  28. help
  29. Store bbconfig data in compressed form, uncompress them on-the-fly
  30. before output.
  31. If you have a really tiny busybox with few applets enabled (and
  32. bunzip2 isn't one of them), the overhead of the decompressor might
  33. be noticeable. Also, if you run executables directly from ROM
  34. and have very little memory, this might not be a win. Otherwise,
  35. you probably want this.
  36. config BUSYBOX_BC
  37. bool "bc (45 kb)"
  38. default y
  39. select BUSYBOX_FEATURE_DC_BIG
  40. help
  41. bc is a command-line, arbitrary-precision calculator with a
  42. Turing-complete language. See the GNU bc manual
  43. (https://www.gnu.org/software/bc/manual/bc.html) and bc spec
  44. (http://pubs.opengroup.org/onlinepubs/9699919799/utilities/bc.html).
  45. This bc has five differences to the GNU bc:
  46. 1) The period (.) is a shortcut for "last", as in the BSD bc.
  47. 2) Arrays are copied before being passed as arguments to
  48. functions. This behavior is required by the bc spec.
  49. 3) Arrays can be passed to the builtin "length" function to get
  50. the number of elements in the array. This prints "1":
  51. a[0] = 0; length(a[])
  52. 4) The precedence of the boolean "not" operator (!) is equal to
  53. that of the unary minus (-) negation operator. This still
  54. allows POSIX-compliant scripts to work while somewhat
  55. preserving expected behavior (versus C) and making parsing
  56. easier.
  57. 5) "read()" accepts expressions, not only numeric literals.
  58. config BUSYBOX_DC
  59. bool "dc (36 kb)"
  60. default y
  61. help
  62. dc is a reverse-polish notation command-line calculator which
  63. supports unlimited precision arithmetic. See the FreeBSD man page
  64. (https://www.unix.com/man-page/FreeBSD/1/dc/) and GNU dc manual
  65. (https://www.gnu.org/software/bc/manual/dc-1.05/html_mono/dc.html).
  66. This dc has a few differences from the two above:
  67. 1) When printing a byte stream (command "P"), this dc follows what
  68. the FreeBSD dc does.
  69. 2) Implements the GNU extensions for divmod ("~") and
  70. modular exponentiation ("|").
  71. 3) Implements all FreeBSD extensions, except for "J" and "M".
  72. 4) Like the FreeBSD dc, this dc supports extended registers.
  73. However, they are implemented differently. When it encounters
  74. whitespace where a register should be, it skips the whitespace.
  75. If the character following is not a lowercase letter, an error
  76. is issued. Otherwise, the register name is parsed by the
  77. following regex: [a-z][a-z0-9_]*
  78. This generally means that register names will be surrounded by
  79. whitespace. Examples:
  80. l idx s temp L index S temp2 < do_thing
  81. Also note that, like the FreeBSD dc, extended registers are not
  82. allowed unless the "-x" option is given.
