+This directory contains files to automatically compute the indent for a
+type of file.
+
+If you want to add your own indent file for your personal use, read the docs
+at ":help indent-expression". Looking at the existing files should give you
+inspiration.
+
+If you make a new indent file which would be useful for others, please send it
+to the vim-dev mailing list <vim-dev@vim.org>. Include instructions for
+detecting the file type for this language, by file name extension or by
+checking a few lines in the file. And please stick to the rules below.
+
+If you have remarks about an existing file, send them to the maintainer of
+that file. Only when you get no response send a message to the vim-dev
+mailing list: <vim-dev@vim.org>.
+
+If you are the maintainer of an indent file and make improvements, e-mail the
+new version to the vim-dev mailing list: <vim-dev@vim.org>.
+
+
+Rules for making an indent file:
+
+You should use this check for "b:did_indent":
+
+ " Only load this indent file when no other was loaded yet.
+ if exists("b:did_indent")
+ finish
+ endif
+ let b:did_indent = 1
+
+Always use ":setlocal" to set 'indentexpr'. This avoids it being carried over
+to other buffers.
+
+To trigger the indenting after typing a word like "endif", add the word to the
+'indentkeys' option with "+=".
+
+You normally set 'indentexpr' to evaluate a function and then define that
+function. That function only needs to be defined once for as long as Vim is
+running. Add a test if the function exists and use ":finish", like this:
+ if exists("*GetMyIndent")
+ finish
+ endif
+
+The user may have several options set unlike you, try to write the file such
+that it works with any option settings. Also be aware of certain features not
+being compiled in.
+
+To test the indent file, see testdir/README.txt.

+" Awk indent script. It can handle multi-line statements and expressions.
+" It works up to the point where the distinction between correct/incorrect

+"
+" Bugs:
+" =====
+" - Some syntax errors may cause erratic indentation.
+" - Same for very unusual but syntacticly correct use of { }
+" - In some cases it's confused by the use of ( and { in strings constants
+" - This version likes the closing brace of a multiline pattern-action be on

+" 29-04-2002 Fixed problems in function headers and max line width

+" Vim indent file
+" Language: PHP
+" Author: John Wellesz <John.wellesz (AT) gmail (DOT) com>
+" URL: https://www.2072productions.com/vim/indent/php.vim
+" Home: https://github.com/2072/PHP-Indenting-for-VIm
+" Last Change: 2023 August 18th
+" Version: 1.75
+"
+"
+" Type :help php-indent for available options
+"
+" A fully commented version of this file is available on github
+"
+"
+" If you find a bug, please open a ticket on github.com
+" ( https://github.com/2072/PHP-Indenting-for-VIm/issues ) with an example of
+" code that breaks the algorithm.
+"
+
+" NOTE: This script must be used with PHP syntax ON and with the php syntax
+" script by Lutz Eymers (http://www.isp.de/data/php.vim ) or with the
+" script by Peter Hodge (https://www.vim.org/scripts/script.php?script_id=1571 )
+" the later is bunbdled by default with Vim 7.
+"
+"
+" In the case you have syntax errors in your script such as HereDoc end
+" identifiers not at col 1 you'll have to indent your file 2 times (This
+" script will automatically put HereDoc end identifiers at col 1 if
+" they are followed by a ';').
+"
+
+" NOTE: If you are editing files in Unix file format and that (by accident)
+" there are '\r' before new lines, this script won't be able to proceed
+" correctly and will make many mistakes because it won't be able to match
+" '\s*$' correctly.
+" So you have to remove those useless characters first with a command like:
+"
+" :%s /\r$//g
+"
+" or simply 'let' the option PHP_removeCRwhenUnix to 1 and the script will
+" silently remove them when VIM load this script (at each bufread).

+" Notes:
+" Indenting keywords are based on Oracle and Sybase Adaptive Server
+" Anywhere (ASA). Test indenting was done with ASA stored procedures and
+" functions and Oracle packages which contain stored procedures and
+" functions.
+" This has not been tested against Microsoft SQL Server or
+" Sybase Adaptive Server Enterprise (ASE) which use the Transact-SQL
+" syntax. That syntax does not have end tags for IF's, which makes
+" indenting more difficult.
+"
+" Known Issues:
+" The Oracle MERGE statement does not have an end tag associated with
+" it, this can leave the indent hanging to the right one too many.
+"
+" History:
+" 4.0 (Oct 2021)
+" Added b:undo_indent
+"
+" 3.0 (Dec 2012)
+" Added cpo check
+"
+" 2.0
+" Added the FOR keyword to SQLBlockStart to handle (Alec Tica):

+" |<-- I expect to have indentation here
+" end loop;
+"

+TESTING INDENT SCRIPTS
+
+We'll use FILETYPE for the filetype name here.
+
+
+FORMAT OF THE FILETYPE.IN FILE
+
+First of all, create a FILETYPE.in file. It should contain:
+
+- A modeline setting the 'filetype' and any other option values.
+ This must work like a comment for FILETYPE. E.g. for vim:
+ " vim: set ft=vim sw=4 :
+
+- At least one block of lines to indent, prefixed with START_INDENT and
+ followed by END_INDENT. These lines must also look like a comment for your
+ FILETYPE. You would normally leave out all indent, so that the effect of
+ the indent command results in adding indent. Example:
+
+ " START_INDENT
+ func Some()
+ let x = 1
+ endfunc
+ " END_INDENT
+
+ If you just want to test normal indenting with default options, you can make
+ this a large number of lines. Just add all kinds of language constructs,
+ nested statements, etc. with valid syntax.
+
+- Optionally, add lines with INDENT_EXE after START_INDENT, followed by a Vim
+ command. This will be executed before indenting the lines. Example:
+
+ " START_INDENT
+ " INDENT_EXE let g:vim_indent_cont = 6
+ let cmd =
+ \ 'some '
+ \ 'string'
+ " END_INDENT
+
+ Note that the command is not undone, you may need to reverse the effect for
+ the next block of lines.
+
+- Alternatively to indenting all the lines between START_INDENT and
+ END_INDENT, use an INDENT_AT line, which specifies a pattern to find the
+ line to indent. Example:
+
+ " START_INDENT
+ " INDENT_AT this-line
+ func Some()
+ let f = x " this-line
+ endfunc
+ " END_INDENT
+
+ Alternatively you can use INDENT_NEXT to indent the line below the matching
+ pattern. Keep in mind that quite often it will indent relative to the
+ matching line:
+
+ " START_INDENT
+ " INDENT_NEXT next-line
+ func Some()
+ " next-line
+ let f = x
+ endfunc
+ " END_INDENT
+
+ Or use INDENT_PREV to indent the line above the matching pattern:
+
+ " START_INDENT
+ " INDENT_PREV prev-line
+ func Some()
+ let f = x
+ " prev-line
+ endfunc
+ " END_INDENT
+
+It's best to keep the whole file valid for FILETYPE, so that syntax
+highlighting works normally, and any indenting that depends on the syntax
+highlighting also works.
+
+
+RUNNING THE TEST
+
+Before running the test, create a FILETYPE.ok file. You can leave it empty at
+first.
+
+Now run "make test" from the parent directory. After Vim has done the
+indenting you will see a FILETYPE.fail file. This contains the actual result
+of indenting, and it's different from the FILETYPE.ok file.
+
+Check the contents of the FILETYPE.fail file. If it is perfectly OK, then
+rename it to overwrite the FILETYPE.ok file. If you now run "make test" again,
+the test will pass and create a FILETYPE.out file, which is identical to the
+FILETYPE.ok file. The FILETYPE.fail file will be deleted.
+
+If you try to run "make test" again you will notice that nothing happens,
+because the FILETYPE.out file already exists. Delete it, or do "make clean",
+so that the text runs again. If you edit the FILETYPE.in file, so that it's
+newer than the FILETYPE.out file, the test will also run.

+" Please email me if you found something I can do. Comments, bug report and
+" feature request are welcome.
+
+" Last Update: {{{
+" 25th Sep 2002, by LH :
+" (*) better support for the option
+" (*) use some regex instead of several '||'.
+" Oct 9th, 2003, by JT:
+" (*) don't change indentation of lines starting with '%'
+" 2005/06/15, Moshe Kaminsky <kaminsky AT math.huji.ac.il>
+" (*) New variables:
+" g:tex_items, g:tex_itemize_env, g:tex_noindent_env
+" 2011/3/6, by Yichao Zhou <broken.zhou AT gmail.com>
+" (*) Don't change indentation of lines starting with '%'
+" I don't see any code with '%' and it doesn't work properly
+" so I add some code.
+" (*) New features: Add smartindent-like indent for "{}" and "[]".
+" (*) New variables: g:tex_indent_brace
+" 2011/9/25, by Yichao Zhou <broken.zhou AT gmail.com>
+" (*) Bug fix: smartindent-like indent for "[]"
+" (*) New features: Align with "&".
+" (*) New variable: g:tex_indent_and.
+" 2011/10/23 by Yichao Zhou <broken.zhou AT gmail.com>
+" (*) Bug fix: improve the smartindent-like indent for "{}" and
+" "[]".
+" 2012/02/27 by Yichao Zhou <broken.zhou AT gmail.com>
+" (*) Bug fix: support default folding marker.
+" (*) Indent with "&" is not very handy. Make it not enable by
+" default.
+" 2012/03/06 by Yichao Zhou <broken.zhou AT gmail.com>
+" (*) Modify "&" behavior and make it default again. Now "&"
+" won't align when there are more then one "&" in the previous
+" line.
+" (*) Add indent "\left(" and "\right)"
+" (*) Trust user when in "verbatim" and "lstlisting"
+" 2012/03/11 by Yichao Zhou <broken.zhou AT gmail.com>

+" (*) Fix problem about GetTeXIndent checker. Thank Albert Netymk
+" for reporting this.
+" 2014/06/23 by Yichao Zhou <broken.zhou AT gmail.com>
+" (*) Remove the feature g:tex_indent_and because it is buggy.
+" (*) If there is not any obvious indentation hints, we do not
+" alert our user's current indentation.
+" (*) g:tex_indent_brace now only works if the open brace is the
+" last character of that line.
+" 2014/08/03 by Yichao Zhou <broken.zhou AT gmail.com>
+" (*) Indent current line if last line has larger indentation
+" 2016/11/08 by Yichao Zhou <broken.zhou AT gmail.com>
+" (*) Fix problems for \[ and \]. Thanks Bruno for reporting.
+" 2017/04/30 by Yichao Zhou <broken.zhou AT gmail.com>
+" (*) Fix a bug between g:tex_noindent_env and g:tex_indent_items
+" Now g:tex_noindent_env='document\|verbatim\|itemize' (Emacs
+" style) is supported. Thanks Miles Wheeler for reporting.
+" 2018/02/07 by Yichao Zhou <broken.zhou AT gmail.com>
+" (*) Make indentation more smart in the normal mode
+" 2020/04/26 by Yichao Zhou <broken.zhou AT gmail.com>
