Correct writing

These type of tool are really so needed while writing to ensure that your content are error free especially if you’re the type that can hardly spot out errors on your writing.
I am using this plugin as a sentence checker and improved my grammar as a writers to AceWriters.org writing service.
All Best!

It's depends on the language (or words used in answer to particular question). CorrectWriting use language to tokenize input - i.e. break answer down to the tokens - words, punctuation marks etc. That may not be always intuitive (cf. single apostrophe in English at the end of the word which can be a quote or a part of word). If the rules of tokenizing German (for you answers) are identical with English you can just use English in the question. If not, that will require some additional coding either from you or from us. I would expect problems with German letters that absent in English, I do not know about other details of German.
We can be contacted about developing support for other languages, thought considering other tasks we can't guarantee to do it fast. Thought if you are researcher, there are ways to motivate us to work faster under support of some language.

Is there a possibility to use another language istead of english (I do not mean C/C++ etc.) - german for example?

@Khac: Edit first line of string_pair.php (and other php files) from "<?" to "<?php"

Thank you. Now it works! I can set the penalty for missing token.
But, ...
not every token is as important as each of the others. Is it possible to add an indiviual missing penalty in the description token window? eg. separated by ~
for: for command~10%
( : bracket~5%
int : data type~20%
and so on
Sepp

Thanks, Sepp. Two penalties was really disappeared from the question editing screen during internal refactoring. A placed a new version there (2.6.1.) that should make them visible, please try it.
The button now called "show more".

Sorry, no such button. Some of green-asterisk-entries are visible, e.g. :
-Penalty for misplaced token
-Maximum percent of mistakes

Sepp, penalties with green asterisk are "advanced" and hidden by default.
did you see "Show advanced" or similar button on the form? Press it and you will see all settings.

In the manual picture there are 7 penalties to configure. I've installed current version and can find only 4 of them. Where are the missing penalties?
-missing token
-extra token
-absent token mistake hints
In this configuration a forgotten ")" in student's answer of for ( int i = 4; i <= 10; i++)
leads to 33% minus. This ist too strict.

There is some bug in `string_pair.php`. Look at the first line. It should be `<?php` not `<?`. It makes problems in strickt mode.

'It can found various mistakes in student's response' - very clever!

Oleg - Many thanks for sharing the correct writing question type. I was able to install without any issues. One concern I have is about the dependencies. This question type is listed as being for Moodle 2.4 and many of the dependencies do not show having a version for 2.4. We may want to be a little careful to ensure that everything seems to match up with respect to the versions (i.e. a 2.4 version of each plugin being available). I know you have a link to have them all together but if there begin to be differences between the versions that system may fall apart without carefully managing the branches. I presume that you want this plugin added to the PERL set. I will go ahead and approve this plugin and add it to the set. Please do not hesitate to let me know if there is anything I can do to be supportive of your efforts. Peace - Anthony
p.s. - Any objections to changing the URL for the source code to https://code.google.com/p/oasychev-moodle-plugins/source/browse/#hg%2Fquestion%2Ftype%2Fcorrectwriting which is more specific (rather than the more generic one that points to the root of the repository)?
