I am attempting to install language tool on my texstudio distribution in order to check my grammar. Currently, I am following this guide to install Language tool. http://wiki.languagetool.org/checking-la-tex-with-languagetool

The problem is, I cannot find languagetool-standalone.jar nor LanguageToolGUI.jar in any of the downloads at the bottom of http://languagetool.org/ . Can anyone tell me where can I locate these files?

  • Isn't it just the standalone desktop tool?

  • I get an error just as Foad did, with error msg = LT current status: error. Then I changed the URL to localhost\8081/v2/check. Then LT current status: working is shown.

I am using TeXstudio with Language Tool under Windows 7 without any problems. The entry in the wiki is not valid for the newest version. You need to use the languagetool.jar. Then everything should work. All the other files you mentionend, existed in previous version of the tool, but are now removed. See the changelog.

    Which file do I download? Also, do you know which are the exact names of the files? Because I cannot find anything about filenames being changed in the changelog (it must be too far back that it has been removed)

    @WetFeet Just download the newest version as a zip, which is 2.4.1, and then everything should be fine. Unpack the zip-file in the directory you like and start the languagetool.jar. The change of the file names occurred in the recent version 2.4

  • How do I start the languagetool.jar? When I double click it my computer opens it like a compressed folder.

  • You need to install the java jre first to execute jar files.

You may follow the steps as shown in the clip (https://www.youtube.com/watch?v=VYIY7bbSv4Q):

  1. Download and install Java of 32 or 64 bits version from http://www.java.com/en/
  2. Download Language tool from https://dev.languagetool.org/http-server (Old versions: https://languagetool.org/)
  3. Unzip the downloaded package and open languagetool.jar. Open "Text Checking"-> "Options", tick "Run as server on port" and set it as 8081. enter image description here
  4. Open Texstudio and click on "Options"->"Configure Texstudio". Check the "Inline Checking" in "Editor" section. Make sure that "Show advanced options" in the lower left corner is checked, and modify the "LanguageTool" in "Grammar" section as below. Specifically, set "Server URL" as "http://localhost:8081", "LT Path" and "Java" respectively as the paths of "languagetool-server.jar" (Old Version "languagetool.jar") and "java.exe". enter image description here

To test this, (re)start texstudio, and check whether the Languagetool is running on the desired port by navigating to http://localhost:8081/ on your machine.

Note that the TexStudio 2.12.6 does not work with Languagetools version > 3.5 since the http API is no longer offered. Fixed in a later version.

    It's far better to include the relevant parts of what you reference...

  • Hi @Werner the clip is just as short as 3m; and an elaboration seems to be redundant and irreverent of the originality.

    To update. In TeXstudio config, "Language check", "Server URL" must have: "localhost:8081/v2/check".

The answer for Linux Users ;)

  1. Download the LanguageTool for desktop
  2. Unpack the downloaded .zip file (just provisionally) in your download folder. The terminal command is, for example, unzip LanguageTool-stable.zip
  3. In the unpacked folder you will find the version subfolder LanguageTool-5.5 (of course the exact name depends on the LanguageTool version)
  4. Move the version subfolder to an appropriate directory. I personally recommend the root directory /opt. Therefore, write in terminal sudo mv LanguageTool-5.5 /opt
  5. Adapt the Settings in Texstudio (Options > Configure TeXstudio > Language Checking > LanguageTool) There you introduce following: (see picture)

a. The path of the languagetool-server.jar file in the LT Path field. In our case we type: /opt/LanguageTool-5.5/languagetool-server.jar

b. The path to the java platform in the Java field. In our case we type: /usr/bin/java (of course it is prerequisite that you hava java installed)

enter image description here

Thanks to @shivang-patel for providing the updated link to the application. And to @soham for giving the new name of the .jar file.

In old versions of LanguageTool (e.g., version 4.7) the name of the file is languagetool.jar

    When I did your approach localhost:8081 returns: Error: Missing arguments for LanguageTool API. Please see https://languagetool.org/http-api/swagger-ui/#/default@loved.by.Jesus

    You just need to give languagetool-server.jar in the LT path, instead of languagetool.jar. Save your 15 mins.

This is a recent and more detailed solution for Windows users.

  1. Make sure the last version of TeXstudio is downloaded from its website.
  2. Download the English dictionary (*.oxt) from here to the directory C:\Program Files (x86)\TeXstudio\dictionaries.
  3. Download languagetools (*.zip) from its website (I used D:\Applications\LanguageTool-4.8 as its directory).
  4. Navigate to LanguageTool directory, then open languagetool.jar. Go to Text Checking > Options, then check Run as server op port and type the port number 8081. Click OK and close.

enter image description here

  1. Open TeXstudio and go to Options > Configure TeXstudio > Language Checking while making sure the Show Advanced Options is checked.
  2. Click on Import Dictionary... and navigate to C:\Program Files (x86)\TeXstudio\dictionaries, then choose the dictionary *.oxt you downloaded.
  3. Make sure the default languae is selected (e.g. en_US), and the thesaurus is selected from the same directory (e.g. th_en_US_v2.dat).

enter image description here

  1. Check Start LanguageTool if not running.
  2. Set the values Server URL, Java, LT Path and LT Arguments to http://localhost:8081/, java (as recommended here), <directory of LanguageTool*-*>\languagetool.jar and org.languagetool.server.HTTPServer -p 8081 --languagemodel --allow-origin "*" (as recommended here), respectively.

enter image description here

In order to make sure everything is fine, click on Help > Check LanguageTool in TeXstudio. The output should be something like this

enter image description here
