Captain's Log - or `Caps-Log` for Short

Caps-Log is a small, terminal-based journaling tool.

What It Does

Daily entries are saved locally as Markdown files. Level 1 headers are interpreted as 'sections', and unordered lists beginning with the '*' character are interpreted as 'tags'. Titles of these sections and tags are then displayed in two menus. When selecting a section, tag menu will list out only the tags found under the selected section. If no section is selected, tag menu will display all tags found. Selecting an item in these menus highlights the dates with mentions of that tag or title in the calendar. This feature provides a visual representation of how (in)consistent your habits and activities are.

Clicking on a date or pressing enter when a date is focused will open that log file in an editor, if possible. Currently, Caps-Log uses your $EDITOR environment variable to start the editor, if set. Otherwise, this functionality is disabled. This integration looks particularly impressive with terminal-based editors.

Additionaly, caps-log also has a primitive 'remote storage' feture in the form of using a git repository with a remote to push and pull data. (See Configuration & Command Line Options section below)

Note

Emoji handling is somewhat erratic, potentially due to an FTXUI issue or misuse on my part. This could also be an issue with my font or terminal emulator. When an emoji is drawn, it shifts all other characters to the right by one place.
The tool is not optimal for use in small terminals. While still functional, it performs best when the entire calendar is visible.

Getting It

It is recomended that you build and install it manualy, see Building and installing section.

Or you can visit the releases page and download a caps-log-<platform>.tar.gz file that contains a prebuilt binary, but for now only x86 Linux and intel MacOS platfroms are supported. This will be improved in the future.

Keybindings

Tab or Shift + Tab = Switch focus between the calendar and menus.
h or arrow keys = Navigate within the calendar or menus.
Enter = Highlight logs containing a specific tag/section or open the log entry in $EDITOR for the date under the cursor.
D = Delete the log under the cursor if the calendar is focused.
+ / - = Navigate to the next / previous year's calendar.

Log Entry Tags and Sections

Caps-Log stores all logs as simple Markdown files to enable syntax highlighting in your editor. This 'syntax' was chosen based on personal preference. If you find flaws, please open an issue. It's up to you to decide what constitutes a section and what a tag.

Sections

To mark a section, use: # Section Name. All text below until the next section is considered part of it. By default, the first line of the file is ignored when identifying section titles, as it's commonly used for the date of the entry. This behavior can be configured via command line arguments or a config file.

Tags

Tags can be added to the log entry by starting a line with * Tag Name. Tags can belong to a section, but they don't have to. If they don't belong to a section, they are considered to belong under a <root section> which is displayed in the section menu.

* Tag Name
* Tag Name (Additional Information)
* Tag Name (Additional Information): A multiline body that is ignored by Caps-Log For examples of valid and invalid sections and tags, see ./test/log_entry_test.cpp

Encrypting Logs

Caps-Log can encrypt your logs using the AES encryption algorithm. If you open an encrypted log repo, you will be prompted to enter a password. In case you enter a wrong password, caps-log will notify you end exit. Same if you provide a password for a non encrypted log repository.

# Note: Caps-Log will ignore files not matching the log filename format.
# You can also provide --log-dir-path and --log-filename-format to control behavior.
# Encrypt
caps-log --encrypt --password <your password>
# Decrypt
caps-log --decrypt --password <your password>

Configuration & Command Line Options

Command Line Options

Allowed options:
  -h [ --help ]                         Show this message.

                                        (~/.caps-log/config.ini).
  --log-dir-path arg (=~/.caps-log/day/)
                                        Path where log files are stored.

                                        first line, override the default
                                        behavior of ignoring it.
  --password arg                        Password for encrypted log repositories
                                        or to be used with --encrypt/--decrypt.

                                        directory path (requires --password).
  --decrypt                             Apply decryption to all logs in the log
                                        directory path (requires --password).

Config File

most of the command line flags can be set through a config file.

log-dir-path=/path/to/log/dir
log-name-format=%y_%d_%m.txt
sunday-start=true
first-line-section=true
password=your-password

Config file also allows configuring caps-log to treat the directory where logs are stored as a git repository with a remote set-up. Upon exiting, caps-log will commit and push all changes to the remote. Note that currently, only the remotes with ssh authentication are supported. Here is an example of a config file for git remote log repository.

# NOTE: this must be a path to a directory that is 
# inside the git.repo-root, otherwise `caps-log` will fail to start.
log-dir-path=/Users/me/.caps-log/clog-entries/days

[git]
# setting it to false, or not setting it at all is the 
# same as not having the below options defined
enable-git-log-repo=true 
ssh-key-path=/Users/me/.ssh/id_rsa # required
ssh-pub-key-path=/Users/me/.ssh/id_rsa.pub # required
repo-root=/Users/me/.caps-log/clog-entries/
remote-name=something # 'origin' is the default
main-branch-name=main # 'master' is the default

Annual events Caps-log can also be configured to display annual events in the calendar. They will be highlighted with green color and number of days since or until the event (if the total number of days is less that recent-events-window days) will be displayed in the small box to the left of the calendar.

[calendar-events]
recent-events-window=60

[calendar-events.birthadays.0]
name=Joe
date=18.07
[calendar-events.birthadays.1]
name=Jane
date=03.07.
[calendar-events.holidays.0]
name=New Years eve
date=01.01.
[calendar-events.holidays.1]
name=New Year
date=31.12.

Building & Installing

Dependencies

Caps-Log fetches its dependencies from GitHub, except for Boost and libgit2. You should have Boost program options installed. This typically involves:

# Linux
sudo apt-get install -y libboost-program-options-dev libgit2-dev
# Mac
brew install boost libgit2

To build the Caps-Log executable, run:

mkdir build && cd build && cmake ..
make

After a successful build, to install the executable in a common $PATH location, run: sudo make install. Then, you can simply start the application by typing caps-log in your terminal.

If you wish to build and run the tests, execute:

mkdir build && cd build && cmake .. -DCAPS_LOG_BUILD_TESTS=ON
make 
ctest
