detection, because it's common to start with a line that defines a mapping
that ends in a <CR>, which will confuse the automaton.
*line-continuation*
Long lines in a ":source"d Ex command script file can be split by inserting
a line continuation symbol "\" (backslash) at the start of the next line.
There can be white space before the backslash, which is ignored.
Example: the lines >
:set comments=sr:/*,mb:*,el:*/,
\://,
\b:#,
\:%,
\n:>,
\fb:-
are interpreted as if they were given in one line: >
:set comments=sr:/*,mb:*,el:*/,://,b:#,:%,n:>,fb:-
All leading whitespace characters in the line before a backslash are ignored.
Note however that trailing whitespace in the line before it cannot be
inserted freely; it depends on the position where a command is split up
whether additional whitespace is allowed or not.
When a space is required it's best to put it right after the backslash. A
space at the end of a line is hard to see and may be accidentally deleted. >
:syn match Comment
\ "very long regexp"
\ keepend
There is a problem with the ":append" and ":insert" commands: >
:1append
\asdf
.
The backslash is seen as a line-continuation symbol, thus this results in the
command: >
:1appendasdf
.
To avoid this, add the 'C' flag to the 'cpoptions' option: >
:set cpo+=C
:1append
\asdf
.
:set cpo-=C
Note that when the commands are inside a function, you need to add the 'C'
flag when defining the function, it is not relevant when executing it. >
:set cpo+=C
:function Foo()
:1append
\asdf
.
:endfunction
:set cpo-=C
<
*line-continuation-comment*
To add a comment in between the lines start with `'"\ '`. Notice the space
after the backslash. Example: >
let array = [
"\ first entry comment
\ 'first',
"\ second entry comment
\ 'second',
\ ]
Rationale:
Most programs work with a trailing backslash to indicate line
continuation. Using this in Vim would cause incompatibility with Vi.
For example for this Vi mapping: >
:map xx asdf\
< Therefore the unusual leading backslash is used.
Starting a comment in a continuation line results in all following
continuation lines to be part of the comment. Since it was like this
for a long time, when making it possible to add a comment halfway a
sequence of continuation lines, it was not possible to use \", since
that was a valid continuation line. Using `'"\ '` comes closest, even
though it may look a bit weird. Requiring the space after the
backslash is to make it very unlikely this is a normal comment line.

Using Vim packages *packages*
A Vim "package" is a directory that contains |plugin|s. Compared to normal
plugins, a package can...
- be downloaded as an archive and unpacked in its own directory, so the files
are not mixed with files of other plugins.
- be a git, mercurial, etc. repository, thus easy to update.
- contain multiple plugins that depend on each other.
- contain plugins that are automatically loaded on startup ("start" packages,
located in "pack/*/start/*") and ones that are only loaded when needed with
|:packadd| ("opt" packages, located in "pack/*/opt/*").
*runtime-search-path*
Nvim searches for |:runtime| files in:
1. all paths in 'runtimepath'
2. all "pack/*/start/*" dirs
Note that the "pack/*/start/*" paths are not explicitly included in
'runtimepath', so they will not be reported by ":set rtp" or "echo &rtp".
Scripts can use |nvim_list_runtime_paths()| to list all used directories, and
|nvim_get_runtime_file()| to query for specific files or sub-folders within
the runtime path. Example: >
" List all runtime dirs and packages with Lua paths.
:echo nvim_get_runtime_file("lua/", v:true)
Using a package and loading automatically ~
Let's assume your Nvim files are in "~/.local/share/nvim/site" and you want to
add a package from a zip archive "/tmp/foopack.zip":
