Close two long-standing issues against the static horizontal histogram (`p==`, `p==e`, `p==0` and the rest of the `p==X` family). Add the `scr.hist.width` / `scr.hist.height` config options (closes #6372), both clamped via RZ_MIN() against the current terminal size with a defensive sanity floor. Make the Y-axis ruler context-aware (closes #5290) via new `value_min` / `value_max` / `value_unit` fields on `RzHistogramOptions` and rescale each datum from its ut8 storage into the vmin..vmax display range before thresholding, which also fixes cer-0's follow-up about the chart's top rows staying blank for low-range data. Tighten the look in the same step. Y-axis labels are now sparse (top, ~25 %, ~50 %, ~75 %, bottom) instead of one per row, in the style of tokio-console / Granite, with an inclusive label range (top = vmax, bottom = vmin) decoupled from the threshold formula so the existing `_` baseline behaviour still appears. The bottom of the chart grows an X-axis ruler with `^` tick markers and `0x...` start / middle / end offsets (driven by a new `opts->blocksize` field). Two more options, `value_scale` and `value_precision`, let callers format ruler labels as fractional values; the `p==e` (entropy) command opts in with `value_max = 1, value_precision = 2` so the ruler reads 0.00..1.00 by default, matching Shannon-entropy convention. A new `opts->data_f` field lets callers feed double-precision data directly into the renderer (and engages double-precision arithmetic for the row thresholds), so entropy keeps full precision end-to-end instead of losing ~1/255 of resolution to the `(ut8)(255 * fraction)` quantisation step. This captures the precision win sketched in PR #6355 without introducing a separate `rz_histogram_horizontal_f64()` twin function. Ten unit tests in `test/unit/test_cons_histogram.c` (seven new) cover sparse labels, fractional labels, the X-axis offset ruler, the cer-0 regression, `opts->cols`, the legacy 0..255 ruler, and the fp data path; all pass.

Rizin
Rizin is a reverse engineering framework, born as a fork of the radare2, with a focus on usability, features and cleanliness.
Rizin is portable and it can be used to analyze binaries, disassemble code, debug programs, as a forensic tool, as a scriptable command-line hexadecimal editor able to open disk files, and much more!
To learn more on Rizin you may want to read the official Rizin book.
How to install
Look at install instructions on our web page.
How to build
Use meson to compile and install Rizin. Please make sure to get an updated
meson (e.g. get it with pip install meson if your system does not provide
one that is at least version 0.55.0).
Clone this repository:
$ git clone https://github.com/rizinorg/rizin
Then compile and install with:
$ meson setup build
$ meson compile -C build
$ sudo meson install -C build
Now you can use rizin:
$ rizin
-- Thank you for using rizin. Have a nice night!
[0x00000000]>
To uninstall rizin, execute sudo ninja -C build uninstall.
Please have a look at BUILDING.md for more information about building Rizin.
Contributing
We very much welcome any kind of contributions, from typos, to documentation, to refactoring, up to completely new features you may think of. Before contributing, we would like you to read the file CONTRIBUTING.md, so that we can all be on the same page.

Tools
Apart from the main tool rizin, there are also other tools tailored for specific purposes and
useful for shell scripting or as separate standalone tools:
rz-bin- provides all kind of information about binary formatsrz-ar- list and extract members from static archives (.a and .lib)rz-asm- a command-line assembler and disassemblersrz-diff- a tool to compare two binaries as raw data or analyzed executablesrz-hash- allows to calculate different hashes or even encrypt datarz-gg- a small "eggs" code generator useful for exploitation purposesrz-find- binary analog offindtool, allowing to search patterns and bit masksrz-sign- tool to create, convert and parse FLIRT signaturesrz-ax- a calculator and number format converterrz-run- a tool that allows to specify running environment and arguments for debugged file
Scripting
We provide a way to interact with Rizin from Python, Haskell, OCaml, Ruby, Rust, and Go languages through rzpipe. Other languages although not currently supported could be easily added.
Community
