◆ mutt_comp_can_append()

bool mutt_comp_can_append ( struct Mailbox m)

Can we append to this path?

Parameters
mMailbox
Return values
trueYes, we can append to the file
falseNo, appending isn't possible

To append to a file we can either use an 'append-hook' or a combination of 'open-hook' and 'close-hook'.

A match means it's our responsibility to append to the file.

◆ mutt_comp_can_read()

bool mutt_comp_can_read ( const char *  path)

Can we read from this file?

Parameters
pathPathname of file to be tested
Return values
trueYes, we can read the file
falseNo, we can't read the file

Search for an 'open-hook' with a regex that matches the path.

A match means it's our responsibility to open the file.

◆ mutt_comp_valid_command()

int mutt_comp_valid_command ( const char *  cmd)

Is this command string allowed?

Parameters
cmdCommand string
Return values
1Valid command
0"%f" and/or "%t" is missing

A valid command string must have both "%f" (from file) and "%t" (to file). We don't check if we can actually run the command.
