auto-completiondictionariestexstudio
Is it somehow possible to extend TexStudio to use dictionary words in autocompletion?
For example, when I type "som", I want the autocompletion list to show me all words from the dictionary starting with "som". I know TexStudio uses autocompletion for words that already appear in the same document.
I've tried to create a .CWL file, but apparently it is only for commands and plain words are not supported.
Hunspell dictionaries (.dic and .aff) are more complex than just word lists (i.e. it contains information of possible affixes). Therefore, a proper entry cannot be generated from a single word.
The solution in TexStudio is to store additional words in an ignore word list (.ign) next to the dictionary. This list can be populated via Context Menu -> always ignore or via the Always Ingore button in the spell checking dialog.
Note: On Windows 7 the default dictionaries are in
C:\Program Files (x86)\TeXstudio\dictionaries\
Windows 7 prevents writing to the program files directory.It redirects the writes to User dictionaries, which are in
C:\Users\<User>\AppData\Local\VirtualStore\Program Files (x86)\TeXstudio\dictionaries
You may find the .ign files there.
For that, you will have to make use of a custom .cwl file (which, afaik, requires a recent version of TeXstudio).
Create a file, let's say mycwl.cwl, in either %appdata%\texstudio\completion\user or .config/texstudio/completion/user according to your system.
In it, place the following line:
\alternative{label}#r
and save it. Technically, you can put anything meaningful in the argument, but some terms are reserved and have special meaning. And, as you wish TeXstudio to recognize a label there, you require one of those, namely label. The comment at the end of the line tells TeXstudio what kind of command yours is. #r stands for this command declares a reference like "\ref{key}". For further commands, just add a new line to your mycwl.cwl.
Then, in TeXstudio, go to Options -> Configure TeXstudio -> Completion and check mycwl.cwl on the list (crucial). And that's about it.
For more details on customizing autocompletion with cwl files, check the TeXstudio manual, section "4.13 Description of the cwl format".
A tip: If the manual seems complicated, and you'd like to emulate the behavior of some command's autocompletion you like, you might want to download the sourcecode tarball at http://texstudio.sourceforge.net/, unpack it and look at the built-in cwl files in the "completion" folder. From there, you can proceed by means of examples of your commands of interest.

TeXstudio only has a command completion (based on the cwl files). There is no word completion (also not for words that already appear in the document).
You can however achieve something similar for fixed word lists by scripting.
