Proofing Tool GUI: About Image
The most advanced open-source multiplatform Hunspell-based tool coded in PureBasic for editing the Dictionary/Thesaurus/Hyphenation/Autocorrect files of OpenOffice, LibreOffice, Firefox, Thunderbird, etc., provided they are in UTF-8-BOM format.

This program was originally developed to easily edit the synonyms of OpenOffice and LibreOffice.

I had this idea after asking the people managing the European Portuguese project, from Minho University, how to suggest synonyms since they were only adding dictionary entries.

I was told that they didn't know how to add synonyms, since the person in charge of that project left it long-ago (2006).

Later, I wanted to make my program compatible with Firefox and Thunderbird, after it became possible to edit dictionaries. I hoped that in the future, someone would use it in Thunderbird to fix the British speller, which was full of typos and missing words. Since no one volunteered, I took this task myself in 2013.

This is where my idea came from: develop something easy to use, since I tried some official tools for the tasks and I didn't understand anything about them nor how to use them.

Proofing Tool GUI is so intuitive that even a 6-year-old child can use it.



On
25.Aug.2013 I released a “forked” British speller V2.00 for OpenOffice/LibreOffice, Firefox, Thunderbird and SeaMonkey. So far, I have added 150 175+ words (as of V4.0.5).

Proofing Tool GUI: Why PureBasic Image
I use PureBasic for all my projects because
“I like it simple and powerful”.

This language is straightforward to use and powerful, it produces compact and very fast executables, and has multiplatform support.

It is
“Basic” only in the name and in the syntax.

I reached the conclusion that this is what I have been after all over these years.

Like
ImageLinus Torvalds, I use the “best tool for the job”, even if that includes proprietary software.

I use multiple tools for accomplishing something, both free and commercial, since all the features required aren't just in one app.

On
8.Nov.2023, I posted on the PureBasic forum, praising its power and ease of use but noting its lack of basic features long requested by users. I suggested an annual subscription to help Fred focus on major updates and reduce the need for excessive API coding for small features.
Imagehttps://www.purebasic.fr/english/viewtopic.php?t=82820

Fred replied:
“If you really a new feature for your software and you are not in mood to use API, you always can contact me in PM so we can discuss a pricing so I can prioritize it to implement it quickly (it needs to be useful for PB and fit in the command-set).”

On
5.Feb.2024, I reported bugs on the PureBasic forum. A user claimed 99.99% were useless due to being unreplicable. I responded that I always do my best, and Fred backed me up, confirming the reports were valid but mostly occurred in rare cases.
