Starting a web browser

From Rosetta Code
Starting a web browser is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

Build and show a web page displaying the data from the task separate the house number from the street name in a formatted and colored table.

Task

Write the code which automatically opens a web page in a browser showing the addresses. No static data must be shown, only processed data.

EchoLisp

Since we are already in a browser window, the browser is started. print-hatml sends an html string to the standard output area. The table is styled with the "htable" css class, which is included in EchoLisp. 

;; table from "Separate_the_house_number_from_the_street_name"

Here, we assume that browser refers to a browser in a format which is usable by a command shell, and din5008 and sampledata have been defined according to the J house number street name task entry: 

   wrap=: {{'<',m,'>',y,'</',(;{.;:m),'>' }}(L:0)("1)

1660
   launch browser,' table.htm'

(Here, 1660 was the length of the generated file.)
