Foro - Perl en Español

por **pablgonz** » 2010-12-14 17:05 @753

Hola, hace un tiempo me uní a este foro para solucionar un pequeño problema con un script que uso en TeX. Ahora tengo otro problema, deseo añadir la opción -h al script pst2pdf, es decir, comentar la línea 363 y con Getopt::Long; y Pod::Usage; crear la ayuda de dicho script, pero, todos mis intentos han fracasado, el script solo me dice que tengo un error en la línea 77 (arroja Unknow option -h); además, me crea el fichero -h-pdf.tex. O -loquesea-pdf.tex.
Lo he intentado de varias maneras, pero el script es un tanto complejo para mi, logro crear la ayuda en otros ficheros y script pequeños, pero no en éste.
Agradezco de antemano por su ayuda.

El problema está en la línea 48. Ahí se accede de forma directa al valor de $ARGV[0], que guarda el primer argumento.

El programa espera, como primer argumento, el nombre del fichero TeX a procesar. Siempre.

Así que si llamas al programa con un argumento '-h', ese será el nombre del fichero.

Yo lo que haría sería poner la línea 54 en lugar de la 45, y agregar a GetOptions() el procesamiento de la opción 'h'.

Lo intenté tal cual me escribes, pero al correr perl pst2pdf me arroja fileparse(): need a valid pathname. Gracias por tu pronta respuesta, seguiré leyendo e intentando.

Claro que da error: hay que modificar el programa para que tenga en cuenta el caso de que el usuario lo haya ejecutado sin darle ningún fichero como argumento.

El procedimiento, según se cuenta en la sección Mixing command line option with other arguments del módulo Getopt::Long es que hay que llamar a GetOptions nada más empezar el programa, y luego, lo que quede en @ARGV, serán el resto de argumentos que el programa necesitará.

En tu caso, se trata del nombre del fichero. PERO, naturalmente, estás pensando de pasarlo de obligatorio (como está ahora) a opcional (si el usuario llama al programa con '-h' es que quiere ver la ayuda del programa, por lo que no pasará ningún fichero).

Ese caso lo tienes que contemplar en el código.

Coloreado en 0.015 segundos,  usando GeSHi 1.0.8.4

Y como dice explorer, no verifica si 'existe' el fichero antes de abrirlo, por eso crea los 'LOGs' inutilmente, agregar Pod::Usage es similar a lo que hice, puedes mejorarlo ;-)

PD: las caritas 'smiles' y los tabs se traducen aún usando etiquetas perl code, queda feito pero se entiende.

por **explorer** » 2010-12-15 13:26 @601

Las caritas sonrientes se pueden deshabilitar debajo de la caja de edición de texto de cada mensaje, en la opción que se llama "Deshabilitar emoticonos".

Y los tabuladores se arreglan reduciéndolos o cambiándolos por espacios...
