Looks like it did work.
Would adding a trailing quote work?

WARNING: the project is still in its early stages so do expect bugs and incomplete features, if you encounter them or would like to suggest an improvement, feel free to submit to the ticket tracker on srht or the one on github.

I plan to set up automated uploads of pre-built binaries to each release at some point in the future.

As of now you can either build from source or use go install.

#With go install

go install git.sr.ht/~hedy/gelim@latest

All set! Skip to usage

Note that this method does not provide version information

#Build from source

First, install the dependencies:

  • go (I think >=1.16)
  • scdoc (for building manpage)

Clone the repo somewhere reasonable:

git clone https://git.sr.ht/~hedy/gelim
cd gelim
# Recommended to use latest pinned version, rather than @latest
# git checkout v0.0.0

Build, optionally set PREFIX (default is PREFIX=/usr/local):


If all goes well, install gelim.

Remember to use the same PREFIX too.

sudo make install

# Or without sudo:
# $ make PREFIX=~/.local install

If you don't want to build the manual, you may put your hacker hat on, dive into the Makefile, and copy the go build command used to compile gelim. This lets you store version info accessible at --version.

Or you know what? Just a go build works too! The resulting binary will be in the current directory.

Optionally verify your installation:

make checkinstall

The gelim binary would be sitting at $PREFIX/bin/ with manpage at $PREFIX/share/man/ :)


  • "scdoc: command not found":

    Make sure scdoc is installed before building. Or you can skip building the manpage and just run go build instead. Check the Makefile for reference.

  • Something to do with io.ReadAll:

    Gelim requires go version >= 1.16.

If you're having other issues with installation, please send an email to the mailing list with errors/logs if available.


If you used the Makefile to install gelim the manpage should automatically be built and installed. See gelim(1)

I'm also planning to have a mirror of that manual hosted on man.sr.ht in the future for easy access.

Note that the manpage may not be the most recently updated. But new features and things like that will definitely be put in there once it's tested stable.


gelim gemini.circumlunar.space

This will bring you to less(1). You can use less to browse the page normally.

Note: if you see something like "-P is not an option", don't panic, this is because your system does not support one of gelim's default less options, you should skip over to the 'config' section below, and configure your lessOpts to remove the -P option, and any other your version of less doesn't have.

When you want to visit a link, you have to quit less first. Press q

The page will be fetched and you'll be in less again.

Now let's try something more interesting.

While you're at the prompt type:


Say you don't have an account on RTC yet and would like to sign up.

Go to the bottom of the page, where the link to signing up is provided. Type G

Then, you have to quit the pager. Press q

Look for the link number that links to the sign up page, and enter it directly at the prompt. As of writing, the link number is 38, but keep in mind this number may change when you are trying this out.


And now you've decided to have a look at rawtext.club's values at the front page on more time. Unfortunately, the sign up page does not provide a link to go back to home. No worries, you can directly use the path (prefixed with . or /) at the prompt.

Let's try it out. Quit the pager (q), and type / and press enter

Voila, you're at the front page again!

Thanks for trying out this quickstart tutorial, there is still much to explore. Type in help from the prompt and check out the commands, have fun!

Everything in page rendering is handled with less(1). less is called with opptions specified from your config file. gelim has no intervention in pre-processing any keys.

Hence, anything that works in less should work normally when less is called by gelim.

Useful navigation keys include: d/u/PgDn/PgUp/Space.

Useful keys for jumping to positions include: g/G.

In case you've never used a pager before, please keep calm under the circumstance of realizing that ctrl-c/ctrl-d does not quit. Please press q :P


For people on a Unix system it will look for configuration in ~/.config/gelim/config.toml.

Gelim follows XDG specification for deciding where to find config and where to store data files.

Though you do not need a configuration file to have gelim working.

# example config

prompt = "-->"            # default: "%U" (the full url of
                          # the current page), more info
                          # below

startURL = "example.com"  # default: ""

# will be put in LESS environment variable
lessOpts = "-FSXR~"       # default: "-FSXR~ -P pager (q to quit)"

searchURL = "geminispace.info/search"  # this is the default

clipboardCopyCmd = "pbcopy"  # Example for MacOS. default = "" (unset)

maxRedirects = 5

index0shortcut = -1  # default: unset (0). an alias for link index 0


Example for linux with xclip: xclip -sel c

Contents to be copied will be piped to the command as stdin.


  • 0: Always confirm redirects
  • 0: Ask to confirm redirects after a set number of redirects

  • <0: Never confirm redirects. (Please see this section for behavior details)


How gelim should treat link index argument "0", please see this section for behavior details.

#Prompt format options

You can use a number of placeholders for your prompt (like PS1 in bash):

  • %U: Full url of current page including scheme (gemini://example.com/foo/bar)
  • %u: Full url of current page without scheme (example.com/foo/bar)
  • %P: Absolute path of the current url (/foo/bar)
  • %p: Base path of the current url (bar)

Use %% for a literal percent character, and percent-prefixed option that is not supported will be ignored and presented literally.

The query part of the URL will be stripped for all options, for security reasons. (If the input was to be sensitive -- 11 status code -- the full query percent-encoded would be printed as the prompt, which could mean revealing passwords, etc. Hence the query including the ? is stripped.)

Here are some examples:

config    resulting prompt
-------   -----------------
"%U>"     "gemini://example.com/foo/bar> "
"%P %%"   "/foo/bar % "
"%z>"     "%z> "
"%%%% $"  "%% $ "

#A note about the pager

Gelim requires less(1) for paged output. If you don't have that installed, or is on windows, it will print the page directly and you'll have to scroll the page yourself (like AV-98). This is a bug and will be fixed in the near future.

#Mouse support

Add --mouse (if your version of less supports it) to lessOpts option in your config file.

#Search in page

Type /<your search query> when less is running. See less(1) for more information.

#CLI Options

~> gelim --help
Usage: gelim [FLAGS] [URL]

  -h, --help             get help on the cli
  -i, --input string     append input to URL ('?' + percent-encoded input)

  -I, --no-interactive   don't go to the line-mode interface

  -s, --search string    search with the search engine (this takes priority over URL and --input)

  -v, --version          print the version and exit

For help on the TUI client, type ? at interactive prompt, or see gelim(1)



~> gelim -s "astrobotany"

Test your awesome, boring, classic, totally OG CGI scripts (exits immediately)

~> gelim example.org/cgi-bin/greet.sh -Ii 'world'
Hello, world!


Use it in scripts to show outputs in stdout

#Behavior details

A good way to master some software is to know how it works from the program's perspective.

Let's take a look at some UX details from various parts of gelim that could cause confusion.

Links on a page are numbered starting from 1. If a page has 3 links, the link indices are 1, 2, and 3.

You can simply type 1, 2, or 3 at the line-mode prompt directly to visit them.

Negative arguments

-1 specifies the last link, -2 the second-last link and so on.

This pattern is applied for ALL commands that take in a link index as argument, such as link, tour, history, editurl.

Multiple arguments

Commands link and tour supports multiple link index arguments, for example:

> link 1 2
> tour 3 4 5

What they do with those links is dependent on what the command is for.

Index 0

This is undefined by default, but can act as a shortcut, set in config index0shortcut.

A hint is printed when you do not set this config value, and you try to use a 0 for link index:

> link 0
[ERROR] Behaviour for index 0 is undefined.
You can use -1 for accessing the last item, -2 for second last, etc.
Configure the behaviour of 0 in the config file.
Example: index0shortcut = -1, then whenever you use 0 it will be -1 instead.
This works for commands history, links, editurl, and tour.


At the moment, ranges of link indices only work for command tour.

Ranges can be specified with an upper bound and a lower bound, separated by a comma. Both bounds can be omitted.

The default value of upper bound is the first link index, and the default value of lower bound is last link index.

Bounds are inclusive.

Naturally, if both bounds are excluded, all links on current page are selected.

The configuration option to set the maximum allowed automatic redirects is maxRedirects. This is set to 5 by default (following RFC-2068), meaning gelim will follow redirects 5 times, after which, if there are further redirects, user will be prompted for what to do.

The command to view the history of redirects following current URL is redirects.

Special values:

  • 0: Ask for input for all redirects
  • <0 (negative): Automatically follow all redirects

Due to implementation and resource limitations, gelim cannot practically follow an infinite number of redirects, nor can gelim save the history of all previous redirects and show them all in the redirects command.

The command shows a maximum of 10 most recent redirect URLs.

Once the number of unprompted redirects reaches 20, gelim aborts and prints the 10 most recent redirects.

If you wish, you can still copy the last URL from the output and visit the URL as normal.

What happens when the max number of redirects is reached

Consider the example where maxRedirects is set to 2 in the configuration file.

This is the behavior of following the redirhell torture test URL:

So, with that said, the first link is to the "Redirection From Hell" test, a test
of a series of temporary redirects, always. The second link is to the next test.

 [1] Redirection From Hell
 [2] 0023
gemini://gemini.thebackupbox.net/test/torture/0022> 1
[WARNING] Max redirects of 2 reached
1 gemini://thebackupbox.net/test/redirhell/20190
2 gemini://thebackupbox.net/test/redirhell/25942

Redirect to:
[y/n]> y
[WARNING] Max redirects of 2 reached
1 gemini://thebackupbox.net/test/redirhell/9114
2 gemini://thebackupbox.net/test/redirhell/4356

Redirect to:

After 2 redirects, the user will be prompted and the count of redirects resets, meaning the user saying "y" to prompt is equivalent to the user opening a new link of the said URL.

If the total number of times the user gets redirected for a particular website is 10, and maxRedirects is set to 3, the user will be prompted 3 times on whether to follow a subsequent redirect.

  1. 3 redirects followed
  2. Continue? yes
  3. 3 redirects followed
  4. Continue? yes
  5. 3 redirects followed
  6. Continue? yes
  7. 1 redirect followed
  8. the page loads and is displayed

Here is an example for the behavior of redirects command, following the case where maxRedirects is set to 2:

So, with that said, the first link is to the "Redirection From Hell" test, a test
of a series of temporary redirects, always. The second link is to the next test.

 [1] Redirection From Hell
 [2] 0023
gemini://gemini.thebackupbox.net/test/torture/0022> 1
[WARNING] Max redirects of 2 reached
1 gemini://thebackupbox.net/test/redirhell/32043
2 gemini://thebackupbox.net/test/redirhell/1544

Redirect to:
[y/n]> n
gemini://gemini.thebackupbox.net/test/torture/0022> redir
1 gemini://thebackupbox.net/test/redirhell/32043
2 gemini://thebackupbox.net/test/redirhell/1544


You can use help <cmd> at the prompt to view usage information for a particular command. If there's anything that is confusing or a pattern/behavior that is hard to remember, let me know!

Of course, a last resort could be studying the source code directly, remember to look at the corresponding version which you built gelim from.

Gelim = "gemini" + "line-mode"-like interface

Pronunciation = Ge like "Jelly", lim like "limits"

(Imagine the Ubuntu jellyfish learning calculus)


once upon a time, a curious programmer stumbles upon ssh kiosk@gemini.circumlunar.space. then tries out bombadillo and amfora...

"how do I move? most pagers allow pressing space... oops that opens the command prompt"

"ok so I can press a number to go to that link... hmm how about 10, 11, 12 etc? is it like vim where it has a timeout for numeric keys? oops, looks like only single digits are supported..."

"wait so, single key press for single digit link indices, use a command prompt for all others? okay sure"

Tries out AV-98

"I love the interface!"

"wait why is it scrolling to the bottom of the page already? like our good-ol cat?"

"I have to manually scroll my terminal screen? I have to reach for my mouse? otherwise I have to have a geeky window manager setup?"

"typing go command each time and navigating by relative URLs are a bit of a pain"


"ok you know what: all links are commands. all link indices are commands. all relative URL paths are commands. we shall put all content longer than screen's height into a pager everyone's familiar with. just like git (CLIs), but without typing the git!"

the programmer sets off to code...
