2. GetLatestVimScripts Usage *getlatestvimscripts* *getscript* *glvs*
While in vim, type
>
:GetLatestVimScripts
<
Unless its been defined elsewhere,
>
:GLVS
<
will also work.
The script will attempt to update and, if so directed, automatically
install scripts from http://vim.sourceforge.net/. To do so it will
peruse a file, [.vim|vimfiles]/GetLatest/GetLatestVimScripts.dat
(see |glvs-data|), and examine plugins in your [.vim|vimfiles]/plugin
directory (see |glvs-plugins|).
Scripts which have been downloaded will appear in the .../GetLatest
subdirectory.
The <GetLatestVimScripts.dat> file will be automatically be updated to
reflect the latest version of script(s) so downloaded.
==============================================================================
3. GetLatestVimScripts Data File *getlatestvimscripts-data* *glvs-data*
The Data file has a header which should appear as:
>
ScriptID SourceID Filename
--------------------------
<
Below that are three columns; the first two are numeric followed by a
text column.
The first number on each line gives the script's ScriptID. When
you're about to use a web browser to look at scripts on
http://vim.sf.net/, just before you click on the script's link, you'll
see a line resembling
http://vim.sourceforge.net/scripts/script.php?script_id=40
The "40" happens to be a ScriptID that GetLatestVimScripts needs to
download the associated page.
The second number on each line gives the script's SourceID. The
SourceID records the count of uploaded scripts as determined by
vim.sf.net; hence it serves to indicate "when" a script was uploaded.
Setting the SourceID to 1 insures that GetLatestVimScripts will assume
that the script it has is out-of-date.
The SourceID is extracted by GetLatestVimScripts from the script's
page on vim.sf.net; whenever its greater than the one stored in the
GetLatestVimScripts.dat file, the script will be downloaded.
If your script's author has included a special comment line in his/her
plugin, the plugin itself will be used by GetLatestVimScripts to build
your <GetLatestVimScripts.dat> file, including any dependencies on
other scripts it may have.
If your comment field begins with :AutoInstall:, GetLatestVimScripts
will attempt to automatically install the script. Thus,
GetLatestVimScripts thus provides a comprehensive ability to keep your
plugins up-to-date!
==============================================================================
4. GetLatestVimScripts Plugins *getlatestvimscripts-plugins* *glvs-plugins*
If a plugin author includes the following comment anywhere in their
plugin, GetLatestVimScripts will find it and use it to build user's
GetLatestVimScripts.dat files:
>
src_id
v
" GetLatestVimScripts: ### ### yourscriptname
^
scriptid
<
As an author, you should include such a line in to refer to your own
script plus any additional lines describing any plugin dependencies it
may have. Same format, of course!
If your command is auto-installable (see |glvs-autoinstall|), and most
scripts are, then you may include :AutoInstall: at the start of
"yourscriptname".
GetLatestVimScript commands for those scripts are then appended, if
not already present, to the user's GetLatest/GetLatestVimScripts.dat
file. Its a relatively painless way to automate the acquisition of
any scripts your plugins depend upon.
Now, as an author, you probably don't want GetLatestVimScripts to
download your own scripts for you yourself, thereby overwriting your
not-yet-released hard work. GetLatestVimScripts provides a solution
for this: put
>
0 0 yourscriptname
<
into your <GetLatestVimScripts.dat> file and GetLatestVimScripts will
skip examining the "yourscriptname" scripts for those
GetLatestVimScript comment lines. As a result, those lines won't be
inadvertently installed into your <GetLatestVimScripts.dat> file and
subsequently used to download your own scripts. This is especially
important to do if you've included the :AutoInstall: option.
Be certain to use the same "yourscriptname" in the "0 0
yourscriptname" line as you've used in your GetLatestVimScript
comment!
==============================================================================
5. GetLatestVimScripts AutoInstall *getlatestvimscripts-autoinstall*
*glvs-autoinstall*
GetLatestVimScripts now supports "AutoInstall". Not all scripts are
supportive of auto-install, as they may have special things you need
to do to install them (please refer to the script's "install"
directions). On the other hand, most scripts will be
auto-installable.
To let GetLatestVimScripts do an autoinstall, the data file's comment
field should begin with (surrounding blanks are ignored):
:AutoInstall:
Both colons are needed, and it should begin the comment
(yourscriptname) field.
One may prevent any autoinstalling by putting the following line
in your <.vimrc>:
>
let g:GetLatestVimScripts_allowautoinstall= 0
<
With :AutoInstall: enabled, as it is by default, files which end with
---.tar.bz2 : decompressed and untarred in [.vim|vimfiles] directory
---.tar.gz : decompressed and untarred in [.vim|vimfiles] directory
---.vim.bz2 : decompressed and moved to the .vim/plugin directory
---.vim.gz : decompressed and moved to the .vim/plugin directory
---.zip : unzipped in [.vim|vimfiles] directory
---.vim : moved to [.vim|vimfiles]/plugin directory
and which merely need to have their components placed by the
untar/gunzip or move-to-plugin-directory process should be
auto-installable.
When is a script not auto-installable? Let me give an example:
>
[.vim|vimfiles]/after/syntax/blockhl.vim
<
The <blockhl.vim> script provides block highlighting for C/C++
programs; it is available at:
>
http://vim.sourceforge.net/scripts/script.php?script_id=104
<
Currently, vim's after/syntax only supports by-filetype scripts (in
blockhl.vim's case, that's after/syntax/c.vim). Hence, auto-install
would possibly overwrite the current user's after/syntax/c.vim file.
In my own case, I use <aftersyntax.vim> (renamed to
after/syntax/c.vim) to allow a after/syntax/c/ directory:
>
http://vim.sourceforge.net/scripts/script.php?script_id=1023
<
The script allows multiple syntax files to exist separately in the
after/syntax/c subdirectory. I can't bundle aftersyntax.vim in and
build an appropriate tarball for auto-install because of the potential
for the after/syntax/c.vim contained in it to overwrite a user's
c.vim.
==============================================================================
6. GetLatestVimScripts Algorithm *getlatestvimscripts-algorithm*
*glvs-alg*
The Vim sourceforge page dynamically creates a page by keying off of
the so-called script-id. Within the webpage of
http://vim.sourceforge.net/scripts/script.php?script_id=40
is a line specifying the latest source-id (src_id). The source
identifier numbers are always increasing, hence if the src_id is
greater than the one recorded for the script in GetLatestVimScripts
then its time to download a newer copy of that script.
GetLatestVimScripts will then download the script and update its
internal database of script ids, source ids, and scriptnames.
The AutoInstall process will:
Move the file from GetLatest/ to the following directory
Unix : $HOME/.vim
Windows: $HOME\vimfiles
if the downloaded file ends with ".bz2"
bunzip2 it
else if the downloaded file ends with ".gz"
gunzip it
if the resulting file ends with ".zip"
unzip it
else if the resulting file ends with ".tar"
tar -oxvf it
else if the resulting file ends with ".vim"
move it to the plugin subdirectory
==============================================================================
7. GetLatestVimScripts History *getlatestvimscripts-history* *glvs-hist*
v20 Dec 23, 2005 : * Eric Haarbauer found&fixed a bug with unzip use;
unzip needs the -o flag to overwrite.
v19 Nov 28, 2005 : * v18's GetLatestVimScript line accessed the wrong
script! Fixed.
v18 Mar 21, 2005 : * bugfix to automatic database construction
* bugfix - nowrapscan caused an error
(tnx to David Green for the fix)
Apr 01, 2005 * if shell is bash, "mv" instead of "ren" used in
:AutoInstall:s, even though its o/s is windows
Apr 01, 2005 * when downloading errors occurred, GLVS was
terminating early. It now just goes on to trying
the next script (after trying three times to
download a script description page)
Apr 20, 2005 * bugfix - when a failure to download occurred,
GetLatestVimScripts would stop early and claim that
everything was current. Fixed.
v17 Aug 25, 2004 : * g:GetLatestVimScripts_allowautoinstall, which
defaults to 1, can be used to prevent all
:AutoInstall:
v16 Aug 25, 2004 : * made execution of bunzip2/gunzip/tar/zip silent
* fixed bug with :AutoInstall: use of helptags
v15 Aug 24, 2004 : * bugfix: the "0 0 comment" download prevention wasn't
always preventing downloads (just usually). Fixed.
v14 Aug 24, 2004 : * bugfix -- helptags was using dotvim, rather than
s:dotvim. Fixed.
v13 Aug 23, 2004 : * will skip downloading a file if its scriptid or srcid
is zero. Useful for script authors; that way their
own GetLatestVimScripts activity won't overwrite
their scripts.
v12 Aug 23, 2004 : * bugfix - a "return" got left in the distribution that
was intended only for testing. Removed, now works.
* :AutoInstall: implemented
v11 Aug 20, 2004 : * GetLatestVimScripts is now a plugin:
* :GetLatestVimScripts command
* (runtimepath)/GetLatest/GetLatestVimScripts.dat
now holds scripts that need updating
v10 Apr 19, 2004 : * moved history from script to doc
v9 Jan 23, 2004 : windows (win32/win16/win95) will use
double quotes ("") whereas other systems will use
single quotes ('') around the urls in calls via wget
v8 Dec 01, 2003 : makes three tries at downloading
v7 Sep 02, 2003 : added error messages if "Click on..." or "src_id="
not found in downloaded webpage
Uses t_ti, t_te, and rs to make progress visible
v6 Aug 06, 2003 : final status messages now display summary of work
( "Downloaded someqty scripts" or
"Everything was current")
Now GetLatestVimScripts is careful about downloading
GetLatestVimScripts.vim itself!
(goes to <NEW_GetLatestVimScripts.vim>)
v5 Aug 04, 2003 : missing an endif near bottom
v4 Jun 17, 2003 : redraw! just before each "considering" message
v3 May 27, 2003 : Protects downloaded files from errant shell
expansions with single quotes: '...'
v2 May 14, 2003 : extracts name of item to be obtained from the
script file. Uses it instead of comment field
for output filename; comment is used in the
"considering..." line and is now just a comment!
* Fixed a bug: a string-of-numbers is not the
same as a number, so I added zero to them
and they became numbers. Fixes comparison.
