Tengo algunos emacs-fu razonables, y sé cómo usar el IDE de Flash Builder para trabajar en Flex/Actionscript, pero me gustaría pasar a usar Emacs para hacer la mayor parte de mi codificación en lugar del generador de flash. . Sin embargo, esto plantea algunos problemas, a saber, que no estoy seguro de cómo compilar mi proyecto de flexión desde la línea de comando fcsh-mode.¿Cómo puedo comenzar con Emacs + fcsh + Flex3?

He aquí un resumen de mi configuración:

  • Mis proyectos dependen de forma rutinaria en una combinación de archivos compilados de terceros SWC.
  • Utilizo algunas bibliotecas internas que guardo como Actionscript Library Projects en FB.
  • De vez en cuando vuelvo a compilar dependencias, pero probablemente pueda continuar haciendo esto en FB en el momento poco frecuente que sea necesario.
  • Cada proyecto de aplicación Flex consiste en una combinación de MXML y fuente de ActionScript.

Nunca he usado los compiladores de línea de comandos de esta manera, así que estoy un poco perplejo sobre cómo empezar. Sigo leyendo sobre compile 1 cuando la gente habla de fcsh en la red, pero eso solo me da fcsh: Target 1 not found, lo que significa que tengo que haber ejecutado la compilación 'correcta' de antemano. Pero ni un solo sitio web toca el encantamiento místico exacto que sería.

Por lo tanto, la pregunta básica aquí es: ¿Cuál es el conjunto mínimo completo de pasos que comienzan con la apertura de un actionscript o un archivo MXML para una compilación exitosa del archivo?

que no puedo comentar sobre Emacs + FCSH, pero tengo un poco de materia Flex en casa (es decir, sin IDE de Adobe), así que hacer mi compilación usando un proyecto de Ant ... si no otra cosa, esto podría ser una avenida para mirar. – weiji

Aquí está la cosa - fcsh no es realmente para proyectos de construcción, es para desarrollo incremental.

La mejor manera de descubrir fcsh es aprender primero cómo usar mxmlc y compc en la línea de comandos. La verbosidad necesaria para compilar su proyecto utilizando estas herramientas lo irritará en algún momento, por lo que querrá hacer una tarea de hormiga o similar, como weiji comentó anteriormente.

Por lo tanto, después de configurar su proyecto de hormiga, comenzará a darse cuenta de que, incluso si tiene todo bien configurado, la recompilación demora mucho más tiempo que cuando se utiliza Flex Builder. El motivo es la compilación incremental: FB no está recompilando todo, solo está recompilando el cierre del árbol de dependencias que cuelga de los archivos que ha cambiado.

Ingrese fcsh. Básicamente es una versión pirateada de mxmlc que incluye el mismo código de compilación incremental que utiliza FB. Almacena conjuntos de resultados de compilación parcial en conjuntos de resultados indexados, por lo que se refiere a la "compilación 1"; significa "reconstruir lo mismo que antes, pero solo recompilar las cosas cambiadas".

Ok, esa fue la parte de hecho, así que ahora en la opinión: no te molestes. Aunque fcsh puede acelerar en gran medida la recompilación de un gran árbol de fuentes esponjoso, la mejor respuesta es "no organices tu código de esa manera".Personalmente, creo que dividir con mayor cuidado su fuente para construir SWC o módulos, y configurar múltiples bibliotecas independientes compiladas por separado, con dependencias dependientes de la interfaz entre ellas es una ruta mucho mejor. Luego, cuando recompila, generalmente solo está reconstruyendo la biblioteca o reconstruyendo la aplicación, pero no todas las demás cosas también. Para mí, fcsh lleva demasiado tiempo "pensando" a mediados de compilación, mientras que una jerarquía de proyectos basada en bibliotecas es casi tan rápida y puedo ser más "tonto" sobre invocar la compilación M-x.

OH! Y no olvides "fdb". En su mayoría es compatible con gdb, por lo que M-x gdb en realidad funciona bastante bien, o al menos solía hacerlo cuando todavía estaba involucrado. :-D
