No modern development tools support it, most relevantly Apple’s Xcode, which we use to build Texpad. Unfortunately, WEB never caught on, and today it is almost exclusively used by TeX, and related programs such as BibTeX and MetaFont.
TEXPAD CHANGE ENCODING CODE
He did so in WEB, a fascinating programming system that blends Pascal code and documentation to create something in between a computer program and an essay. TeX, the core on which LaTeX is built, was written by Donald Knuth in the 70s. This was an early example for us of how an integrated typesetter could improve a user’s experience with Texpad, but it was difficult to progress due to the way TeX was written. Removing the disk read and write greatly improved the efficiency of the typeset process. We forked KerTeX, a minimal, permissively licensed TeX distribution, to create the first version of TexpadTeX.Īn unintended benefit was that the TexpadTeX typesetter could take its input directly from the editor and output it directly to the viewer. The design of iOS prohibits launching external programs in this way, so when building Texpad iOS we were forced to integrate LaTeX into Texpad. Access times for even the fastest Solid State Drives are substantially slower than reading and writing to a program’s memory, so it slows down the process.

This post is a record of the history and development of TexpadTeX to give you an idea how it works under the hood. The biggest gains have come from integrating the internal TexpadTeX typesetter with the graphics card using Apple’s Metal framework.
Texpad 1.9 on both macOS and iOS runs faster using less memory than the 1.8 series. With iOS capable of replacing a laptop now, we have updated Texpad iOS to take advantage of these new features, and for the first time make it no less capable than its desktop sibling.Īs well as adding new features, in Texpad 1.9 we have also made the old features more efficient. The iOS ecosystem has gained a file management system, more powerful devices, and even keyboard/mouse devices in the last few years. Texpad 1.9 has many changes from the 1.8 series, most notably a reworking of the iOS interface to bring all the features from Texpad macOS to Texpad iOS.
