Description:

abcde is a script extraction/insertion utility that aims to take as many of the things that are good about Atlas and Cartographer as possible and make them even better.

Features:

  • Implements all features supported by Cartographer.
  • Implements all features supported by Atlas except for running Atlas extensions.
  • Corrects many features that were broken to varying degrees in Cartographer and Atlas.
  • Uses expanded table file syntax that allow you to:
    • Work with non-octet text encodings (e.g. 6-bit tokens, Huffman encodings, etc.).
    • Handle mid-string encoding changes (a.k.a. table switching within a single string) with a great deal of flexibility.
  • Adds new extraction commands that allow you to:
    • Dump multiple strings from a single pointer.
    • Re-align the ROM read position when an end token is encountered.
    • Dump strings with internal gaps.
    • Sort output by string address instead of pointer address (making it easier to find gaps between strings that might indicate unused content).
    • Output only one copy of strings that are the target of multiple pointers.
    • Output more Atlas commands automatically; in many cases it is possible to use the extraction output as a complete Atlas input file without needing to modify it further.
  • Adds new insertion commands that allow you to:
    • Execute arbitrary insertion commands when the insertion point reaches a specified ROM address.
    • Count things and write the counter value to ROM like a pointer.
    • Handle Pascal strings that specify their length in number of tokens rather than number of bytes.
    • Write pointers (embedded or normal) whose value is the distance between the pointer and the text rather than the text’s address.
    • Change the current insert position by a relative amount rather than specifying an absolute ROM address.
    • Dynamically calculate arbitrary arithmetic values and write the values to ROM.
  • Open source code that you can modify or extend to suit your own needs or preferences.
