| 7 *install* | |
| 8 Before you can use Vim you have to install it. Depending on your system it's | |
| 9 simple or easy. This chapter gives a few hints and also explains how | |
| 10 upgrading to a new version is done. | |

| 21 ============================================================================== | |
| 22 *90.1* Unix | |
| 23 | |
| 24 First you have to decide if you are going to install Vim system-wide or for a | |
| 25 single user. The installation is almost the same, but the directory where Vim | |
| 26 is installed in differs. | |
| 27 For a system-wide installation the base directory "/usr/local" is often | |
| 28 used. But this may be different for your system. Try finding out where other | |
| 29 packages are installed. | |
| 30 When installing for a single user, you can use your home directory as the | |
| 31 base. The files will be placed in subdirectories like "bin" and "shared/vim". | |
| 32 | |
| 33 | |
| 34 FROM A PACKAGE | |
| 35 | |
| 36 You can get precompiled binaries for many different UNIX systems. There is a | |
| 37 long list with links on this page: | |
| 38 | |
| 39 http://www.vim.org/binaries.html ~ | |
| 40 | |
| 41 Volunteers maintain the binaries, so they are often out of date. It is a | |
| 42 good idea to compile your own UNIX version from the source. Also, creating | |
| 43 the editor from the source allows you to control which features are compiled. | |
| 44 This does require a compiler though. | |
| 45 | |
| 46 If you have a Linux distribution, the "vi" program is probably a minimal | |
| 47 version of Vim. It doesn't do syntax highlighting, for example. Try finding | |
| 48 another Vim package in your distribution, or search on the web site. | |
| 49 | |
| 50 | |
| 51 FROM SOURCES | |
| 52 | |
| 53 To compile and install Vim, you will need the following: | |
| 54 | |
| 55 - A C compiler (GCC preferred) | |
| 56 - The GZIP program (you can get it from www.gnu.org) | |
| 57 - The Vim source and runtime archives | |
| 58 | |
| 59 To get the Vim archives, look in this file for a mirror near you, this should | |
| 60 provide the fastest download: | |
| 61 | |
| 62 ftp://ftp.vim.org/pub/vim/MIRRORS ~ | |
| 63 | |
| 64 Or use the home site ftp.vim.org, if you think it's fast enough. Go to the | |
| 65 "unix" directory and you'll find a list of files there. The version number is | |
| 66 embedded in the file name. You will want to get the most recent version. | |
| 19116 | 67 You can get the files for Unix in one big archive that contains everything: |
| 7 | 68 |
| 19116 | 69 vim-8.2.tar.bz2 ~ |
| 7 | 70 |
| 19116 | 71 You need the bzip2 program to uncompress it. |
| 7 | 72 |
| 73 | |
| 74 COMPILING | |
| 75 | |
| 76 First create a top directory to work in, for example: > | |
| 77 | |
| 78 mkdir ~/vim | |
| 79 cd ~/vim | |
| 80 | |
| 19116 | 81 Then unpack the archives there. You can unpack it like this: > |
| 7 | 82 |
| 19116 | 83 tar xf path/vim-8.2.tar.bz2 |
| 7 | 84 |
| 19116 | 85 If your tar command doesn't support bz2 directly: > |
| 7 | 86 |
| 19116 | 87 bzip2 -d -c path/vim-8.2.tar.bz2 | tar xf - |
| 7 | 88 |
| 19116 | 89 Change "path" to where you have downloaded the file. |
| 7 | 90 If you are satisfied with getting the default features, and your environment |
| 91 is setup properly, you should be able to compile Vim with just this: > | |
| 92 | |
| 19116 | 93 cd vim82/src |
| 7 | 94 make |
| 95 | |
| 96 The make program will run configure and compile everything. Further on we | |
| 97 will explain how to compile with different features. | |
| 98 If there are errors while compiling, carefully look at the error messages. | |
| 99 There should be a hint about what went wrong. Hopefully you will be able to | |
| 100 correct it. You might have to disable some features to make Vim compile. | |
| 101 Look in the Makefile for specific hints for your system. | |
| 102 | |
| 103 | |
| 104 TESTING | |
| 105 | |
| 106 Now you can check if compiling worked OK: > | |
| 107 | |
| 108 make test | |
| 109 | |
| 110 This will run a sequence of test scripts to verify that Vim works as expected. | |
| 111 Vim will be started many times and all kinds of text and messages flash by. | |
| 112 If it is alright you will finally see: | |
| 113 | |
| 114 test results: ~ | |
| 115 ALL DONE ~ | |

| 124 | |
| 125 INSTALLING | |
| 126 *install-home* | |
| 127 If you want to install in your home directory, edit the Makefile and search | |
| 128 for a line: | |
| 129 | |
| 130 #prefix = $(HOME) ~ | |
| 131 | |
| 132 Remove the # at the start of the line. | |
| 133 When installing for the whole system, Vim has most likely already selected | |
| 134 a good installation directory for you. You can also specify one, see below. | |
| 135 You need to become root for the following. | |
| 136 | |
| 137 To install Vim do: > | |
| 138 | |
| 139 make install | |
| 140 | |
| 141 That should move all the relevant files to the right place. Now you can try | |
| 142 running vim to verify that it works. Use two simple tests to check if Vim can | |
| 143 find its runtime files: > | |
| 144 | |
| 145 :help | |
| 146 :syntax enable | |
| 147 | |
| 148 If this doesn't work, use this command to check where Vim is looking for the | |
| 149 runtime files: > | |
| 150 | |
| 151 :echo $VIMRUNTIME | |
| 152 | |
| 153 You can also start Vim with the "-V" argument to see what happens during | |
| 154 startup: > | |
| 155 | |
| 156 vim -V | |
| 157 | |
| 158 Don't forget that the user manual assumes you Vim in a certain way. After | |
| 159 installing Vim, follow the instructions at |not-compatible| to make Vim work | |
| 160 as assumed in this manual. | |
| 161 | |
| 162 | |
| 163 SELECTING FEATURES | |
| 164 | |
| 165 Vim has many ways to select features. One of the simple ways is to edit the | |
| 166 Makefile. There are many directions and examples. Often you can enable or | |
| 167 disable a feature by uncommenting a line. | |
| 168 An alternative is to run "configure" separately. This allows you to | |
| 169 specify configuration options manually. The disadvantage is that you have to | |
| 170 figure out what exactly to type. | |
| 171 Some of the most interesting configure arguments follow. These can also be | |
| 172 enabled from the Makefile. | |
| 173 | |
| 174 --prefix={directory} Top directory where to install Vim. | |
| 175 | |
| 176 --with-features=tiny Compile with many features disabled. | |
| 177 --with-features=small Compile with some features disabled. | |
| 178 --with-features=big Compile with more features enabled. | |
| 179 --with-features=huge Compile with most features enabled. | |
| 180 See |+feature-list| for which feature | |
| 181 is enabled in which case. | |
| 182 | |
| 183 --enable-perlinterp Enable the Perl interface. There are | |
| 184 similar arguments for ruby, python and | |
| 185 tcl. | |
| 186 | |
| 187 --disable-gui Do not compile the GUI interface. | |
| 188 --without-x Do not compile X-windows features. | |
| 189 When both of these are used, Vim will | |
| 190 not connect to the X server, which | |
| 191 makes startup faster. | |
| 192 | |
| 193 To see the whole list use: > | |
| 194 | |
| 195 ./configure --help | |
| 196 | |
| 197 You can find a bit of explanation for each feature, and links for more | |
| 198 information here: |feature-list|. | |
| 199 For the adventurous, edit the file "feature.h". You can also change the | |
| 200 source code yourself! | |
| 201 | |
| 202 ============================================================================== | |
| 203 *90.2* MS-Windows | |
| 204 | |
| 205 There are two ways to install the Vim program for Microsoft Windows. You can | |
| 206 uncompress several archives, or use a self-installing big archive. Most users | |
| 207 with fairly recent computers will prefer the second method. For the first | |
| 208 one, you will need: | |
| 209 | |
| 210 - An archive with binaries for Vim. | |
| 211 - The Vim runtime archive. | |
| 212 - A program to unpack the zip files. | |
| 213 | |
| 214 To get the Vim archives, look in this file for a mirror near you, this should | |
| 215 provide the fastest download: | |
| 216 | |
| 217 ftp://ftp.vim.org/pub/vim/MIRRORS ~ | |
| 218 | |
| 219 Or use the home site ftp.vim.org, if you think it's fast enough. Go to the | |
| 220 "pc" directory and you'll find a list of files there. The version number is | |
| 221 embedded in the file name. You will want to get the most recent version. | |
| 19116 | 222 We will use "82" here, which is version 8.2. |
| 7 | 223 |
| 19116 | 224 gvim82.exe The self-installing archive. |
| 7 | 225 |
| 226 This is all you need for the second method. Just launch the executable, and | |
| 227 follow the prompts. | |
| 228 | |
| 229 For the first method you must chose one of the binary archives. These are | |
| 230 available: | |
| 231 | |
| 19116 | 232 gvim82.zip The normal MS-Windows GUI version. |
| 233 gvim82ole.zip The MS-Windows GUI version with OLE support. | |
| 7 | 234 Uses more memory, supports interfacing with |
| 235 other OLE applications. | |
| 19116 | 236 vim82w32.zip 32 bit MS-Windows console version. |
| 7 | 237 |
| 238 You only need one of them. Although you could install both a GUI and a | |
| 239 console version. You always need to get the archive with runtime files. | |
| 240 | |
| 19116 | 241 vim82rt.zip The runtime files. |
| 7 | 242 |
| 243 Use your un-zip program to unpack the files. For example, using the "unzip" | |
| 244 program: > | |
| 245 | |
| 246 cd c:\ | |
| 19116 | 247 unzip path\gvim82.zip |
| 248 unzip path\vim82rt.zip | |
| 7 | 249 |
| 19116 | 250 This will unpack the files in the directory "c:\vim\vim82". If you already |
| 7 | 251 have a "vim" directory somewhere, you will want to move to the directory just |
| 252 above it. | |
| 19116 | 253 Now change to the "vim\vim82" directory and run the install program: > |
| 7 | 254 |
| 255 install | |
| 256 | |
| 257 Carefully look through the messages and select the options you want to use. | |
| 258 If you finally select "do it" the install program will carry out the actions | |
| 259 you selected. | |
| 260 The install program doesn't move the runtime files. They remain where you | |
| 261 unpacked them. | |
| 262 | |
| 263 In case you are not satisfied with the features included in the supplied | |
| 264 binaries, you could try compiling Vim yourself. Get the source archive from | |
| 265 the same location as where the binaries are. You need a compiler for which a | |
| 19116 | 266 makefile exists. Microsoft Visual C, MinGW and Cygwin compilers can be used. |
| 267 Check the file src/INSTALLpc.txt for hints. | |
| 7 | 268 |
| 269 ============================================================================== | |
| 270 *90.3* Upgrading | |
| 271 | |
| 272 If you are running one version of Vim and want to install another, here is | |
| 273 what to do. | |
| 274 | |
| 275 | |
| 276 UNIX | |
| 277 | |
| 278 When you type "make install" the runtime files will be copied to a directory | |
| 279 which is specific for this version. Thus they will not overwrite a previous | |
| 280 version. This makes it possible to use two or more versions next to | |
| 281 each other. | |
| 282 The executable "vim" will overwrite an older version. If you don't care | |
| 283 about keeping the old version, running "make install" will work fine. You can | |
| 284 delete the old runtime files manually. Just delete the directory with the | |
| 285 version number in it and all files below it. Example: > | |
| 286 | |
| 19116 | 287 rm -rf /usr/local/share/vim/vim74 |
| 7 | 288 |
| 289 There are normally no changed files below this directory. If you did change | |
| 290 the "filetype.vim" file, for example, you better merge the changes into the | |
| 291 new version before deleting it. | |
| 292 | |
| 293 If you are careful and want to try out the new version for a while before | |
| 294 switching to it, install the new version under another name. You need to | |
| 295 specify a configure argument. For example: > | |
| 296 | |
| 19116 | 297 ./configure --with-vim-name=vim8 |
| 7 | 298 |
| 299 Before running "make install", you could use "make -n install" to check that | |
| 300 no valuable existing files are overwritten. | |
| 301 When you finally decide to switch to the new version, all you need to do is | |
| 302 to rename the binary to "vim". For example: > | |
| 303 | |
| 19116 | 304 mv /usr/local/bin/vim8 /usr/local/bin/vim |
| 7 | 305 |
| 306 | |
| 307 MS-WINDOWS | |
| 308 | |
| 309 Upgrading is mostly equal to installing a new version. Just unpack the files | |
| 310 in the same place as the previous version. A new directory will be created, | |
| 19116 | 311 e.g., "vim82", for the files of the new version. Your runtime files, vimrc |
| 7 | 312 file, viminfo, etc. will be left alone. |
| 313 If you want to run the new version next to the old one, you will have to do | |
| 314 some handwork. Don't run the install program, it will overwrite a few files | |
| 315 of the old version. Execute the new binaries by specifying the full path. | |
| 316 The program should be able to automatically find the runtime files for the | |
| 317 right version. However, this won't work if you set the $VIMRUNTIME variable | |
| 318 somewhere. | |
| 319 If you are satisfied with the upgrade, you can delete the files of the | |
| 320 previous version. See |90.5|. | |
| 321 | |
| 322 ============================================================================== | |
| 323 *90.4* Common installation issues | |
| 324 | |
| 325 This section describes some of the common problems that occur when installing | |
| 326 Vim and suggests some solutions. It also contains answers to many | |
| 327 installation questions. | |
| 328 | |
| 329 | |
| 330 Q: I Do Not Have Root Privileges. How Do I Install Vim? (Unix) | |
| 331 | |
| 332 Use the following configuration command to install Vim in a directory called | |
| 333 $HOME/vim: > | |
| 334 | |
| 335 ./configure --prefix=$HOME | |
| 336 | |
| 337 This gives you a personal copy of Vim. You need to put $HOME/bin in your | |
| 338 path to execute the editor. Also see |install-home|. | |
| 339 | |
| 340 | |
| 341 Q: The Colors Are Not Right on My Screen. (Unix) | |
| 342 | |
| 343 Check your terminal settings by using the following command in a shell: > | |
| 344 | |
| 345 echo $TERM | |
| 346 | |
| 347 If the terminal type listed is not correct, fix it. For more hints, see | |
| 348 |06.2|. Another solution is to always use the GUI version of Vim, called | |
| 349 gvim. This avoids the need for a correct terminal setup. | |
| 350 | |
| 351 | |
| 352 Q: My Backspace And Delete Keys Don't Work Right | |
| 353 | |
| 354 The definition of what key sends what code is very unclear for backspace <BS> | |
| 355 and Delete <Del> keys. First of all, check your $TERM setting. If there is | |
| 356 nothing wrong with it, try this: > | |
| 357 | |
| 358 :set t_kb=^V<BS> | |
| 359 :set t_kD=^V<Del> | |
| 360 | |
| 361 In the first line you need to press CTRL-V and then hit the backspace key. | |
| 362 In the second line you need to press CTRL-V and then hit the Delete key. | |
| 363 You can put these lines in your vimrc file, see |05.1|. A disadvantage is | |
| 364 that it won't work when you use another terminal some day. Look here for | |
| 365 alternate solutions: |:fixdel|. | |
| 366 | |
| 367 | |
| 368 Q: I Am Using RedHat Linux. Can I Use the Vim That Comes with the System? | |
| 369 | |
| 370 By default RedHat installs a minimal version of Vim. Check your RPM packages | |
| 371 for something named "Vim-enhanced-version.rpm" and install that. | |
| 372 | |
| 373 | |
| 374 Q: How Do I Turn Syntax Coloring On? How do I make plugins work? | |
| 375 | |
| 376 Use the example vimrc script. You can find an explanation on how to use it | |
| 377 here: |not-compatible|. | |
| 378 | |
| 379 See chapter 6 for information about syntax highlighting: |usr_06.txt|. | |
| 380 | |
| 381 | |
| 382 Q: What Is a Good vimrc File to Use? | |
| 383 | |
| 384 See the www.vim.org Web site for several good examples. | |
| 385 | |
| 386 | |
| 387 Q: Where Do I Find a Good Vim Plugin? | |
| 388 | |
| 389 See the Vim-online site: http://vim.sf.net. Many users have uploaded useful | |
| 390 Vim scripts and plugins there. | |
| 391 | |
| 392 | |
| 393 Q: Where Do I Find More Tips? | |
| 394 | |
| 395 See the Vim-online site: http://vim.sf.net. There is an archive with hints | |
| 396 from Vim users. You might also want to search in the |maillist-archive|. | |
| 397 | |
| 398 ============================================================================== | |
| 399 *90.5* Uninstalling Vim | |
| 400 | |
| 401 In the unlikely event you want to uninstall Vim completely, this is how you do | |
| 402 it. | |
| 403 | |
| 404 | |
| 405 UNIX | |
| 406 | |
| 407 When you installed Vim as a package, check your package manager to find out | |
| 408 how to remove the package again. | |
| 409 If you installed Vim from sources you can use this command: > | |
| 410 | |
| 411 make uninstall | |
| 412 | |
| 413 However, if you have deleted the original files or you used an archive that | |
| 414 someone supplied, you can't do this. Do delete the files manually, here is an | |
| 415 example for when "/usr/local" was used as the root: > | |
| 416 | |
| 19116 | 417 rm -rf /usr/local/share/vim/vim82 |
| 7 | 418 rm /usr/local/bin/eview |
| 419 rm /usr/local/bin/evim | |
| 420 rm /usr/local/bin/ex | |
| 421 rm /usr/local/bin/gview | |
| 422 rm /usr/local/bin/gvim | |
| 423 rm /usr/local/bin/gvim | |
| 424 rm /usr/local/bin/gvimdiff | |
| 425 rm /usr/local/bin/rgview | |
| 426 rm /usr/local/bin/rgvim | |
| 427 rm /usr/local/bin/rview | |
| 428 rm /usr/local/bin/rvim | |
| 429 rm /usr/local/bin/rvim | |
| 430 rm /usr/local/bin/view | |
| 431 rm /usr/local/bin/vim | |
| 432 rm /usr/local/bin/vimdiff | |
| 433 rm /usr/local/bin/vimtutor | |
| 434 rm /usr/local/bin/xxd | |
| 435 rm /usr/local/man/man1/eview.1 | |

| 455 the "uninstall-gui" program located in the same directory as the other Vim | |
| 19116 | 456 programs, e.g. "c:\vim\vim82". You can also launch it from the Start menu if |
