This takes a string that is then split upon like `string split`.
Unlike $IFS, the string is used as one piece, not a set of characters.
There is still a fallback to IFS if no delimiter is given, that
behaves exactly as before.
Fixes#4156.
The `read` command `-m` and `--mode-name` vars are now deprecated and do
nothing other than result in a warning message. The `read` command now
honors the `FISH_HISTORY` var that is used to control where commands are
read from and written to. You can set that var to the empty string to
suppress the use of both history files. Or you can set it to a history
session ID in which case that will limit the `read` history that is
available.
Fixes#1504
This puts a hard upper bound of 10 MiB on the amount of data that read
will consume. This is to avoid having the shell consume an unreasonable
amount of memory, possibly causing the system to enter a OOM condition,
if the user does something non-sensical.
Fixes#3712
The `--null` flag to `read` makes it split incoming lines on NUL instead
of newlines. This is intended for processing the output of a command
that uses NUL separators (such as `find -print0`).
Fixes#1694.
Rework for Doxygen >1.8. Moved large parts of the documentation to a
simplified format, making use of Markdown enhancements and fixing bad
long options.
Enhance the `read` builtin to support creating an array with the --array
flag. With --array, only a single variable name is allowed and the
entire input is tokenized and placed into that variable as an array.
Also add custom behavior if IFS is empty or unset. In that event, split
the input on every character, instead of the previous behavior of doing
no splitting at all.
Large list of changes, including formatting and typos for most commands.
More substantive changes have been made to alias, bind, block, break,
builtin, case, cd, commandline, count, else, emit, fish_config, funced,
function, functions, history, math, mimedb, nextd, not, popd, prevd,
pushd, pwd, random, read, set, set_color, switch, test, trap, type,
ulimit, umask, and while.
Fish now doesn't join the fish_prompt output. This breaks the default
fish_prompt. Make default fish_prompt single-line. Fixes#203.
Add -l flag to 'read' documentation. Remove ambiguous '-x' description.
Fixes#157.
