Function Documentation

mutt_comp_init()

void mutt_comp_init

(

void

)

Setup feature commands.

Definition at line 91 of file compress.c.

{
  commands_register(CompCommands, mutt_array_size(CompCommands));
}

Here is the call graph for this function:

Here is the caller graph for this function:

mutt_comp_can_append()

bool mutt_comp_can_append

(

struct Mailbox *

m

)

Can we append to this path?

Parameters

m

Mailbox

Return values

true	Yes, we can append to the file
false	No, 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.

Definition at line 365 of file compress.c.

{
  if (!m)
    return false;
 
  /* If this succeeds, we know there's an open-hook */
  struct CompressInfo *ci = set_compress_info(m);
  if (!ci)
    return false;
 
  /* We have an open-hook, so to append we need an append-hook,
   * or a close-hook. */
  if (ci->cmd_append || ci->cmd_close)
    return true;
 
  mutt_error(_("Can't append without an append-hook or close-hook : %s"), mailbox_path(m));
  return false;
}

Here is the caller graph for this function:

mutt_comp_can_read()

bool mutt_comp_can_read

(

const char *

path

)

Can we read from this file?

Parameters

path	Pathname of file to be tested

Return values

true	Yes, we can read the file
false	No, 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.

Definition at line 394 of file compress.c.

{
  if (!path)
    return false;
 
  if (mutt_find_hook(MUTT_OPEN_HOOK, path))
    return true;
 
  return false;
}

Here is the call graph for this function:

Here is the caller graph for this function:

mutt_comp_valid_command()

int mutt_comp_valid_command

(

const char *

cmd

)

Is this command string allowed?

Parameters

cmd	Command string

Return values

1	Valid 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.

Definition at line 414 of file compress.c.

{
  if (!cmd)
    return 0;
 
  return strstr(cmd, "%f") && strstr(cmd, "%t");
}
