Hi Pravin and list,
at sunzi project, we strive to consume external components from
their repositories and other native locations. To make it easily
possible also with Liberation fonts, I went through the existing
Makefile with the aim to add support for exporting into common web
formats, making some other changes on my way.
In fact, the change I desire is concentrated in the last patch, but
I hope the previous ones (split into more patches for easier review)
also make sense. The compatibility with releasing workflow as well
as with the job of system packagers should be guaranteed.
If there is something wrong with the patchset, feel free to bug me
on. Otherwise I would be grateful for applying it.
P.S. I can go ahead and file a bug (referring to this thread) if it is
a preferred channel.
Regards,
Jan

Also fix options to tar command so the symlinks are resolved first.
Note that previously, dist-ttf would propably fail if not dist-sfd
was not run in advance (due to missing "cp ../README ./").

- 1. What's this?
- =================
-
- The Liberation Fonts is font collection which aims to provide document
- layout compatibility as usage of Times New Roman, Arial, Courier New.
-
-
- 2. Requirements
- =================
-
- * fontforge is installed.
- (http://fontforge.sourceforge.net)
-
-
- 3. Install
- ============
-
- 3.1 Decompress tarball
-
- You can extract the files by following command:
-
- $ tar zxvf liberation-fonts-[VERSION].tar.gz
-
- 3.2 Build from the source
-
- Change into directory liberation-fonts-[VERSION]/ and build from sources by
- following commands:
-
- $ cd liberation-fonts-[VERSION]
- $ make
-
- The built font files will be available in 'build' directory.
-
- 3.3 Install to system
-
- For Fedora, you could manually install the fonts by copying the TTFs to
- ~/.fonts for user wide usage, or to /usr/share/fonts/truetype/liberation
- for system-wide availability. Then, run "fc-cache" to let that cached.
-
- For other distributions, please check out corresponding documentation.
-
-
- 4. Usage
- ==========
-
- Simply select preferred liberation font in applications and start using.
-
-
- 5. License
- ============
-
- This font set had been released under GNU Public License version 2
- ("GPLv2") with exceptions.
-
- Please read file "COPYING" for GPLv2 license.
-
- Please read file "License.txt" for details of exceptions.
-
-
- 6. For Maintainers
- ====================
-
- Before packaging a new release based on a new source tarball, you have to
- update the version suffix in the Makefile:
-
- VER = [VERSION]
-
- Make sure that the defined version corresponds to the font software metadata
- which you can check with ftinfo/otfinfo or fontforge itself. It is highly
- recommended that file 'ChangeLog' is updated to reflect changes.
-
- Create a tarball with the following command:
-
- $ make dist
-
- The new versioned tarball will be available in the dist/ folder as
- 'liberation-fonts-[NEW_VERSION].tar.gz'.
-
- 7. Credits
- ============
-
- Please read file "AUTHORS" for list of contributors.

New subject: [PATCH 4/6] Makefile: add check target using fontlint
Fontlint is a font checker accompanying FontForge.
The check will proceed the SFD files through it, outputting the messages
to both standard output and to the per commit specific file (failback
to per date specific if git information not available) for easy
regression checking. This final part of "check" workflow can be done,
e.g., manually (with diff selecting the right files to compare).
To prevent logs from check messing the repo, capture them in local
.gitignore file that initially includes also archives and directory
with generated TTF files.

New subject: [PATCH 5/6] Makefile: restructure for usability and modularity
Previously, it was rather a shell script than set of recipes
with resource dependencies tracking.
The old targets (should) work as they used to, plus there are new ones:
- make ttf:
generate TTF files in the "export" dir (which can be overriden from
command line), utilizing native feature of "make" to generate only
files the sources of which have changed (useful, e.g., for continuous
updates tracking)
- make ttf-dir:
target which "make" and "make down" boil down to, single-shot
batch generation of TTF file to dedicated directory, i.e., without
the advantage of dependency-change tracking as with the previous
To handle more universal tasks, new FontForge script was added
as scripts/fontexport.pe (it even contains brief help) and is
integrated on the places as the other ones.
Also .gitignore is extended with "export" dir.

New subject: [PATCH 6/6] Makefile: now support other common export formats
Based on the previous patch, we create a generalization of how was
"ttf" target handled to support exporting also to other common
formats. We add "4web" target covering common formats used on
the web (HTML/CSS:font-face): TTF, WOFF, SVG, EOT.
It is easy to add other formats if needed and provided that
such format is supported by FontForge.
To be honest, I am not sure about two things:
- Is the existing TTF export OK for web usage? Have been exploring
this field shortly, but cannot defuse my confusion (TTF/OTF, ...).
- Is hardcoded "fmflags" parameter in scripts/fontexport.pe
OK also for formats other than TTF?

Yes. It should work fine.

Will be good if you can test it and update the thread, so before final
commit i will be in better position.

I've put together a simple test page [1] so anyone can test the result
in the browser of choice. I've only tested Firefox (i.e., TTF and WOFF
only) and works as expected. All the formats used are generated using
"make 4web", employing the proposed patchset.
Pravin, we can somehow get such or similar test HTML to the upstream
repo if preferred (can be viewed offline as well, indeed).

I've put together a simple test page [1] so anyone can test the result
in the browser of choice. I've only tested Firefox (i.e., TTF and WOFF
only) and works as expected. All the formats used are generated using
"make 4web", employing the proposed patchset.
Pravin, we can somehow get such or similar test HTML to the upstream
repo if preferred (can be viewed offline as well, indeed).
Yes, having test page in upstream repo is good idea.
I will check and commit in upstream repo, soon.
Thanks,
Pravin Satpute

New subject: [PATCH 6v2/6] Makefile: now support other common export formats (v2)
Based on the previous patch, we create a generalization of how was
"ttf" target handled to support exporting also to other common
formats. We add "4web" target covering common formats used on
the web (HTML/CSS:font-face): TTF, WOFF, SVG, EOT.
It is easy to add other formats if needed and provided that
such format is supported by FontForge.
Update v2
---------
EOT is not supported natively by FontForge, so in fact, another tool
is needed, either will serve the purpose:
1. mkeot from eot-utils (http://www.w3.org/Tools/eot-utils/)
2. ttf2eot (http://code.google.com/p/ttf2eot/)
Unfortunately, these are not commonly packaged so they have to be
compiled from source. This is quite straightforward, only in case 2.,
extra header file has to be imported, see [1].
The Makefile supports both these convertors. I made some comparison
of the two and the output is similar, although 2. seems to be doing font
subsetting and supports setting the URL prefixes where the font is
intended to be used -- this can be explictly requested using:
make eot MKEOT_URLS="URL1 URL2 ..."
Because 1. is also under the wings of authoritative organization (W3C),
I arranged it as prioritized choice with the fallback to 2. if mkeot
is not found on the PATH (if even this is missing, the eot target fails).
If official distribution of web fonts incl. EOT is ever to be made,
I think it is important to mark (in the form of a comment in Makefile)
the "canonical" converter. I anticipated it is 1. as well, but it can be
changed anytime (preferrably also fallback order is changed then).
In scripts/fontexport.pe, printing newline is removed.

Update v3
---------
Use "libre roots" by default for EOT as it seems that 1+ root is needed
for MSIE 8+ and these are as neutral as possible (see also test page
[2]).
Also, make should be more parallel-run-friendly now regarding creation
of export dir.
