It uses a -minimal interface (\di: you can think of it as *D*raw*I*t or *D*rawIt -*I*nitialize) to start it and (\ds: *D*rawIt *S*top) to stop it. Instead of -using "\" you may specify your own preference for a map leader (see -|mapleader|). - -With a trailing 'S', :DIstart will begin in single-bar mode (see |drawit-sngl|). -With a trailing 'D', :DIstart will begin in double-bar mode (see |drawit-dbl|). -Similarly, :DIsngl and :DIdbl will start DrawIt as well as begin in -single-bar or double-bar mode, respectively. - -A message, "[DrawIt]", will appear on the message line. - - -STOPPING *drawit-stop* {{{2 -\ds -:DIstop -:DrawIt! - -When you are done with DrawIt, use \ds to stop DrawIt mode.

When your |'encoding'| is utf-8 or utf-16, -DrawIt supports drawing with special box characters (single-bar, double_bar). -These commands are also used to switch to normal, single-bar, or double-bar -modes. - - -USER MAP PROTECTION *drawit-protect* {{{2 - -Starting DrawIt causes it to set up a number of maps which facilitate drawing. -DrawIt accommodates users with conflicting maps by saving both maps and user -options and before setting them to what DrawIt needs. When you stop DrawIt -(|drawit-stop|), DrawIt will restore the user's maps and options as they were -before DrawIt was started. - - -OPTIONS *drawit-options* {{{2 - - *g:drawit_insertmode* -g:drawit_insertmode : if this variable exists and is 1 then maps are - made which make cursor-control drawing available - while in insert mode, too. Otherwise, DrawIt's - maps only affect normal mode. - -DRAWING *drawit-drawing* {{{2 - -After DrawIt is started, use the number pad or arrow keys to move the cursor -about. As the cursor moves, DrawIt will then leave appropriate "line" -characters behind as you move horizontally, vertically, or diagonally, and -will transparently enlarge your file to accommodate your drawing as needed. -The trail will consist of -, |, \, / characters (depending on which direction -and SetDrawIt() changes), and + and X characters where line crossings occur. -You may use h-j-k-l to move about your display and generally use editing -commands as you wish even while in DrawIt mode. - -Another tool that may be used to convert Ascii-art into nice pictures is -available at https://github.com/christiangoltz/shaape . - - -CHANGING DRAWING CHARACTERS *drawit-setdrawit* {{{2 - -The SetDrawIt() function is available for those who wish to change the -characters that DrawIt uses. > - - ex. :call SetDrawIt('*','*','*','*','*','*','*') - ex. :call SetDrawIt('-','|','-','\','/','/','*') -< -The first example shows how to change all the DrawIt drawing characters to -asterisks, and the second shows how to give crossing priority to - and /. -The default setting is equivalent to: > - - :call SetDrawIt('|','-','+','\','/','X','*') -< -where SetDrawit()'s arguments refer, in order, to the > - - vertical drawing character - horizontal drawing character - horizontal/vertical crossing drawing character - down right drawing character - down left drawing character - diagonal crossing drawing character - ellipse boundary drawing character -< - -TIP *drawit-tip* - -I have found that sometimes one or more of the <home>, <end>, <pageup>, -and <pagedown> keys give unique sequences but are not interpreted -properly by Vim. This problem impacts DrawIt as it uses those four -keys to signify diagonal moves/drawing. One solution I use is to -put into my <.vimrc> file mapings like: - - map ^V... <home> - -where the ellipsis (...) is the actual character sequence produced by -hitting the key. The way to generate such maps is to type "map ", -followed by three control-v presses, press the associated key, then -a space followed by the proper interpretation sequence (ie. <home>). - - -MOVING *drawit-move* *drawit-moving* {{{2 - -DrawIt supports shifting the arrow keys to cause motion of the cursor. The -motion of the cursor will not modify what's below the cursor. The cursor -will move and lines and/or spaces will be inserted to support the move as -required. Your terminal may not support shifted arrow keys, however, or Vim -may not catch them as such. For example, on the machine I use, shift-up -(<s-up>) produced <Esc>[161q, but vim didn't know that sequence was a <s-up>. -I merely made a nmap: - - nmap <Esc>[161q <s-up> - -and vim thereafter recognized the <s-up> command. - - -ERASING *drawit-erase* {{{2 -<space> - -The <space> key will toggle DrawIt's erase mode/DrawIt mode. When in [DrawIt -erase] mode, a message "[DrawIt erase]" will appear and the number pad will -now cause spaces to be drawn instead of the usual drawing characters. The -drawing behavior will be restored when the <space> key toggles DrawIt back -to regular DrawIt mode. - - -EXAMPLES *drawit-example* {{{2 - -Needless to say, the square spirals which follow were done with DrawIt and -a bit of block editing with Vim: > - - +------------ -----------+ +------------ -----------+ +------------ - |+----------+ +---------+| |+----------+ +---------+| |+----------+ - ||+--------+| |+-------+|| ||+--------+| |+-------+|| ||+--------+| - |||-------+|| ||+------||| |||-------+|| ||+------||| |||-------+|| - ||+-------+|| ||+------+|| ||+-------+|| ||+------+|| ||+-------+|| - |+---------+| |+--------+| |+---------+| |+--------+| |+---------+| - +-----------+ +----------+ +-----------+ +----------+ +-----------+ - -VISUAL BLOCK MODE FOR ARROWS LINES BOXES AND ELLIPSES *drawit-visblock* {{{2 - -\a : draw arrow from corners of visual-block selected region *drawit-a* -\b : draw box on visual-block selected region *drawit-b* -\c : the canvas routine (will query user, see above) *drawit-c* -\e : draw an ellipse on visual-block selected region *drawit-e* -\f : flood figure with a character (you will be prompted) *drawit-f* -\l : draw line from corners of visual-block selected region *drawit-l* -\s : spacer: appends spaces up to the textwidth (default: 78) *drawit-s* - -The DrawIt package has been merged with Sylvain Viart's drawing package (by -permission) which provides DrawIt with visual-block selection of -starting/ending point drawing of arrows (\a), lines (\l), and boxes (\b). -Additionally I wrote an ellipse drawing function using visual block -specification (|drawit-e|). - -One may create a block of spaces for these maps to operate in; the "canvas" -routine (\c) will help create such blocks. First, the s:Canvas() routine will -query the user for the number of lines s/he wishes to have, and will then fill -those lines with spaces out to the |'textwidth'| if user has specified it; -otherwise, the display width will be used. - -Although most of the maps use visual-block selection, that isn't true of the -\f map. Instead, it assume that you have already drawn some closed figure -and want to fill it with some character. - -The Sylvain Viart functions and the ellipse drawing function depend -upon using visual block mode. As a typical use: > - - Example: * \h - DrawIt asks: how many lines under the cursor? 10 - DrawIt then appends 10 lines filled with blanks - out to textwidth (if defined) or 78 columns. - * ctrl-v (move) \b - DrawIt then draws a box - * ctrl-v (move) \e - DrawIt then draws an ellipse -< -Select the first endpoint with ctrl-v and then move to the other endpoint. -One may then select \a for arrows, \b for boxes, \e for ellipses, or \l for -lines. The internal s:AutoCanvas() will convert tabs to spaces and will -extend with spaces as needed to support the visual block.
