F.6.2.6 Standard Errors

This is a list of the more important error symbols in standard Emacs. The list includes each symbol’s message.

error

"error"

quit

"Quit"; note that the error symbol ‘quit’ does not have the condition ‘error’, because quitting is not considered an error.

args-out-of-range

"Args out of range"

arith-error

"Arithmetic error"

beginning-of-buffer

"Beginning of buffer"

buffer-read-only

"Buffer is read-only"

circular-list

"List contains a loop"

cl-assertion-failed

"Assertion failed"

coding-system-error

"Invalid coding system"

cyclic-function-indirection

"Symbol’s chain of function indirections contains a loop"

cyclic-variable-indirection

"Symbol’s chain of variable indirections contains a loop"

dbus-error

"D-Bus error"

end-of-buffer

"End of buffer"

end-of-file

"End of file during parsing"; note that it pertains to the Lisp reader, not to file I/O.

file-already-exists

a subcategory of= file-error=

file-date-error

a subcategory of ‘file-error’; it occurs when copy-file tries and fails to set the last-modification time of the output file.

file-error

We do not list the error-strings of this error and its subcategories, because the error message is normally constructed from the ‘DATA’ items alone when the error condition ‘file-error’ is present. Thus, the error-strings are not very relevant.

file-missing

a subcategory of ‘file-error’;

compression-error

a subcategory of ‘file-error’;

file-locked

a subcategory of ‘file-error’;

file-supersession

a subcategory of ‘file-error’;

"Invalid regexp"

text-read-only

"Text is read-only"; a subcategory of ‘buffer-read-only’;

undefined-color

user-search-failed

This is like ‘search-failed’, but doesn’t trigger the debugger, like ‘user-error’.
