instead of per-tool-settings.

This is against the standard:
"The application shall ensure that the makefile does not specify
prerequisites for inference rules;"[0]
We are still fine though as we explicitly state the dependency on the
requisite-objects in the $(BIN)-target.
Thanks Lucas for pointing this out!

Thanks Hiltjo for the feedback! GNUisms need to be avoided like a
plague, even if it means having to be a little more creative.
Strict POSIX compliance means that I just worked within the bounds of
the POSIX specification, hopefully without using any GNU or BSD
extensions. If I did, please let me know.
Tip to all Linux users: Test your Makefiles with pmake(1) instead of
make(1) (= GNU make) and refer to the newest POSIX 2016 make
specification[0].

I didn't like the current Makefiles. They were too crufted and not
elegant. Additionally, given I'm planning to put some utility functions
into a util.{c|h}-prerequisite, I wrote this new Makefile with PREREQs
in mind.

Laslo: Minor changes
Signed-off-by: Mattias Andrée <maandree@kth.se>

- fix: rebuild on source change.
- allow to override dependency flag per tool (the ones that have deps).
- rebuild on config.mk or headers change.
|
|
This reverts commit 545c500d4278c50e781c9a5a550e92cb0023c8e8.
|
|
I forgot to add the dependencies in the build process
|
|
Even though I like line-length limits, it imposed a useless limitation
on the console output, given the line input is variable.

- be verbose by default: don't hide the executed commands.
- no need to make clean on make dist, but make sure to have a clean directory.
- define 2ff in ${SCRIPTS}.
- make dist: gzip directly, don't store intermediate step (faster for make dist
on floppies).
- don't cd into directories, just loop each file.
|
|
|
|
- jpg2ff requires libjpeg
- ff2png, png2ff requires libpng (and libz)
- ff2ppm has no dependencies
|
|
ff2ppm can convert farbfeld images to PPM (P6 binary format, 24-bit RGB).
ff2ppm has an option -b to set the background color, for example for png files:
png2ff < test.png | ff2ppm -b '#00ff00' > test.ppm

Thanks Dimitris for reporting this!

And add a makerule to create a tarball via make dist.

Thanks quinq for reporting this!

I forgot that we can't just cd. It has to be a &&-statement.
Also, uncomplicate the output.
|
|
While at it, refactor the makefile a bit.
|
|
Thanks z3bra for porting this!
Also change 2ff to use case instead of if-blocks.
|
|
This is a wrapper for the different conversion utilities with
filetype detection using file(1) and an imagemagick fallback.
|
|
|
|
|
|
- Rename the format
- Change the format specification
- Drop old tools waiting to be fixed on a later date, just keep
fixed png for now
- Simplify other stuff
This is a direct consequence of my slcon2-talk on this topic.
At first I planned to have 64 bits per channel, but this is
overkill.

Thanks to Henrique Lengler <henriqueleng@opmbx.org> for the patch!

Respectively, image.png will become an image.if
