" Vim plugin for converting a syntax highlighted file to HTML.
" Maintainer: Ben Fritz <fritzophrenic@gmail.com>
" Last Change: 2012 Jul 12
"
" The core of the code is in $VIMRUNTIME/autoload/tohtml.vim and
" $VIMRUNTIME/syntax/2html.vim
"
" TODO: {{{
" * Bug: still a 1px gap throughout the fold column when html_prevent_copy is
" "fn" in some browsers. Specifically, in Chromium on Ubuntu (but not Chrome
" on Windows). Perhaps it is font related?
" * Bug: still some gaps in the fold column when html_prevent_copy contains
" 'd' and showing the whole diff (observed in multiple browsers). Only gaps
" on diff lines though.
" * anchors on each line so you can do file.html#1234 to get to line 1234
" * add a modeline to the generated html to set nofoldenable or fdm=manual
" because syntax folding takes a terribly long time to work with the weird
" formatting the script does.
" * Options for generating the CSS in external style sheets. New :TOcss
" command to convert the current color scheme into a (mostly) generic CSS
" stylesheet which can be re-used. Alternate stylesheet support?
" * Undercurl support via CSS3, with fallback to dotted or something:
" https://groups.google.com/d/topic/vim_use/BzXA6He1pHg/discussion
" * Redo updates for modified default foldtext (v11) when/if the patch is
" accepted to modify it.
" * Test case +diff_one_file-dynamic_folds+expand_tabs-hover_unfold
" +ignore_conceal-ignore_folding+no_foldcolumn+no_pre+no_progress
" +number_lines-pre_wrap-use_css+use_xhtml+whole_filler.xhtml
" does not show the whole diff filler as it is supposed to.
" * Add option for not generating the hyperlink on stuff that looks like a
" URL? Or just color the link to fit with the colorscheme (and only special
" when hovering)?
" * Bug: when 'isprint' is wrong for the current encoding, will generate
" invalid content. Can/should anything be done about this? Maybe a separate
" plugin to correct 'isprint' based on encoding?
" * Check to see if the windows-125\d encodings actually work in Unix without
" the 8bit- prefix. Add prefix to autoload dictionaries for Unix if not.
" * Font auto-detection similar to
" http://www.vim.org/scripts/script.php?script_id=2384 but for a variety of
" platforms.
" * Error thrown when sourcing 2html.vim directly when plugins are not loaded.
" * Pull in code from http://www.vim.org/scripts/script.php?script_id=3113 :
" - listchars support
" - full-line background highlight
" - other?
" * Explicitly trigger IE8+ Standards Mode? Doesn't seem necessary yet.
" * Make it so deleted lines in a diff don't create side-scrolling (get it
" free with full-line background highlight above).
" * Restore open/closed folds and cursor position after processing each file
" with option not to restore for speed increase.
" * Add extra meta info (generation time, etc.)?
" * Tidy up so we can use strict doctype in even more situations
" * Implementation detail: add threshold for writing the lines to the html
" buffer before we're done (5000 or so lines should do it)
" * TODO comments for code cleanup scattered throughout

" Changelog: {{{
"
" 7.3_v12 (this version): Fix modeline mangling to also work for when multiple
" highlight groups make up the start-of-modeline text.
" Improve render time of page with uncopyable regions
" by not using one-input-per-char. Change name of
" uncopyable option from html_unselectable to
" html_prevent_copy. Added html_no_invalid option and
" default to inserting invalid markup for uncopyable
" regions to prevent MS Word from pasting undeletable
" <input> elements. Fix 'cpo' handling (Thilo Six).
" 7.3_v12b1: Add html_unselectable option. Rework logic to
" eliminate post-processing substitute commands in
" favor of doing the work up front. Remove unnecessary
" special treatment of 'LineNr' highlight group. Minor
" speed improvements. Fix modeline mangling in
" generated output so it works for text in the first
" column. Fix missing line number and fold column in
" diff filler lines. Fix that some fonts have a 1px
" gap (using a dirty hack, improvements welcome). Add
" "colorscheme" meta tag. Does NOT include support for
" the new default foldtext added in v11, as the patch
" adding it has not yet been included in Vim.
" 7.3_v11 ( unreleased ): Support new default foldtext from patch by Christian
" Brabandt in
" http://groups.google.com/d/topic/vim_dev/B6FSGfq9VoI/discussion.
" This patch has not yet been included in Vim, thus
" these changes are removed in the next version.
" 7.3_v10 (fd09a9c8468e): Fix error E684 when converting a range wholly inside
" multiple nested folds with dynamic folding on.
" Also fix problem with foldtext in this situation.
" 7.3_v9 (0877b8d6370e): Add html_pre_wrap option active with html_use_css
" and without html_no_pre, default value same as
" 'wrap' option, (Andy Spencer). Don't use
" 'fileencoding' for converted document encoding if
" 'buftype' indicates a special buffer which isn't
" written.
" 7.3_v8 (85c5a72551e2): Add html_expand_tabs option to allow leaving tab
" characters in generated output (Andy Spencer).
" Escape text that looks like a modeline so Vim
" doesn't use anything in the converted HTML as a
" modeline. Bugfixes: Fix folding when a fold starts
" before the conversion range. Remove fold column when
" there are no folds.
" 7.3_v7 (840c3cadb842): see betas released on vim_dev below:
" 7.3_v7b3: Fixed bug, convert Unicode to UTF-8 all the way.
" 7.3_v7b2: Remove automatic detection of encodings that are not
" supported by all major browsers according to
" http://wiki.whatwg.org/wiki/Web_Encodings and
" convert to UTF-8 for all Unicode encodings. Make
" HTML encoding to Vim encoding detection be
" case-insensitive for built-in pairs.
" 7.3_v7b1: Remove use of setwinvar() function which cannot be
" called in restricted mode (Andy Spencer). Use
" 'fencoding' instead of 'encoding' to determine by
" charset, and make sure the 'fenc' of the generated
" file matches its indicated charset. Add charsets for
" all of Vim's natively supported encodings.
" 7.3_v6 (0d3f0e3d289b): Really fix bug with 'nowrapscan', 'magic' and other
" user settings interfering with diff mode generation,
" trailing whitespace (e.g. line number column) when
" using html_no_pre, and bugs when using
" html_hover_unfold.
" 7.3_v5 ( unreleased ): Fix bug with 'nowrapscan' and also with out-of-sync
" folds in diff mode when first line was folded.
" 7.3_v4 (7e008c174cc3): Bugfixes, especially for xhtml markup, and diff mode
" 7.3_v3 (a29075150aee): Refactor option handling and make html_use_css
" default to true when not set to anything. Use strict
" doctypes where possible. Rename use_xhtml option to
" html_use_xhtml for consistency. Use .xhtml extension
" when using this option. Add meta tag for settings.
" 7.3_v2 (80229a724a11): Fix syntax highlighting in diff mode to use both the
" diff colors and the normal syntax colors
" 7.3_v1 (e7751177126b): Add conceal support and meta tags in output
" Pre-v1 baseline: Mercurial changeset 3c9324c0800e
