VimTeX 2.15

It's way overdue to make another release. There are plenty of bug fixes and a lot of feature improvements. And I'm very glad to see that there are a lot of PR contributions from the community - thanks!

I think the main highlights of this release are:

• The new bib parser in Lua for neovim users. It makes bibtex completion faster - noticably so for those who have large bib files.
• :VimtexCompile now respects options (see #2836 and #2866).
• There are a few improvements to the core syntax that should improve performance.

Important: After this release I will bump the version requirements for both Vim and Neovim! That is, starting now, VimTeX will require Vim version 9.1.0 8.2.3995 (see #2934) or Neovim version 0.9.5. This means that anyone who can not or will not update must stay on this version (the v2.15 tag).

Features

• Compile
  • Allow options for :VimtexCompile (#2836)
  • Respect -jobname option for outfiles in compilers (#2866)
  • Pass file_info argument to out_dir function (#2888)
    • This is a breaking change for anyone who uses a vimscript function for the out_dir key of g:vimtex_compiler_latexmk (or similar), because the function is now passed a single argument.
• Syntax
  • Add option g:vimtex_syntax_match_unicode (#2732)
    • This allows to disable the feature, as it can be slow on large documents.
  • Match <, >, |, / as operators and don't match . (#2776)
  • Add keywords "ISSUE" and "NOTE" to texCommentTodo (#2839)
  • Simplify and improve some regexes to improve performance (#2877)
  • Add conceal support for more superscripts (#2886)
  • Add match for \item labels (#2885)
  • Add vimtex#syntax#add_to_mathzone_ignore (#2929)
  • Improve tcolorbox support (#2789)
  • Add support for quantikz package (#2843, #2842)
  • Initial support for biblatex-chicago package (#2875)
  • Improve sagetex package support (#2926, #2929)
• Viewers
  • viewer.xdo_focus_vim will move mouse pointer to activated window (#2759)
  • Add option g:vimtex_view_skim_no_select to prevent Skim from selecting the text (#2766)
  • Use timer_start instead of :sleep before search for xwin_id (#2802, #2805)
  • Improve g:vimtex_view_use_temp_files (#2819)
    • The old implementation was not working properly and the docs were inconsistent with the implementation. The docs should now be properly consistent and the implementation should be better and more robust.
• UI, commands and mappings
  • Add g:vimtex_ui_method for choosing ui backends
  • Add imap `vp for \varpi (#2797)
• Other
  • Added new (much faster) bib parser in lua (#2786, #2816)
    • Also improved the vimscript implementation of the bib parser
  • Add warning if latexmain specifier is ignored (#2831)
  • Support subsubsubsubsection in toc (#2850)
  • Better fail method for cache encoding errors (#2849)
  • Completion support for volcites with volume (#2878)
  • Fold and toc support for comment package (#2882)

Bug Fixes

• Compile
  • Stop compilers when reloading vimtex (#2760)
  • latexmk: Don't do timeout in pvc mode after inactivity (#2804)
    • By default the -pvc mode will stop working after 30 mins of inactivity. To prevent this, we disable inactivity timeout in the pvc mode with -pvctimeout-. This requires latexmk v4.55 (Jan 2018) or higher.
  • Fix issue when VimtexEventCompile* changes the buffer (#2844)
  • Call quickfix function before issuing autocmd (#2847)
  • Fix regression error in arara compiler (#2862, #2861)
  • Don't create the compiler state if it is disabled (#2905)
• Syntax
  • Minor regression where C was highlighted wrongly (#2761)
  • biblatex package:
    • Add missing \Cite command (#2875)
    • Minor error with concealed volcite (#2875)
  • Minor regression bug in asymptote package (#724)
• Folding
  • Properly handle \items in unexpected item environments (#2771)
• Table of contents (toc)
  • Fix regression bug with preamble toc matcher (#2792, #2787)
  • Minor error in width calculation for label entries in toc
  • Return to original window when we close the toc (#2817)
  • Fix problem where format variable was not defined in labels.vim (#2883)
• Other
  • Ensure globpath_upwards only returns files (#2763)
  • Add health check for zathura_simple viewer (#2796)

VimTeX 2.13

This is a relatively large release that brings several features/improvements and bug fixes, as well as some performance improvements and improved documentation.

There are a few breaking changes. The most important one is likely the change from build_dir to out_dir. Users who specify this option should update their configuration. For example:

" This is now wrong!
let g:vimtex_compiler_latexmk = {
      \ 'build_dir': ...
      \}

" Instead, do this:
let g:vimtex_compiler_latexmk = {

VimTeX 2.11

Time sure seems to pass quickly. Another three months have gone by. As usual, there are a few updates. Nothing huge, but enough to warrant a small release.

VimTeX 2.8

It is again time for a new release. Since v2.7, there's been the normal amount of minor improvements and some refactoring. The main updates I would like to highlight are:

• VimTeX now works even better with inverse search from viewers:
  • I've added :VimtexInverseSearch that can be used by the viewer specific configuration to communicate with VimTeX in a "server agnostic" manner. See :help vimtex-synctex-inverse-search for more info.
  • The documentation on configuration of inverse search with viewers has been rewritten.
• The backend for running external processes and jobs has been rewritten. This is probably not so noticable by users, but it makes it easier to work with for me!

Features

• Viewers
  • Add :VimtexInverseSearch to simplify inverse search configuration in viewers (#2219)
  • Simplify Zathura libsynctex check
• Indentation
  • Only autoindent with 'indentkeys' at start of line (#2227)
  • Allow content before first \item (#2020)
• Performance
  • Reduce wait time for vim.job_stop (#2222)
  • Add cached system call to process handler
  • Avoid a glob() call if possible (#2198)
  • Delay Skim availability check (#2185)
• Syntax
  • Support \nameref (#2208)
  • Allow more styling to g:vimtex_syntax_custom_cmds (#2033, #2224)
  • Conceal support for \(sub)*section (#2022)
  • Add conceal for \[lr][vV]ert (#2186)
  • Minor update to math symbol conceals (#2178)
  • Support for Overleaf's begin|end novalidate (#2171)
  • Improve support for siunitx package (#2167)
• Backend and initialization
  • Ignore 'shell' option for jobstart with neovim (#2220)
  • Improved latexlog quickfix error parsing (#2214)
  • Remove unnecessary option g:vimtex_compiler_progname
  • Add vimtex#env#get_* api functions (#2212)
  • Rewrite process handler (#2195)
    • Simplify and improve structure of job calls
  • Add proper cache validation to all caches (#2206)
  • Parse TeX program directive on request, not only on init (#2168)
  • Improve 'define' option (#2164)

Fixes

  • This was a large change that also improves the documentation for the various viewers and their configuration.
• Use more positive wording for section on integration with other plugins (#1371)

VimTeX 2.7.1

This is a minor release that fixes a critical bug contained in the last commits before v2.7. See #2166 for details.

VimTeX 2.7

The last couple of months have seen several new fixes, updates, and some minor feature improvements. There's been some refactoring, especially to the compiler backend code. I believe there should be no breaking changes (but I'm probably wrong).

Features

• Better compiler status handling, especially for latexmk (#2141)
  • Added option g:vimtex_compiler_silent, which may be useful if one uses compiler status in ones statusline.
  • With this update, it is possible to get a more dynamic compiler status in ones statusline, see #2141 for details.
• Improved syntax support
  • State dependent syntax (#2086)
  • Allow braces in array column specification (#2122)
  • Improve g:vimtex_syntax_nospell_commands (#2118)
  • \bibitem support (#2086)
  • natbib package (#2155)
  • amstex package (#2119)
  • amsthm package and core theorem (#2086)
• Improved Zathura viewer backward search configuration (#2127, #2135)
• Improved vimtex#view#reverse_goto (#2150, #2127)
  • Added event VimtexEventViewReverse to allow more customization after a reverse goto (#2110)
  • This function is useful for slightly improved reverse goto support and is used by default e.g. with the Zathura viewer.
• Improved the compiler output buffer (#2138, #2086)
• Improved pplatex support (#2144)
• Improved how the latexlog quickfix backend handles "Runaway args" (#2136)
• Improved the fold text for environments (#2117, #2128, #2107)
• Added new bib parser backend: bibtexparser (#2103)
• Added completion for \DeclarePairedDelimiter (#2123)
• Added completion of .tikz files for \input{... and friends (#2162)
• Use ftdetect to load VimTeX for all .cls and .tikz files (#2163, #2162)
• Other minor improvements (#2149)
  • Allow more dynamic build_dir config (#2137)
  • Guess language for vlty if necessary (#2128)
  • Improve indentkeys option (#2125)
  • Add cache validation for some cases (#2097)

Fixes

• Fixed problem with quickfix autoclosing (#2161)
• Allow autoload functions to be doc handlers (#2153)
• Fixed issue with starred environments in ToC parser (#2080)
• Fixed LaTeX command parser - don't allow empty lines when gobbling arguments (#2160)
• Fixed issue with extra quotes on Windows (#2139, #1256)
  • Please note that I rely on help of contributors for Windows related issues! I don't use or test VimTeX on a Windows computer myself.
• A lot of other minor fixes (#2165, #2152, #2149, #2138, #2148, #2145, #2142, #2126, #2121, #2120, #2086, #2100)
