bd95bbe6df process: move process initialization to the process module hooks 2026-04-19 19:54:36 +02:00

5e42a59cc7 garbage: register and unregister GC threads manually from a module 
This decouples thread primitives from the garbage collector and allows us to
build nucl once more.

65da16bc7d process: abstract away create thread, exit thread and sigmask 
Previously we've opencoded calls to these functions, although they may be nicely
abstracted with static inline functions. This change improves code readibility
and portability.

2450a1483b modules: [1/n] introduce ecl_module_gc 
We also remove conditionalization for garbage collector inclusion in autotools.
When we propose an alternative gc, then we may decide to put them back, or to
add necessary ifdef statements directly in files.

Moreover untangle c-stack from the gc code and assign the stack base with a
rough guess only when it is not initialized yet (GC will always fill it).

Finally remove a kludge from ecl_adopt_cpu and disable colleciton until the cpu
is fully initialized.

54cf51d27c modules: [0/n] introduce a new structure ecl_module in the system 
This will allow us to decouple forward system initialization from the early

79749d8400 signals: define *SIGNAL-HANDLERS* in cold_boot 
I've also renamed *HANDLER-CLUSTERS* to a more appropriate *SIGNAL-HANDLERS*.
Currently this symbol is imported to the SYSTEM package, although this may be
revised in the future to cater to multiple global environments. Alternatively
the SYSTEM package may be common to all runtimes.

940cf78f85 signals: rewrite signal handling to use functions and not lists 
Instead of storing lists in *HANDLER-CLUSTERS*, we define functions that are
called unconditionally on the handler. HANDLER-BIND defines that function to be
a typecase that is dispatched based on the conditiont type, as specified by CL.

This change will aid further refactor.

971d6df472 boot: move ecl_eql to a separate file eql.d 
This is a low-level comparison operator. We opencode EQL comparison for bignums
to avoid a dependency on GMP (in this file).

07bcb949fb hash: rename cl__make_hash_table to ecl_make_hash_table 
The latter name follows the codebase convention that functions that do not work
in the environment have a prefix ecl_. The old name is defined in legacy.h.

57b23ec224 hash: use explicit ecl_returnX forms instead of (@return) 
This also fixes an issue, where si:hash-table-synchronized-p did not populate
VALUES (it used raw return).

633dec58ab reader: open-code token-specific version of ecl_push_string_extend 
This way we make the reader independent of string.d and array.d while still
enabling adjustable token buffers.

ee88dfcba0 reader: store separately macro and a dispatch table 
This improves code readibility, because dispatch macro characters are built on
top of "normal" macro characters.

adc8540857 reader: turn separate parameters into flags in low-level read 
Instead of passing parameters as values, we make a bitfield:

ECL_READ_LIST_DOT, ECL_READ_RETURN_IGNORABLE, ECL_READ_SUPPRESS,
ECL_READ_ESCAPE_FIST;

this way we don't rely on a dynamic variable in a low-level function.

59e43024ec reader: low level functions accept explicit readtable argument

b8f9a71ecc reader: separate token parsing from token reading

c7ff0b93a7 reader: add a new object to the system ecl_token 
It represents unparsed token constructed by the reader.

702f01968d reader: cleanup of mapping over escape intervals 
This still needs some work, but we remove CONS in favor of flat list of even
number of elements and simplify loops over them.

f6a449a1b2 reader: turn ecl_read_token into symbol/number parser 
First it call ecl_only_read_token and then it parses it.
Fixes #814.

Daniel Kochmański
f4824754f2 reader: factor out ecl_read_only_token from ecl_read_token 
The end goal is to make ecl_read_token become ecl_parse_token and read tokens
only from ecl_read_only_token, to keep Common Lisp -specific processing out of
the token reader.

dea815abcb reader: store escape intervals on a stack 
To enable access from both sides we store escape intervals in a vector (a
stack). This also fixes #813.
 2026-04-19 19:54:35 +02:00
Daniel Kochmański
b24902574d reader: always cons full escape_list 
This is in preparation for separating CL-specific tokenization from general
rule. We need to carry information about all escaped characters even when we
don't change their case, this is to allow for interpretation of special token
characters, like ":" - when it is escaped then it has no meaning, otherwise it
separates the symbol from the package.
