-- Tests for autocommands

-- - FileWritePre writing a compressed file
|
|
-- - FileReadPost reading a compressed file
|
|
-- - BufNewFile reading a file template
|
|
-- - BufReadPre decompressing the file to be read
|
|
-- - FilterReadPre substituting characters in the temp file
|
|
-- - FilterReadPost substituting characters after filtering
|
|
-- - FileReadPre set options for decompression
|
|
-- - FileReadPost decompress the file
|

-- Note: This test is skipped if "gzip" is not available.

-- $GZIP is made empty, "-v" would cause trouble.
|

-- Use a FileChangedShell autocommand to avoid a prompt for "Xtestfile.gz"
|

-- being modified outside of Vim (noticed on Solaris).
