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 keymap 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.
:ta[g] tag
Jumps to tag (tags file: TAGPATH environment variable or ./tags).
:tn[ext]
Jumps to the next matching tag.
:tp[rev]
Jumps to the previous matching tag.
:po[p]
Pops tag stack.
:b[uffer] [buf]
Switch to buffer buf (buffer number or alias); lists buffers
if buf is missing.
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: switches to the English and alternate keymap.
- ze and zf in normal mode: switches to the English and alternate keymap.
- gu, gU, and g~ in normal mode: switches character case.
- ^l in normal mode: updates terminal dimensions (after resizing it).
- ^] and ^t in normal mode: jumps to tag and pops tag stack.
- gf in normal mode: edits the file whose address is under the cursor.
- gl in normal mode: like gf, but it reads line and column numbers too.
- ^ws, ^wo, ^wc, ^wj, ^wk, ^wx in normal mode: manages windows.
- ^wgf, ^wgl, ^w^] in normal mode: executes gf, gl, ^] in a new window.
- qX in normal mode: see q-commands section (X can be any letter).
Other noteworthy differences with vi(1):
- Neatvi assumes POSIX extended regular expressions (ERE) in search
patterns, conf.h variables, and even tags files.
- If paths start with =, they are assumed to be relative to the
directory of the current file.
- Neatvi highlights files whose names ends with ls as directory
listings; the gl command can be used to edit its files.
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
Q-COMMANDS
----------
For qX command in normal mode, Neatvi executes ECMD (defined in conf.h)
with the following parameters:
- X (the key following q)
- current file
- current line number
- current line offset
ECMD must print a line of ex commands and Neatvi executes this line.
Q-commands can be used to add interesting features to Neatvi, such as
language-dependent IDE features, for instance by connecting to an LSP
(language server protocol) server. As an example, the following
script shows how to use gopls to implement goto defintion and find
references for Go.
# Compile.
if test "$1" = "c"; then
go build >.make.ls 2>&1
echo ":e +1 .make.ls | :e"
fi
# Goto definition; uses gopls (not very efficient without using LSP).
if test "$1" = "d"; then
loc=`gopls definition $2:$3:$4`
if test -n "$loc"; then
echo $loc | sed -E 's/^([^:]+):([^:]+):([^:]+).*$/:e +\2 \1/'
fi
fi
# Find references. Use gl command on each line.
if test "$1" = "f"; then
gopls references $2:$3:$4 >$OUT/.out.ls
echo ":e +1 $OUT/.out.ls | :e"
fi
