29 " tab occurs after a syntax match which in turn | |
30 " comes after previously expanded tabs. | |

32 " destination file to ignore FileType events; | |
33 " speeds up processing when the destination file | |

31885 | 35 " - Fix SourceForge issue #20: progress bar could not be |

15033 | 166 " TODO: {{{ |
167 " * Check the issue tracker: | |
31885 | 168 " https://sourceforge.net/p/vim-tohtml/issues/search/?q=%21status%3Aclosed |
15033 | 169 " * Options for generating the CSS in external style sheets. New :TOcss |
170 " command to convert the current color scheme into a (mostly) generic CSS | |
171 " stylesheet which can be re-used. Alternate stylesheet support? Good start | |
172 " by Erik Falor | |
173 " ( https://groups.google.com/d/topic/vim_use/7XTmC4D22dU/discussion ). | |
174 " * Add optional argument to :TOhtml command to specify mode (gui, cterm, | |
175 " term) to use for the styling. Suggestion by "nacitar". | |
176 " * Add way to override or specify which RGB colors map to the color numbers | |
177 " in cterm. Get better defaults than just guessing? Suggestion by "nacitar". | |
178 " * Disable filetype detection until after all processing is done. | |
179 " * Add option for not generating the hyperlink on stuff that looks like a | |
180 " URL? Or just color the link to fit with the colorscheme (and only special | |
181 " when hovering)? | |
182 " * Bug: Opera does not allow printing more than one page if uncopyable | |
183 " regions is turned on. Possible solution: Add normal text line numbers with | |
184 " display:none, set to display:inline for print style sheets, and hide | |
185 " <input> elements for print, to allow Opera printing multiple pages (and | |
186 " other uncopyable areas?). May need to make the new text invisible to IE | |
187 " with conditional comments to prevent copying it, IE for some reason likes | |
188 " to copy hidden text. Other browsers too? | |
189 " * Bug: still a 1px gap throughout the fold column when html_prevent_copy is | |
190 " "fn" in some browsers. Specifically, in Chromium on Ubuntu (but not Chrome | |
191 " on Windows). Perhaps it is font related? | |
192 " * Bug: still some gaps in the fold column when html_prevent_copy contains | |
193 " 'd' and showing the whole diff (observed in multiple browsers). Only gaps | |
194 " on diff lines though. | |
195 " * Undercurl support via CSS3, with fallback to dotted or something: | |
196 " https://groups.google.com/d/topic/vim_use/BzXA6He1pHg/discussion | |
197 " * Redo updates for modified default foldtext (v11) when/if the patch is | |
198 " accepted to modify it. | |
199 " * Test case +diff_one_file-dynamic_folds+expand_tabs-hover_unfold | |
200 " +ignore_conceal-ignore_folding+no_foldcolumn+no_pre+no_progress | |
201 " +number_lines-pre_wrap-use_css+use_xhtml+whole_filler.xhtml | |
202 " does not show the whole diff filler as it is supposed to? | |
203 " * Bug: when 'isprint' is wrong for the current encoding, will generate | |
204 " invalid content. Can/should anything be done about this? Maybe a separate | |
205 " plugin to correct 'isprint' based on encoding? | |
206 " * Check to see if the windows-125\d encodings actually work in Unix without | |
207 " the 8bit- prefix. Add prefix to autoload dictionaries for Unix if not. | |
208 " * Font auto-detection similar to | |
209 " http://www.vim.org/scripts/script.php?script_id=2384 but for a variety of | |
210 " platforms. | |
211 " * Pull in code from http://www.vim.org/scripts/script.php?script_id=3113 : | |
212 " - listchars support | |
213 " - full-line background highlight | |
214 " - other? | |
215 " * Make it so deleted lines in a diff don't create side-scrolling (get it | |
216 " free with full-line background highlight above). | |
217 " * Restore open/closed folds and cursor position after processing each file | |
218 " with option not to restore for speed increase. | |
219 " * Add extra meta info (generation time, etc.)? | |
220 " * Tidy up so we can use strict doctype in even more situations | |
221 " * Implementation detail: add threshold for writing the lines to the html | |
222 " buffer before we're done (5000 or so lines should do it) | |
223 " * TODO comments for code cleanup scattered throughout | |
