6116a83fbb 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.

6f21e51667 modules: [0/n] introduce a new structure ecl_module in the system 
This will allow us to decouple forward system initialization from the early
process code.

0846b149df process: use GC_thread_is_registered() instead of the_env->cleanup 
This allows us to remove unnecessary bookkeeping.

add69a9b1a 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.

9348ddf462 signals: introduce signals to the early environment 2026-03-08 20:01:34 +01:00

8a411415b7 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.

e8eefd5963 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).

67f22249de 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.

6f22cbd27d reader: store separately macro and a dispatch table 
This improves code readibility, because dispatch macro characters are built on
top of "normal" macro characters.

27fb51b98f 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.

83aa9b8df4 reader: low level functions accept explicit readtable argument 
Previously the readtable was accessed as a value of a variable *READTABLE*.

9369946933 reader: add new operators and fix found regressions 
- low limit in escapes was off-by-one
- quoted character immediately after :, like :|foo| did not pare correctly

29a4a2c51a reader: separate token parsing from token reading 
Parsing the token ends in a separate file.

6828cb7005 reader: use token object to pass tokens prior parsing 2026-03-07 22:42:12 +01:00
Daniel Kochmański
d495a41464 reader: add a new object to the system ecl_token 
It represents unparsed token constructed by the reader.

8281d2316f 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.
 2026-03-07 22:42:12 +01:00
Daniel Kochmański
26b556ea00 reader: turn ecl_read_token into symbol/number parser 
First it call ecl_only_read_token and then it parses it.
Fixes #814.
 2026-03-07 22:42:12 +01:00
Daniel Kochmański
4e7aa4e358 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.

2b36abd0b7 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.
 2026-03-07 22:42:12 +01:00
Daniel Kochmański
832850bdee 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.
