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 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 Setting the SourceID to 1 insures that GetLatestVimScripts will assume that the script it has is out-of-date.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 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 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 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 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 (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 ) 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. ============================================================================== vim:tw=78:ts=8:ft=help
