* Introduction

  Tinmop is an opinionated client for [[https://gemini.circumlunar.space/][gemini protocol]], Gopher,
  [[https://joinmastodon.org/][Mastodon]], [[https://pleroma.social/][Pleroma]] (using the mastodon API) and [[https://kamid.omarpolo.com/][kamid]] protocols. It offer a
  distraction free terminal interface and a GUI for connecting to the geminispace.

  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:
     - C compiler
     - SBCL compiler;
     - curl
     - xgettext.

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

   + to run the program:
     - xdg-open;
     - openssl;
     - unzip (command line utility to decompress zip file);
     - TK wish interpreter;
     - your favourite editor (default: nano).

   + optional recommended programs:
     - man
     - imagemagick

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

** Lisp Libraries

   - access;
   - alexandria;
   - babel;
   - bordeaux-threads;
   - cl+ssl;
   - cl-base64;
   - cl-colors2;
   - cl-html5-parser;
   - cl-i18n;
   - cl-ppcre-unicode;
   - cl-spark;
   - clunit2;
   - croatoan;
   - crypto-shortcuts;
   - drakma;
   - esrap;
   - flexi-streams;
   - ieee-floats;
   - local-time;
   - log4cl;
   - marshal;
   - nodgui;
   - parse-number;
   - percent-encoding;
   - purgatory;
   - sqlite;
   - sxql;
   - sxql-composer;
   - tooter;
   - trivial-clipboard;
   - uiop;
   - unix-opts;
   - usocket;
   - yason.

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

** Foreign (C language) library

   - libssl  (TLS socket)

     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
     #+END_SRC

*** Indirect foreign dependencies

These library are not directly required by tinmop, but are needed nevertheless to make the GUI library ([[https://www.autistici.org/interzona/nodgui.html][nodgui]]) works.

     #+BEGIN_SRC sh
     # apt-get install tk libturbojpeg0-dev
     #+END_SRC

Note that, at the moment, the ~quick_quicklisp.sh~ script will *not* install the foreign dependencies.

* Install

** Using guix

   Using [[https://guix.gnu.org/][guix]] is the simpler way to install this software:

   #+BEGIN_SRC sh
   $ guix pull && guix package -u && guix install tinmop
   #+END_SRC

   Guix can be installed on debian (testing or sid):

   #+BEGIN_SRC sh
   $ apt-get install guix
   #+END_SRC

   or using a shell script [[https://guix.gnu.org/manual/en/guix.html#Binary-Installation][as explained in the guix manual]].

** From source
  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 lisp libraries 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. optional step if you did not ran ~quick-quicklisp.sh~.

     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://codeberg.org/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

  But, please, take a minute to read the file [[./CONTRIBUTING.org]] before

* 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 could be used just as a gemini client.
    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?

    Yes, in fact I am using tinmop with a Mastodon istance on a daily basis.

  - 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://codeberg.org/cage/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 LICENSES.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.
