Voikkospell

Installation

m5w/corevoikko, a fork of corevoikko, supports apertium stream format.

To clone it, execute the following command:

git clone https://github.com/m5w/corevoikko.git corevoikko

First, install libvoikko's dependencies. Next, execute the following commands:

cd corevoikko/libvoikko
./configure
make
sudo make install

If you do not have root privileges or would like to specify where to install libvoikko, execute the following instead: (Otherwise, you are finished with installation.)

cd corevoikko/libvoikko
PREFIX="$HOME/install/corevoikko" # e.g.
./configure --prefix="$PREFIX"
make
make install

Finally, add your "$PREFIX" to your "$PATH" by appending the following lines to your .profile:

PREFIX="$HOME/install/corevoikko" # e.g.
if [ -d "$PREFIX" ]; then
        export PATH="$PREFIX/bin:$PATH"
fi

Using voikkospell with apertium Stream Format

Invoke voikkospell with --apertium-stream.

Unlike in normal voikkospell usage, each word does not need to be on its own line.

Examples

Trailing Newline

$ echo '' | voikkospell --apertium-stream
terminate called after throwing an instance of 'Apertium::ApertiumStream::Unexpe
ctedReservedCharacter'
  what():  1:1: unexpected '\n', '\n' expected to follow '['


^
Aborted

For this reason, when piping text directly to voikkospell --apertium-stream, use echo -n. It is not necessary to do this when piping through tools such as apertium-deshtml, which encapsulate all newlines in superblanks.

One could also escape the newline:

$ echo '\' | voikkospell --apertium-stream

Unanalysed Word

$ echo -n '^a/*a$' | voikkospell --apertium-stream
W: a

Analysed Words

One Tag

$ echo -n '^b/b<A>$' | voikkospell --apertium-stream
W: b

More Than One Tag

$ echo -n '^c/c<B><C>$' | voikkospell --apertium-stream
W: c

Ambiguous Word

$ echo -n '^d/d<D>/d<E><F>$' | voikkospell --apertium-stream
W: d

Multiwords

One Word with Inner Inflection

$ echo -n '^e f/e<G># f/e<H><I># f$' | voikkospell --apertium-stream
W: e f

More Than One Word

Without Inner Inflection

$ echo -n 'gh/g<J>+h<K><L>/g<M>+h<N>$' | voikkospell --apertium-stream
W: gh

With Inner Inflection

$ echo -n '^i jk/i<O># j+k<P><Q>/i<R># j+k<S>$ ^lm n/l<T>+m<U># n/l<V>+m<W># n$' | \
voikkospell --apertium-stream
W: i jk
W: lm n

Reserved Characters

\, ^, /, <, >, and $ are reserved.

\

$ echo -n '\' | voikkospell --apertium-stream
terminate called after throwing an instance of 'Apertium::ApertiumStream::Unexpe
ctedEndOfFile'
  what():  1:1: unexpected end-of-file following '\', end-of-file expected to fo
llow ']' or '$'

$ echo -n '/' | voikkospell --apertium-stream

ately, or to follow '^' or '#' not immediately

$ echo  -n '<' | voikkospell --apertium-stream

$ echo -n '>' | voikkospell --apertium-stream

  what():  1:1: unexpected '>', '>' expected to follow '[' or to follow '<' not 
immediately

$

$ echo -n '$' | voikkospell --apertium-stream
terminate called after throwing an instance of 'Apertium::ApertiumStream::Unexpe
ctedReservedCharacter'
  what():  1:1: unexpected '$', '$' expected to follow '[', to follow '>' immedi
ately, or to follow '*' or '#' not immediately
$

Aborted

Escape

To avoid these errors, escape all reserved characters.

$ echo -n '\\\^\/\<\>\$' | voikkospell --apertium-stream

Superblank

Alternatively, one can enclose reserved characters in superblanks.

$ echo -n '[^/<>$]' | voikkospell --apertium-stream

However, \ must be escaped.

$ echo -n '[\]' | voikkospell --apertium-stream
terminate called after throwing an instance of 'Apertium::ApertiumStream::Unexpe
ctedEndOfFile'
  what():  1:3: unexpected end-of-file following '[', end-of-file expected to fo
llow ']' or '$'
[\]

Putting It All Together

Let's spellcheck a webpage!

voikkospell's webpage has a mixture of English and Finnish words, so we should get a good mixture of correct and incorrect spellings.

Since voikkospell only checks spelling, it doesn't matter which analyser we use. In this example, I use apertium-en-ca's English analyser.

$ curl -s http://voikko.puimula.org/ | apertium-deshtml | lt-proc ~/svn.code.sf.net/p/apertium/svn/trunk/apertium-en-ca/en-ca.automorf.bin | voikkospell --apertium-stream
