bug: version scope colid with template

[tchernomax]

[tools."pipx:ansible"]
version = '''{{ exec(command=`grep -m1 'ANSIBLE_VERSION: ' .gitlab-ci.yml`, cache_duration='10m') | … }}'''

  | ^^^^^^^^^^^^^^^^^^^^^^
invalid prefix: {{ exec(command=`grep -m1 'ANSIBLE_VERSION

This is because tool version is parsed before being templated:

mise/src/cli/args/tool_arg.rs

Line 71 in f336df4

Some((p, _)) => bail!("invalid prefix: {}", style::ered(p)),

Your diagnosis was exactly right, and it is fixed — #11580, merged 2026-08-02.

The version's selector was parsed at TOML-deserialize time, before templates render, so a template containing a colon got split mid-expression. The fix keeps the version string un-rendered until templating is done, and only then splits it.

Two things the investigation turned up that are worth recording here:

• It is not template-specific. "npm:cowsay" = "1.2.3:x" fails the same way, with invalid tool: invalid prefix: 1.2.3. The colon was always the trigger; a template just makes it easy to hit one.
• It is not a regression. Colon-free templates work on every release back to v2025.7.0, so nothing broke this — it had never worked.

Not in a release yet: v2026.8.0 was cut a few hours before it merged, so this lands in the next one. Your grep -m1 'ANSIBLE_VERSION: ' example will parse as written from then on.

Great.
Thanks
