How to define aspell word delimiters?

Question

Aspell considers words with underscores or dashes as two, e.g. cloud-based is spell checked as "cloud" and "based". Is there any way to specify the word delimiters so as to exclude dash and underscore?

Answer 1

If I understand the question correctly, Aspell cannot do exactly what you want (up to my knowledge). This has to do with conditional compound word treatment, which is on the Aspells TODO list.

On the same list it is mentioned that Hunspell does a better job with compound words, so it might be a viable alternative if you're not bound to Aspell. OpenOffice uses Hunspell for spellchecking, so it is easy to find out whether it fits your requirements. It does, at least, work for the "cloud-based" example, and does NOT consider all hyphenated words unconditional compounds, i.e. "based-cloud" would not be considered a spelling error.

Answer 2

Aspell is unable to do what you want it to do at this point. The interface it uses for handling word with symbols in them is not sophisticated enough to handle such a case at this time. More information on this is listed here.

Sorry that this cannot be solved up to this point, unless you want to implement your own interface. I would recommend using Hunspell as Mikhail suggested.
