Proofing Tool GUI: About
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 143 122+ words (as of V4.0.1).


NOTICE:
I have been publicly criticised for my GB dictionary, even in front of other developers. They only point out flaws instead of suggesting new words or corrections. There are millions of words, and I can't manage them all alone.

This project is very serious. I spend hundreds of EUR every year on web hosting, domains, and a premium Oxford Dictionaries account so that everyone can enjoy quality work for free.

I am a disabled person and open-source is almost all I have left in life.

Proofing Tool GUI: Why PureBasic
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
Linus 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.
https://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.

Proofing Tool GUI: Release Notes
V4.0 beta is very stable, and it is the latest release.

I rushed into releasing the unfinished PTG 4.0 build 300 because suicidal thoughts were crossing my mind.
Schizophrenia is a silent illness, you can look at someone with it and see nothing abnormal, but deep inside the person is all corroded.


V4.0 build 300: Major GUI/UX improvements and bug fixes.

On build 300:
— Major release.

Proofing Tool GUI: Known issues on Windows/Linux⠀
The latest versions of PTG V4.0 (Windows) require at least Windows 10.

The latest versions of PTG V4.0 (Linux)
require at least GTK 4.00 and Ubuntu 24.04 LTS.

There are some glitches between the Windows and Linux version caused by PureBasic 6.21.
