Outdated egg!

This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for the CHICKEN 5 version of this egg, if it exists.

If it does not exist, there may be equivalent functionality provided by another egg; have a look at the egg index. Otherwise, please consider porting this egg to the current version of CHICKEN.

This page is maintained in the package's github repository.

scheme2c-compatibility

This implements miscellaneous functions and macros that make Chicken more compatible with Scheme->C. Some of this comes from from Jeff Siskind's QobiScheme. Much of this functionality is redundant with that offered by other Chicken eggs but is offered with a Scheme->C-compatible API and naming scheme.

Lists

eleventh xprocedure

twelfth xprocedure

Strings

lines stringprocedure

Combine a list of lines into a string separated by newlines.

unlines lprocedure

Split a string into a list of lines.

words stringprocedure

Split a string into words.

unwords lprocedure

Combine a list of words into a string separated by spaces.

System

usleep microsecondsprocedure

directory-list dprocedure

File IO

read-object-from-file pathnameprocedure

write-object-to-file object pathnameprocedure

Read/write a single scheme object to/from a file. This is not the same as chicken's read-file.

Temporary files

*tmp*parameter

tmp pathnameprocedure

with-temporary-file prefix fprocedure

Call f with a unique filename that will be removed once f returns. The extension of prefix is honored, but not its base filename.

pointer-pointer-set! ptr-to-ptr valprocedure

c-string->string bufprocedure

c-null-separated-strings->strings c-stringsprocedure

Access buffers containg various standard types. s2cuint is the same size as a pointer.

vector->c-array array v set-element element-sizeprocedure

vector->c-exact-array array v element-size signed?procedure

vector->c-inexact-array array v element-size signed?procedure

Various functions to convert to and from C arrays.

c-sized-int-ptr-ref size signed?procedure

c-sized-int-ptr-set! size signed?procedure

c-sized-inexact-ptr-ref size signed?procedure

c-sized-inexact-ptr-set! size signed?procedure

Return functions which access arrays with elements of given sizes.

Scroped

with-alloc x fprocedure

with-buffer-stream f buffer size modeprocedure

with-c-string str fprocedure

with-file-stream f filename modeprocedure

with-array elements element-size fprocedure

with-c-pointers f vprocedure

with-vector->c-array f set-element element-size vprocedure

Perform many of the operations above automatically cleaning up once the procedure returns.

misc

exact-round xprocedure

exact-ceiling xprocedure

exact-floor xprocedure

Round/floor/ceiling and inexact->exact.

c-valuesyntax

c-sizeofsyntax

xor a bprocedure

*panic?*parameter

*program*parameter

read-from-string stringprocedure

(read) from a string.

flush-bufferprocedure

flush-output

TODO

with-temporary-file is wrong! It ignores the prefix and more importantly its extension and will lead to breakage.
