Where to find dictionaries for other languages for IntelliJ?

Question

IntelliJ spellchecker comes with only English and Arabic bundled (strange, I think it is made in east Europe, they didn't even bundle their language?).

My customer is German so all my code is mixed English (code)/German (interface) and I can't find a German dictionary for IntelliJ.

Solution 1

Current IDEA versions load dictionaries in UTF-8, you don't need to convert them to the platform encoding, ignore the iconv step below.

The dictionary can be produced using aspell for Unix/Mac OS X or under Cygwin. You need to have aspell and appropriate dictionary installed.

Here is the example for Russian dictionary I've used:

aspell --lang ru-yeyo dump master | aspell --lang ru expand | tr ' ' '\n' > russian.dic

For German it would be:

aspell --lang de_DE dump master | aspell --lang de_DE expand | tr ' ' '\n' > de.dic

Solution 2

I downloaded the ASCII spanish dictionary from this page, copied the included .dic file and it worked without any change: http://www.winedt.org/dict.html

There are many other languages.

OUTDATED: I get this info from this page (now this link is dead), who included additional details and format conversions that I didn't need: http://blog.novoj.net/2010/11/07/how-to-add-your-own-dictionary-to-intellij-idea-spellchecker/

Solution 3

This is based on all answers from here but including all the steps. I'm on Mac OS X (I think it will work on linux as well, except aspell installation) and I want the spanish dic

Only execute on terminal those lines that start with $ symbol

1. Install aspell:

   $ brew update
   $ brew install aspell
   

2. Download Aspell dic from their official repo

3. Extract tar.bz2 file

4. Go to extracted directory using terminal

   $ cd Downloads/aspell6-es-1.11-2
   

5. Compile and install dic.

   $ ./configure
   Finding Dictionary file location ... /usr/local/Cellar/aspell/0.60.6.1/lib/aspell-0.60
   Finding Data file location ... /usr/local/Cellar/aspell/0.60.6.1/lib/aspell-0.60
   $ make
   /usr/local/bin/prezip-bin -d < es.cwl | /usr/local/bin/aspell  --lang=es create master ./es.rws
   $ make install
   mkdir -p /usr/local/Cellar/aspell/0.60.6.1/lib/aspell-0.60/
   cp es.rws castellano.alias es.multi espanol.alias spanish.alias /usr/local/Cellar/aspell/0.60.6.1/lib/aspell-0.60/
   cd /usr/local/Cellar/aspell/0.60.6.1/lib/aspell-0.60/ && chmod 644 es.rws castellano.alias es.multi espanol.alias spanish.alias
   mkdir -p /usr/local/Cellar/aspell/0.60.6.1/lib/aspell-0.60/
   cp es.dat es_affix.dat /usr/local/Cellar/aspell/0.60.6.1/lib/aspell-0.60/
   cd /usr/local/Cellar/aspell/0.60.6.1/lib/aspell-0.60/ && chmod 644 es.dat es_affix.dat
   

6. Create the .dic file using:

   $ aspell -l es dump master | aspell -l es expand | tr ' ' '\n' > es.dic
   

Solution 4

Download a .dic from wherever you want(example). Then go to File > Settings > Spelling. There open the Dictionaries tap and add the path to the folder where you have saved the .dic in. It will auto-detect any .dic inside that folder. Apply.

Solution 5

Converting a Unicode dict to UTF-8 did the trick for me (sample for German / Linux computer):

NOTE: the converted german-dict can be downloaded here (<- already working).

If you need an other language please follow these steps:

1. (Just in case) If you have already linked .dic-files in IntelliJ, please remove them temporary by pressing the red minus in the settings.

2. Get your UNICODE(!) dictionary from here.

3. Now convert it to UTF-8, so IntelliJ will accept it:

   ~/Downloads/de_neu $ iconv -f UNICODE -t UTF-8 de_neu.dic > de_neu_utf8.dic

4. Go to File > Settings > type "dict" in the search and click Dictionaries > click the green plus and add the folder where "de_neu_utf8.dic" is stored.

5. Click OK, and you should be good to go. :)

thanks for the answer, I see that I got the right person :) I'm on mac and it looks like aspell is not included. In the end I took the dic from this plugin : plugins.intellij.net/plugin/?&id=1658 and converted the charset to macroman. But it looks like german is not a good language for dictionaries of this kind, many of my insurance-related words are unknown.

[CrazyCoder]

That dictionary is in UTF-8, could be a conversion or encoding issue. I'd recommend to wait for the next IDEA update with the new Spellchecker plug-in. Aspell for Mac can be installed separately: docs.moodle.org/en/Configuring_aspell_on_Mac_OS_X .

[CrazyCoder]

IDEA 9.0.2 EAP (build 94.585) should handle UTF-8 dictionaties fine, give it a try: confluence.jetbrains.net/display/IDEADEV/Maia+EAP.

[Grigory]

On Ubuntu 10.10 with IntellijIDEA 9.0.4 this command for getting the russian dict file with "yeyo" support: aspell --lang ru dump master | aspell --lang ru expand | tr ' ' '\n' > russian.dic

[Gabor Garami]

For some languages, the generated dictionary can be really big. E.g. I tried to generate dictionary for Hungarian language - and I stopped the process when the dictionary file reached the 3G. For smaller (but, of course, lesser useful) dictionary I created dictionary with aspell --lang hu dump master | cut -d/ -f1 > hungarian.dic. Smaller, but enough for some usages.

[Ricardo Martins]

and dont forget to change the encoding. It doesnt work if it's not utf-8

[Álvaro González]

Despite the name, the ASCII version contains Spanish characters (looks like ISO-8859-1/Windows-1252). Both versions ("ASCII" and "Unicode") seem to work fine as long as you re-encode them as UTF-8.

[Stefan Haberl]

this is the only answer that works for me in 2016 on a Mac. Use Editor > Spelling in IntelliJ's preferences to install the *.dic file.

[SalahAdDin]

Works this in Lunux's Operative Systems too?

[SalahAdDin]

Can we do the same using hunspell?

[chachan]

@SalahAdDin I didn't test it at the moment and I'm not using this IDE anymore :-/

[maxbellec]

the dictionnary I downloaded had utf-16 format. Worked fine after changing the encoding to utf-8

[Raven]

im running git bash on windows but it seems it does not support UNICODE iconv: conversion from UNICODE unsupported

[stian]

That link is dead - I think the correct one should be winedt.org/dict.html

[Ilya Serbis]

Hunspell is official plugin from the JetBrains. It is mentioned in the IntelliJ documentation (see Custom Dictionaries section). Unfortunately I was unable to make it work.

[Ilya Serbis]

Works for me (Russian)

[Rules]

See youtrack.jetbrains.com/issue/IDEA-210183 Yes it's extremely annoying that those ... hm RUSSIAN developers haven't implemented PROPER Russian support.. Please upvote for that issue..

[stackunderflow]

the language code 'de' did not work for me. For german, I had to use 'de_DE' (DE for Germany). There is also 'de_AT' and 'de_CH' (for Austria and Swiss).

[Gogowitsch]

The novoj.net link is dead. Please add the instructions to this answer here directly.

[Troglo]

The novoj.net is not required. Just download and copy the .dic file with your preferred language

[Christian Ulbrich]

Link with ftp://is wrong (or will simply download 0index.html); ftp.gnu.org/gnu/aspell/dict/0index.html is the overview page to select your language.

NB: path has to be set up to aspell command line in win10; the exe seems not be in path

[Philipp]

The command for german should be aspell --lang de_DE dump master | aspell --lang de expand | tr ' ' '\n' > de.dic ("--lang de" instead of "--lang de_DE" after the first pipe) -- Otherwise I am getting an error because /usr/lib/aspell/de_DE.dat does not exist (de.dat does exist).

[Oleg Abrazhaev]

this modification worked for me aspell --lang=de dump master | aspell --lang=de expand | tr ' ' '\n' > de.dic and I had to install de language before with sudo apt install aspell-de

[Mark Rotteveel]

@snakecharmerb PyCharm is basically a special version of IntelliJ, so things that work or exist for PyCharm, are very likely to exist for IntelliJ as well.

[Michael2]

In other versions of the plugin, it is Settings → Editor → Natural Languages
