1 Introduction
══════════════

  Tinmop is an opinionated client for [gemini protocol], Gopher,
  [Pleroma] (using the mastodon API) and [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".

[Pleroma] <https://pleroma.social/>

[kamid] <https://kamid.omarpolo.com/>


2 Peculiar Features
═══════════════════

  • tree structure of messages;
  • subscriptions of hashtag;
  • programmable and extensible;
  • encrypted direct message (but see 11);
  • 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.


2.1 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] See section 12


3 Dependency
════════════

3.1 Programs
────────────

  ⁃ to build the package: xgettext.

  ⁃ to install the package, including running the script to install lisp
    libraries (`quick_quicklisp.sh'):
    • AWK;
    • git.

  ⁃ to run the program:
    • SBCL compiler;
    • xdg-open;
    • openssl;
    • unzip (command line utitlity 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).


3.2 Lisp Libraries
──────────────────

  • alexandria;
  • cl-ppcre-unicode;
  • tooter;
  • croatoan;
  • osicat;
  • cl-spark;
  • access;
  • sqlite;
  • sxql;
  • sxql-composer;
  • marshal;
  • bordeaux-threads;

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


3.3 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:

    ┌────
    │ # apt-get install libssl-dev
    └────


3.4 Foreign (TCL language) library
──────────────────────────────────

  • tkimg

    ┌────
    │ # apt-get install libtk-img
    └────


4 Install
═════════

4.1 Using guix
──────────────

  Using [guix] is the simpler way to install this software:

  ┌────
  │ $ guix pull && guix package -u && guix install tinmop
  └────

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

  ┌────
  │ $ apt-get install guix
  └────

  or using a shell script [as explained in the guix manual].


[guix] <https://guix.gnu.org/>

[as explained in the guix manual]
<https://guix.gnu.org/manual/en/guix.html#Binary-Installation>


4.2 From source
───────────────

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

     ┌────
     │ $ autoreconf -fiv
     └────

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

     ┌────
     │ $ ./configure
     └────

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

     ┌────
     │ $ ./quick_quicklisp.sh
     └────

     This step is optional if you have already installed quicklisp, in
     this case just load the [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.
     ┌────
     │ $ cd $HOME/quicklisp/local-projects/
     │ $ git clone https://github.com/McParen/croatoan.git
     └────

  5. build the executable:

     ┌────
     │ $ make
     └────

  6. install on your system:

     ┌────
     │ # make install
     └────

  7. take a look the manpage:

     ┌────
     │ $ man tinmop
     └────

  8. run the software!

     ┌────
     │ $ tinmop
     └────

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

5 Usage
═══════

  See the command line options:

  ┌────
  │ $ tinmop -h
  └────

  To get instruction about configuration:

  ┌────
  │ $ man tinmop
  └────

11 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 :
    ┌────
    │ # 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
    └────

    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 [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 [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.

13 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.
