MGTize

Priskribo de la ĉi-paĝa enhavo

Programo por faciligi la uzon de pyz80 por krei disked-kopian MGT-dosierojn por SAM Coupé.

Etikedoj:

MGTize estas envolvaĵo por pyz80, de Andrew Collier, Z80-asemblilo fokusita en transprogramado por SAM Coupé. La celo de MGTize estas plifaciligi la kreon de disked-kopiaj MGT-dosieroj per pyz80.

Por krei disked-kopian MGT-dosieron per pyz80 endas aparte mencii ĉiun dosieron per la parametrilo -I, kaj krome Z80-dosieron asembli, eĉ malplenan: necesas ion asembli. Do la komanda linio povas tre longiĝi:

touch empty.z80s
pyz80 -I pict1.png -I pict2.pbm -I pict3.pgm -I pict4.ppm -I too.jpg -o result.mgt.gz empty.z80s
rm empty.z80s

MGTize plifaciligas tion: La una parametro esta la nomo de la nova MGT-dosiero (kies sufikso «.mgt.gz» estos poste aldonita aŭ kompletigita senecese; jama samnoma dosiero estos forviŝita). Ceteraj parametroj estas nomoj de inkludendaj dosieroj, kaj eblas uzi ŝablonojn de la sistema komandlinio: Kompreneble, ne necesas dosieron de Z80-fontprogramo: MGTize kreas unu malplenan dosieron, kiu estos «asemblita» kaj forviŝita. Ekzemple, jen la koresponda supra ezkemplo per MGTize:

mgtize result pict?.p* too.jpg

MGTize estas verkita Fortho per Gforth. Ĝi bezona du Forthajn bibliotekojn: Forth Foundation Library kaj Galope (ankore ne publikigita, sed la necesaj difinoj estas inkluditaj en la fontprogramo).

En la fontprogramo estas inkluditaj, kiel komentaro, simplaj angla-lingvaj instal-instrukcioj.

\ Description

\ MGTize creates a gzip-compressed SAMDOS MGT disk image with the
\ desired files.  The MGT disk image can be used with SimCoupe, the
\ SAM Coupé emulator (<http://simcoupe.org>), or copied to a diskette.
\
\ MGTize is a wrapper for Andrew Collier's pyz80 (version 1.1,
\ 2007-04-13): <http://www.intensity.org.uk/samcoupe/pyz80.html>.
\
\ MGTize was written to make it easier to use pyz80 when you just want
\ to create a MGT disk image with several files, not to compile any
\ Z80 code. 
\
\ MGTize is written in Forth with Gforth:
\ <http://gnu.org/software/gforth>,
\ <http://www.complang.tuwien.ac.at/forth/gforth/>.

\ \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
\ Installation on Linux systems

\ 1. Gforth (http://gnu.org/software/gforth) and the Forth Foundation
\ Library (http://irdvo.github.io/ffl/) must be installed.
\
\ 2. Make sure this source file is executable, with the following
\ command:
\
\   chmod ugo+x mgtize.fs
\
\ 3. Copy, move or link this source file to your path (ussually to
\ </usr/local/bin/>), with the desired name (e.g. without the
\ extension). Example command:
\
\   sudo ln mgtize.fs /usr/local/bin/mgtize
