TextMate2 Golang Bundle

If you’re still using TextMate 2 in 2025 and developing with Go, this TextMate bundle will be a game-changer for you! 🚀

Installation

You need go installation:

brew install go golangci-lint

Check if your go installation is ok?

$ go version
go version go1.24.0 darwin/arm64

Now clone this repo:

cd ~/Library/Application\ Support/TextMate/Bundles/
git clone git@github.com:vigo/textmate2-golang.git TextMate2-Golang.tmbundle

After clone, the bundle should normally appear in the pull-down menu, meaning the installation is complete. If it doesn’t appear, restart TextMate.

You need to set TM_GO and TM_GOPATH TextMate variables:

defaults write com.macromates.TextMate environmentVariables \
    -array-add "{enabled = 1; value = \"$(command -v go)\"; name = \"TM_GO\"; }"

defaults write com.macromates.TextMate environmentVariables \
    -array-add "{enabled = 1; value = \"$(go env GOPATH)\"; name = \"TM_GOPATH\"; }"

You need to set PATH manually from TextMate > Settings > Variables:

PATH    "${TM_GOPATH}/bin:/opt/homebrew/bin:${PATH}"

You can also set manually from your global or project based .tm_properties file, I prefer this way:

TM_GO=/path/to/go/libexec/bin/go  # result of command -v go
TM_GOPATH=/path/to/go             # result of go env GOPATH
PATH="${TM_GOPATH}/bin:/opt/homebrew/bin:${PATH}"

It’s not possible to execute shell command in .tm_properties therefore you need to set values by your hand!

If you are an old/aged developer like me :) you can set bigger fonts via:

defaults write com.macromates.TextMate NSToolTipsFontSize 24

You need to install go related tools, all are optional:

goimports: Auto adds required imports.
gofumpt: Shows gofmt errors but stricter.
golines: Breaks long lines even long comments.
shadow: Checks variable shadowing.
fieldalignment: Auto fixes struct field alignments.
golangci-lint: Fastest linter for Go!

go install golang.org/x/tools/cmd/goimports@latest
go install mvdan.cc/gofumpt@latest
go install github.com/segmentio/golines@latest
go install golang.org/x/tools/go/analysis/passes/shadow/cmd/shadow@latest
go install golang.org/x/tools/go/analysis/passes/fieldalignment/cmd/fieldalignment@latest

You can install tools according to your feature toggles with using ⌥ + I (Option + I).

Usage

Open your go projects and hit Save

Bug Report

Please set/enable the logger via setting ENABLE_LOGGING=1. Logs are written to the /tmp/textmate-golang.log file. You can tail while running via; tail -f /tmp/textmate-golang.log in another Terminal tab. You can see live what’s going on. Please provide the log information for bug reporting.

After you fix the source code (next run) bundle removes those files if there is no error. According to you bug report, you can tail or copy/paste the contents of error file to issue.

Also, while running bundle script (which is TextMate’s default ruby 1.8.7), if error occurs, TextMate pops up an alert window. Please add that screen shot or try to copy error text from modal dialog.

Logger output should look like this:

Keep in mind that when logging is enabled, there may be some performance degradation due to file I/O operations.

If you are still using TextMate like me, I eagerly await your comments, bug reports, and feature requests.
