Lexer PureBasic

[skarsgal]

Hi Alexey,
I ask you to create the lexer for PureBasic (a very powerful and advanced basic language).
I have found the source of this syntax highlighting on Andrè Simon's website:

Details:
- website: http://andre-simon.de/
- download area: http://andre-simon.de/zip/download.php
- download archive 'highlight-4.14-x64.zip': http://andre-simon.de/zip/highlight-4.14-x64.zip (copy this link in your browser and confirm)
- in this archive browse inside directory: 'langDefs'
- extract the file: purebasic.lang (ascii)

This syntax highlighting (created by Tristano Ajmone) is for PureBasic v5.00 -- 5.61, while the current version of Purebasic is 6.12.0 of 18/09/2024.

Do You can create a lexer for PureBasic?
Thanks

Before I do, I am interested - how popular is it? ie how many users, how many projects on language?
(e.g. FreePascal - many users, and many small projects, and big forum)

And 2nd: give me 1-2 sample source code repos with some projects, so I can test lexer.

Unfortunately it is not very widespread even though it is a programming language that has been in development for 20 years.
The reason is that the compiler is a paid program that costs € 79.00.
A very important resource is the forum, where you can find an answer to (almost) every question.
1. PureBasic Forum: https://www.purebasic.fr/english/
2. Forum total members: n. 6,461
3. Forum total posts: n. 576,233

Note_1
this samples have 1 or 2 ascii files:
- .pb (PurerBasic)
- .pbi (PureBasic Include) it is a file called by .pb (It is an optional file)

Note_2
if you wish, you can download the Demo version of the compiler:
- fully functional
- compilation limited to about 1,000 lines of code
download link: https://www.purebasic.com/download/Pure ... mo_x64.exe
--> this installer is compiled with Inno Setup v6.1.0
--> extract with InnoUnpacker by Jürgen Rathlev https://www.rathlev-home.de/index-e.htm ... tml#unpack
--> the compiler is Portable via command line flag

it is not widespread, and SublimeText syntax file has only 350 downloads.
https://packagecontrol.io/packages/PureBasic
(for popular langs, Sublime files have 3K+ downloads.)
can you read lexer tutorials
https://github.com/Alexey-T/CudaText/tr ... /tutorials
and construct lexer from scratch, please?

[main Alexey]

wait, I can build the _base of lexer_ (unfinished lexer). then we will see how to continue.

[main Alexey]

draft version is made.
https://github.com/Alexey-T/CudaText-le ... /PureBasic
copy these files (except INF file) into subfolder data/lexlib near other LCF files.

I did not read docs yet. so many issues are possible. let's test and find them all. I can continue this work.

- keywords were found by my reading of sample projects. I don't know the full list of keywords, check them.
- symbol $ - how to highlight it? as part of previous token? e.g. here: #AB$, Ab$.
- I added only blocks folding found in samples. check all possible blocks foldings.

It is possible 'translate' the lexer PureBasic from Sublime Text repository ?

- keywords were found by my reading of sample projects. I don't know the full list of keywords, check them.

There is an online resource:
see on Pure Basic Reference Manual at https://www.purebasic.com/documentation/
There are two paragraph:
- Basic Keywords
- Advanced Keyworks
with all keywords and usage samples

- symbol $ - how to highlight it? as part of previous token? e.g. here: #AB$, Ab$.

See on : Pure Basic Reference Manual --> General Syntax Rules at https://www.purebasic.com/documentation ... rules.html

- I added only blocks folding found in samples. check all possible blocks, which are not folded.

I'm sorry, I don't know how to do it.

I updated lexer on the same URL. added all keywords (also from Sublime syntax file). fixed ~-strings. fixed $ as last char of names. added float numbers like 1.2e-3.

[main Alexey]

updated again. added highlight of labels (Name: but not Name::Name). added folding for 'DataSection'.

Thank a lot for this PureBasic lexer.
