" Changelog: {{{
|
|
" 8.1_v2 (this version): - Fix Bitbucket issue #19: fix calculation of tab
|
|
" stop position to use in expanding a tab, when that
|
|
" tab occurs after a syntax match which in turn
|
|
" comes after previously expanded tabs.
|
|
" - Set eventignore while splitting a window for the
|
|
" destination file to ignore FileType events;
|
|
" speeds up processing when the destination file
|
|
" already exists and HTML highlight takes too long.
|
|
" - Fix Bitbucket issue #20: progress bar could not be
|
|
" seen when DiffDelete background color matched
|
|
" StatusLine background color. Added TOhtmlProgress
|
|
" highlight group for manual user override, but
|
|
" calculate it to be visible compared to StatusLine
|
|
" by default.
|
|
" - Fix Bitbucket issue #1: Remove workaround for old
|
|
" browsers which don't support 'ch' CSS unit, since
|
|
" all modern browsers, including IE>=9, support it.
|
|
" - Fix Bitbucket issue #10: support termguicolors
|
|
" - Fix Bitbucket issue #21: default to using
|
|
" generated content instead of <input> tags for
|
|
" uncopyable text, so that text is correctly
|
|
" prevented from being copied in chrome. Use
|
|
" g:html_use_input_for_pc option to control the
|
|
" method used.
|
|
" - Switch to HTML5 to allow using vnu as a validator
|
|
" in unit test.
|
|
" - Fix fallback sizing of <input> tags for browsers
|
|
" without "ch" support.
|
|
" - Fix cursor on unselectable diff filler text.
|
|
" 8.1_v1 (Vim 8.1.0528): - Fix Bitbucket issue #6: Don't generate empty
|
|
" script tag.
|
|
" - Fix Bitbucket issue #5: javascript should
|
|
" declare variables with "var".
|
|
" - Fix Bitbucket issue #13: errors thrown sourcing
|
|
" 2html.vim directly when plugins not loaded.
|
|
" - Fix Bitbucket issue #16: support 'vartabstop'.
|
|

|
|
" 7.4 updates: {{{
|
|
" 7.4_v2 (Vim 7.4.0899): Fix error raised when converting a diff containing
|
|
" an empty buffer. Jan Stocker: allow g:html_font to
|
|
" take a list so it is easier to specfiy fallback
|
|
" fonts in the generated CSS.
|
|
" 7.4_v1 (Vim 7.4.0000): Fix modeline mangling for new "Vim:" format, and
|
|
" also for version-specific modelines like "vim>703:".
|
|
"}}}
|
|
"
|
|
" 7.3 updates: {{{
|
|
" 7.3_v14 (Vim 7.3.1246): Allow suppressing line number anchors using
|
|
" g:html_line_ids=0. Allow customizing
|
|
" important IDs (like line IDs and fold IDs) using
|
|
" g:html_id_expr evaluated when the buffer conversion
|
|
" is started.
|
|
" 7.3_v13 (Vim 7.3.1088): Keep foldmethod at manual in the generated file and
|
|
" insert modeline to set it to manual.
|
|
" Fix bug: diff mode with 2 unsaved buffers creates a
|
|
" duplicate of one buffer instead of including both.
|
|
" Add anchors to each line so you can put '#L123'
|
|
" or '#123' at the end of the URL to jump to line 123
|
|
" (idea by Andy Spencer). Add javascript to open folds
|
|
" to show the anchor being jumped to if it is hidden.
|
|
" Fix XML validation error: &nsbp; not part of XML.
|
|
" Allow TOhtml to chain together with other commands
|
|
" using |.
|
|
" 7.3_v12 (Vim 7.3.0616): 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 (Vim 7.3.0227): 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 (Vim 7.3.0170): 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 (Vim 7.3.0100): 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 (Vim 7-3-0063): 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 (Vim 7.3.0000): 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 (Vim 7.3.0000): Bugfixes, especially for xhtml markup, and diff mode
|
|
" 7.3_v3 (Vim 7.3.0000): 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 (Vim 7.3.0000): Fix syntax highlighting in diff mode to use both the
|
|
" diff colors and the normal syntax colors
|
|
" 7.3_v1 (Vim 7.3.0000): Add conceal support and meta tags in output

" TODO: {{{
|
|
" * Check the issue tracker:
|
|
" https://bitbucket.org/fritzophrenic/vim-tohtml/issues?status=new&status=open
|
|
" * 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? Good start
|
|
" by Erik Falor
|
|
" ( https://groups.google.com/d/topic/vim_use/7XTmC4D22dU/discussion ).
|
|
" * Add optional argument to :TOhtml command to specify mode (gui, cterm,
|
|
" term) to use for the styling. Suggestion by "nacitar".
|
|
" * Add way to override or specify which RGB colors map to the color numbers
|
|
" in cterm. Get better defaults than just guessing? Suggestion by "nacitar".
|
|
" * Disable filetype detection until after all processing is done.
|
|
" * 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: Opera does not allow printing more than one page if uncopyable
|
|
" regions is turned on. Possible solution: Add normal text line numbers with
|
|
" display:none, set to display:inline for print style sheets, and hide
|
|
" <input> elements for print, to allow Opera printing multiple pages (and
|
|
" other uncopyable areas?). May need to make the new text invisible to IE
|
|
" with conditional comments to prevent copying it, IE for some reason likes
|
|
" to copy hidden text. Other browsers too?
|
|
" * 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.
|
|
" * 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?
|
|
" * 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.
|
|
" * Pull in code from http://www.vim.org/scripts/script.php?script_id=3113 :
|
|
" - listchars support
|
|
" - full-line background highlight
|
|
" - other?
|
|
" * 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
