СпутникиРНSpaceXРоскосмосNASA I am happy to announce a new major release of GNU poke, version 5.0.
GNU poke 5.0 release is now available at
https://ftp.gnu.o ... e/poke-5.0.tar.gz
The tarball is signed and you can get the PGP signature at
https://ftp.gnu.o ... ke-5.0.tar.gz.sig
GNU poke (http://www.j ... rch.net/poke) is an interactive, extensible
editor for binary data. Not limited to editing basic entities such
as bits and bytes, it provides a full-fledged procedural,
interactive programming language designed to describe data
structures and to operate on them.
I'd like to thank everyone who contributed to this release through code,
documentation, or testing.
What is new in this release:
User interface updates
Now hyperlink server can bind to a user-specified port for listening to
commands (-p, --hserver-port).
Poke Language updates
Floating-point arithmetic is now supported on uint<32>/uint<64> types.
uint<32> will be interpreted as a single-precision floating-point number
and uint<64> will be interpreted as a double-precision floating-point
number as defined per the IEEE 754 standard.
The following expressions are now supported:
- Addition: a .+ b
- Subtraction: a .- b
- Multiplication: a .* b
- Division: a ./ b
- Ceil-devision: a ./^ b
- Exponentiation: a .** b
- Remainder: a .% b
- Post-increment: a.++
- Pre-increment: .++a
- Post-decrement: a.--
- Pre-decrement: .--a
- Negation: .-a
- Less-than: a .< b
- Less-than-or-equal-to: a .<= b
- Greater-than: a .> b
- Greater-than-or-equal-to: a .>= b
- Equal-to: a .== b
- Not-equal-to: a .!= b
Poke Runtime updates
Thanks to the great work of David Faust, poke now supports reactive IO
spaces! Extent of a PVM value mapped in a given IO space will be tracked
and values will be re-mapped only if a write happens in their extent; which
is a big performance win for read-intense programs.
A bunch of undefined behavior (UB) releated to left-shifts has been fixed.
Improved human-readable message of E_conv exception when verifying
length/size of an array with dynamic bound(s) to help the user to
understand the mistake.
Poke compiler updates
Now poke can properly handle writes to nested integral struct/unions
fields. Previously write to nested fields of integral structs did not
materialize in IO space.
Standard Poke Library updates
Closure's pretty printer now adds closure's name (identifier) to output.
Two new functions to calculate square root of single and double precision
floating point numbers: sqrtf and sqrtd.
They accept uint<32> and uint<64> respectively as the IEEE 754 single and
double precision floating-point numbers.
libpoke updates
Version of DSO is bumped to 2.0.0, and from this release onward, we try
to not break the ABI, and bump the version components according to the
libtool's recommendation (when needed).
To be able to keep the ABI backward-compatibility promise, all public APIs
are now accepting either pk_compiler or pk_val. This is the first step
toward removing global state from libpoke to be able to have multiple
instances of libpoke in a single process (and also to be able to accomplish
thread-safety). We're not there yet, but we'll be there some day (hopefully
soon)!
IO subsystem updates
IOS_F_TRUNCATE has been re-introduced (it was removed after release of
poke 1.0 by the rationale that it's not that useful of a flag. Turns
out it's quite useful to start from an empty file when assembling binary
files from scratch using poke.
Pickles updates
Improved ustar pickle and add tests. Method get_last_mod_time has been
fixed and the following methods has been added:
get_{file,owner_user,group}_name.
Improved time pickle to print date and time properly (zero-padded), and
also add ptime_str function to get date/time information as a string.
Platform supports
We tried to improve MinGW compilation situation by importing more Gnulib
modules, but we still cannot have poke executable for MinGW platform.
Help is very much appreciated in this area!
Documentation updates
Thanks to people who actually read the reference manual, this release
includes a bunch of corrections to the documentation! Cheers to them!
Happy poking!
