Hello, I invite ta check this new tool written in C++ (pseudo-code interpreter), Volunteers wanted to translate it to English and other languages

PSeInt is a tool for learning logic programming oriented to students with no experience in computer programming. Using a pseudo-language, intuitive, can begin to understand basic concepts and principles of a computer algorithm, Also allows export to C++, create edit and export to flow chart, step to step running, and CODING and EXECUTION in REAL TIME

and much more

That's pretty nice. I hope you make an English version though.

can also be used to export code to TI-BASIC

Could you post export_TI_Basic.h ? The code excerpts that you've posted so far are clearly C++ (string, namespace, passing arguments by reference), but GCC4TI doesn't support C++.

Here's the little intro text:
PSeInt is a tool to learn logic programming, geared towards students without any prior experience in logic programming. Through the use of a limited, simple, and intuitive pseudo-language (in Spanish), one can begin to learn and understand the basic fundamental concepts of a computer algorithm. Originally conceived as the final project for the Programming I course of the Computer Engineering degree in the Faculty of Engineering and Water Sciences at the National University of the Littoral, it is actually a pseudocode interpreter based on the contents of the Fundamentals of Programming class of the same degree.

Sólo una cosa, no entiendo muy bien qué significa aquí cátedra, supongo que no es tan importante pero yo siempre pensé que una "cátedra" era como el trabajo de un "catedrático", pero me parece que aquí no tiene mucho sentido...

I can start translating the documentation, if you want

>> Sólo una cosa, no entiendo muy bien qué significa aquí cátedra
Catedra también significa Curso o Asignatura; cátedra de Fundamentos de Programación == Curso de Fundamentos de Programación

>>I can start translating the documentation, if you want

English:
Currently PSeInt only supports pseudocode in Spanish

To create a version in English (pseudocode in English or another language) is required to made a parallel program current development PSeInt_ENG

Spanish:
Actualmente PSeint solo soporta PSeudoCode en Spanish
Para crear una versión en English se requiere crear un programa paralelo al actual desarrollo

Example: Spanish

		return true;
	return false;
}

ENG: The same code above with keywords in English
SPN: El mismo código anterior en English

file: new_eval.cpp

Code: [Select]

bool KeyWord(const string &str) {
	// Check that there is not keyword
	if (word_operators && (str=="AND" || str=="OR" || str=="NOT" || str=="MODULE"))
		return true;
	if (str=="READ" || str=="WRITE" || str=="WHILE" || str=="DO" || str=="SWITCH" || str=="TRUE" || str=="FALSE" || str=="FOR")

		return true;
	if (str=="WITHOUT" || str=="DOWN" || str==" WITHOUT DOWN" || str=="SKIP" || str=="WITHOUTSKIP")
		return true;
	return false;
}

...

SPN:
Programas en pseudocode hay muchos en la internet, pero lo valioso de este software es que mientras se codifica o se re-edita se ejecuta sin necesidad de volver a lanzar el programa desde el inicio, además genera un diagrama de flujo editable. Así que vale la pena llevar este software a INGLES u otro lenguaje.

Se requiere de muchas personas, para traducir el código fuente, la interface etc, además que es compilable con Win,LINUX y MAC

Otra ayuda seria, crear extensiones para exportar a VisualBasic, JAVA, LUA, TI-BASIC, etc, por que actualmente solo exporta a C++

Thanks

By writing the code differently, there could be a single source code which handles multiple languages, through either simple collections of defines activated one at a time (easy, that's what multiple TI-Chess Team programs do) and multiple binaries which speak a single language, or using time-proven solutions such as gettext's libraries (that's what libti*/gfm/tilp and tiemu do). Multiple independent but similar source files are a maintenance nightmare.

If the authors want to have the best chances of attracting contributors and translators, the code base (function and variable names, comments) should be entirely written in English

DJ Omnimaga · « **Reply #9 on:** April 03, 2013, 03:06:43 pm »

Nice. Can this tool be used to learn languages such as Z80 assembly without a single high-level language knowledge first or would it be better than someone still learns another language first with this before switching to ASM?

chickendude · « **Reply #10 on:** April 04, 2013, 03:13:35 am »

Here are two new parts:

Spoiler For Documents and Manuals:

Spoiler For Characteristics and Functions:

To translate some of the other parts, it might be worthwhile to translate some of the instructions first, for example AZAR could become RAND or RANDOM, SENO (a funny name

) could become SINE, etc.

EDIT: And @DJ_O: i still don't think it's really necessary to study another language first before starting ASM (i never did and still haven't

), though i don't see how this would help you learn z80 assembly... I'd be interested to hear about that though
