Tigr-m2/modula2/README.md

A GNU Modula-2 binding of the tigr graphic library

I did this because I needed a graphic library to follow the UI tutorial here :

https://nakst.gitlab.io/tutorial/ui-part-1.html

The tigr library repository is here:

https://github.com/erkkah/tigr/tree/master

I used also the h2d utility found in the XDS distribution, to check my choices when I tralslated the C headers into Modula-2 ones.

Instructions

To compile the examples, use this command :

• Compiling tigr.o
  

gcc -c tigr.c

• Compiling helper.o
  

gm2 -fiso -c helper.mod

• Compiling an example
  

gm2 -fiso -I ../../ ../../tigr.o ../../helper.o program.mod -o program -s -lGL -lX11

microui port

This repository also contains an ISO Modula-2 port of microui v2.02 (immediate-mode UI, by rxi) together with a tigr-rendered demo.

• Compiling the microui modules (from modula2/)

gcc -c ../tigr-master/tigr.c -o tigr.o gm2 -fiso -c helper.mod gm2 -fiso -I. -c microuiHelpers.mod gm2 -fiso -I. -c microui.mod

• Building the interactive demo (from modula2/examples/microui-demo/)

gm2 -fiso -I ../../ ../../tigr.o ../../helper.o

   ../../microuiHelpers.o ../../microui.o \
   microui-demo.mod -o microui-demo -lGL -lX11

./microui-demo

• Building the off-screen smoke test (writes microui-demo.png)

gm2 -fiso -I ../../ ../../tigr.o ../../helper.o

   ../../microuiHelpers.o ../../microui.o \
   microui-headless.mod -o microui-headless -lGL -lX11

./microui-headless

microui-demo shows windows, headers, tree nodes, buttons, a popup, checkboxes, sliders, a text box and a log panel; press ESC to quit. See ANALYSIS.md for the GM2-specific adaptations and bugs worked around.
