* Introduction

  Tinmop        is       an        opinionated       client        for
  [[https://pleroma.social/][Pleroma]]  (using the  mastodon API)  and
  [[https://gemini.circumlunar.space/][gemini protocol]].   It offer a
  distraction free terminal interface.

  The name is a recursive acronym:  "Tinmop Is Not Mutt or Pine".  The
  older of us can remember that, in turn, Pine is sometimes considered
  an  acronym as  well:  "Pine Is  Not Elm"  and,  finally, Elm  means
  (according to Wikipedia): "Electronic Mail".

* Peculiar Features

  - tree structure of messages;
  - subscriptions of hashtag;
  - programmable and extensible;
  - encrypted direct message (but see [[FAQ]]);
  - no mentions notification, no knowledge of when or who favourited
    your status;
  - No blocking or muting, the client can be configured to ignore
    a list of accounts.

** Important note

   This  is  alpha quality  software,  many  things are  broken,  some
   feature  are missing  some  works  with unintended/unexpected  side
   effects; this software is for  testing only and remember that there
   is [[NO WARRANTY][NO WARRANTY]].

* Dependency

** Programs

   + to build the package:
     xgettext;
     a C compiler.

   + to install  the package, including running the  script to install
     lisp libraries (~quick_quicklisp.sh~):
     - GNU AWK (Gawk);
     - BASH shell.

   + to run the program:
     - SBCL compiler;
     - xdg-open;
     - your favourite editor (default: nano).

All  the dependencies  above  should be  available  using the  package
manager of your distribution (~apt~, ~yum~ etc).

** Lisp Libraries

   - alexandria;
   - cl-ppcre;
   - tooter;
   - croatoan;
   - osicat;
   - cl-spark;
   - access;
   - sqlite;
   - sxql;
   - sxql-composer;
   - marshal;
   - bordeaux-threads;
   - log4cl;
   - local-time;
   - cl-colors2;
   - cl-i18n;
   - clunit2;
   - esrap;
   - ieee-floats;
   - parse-number;
   - cl-html5-parser;
   - unix-opts;
   - crypto-shortcuts;
   - drakma.

   All these libraries  will be downloaded, compiled  and installed by
   the script ~quick_quicklisp.sh~, see below.

** Foreign (C language) library

   - libssl  (TLS socket)
   - linidn2 (i18n domain name aka idna)

     The  C library  should  be installed  with  their header  (~*.h~)
     files.  On Debian  or derived  system this  means installing  the
     library package with the ~-dev~ suffix as shown below:

     #+BEGIN_SRC sh
     # apt-get install libssl-dev libidn2-dev
     #+END_SRC


* Install

  1. optional step needed only if  you have not already the configure script,
     you will need ~autotools~ for that.

     #+BEGIN_SRC sh
     $ autoreconf -fiv
     #+END_SRC

  2. run ~configure~ and resolve the missing dependencies (if any)

     #+BEGIN_SRC sh
     $ ./configure
     #+END_SRC

  3. the script ~quick-quicklisp.sh~ will download and install the library manager and the
     library on your home dir.

     #+BEGIN_SRC sh
     $ ./quick_quicklisp.sh
     #+END_SRC

     This step is optional if you have already installed quicklisp, in
     this case just  load the [[Dependency][dependencies]]
     using  the client installed on your computer.

  4. clone  in ~$HOME/quicklisp/local-projects/~ the latest  version of
     croatoan, a library to wrap the ncurses TUI library.

     This step is temporary as this version will get into quicklisp eventually.
     #+BEGIN_SRC sh
     $ cd $HOME/quicklisp/local-projects/
     $ git clone https://github.com/McParen/croatoan.git
     #+END_SRC

  5. build the executable:

     #+BEGIN_SRC sh
     $ make
     #+END_SRC

  6. install on your system:

     #+BEGIN_SRC sh
     # make install
     #+END_SRC

  7. take a look the manpage:

     #+BEGIN_SRC sh
     $ man tinmop
     #+END_SRC

  8. run the software!

     #+BEGIN_SRC sh
     $ tinmop
     #+END_SRC

  9. An error will be printed about a missing file
     place a simple configuration file in one of the directory the software indicated.
     See [[FAQ][the FAQ below]].

* Usage

  See the command line options:

  #+BEGIN_SRC sh
   $ tinmop -h
  #+END_SRC

  To get instruction about configuration:

  #+BEGIN_SRC sh
   $ man tinmop
  #+END_SRC

* FAQ

  - I just tried to  start the program for the first  time but it give
    me a weird error, what's wrong?

    Did you wrote a configuration file before starting?

    Tinmop  expects  a configuration  file  in  your config  directory
    (usually  ~$HOME/.config/tinmop/~).  This  file  must contains  at
    least  the username  and  the name  of the  instance  you want  to
    connect.

    Example :
    #+BEGIN_SRC text
      # a line starting with a '#' is a comment

      # a file can be included in another with this directive:
      # use "shared.conf"

      # The server instance name
      server = server address

      # your username
      username = username
    #+END_SRC

    If  this file does not  exists or is invalid  tinmop will
    refuse to start.

    Please check the man page (tinmop(1)) for more information.

  - The ~quick_quicklisp.sh~ script failed  and refuse to start again,
    what can I do?

    If tinmop is the first Common lisp program you have ever installed
    installed,  try to  rename the  directory ~$/HOME/quicklisp~  and,
    then, restart the script.

    If problem persists [[BUGS][contact me]].

  - Is tinmop compatible with mastodon servers?

    Unfortunately no, the  way some API endpoint provide  the toots is
    not  suitable for  this client,  for more  information please  go
    [[https://github.com/tootsuite/mastodon/issues/13817][here]].

    I hope  this will change  in the  future but this  depends entirely
    from the people are developing the server.

  - OK the program is running but how can i use it?

    Press the key ~?~ to get a list of the available keys available.

  - Tinmop crashed! Where can i report that?

    The issue tracker is here:

    [[https://notabug.org/tinmop/issues/]]

    Please also,  if possible, send  the backtrace of the  process. To
    print a  backtrace just  write ~backtrace~  when the  debugger has
    been invoked.

    *Important note*

    The  backtrace can  contains sensitive  and personal  information,
    please  always *carefully  checks* the  backtrace contents  before
    making this information public!

  - Are the encrypted messages secure?

    *No*. First only a symmetric  encryption scheme is implemented (so
    there is a problem of secure  key exchanging). Moreover i am not a
    crypto expert and probably i made  something wrong. Note that i am
    not claiming that the algorithm  (AES256) or the implementation of
    such encrypting  algorithm is flawed  but that, likely,  is flawed
    the code i wrote to use the crypto library in this software.

    So, please do not consider the encrypted message secure at all.

* Acknowledgment

  My deep thanks to the folks that provided us with wonderful SBCL and
  Common lisp libraries.

  In particular i want to thanks the authors of the libraries Croatoan
  and Tooter for their help when I started to develop this program.

  There  are more  people  i borrowed  code and  data  from, they  are
  mentioned in the file LINCENSES.org

  This program  is was born  also with  the help of  CCCP: "Collettivo
  Computer Club Palermo".

  Also thanks to "barbar" for testing of the installation scripts.
