Glyph Bitmap Distribution Format is no more, as the creators of Pango, one of the most widely used text rendering libraries, announced their plans for Pango 1.44.

Until recently, Pango used FreeType to draw fonts. They will be moving over to Harfbuzz, an evolution of FreeType.

Why?

In short, FreeType was hard to work with. It required complex logic, and provided no advantage over Harfbuzz (other than being able to fetch opentype metrics with ease).

Upgrading to Pango v1.44 will break your GTK applications (if you use a bdf/pcf bitmap font). Harfbuzz does support bitmap-only OpenType fonts, otbs. Convert your existing fonts over to otbs using FontForge. It is to be noted that applications such as xterm and rxvt use xft (X FreeType) to render fonts, and will remain unaffected by the update.

Both scientifica and curie will soon ship with bitmap-only OpenType font formats.

This piece aims to highlight (pun intended) some of the reasons behind my color free editor setup.

Imagine highlighting an entire book because all of it is important. That is exactly what (most) syntax highlighting does. It is difficult for the human eye to filter out noise in rainbow barf. Use color to draw attention, not diverge it.

At the same time, a book devoid of color is boring! What is the takeaway from this 10 line paragraph? What are the technical terms used?

Prose and code are certainly different, but the fickle minded human eye is the same. The eye constantly looks for a frame of reference, a focal point. It grows tired when it can’t find one.

@@ -65,13 +46,15 @@

Without highlighting (far left), it is hard to differentiate between comments and code! The florid color scheme (far right) is no good either, it contains too many attention grabbers. The center sample is a healthy balance of both. Function calls and constants stand out, and repetitive keywords and other noise (let, as) are mildly dimmed out. Comments and non-code text (sign column, status text) are dimmed further.

I’ll stop myself before I rant about color contrast and combinations.

My entire setup is managed with GNU stow, making it easier to replicate on fresh installations. You can find my configuration files on GitHub.

I run Void Linux (glibc) on my HP Envy 13" (2018). To keep things simple, I run a raw X session with 2bwm as my window manager, along with dunst (notification daemon) and Sam’s compton (compositor) fork.

I am a fan of GNU tools, so I use bash as my shell, and coreutils to manage files, archives, strings, paths etc. I edit files with vim, chat with weechat, listen to music with cmus, monitor processes with htop, manage sessions with tmux, read pdfs in zathura. I rarely ever leave the comfort of my terminal emulator, urxvt.

Most of my academic typesetting is done with TeX, and compiled with xelatex. Other fun documents are made with GIMP :).

Onivim is a ‘modern modal editor’, combining fancy interface and language features with vim-style modal editing. What’s wrong you ask?

Apart from buggy syntax highlighting, broken scrolling and others, Onivim is proprietary software. It is licensed under a commercial end user agreement license, which prohibits redistribution in both object code and source code formats.

Onivim’s core editor logic (bits that belong to vim), have been separated from the interface, into libvim. libvim is licensed under MIT, which means, this ‘extension’ of vim is perfectly in adherence to vim’s license text! Outrun Labs are exploiting this loophole (distributing vim as a library) to commercialize Onivim.

Onivim’s source code is available on GitHub. They do mention that the source code trickles down to the oni2-mit repository, which (not yet) contains MIT-licensed code, 18 months after each commit to the original repository.

Want to contribute to Onivim? Don’t. They make a profit out of your contributions. Currently, Onivim is priced at $19.99, ‘pre-alpha’ pricing which is 80% off the final price! If you are on the lookout for an editor, I would suggest using Vim, charity ware that actually works, and costs $100 lesser.
