poke @ Savannah: GNU poke 5.0 released
Planet GNU ·
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! Mohammad-Reza Nabipoor
