Persistent store with Git semantics: lazy reads, delayed writes, content-addressing
irmin/test/cram: add info.t and tree.t for CLI coverage
info.t exercises [irmin info] against a real repo: store-level output
(backend / branch / list), file-level output (size), and scrubs the
sandbox path out of the [Store:] / [File:] lines. Leaves the column
alignment intact on purpose — it's a visible contract.
tree.t exercises [irmin tree]: root-level recursive listing, subpath
listing, JSON output per entry, and the "path not found" non-zero
exit.
Both follow the skill: directory-form [.t/run.t], literal expected
output with a sed scrubber for the one path-dependent line, no glob/
regex patterns.

irmin info - show store or file information
2

3
+
With no argument, [info] reports on the current repository: store path,
4
+
backend, default branch, and branch list. With a file argument, it
5
+
reports on the file (size, plus CAR metadata when the extension is
6
+
[.car]).

Set up a small Git-backed repository with two branches:
9
+
10
+
$ mkdir testrepo
11
+
$ cd testrepo
12
+
$ irmin init . 2>&1 > /dev/null
13
+
$ irmin set README.md '# Hello' -m 'init' 2>&1 > /dev/null
14
+
$ irmin checkout -c feature 2>&1 > /dev/null
15
+
16
+
Store-level info. The [Store:] path is scrubbed because it contains
17
+
the sandbox cwd:
18
+
19
+
$ irmin info | sed "s|Store:.*|Store: PATH|"
20
+
Store: PATH
21

Backend: git
22

Branch: main

Branches: 2

feature
25

26

File-level info on a plain text file just shows size:
28
+
29
+
$ echo 'hi' > plain.txt
30
+
$ irmin info plain.txt | sed "s|File:.*|File: PATH|"
31

File: PATH

irmin tree - show the branch tree as a nested listing
2
+
3
+
[tree] walks the current branch from the root (or from an optional
4
+
subpath argument), printing every file and directory with indentation
5
+
that mirrors the nesting depth. Directories are marked with a trailing
6
+
slash and coloured blue on a TTY; we run with [TERM=dumb] so the
7
+
output is plain text.

Set up a repository with a nested layout:
10
+
11
+
$ mkdir testrepo
12
+
$ cd testrepo
13
+
$ irmin init . 2>&1 > /dev/null
14
+
$ irmin set README.md 'top-level' -m c1 2>&1 > /dev/null
15
+
$ irmin set src/a.ml 'let a = ()' -m c2 2>&1 > /dev/null
16
+
$ irmin set src/sub/b.ml 'let b = ()' -m c3 2>&1 > /dev/null
17
+
$ irmin set docs/intro.md '# Intro' -m c4 2>&1 > /dev/null
18
+
19
+
Full tree from the root. Files are listed flat at their level; directory
20
+
names carry the trailing slash and are indented one extra step for each
21
+
nested directory:
22
+
23
+
$ irmin tree
24
+
README.md
25
+
docs/
26
+
intro.md
27
+
src/
28
+
a.ml
29
+
sub/
30
+
b.ml
31
+
32
+
Subtree starting at [src/] — anything above src/ is hidden:
33
+
34
+
$ irmin tree src
35
+
a.ml
36
+
sub/
37
+
b.ml
38
+
39
+
JSON output gives one object per entry with a [type] discriminator.
40
+
Order matches the human output:
41
+
42
+
$ irmin tree -o json src
43
+
{"path":"a.ml","type":"file"}
44
+
{"path":"sub","type":"dir"}
45
+
{"path":"sub/b.ml","type":"file"}
46
+
47
+
Unknown path exits non-zero and prints an error line:
48
+
49
+
$ irmin tree nonexistent
50
+
✗ Path nonexistent not found
