This is a tool to generate prefetch statements for downloads in BigFix ActionScript.

Suppose you want to create a prefetch statement to download this picture of Hodor.

The easiest way to do this is to run make-prefetch.py on the URL:

$ make-prefetch.py http://i.imgur.com/YAUeUOG.jpg

That will output a prefetch statement to download the picture:

prefetch YAUeUOG.jpg sha1:ce842e0af799f2ba476511c8fbfdc3bf89612dd0 size:57656 http://i.imgur.com/YAUeUOG.jpg sha256:74f69205a016a3896290eae03627e15e8dfeba812a631b5e0afca140722a322b

However, the file will be downloaded as YAUeUOG.jpg on the client. To instead download it as hodor.jpg, you can use the --name argument:

$ make-prefetch.py --name hodor.jpg http://i.imgur.com/YAUeUOG.jpg

This will output the same prefetch statement as before, but it will be downloaded as hodor.jpg on the client.

prefetch hodor.jpg sha1:ce842e0af799f2ba476511c8fbfdc3bf89612dd0 size:57656 http://i.imgur.com/YAUeUOG.jpg sha256:74f69205a016a3896290eae03627e15e8dfeba812a631b5e0afca140722a322b

Suppose you have already downloaded this picture of Hodor and you want to create a prefetch statement for it.

To do this, run make-prefetch.py on the file to generate a prefetch statement:

$ make-prefetch.py hodor.jpg

This will output a prefetch statement with http://REPLACEME as the URL:

prefetch hodor.jpg sha1:ce842e0af799f2ba476511c8fbfdc3bf89612dd0 size:57656 http://REPLACEME sha256:74f69205a016a3896290eae03627e15e8dfeba812a631b5e0afca140722a322b

To specify the URL to download the file from, you can use the --url argument:

$ make-prefetch.py hodor.jpg --url http://example.com/winterfell/hodor.jpg

This will output the same prefetch statement as before, but the URL will be http://example.com/winterfell/hodor.jpg.

prefetch hodor.jpg sha1:ce842e0af799f2ba476511c8fbfdc3bf89612dd0 size:57656 http://example.com/winterfell/hodor.jpg sha256:74f69205a016a3896290eae03627e15e8dfeba812a631b5e0afca140722a322b
