🎀 Name 🎀

ctags-lang-julia — literally just a pile of random notes about tagging Julia source code with Universal-ctags 💖 (yep, this is the ctags-lang-julia(7) page from the Universal-ctags manual, iykyk)

🌸 DESCRIPTION 🌸

This man page gathers random notes about tagging Julia source code. That's it, that's the vibe — no big overarching thesis, just notes, bestie 🫶

🦋 TAGGING import AND using EXPRESSIONS 🦋

💜 Summary 💜

using X

• name: X — kind: module — role: used — other noticeable fields: N/A

using X: a, b

• name: X — kind: module — role: namespace — other noticeable fields: N/A
• name: a, b — kind: unknown — role: used — other noticeable fields: scope:module:X

import X

• name: X — kind: module — role: imported — other noticeable fields: N/A

import X.a, Y.b

• name: X, Y — kind: module — role: namespace — other noticeable fields: N/A
• name: a — kind: unknown — role: imported — other noticeable fields: scope:module:X
• name: b — kind: unknown — role: imported — other noticeable fields: scope:module:Y

import X: a, b

• name: X — kind: module — role: namespace — other noticeable fields: N/A
• name: a,b — kind: unknown — role: imported — other noticeable fields: scope:module:X

🌈 Examples 🌈

Okay so first up, "input.jl":

using X0

and "output.tags" with --options=NONE -o - --extras=+r --fields=+rzK input.jl:

X0      input.jl        /^using X0$/;"  kind:module     roles:used

The --extras=+r (or --extras=+{reference}) option is needed for this tag, since it's a reference tag — because module X is not defined here, it's defined in another file. Enabling the roles: field with --fields=+r is for recording that the module is "used", i.e. loaded by using 👑

Next one, "input.jl":

import X1.a, X2.b, X3

and "output.tags" with --options=NONE -o - --extras=+r --fields=+rzKZ input.jl:

X1      input.jl        /^import X1.a, X2.b, X3$/;"     kind:module     roles:namespace
X2      input.jl        /^import X1.a, X2.b, X3$/;"     kind:module     roles:namespace
X3      input.jl        /^import X1.a, X2.b, X3$/;"     kind:module     roles:imported
a       input.jl        /^import X1.a, X2.b, X3$/;"     kind:unknown    scope:module:X1 roles:imported
b       input.jl        /^import X1.a, X2.b, X3$/;"     kind:unknown    scope:module:X2 roles:imported

So like… why do X1 and X2 have role "namespace", while X3 has role "imported"? 💀 It's because the symbol a in module X1, and b in module X2 are brought to the current scope, but X1 and X2 themselves are not. We use the "namespace" role for such modules.

X3 is different. The symbol X3, together with all exported symbols in X3, is brought to current scope. For such modules, we use "imported" or "used" role depending whether they are loaded by import or using.

Also, notice that a and b have the "unknown" kind. This is because we cannot know whether it's a function, constant, or macro, etc. 🙈
