82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	23
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	24 You can write a Vim script in such a way that many people can use it. This is
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	25 called a plugin. Vim users can drop your script in their plugin directory and
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	26 use its features right away \|add-plugin\|.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	27
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	28 There are actually two types of plugins:
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	29
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	30 global plugins: For all types of files.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	31 filetype plugins: Only for files of a specific type.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	32
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	33 In this section the first type is explained. Most items are also relevant for
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	34 writing filetype plugins. The specifics for filetype plugins are in the next

29066 f8e9d5023bf6 Update runtime files Bram Moolenaar <Bram@vim.org> parents: 28933 diff changeset	37 We will use \|Vim9\| syntax here, the recommended way to write new plugins.
f8e9d5023bf6 Update runtime files Bram Moolenaar <Bram@vim.org> parents: 28933 diff changeset	38 Make sure the file starts with the `vim9script` command.

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	41 NAME
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	42
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	43 First of all you must choose a name for your plugin. The features provided
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	44 by the plugin should be clear from its name. And it should be unlikely that
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	45 someone else writes a plugin with the same name but which does something
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	46 different.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	47
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	48 A script that corrects typing mistakes could be called "typecorrect.vim". We
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	49 will use it here as an example.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	50
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	51 For the plugin to work for everybody, it should follow a few guidelines. This
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	52 will be explained step-by-step. The complete example plugin is at the end.

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	75 You need to use `vimscript` as the very first command. Best is to put it in

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	78 The script we are writing will have a `finish` command to bail out when it is
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	79 loaded a second time. To avoid that the items defined in the script are lost
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	80 the "noclear" argument is used. More info about this at \|vim9-reload\|.

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	85 You will probably add new corrections to the plugin and soon have several
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	86 versions lying around. And when distributing this file, people will want to
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	87 know who wrote this wonderful plugin and where they can send remarks.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	88 Therefore, put a header at the top of your plugin: >

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	94 About copyright and licensing: Since plugins are very useful and it's hardly
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	95 worth restricting their distribution, please consider making your plugin

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	104 It is possible that a user doesn't always want to load this plugin. Or the
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	105 system administrator has dropped it in the system-wide plugin directory, but a
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	106 user has his own plugin he wants to use. Then the user must have a chance to
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	107 disable loading this specific plugin. These lines will make it possible: >
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	108
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	109 7 if exists("g:loaded_typecorrect")
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	110 8 finish
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	111 9 endif

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	114 This also avoids that when the script is loaded twice it would pointlessly
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	115 redefine functions and cause trouble for autocommands that are added twice.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	116
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	117 The name is recommended to start with "g:loaded_" and then the file name of
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	118 the plugin, literally. The "g:" is prepended to make the variable global, so
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	119 that other places can check whether its functionality is available. Without
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	120 "g:" it would be local to the script.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	121
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	122 Using `finish` stops Vim from reading the rest of the file, it's much quicker
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	123 than using if-endif around the whole file, since Vim would still need to parse
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	124 the commands to find the `endif`.

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	129 Now let's make the plugin more interesting: We will add a mapping that adds a
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	130 correction for the word under the cursor. We could just pick a key sequence
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	131 for this mapping, but the user might already use it for something else. To
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	132 allow the user to define which keys a mapping in a plugin uses, the <Leader>
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	133 item can be used: >

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	137 The "<Plug>TypecorrAdd;" thing will do the work, more about that further on.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	138
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	139 The user can set the "g:mapleader" variable to the key sequence that he wants
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	140 plugin mappings to start with. Thus if the user has done: >
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	141
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	142 g:mapleader = "_"

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	144 the mapping will define "_a". If the user didn't do this, the default value
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	145 will be used, which is a backslash. Then a map for "\a" will be defined.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	146
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	147 Note that <unique> is used, this will cause an error message if the mapping
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	148 already happened to exist. \|:map-<unique>\|
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	149
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	150 But what if the user wants to define his own key sequence? We can allow that
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	151 with this mechanism: >

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	160

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	163 Then the mapped key sequence will be ",c" instead of "_a" or "\a".

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	166 PIECES
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	167
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	168 If a script gets longer, you often want to break up the work in pieces. You
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	169 can use functions or mappings for this. But you don't want these functions
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	170 and mappings to interfere with the ones from other scripts. For example, you
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	171 could define a function Add(), but another script could try to define the same
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	172 function. To avoid this, we define the function local to the script.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	173 Fortunately, in \|Vim9\| script this is the default. In a legacy script you
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	174 would need to prefix the name with "s:".
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	175
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	176 We will define a function that adds a new typing correction: >
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	177
29066 f8e9d5023bf6 Update runtime files Bram Moolenaar <Bram@vim.org> parents: 28933 diff changeset	178 28 def Add(from: string, correct: bool)

f8e9d5023bf6 Update runtime files Bram Moolenaar <Bram@vim.org> parents: 28933 diff changeset	182 34 enddef
28862 82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	183
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	184 Now we can call the function Add() from within this script. If another
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	185 script also defines Add(), it will be local to that script and can only
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	186 be called from that script. There can also be a global g:Add() function,
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	187 which is again another function.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	188
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	189 <SID> can be used with mappings. It generates a script ID, which identifies
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	190 the current script. In our typing correction plugin we use it like this: >
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	191
29066 f8e9d5023bf6 Update runtime files Bram Moolenaar <Bram@vim.org> parents: 28933 diff changeset	192 22 noremap <unique> <script> <Plug>TypecorrAdd; <SID>Add

28862 82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	195
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	196 Thus when a user types "\a", this sequence is invoked: >
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	197
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	198 \a -> <Plug>TypecorrAdd; -> <SID>Add -> :call <SID>Add(...)
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	199
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	200 If another script also maps <SID>Add, it will get another script ID and
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	201 thus define another mapping.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	202
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	203 Note that instead of Add() we use <SID>Add() here. That is because the
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	204 mapping is typed by the user, thus outside of the script context. The <SID>
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	205 is translated to the script ID, so that Vim knows in which script to look for
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	206 the Add() function.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	207
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	208 This is a bit complicated, but it's required for the plugin to work together
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	209 with other plugins. The basic rule is that you use <SID>Add() in mappings and
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	210 Add() in other places (the script itself, autocommands, user commands).
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	211
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	212 We can also add a menu entry to do the same as the mapping: >
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	213
29066 f8e9d5023bf6 Update runtime files Bram Moolenaar <Bram@vim.org> parents: 28933 diff changeset	214 24 noremenu <script> Plugin.Add\ Correction <SID>Add
28862 82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	215
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	216 The "Plugin" menu is recommended for adding menu items for plugins. In this
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	217 case only one item is used. When adding more items, creating a submenu is
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	218 recommended. For example, "Plugin.CVS" could be used for a plugin that offers
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	219 CVS operations "Plugin.CVS.checkin", "Plugin.CVS.checkout", etc.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	220
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	221 Note that in line 28 ":noremap" is used to avoid that any other mappings cause
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	222 trouble. Someone may have remapped ":call", for example. In line 24 we also
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	223 use ":noremap", but we do want "<SID>Add" to be remapped. This is why
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	224 "<script>" is used here. This only allows mappings which are local to the
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	225 script. \|:map-<script>\| The same is done in line 26 for ":noremenu".
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	226 \|:menu-<script>\|
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	227

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	229 <SID> AND <Plug> using-<Plug>
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	230
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	231 Both <SID> and <Plug> are used to avoid that mappings of typed keys interfere
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	232 with mappings that are only to be used from other mappings. Note the
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	233 difference between using <SID> and <Plug>:
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	234
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	235 <Plug> is visible outside of the script. It is used for mappings which the
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	236 user might want to map a key sequence to. <Plug> is a special code
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	237 that a typed key will never produce.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	238 To make it very unlikely that other plugins use the same sequence of
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	239 characters, use this structure: <Plug> scriptname mapname
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	240 In our example the scriptname is "Typecorr" and the mapname is "Add".
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	241 We add a semicolon as the terminator. This results in
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	242 "<Plug>TypecorrAdd;". Only the first character of scriptname and
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	243 mapname is uppercase, so that we can see where mapname starts.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	244
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	245 <SID> is the script ID, a unique identifier for a script.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	246 Internally Vim translates <SID> to "<SNR>123_", where "123" can be any
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	247 number. Thus a function "<SID>Add()" will have a name "<SNR>11_Add()"
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	248 in one script, and "<SNR>22_Add()" in another. You can see this if
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	249 you use the ":function" command to get a list of functions. The
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	250 translation of <SID> in mappings is exactly the same, that's how you
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	251 can call a script-local function from a mapping.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	252
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	253

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	262 The user command is defined only if no command with the same name already
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	263 exists. Otherwise we would get an error here. Overriding the existing user
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	264 command with ":command!" is not a good idea, this would probably make the user

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	272
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	273 When a variable starts with "s:" it is a script variable. It can only be used
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	274 inside a script. Outside the script it's not visible. This avoids trouble
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	275 with using the same variable name in different scripts. The variables will be
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	276 kept as long as Vim is running. And the same variables are used when sourcing
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	277 the same script again. \|s:var\|
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	278
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	279 The nice thing about \|Vim9\| script is that variables are local to the script
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	280 by default. You can prepend "s:" if you like, but you do not need to. And
29066 f8e9d5023bf6 Update runtime files Bram Moolenaar <Bram@vim.org> parents: 28933 diff changeset	281 functions in the script can also use the script variables without a prefix
f8e9d5023bf6 Update runtime files Bram Moolenaar <Bram@vim.org> parents: 28933 diff changeset	282 (they must be declared before the function for this to work).
28862 82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	283
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	284 Script-local variables can also be used in functions, autocommands and user
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	285 commands that are defined in the script. Thus they are the perfect way to
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	286 share information between parts of your plugin, without it leaking out. In
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	287 our example we can add a few lines to count the number of corrections: >

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	297 "count" is declared and initialized to 4 in the script itself. When later
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	298 the Add() function is called, it increments "count". It doesn't matter from
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	299 where the function was called, since it has been defined in the script, it
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	300 will use the local variables from this script.

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	416
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	417 A filetype plugin is like a global plugin, except that it sets options and
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	418 defines mappings for the current buffer only. See \|add-filetype-plugin\| for
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	419 how this type of plugin is used.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	420
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	421 First read the section on global plugins above \|51.1\|. All that is said there
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	422 also applies to filetype plugins. There are a few extras, which are explained
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	423 here. The essential thing is that a filetype plugin should only have an
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	424 effect on the current buffer.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	425

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	428
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	429 If you are writing a filetype plugin to be used by many people, they need a
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	430 chance to disable loading it. Put this at the top of the plugin: >
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	431
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	432 # Only do this when not done yet for this buffer

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	437
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	438 This also needs to be used to avoid that the same plugin is executed twice for
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	439 the same buffer (happens when using an ":edit" command without arguments).

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	441 Now users can disable loading the default plugin completely by making a
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	442 filetype plugin with only these lines: >
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	443

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	447 This does require that the filetype plugin directory comes before $VIMRUNTIME
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	448 in 'runtimepath'!
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	449
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	450 If you do want to use the default plugin, but overrule one of the settings,
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	451 you can write the different setting in a script: >
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	452
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	453 setlocal textwidth=70

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	455 Now write this in the "after" directory, so that it gets sourced after the
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	456 distributed "vim.vim" ftplugin \|after-directory\|. For Unix this would be
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	457 "~/.vim/after/ftplugin/vim.vim". Note that the default plugin will have set
29066 f8e9d5023bf6 Update runtime files Bram Moolenaar <Bram@vim.org> parents: 28933 diff changeset	458 "b:did_ftplugin", it is ignored here.

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	466
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	467 command to set options. And only set options which are local to a buffer (see
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	468 the help for the option to check that). When using `:setlocal` for global
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	469 options or options local to a window, the value will change for many buffers,
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	470 and that is not what a filetype plugin should do.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	471
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	472 When an option has a value that is a list of flags or items, consider using
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	473 "+=" and "-=" to keep the existing value. Be aware that the user may have
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	474 changed an option value already. First resetting to the default value and

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	487 An example of how to define functionality in a filetype plugin: >

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	494 \|hasmapto()\| is used to check if the user has already defined a map to
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	495 <Plug>JavaImport;. If not, then the filetype plugin defines the default
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	496 mapping. This starts with \|<LocalLeader>\|, which allows the user to select
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	497 the key(s) he wants filetype plugin mappings to start with. The default is a
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	498 backslash.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	499 "<unique>" is used to give an error message if the mapping already exists or
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	500 overlaps with an existing mapping.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	501 \|:noremap\| is used to avoid that any other mappings that the user has defined
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	502 interferes. You might want to use ":noremap <script>" to allow remapping
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	503 mappings defined in this script that start with <SID>.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	504
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	505 The user must have a chance to disable the mappings in a filetype plugin,
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	506 without disabling everything. Here is an example of how this is done for a

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	640
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	641 vim9script
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	642 if exists("g:current_compiler")
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	643 finish
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	644 endif
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	645 g:current_compiler = "mine"
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	646
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	647 When you write a compiler file and put it in your personal runtime directory
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	648 (e.g., ~/.vim/compiler for Unix), you set the "current_compiler" variable to
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	649 make the default file skip the settings.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	650 :CompilerSet
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	651 The second mechanism is to use ":set" for ":compiler!" and ":setlocal" for
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	652 ":compiler". Vim defines the ":CompilerSet" user command for this. However,
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	653 older Vim versions don't, thus your plugin should define it then. This is an
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	654 example: >
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	655
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	656 if exists(":CompilerSet") != 2
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	657 command -nargs=* CompilerSet setlocal <args>
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	658 endif
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	659 CompilerSet errorformat& " use the default 'errorformat'

82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	662 When you write a compiler plugin for the Vim distribution or for a system-wide
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	663 runtime directory, use the mechanism mentioned above. When
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	664 "current_compiler" was already set by a user plugin nothing will be done.
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	665
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	666 When you write a compiler plugin to overrule settings from a default plugin,
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	667 don't check "current_compiler". This plugin is supposed to be loaded
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	668 last, thus it should be in a directory at the end of 'runtimepath'. For Unix
82244cfc4694 Update runtime files, new color schemes Bram Moolenaar <Bram@vim.org> parents: diff changeset	669 that could be ~/.vim/after/compiler.
