Do you think if it's useful to provide a function that converts all the hex numbers in the buffer to decimal numbers?
For example, something like 0xc-convert-buffer that converts

<tag1>0x4</tag1>
<tag2>0x3</tag2>
<tag3>0x1 0x2 0x3<tag3>

to

<tag1>4</tag1>
<tag2>3</tag2>
<tag3>1 2 3<tag3>

I imagine this can be done by re-search-forward for 0x[0-9a-f]+ and call 0xc-convert-point?

I was looking for a command like M-x number-base-at-point-cycle. If I'm in c-mode and I have 0123 (octal) at point, it would convert it to 83 (decimal). If I then used the command a second time, it would convert the number to 0x53 (hex). A third time, back to 0123 (octal). If I'm in nasm-mode it would know that NASM also has 0b1010 syntax for binary literals so it would cycle through that as well. If I used the command in lisp-mode it would know that Lisp spells numbers like #x-123 (hex) and would do the same thing in a mode-sensitive fashion. This command could then be used in keyboard macros to convert many numbers at once. Actually we could have:

• number-base-at-point-to-binary
• number-base-at-point-to-octal
• number-base-at-point-to-decimal
• number-base-at-point-to-hex
• number-base-at-point-cycle

Each of them could take an optional prefix argument to specify the number of digits in the resulting number, so the result would be padded with leading zeros where needed.

Do you think such a command would be a good fit for this package, or too different?

Hi,

I tried using 0xc after installing it from MELPA. I tried to do a simple conversion of the number 10 to hexadecimal, just to get a feel for how this works. However, everything I try seems to end up with this error:

0xc-string-to-number: Wrong type argument: stringp, nil

This error occurs when I try 0xc-convert-point as well. I'm not sure whether I'm just using this package incorrectly or if this is a bug. In either case, there's not enough documentation here for me to tell. FYI, I'm using Emacs 25.1.1 on OS X 10.11.6.

In the package listing (M-x list-packages) this package is missing it's description.

You should add something like this into the comments at top of the file:

;;; 0xc.el --- Base 10 number conversion utility.

I think it would be great to have an example section in the README file. So people can get to know this great package easier! Thanks!

as title. Thanks!
