Documentation

try_several_IO :: [IO a] -> IO a Source #

Sequentially try one or more IO computations, until one of them completes without an IO error. If all of them fail, re-throw the error from the last one.

system_pdf_viewer :: Double -> String -> IO () Source #

system_pdf_viewer zoom pdffile: Call a system-specific PDF viewer on pdffile file. The zoom argument is out of 100 and may or may not be ignored by the viewer.

windows_pdf_viewer :: Double -> String -> IO () Source #

Like system_pdf_viewer, but specialized to Windows.

macos_pdf_viewer :: Double -> String -> IO () Source #

Like system_pdf_viewer, but specialized to Mac OS.

linux_pdf_viewer :: Double -> String -> IO () Source #

Like system_pdf_viewer, but specialized to Linux.
