reASITIC ↔ ASITIC C function mapping¶
Living catalog of every Python function in the reASITIC port and the
reverse-engineered C function(s) it ports / mirrors / supersedes. The
C side lives in ../decomp/output/asitic_*.c; addresses are absolute
load-time virtual addresses inside run/asitic.linux.2.2.
The relationship column uses these tags:
Tag |
Meaning |
|---|---|
port |
Direct re-implementation of the C body (formula or logic preserved) |
partial |
Implements a subset of the C function’s behavior |
subsumes |
Replaces multiple C helpers with one Python implementation |
dispatch |
Mirrors the C dispatcher’s call but lets cleaner code do the work |
stub |
Placeholder; full port deferred to a later phase |
utility |
Python-only helper; no direct C analogue |
pure |
Pure-Python implementation of standard math (no C analogue) |
When updating: add a row whenever a new Python function is written. Keep the table sorted by Python module path, then by function name.

Subsumed by NumPy / SciPy / Python stdlib¶
Many of the binary’s small numerical helpers are direct one-liners in NumPy / SciPy / Python and do not need their own Python module. They are listed here so the coverage accounting reflects them:

|
These bookkeeping rows account for 31 backend / utility C functions that need no dedicated Python implementation.
Frontend (asitic_repl.c) bulk coverage¶
The frontend file (decomp/output/asitic_repl.c, 320 functions)
contains the REPL command handlers, X11/GL drawing code, file I/O
wrappers, parsing helpers, and C-runtime startup/shutdown glue.
The substantive surface (~117 commands plus the X11/Tek frontend)
is fully ported via :mod:reasitic.cli and :mod:reasitic.gui;
the C-runtime / memory-management / RTTI infrastructure is
subsumed by Python and needs no dedicated equivalent.
REPL command handlers (subsumed by reasitic.cli.Repl)¶
The 71 cmd_* functions in the binary are individually ported
through :class:reasitic.cli.Repl’s dispatcher, which exposes all
117 binary REPL commands. The decomp-name → Python-method
correspondence:
Geometry builders:
cmd_3dtrans_create,cmd_balun_create_new/cmd_balun_edit_args,cmd_capacitor_create_new/cmd_capacitor_edit_args,cmd_mmsquare_build_geometry/cmd_mmsquare_create_new,cmd_optl_search,cmd_optlsympoly_search,cmd_optlsymsq_search,cmd_optarea_search→ corresponding Python builders / optimisers.Edit ops:
cmd_copy_clone,cmd_erase_remove,cmd_flip_apply/cmd_fliph_apply/cmd_flipv_apply,cmd_join_apply/cmd_joinshunt_apply,cmd_modifytechlayer_apply→ corresponding Python methods.Network ops:
cmd_2portgnd_emit,cmd_2portpad_emit,cmd_2porttrans_emit,cmd_2portx_emit,cmd_3port_emit,cmd_lmat_print→ correspondingnetwork/functions.Optimisation:
cmd_batchopt_run,cmd_optarea_search,cmd_optl_search→optimise/module.Persistence / I/O:
cmd_bload_finalize/cmd_bload_read,cmd_bsave_finalize/cmd_bsave_write,cmd_bcat_dump,cmd_cat_dump,cmd_load_apply/cmd_load_open,cmd_cifsave_emit→ JSON save/load + CIF export.Info:
cmd_bb_show_bounding_box,cmd_findi_search,cmd_help_emit_topic,cmd_listsegs_show,cmd_options_print,cmd_pause_wait_for_key,cmd_ver_print,cmd_showldiv_print/cmd_showldiv_format→ corresponding REPL handlers.
Additional cmd_* names ported through the dispatcher (one
function per binary command in the decomp; one Python method per
command in :class:reasitic.cli.Repl):
cmd_optpoly_search, cmd_printtekfile_emit,
cmd_rename_apply, cmd_ring_create_new /
cmd_ring_edit_args, cmd_rotate_apply,
cmd_save_emit / cmd_save_open, cmd_scale_apply,

X11 UI helpers (subsumed by :mod:reasitic.gui)¶
The 9 unported xui_* functions are layout / drawing helpers
that map onto Tk Canvas calls in our :class:reasitic.gui.GuiApp:
xui_alert_bell (Tk bell()), xui_render_dimension_labels_for_shape
(canvas text), xui_render_selected_shape_into_pixmap (Tk image
buffer), xui_render_with_dimension_labels (combined), the
substrate redraw helpers, and the cursor-state managers.
Save-format emitters (subsumed by :mod:reasitic.persistence)¶
The 14 save_emit_* / save_chain_* functions emit the
binary’s BSAVE format (a binary blob tied to internal struct
layouts) one record at a time. The Python port replaces this with
JSON serialisation in persistence.save_session /
load_session, which is portable and human-readable. The
explicit decomp names: save_emit_NAME_line, save_emit_AX_line,
plus save_chain_* linked-list manipulators.
C runtime / memory / RTTI (subsumed by Python)¶
Everything under crt_*, _init / _fini,
__do_global_dtors_aux, destroy_*, init_* (besides
init_x11_and_gl which is the GuiApp constructor),
alloc_check_ptr_or_die, cxx_destroy_simple_with_array,
crt_register_frame_info, compute_dqagi_wrapper /
green_function_dqawf_wrapper (QUADPACK wrappers, subsumed by
:func:scipy.integrate.quad), flush_to_screen,
format_complex_pi_print, fortran_io_format_E (libf2c).
Total: ~80 C-runtime helpers with no Python equivalent.
Argument parsing (subsumed by argparse / cli.Repl)¶
argv_check_exec_or_redirect_needs_tech,
argv_print_two_column_table, abort_current_command_with_help,
dispatch_command, execute_script_file — all absorbed by
:class:reasitic.cli.Repl and the argparse setup in
reasitic.cli.main.
Frontend infrastructure (subsumed by Python runtime)¶
The following frontend helpers have no dedicated Python equivalent because they are pure C-runtime / memory-management / logging / I/O glue subsumed by Python:

Polygon record helpers and remaining infrastructure¶
The polygon-record / output-format / OOM-handler / prompt /
warn-user / I/O helpers — all subsumed by Python equivalents
(Polygon dataclass + native string formatting + Python
exceptions):
Vendored libraries (asitic_lapack.c / _linpack.c / _libf2c.c / _cxxrt.c)¶
The 200 functions in the four vendored-library files are not
ASITIC’s own code — they’re statically linked LAPACK / LINPACK /
QUADPACK Fortran routines (run through f2c), libf2c’s Fortran
I/O runtime, and the libstdc++-2.9 / SGI STL C++ runtime. The
Python port replaces every one of them with stdlib / scipy
equivalents:
Vendored cluster |
Python equivalent |
|---|---|
LAPACK / BLAS (49 funcs in |
|
LINPACK / SLATEC / QUADPACK (13 funcs in |
|
libf2c (94 funcs in |
Python stdlib I/O ( |
libstdc++-2.9 / SGI STL / MV++ (44 funcs in |
Python built-in types ( |
These are infrastructure functions with no Python equivalent written by us — they are absorbed wholesale by the Python runtime + scientific stack.
