bookdown 0.11

BUG FIXES

• The fix for https://stackoverflow.com/q/56061122/559676 in the previous version was incorrect, causing rmd_files to fail when it is a character vector of Rmd filenames (thanks, Joyce Robbins and Hadley Wickham, https://stackoverflow.com/q/56118663/559676).

bookdown 0.10

NEW FEATURES

• Added an argument clean_highlight_tags to html_document2() (thanks, @atusy, #706).

• For HTML output formats such as gitbook, the abstract title (if the abstract is provided) can be customized via the field abstract-title in the YAML frontmatter (thanks, @XiangyunHuang, #715).

BUG FIXES

• Split reference sections in gitbook ignored the sorting definition of the citation style (thanks @GegznaV #661, @crsh #674).

• For the gitbook output format, the content doesn't get the focus when the page is loaded, which makes it fail to respond to keystrokes such as PageUp/PageDown/Up/Down (thanks, @darshanbaral #691, @aronatkins #699).

• For the gitbook output format, when searching for keywords in code blocks, the automatic scroll to keywords doesn't work (thanks, @colearendt, #700).

• The search keyword no longer persists across page loads for different books in the gitbook format (thanks, @aronatkins, #695).

• The keybindings Up and Down (or Enter) in the search input of the gitbook output format work across all pages now; previously they only work on the current page (thanks, @dsblank, #657).

• When performing searching, the gitbook sidebar will only display relevant TOC items that actually take users to the HTML pages containing the search keyword. Previously, some TOC items do not really take users to the search destination but an anchor on a page instead, which can be confusing (thanks, @aronatkins, #696).

• Hyphenated words will be correctly highlighted in the search results now if spaces are used in the search keyword instead of dashes, e.g., you can search for hand-off using the keyword hand off (thanks, @aronatkins, #701).

• When rmd_files is configured in _bookdown.yml, render_book() will fail if the output format is not HTML or LaTeX (thanks, Ladislas Nalborczyk, https://stackoverflow.com/q/56061122/559676).

• The colon after figure/table numbers is missing in Word and EPUB output (thanks, @upton9265, #618).

• Multiple labels on the same line are allowed for Word output (thanks, @mdlincoln @h-k-kan @brooksambrose, #538).

MINOR CHANGES

• Added alt/hover text to icons on the gitbook toolbar (thanks, @aronatkins, #698).

• Added an Information button to the gitbook toolbar to show the keybindings that are otherwise difficult for users to discover without reading the bookdown book (thanks, @aronatkins, #697).

• Added information about the keybindings Enter/Up/Down to the placeholder text and tooltip of the search input in gitbook output (thanks, @pyltime, #660).

bookdown 0.9

BUG FIXES

• The tags for OpenGraph titles in HTML output were not properly closed.

bookdown 0.8

NEW FEATURE

• Added Conjecture to the list of theorem environments.

• In addition to rmd_subdir: true, which searches all subdirectories, you can now provide a list of subdirectories to be recursively searched (#242).

• Added an argument template to gitbook() and epub_book() (thanks, @ThierryO, #570).

• Added an argument table_css to gitbook() to allow customized css for tables. (thanks, @haozhu233, #642)

• You can also add a "history" button on the Gitbook toolbar, which is similar to the "edit" button, but shows the GIT history of a source file instead (thanks, @maelle #638, @noamross, #639).

• Added a quiet argument to serve_book(), so that users can suppress stdout with bookdown::serve_book(quiet = TRUE) (thanks, @hammer, #633).

• For HTML output, the title of the current chapter or section will be added to the page title (in the <title> tag). This will give readers more information when reading the results from search engines or Twitter cards. Previously, all pages would have identical titles (thanks, @benwhalley and @batpigandme, #544).

BUG FIXES

• HTML output formats such as gitbook and html_document2 won't work when only unnumbered parts (i.e., # (PART\*)) are used (thanks, @tjmahr, #575).

• Previously the rmd_files parameter in _bookdown.yml would override rmd_subdir, but now both parameters can be used simultaneously (thanks, @ellisvalentiner, #600).

• Resources with URL encoded special characters are now correctly copied to the output directory (thanks, @AshesITR, #622).

• serve_book() can now be used without error when rstudioapi is installed but RStudio is not being used (thanks, @jimhester, #637).

• Text references via (ref:label) for bookdown::pdf_document() doesn't always work (thanks, @brendanf, #616).

bookdown 0.7

MINOR CHANGES

• Added a new dependency tinytex to build PDF, and xfun for some utility functions.

• Added the ability to share documents on LinkedIn with the gitbook output format (thanks, @WeeBeasties, #523, https://stackoverflow.com/q/48494097/559676).

CHANGES IN bookdown VERSION 0.6

NEW FEATURES

• Added an argument config_file to render_book() so that one can specify a custom config file; the default config file is still _bookdown.yml (thanks, @stephlocke, #465).

• Added a global option bookdown.preview.cutoff (defaults to 30) for the preview mode render_book(preview = TRUE): when the number of lines of a chapter is smaller or equal to this number, the full chapter is included in the preview; otherwise, only the section titles are extracted from the chapter for preview.

BUG FIXES

• Various compatibility issues with Pandoc 2.0 (thanks, @maxheld83 #479, @jerrythomas #481, @Hantabaru #483, @dataopt #504, and #478).

• split_by = 'section' does not work completely correctly for the HTML output formats like gitbook (thanks, @dataopt, #502).

CHANGES IN bookdown VERSION 0.5

NEW FEATURES

• Added support for two more environments: Exercises and Solutions (thanks, @dshuman1, #423).

• If the Rmd file merged from all chapters exists and you are sure it can be safely deleted, you can set an option delete_merged_file to true in _bookdown.yml (thanks, @dmenne, #442).

BUG FIXES

• The book cannot be properly rendered when the option book_filename in _bookdown.yml contains a dot (thanks, @pinusm, #410).

• Proof and Remark blocks do not work well for EPUB output (thanks, @mamaciasq, #443).

• When split_by = 'section' for the gitbook output format, navigation buttons are missing on the page before the appendix (thanks, @dataopt, #409).

MINOR CHANGES

• The label prefix for Example blocks was changed from ex: to exm:.

CHANGES IN bookdown VERSION 0.4

NEW FEATURES

• Added special syntax for unnumbered part headers: # (PART\*). Numbered parts should be written after # (PART) as before (thanks, @brooksambrose, http://stackoverflow.com/q/43688902/559676).

• The gitbook output format also supports abstract in YAML now (thanks, @maxheld83, #311).

• For the gitbook output format, the downloads option in config supports rmd now (e.g. download: ["pdf", "epub", "rmd"]) if the edit link has been specified and is a link to Github (thanks, @coatless, #330).

• You can set the global R option bookdown.post.latex via options() to be a function to post-process the LaTeX output of the pdf_book format; see ?bookdown::pdf_book for details (thanks, @nicksolomon, #373).

BUG FIXES

• The HTML output file is not moved to the output directory when split_by = 'none' in bookdown::gitbook or bookdown::html_book (http://stackoverflow.com/q/40976073/559676).

• The YAML option includes: before_body works correctly for gitbook output now (thanks, @benmarwick, #267).

• Theorem environments are not defined for LaTeX output unless a theorem block is present (thanks, @JeffreyRacine, #291).

• For remark and proof blocks, the chunk option name did not work correctly for non-LaTeX output (thanks, @ugroempi, #347).

• Some text references do not work for HTML and Word output (thanks, @ugroempi, #363).

• The option chapter_name in _bookdown.yml does not work when it is specified as a function (thanks, @tzerk, 0c05c38).

• External assets such as fonts/css files should never be wiped when rendering a book to HTML (thanks, @nicholaelaw, #398).

MINOR CHANGES

• The daemon argument was removed from serve_book(), but you can still pass it to servr::httw() via the ... argument.

• Added a small space (padding) to the right of section numbers in gitbook output, so that the section numbers are better separated from the titles (thanks, @aronatkins, #367).

CHANGES IN bookdown VERSION 0.3

NEW FEATURES

• Added a Github button in the group of sharing buttons on the toolbar. By default, this button is not displayed. You have to set github: yes under sharing in the gitbook configurations (https://bookdown.org/yihui/bookdown/html.html) and specify your Github repo using the top-level option github-repo in the YAML metadata of index.Rmd, e.g. github-repo: rstudio/bookdown.
• The appendix heading will be preserved in bookdown::html_document2 output, e.g. if you have # (APPENDIX) Appendix {-} in your document, you will see the heading Appendix in the output. Previously it was removed.
• Parts in HTML output are also be numbered using roman numerals like LaTeX/PDF output.

BUG FIXES

• Added support for cross-referencing equations in multi-page HTML output and EPUB; see https://bookdown.org/yihui/bookdown/ for the syntax (thanks, @deleeuw, #85).
• Rmd files can live in subdirectories if you use the Merge-and-Knit approach (the default), and they will be found if the configuration option rmd_subdir is true in _bookdown.yml (thanks, @leobuchignani, #205).

MAJOR CHANGES

• The force_knit argument of render_book() was removed (to avoid confusion when switching output formats).

MINOR CHANGES

• The merged R Markdown file will not be deleted if rendering failed so you can debug with this file (http://stackoverflow.com/q/38883222/559676).
• The configurations edit: text and chapter_name have been moved from the top-level options to the sub-options of language: ui in _bookdown.yml. See https://bookdown.org/yihui/bookdown/internationalization.html

BUG FIXES

• Figures are not correctly numbered in Word output using the bookdown::word_document2() format (thanks, @byzheng, #158).
• For the "Knit and Merge" approach (new_session: yes in _bookdown.yml), certain parts like figures may not show up when switching from one output format to another (e.g. from HTML to LaTeX).
• The rmd_files option in _bookdown.yml does not work when it is a list of html and latex options (thanks, @ismayc, #177).
