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 *.*  :crazy:  :o  and much more

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
http://sourceforge.net/p/pseint/code/ci/302b3dd55782df9400af44104bd5ffe0db1fc27a/tree/pseint/new_evaluar.cpp#l14

file: new_evaluar.cpp   

Code: [Select]
bool PalabraReservada(const string &str) {
// Comprobar que no sea palabra reservada
if (word_operators && (str=="Y" || str=="O" || str=="NO" || str=="MOD"))
return true;
if (str=="LEER" || str=="ESCRIBIR" || str=="MIENTRAS" || str=="HACER" || str=="SEGUN" || str=="VERDADERO" || str=="FALSO" || str=="PARA")
return true;
if (str=="REPETIR" || str=="SI" || str=="SINO" || str=="ENTONCES" ||   str=="DIMENSION" || str=="PROCESO")
return true;
if (str=="FINSI" ||  str=="FINPARA" || str=="FINSEGUN" || str=="FINPROCESO" || str=="FINMIENTRAS" ||  str=="HASTA" || str=="DEFINIR" || str=="COMO")
return true;
if (str=="FIN" ||  str=="IMPRIMIR" || str=="BORRAR" || str=="LIMPIAR" || str=="PANTALLA" ||  str=="BORRARPANTALLA" || str=="LIMPIARPANTALLA")
return true;
if (str=="SIN" || str=="BAJAR" || str=="SINBAJAR" || str=="SALTAR" || str=="SINSALTAR")
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=="REPEAT" || str=="IF" || str=="ELSE" || str=="THEN" ||   str=="DIMENSION" || str=="PROCESS")
return true;
if (str=="IFEND" ||  str=="FOREND" || str=="SWITCHEND" || str=="PROCESSEND" || str=="WHILEEND" ||  str=="TO" || str=="DEFINE" || str=="AS")
return true;
if (str=="END" ||  str=="PRINT" || str=="DELETE" || str=="CLEAR" || str=="CLEANSCREEN" ||  str=="SCREEN" || str=="DELSCREEN ")
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 :)

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?

Here are two new parts:
Spoiler For Documents and Manuals:
Documents and Manuals:
For the documentation of the newest versions, consult the following sections of the site:
   Characteristics and Functions
   PseudoCode
   Examples
   Screen Captures
More details can be found in the in-program help.

Other related links:
   GPL licence under which the software's distributed.
   Changelog to see what's new in each version.
   List of known bugs: errors known to be present in the latest available version.
   Timeline: a summary of the major milestones in the life of this project.   
   Cucarachas Racing is a blog where I publish information about my projects (among which is PSeInt) in a somewhat disorganized manner, sharing both technical information (about programming) as well as information directed towards the end user (about functions and decisions on design).

About...
PSeInt - copyleft 2003-2013 (by Pablo Novara - zaskar_84<arroba>yahoo.com.ar)

Special thanks to those who helped in the revival of this project in its early stages (Román Gelbort, Adrián Staffolani, Patricia Chechele, Horacio Loyarte, Joaquín Duo, et al), and many other professors and students who sent in daily error reports and suggestions online or by e-mail.
Spoiler For Characteristics and Functions:
What purpose does PSeInt serve?
   PSeInt was designed to help students who are just getting started in creating computer programs and/or algorithms. Pseudocode is generally used as one's first contact to introduce basic concepts such as the use of control structures, expressions, variables, etc., without having to deal with the particularities in the syntax of a real language. This software attempts to facilitate the task of writing algorithms in this pseudolanguage by offering a wide array of help and assistance and providing aditional tools to help locate errors and understand the logic behind the algorithms.
   
Characteristics and Functions of PSeInt:

   Editing tools to write algorithms in pseudocode (in Spanish)
      Autocompletion
      Pop-up Help Dialogs
      Command Templates
      Syntax Highlighting
      Smart/Autoindent
   Generation and editing of the algorithm's flow charts
   Simultaneous editing of multiple algorithms
   Pseudocode language is configurable
      Offers predefined configuration profiles for many institutions
   Can interpret (ie. execute) the algorithms you write
      Step-by-step execution of an algorithm, controlling speed and monitoring variables and expressions
      Can automatically prepare a table listing the state of variables throughout the execution of your program
   Determines and clearly marks syntax errors as you type and during execution
   Allows the conversion of the algorithm to C++
   Offers an integrated help system about the psuedocode and how to use the program
      Includes a set of examples with differing difficulty levels
   Multiplatform (tested on Microsoft Windows, GNU/Linux, and Mac OS X)
   100% free (GPL license)

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 :P) 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 :)
