Grantha

This is a collection of functions I tend to use. The package aims at being self-contained, and for that I might copy functions from elsewhere: which one is worse, dependecy hell or redundancy?

grantha-

Skt. an artificial arrangement of words, verse, composition, treatise, literary production, book in prose or verse, text (opposed to artha ‘meaning’).

Installation

Tested with sbcl and clisp.

list of exported symbols

ROUND-TO (function)

I round NUMBER to PRECISION.

LIST-EXPORTED-SYMBOLS-WITH-DOCSTRINGS (function)

I return a simple definition list in org-mode with the exported symbols of a package. I should do that in the order they are defined in the source code, but I do not.

CONCAT (function)

I try to be smart in concatenating items, silently converting them to strings.

PADDING (function)

Give me a string, the length it should have, and what to pad it with, and I shall return thee the selfsame string thus padded.

PRINT-HEX (function)

I print the given number in a hexadecimal representation.

LAST-MEMBER (function)

I return the actual last member of a list.

GET-ODD-ELEMENTS (function)

Give me a list and I shall return thee its odd elements.

TRUNCATE-TIME (function)

Give me some seconds, and them I shall return thee divided by the maximum possible unit, together with that unit.

PARSE-TIME (function)

I either return thee the current `get-decoded-time’ as a plist, or I parse the time given in the same format, that thou providest me.

STR (function)

I return i represented as a string.

HUMAN-READABLE-NUMBER (function)

PRINT-BIN (function)

I print the given number in a binary representation.

CHAR-TO-INT (function)

Give me either a character or a list of them, and I shall return them converted to ints to thee. I am the contrary of `int-to-char’.

MAKE-PLIST (function)

Construct a property list from KEYS and DATA.

INT-TO-STR (function)

Give me either an int or a list of them, and I shall return them as a string, after converting them to characters. I am the contrary of `str-to-int’.

TIME-TO-EXECUTE-AND-RESULT (function)

Returns the time (always in miliseconds?) to execute FORM, and its result.

INT-TO-CHAR (function)

Give me either an int or a list of them, and I shall return them converted to chars to thee. I am the contrary of `char-to-int’.

CURRENT-DATE-STRING (function)

I return thee a string with the current date, and time if thou so wishest, and likewise the timezone. Cf. ISO 8601. Time should be separated with ‘T’ instead of ‘_’, but Edgard thinks it less legible.

SUBTRACT-TIME-OF-DAY (function)

I get two times in the format (seconds microseconds), returned by `get-time-of-day’ for instance, and return their difference.

PRETTY-NUMBER (function)

I truncate the bytes you give me. I am more expensive than `truncate-memory’.

PREVIOUS (function)

Give me something, like an integer, a character, or a string, and I will return thee the previous one of its kind. I am the contrary of `next’.

TRUNCATE-MEMORY (function)

Give me some bytes, and them I shall return thee divided by the maximum possible unit, together with that unit.

GARBAGE-FULL (function)

I ask for full garbage collection and return thee the number of bytes freed. Sometimes I return negative numbers, what should I do with them?

GET-EVEN-ELEMENTS (function)

Give me a list and I shall return thee its even elements.

STR-TO-INT (function)

Give me either a string or a list of them, and I shall return everything as a list, after converting them to integers. I am the contrary of `int-to-str’.

NEXT (function)

Give me something, like an integer, a character, or a string, and I will return thee the next one of its kind. I am the contrary of `previous’.

ALIAS (function)

Makes an alias named QUOTED-NEW-NAME for QUOTED-PREV-NAME.

REVERSE-CONS (function)

I reverse a cons pair.

CONVERT (function)

I try converting the given quantity from the before unit to the after unit. I am not smart. Check `*equivalences*’ to see all I know.
