[lsp-mode] [Texlab] 2 How to Use? ============= - First, you have to install Texlab. Please install this [here]. - Next, you should make `lsp-mode' available. See [lsp-mode]. - Now, you can use Language Server Protocol (LSP) on (la)tex-mode or yatex-mode just to evaluate this: ,---- | 1 (add-to-list 'load-path "/path/to/lsp-latex") | 2 (require 'lsp-latex) | 3 ;; "texlab" executable must be located at a directory contained in `exec-path'. | 4 ;; If you want to put "texlab" somewhere else, | 5 ;; you can specify the path to "texlab" as follows: | 6 ;; (setq lsp-latex-texlab-executable "/path/to/texlab") | 7 | 8 (with-eval-after-load "tex-mode" | 9 (add-hook 'tex-mode-hook 'lsp) | 10 (add-hook 'latex-mode-hook 'lsp)) | 11 | 12 ;; For YaTeX | 13 (with-eval-after-load "yatex" | 14 (add-hook 'yatex-mode-hook 'lsp)) | 15 | 16 ;; For bibtex | 17 (with-eval-after-load "bibtex" | 18 (add-hook 'bibtex-mode-hook 'lsp)) `---- [here] [lsp-mode] 3 Variables =========== 3.1 `lsp-latex-texlab-executable' ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Where Texlab server executable located. 3.2 `lsp-latex-texlab-executable-argument-list' ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Argument list passed to Texlab server. 3.3 Others, provided by texlab server ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ These variables are connected to Texlab configuration variables.

It use [`latexmk'] by default, so add `.latexmkrc' if you want to customize latex commands or options. You can change build command and option to other such as `make', by changing `lsp-latex-build-executable' and `lsp-latex-build-args'. This command build asynchronously by default, while it build synchronously with prefix argument(`C-u'). [`latexmk'] 5 Workspace commands ==================== These commands are connected to Texlab Workspace commands. See also [Texlab official wiki]. Custom variable in Emacs Configuration provided by Texlab ------------------------------------------------------------------- lsp-latex-clean-auxiliary texlab.cleanAuxiliary lsp-latex-clean-artifacts texlab.cleanArtifacts lsp-latex-change-environment texlab.changeEnvironment lsp-latex-find-environments texlab.findEnvironments lsp-latex-show-dependency-graph texlab.showDependencyGraph lsp-latex-cancel-build texlab.cancelBuild [Texlab official wiki] 5.1 `lsp-latex-clean-auxiliary' ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This command removes LaTeX auxiliary files. It will run `latexmk -c' in the project. 5.2 `lsp-latex-clean-artifacts' ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This command removes LaTeX auxiliary files and artifacts It will run `latexmk -C' in the project. 5.3 `lsp-latex-change-environment' ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This command replaces enviroment name to NEW-NAME in current position. This edits most-inner environment containing the current position. 5.4 `lsp-latex-find-environments' ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This function get list of environments containing the current point. Each element of the list is `lsp-latex-environment-location' instance. See the docstring of `lsp-latex-environment-location'. 5.4.1 `lsp-latex-complete-environment' -------------------------------------- This function reads environment name from minibuffer and returns `lsp-latex-environment-location' instance. It takes three arguments, `BUFFER', `POINT', `PROMPT'. `PROMPT' is used as prompt for `consult--read', which is wrapper of `completing-read'. `BUFFER' and `POINT' specify basis to find environments. 5.5 `lsp-latex-show-dependency-graph' ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Show dependency graph written by DOT format. [`graphviz-dot-mode'] is needed if you needs syntax highlights or a graphical image. [`graphviz-dot-mode'] 5.6 `lsp-latex-cancel-build' ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This command request Texlab to cancel the proceeding build. 6 Commands with `lsp-latex-complete-environment' ================================================ `lsp-latex-find-environments', which is interface for `texlab.FindEnvironments', does nothing but returns list of environments. So this package provide some additional commands to utilize it. 6.1 `lsp-latex-goto-environment' ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Go to selected environment containing the current point. 6.2 `lsp-latex-select-and-change-environment' ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Change name of selected environment to NEW-NAME. 7 Forward/inverse search ======================== Forward search and inverse search are available. See also [Texlab official wiki]. [Texlab official wiki] 7.1 Forward search ~~~~~~~~~~~~~~~~~~ You can move from Emacs to current position on pdf viewer by the function `lsp-latex-forward-search'. To use, you should set `lsp-latex-forward-search-executable' and `lsp-latex-forward-search-args' according to your pdf viewer. You can see [Texlab official wiki], but you should replace some VSCode words with Emacs words. `latex.forwardSearch.executable' should be replaced with `lsp-latex-forward-search-executable', and `latex.forwardSearch.args' with `lsp-latex-forward-search-args'. You should setq each variable instead of writing like json, and vector in json is replaced to list in Emacs Lisp. So the json: ,---- | { | "texlab.forwardSearch.executable": "FavoriteViewer", | "texlab.forwardSearch.args": [ "%p", "%f", "%l" ] | } `---- should be replaced with the Emacs Lisp code: ,---- | (setq lsp-latex-forward-search-executable "FavoriteViewer") | (setq lsp-latex-forward-search-args '("%p" "%f" "%l")) `---- In `lsp-latex-forward-search-args', the string "%f" is replaced with "The path of the current TeX file", "%p" with "The path of the current PDF file", "%l" with "The current line number", by Texlab (see [Forward search arg section in Texlab official wiki]). For example of SumatraPDF, write in init.el: ,---- | (setq lsp-latex-forward-search-executable "C:/Users/{User}/AppData/Local/SumatraPDF/SumatraPDF.exe") | (setq lsp-latex-forward-search-args '("-reuse-instance" "%p" "-forward-search" "%f" "%l")) `---- while VSCode config with json (see [Texlab official wiki]) is: ,---- | { | "texlab.forwardSearch.executable": "C:/Users/{User}/AppData/Local/SumatraPDF/SumatraPDF.exe", | "texlab.forwardSearch.args": [ | "-reuse-instance", | "%p", | "-forward-search", | "%f", | "%l" | ] | } `---- Then, you can jump to the current position on pdf viewer by command `lsp-latex-forward-search'. [Texlab official wiki] [Forward search arg section in Texlab official wiki] [Texlab official wiki] 7.2 Inverse search ~~~~~~~~~~~~~~~~~~ You can go to the current position on Emacs from pdf viewer. Whatever pdf viewer you use, you should start Emacs server by writing in init.el: ,---- | (server-start) `---- Then, you can jump to line {{LINE-NUMBER}} in file named {{FILENAME}} with the command: ,---- | 1 emacsclient +{{LINE-NUMBER}} {{FILENAME}} `---- {{LINE-NUMBER}} and {{FILENAME}} should be replaced with line number and filename you want to jump to. Each pdf viewer can provide some syntax to replace. For example of SmatraPDF (see [Texlab official wiki]), "Add the following line to your SumatraPDF settings file (Menu -> Settings -> Advanced Options):" ,---- | 1 InverseSearchCmdLine = C:\path\to\emacsclient.exe +%l %f `---- Then, "You can execute the search by pressing Alt+DoubleClick in the PDF document". [Texlab official wiki] 7.3 Examples ~~~~~~~~~~~~ These examples are according to [Texlab official wiki]. Especially, quoted or double-quoted sentences are citation from [Texlab official wiki]. [Texlab official wiki] 7.3.1 SumatraPDF ---------------- We highly recommend SumatraPDF on Windows because Adobe Reader locks the opened PDF file and will therefore prevent further builds. * 7.3.1.1 Forward search Write to init.el: ,---- | (setq lsp-latex-forward-search-executable "C:/Users/{User}/AppData/Local/SumatraPDF/SumatraPDF.exe") | (setq lsp-latex-forward-search-args '("-reuse-instance" "%p" "-forward-search" "%f" "%l")) `---- * 7.3.1.2 Inverse Search Add the following line to your [SumatraPDF] settings file (Menu -> Settings -> Advanced Options): ,---- | 1 InverseSearchCmdLine = C:\path\to\emacsclient.exe +%l "%f" `---- You can execute the search by pressing `Alt+DoubleClick' in the PDF document. [SumatraPDF] 7.3.2 Evince ------------ The SyncTeX feature of [Evince] requires communication via D-Bus. In order to use it from the command line, install the [evince-synctex] script. [Evince] [evince-synctex] * 7.3.2.1 Forward search Write to init.el: ,---- | (setq lsp-latex-forward-search-executable "evince-synctex") | (setq lsp-latex-forward-search-args '("-f" "%l" "%p" "\"emacsclient +%l %f\"")) `---- * 7.3.2.2 Inverse search The inverse search feature is already configured if you use `evince-synctex'. You can execute the search by pressing `Ctrl+Click' in the PDF document. 7.3.3 Okular ------------ * 7.3.3.1 Forward search Write to init.el: ,---- | (setq lsp-latex-forward-search-executable "okular") | (setq lsp-latex-forward-search-args '("--unique" "file:%p#src:%l%f")) `---- * 7.3.3.2 Inverse search Change the editor of Okular (Settings -> Configure Okular... -> Editor) to "Custom Text Editor" and set the following command: ,---- | emacsclient +%l "%f" `---- You can execute the search by pressing `Shift+Click' in the PDF document. 7.3.4 Zathura ------------- * 7.3.4.1 Forward search Write to init.el: ,---- | (setq lsp-latex-forward-search-executable "zathura") | (setq lsp-latex-forward-search-args '("--synctex-forward" "%l:1:%f" "%p")) `---- * 7.3.4.2 Inverse search Add the following lines to your `~/.config/zathura/zathurarc' file: ,---- | 1 set synctex true | 2 set synctex-editor-command "emacsclient +%{line} %{input}" `---- You can execute the search by pressing `Alt+Click' in the PDF document. 7.3.5 qpdfview -------------- * 7.3.5.1 Forward search Write to init.el: ,---- | (setq lsp-latex-forward-search-executable "qpdfview") | (setq lsp-latex-forward-search-args '("--unique" "%p#src:%f:%l:1")) `---- * 7.3.5.2 Inverse search Change the source editor setting (Edit -> Settings... -> Behavior -> Source editor) to: ,---- | 1 emacsclient +%2 "%1" `---- and select a mouse button modifier (Edit -> Settings... -> Behavior -> Modifiers -> Mouse button modifiers -> Open in Source Editor)of choice. You can execute the search by pressing Modifier+Click in the PDF document. 7.3.6 Skim ---------- We recommend [Skim] on macOS since it is the only native viewer that supports SyncTeX. Additionally, enable the "Reload automatically" setting in the Skim preferences (Skim -> Preferences -> Sync -> Check for file changes). [Skim] * 7.3.6.1 Forward search Write to init.el: ,---- | (setq lsp-latex-forward-search-executable "/Applications/Skim.app/Contents/SharedSupport/displayline") | (setq lsp-latex-forward-search-args '("%l" "%p" "%f")) `---- "If you want Skim to stay in the background after executing the forward search, you can add the `-g' option to" `lsp-latex-forward-search-args'. * 7.3.6.2 Inverse search Select Emacs preset "in the Skim preferences (Skim -> Preferences -> Sync -> PDF-TeX Sync support). You can execute the search by pressing `Shift+⌘+Click' in the PDF document." 7.3.7 `pdf-tools' integration ----------------------------- If you want to use forward search with `pdf-tools', follow the setting: ,---- | ;; Start Emacs server | (server-start) | ;; Turn on SyncTeX on the build. | ;; If you use `lsp-latex-build', it is on by default. | ;; If not (for example, YaTeX or LaTeX-mode building system), | ;; put to init.el like this: | (setq tex-command "platex --synctex=1") | | ;; Setting for pdf-tools | (setq lsp-latex-forward-search-executable "emacsclient") | (setq lsp-latex-forward-search-args | '("--eval" | "(lsp-latex-forward-search-with-pdf-tools \"%f\" \"%p\" \"%l\")")) `---- Inverse research is not provided by Texlab, so please use `pdf-sync-backward-search-mouse'. 8 License ========= This package is licensed by GPLv3.
