14Getscript is a plugin that simplifies retrieval of the latest versions of the
15scripts that you yourself use!  Typing |:GLVS| will invoke getscript; it will
16then use the <GetLatestVimScripts.dat> (see |GetLatestVimScripts_dat|) file to
17get the latest versions of scripts listed therein from http://vim.sf.net/.

352. GetLatestVimScripts -- Getting Started		*getscript-start*
36						*getlatestvimscripts-install*
37
38	VERSION FROM VIM DISTRIBUTION			*glvs-dist-install*
39
40Vim 7.0 does not include the GetLatestVimScripts.dist file which
41serves as an example and a template.  So, you'll need to create
42your own!  See |GetLatestVimScripts_dat|.
43
44	VERSION FROM VIM SF NET				*glvs-install*
45
46NOTE: The last step, that of renaming/moving the GetLatestVimScripts.dist
47file, is for those who have just downloaded GetLatestVimScripts.tar.bz2 for
48the first time.
49
50The GetLatestVimScripts.dist file serves as an example and a template for your
51own personal list.  Feel free to remove all the scripts mentioned within it;
52the "important" part of it is the first two lines.
53
54Your computer needs to have wget for GetLatestVimScripts to do its work.
55
56	1. if compressed:  gunzip getscript.vba.gz
57	2. Unix:
58		vim getscript.vba
59		:so %
60		:q
61		cd ~/.vim/GetLatest
62		mv GetLatestVimScripts.dist GetLatestVimScripts.dat
63		(edit GetLatestVimScripts.dat to install your own personal
64		list of desired plugins -- see |GetLatestVimScripts_dat|)
65
66	3. Windows:
67		vim getscript.vba
68		:so %
69		:q
70		cd **path-to-vimfiles**/GetLatest
71		mv GetLatestVimScripts.dist GetLatestVimScripts.dat
72		(edit GetLatestVimScripts.dat to install your own personal
73		list of desired plugins -- see |GetLatestVimScripts_dat|)
74
75
76==============================================================================
773. GetLatestVimScripts Usage				*glvs-usage* *:GLVS*
78
79Unless its been defined elsewhere, >
80	:GLVS
81will invoke GetLatestVimScripts().  If some other plugin has defined that
82command, then you may type
83>
84	:GetLatestVimScripts
85<
86The script will attempt to update and, if permitted, will automatically
87install scripts from http://vim.sourceforge.net/.  To do so it will peruse a
88file,
89>
90	.vim/GetLatest/GetLatestVimScripts.dat                    (unix)
91<
92or >
93	..wherever..\vimfiles\GetLatest\GetLatestVimScripts.dat   (windows)
94(see |glvs-data|), and examine plugins in your [.vim|vimfiles]/plugin
95directory (see |glvs-plugins|).
96
97Scripts which have been downloaded will appear in the
98~/.vim/GetLatest (unix) or ..wherever..\vimfiles\GetLatest (windows)
99subdirectory.  GetLatestVimScripts will attempt to automatically
100install them if you have the following line in your <.vimrc>: >
101
102	let g:GetLatestVimScripts_allowautoinstall=1
103
104The <GetLatestVimScripts.dat> file will be automatically be updated to
105reflect the latest version of script(s) so downloaded.
106(also see |glvs-options|)
107
108
109==============================================================================
1104. GetLatestVimScripts Data File		*getscript-data* *glvs-data*
111 						*:GetLatestVimScripts_dat*
112The data file <GetLatestVimScripts.dat> must have for its first two lines
113the following text:
114>
115	ScriptID SourceID Filename
116	--------------------------
117<
118Following those two lines are three columns; the first two are numeric
119followed by a text column.  The GetLatest/GetLatestVimScripts.dist file
120contains an example of such a data file.  Anything following a #... is
121ignored, so you may embed comments in the file.
122
123The first number on each line gives the script's ScriptID.  When you're about
124to use a web browser to look at scripts on http://vim.sf.net/, just before you
125click on the script's link, you'll see a line resembling
126
127	http://vim.sourceforge.net/scripts/script.php?script_id=40
128
129The "40" happens to be a ScriptID that GetLatestVimScripts needs to
130download the associated page.
131
132The second number on each line gives the script's SourceID.  The SourceID
133records the count of uploaded scripts as determined by vim.sf.net; hence it
134serves to indicate "when" a script was uploaded.  Setting the SourceID to 1
135insures that GetLatestVimScripts will assume that the script it has is
136out-of-date.
137
138The SourceID is extracted by GetLatestVimScripts from the script's page on
139vim.sf.net; whenever it's greater than the one stored in the
140GetLatestVimScripts.dat file, the script will be downloaded
141(see |GetLatestVimScripts_dat|).
142
143If your script's author has included a special comment line in his/her plugin,
144the plugin itself will be used by GetLatestVimScripts to build your
145<GetLatestVimScripts.dat> file, including any dependencies on other scripts it
146may have.  As an example, consider: >
147
148	" GetLatestVimScripts: 884  1 :AutoInstall: AutoAlign.vim
149
150This comment line tells getscript.vim to check vimscript #884 and that the
151script is automatically installable.  Getscript will also use this line to
152help build the GetLatestVimScripts.dat file, by including a line such as: >
153
154	884 1 AutoAlign.vim
155<
156in it an AutoAlign.vim line isn't already in GetLatestVimScripts.dat file.
157See |glvs-plugins| for more.  Thus, GetLatestVimScripts thus provides a
158comprehensive ability to keep your plugins up-to-date!
159
160						*GetLatestVimScripts_dat*
161As an example of a <GetLatestVimScripts.dat> file:
162>
163    ScriptID SourceID Filename
164    --------------------------
165    294 1 Align.vim
166    120 2 decho.vim
167     40 3 DrawIt.tar.gz
168    451 4 EasyAccents.vim
169    195 5 engspchk.vim
170    642 6 GetLatestVimScripts.vim
171    489 7 Manpageview.vim
172<
173Note: the first two lines are required, but essentially act as comments.
174
175
176==============================================================================
1775. GetLatestVimScripts Friendly Plugins	*getscript-plugins* *glvs-plugins*
178
179If a plugin author includes the following comment anywhere in their plugin,
180GetLatestVimScripts will find it and use it to automatically build the user's
181GetLatestVimScripts.dat files:
182>
183	                         src_id
184	                            v
185	" GetLatestVimScripts: ### ### yourscriptname
186	                        ^
187	                    scriptid
188<
189As an author, you should include such a line in to refer to your own script
190plus any additional lines describing any plugin dependencies it may have.
191Same format, of course!
192
193If your command is auto-installable (see |glvs-autoinstall|), and most scripts
194are, then you may include :AutoInstall: at the start of "yourscriptname".
195
196GetLatestVimScripts commands for those scripts are then appended, if not
197already present, to the user's GetLatest/GetLatestVimScripts.dat file.  Its a
198relatively painless way to automate the acquisition of any scripts your
199plugins depend upon.
200
201Now, as an author, you probably don't want GetLatestVimScripts to download
202your own scripts for you yourself, thereby overwriting your not-yet-released
203hard work.  GetLatestVimScripts provides a solution for this:  put
204>
205	0 0 yourscriptname
206<
207into your <GetLatestVimScripts.dat> file and GetLatestVimScripts will skip
208examining the "yourscriptname" scripts for those GetLatestVimScripts comment
209lines.  As a result, those lines won't be inadvertently installed into your
210<GetLatestVimScripts.dat> file and subsequently used to download your own
211scripts.  This is especially important to do if you've included the
212:AutoInstall: option.
213
214Be certain to use the same "yourscriptname" in the "0 0 yourscriptname" line
215as you've used in your GetLatestVimScripts comment!
216
217
218==============================================================================
2196. GetLatestVimScripts AutoInstall			*getscript-autoinstall*
220							*glvs-autoinstall*
221
222GetLatestVimScripts now supports "AutoInstall".  Not all scripts are
223supportive of auto-install, as they may have special things you need to do to
224install them (please refer to the script's "install" directions).  On the
225other hand, most scripts will be auto-installable.
226
227To let GetLatestVimScripts do an autoinstall, the data file's comment field
228should begin with (surrounding blanks are ignored): >
229
230	:AutoInstall:
231<
232Both colons are needed, and it should begin the comment (yourscriptname)
233field.
234
235One may prevent any autoinstalling by putting the following line in your
236<.vimrc>: >
237
238	let g:GetLatestVimScripts_allowautoinstall= 0
239<
240With :AutoInstall: enabled, as it is by default, files which end with
241
242	---.tar.bz2  : decompressed & untarred in .vim/ directory
243	---.vba.bz2  : decompressed in .vim/ directory, then vimball handles it
244	---.vim.bz2  : decompressed & moved into .vim/plugin directory
245	---.tar.gz   : decompressed & untarred in .vim/ directory
246	---.vba.gz   : decompressed in .vim/ directory, then vimball handles it
247	---.vim.gz   : decompressed & moved into .vim/plugin directory
248	---.vba      : unzipped in .vim/ directory
249	---.vim      : moved to .vim/plugin directory
250	---.zip      : unzipped in .vim/ directory
251
252and which merely need to have their components placed by the untar/gunzip or
253move-to-plugin-directory process should be auto-installable.  Vimballs, of
254course, should always be auto-installable.
255
256When is a script not auto-installable?  Let me give an example:
257
258	.vim/after/syntax/blockhl.vim
259
260The <blockhl.vim> script provides block highlighting for C/C++ programs; it is
261available at:
262
263	http://vim.sourceforge.net/scripts/script.php?script_id=104
264
265Currently, vim's after/syntax only supports by-filetype scripts (in
266blockhl.vim's case, that's after/syntax/c.vim).  Hence, auto-install would
267possibly overwrite the current user's after/syntax/c.vim file.
268
269In my own case, I use <aftersyntax.vim> (renamed to after/syntax/c.vim) to
270allow a after/syntax/c/ directory:
271
272	http://vim.sourceforge.net/scripts/script.php?script_id=1023
273
274The script allows multiple syntax files to exist separately in the
275after/syntax/c subdirectory.  I can't bundle aftersyntax.vim in and build an
276appropriate tarball for auto-install because of the potential for the
277after/syntax/c.vim contained in it to overwrite a user's c.vim.
278
279
280==============================================================================
2817. GetLatestVimScripts Options					*glvs-options*
282>
283	g:GetLatestVimScripts_wget
284<	default= "wget"
285		This variable holds the name of the command for obtaining
286		scripts.
287>
288	g:GetLatestVimScripts_options
289<	default= "-q -O"
290		This variable holds the options to be used with the
291		g:GetLatestVimScripts_wget command.
292>
293 	g:getLatestVimScripts_allowautoinstall
294<	default= 1
295		This variable indicates whether GetLatestVimScripts is allowed
296		to attempt to automatically install scripts.  Note that it
297		doesn't understand vimballs (yet).  Furthermore, the plugin
298		author has to have explicitly indicated that his/her plugin
299		is automatically installable.
300
301
302==============================================================================
3038. GetLatestVimScripts Algorithm		*glvs-algorithm* *glvs-alg*
304
305The Vim sourceforge page dynamically creates a page by keying off of the
306so-called script-id.  Within the webpage of
307
308	http://vim.sourceforge.net/scripts/script.php?script_id=40
309
310is a line specifying the latest source-id (src_id).  The source identifier
311numbers are always increasing, hence if the src_id is greater than the one
312recorded for the script in GetLatestVimScripts then it's time to download a
313newer copy of that script.
314
315GetLatestVimScripts will then download the script and update its internal
316database of script ids, source ids, and scriptnames.
317
318The AutoInstall process will:
319
320	Move the file from GetLatest/ to the following directory
321		Unix   : $HOME/.vim
322		Windows: $HOME\vimfiles
323	if the downloaded file ends with ".bz2"
324		bunzip2 it
325	else if the downloaded file ends with ".gz"
326		gunzip it
327	if the resulting file ends with ".zip"
328		unzip it
329	else if the resulting file ends with ".tar"
330		tar -oxvf it
331	else if the resulting file ends with ".vim"
332		move it to the plugin subdirectory
333

354    Apr 01, 2005   * when downloading errors occurred, GLVS was
355                     terminating early.  It now just goes on to trying
356                     the next script (after trying three times to
357                     download a script description page)
358    Apr 20, 2005   * bugfix - when a failure to download occurred,
359                     GetLatestVimScripts would stop early and claim that
360                     everything was current.  Fixed.
361v17 Aug 25, 2004 : * g:GetLatestVimScripts_allowautoinstall, which

368v14 Aug 24, 2004 : * bugfix -- helptags was using dotvim, rather than
369                     s:dotvim.  Fixed.
370v13 Aug 23, 2004 : * will skip downloading a file if its scriptid or srcid
371                     is zero.  Useful for script authors; that way their
372                     own GetLatestVimScripts activity won't overwrite
373                     their scripts.
374v12 Aug 23, 2004 : * bugfix - a "return" got left in the distribution that
375                     was intended only for testing.  Removed, now works.
376                   * :AutoInstall: implemented
377v11 Aug 20, 2004 : * GetLatestVimScripts is now a plugin:
378                   * :GetLatestVimScripts command
379                   * (runtimepath)/GetLatest/GetLatestVimScripts.dat
380                     now holds scripts that need updating
381v10 Apr 19, 2004 : * moved history from script to doc
382v9  Jan 23, 2004 :   windows (win32/win16/win95) will use
383                     double quotes ("") whereas other systems will use
384                     single quotes ('') around the urls in calls via wget
385v8  Dec 01, 2003 :   makes three tries at downloading
386v7  Sep 02, 2003 :   added error messages if "Click on..." or "src_id="
387                     not found in downloaded webpage
388                     Uses t_ti, t_te, and rs to make progress visible
389v6  Aug 06, 2003 :   final status messages now display summary of work

391                       "Everything was current")
392                     Now GetLatestVimScripts is careful about downloading
393                     GetLatestVimScripts.vim itself!
394                     (goes to <NEW_GetLatestVimScripts.vim>)
395v5  Aug 04, 2003 :   missing an endif near bottom
396v4  Jun 17, 2003 :   redraw! just before each "considering" message
397v3  May 27, 2003 :   Protects downloaded files from errant shell
398                     expansions with single quotes: '...'
399v2  May 14, 2003 :   extracts name of item to be obtained from the
400                     script file.  Uses it instead of comment field
401                     for output filename; comment is used in the
402                     "considering..." line and is now just a comment!
403                   * Fixed a bug: a string-of-numbers is not the
404                     same as a number, so I added zero to them
405                     and they became numbers.  Fixes comparison.
