This is one of the built-in variables for Make and can increase
portability on different operating systems (eg, on Windows, the
built-in $(RM) may be defined as "del" instead of "rm -f").
Might have been a nice idea to be able to run under absolutely any
Doom engine, this has caused problems with PrBoom-Plus for
compatibility, with that engine detecting our game as a BFG Edition
IWAD and applying certain workarounds that don’t actually make sense
in this case.
It is a rather niche use case to run under BFG Edition, and proper
PrBoom-Plus compatibility is much preferred.
Some of the sprites have changed since the help screen was first put
together and are now overlapping with each other slightly. In
particular the box of shells is overlapping with the weapon above it.
Adjust positions by a couple of pixels and give some extra space.
DOOM2.WAD contains a MAP33, which is being represented here as only
the dummy map, and also M_EPI1 and M_EPI2 lumps for the “Hell on Earth”
and “No Rest for the Living” texts, both of which are now replicated
here as well (using “Phase 2” and “The Missing Levels” as names instead).
No, we still don’t plan on having a real MAP33, the inclusion here is
only to avoid engine crashes.
Fixes: #533
Ref: #529
There are a few lumps added to the Doom IWADs required by the BFG Edition
of the game that would cause it to crash abnormally if the IWADs were
replaced by Freedoom. We add these news graphics lumps to the game here.
BFG Edition also changes m_gdhigh to "Fullscreen:" and m_scrnsz to
"Gamepad:", neither change of which will ever be reflected in Freedoom,
but it won't crash in this engine anymore.
Closes: #529
textgen: instead of running ImageMagick yourself, output a Makefile rule
for each graphic. Dependencies are passed on the command line.
Makefile: Add rule for 'textgen.mk' which is built by running textgen.
graphics.stamp depends on textgen.mk and all the built graphics files.
Then, each built graphic depends on textgen.mk, ensuring it is made
first. textgen.mk itself depends on textgen config, font, and dehacked.
(Makefile itself also depends on textgen.mk implicitly via include)
This duplicates previous behaviour where changing textgen config remakes
all text graphics, but one Make rule for each, allowing parallel make
with -j instead of the script doing one at a time.
The built IWADs are byte-for-byte identical before and after this patch
series is applied (provided VERSION is set to the same thing of course)
One problem is 'make clean' rebuilds textgen.mk because Make thinks the
Makefile needs it, but then immediately deletes it. Not sure how to fix.
Use git clean -fdx instead, or just don't clean twice in succession.

This gives the following improvement in build time (-j1 as control,
built on 4 cores and a large tmpfs so disk speed isn't a factor)

These images contain the names of the FreeDM intermission screen
level names and need to be copied to the parent directory along
with the CWILV* and WILV* graphics. This fixes a bug introduced
by the earlier desymlinkification of the textgen graphics.
Previously left alone, and with the old font, due to their special
nature, but since then, the small-text generator exists too! Only
thing special is that wikilrs is rotated, which is resolved simply by
using ImageMagick.
Closes#184
This is one of the screens of text shown between demos in the demo
loop. Generate this from the contents of a static text file. I
originally wanted to generate this programatically from the CREDITS
file but there are too many contributors to fit them all on the page.
Instead of generating text and image parts in separate stages, add
the ability to include an image in the smtextgen command line. This
makes the command line in the Makefile clearer.
The original Doom HELP screen showed the default key bindings for the
game's controls. This is not so useful nowadays: at worst it's
outright misleading because the player might not be using the
defaults, but it's also redundant because most modern source ports
allow the key bindings to be changed via the menus, which doubles as a
convenient list of the current key bindings.
Z0k suggested an alternative HELP screen that shows the items and
powerups available in the game. More discussion can be seen in this
thread: http://www.doomworld.com/vb/freedoom/69458-help/
Decompose the help screen into three parts: the background, the
text and the title. Generate all except the main text programatically:
the background as a color transformed version of the INTERPIC graphic
and the title using the textgen tool.
Some build targets create multiple outputs, which can cause problems
when doing parallel builds. Clean up the build system so that all
subdir invocations come from the top-level Makefile and use $(MAKE).
Also fix the FREEDOOM/FREEDM lumps to really include the version
number by using $(shell ...) syntax.
Remove the big text graphic images used for the menus and the
intermission screen. Instead, generate these graphics programatically
from a script. This allows them to be easily changed and extended
as desired.
