# Local changes to mitex 0.2.5
|
|
|
|
This copy is not stock. mitex is vendored rather than fetched through Typst's package system so
|
|
that an export needs no network, which also means an update is a manual copy and a patch applied
|
|
here is a patch that can be silently lost. Anyone replacing this directory has to re-apply what is
|
|
listed below, or re-check that it is no longer needed.
|
|
|
|
Upstream is https://github.com/mitex-rs/mitex, Apache-2.0, and LICENSE beside this file is theirs.
|
|
|
|
## specs/latex/standard.typ: `\hspace`, `\vspace` and `\raisebox` no longer evaluate their argument
|
|
|
|
Those three handlers passed the text between the braces to `eval`, which runs it as Typst code.
|
|
The text is whatever the author typed, so a markdown file containing
|
|
`$\hspace{range(999999999).len()*1pt}$` is a program rather than a formula. Typst is hermetic, so
|
|
this is not a way to read a file or reach the network, but the compiler runs inside the editor's
|
|
own process: measured, that document took nine gigabytes resident before the process died, and it
|
|
would have taken any unsaved buffer with it.
|
|
|
|
The three handlers now go through `mitex-safe-length`, which evaluates the argument only when it is
|
|
a plain length literal and answers `0pt` otherwise. `src-tauri/tests/pdf.rs` pins both halves.
