&quot; Maintainer: Ben Fritz &lt;fritzophrenic@gmail.com&gt;
&quot; Last Change: 2015 Sep 08
&quot;
&quot; The core of the code is in $VIMRUNTIME/autoload/tohtml.vim and
&quot; $VIMRUNTIME/syntax/2html.vim
&quot;
&quot; TODO: {{{
&quot;   * Options for generating the CSS in external style sheets. New :TOcss
&quot;     command to convert the current color scheme into a (mostly) generic CSS
&quot;     stylesheet which can be re-used. Alternate stylesheet support? Good start
&quot;     by Erik Falor
&quot;     ( https://groups.google.com/d/topic/vim_use/7XTmC4D22dU/discussion ).
&quot;   * Add optional argument to :TOhtml command to specify mode (gui, cterm,
&quot;     term) to use for the styling. Suggestion by &quot;nacitar&quot;.
&quot;   * Add way to override or specify which RGB colors map to the color numbers
&quot;     in cterm. Get better defaults than just guessing? Suggestion by &quot;nacitar&quot;.
&quot;   * Disable filetype detection until after all processing is done.
&quot;   * Add option for not generating the hyperlink on stuff that looks like a
&quot;     URL? Or just color the link to fit with the colorscheme (and only special
&quot;     when hovering)?
&quot;   * Bug: Opera does not allow printing more than one page if uncopyable
&quot;     regions is turned on. Possible solution: Add normal text line numbers with
&quot;     display:none, set to display:inline for print style sheets, and hide
&quot;     &lt;input&gt; elements for print, to allow Opera printing multiple pages (and
&quot;     other uncopyable areas?). May need to make the new text invisible to IE
&quot;     with conditional comments to prevent copying it, IE for some reason likes
&quot;     to copy hidden text. Other browsers too?
&quot;   * Bug: still a 1px gap throughout the fold column when html_prevent_copy is
&quot;     &quot;fn&quot; in some browsers. Specifically, in Chromium on Ubuntu (but not Chrome
&quot;     on Windows). Perhaps it is font related?
&quot;   * Bug: still some gaps in the fold column when html_prevent_copy contains
&quot;     'd' and showing the whole diff (observed in multiple browsers). Only gaps
&quot;     on diff lines though.
&quot;   * Undercurl support via CSS3, with fallback to dotted or something:
&quot;	https://groups.google.com/d/topic/vim_use/BzXA6He1pHg/discussion
&quot;   * Redo updates for modified default foldtext (v11) when/if the patch is
&quot;     accepted to modify it.
&quot;   * Test case +diff_one_file-dynamic_folds+expand_tabs-hover_unfold
&quot;		+ignore_conceal-ignore_folding+no_foldcolumn+no_pre+no_progress
&quot;		+number_lines-pre_wrap-use_css+use_xhtml+whole_filler.xhtml
&quot;     does not show the whole diff filler as it is supposed to?
&quot;   * Bug: when 'isprint' is wrong for the current encoding, will generate
&quot;     invalid content. Can/should anything be done about this? Maybe a separate
&quot;     plugin to correct 'isprint' based on encoding?
&quot;   * Check to see if the windows-125\d encodings actually work in Unix without
&quot;     the 8bit- prefix. Add prefix to autoload dictionaries for Unix if not.
&quot;   * Font auto-detection similar to
&quot;     http://www.vim.org/scripts/script.php?script_id=2384 but for a variety of
&quot;     platforms.
&quot;   * Error thrown when sourcing 2html.vim directly when plugins are not loaded.
&quot;   * Pull in code from http://www.vim.org/scripts/script.php?script_id=3113 :
&quot;	- listchars support
&quot;	- full-line background highlight
&quot;	- other?
&quot;   * Make it so deleted lines in a diff don't create side-scrolling (get it
&quot;     free with full-line background highlight above).
&quot;   * Restore open/closed folds and cursor position after processing each file
&quot;     with option not to restore for speed increase.
&quot;   * Add extra meta info (generation time, etc.)?
&quot;   * Tidy up so we can use strict doctype in even more situations
&quot;   * Implementation detail: add threshold for writing the lines to the html
&quot;     buffer before we're done (5000 or so lines should do it)
&quot;   * TODO comments for code cleanup scattered throughout

&quot; Changelog: {{{
&quot;   7.4_v2  (this version): Fix error raised when converting a diff containing
&quot;                           an empty buffer. Jan Stocker: allow g:html_font to
&quot;                           take a list so it is easier to specfiy fallback
&quot;                           fonts in the generated CSS.
&quot;   7.4_v1  (Vim 7.4.0000): Fix modeline mangling for new &quot;Vim:&quot; format, and
&quot;			    also for version-specific modelines like &quot;vim&gt;703:&quot;.
&quot;
&quot;   7.3 updates: {{{
&quot;   7.3_v14 (Vim 7.3.1246): Allow suppressing line number anchors using
&quot;			    g:html_line_ids=0. Allow customizing
&quot;			    important IDs (like line IDs and fold IDs) using
&quot;			    g:html_id_expr evalutated when the buffer conversion
&quot;			    is started.
&quot;   7.3_v13 (Vim 7.3.1088): Keep foldmethod at manual in the generated file and
&quot;			    insert modeline to set it to manual.
&quot;			    Fix bug: diff mode with 2 unsaved buffers creates a
&quot;			    duplicate of one buffer instead of including both.
&quot;			    Add anchors to each line so you can put '#L123'
&quot;			    or '#123' at the end of the URL to jump to line 123
&quot;			    (idea by Andy Spencer). Add javascript to open folds
&quot;			    to show the anchor being jumped to if it is hidden.
&quot;			    Fix XML validation error: &amp;nsbp; not part of XML.
&quot;			    Allow TOhtml to chain together with other commands
&quot;			    using |.
&quot;   7.3_v12 (Vim 7.3.0616): Fix modeline mangling to also work for when multiple
&quot;			    highlight groups make up the start-of-modeline text.
&quot;			    Improve render time of page with uncopyable regions
&quot;			    by not using one-input-per-char. Change name of
&quot;			    uncopyable option from html_unselectable to
&quot;			    html_prevent_copy. Added html_no_invalid option and
&quot;			    default to inserting invalid markup for uncopyable
&quot;			    regions to prevent MS Word from pasting undeletable
&quot;			    &lt;input&gt; elements. Fix 'cpo' handling (Thilo Six).
&quot;		 7.3_v12b1: Add html_unselectable option. Rework logic to
&quot;			    eliminate post-processing substitute commands in
&quot;			    favor of doing the work up front. Remove unnecessary
&quot;			    special treatment of 'LineNr' highlight group. Minor
&quot;			    speed improvements. Fix modeline mangling in
&quot;			    generated output so it works for text in the first
&quot;			    column. Fix missing line number and fold column in
&quot;			    diff filler lines. Fix that some fonts have a 1px
&quot;			    gap (using a dirty hack, improvements welcome). Add
&quot;			    &quot;colorscheme&quot; meta tag. Does NOT include support for
&quot;			    the new default foldtext added in v11, as the patch
&quot;			    adding it has not yet been included in Vim.
&quot;   7.3_v11 ( unreleased ): Support new default foldtext from patch by Christian
&quot;			    Brabandt in
&quot;			    http://groups.google.com/d/topic/vim_dev/B6FSGfq9VoI/discussion.
&quot;			    This patch has not yet been included in Vim, thus
&quot;			    these changes are removed in the next version.
&quot;   7.3_v10 (Vim 7.3.0227): Fix error E684 when converting a range wholly inside
&quot;			    multiple nested folds with dynamic folding on.
&quot;			    Also fix problem with foldtext in this situation.
&quot;   7.3_v9  (Vim 7.3.0170): Add html_pre_wrap option active with html_use_css
&quot;			    and without html_no_pre, default value same as
&quot;			    'wrap' option, (Andy Spencer). Don't use
&quot;			    'fileencoding' for converted document encoding if
&quot;			    'buftype' indicates a special buffer which isn't
&quot;			    written.
&quot;   7.3_v8  (Vim 7.3.0100): Add html_expand_tabs option to allow leaving tab
&quot;			    characters in generated output (Andy Spencer).
&quot;			    Escape text that looks like a modeline so Vim
&quot;			    doesn't use anything in the converted HTML as a
&quot;			    modeline. Bugfixes: Fix folding when a fold starts
&quot;			    before the conversion range. Remove fold column when
&quot;			    there are no folds.
&quot;   7.3_v7  (Vim 7-3-0063): see betas released on vim_dev below:
&quot;		  7.3_v7b3: Fixed bug, convert Unicode to UTF-8 all the way.
&quot;		  7.3_v7b2: Remove automatic detection of encodings that are not
&quot;			    supported by all major browsers according to
&quot;			    http://wiki.whatwg.org/wiki/Web_Encodings and
&quot;			    convert to UTF-8 for all Unicode encodings. Make
&quot;			    HTML encoding to Vim encoding detection be
&quot;			    case-insensitive for built-in pairs.
&quot;		  7.3_v7b1: Remove use of setwinvar() function which cannot be
&quot;			    called in restricted mode (Andy Spencer). Use
&quot;			    'fencoding' instead of 'encoding' to determine by
&quot;			    charset, and make sure the 'fenc' of the generated
&quot;			    file matches its indicated charset. Add charsets for
&quot;			    all of Vim's natively supported encodings.
&quot;   7.3_v6  (Vim 7.3.0000): Really fix bug with 'nowrapscan', 'magic' and other
&quot;			    user settings interfering with diff mode generation,
&quot;			    trailing whitespace (e.g. line number column) when
&quot;			    using html_no_pre, and bugs when using
&quot;			    html_hover_unfold.
&quot;   7.3_v5  ( unreleased ): Fix bug with 'nowrapscan' and also with out-of-sync
&quot;			    folds in diff mode when first line was folded.
&quot;   7.3_v4  (Vim 7.3.0000): Bugfixes, especially for xhtml markup, and diff mode
&quot;   7.3_v3  (Vim 7.3.0000): Refactor option handling and make html_use_css
&quot;			    default to true when not set to anything. Use strict
&quot;			    doctypes where possible. Rename use_xhtml option to
&quot;			    html_use_xhtml for consistency. Use .xhtml extension
&quot;			    when using this option. Add meta tag for settings.
&quot;   7.3_v2  (Vim 7.3.0000): Fix syntax highlighting in diff mode to use both the
&quot;			    diff colors and the normal syntax colors
&quot;   7.3_v1  (Vim 7.3.0000): Add conceal support and meta tags in output
&quot;}}}

&quot; Define the :TOhtml command when:
&quot; - 'compatible' is not set
&quot; - this plugin was not already loaded
&quot; - user commands are available. {{{
if !&amp;cp &amp;&amp; !exists(&quot;:TOhtml&quot;) &amp;&amp; has(&quot;user_commands&quot;)
  command -range=% -bar TOhtml :call tohtml#Convert2HTML(&lt;line1&gt;, &lt;line2&gt;)
endif &quot;}}}

&quot; Make sure any patches will probably use consistent indent
