1. Pass them as arguments when running the program; e.g., `h-m-m --focus-lock=true --line-spacing=0 filename`
1. Set them as environment variables with `hmm_` as prefix; e.g., `hmm_line_spacing=0`
1. Store them in a config file. You can pass the location of the config file when running the application like `h-m-m --config=/path/file`, or use the default location:
* Linux: ~/.config/h-m-m/h-m-m.conf
* Mac: ~/Library/Preferences/h-m-m/h-m-m.conf
* Windows: an h-m-m.conf file in the same directory as the script
Both underscores and dashes are accepted for the setting keys.
*`--clipboard=command` uses `--clipboard_in_command="command %text%"` to send content to a shell command and `--clipboard_out_command="command"` to read content.
You can export an HTML version of the map using the `x` key binding. This is useful for sending the file to someone who may not have h-m-m or a similar mind mapping application. To make the process easier, you can set a sell command to run after exporting the map; e.g., upload it to a server and copy the link to clipboard: `--post-export-command="upload.sh %filename% &>/dev/null"`.
Mind maps are stored in plain text files (with `hmm` file extension by default) without metadata. The tree structure is represented by tab indentations; e.g.,
root (level 0)
item A (level 1)
item B (level 1)
item Ba (level 2)
item Bb (level 2)
item Bc (level 2)
item BaX (level 3)
item BaY (level 3)
item Bd (level 2)
item C (level 1)
When you yank (copy) or delete (cut) a subtree, the data will be put into your clipboard with a similar structure, and when pasting, the data will be interpreted as such.
Most mind mapping applications use a similar format for copying and pasting. As a result, if you want to import a map from another application, you can probably select everything in that application, copy it, come to **h-m-m**, and paste it. The same usually works well when copying from HTML/PDF/Doc lists, spreadsheets (e.g., Calc and Excel), etc.
Note: A few issues should be solved before **h-m-m** can be run in Windows. Until then, Windows users can probably use *Windows Subsystem for Linux* to run it. There's an [open issue](https://github.com/nadrad/h-m-m/issues/29) for Windows, waiting for contributors!
**h-m-m** is a single php file. You can download it from here, or clone it on your computer using git and add a scheduled job to update it once a day or week.
You also need to have the following installed for h-m-m to work:
* php
* either php 8, or
* older versions of php along with the `mbstring` package (e.g., `php7.2-mbstring`)
After downloading or cloning, you can run `php h-m-m` in your terminal to run the program with a blank map or `php h-m-m filename` to open an existing file. If you don't already have a php interpreter installed, you would need to install it as well. Note: You don't need to set up a "web server" to run it because it's not a web application, but rather a terminal application that works like those written in Python, Bash, etc.
Optionally, you can make the file executable by running the `chmod +x h-m-m` in your terminal, and afterward, you can run it as `h-m-m filename` (assuming that **h-m-m** is in your path).
This command downloads and runs the install.sh script, which it turn downloads h-m-m, copies it to `/usr/local/bin`, checks the dependencies, and makes it executable.
After installing, you can run `h-m-m` from anywhere in your terminal to run the application with an empty map, or `h-m-m filename` to open an existing file.
Programming is not my career, but rather a hobby, and I developed **h-m-m** because I wanted to have something like this application and couldn't find one. Therefore, what I've done here may have a lot of room for improvement. If you see an embarrassing problem in the program or have an idea for improvement, feel free to contact me; I'd be happy to receive your feedback.
Why php? It's simple: I only have a rusty knowledge of Pascal and a little familiarity with php. I thought about learning another language for this project (Nim is my top choice at this moment), but I didn't have time to do it. I'll probably do it later and convert it into a language I can compile :)
