NEATVI ====== Neatvi is a vi/ex editor. It can edit bidirectional UTF-8 text. CONFIGURATION ------------- Edit conf.h to adjust syntax highlighting rules and text direction patterns. To define a new keymap, create a new array in kmap.h, like kmap_fa, and add it to kmaps array in the same header (the first entry of the new array specifies its name). The current keymap may be changed with :cm ex command. When in input mode, ^e activates the English kaymap and ^f switches to the alternate keymap (the last keymap specified with :cm). Sadly, VTE-based terminals such as GNOME's implement a backward-incompatible extension of virtual terminal escape codes to render bidirectional text by default. When using these terminal, the value of LNPREF macro in conf.h needs to be edited. COMMANDS -------- Commands not available in ex(1): :cm[ap][!] [kmap] Without kmap, prints the current keymap name. When kmap is specified, sets the alternate keymap to kmap and, unless ! is given, switches to this keymap. :ft [filetype] Without filetype, prints the current file type. When filetype is specified, sets the file type of the current ex buffer. New key mappings: ^a in normal mode: searches for the word under the cursor. ^p in insert mode: inserts the contents of the default yank buffer. zL, zl, zr, and zR in normal mode: change the value of td option. ^e and ^f in insert mode: switch to the English and alternate keymap. ze and zf in normal mode: switch to the English and alternate keymap. gu, gU, and g~ in normal mode: switch character case. ^l in normal mode: updates terminal dimensions (after resizing it). OPTIONS ------- To improve neatvi's performance, shaping, character reordering, and syntax highlighting can be disabled by defining the EXINIT environment variable as "set noshape | set noorder | set nohl | set td=+2". Options supported in neatvi: td, textdirection Current direction context. The following values are meaningful: * +2: always left-to-right. * +1: follow conf.h's dircontexts[]; left-to-right for others. * -1: follow conf.h's dircontexts[]; right-to-left for others. * -2: always right-to-left. shape If set (default), performs Arabic/Farsi letter shaping. order If set, reorder characters based on the rules defined in conf.h. hl, highlight If set (default), text will be highlighted based on syntax highlighting rules in conf.h. hll, highlightline If set, highlight current line. lim, linelimit Lines longer than this value are not reordered or highlighted. ai, autoindent As in vi(1). aw, autowrite As in vi(1). ic, ignorecase As in vi(1). MARKS AND BUFFERS ----------------- Special marks: * the position of the previous change [ the first line of the previous change ] the last line of the previous change Special yank buffers: / the previous search keyword : the previous ex command
