text-input-directive

Documentación en español para la librería text-input-directive.

Propósito
--------
La librería exporta la directiva CbmTextInputDirective (standalone) que facilita el control de entradas de texto en formularios, aplicando transformaciones, validaciones en tiempo real y reglas de pegado. Es útil para normalizar el comportamiento de inputs de texto en distintas pantallas.

Qué exporta
------------
- CbmTextInputDirective — directiva standalone que se aplica a elementos o
</code>.
<br />- <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">TCbmTextInputTransform</code> — tipo <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">'uppercase' | 'lowercase' | 'capitalize'</code>.
<br />
<br />Inputs / parámetros
<br />-------------------
<br />La directiva declara los siguientes inputs (usando la función <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">input()</code> de Angular):
<br />
<br />- <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">maxTextLength?: number</code> — longitud máxima total del texto. Si se supera, se evita la inserción.
<br />- <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">maxWordLength?: number</code> — longitud máxima permitida por palabra; palabras largas se truncan o se bloquean en pegado.
<br />- <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">transform?: 'uppercase' | 'lowercase' | 'capitalize'</code> — transformación que se aplica en cada input.
<br />- <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">pattern?: string | RegExp</code> — expresión regular para validar caracteres permitidos; si la entrada no cumple, se previene la acción.
<br />
<br />Comportamiento principal
<br />------------------------
<br />- onKeyDown: valida la tecla pulsada contra <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">pattern</code>, controla longitud total y longitud de palabra actual, y permite teclas especiales (Backspace, flechas, Ctrl+C/V/X).
<br />- onPaste: valida el texto pegado contra <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">pattern</code>, <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">maxTextLength</code> y <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">maxWordLength</code>. Publica mensajes de error usando <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">PubSub.publish('alert', { ... })</code> cuando la validación falla.
<br />- onInput: aplica la <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">transform</code> configurada y trunca palabras que exceden <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">maxWordLength</code>.
<br />
<br />Ejemplo de uso
<br />--------------
<br />En template:
<br />
<br />``<code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">html
<br /><input
<br />  cbmTextInput
<br />  [maxTextLength]="100"
<br />  [maxWordLength]="20"
<br />  [transform]="'capitalize'"
<br />  [pattern]="'^[A-Za-z0-9 ]*$'"
<br />/>
<br /></code>`<code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">
<br />
<br />Notas técnicas
<br />--------------
<br />- La directiva usa </code>PubSub<code class="bg-muted px-1 py-0.5 rounded text-sm font-mono"> (paquete </code>pubsub-js<code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">) para publicar alertas en el evento </code>paste<code class="bg-muted px-1 py-0.5 rounded text-sm font-mono"> cuando el contenido pegado no cumple las reglas. Asegúrate de tener un manejador global para </code>alert<code class="bg-muted px-1 py-0.5 rounded text-sm font-mono"> o sustituir esa lógica según tus necesidades.
<br />- </code>input()<code class="bg-muted px-1 py-0.5 rounded text-sm font-mono"> es usado para declarar inputs de forma compacta; la directiva lee estos valores en tiempo de ejecución.
<br />- Se permiten operaciones de portapapeles con Ctrl/C/V/X y navegación con flechas.
<br />
<br />Testing
<br />-------
<br />El proyecto incluye una spec base </code>text-input.directive.spec.ts<code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">. Ejecuta las pruebas con:
<br />
<br /></code>`<code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">powershell
<br />ng test
<br /></code>``
<br />
<br />Contribuciones y mejoras sugeridas
<br />---------------------------------
<br />- Añadir soporte para reglas de validación más complejas (por ejemplo bloqueo por blacklist).
<br />- Hacer la publicación de alertas configurable (callback o servicio de mensajes en vez de PubSub directo).

`text-input-directive`.\r\n\r\nPropósito\r\n--------\r\nLa librería exporta la directiva `CbmTextInputDirective` (standalone) que facilita el control de entradas de texto en formularios, aplicando transformaciones, validaciones en tiempo real y reglas de pegado. Es útil para normalizar el comportamiento de inputs de texto en distintas pantallas.\r\n\r\nQué exporta\r\n------------\r\n- `CbmTextInputDirective` — directiva standalone que se aplica a elementos `\u003cinput\u003e` o `\u003ctextarea\u003e`.\r\n- `TCbmTextInputTransform` — tipo `'uppercase' | 'lowercase' | 'capitalize'`.\r\n\r\nInputs / parámetros\r\n-------------------\r\nLa directiva declara los siguientes inputs (usando la función `input()` de Angular):\r\n\r\n- `maxTextLength?: number` — longitud máxima total del texto. Si se supera, se evita la inserción.\r\n- `maxWordLength?: number` — longitud máxima permitida por palabra; palabras largas se truncan o se bloquean en pegado.\r\n- `transform?: 'uppercase' | 'lowercase' | 'capitalize'` — transformación que se aplica en cada input.\r\n- `pattern?: string | RegExp` — expresión regular para validar caracteres permitidos; si la entrada no cumple, se previene la acción.\r\n\r\nComportamiento principal\r\n------------------------\r\n- onKeyDown: valida la tecla pulsada contra `pattern`, controla longitud total y longitud de palabra actual, y permite teclas especiales (Backspace, flechas, Ctrl+C/V/X).\r\n- onPaste: valida el texto pegado contra `pattern`, `maxTextLength` y `maxWordLength`. Publica mensajes de error usando `PubSub.publish('alert', { ... })` cuando la validación falla.\r\n- onInput: aplica la `transform` configurada y trunca palabras que exceden `maxWordLength`.\r\n\r\nEjemplo de uso\r\n--------------\r\nEn template:\r\n\r\n```html\r\n\u003cinput\r\n  cbmTextInput\r\n  [maxTextLength]=\"100\"\r\n  [maxWordLength]=\"20\"\r\n  [transform]=\"'capitalize'\"\r\n  [pattern]=\"'^[A-Za-z0-9 ]*$'\"\r\n/\u003e\r\n```\r\n\r\nNotas técnicas\r\n--------------\r\n- La directiva usa `PubSub` (paquete `pubsub-js`) para publicar alertas en el evento `paste` cuando el contenido pegado no cumple las reglas. Asegúrate de tener un manejador global para `alert` o sustituir esa lógica según tus necesidades.\r\n- `input()` es usado para declarar inputs de forma compacta; la directiva lee estos valores en tiempo de ejecución.\r\n- Se permiten operaciones de portapapeles con Ctrl/C/V/X y navegación con flechas.\r\n\r\nTesting\r\n-------\r\nEl proyecto incluye una spec base `text-input.directive.spec.ts`. Ejecuta las pruebas con:\r\n\r\n```powershell\r\nng test\r\n```\r\n\r\nContribuciones y mejoras sugeridas\r\n---------------------------------\r\n- Añadir soporte para reglas de validación más complejas (por ejemplo bloqueo por blacklist).\r\n- Hacer la publicación de alertas configurable (callback o servicio de mensajes en vez de PubSub directo).\r\n\r\nLicencia\r\n--------\r\nConsulta la licencia del repositorio principal.\r\n"])</script><script>self.__next_f.push([1,"1a:[\"$\",\"$L1b\",null,{\"defaultValue\":\"readme\",\"className\":\"w-full\",\"children\":[[\"$\",\"$L1c\",null,{\"children\":[[\"$\",\"$L1d\",null,{\"value\":\"readme\",\"children\":\"Readme\"}],[\"$\",\"$L1d\",null,{\"value\":\"dependencies\",\"children\":[\"Dependencies\",[\"$\",\"span\",null,{\"className\":\"ml-1.5

<br /><h1 class="text-2xl font-bold mt-6 mb-4">text-input-directive</h1>
<br />
<br />Documentación en español para la librería <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">text-input-directive</code>.
<br />
<br />Propósito
<br />--------
<br />La librería exporta la directiva <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">CbmTextInputDirective</code> (standalone) que facilita el control de entradas de texto en formularios, aplicando transformaciones, validaciones en tiempo real y reglas de pegado. Es útil para normalizar el comportamiento de inputs de texto en distintas pantallas.
<br />
<br />Qué exporta
<br />------------
<br />- <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">CbmTextInputDirective</code> — directiva standalone que se aplica a elementos <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono"><input></code> o <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono"><textarea></code>.
<br />- <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">TCbmTextInputTransform</code> — tipo <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">'uppercase' | 'lowercase' | 'capitalize'</code>.
<br />
<br />Inputs / parámetros
<br />-------------------
<br />La directiva declara los siguientes inputs (usando la función <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">input()</code> de Angular):
<br />
<br />- <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">maxTextLength?: number</code> — longitud máxima total del texto. Si se supera, se evita la inserción.
<br />- <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">maxWordLength?: number</code> — longitud máxima permitida por palabra; palabras largas se truncan o se bloquean en pegado.
<br />- <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">transform?: 'uppercase' | 'lowercase' | 'capitalize'</code> — transformación que se aplica en cada input.
<br />- <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">pattern?: string | RegExp</code> — expresión regular para validar caracteres permitidos; si la entrada no cumple, se previene la acción.
<br />
<br />Comportamiento principal
<br />------------------------
<br />- onKeyDown: valida la tecla pulsada contra <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">pattern</code>, controla longitud total y longitud de palabra actual, y permite teclas especiales (Backspace, flechas, Ctrl+C/V/X).
<br />- onPaste: valida el texto pegado contra <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">pattern</code>, <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">maxTextLength</code> y <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">maxWordLength</code>. Publica mensajes de error usando <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">PubSub.publish('alert', { ... })</code> cuando la validación falla.
<br />- onInput: aplica la <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">transform</code> configurada y trunca palabras que exceden <code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">maxWordLength</code>.
<br />
<br />Ejemplo de uso
<br />--------------
<br />En template:
<br />
<br />``<code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">html
<br /><input
<br />  cbmTextInput
<br />  [maxTextLength]="100"
<br />  [maxWordLength]="20"
<br />  [transform]="'capitalize'"
<br />  [pattern]="'^[A-Za-z0-9 ]*$'"
<br />/>
<br /></code>`<code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">
<br />
<br />Notas técnicas
<br />--------------
<br />- La directiva usa </code>PubSub<code class="bg-muted px-1 py-0.5 rounded text-sm font-mono"> (paquete </code>pubsub-js<code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">) para publicar alertas en el evento </code>paste<code class="bg-muted px-1 py-0.5 rounded text-sm font-mono"> cuando el contenido pegado no cumple las reglas. Asegúrate de tener un manejador global para </code>alert<code class="bg-muted px-1 py-0.5 rounded text-sm font-mono"> o sustituir esa lógica según tus necesidades.
<br />- </code>input()<code class="bg-muted px-1 py-0.5 rounded text-sm font-mono"> es usado para declarar inputs de forma compacta; la directiva lee estos valores en tiempo de ejecución.
<br />- Se permiten operaciones de portapapeles con Ctrl/C/V/X y navegación con flechas.
<br />
<br />Testing
<br />-------
<br />El proyecto incluye una spec base </code>text-input.directive.spec.ts<code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">. Ejecuta las pruebas con:
<br />
<br /></code>`<code class="bg-muted px-1 py-0.5 rounded text-sm font-mono">powershell
<br />ng test
<br /></code>``
<br />
<br />Contribuciones y mejoras sugeridas
<br />---------------------------------
<br />- Añadir soporte para reglas de validación más complejas (por ejemplo bloqueo por blacklist).
<br />- Hacer la publicación de alertas configurable (callback o servicio de mensajes en vez de PubSub directo).
