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.
