Hi!
The readme.md file supplied with LanguageTool says:
Command-line version
To check plain text files from the command line, use
java -jar languagetool-commandline.jar -l xx <filename>
with
xx
being the code for your language, e.g.en-US
for American
English or justen
for English without spell checking activated.
And that’s all on the command line usage.
I use the above command to check a plain-text file containing a mere word list. The file size is about 1.8 Mib. LanguageTool fails throwing a java.lang.OutOfMemory error.
Suggestion: amend readme.md with something like the following:
If you receive a java.lang.OutOfMemory error, try increasing the Java
heap size as follows:java -XmxYYYYM -jar languagetool-commandline.jar -l xx <filename>
where YYYY is the size in megabytes. Example:
java -Xmx2048M -jar languagetool-commandline.jar -l xx <filename>
