1" Vim plugin for converting a syntax highlighted file to HTML. 2" Maintainer: Ben Fritz <[email protected]> 3" Last Change: 2013 Jun 12 4" 5" The core of the code is in $VIMRUNTIME/autoload/tohtml.vim and 6" $VIMRUNTIME/syntax/2html.vim 7" 8" TODO: {{{ 9" * Options for generating the CSS in external style sheets. New :TOcss 10" command to convert the current color scheme into a (mostly) generic CSS 11" stylesheet which can be re-used. Alternate stylesheet support? Good start 12" by Erik Falor 13" ( https://groups.google.com/d/topic/vim_use/7XTmC4D22dU/discussion ). 14" * Add optional argument to :TOhtml command to specify mode (gui, cterm, 15" term) to use for the styling. Suggestion by "nacitar". 16" * Add way to override or specify which RGB colors map to the color numbers 17" in cterm. Get better defaults than just guessing? Suggestion by "nacitar". 18" * Disable filetype detection until after all processing is done. 19" * Add option for not generating the hyperlink on stuff that looks like a 20" URL? Or just color the link to fit with the colorscheme (and only special 21" when hovering)? 22" * Bug: Opera does not allow printing more than one page if uncopyable 23" regions is turned on. Possible solution: Add normal text line numbers with 24" display:none, set to display:inline for print style sheets, and hide 25" <input> elements for print, to allow Opera printing multiple pages (and 26" other uncopyable areas?). May need to make the new text invisible to IE 27" with conditional comments to prevent copying it, IE for some reason likes 28" to copy hidden text. Other browsers too? 29" * Bug: still a 1px gap throughout the fold column when html_prevent_copy is 30" "fn" in some browsers. Specifically, in Chromium on Ubuntu (but not Chrome 31" on Windows). Perhaps it is font related? 32" * Bug: still some gaps in the fold column when html_prevent_copy contains 33" 'd' and showing the whole diff (observed in multiple browsers). Only gaps 34" on diff lines though. 35" * Undercurl support via CSS3, with fallback to dotted or something: 36" https://groups.google.com/d/topic/vim_use/BzXA6He1pHg/discussion 37" * Redo updates for modified default foldtext (v11) when/if the patch is 38" accepted to modify it. 39" * Test case +diff_one_file-dynamic_folds+expand_tabs-hover_unfold 40" +ignore_conceal-ignore_folding+no_foldcolumn+no_pre+no_progress 41" +number_lines-pre_wrap-use_css+use_xhtml+whole_filler.xhtml 42" does not show the whole diff filler as it is supposed to? 43" * Bug: when 'isprint' is wrong for the current encoding, will generate 44" invalid content. Can/should anything be done about this? Maybe a separate 45" plugin to correct 'isprint' based on encoding? 46" * Check to see if the windows-125\d encodings actually work in Unix without 47" the 8bit- prefix. Add prefix to autoload dictionaries for Unix if not. 48" * Font auto-detection similar to 49" http://www.vim.org/scripts/script.php?script_id=2384 but for a variety of 50" platforms. 51" * Error thrown when sourcing 2html.vim directly when plugins are not loaded. 52" * Pull in code from http://www.vim.org/scripts/script.php?script_id=3113 : 53" - listchars support 54" - full-line background highlight 55" - other? 56" * Make it so deleted lines in a diff don't create side-scrolling (get it 57" free with full-line background highlight above). 58" * Restore open/closed folds and cursor position after processing each file 59" with option not to restore for speed increase. 60" * Add extra meta info (generation time, etc.)? 61" * Tidy up so we can use strict doctype in even more situations 62" * Implementation detail: add threshold for writing the lines to the html 63" buffer before we're done (5000 or so lines should do it) 64" * TODO comments for code cleanup scattered throughout 65"}}} 66 67if exists('g:loaded_2html_plugin') 68 finish 69endif 70let g:loaded_2html_plugin = 'vim7.3_v14' 71 72" 73" Changelog: {{{ 74" 75" 7.3_v14 (this version): Allow suppressing empty <span> created for line 76" number anchors when line numbers are not included, 77" using g:html_empty_anchors=0. Allow customizing 78" important IDs (like line IDs and fold IDs) using 79" g:html_id_expr evalutated when the buffer conversion 80" is started. 81" 7.3_v13 (2eb30f341e8d): Keep foldmethod at manual in the generated file and 82" insert modeline to set it to manual. 83" Fix bug: diff mode with 2 unsaved buffers creates a 84" duplicate of one buffer instead of including both. 85" Add anchors to each line so you can put '#L123' 86" or '#123' at the end of the URL to jump to line 123 87" (idea by Andy Spencer). Add javascript to open folds 88" to show the anchor being jumped to if it is hidden. 89" Fix XML validation error: &nsbp; not part of XML. 90" Allow TOhtml to chain together with other commands 91" using |. 92" 7.3_v12 (9910cbff5f16): Fix modeline mangling to also work for when multiple 93" highlight groups make up the start-of-modeline text. 94" Improve render time of page with uncopyable regions 95" by not using one-input-per-char. Change name of 96" uncopyable option from html_unselectable to 97" html_prevent_copy. Added html_no_invalid option and 98" default to inserting invalid markup for uncopyable 99" regions to prevent MS Word from pasting undeletable 100" <input> elements. Fix 'cpo' handling (Thilo Six). 101" 7.3_v12b1: Add html_unselectable option. Rework logic to 102" eliminate post-processing substitute commands in 103" favor of doing the work up front. Remove unnecessary 104" special treatment of 'LineNr' highlight group. Minor 105" speed improvements. Fix modeline mangling in 106" generated output so it works for text in the first 107" column. Fix missing line number and fold column in 108" diff filler lines. Fix that some fonts have a 1px 109" gap (using a dirty hack, improvements welcome). Add 110" "colorscheme" meta tag. Does NOT include support for 111" the new default foldtext added in v11, as the patch 112" adding it has not yet been included in Vim. 113" 7.3_v11 ( unreleased ): Support new default foldtext from patch by Christian 114" Brabandt in 115" http://groups.google.com/d/topic/vim_dev/B6FSGfq9VoI/discussion. 116" This patch has not yet been included in Vim, thus 117" these changes are removed in the next version. 118" 7.3_v10 (fd09a9c8468e): Fix error E684 when converting a range wholly inside 119" multiple nested folds with dynamic folding on. 120" Also fix problem with foldtext in this situation. 121" 7.3_v9 (0877b8d6370e): Add html_pre_wrap option active with html_use_css 122" and without html_no_pre, default value same as 123" 'wrap' option, (Andy Spencer). Don't use 124" 'fileencoding' for converted document encoding if 125" 'buftype' indicates a special buffer which isn't 126" written. 127" 7.3_v8 (85c5a72551e2): Add html_expand_tabs option to allow leaving tab 128" characters in generated output (Andy Spencer). 129" Escape text that looks like a modeline so Vim 130" doesn't use anything in the converted HTML as a 131" modeline. Bugfixes: Fix folding when a fold starts 132" before the conversion range. Remove fold column when 133" there are no folds. 134" 7.3_v7 (840c3cadb842): see betas released on vim_dev below: 135" 7.3_v7b3: Fixed bug, convert Unicode to UTF-8 all the way. 136" 7.3_v7b2: Remove automatic detection of encodings that are not 137" supported by all major browsers according to 138" http://wiki.whatwg.org/wiki/Web_Encodings and 139" convert to UTF-8 for all Unicode encodings. Make 140" HTML encoding to Vim encoding detection be 141" case-insensitive for built-in pairs. 142" 7.3_v7b1: Remove use of setwinvar() function which cannot be 143" called in restricted mode (Andy Spencer). Use 144" 'fencoding' instead of 'encoding' to determine by 145" charset, and make sure the 'fenc' of the generated 146" file matches its indicated charset. Add charsets for 147" all of Vim's natively supported encodings. 148" 7.3_v6 (0d3f0e3d289b): Really fix bug with 'nowrapscan', 'magic' and other 149" user settings interfering with diff mode generation, 150" trailing whitespace (e.g. line number column) when 151" using html_no_pre, and bugs when using 152" html_hover_unfold. 153" 7.3_v5 ( unreleased ): Fix bug with 'nowrapscan' and also with out-of-sync 154" folds in diff mode when first line was folded. 155" 7.3_v4 (7e008c174cc3): Bugfixes, especially for xhtml markup, and diff mode 156" 7.3_v3 (a29075150aee): Refactor option handling and make html_use_css 157" default to true when not set to anything. Use strict 158" doctypes where possible. Rename use_xhtml option to 159" html_use_xhtml for consistency. Use .xhtml extension 160" when using this option. Add meta tag for settings. 161" 7.3_v2 (80229a724a11): Fix syntax highlighting in diff mode to use both the 162" diff colors and the normal syntax colors 163" 7.3_v1 (e7751177126b): Add conceal support and meta tags in output 164" Pre-v1 baseline: Mercurial changeset 3c9324c0800e 165"}}} 166 167" Define the :TOhtml command when: 168" - 'compatible' is not set 169" - this plugin was not already loaded 170" - user commands are available. {{{ 171if !&cp && !exists(":TOhtml") && has("user_commands") 172 command -range=% -bar TOhtml :call tohtml#Convert2HTML(<line1>, <line2>) 173endif "}}} 174 175" Make sure any patches will probably use consistent indent 176" vim: ts=8 sw=2 sts=2 noet fdm=marker 177
