Automatic Vim Downloading Script

[Iguleder]

Here's a simple script I wrote for detecting and downloading the latest Vim and patching it with all bug-fix patches. Currently, it has 315 patches ... too much to download and apply manually. It also comes with an "update" script, which simple checks what Vim version is installed, compares it with the latest available and asks the user whether to run the compilation script or not.

To save space, it downloads a patch, applies it and erases it immediately. After patching, it configures with my preferred flags, so change them as you wish. After configuring, it compiles it and installs to ~/vim-version-arch (should be "vim-7.2.315-i486" at the time of writing). Then, it creates a TCZ from that directory.

I haven't tested it with Tiny Core's BusyBox, but I tested the downloading and patching part with my distro (which uses a newer BusyBox and has no GCC) - it worked. It might be useful, as someone might be interested in turning this script into an automatic downloading, patching, compiling and packing script. The whole thing is experimental, don't blame me if something gets messed up, although I don't think something will.

Pay attention to the "force a specific version" part: uncomment it, put the right numbers and delete the version detection part to use it.

# detect latest patch number

I require bash for the for loop.  I don't know if people need lang and extras.  I might submit gvim, though.
Thanks.  

edit: submitted with extra patches; included gvim w/ menu/icon.; included extras/removed lang files (could be put in separate extension).  

edit: lang files submitted in separate extension

FYI: There are a number of ways of getting vim patches. In the previous version I used AAP.  This works nicely, though.

... The Vim sources: I recommend to download the full set of sources, even sources never needed on Unix. This way you will later be able to apply all patches without problems ...

The full sources are needed to make the whole process silent.
