ins-completion|) using the tab key. + +Supertab requires Vim version 7.0 or above. + +============================================================================== +2. Supertab usage *supertab-usage* + +Using Supertab is as easy as hitting or (shift+tab) while in +insert mode, with at least one non whitespace character before the cursor, to +start the completion and then or again to cycle forwards or +backwards through the available completions. + +Example ('|' denotes the cursor location): + +bar +baz +b| Hitting here will start the completion, allowing you to + then cycle through the suggested words ('bar' and 'baz'). + +============================================================================== +3. Supertab Options *supertab-options* + +Supertab is configured via several global variables that you can set in your +|vimrc| file according to your needs. Below is a comprehensive list of +the variables available. + + +Default Completion Type *supertab-defaultcompletion* + *g:SuperTabDefaultCompletionType* + +g:SuperTabDefaultCompletionType (default value: "") + +Used to set the default completion type. There is no need to escape this +value as that will be done for you when the type is set. + + Example: setting the default completion to 'user' completion: + +> + let g:SuperTabDefaultCompletionType = "" +< + +Note: a special value of 'context' is supported which will result in +super tab attempting to use the text preceding the cursor to decide which +type of completion to attempt. Currently supertab can recognize method calls +or attribute references via '.', '::' or '->', and file path references +containing '/'. If the language you are using doesn't use any of the member +reference characters listed above, or you'd like to add additional patterns, +you can write a custom context function also described in the next section +(Completion context). + + Example: setting the default completion to supertab's 'context' completion: +> + let g:SuperTabDefaultCompletionType = "context" +< + + /usr/l # will use filename completion + myvar.t # will use user completion if completefunc set, + # or omni completion if omnifunc set. + myvar-> # same as above + +When using context completion, super tab will fall back to a secondary default +completion type set by |g:SuperTabContextDefaultCompletionType|. + +Note: once the buffer has been initialized, changing the value of this setting +will not change the default complete type used. If you want to change the +default completion type for the current buffer after it has been set, perhaps +in an ftplugin, you'll need to call *SuperTabSetDefaultCompletionType* like so, +supplying the completion type you wish to switch to: + +> + call SuperTabSetDefaultCompletionType("") +< + + +Secondary default completion type *supertab-contextdefault* + *g:SuperTabContextDefaultCompletionType* + +g:SuperTabContextDefaultCompletionType (default value: "") + +Sets the default completion type used when g:SuperTabDefaultCompletionType is +set to 'context' and no completion type is returned by any of the configured +contexts. + + Note: supertab also supports the b:SuperTabContextDefaultCompletionType + variable allowing you to set the default type separately for the current + buffer, like from an ftplugin for example. + + +Completion contexts *supertab-completioncontexts* + *g:SuperTabCompletionContexts* + +g:SuperTabCompletionContexts (default value: ['s:ContextText']) + +Sets the list of contexts used for context completion. This value should +be a list of function names which provide the context implementation. + +When supertab starts context completion, each of these contexts will be +consulted, in the order they were supplied, to determine the completion type +to use. If a context returns a completion type, that type will be used, +otherwise the next context in the list will be consulted. If after executing +all the context functions, no completion type has been determined, then the +value of |g:SuperTabContextDefaultCompletionType| will be used. + + Note: supertab also supports the b:SuperTabCompletionContexts variable + allowing you to set the list of contexts separately for the current buffer, + like from an ftplugin for example. + +Built in completion contexts: + + s:ContextText *supertab-contexttext* + + The text context will examine the text near the cursor to decide which type + of completion to attempt. Currently the text context can recognize method + calls or attribute references via '.', '::' or '->', and file path + references containing '/'. + + /usr/l # will use filename completion + myvar.t # will use user completion if completefunc set, or + # omni completion if omnifunc set. + myvar-> # same as above + + Supported configuration attributes: + + *g:SuperTabContextTextFileTypeExclusions* + List of file types for which the text context will be skipped. + + *g:SuperTabContextTextOmniPrecedence* (default: ['&completefunc', '&omnifunc']) + *b:SuperTabContextTextOmniPrecedence* + List of omni completion option names in the order of precedence that they + should be used if available. By default, user completion will be given + precedence over omni completion, but you can use this variable to give + omni completion higher precedence by placing it first in the list. + + *g:SuperTabContextTextMemberPatterns* (default: ['\.', '>\?::', '->']) + *b:SuperTabContextTextMemberPatterns* + List of patterns used to determine when omni/user completion should be + used. The default list consists of the most common patterns used to access + module/class/object members. + + Note: For html and xml based files, the buffer local version of the above + two settings are set to trigger omni completion first when encountering a + potential end tag pattern of ' + let g:SuperTabCompletionContexts = ['s:ContextText', 's:ContextDiscover'] + let g:SuperTabContextTextOmniPrecedence = ['&omnifunc', '&completefunc'] + let g:SuperTabContextDiscoverDiscovery = + \ ["&completefunc:", "&omnifunc:"] +< + + In addition to the default completion contexts, you can plug in your own + implementation by creating a globally accessible function that returns + the completion type to use (eg. "\\"). + +> + function MyTagContext() + if filereadable(expand('%:p:h') . '/tags') + return "\\" + endif + " no return will result in the evaluation of the next + " configured context + endfunction + let g:SuperTabCompletionContexts = + \ ['MyTagContext', 's:ContextText', 's:ContextDiscover'] +< + + Here is another example that could be used to add context support for + clojure, and perhaps other lisp variants: + +> + let b:SuperTabCompletionContexts = + \ ['ClojureContext'] + g:SuperTabCompletionContexts + + function! ClojureContext() + let curline = getline('.') + let cnum = col('.') + let synname = synIDattr(synID(line('.'), cnum - 1, 1), 'name') + if curline =~ '(\S\+\%' . cnum . 'c' && synname !~ '\(String\|Comment\)' + return "\\" + endif + endfunction +< + + +Completion Duration *supertab-duration* + *g:SuperTabRetainCompletionDuration* + +g:SuperTabRetainCompletionDuration (default value: 'insert') + +Determines if, and for how long, the current completion type is retained. +The possible values include: +'completion' - The current completion type is only retained for the + current completion. Once you have chosen a completion + result or exited the completion mode, the default + completion type is restored. +'insert' - The current completion type is saved until you exit insert + mode (via ESC). Once you exit insert mode the default + completion type is restored. (supertab default) +'session' - The current completion type is saved for the duration of + your vim session or until you enter a different completion + mode. + + +Preventing completion after... *supertab-preventcomplete* + *g:SuperTabNoCompleteBefore* + *g:SuperTabNoCompleteAfter* + +g:SuperTabNoCompleteBefore (default value: []) +g:SuperTabNoCompleteAfter (default value: ['^', '\s']) + +These two variables are used to control when supertab will attempt completion +or instead fall back to inserting a literal . There are two possible ways +to define these variables: + + 1) by specifying a list of patterns which are tested against the text before + and after the current cursor position that when matched, prevent completion. + So if you don't want supertab to start completion at the start of a line, + after a comma, or after a space, you can set g:SuperTabNoCompleteAfter + to ['^', ',', '\s']. + + 2) by specifying a funcref to a global accessible function which expects + as parameter the text to be inspected (before or after) and, based on that (or + other factors), it returns 1 if completion must be prevented, 0 otherwise. + +Note: That a buffer local version of these variables +(b:SuperTabNoCompleteBefore, b:SuperTabNoCompleteAfter) are also supported +should you wish to have different values depending on the file type for +instance. + +Changing the default mapping *supertab-forwardbackward* + *g:SuperTabMappingForward* + *g:SuperTabMappingBackward* + +g:SuperTabMappingForward (default value: '') +g:SuperTabMappingBackward (default value: '') + +These two variables allow you to set the keys used to kick off the current +completion. By default this is and . To change to something +like and , you can add the following to your |vimrc|. + +> + let g:SuperTabMappingForward = '' + let g:SuperTabMappingBackward = '' +> + +Note: if the above does not have the desired effect (which may happen in +console version of vim), you can try the following mappings. Although the +backwards mapping still doesn't seem to work in the console for me, your +milage may vary. + +> + let g:SuperTabMappingForward = '' + let g:SuperTabMappingBackward = '' +< + + +Inserting true tabs *supertab-mappingtabliteral* + *g:SuperTabMappingTabLiteral* + +g:SuperTabMappingTabLiteral (default value: '') + +Sets the key mapping used to insert a literal tab where supertab would +otherwise attempt to kick off insert completion. The default is '' +(ctrl-tab) which unfortunately might not work at the console. So if you are +using a console vim and want this functionality, you may have to change it to +something that is supported. Alternatively, you can escape the with + (see |i_CTRL-V| for more infos). + +See also |supertab-preventcomplete|. + + +Enhanced longest match support *supertab-longestenhanced* + *g:SuperTabLongestEnhanced* + +g:SuperTabLongestEnhanced (default value: 0) + +When enabled and 'longest' is in your |completeopt| setting, supertab will +provide an enhanced longest match support where typing one or more letters and +hitting tab again while in a completion mode will complete the longest common +match using the new text in the buffer. + +For example, say you have a buffer with the following contents: + FooBarFoo + FooBar + Foo + FooBarBaz +And you then type F. Vim's builtin longest support will complete the +longest common text 'Foo' and offer 'FooBarFoo', 'FooBar', 'Foo', and +'FooBarBaz' as possible completions. With supertab's longest match +enhancement disabled, typing B while still in the completion mode will +end up completing 'FooBarBaz' or 'FooBarFoo' depending your settings, instead +of the next longest common match of 'FooBar'. With supertab's enhanced +longest match feature enabled, the typing of B will result in the next +longest text being completed. + + +Preselecting the first entry *supertab-longesthighlight* + *g:SuperTabLongestHighlight* + +g:SuperTabLongestHighlight (default value: 0) + +Sets whether or not to pre-highlight the first match when completeopt has the +popup menu enabled and the 'longest' option as well. When enabled, will +kick off completion and pre-select the first entry in the popup menu, allowing +you to simply hit to use it. + + +Mapping to end completion *supertab-crmapping* + *g:SuperTabCrMapping* + +g:SuperTabCrMapping (default value: 0) + +When enabled, will cancel completion mode preserving the current text. + +Compatibility with other plugins: + - endwise: compatible + - delimitMate: not compatible (disabled if the delimitMate mapping is + detected.) + +Note: if you have an insert expression mapping with a in it or an insert +abbreviation containing a , then supertab will not create a mapping +which could potentially cause problems with those. + + +Auto close the preview window *supertab-closepreviewonpopupclose* + *g:SuperTabClosePreviewOnPopupClose* + +g:SuperTabClosePreviewOnPopupClose (default value: 0) + +When enabled, supertab will attempt to close vim's completion preview window +when the completion popup closes (completion is finished or canceled). + + +Completion ignore/match case *supertab-completecase* + *g:SuperTabCompleteCase* + +g:SuperTabCompleteCase (default value: 'inherit') + +When issuing completions (keyword and potentially others), the value of your +|'ignorecase'| setting will determine what results are returned based on +whether or not you've chosen to ignore case or not. However, you may have +|'ignorecase'| set or unset for other reasons and don't want that value +considered when using insert completion. SuperTab allows you temporarily +override |'ignorecase'| by setting g:SuperTabCompleteCase to either 'ignore' +or 'match' depending on whether you want to always ignore or match case when +using insert completion. + +Note: third party omni/user completion plugins may or may not honor +|'ignorecase'|. If they do not, then you can probably contact them to add that +support. + +Completion Chaining *supertab-completionchaining* + +SuperTab provides the ability to chain one of the completion functions +(|completefunc| or |omnifunc|) together with one of the default vim +completion key sequences (|ins-completion|), giving you the ability to attempt +completion with the first, and upon no results, fall back to the second. + +To utilize this feature you need to call the *SuperTabChain* function where +the first argument is the name of a vim compatible |complete-function| and the +second is one of vim's insert completion (|ins-completion|) key bindings +(, , , etc). Calling this function will set the current +buffer's |completefunc| option to a supertab provided implementation which +utilizes the supplied arguments to perform the completion. + +Here is an example that can be added to your .vimrc which will setup the +supertab chaining for any filetype that has a provided |omnifunc| to first +try that, then fall back to supertab's default, , completion: + +> + autocmd FileType * + \ if &omnifunc != '' | + \ call SuperTabChain(&omnifunc, "") | + \ endif +< + +You can also specify whether or not the 'context' completion method will +be used as part of your completion chaining. If you've already set your +default completion type to 'context', then no further action is needed. If +however you haven't set that or don't want to use 'context' completion in this +case, then you can supply a third argument to SuperTabChain which is a boolean +(1 or 0) indicationg whether you want to use 'context' completion (1) or not +(0). + +Here is an example where 'context' is the global default and completion +chaining is enabled for file types that have omni completion support: + +> + let g:SuperTabDefaultCompletionType = 'context' + autocmd FileType * + \ if &omnifunc != '' | + \ call SuperTabChain(&omnifunc, "") | + \ endif +< + +This configuration will result in a completion flow like so: + + if text before the cursor looks like a file path: + use file completion + elif text before the cursor looks like an attempt to access a member + (method, field, etc): + use user completion + where user completion is currently set to supertab's + completion chaining, resulting in: + if omni completion has results: + use omni completion + else: + use keyword completion + else: + use keyword completion + +Note: Completion chaining only supports chaining 1 completion function (omni +or user) with 1 regular completion keybinding. All other combinations of +completions (2 or more completion functions, 2 or more key bindings, etc.) are +not supported due to limitations imposed by vim's code completion +implementation. + +Note: If the |completefunc| or |omnifunc| use vim's |complete_add()| instead +of returning completion results as a list, then Supertab's completion chaining +won't work properly with it since Supertab uses the function result to +determine if it should fallback to the next completion type. + +vim:tw=78:ts=8:ft=help:norl: diff --git a/sources_forked/supertab/ftplugin/html.vim b/sources_forked/supertab/ftplugin/html.vim new file mode 100755 index 00000000..4bd2385d --- /dev/null +++ b/sources_forked/supertab/ftplugin/html.vim @@ -0,0 +1,61 @@ +" Author: Eric Van Dewoestine +" +" License: {{{ +" Copyright (c) 2014 +" All rights reserved. +" +" Redistribution and use of this software in source and binary forms, with +" or without modification, are permitted provided that the following +" conditions are met: +" +" * Redistributions of source code must retain the above +" copyright notice, this list of conditions and the +" following disclaimer. +" +" * Redistributions in binary form must reproduce the above +" copyright notice, this list of conditions and the +" following disclaimer in the documentation and/or other +" materials provided with the distribution. +" +" * Neither the name of Gergely Kontra or Eric Van Dewoestine nor the names +" of its contributors may be used to endorse or promote products derived +" from this software without specific prior written permission of Gergely +" Kontra or Eric Van Dewoestine. +" +" THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS +" IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, +" THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +" PURPOSE ARE DISCLAIMED.
