Crosscompiling with Lazarus 1.8 on Linux Mint 18.3 | The Programming Works

Posted by jpluimers on 2020/01/08

As I will likely need this one day: [Archive.is / WayBack] Crosscompiling with Lazarus 1.8 on Linux Mint 18.3 | The Programming Works.

There are quite a few one-time manual setups to initially set this up, but after that it’s a piece of cake.

GitHub – Libaud/POLCLVCLISO: Pascal Object LCL and VCL ISO standards implementation for CodeTyphon, Delphi, Lazarus

Posted by jpluimers on 2020/01/02

For my link archive: GitHub – Libaud/POLCLVCLISO: Pascal Object LCL and VCL ISO standards implementation for CodeTyphon, Delphi, Lazarus

It implements these standards:

  • ISO standard 3166-1, 3166-2, 3166-3 implementation
    • (all part of the ISO 3166 – Wikipedia that “defines codes for the names of countries, dependent territories, special areas of geographical interest, and their principal subdivisions)”
  • ISO standard 4217 implementation
    • ISO 4217 – Wikipedia  “delineates currency designators, country codes (alpha and numeric)” where the country codes are the same as in ISO 3166
  • ITU E.164 standard implementation
    • E.164 – Wikipedia “E.164 defines a general format for international telephone numbers. Plan-conforming numbers are limited to a maximum of 15 digits, excluding the international call prefix.”

A library like this needs monitoring the standards changes, so hopefully Libaud will do that.

Some of my posts related to ISO 3166 are below.

Borland’s legendary development tools

Do you remember Turbo Languages from Borland? There are Pascal, C, Assembler, Basic, Prolog and many other products. Here there is link to directory containing original documentation of many these products:

http://bitsavers.informatik.uni-stuttgart.de/pdf/borland/

Did you work with some of them? Which one was your favorite?

Delphi ^A syntax: Documented, implied, or undocumented? – Stack Overflow

Posted by jpluimers on 2019/12/12

The syntax is documented. In the Turbo Pasal 3 documentation, i.e. the Z80 era.

Source my answer to [WayBack] Delphi ^A syntax: Documented, implied, or undocumented? – Stack Overflow (I have added some WayBack Internet Archive links below) as it is from the Turbo Pascal era where the caret was introduced to support control characters:

This is from long ago as an escape character to enable you to have consts for control characters in a more readable way.
const
  CtrlC = ^C;
begin
  Write(Ord(CtrlC));
end.

This defines a Char constant with value #3, then writes 3 in Borland Pascal 7, and I remember seeing it years before that too.

I just checked the Turbo Pascal 5.0 and Borland Pascal 7.0 languages guides, but could not find it, so it seems undocumented.

Edit: I do remember this was a Borland thing, and just [WayBack] checked: it is not part of the ISO Pascal standard (formerly this was ANSI Pascal Standard, thanks Sertac for noticing this).

It [WayBack] is documented in the Free Pascal documentation [WayBack].

SGI uses the backslash as escape character, as per their docs [WayBack].

More Edit: I found it [WayBack] documented in Delphi in a Nutshell and the [WayBack] Delphi Basics site.

Found it: Just found it on page 37 of the Turbo Pascal 3 Reference Manual [WayBack].

(Marco van de Voort found the Free Pascal documentation)

It in fact originates in the 1984 Turbo Pascal 1 edition, as per the [WayBack] Turbo_Pascal_Reference_Manual_Feb84.pdf:

Playing around with semantic typing in Oxygene: https://github.com/carlokok/semantictyping adding operators and methods to type aliases to store distinct types like distance, speed, acceleration while storing them as floats.

Check the repository linked; It essentially has types like Kelvin, Celsius ( https://github.com/carlokok/semantictyping/blob/master/SemanticTyping/Temperature.pas ), and Speed, Velocity, Acceleration ( https://github.com/carlokok/semantictyping/blob/master/SemanticTyping/Physics.pas ) using standard Oxygene features.
