*usr_22.txt* For Vim version 7.0. Last change: 2006 Apr 24 VIM USER MANUAL - by Bram Moolenaar Finding the file to edit Files can be found everywhere. So how do you find them? Vim offers various ways to browse the directory tree. There are commands to jump to a file that is mentioned in another. And Vim remembers which files have been edited before. |22.1| The file explorer |22.2| The current directory |22.3| Finding a file |22.4| The buffer list Next chapter: |usr_23.txt| Editing other files Previous chapter: |usr_21.txt| Go away and come back Table of contents: |usr_toc.txt| ============================================================================== *22.1* The file explorer Vim has a plugin that makes it possible to edit a directory. Try this: > :edit . Through the magic of autocommands and Vim scripts, the window will be filled with the contents of the directory. It looks like this: " Press ? for keyboard shortcuts ~ " Sorted by name (.bak,~,.o,.h,.info,.swp,.obj,.orig,.rej at end of list) ~ "= /home/mool/vim/vim6/runtime/doc/ ~ ../ ~ check/ ~ Makefile ~ autocmd.txt ~ change.txt ~ eval.txt~ ~ filetype.txt~ ~ help.txt.info ~ You can see these items: 1. A comment about using ? to get help for the functionality of the file explorer. 2. The second line mentions how the items in the directory are listed. They can be sorted in several ways. 3. The third line is the name of the current directory. 4. The "../" directory item. This is the parent directory. 5. The directory names. 6. The ordinary file names. As mentioned in the second line, some are not here but "at the end of the list". 7. The less ordinary file names. You are expected to use these less often, therefore they have been moved to the end. If you have syntax highlighting enabled, the different parts are highlighted to make it easier to spot them. You can use Normal mode Vim commands to move around in the text. For example, move to a file and press . Now you are editing that file. To go back to the explorer use ":edit ." again. CTRL-O also works. Try using while the cursor is on a directory name. The result is that the explorer moves into that directory and displays the items found there. Pressing on the first directory "../" moves you one level higher. Pressing "-" does the same thing, without the need to move to the "../" item first. You can press ? to get short help on the things you can do in the explorer. This is what you get: " : open file or directory ~ " o : open new window for file/directory ~ " O : open file in previously visited window ~ " p : preview the file ~ " i : toggle size/date listing ~ " s : select sort field r : reverse sort ~ " - : go up one level c : cd to this dir ~ " R : rename file D : delete file ~ " :help file-explorer for detailed help ~ The first few commands are for selecting a file to display. Depending on what command you use, the file appears somewhere: Uses the current window. o Opens a new window. O Uses the previously visited window. p Uses the preview window, and moves the cursor back into the explorer window. |preview-window| The following commands are used to display other information: i Display the size and date for the file. Using i again will hide the information. s Use the field the cursor is in to sort on. First display the size and date with i. Then Move the cursor to the size of any file and press s. The files will now be sorted on size. Press s while the cursor is on a date and the items will be sorted on date. r reverse the sorting order (either size or date) There are a few extra commands: c Change the current directory to the displayed directory. You can then type an ":edit" command for one of the files without prepending the path. R Rename the file under the cursor. You will be prompted for the new name. D Delete the file under the cursor. You will get a prompt to confirm this. ============================================================================== *22.2* The current directory Just like the shell, Vim has the concept of a current directory. Suppose you are in your home directory and want to edit several files in a directory "VeryLongFileName". You could do: > :edit VeryLongFileName/file1.txt :edit VeryLongFileName/file2.txt :edit VeryLongFileName/file3.txt To avoid much of the typing, do this: > :cd VeryLongFileName :edit file1.txt :edit file2.txt :edit file3.txt The ":cd" command changes the current directory. You can see what the current directory is with the ":pwd" command: > :pwd /home/Bram/VeryLongFileName Vim remembers the last directory that you used. Use "cd -" to go back to it. Example: > :pwd /home/Bram/VeryLongFileName :cd /etc :pwd /etc :cd - :pwd /home/Bram/VeryLongFileName :cd - :pwd /etc WINDOW LOCAL DIRECTORY When you split a window, both windows use the same current directory. When you want to edit a number of files somewhere else in the new window, you can make it use a different directory, without changing the current directory in the other window. This is called a local directory. > :pwd /home/Bram/VeryLongFileName :split :lcd /etc :pwd /etc CTRL-W w :pwd /home/Bram/VeryLongFileName So long as no ":lcd" command has been used, all windows share the same current directory. Doing a ":cd" command in one window will also change the current directory of the other window. For a window where ":lcd" has been used a different current directory is remembered. Using ":cd" or ":lcd" in other windows will not change it. When using a ":cd" command in a window that uses a different current directory, it will go back to using the shared directory. ============================================================================== *22.3* Finding a file You are editing a C program that contains this line: #include "inits.h" ~ You want to see what is in that "inits.h" file. Move the cursor on the name of the file and type: > gf Vim will find the file and edit it. What if the file is not in the current directory? Vim will use the 'path' option to find the file. This option is a list of directory names where to look for your file. Suppose you have your include files located in "c:/prog/include". This command will add it to the 'path' option: > :set path+=c:/prog/include This directory is an absolute path. No matter where you are, it will be the same place. What if you have located files in a subdirectory, below where the file is? Then you can specify a relative path name. This starts with a dot: > :set path+=./proto This tells Vim to look in the directory "proto", below the directory where the file in which you use "gf" is. Thus using "gf" on "inits.h" will make Vim look for "proto/inits.h", starting in the directory of the file. Without the "./", thus "proto", Vim would look in the "proto" directory below the current directory. And the current directory might not be where the file that you are editing is located. The 'path' option allows specifying the directories where to search for files in many more ways. See the help on the 'path' option. The 'isfname' option is used to decide which characters are included in the file name, and which ones are not (e.g., the " character in the example above). When you know the file name, but it's not to be found in the file, you can type it: > :find inits.h Vim will then use the 'path' option to try and locate the file. This is the same as the ":edit" command, except for the use of 'path'. To open the found file in a new window use CTRL-W f instead of "gf", or use ":sfind" instead of ":find". A nice way to directly start Vim to edit a file somewhere in the 'path': > vim "+find stdio.h" This finds the file "stdio.h" in your value of 'path'. The quotes are necessary to have one argument |-+c|. ============================================================================== *22.4* The buffer list The Vim editor uses the term buffer to describe a file being edited. Actually, a buffer is a copy of the file that you edit. When you finish changing the buffer, you write the contents of the buffer to the file. Buffers not only contain file contents, but also all the marks, settings, and other stuff that goes with it. HIDDEN BUFFERS Suppose you are editing the file one.txt and need to edit the file two.txt. You could simply use ":edit two.txt", but since you made changes to one.txt that won't work. You also don't want to write one.txt yet. Vim has a solution for you: > :hide edit two.txt The buffer "one.txt" disappears from the screen, but Vim still knows that you are editing this buffer, so it keeps the modified text. This is called a hidden buffer: The buffer contains text, but you can't see it. The ":hide" command argument is another command. It makes that command behave like the 'hidden' option was set. You could also set this option yourself. The effect is that when any buffer is abandoned, it becomes hidden. Be careful! When you have hidden buffers with changes, don't exit Vim without making sure you have saved all the buffers. INACTIVE BUFFERS When a buffer has been used once, Vim remembers some information about it. When it is not displayed in a window and it is not hidden, it is still in the buffer list. This is called an inactive buffer. Overview: Active Appears in a window, text loaded. Hidden Not in a window, text loaded. Inactive Not in a window, no text loaded. The inactive buffers are remembered, because Vim keeps information about them, like marks. And remembering the file name is useful too, so that you can see which files you have edited. And edit them again. LISTING BUFFERS View the buffer list with this command: > :buffers A command which does the same, is not so obvious to list buffers, but is much shorter to type: > :ls The output could look like this: 1 #h "help.txt" line 62 ~ 2 %a+ "usr_21.txt" line 1 ~ 3 "usr_toc.txt" line 1 ~ The first column contains the buffer number. You can use this to edit the buffer without having to type the name, see below. After the buffer number come the flags. Then the name of the file and the line number where the cursor was the last time. The flags that can appear are these (from left to right): u Buffer is unlisted |unlisted-buffer|. % Current buffer. # Alternate buffer. a Buffer is loaded and displayed. h Buffer is loaded but hidden. = Buffer is read-only. - Buffer is not modifiable, the 'modifiable' option is off. + Buffer has been modified. EDITING A BUFFER You can edit a buffer by its number. That avoids having to type the file name: > :buffer 2 But the only way to know the number is by looking in the buffer list. You can use the name, or part of it, instead: > :buffer help Vim will find a best match for the name you type. If there is only one buffer that matches the name, it will be used. In this case "help.txt". To open a buffer in a new window: > :sbuffer 3 This works with a name as well. USING THE BUFFER LIST You can move around in the buffer list with these commands: :bnext go to next buffer :bprevious go to previous buffer :bfirst go to the first buffer :blast go to the last buffer To remove a buffer from the list, use this command: > :bdelete 3 Again, this also works with a name. If you delete a buffer that was active (visible in a window), that window will be closed. If you delete the current buffer, the current window will be closed. If it was the last window, Vim will find another buffer to edit. You can't be editing nothing! Note: Even after removing the buffer with ":bdelete" Vim still remembers it. It's actually made "unlisted", it no longer appears in the list from ":buffers". The ":buffers!" command will list unlisted buffers (yes, Vim can do the impossible). To really make Vim forget about a buffer, use ":bwipe". Also see the 'buflisted' option. ============================================================================== Next chapter: |usr_23.txt| Editing other files Copyright: see |manual-copyright| vim:tw=78:ts=8:ft=help:norl:
