%  Part 3: Array and other sizes for TeX, Metafont, etc.
%
% If you want to change some of these sizes only for a certain TeX
% variant, the usual dot notation works, e.g.,
% main_memory.hugetex = 20000000
%
% If a change here appears to be ignored, try redumping the format file.

% Memory. Must be less than 8,000,000 total.
%
% main_memory is relevant only to initex, extra_mem_* only to non-ini.
% Thus, have to redump the .fmt file after changing main_memory; to add
% to existing fmt files, increase extra_mem_*.  (To get an idea of how
% much, try \tracingstats=2 in your TeX source file;
% web2c/tests/memtest.tex might also be interesting.)
%
% To increase space for boxes (as might be needed by, e.g., PiCTeX),
% increase extra_mem_bot.
%
% For some xy-pic samples, you may need as much as 700000 words of memory.
% For the vast majority of documents, 60000 or less will do.
%
main_memory = 5000000 % words of inimemory available; also applies to inimf&mp
extra_mem_top = 0     % extra high memory for chars, tokens, etc.
extra_mem_bot = 0     % extra low memory for boxes, glue, breakpoints, etc.

% ConTeXt needs lots of memory.
extra_mem_top.context = 2000000
extra_mem_bot.context = 4000000

% Words of font info for TeX (total size of all TFM files, approximately).
% Must be >= 20000 and <= 147483647 (without tex.ch changes).
font_mem_size = 8000000

% Total number of fonts. Must be >= 50 and <= 9000 (without tex.ch changes).
font_max = 9000

% Extra space for the hash table of control sequences.
hash_extra = 600000

% Max number of characters in all strings, including all error messages,
% help texts, font names, control sequences.  These values apply to TeX.
pool_size = 6250000
% Minimum pool space after TeX's own strings; must be at least
% 25000 less than pool_size, but doesn't need to be nearly that large.
string_vacancies = 90000
% Maximum number of strings.
max_strings = 500000
% min pool space left after loading .fmt
pool_free = 47500

% Buffer size.  TeX uses the buffer to contain input lines, but macro
% expansion works by writing material into the buffer and reparsing the
% line.  As a consequence, certain constructs require the buffer to be
% very large, even though most documents can be handled with a small value.
buf_size = 200000

% Hyphenation trie.  The maximum possible is 4194303 (ssup_trie_size in
% the sources), but we don't need that much.  The value here suffices
% for all known free hyphenation patterns to be loaded simultaneously
% (as TeX Live does).
%
trie_size = 1000000

hyph_size = 8191        % prime number of hyphenation exceptions, >610, <32767.
                        % http://primes.utm.edu/curios/page.php/8191.html
nest_size = 500         % simultaneous semantic levels (e.g., groups)
max_in_open = 15        % simultaneous input files and error insertions, 
                        % also applies to MetaPost
param_size = 10000      % simultaneous macro parameters, also applies to MP
save_size  = 100000     % for saving values outside current group
stack_size = 5000       % simultaneous input sources

% These are Omega-specific.
ocp_buf_size = 500000   % character buffers for ocp filters.
ocp_stack_size = 10000  % stacks for ocp computations.
ocp_list_size = 1000    % control for multiple ocps.

% These work best if they are the same as the I/O buffer size, but it
% doesn't matter much.  Must be a multiple of 8.
dvi_buf_size = 16384 % TeX
gf_buf_size = 16384  % MF

% It's probably inadvisable to change these. At any rate, we must have:
% 45 < error_line      < 255;
% 30 < half_error_line < error_line - 15;
% 60 <= max_print_line;
% These apply to TeX, Metafont, and MetaPost.
