DESCRIPTION
This plugin provides commands and functions to set up regions in the current
buffer that either use a syntax different from the buffer's 'filetype', or
completely ignore the syntax.

SEE ALSO
- If you also want different buffer options (like indent settings, etc.) for
  each syntax region, the OnSyntaxChange.vim plugin (vimscript #4085) allows
  you to dynamically change the buffer options as you move through the buffer.

RELATED WORKS
- If the highlighting doesn't work properly, you could alternatively edit the
  range(s) in a separate scratch buffer. Plugins like NrrwRgn (vimscript #3075)
  provide commands to set these up, with automatic syncing back to the
  original buffer.

SOURCE
The code to include a different syntax in a region is based on
    http://vim.wikia.com/wiki/Different_syntax_highlighting_within_regions_of_a_file

USAGE
For quick, ad-hoc manipulation of the syntax withing a range of lines, the
following commands are provided:

:[range]SyntaxIgnore    Ignore the buffer's filetype syntax for the current
                        line / lines in [range]. (Top-level keywords will
                        still be highlighted.)
                        This can be a useful fix when some text fragments
                        confuse the syntax highlighting. (For example, when
                        buffer syntax set to an inlined here-document is
                        negatively affected by the foreign code surrounding
                        the here-document.)

:[range]SyntaxInclude {filetype}
                        Use the {filetype} syntax for the current line / lines
                        in [range].

                        Line numbers in [range] are fixed; i.e. they do not
                        adapt to inserted / deleted lines. But when in a
                        range, the last line ($) is interpreted as "end of
                        file".

For finer control and use in custom mappings or syntax tweaks, the following
functions can be used. You'll find the details directly in the
.vim/autoload/SyntaxRange.vim implementation file.

SyntaxRange#Include( {startPattern}, {endPattern}, {filetype} [, {matchGroup} [, {contains}]] )
                        Use the {filetype} syntax for the region defined by
                        {startPattern} and {endPattern}. Optionally highlight
                        {startPattern} and {endPattern} itself with
                        {matchGroup}, and additionally allow {contains} groups
                        inside the region.
SyntaxRange#IncludeEx( {regionDefinition}, {filetype} [, {contains}] )
                        Use the {filetype} syntax for the region defined by
                        {regionDefinition}. Additionally allow {contains}
                        groups inside the region.

EXAMPLE
To highlight the text between the markers with C syntax:
    @begin=c@
    int i = 42;
    @end=c@

To do this statically, with fixed line numbers, for the first occurrence in
the file:
    :1;/@begin=c@/,/@end=c@/SyntaxInclude c

The dynamic version will apply to all occurrences, handles changes in the line
numbers, and also can make the markers themselves fade into the background:
    :call SyntaxRange#Include('@begin=c@', '@end=c@', 'c', 'NonText')

To highlight inline patches inside emails:
    :call SyntaxRange#IncludeEx('start="^changeset\|^Index: \|^diff \|^--- .*\%( ----\)\@<!$" skip="^[-+@       ]" end="^$"', 'diff')
To install this automatically for the "mail" filetype, put above line into a
script in ~/.vim/after/syntax/mail/SyntaxInclude.vim

INSTALLATION
The code is hosted in a Git repo at
    https://github.com/inkarkat/vim-SyntaxRange
You can use your favorite plugin manager, or "git clone" into a directory used
for Vim packages. Releases are on the "stable" branch, the latest unstable
development snapshot on "master".

This script is also packaged as a vimball. If you have the "gunzip"
decompressor in your PATH, simply edit the *.vmb.gz package in Vim; otherwise,
decompress the archive first, e.g. using WinZip. Inside Vim, install by
sourcing the vimball or via the :UseVimball command.
    vim SyntaxRange*.vmb.gz
    :so %
To uninstall, use the :RmVimball command.

DEPENDENCIES
- Requires Vim 7.0 or higher.
- Requires the ingo-library.vim plugin (vimscript #4433), version 1.022 or
  higher.

INTEGRATION
To automatically include a syntax in a certain {filetype}, you can put the
command into a script in
    ~/.vim/after/syntax/{filetype}/SyntaxInclude.vim
If you want to include a syntax in several (or even all) syntaxes, you can put
this into your vimrc:
    :autocmd Syntax * call SyntaxRange#Include(...)

If you have a filetype1 syntax that includes filetype2 and vice versa, you
will run into E169: Command too recursive. This can be solved by inclusion
guards around each invocation. In ~/.vim/after/syntax/filetype1.vim:
    let b:loaded_filetype1_syntax_includes = 1
    if !exists('b:loaded_filetype2_syntax_includes')
        call SyntaxRange#Include('...', '...', 'filetype2')
    endif
    ...
    unlet b:loaded_filetype1_syntax_includes
And the inverse in ~/.vim/after/syntax/filetype2.vim:
    let b:loaded_filetype2_syntax_includes = 1
    if !exists('b:loaded_filetype1_syntax_includes')
        call SyntaxRange#Include('...', '...', 'filetype1')
    endif
    ...
    unlet b:loaded_filetype2_syntax_includes

package script version date Vim version user release notes
SyntaxRange-1.04.vmb.gz 1.04 2024-11-13 7.0 Ingo Karkat - Allow setting additional contains groups via an optional argument to SyntaxRange#Include[Ex](). Thanks to Sergey Vlasov for sending a patch.
- Rename the re-inclusion guard from b:SyntaxInclude_IncludedFiletypes (List) to b:SyntaxInclude_Included (Dict). Handle buffer reload via :edit by making it dependent on b:changedtick as well.
SyntaxRange-1.03.vmb.gz 1.03 2017-07-03 7.0 Ingo Karkat - SyntaxRange#Include(): Escape double quotes in a:startPattern and a:endPattern; i.e. handle the patterns transparently. Found in tmsanrinsha's fork.
- ENH: Avoid to re-include same syntax file if multiple ranges are specified with :SyntaxInclude / if SyntaxRange#Include[Ex]() is invoked multiple times per buffer. Found in tmsanrinsha's fork.
SyntaxRange-1.02.vmb.gz 1.02 2015-04-23 7.0 Ingo Karkat - Set main_syntax to the buffer's syntax during :syntax include of the subordinate syntax script. Some scripts may make special arrangements when included. Suggested by OOO.
- Handle :.SyntaxInclude and :.SyntaxIgnore on folded lines correctly. Use ingo#range#NetStart/End().
- Add dependency to ingo-library (vimscript #4433). *** You need to separately install ingo-library (vimscript #4433) version 1.022 (or higher)! ***
SyntaxRange-1.01.vmb.gz 1.01 2013-11-21 7.0 Ingo Karkat Avoid "E108: No such variable: b:current_syntax" when the (misbehaving) included syntax doesn't set it. Reported by o2genum at http://stackoverflow.com/a/16162412/813602.
SyntaxRange.vba.gz 1.00 2012-08-13 7.0 Ingo Karkat Initial upload
