Proofing Tool GUI — About:
An open-source multiplatform advanced linguistic tool coded in PureBasic for editing the Dictionary/Thesaurus/Hyphenation/Autocorrect files of OpenOffice, LibreOffice, Firefox, Thunderbird and SeaMonkey, provided they are in UTF-8 format.

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

I had this idea after asking the persons in charge of the pt_PT project, from Minho University in Portugal, what I should do to suggest synonyms since only suggested words for the Portuguese speller were added.

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 it compatible with Firefox and Thunderbird, after it became possible to edit dictionaries. I hoped that in the future, someone would use it in Thunderbird and fix the en_GB 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 on them, not even how to use them.

My tool is so intuitive that even a child can use it.

25.Aug.2013 I released a “forked” en_GB speller V2.00. The speller has been made available to OpenOffice/LibreOffice, Firefox, Thunderbird and SeaMonkey. So far, I have added 132 829+ words (as of V3.1.3).

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.

Proofing Tool GUI — Known issues on Linux:
PTG V3.0 build 197 (PureBasic 6.00 beta 8) is now compatible with GTK 3.24.33: Ubuntu 22.04 LTS.

PTG V3.0 build 196 (PureBasic 6.00 beta 6)
and below breaks with GTK 3.24.33 which affects Ubuntu 22.04 LTS.

PTG V3.0 build 195 (PureBasic 6.00 beta 1)
requires GTK 3.20 and Ubuntu 20.04 LTS or above.

PTG V3.0 build 146
(PureBasic 5.70) requires GTK3 and Ubuntu 18.04 LTS or above.

PTG V3.0 build 120
(PureBasic 5.62) went back to GTK2 due to a serious GUI issue in Ubuntu 17.10.

PTG V3.0 build 90
fixed the performance issue. I use dynamic arrays to store the words instead of placing the whole list in ListIconGadgets, and I show the entries 13 (customisable) words at a time. Most operations are ultrafast with the new code.
